Reinforced concrete rings for sewerage, weight. Main characteristics and dimensions of concrete rings for sewerage

Reinforced concrete rings are products made from a composite material - reinforced concrete, which includes two main components: concrete and steel.

Rings can have different sizes and diameters and are produced by casting followed by hardening of the mixture.

This is what reinforced concrete rings look like

Despite the fairly wide scope of their application in construction, reinforced concrete rings are most often used for sewerage in private houses. Z

Here, wastewater receivers - storage wells or septic tanks - are equipped with full-fledged treatment facilities.

Also, inspection sewer wells are made from concrete rings, which are located in places where pipes are laid every 30-50 meters.

What is the classification of reinforced concrete rings

If we talk about classification, it should immediately be noted that all concrete rings for sewerage are divided into two large groups: standard and Euro-rings.

In the first option, we are talking about ordinary products, which, when installing wells, are installed on top of each other, fastened at the joints using cement mortar and additional metal brackets.

Euro-rings are initially equipped with special locks or folds that provide a strong connection of several elements.

At the same time, the diameter of Euro-rings can be larger than that of conventional reinforced concrete products.

Standard and Euro rings

Sewer rings are also divided according to the grade of concrete used in their production.

In this case it will be like this: B25 and higher.

Frost resistance indicators cannot be less than F-100, and water resistance will be marked W-4.

Reinforced concrete rings for your sewerage

It should be noted that reinforced concrete rings for sewerage are classified according to the features of their design.

Here you should pay attention to the letter markings.

For example, if products are designated by a combination of letters KS, this means that you are looking at wall rings.

They are used in the arrangement of sewer systems for the construction of septic tanks and wells.

If you see markings like KSD, this means that you are being offered an additional wall ring.

What are the sizes of reinforced concrete rings for sewerage?

If we talk about the sizes of reinforced concrete rings, in general, then you can see these indicators in the same product markings after the letters mentioned above.

Manufacturers mostly prescribe dimensions in decimeters.

For example, if we decipher the designation KS-10-6, this means that the diameter of the product in this case is 10 dm or 1 meter.

Accordingly, the height of the ring will be equal to 0.6 m.

Ring sizes KS-10-6

It should be noted that if we talk specifically about the dimensions of concrete rings for sewerage, then everything will be much simpler.

The standard height of one product is 90 cm. The diameter can vary between 1-2 meters.

But, if you need to build a smaller structure or use non-standard rings, you should pay attention to products marked KSD.

The additional wall rings have a height of 30 and 60 cm, allowing, as a result of their combination with conventional CS, to obtain a well of the required height.

How to calculate the volume of reinforced concrete rings

In order to determine the volume of sewer well rings, you should use a special table of the ratio of sizes and volume indicators.

Here you can see such indicators as the internal diameter of the product, its wall thickness, and volume.

Accordingly, in order to determine which reinforced concrete rings are needed for sewerage, you first need to calculate the total volume of the well.

Table of reinforced concrete rings

Calculations will be carried out using a very simple formula.

Here you need to multiply three indicators:

• the number of people permanently living in the house. Let's take 5 for example;
• daily water requirement per person in liters. Today this figure is 200 liters;
• the number of days during which the wastewater is completely processed. This is 3 days.

Reinforced concrete rings for 3 cubic meters together

Thus, by making a simple calculation: 5*200*3, we get 3000 liters.

Converting this figure into cubic meters, we get 3m 3.

This is exactly the volume that a sewer well should have for a family of 5 people.

Calculation of internal volume

The internal volume of the ring is calculated using a simple formula. Here you need to multiply R 2 - the radius by the height of the product and by 3.14 - a constant value.

Accordingly, to obtain the radius of the ring, we need to perform the calculation in reverse order.

We divide the total volume by 3.14 and the height of the well, which in our case is 2.3 meters with a total depth of 2.5 meters.

This gives the formula: R 2 =3/2.3/3.14. As a result, the radius will be 0.65 m.

It turns out that the diameter of the sewer well should be 1.3 m. Such products are not produced, so we take rings with a diameter of 1.5 m.

Advantages and disadvantages of reinforced concrete rings

Before installing a sewer system made of concrete rings, you should consider all the advantages and disadvantages of these products.

The benefits will be as follows:

Reinforced concrete rings - strength, tightness, long service life

• fairly high strength indicators;
• simple and extremely quick installation;
• high tightness, especially with additional waterproofing;
• long service life;
• affordable price.

Of course, there are also disadvantages in this case, which you also need to know when arranging a sewer system from rings made of reinforced concrete.

These include the following points:

Heavy weight, installation by machinery

• the need to rent special equipment to transport the material;
• the heavy weight of the products makes it impossible to install them manually, forcing you to seek the help of special equipment.

In any case, there are more advantages than disadvantages, and accordingly, a concrete sewer well can be called one of the most suitable options.

It remains to consider the sequence of installation work.

How to install concrete rings

You don't need to hire specialists to get the job done. You can do everything yourself.

Installation of sewer rings will be carried out in the following stages:

If there is supposed to be a second well where settled water will flow, installation of sewer rings will be a little more complicated.

At a level of approximately 50 cm from the ground surface, you need to make a hole in the concrete ring where the pipe will be connected.

Through it, the wastewater will flow into the next well.

The service life of a septic tank made of reinforced concrete rings is 20-30 years

If we talk about service life, a sewer system made of reinforced concrete rings can work properly for about 20-30 years if its installation is done correctly.

A properly equipped sewage system is the key to complete comfort. Even in a small summer cottage, you can enjoy all the benefits of civilization by equipping a cesspool made of concrete rings of different diameters on the site.

Reinforced concrete rings are widely used for the construction of sewer systems - inspection wells or cesspools. The use of rings is considered the simplest and most convenient way to arrange a sewerage system.

The rings are made of reinforcement and concrete, they are very durable and are used primarily for durable work.

A sewer system equipped with reinforced concrete rings is reliably protected from various weather conditions and protects groundwater from sewage leakage.

There are two types of rings - Euro rings with a lock and ordinary reinforced concrete rings. The second type of rings is connected to each other with cement mortar and iron staples.

Advantages of using reinforced concrete rings:

• Long product life;
• Do not allow moisture to pass through;
• Easy installation and operation;
• Low cost;
• Can be used to equip sewerage systems, small tunnels, power lines and heating networks;
• Protect from groundwater.

The disadvantages include purely technical aspects - the heavy weight of reinforced concrete rings requires transportation in a large car, and their installation is only possible using special equipment.

Classification and volume of reinforced concrete rings

These rings are made of heavy concrete B25, frost resistance of which is F-100, water permeability of W4. Reinforced concrete rings are marked, according to which the classification of the ring can be determined.

Reinforced concrete rings are divided into prefabricated, additional, with a lid, with a lock and with a bottom.

First, the marking indicates the type of structure: KS - wall ring, KSD - wall ring with a bottom. After the type, the size of the ring is written, the first group of numbers indicates the diameter of the ring, after the hyphen - the height of the product. For example, KS-15 designates a wall ring with a diameter of 1500 cm.

When installing a cesspool on a site, first of all, the size of future sewage is taken into account. Depending on the depth of the sewage pit, the required number of reinforced concrete rings and their types are calculated.

The standard height of the rings is 90 cm, but if necessary, the design can be supplemented with rings of other sizes. Depending on the needs, the diameter is selected - from 70 to 200 cm. The thickness of the concrete wall is 7-14 cm.

The strength of the structure largely depends on the bottom well ring - experts recommend installing a ring with a bottom. Next come the wall rings and the cesspool is closed with a lid with a hatch. The diameter of the septic tank elements must be the same everywhere, otherwise the structure will be unstable and sewage may leak into the ground.

The volume of a concrete ring is 1 meter: the nuances of building septic tanks

A single-chamber septic tank made of reinforced concrete rings must have a bottom and a lid. Such a cesspool is considered ineffective; it is most often installed in the country.

A drainage pit is installed at a distance of no more than 20 m from a residential building. The further away the septic tank is, the more pipes will have to be laid from the sewer system in the house to the reinforced concrete septic tank. In this case, the minimum distance to residential buildings is 5 m. When installing a septic tank, you should take into account the number of people who will use the sewerage system. On average, a person uses approximately 200 liters of water per day for sewage.

When choosing rings made of reinforced concrete, it is important to know how many liters of waste water this structure can accommodate. It is believed that the minimum volume of a septic tank made of rings is 6 cubic meters. To calculate the volume of a reinforced concrete ring, you need to multiply the number of residents by 200 liters, and multiply the resulting amount by 3 (the period of time during which the wastewater is processed in the pit). To obtain the volume of the ring, divide the final amount by 1000. Based on the tables on the Internet, select a reinforced concrete ring with a suitable diameter. One standard 90 x 150 cm ring holds approximately 1.59 liters of water or waste.

When installing a septic tank from rings, you need to remember that the surface on which the rings are placed must be strictly horizontal.

If it is not possible to install a lower ring with a bottom, you can fill it with a dense layer of crushed stone and fill it with cement mortar. The top of the septic tank is covered with a ring with a hermetically sealed cast-iron sewer hatch.

Cesspool made of concrete rings without a bottom: do-it-yourself installation

Before you start laying the rings, you need to prepare a pit 3 meters deep for the cesspool. Its width should be slightly larger than the diameter of the reinforced concrete rings selected for the septic tank.

You can dig a hole for a foundation pit yourself using shovels, or you can hire special equipment to get the job done faster.

The bottom of the pit must be leveled with sand, on top of which a concrete ring with a bottom or an ordinary wall ring is installed.

How to install a septic tank from reinforced concrete rings:

1. Install the first ring. Check that it does not lean to the side.
2. Having installed the next wall ring, fill the space between the septic tank and the pit.
3. Gradually build a septic tank, not forgetting to check the level of installed reinforced concrete rings.
4. Seal the joints between the rings with a solution of cement and sand.
5. Using a hammer drill or grinder, make holes for the sewer pipes. The drain pipe from the house is installed at a slight angle.
6. If the sewerage system consists of several septic tanks, in addition to the drainage pipe, you need to lay a pipe connecting the septic tanks. This pipe is located 20-30 cm below the waste pipe.
7. To prevent runoff from getting into the ground, it is important to choose the right waterproofing. For this, bitumen or polymer mastic is used.
8. The final stage is installing covers on the septic tank. After the joints have dried, you can begin using the cesspool.

A septic tank made of reinforced concrete rings does not require special operating rules, but it is important to clean it on time and use special bacteria to better process wastewater.

How to calculate the volume of a ring (video)

The performance of a reinforced concrete septic tank largely depends on the quality of the materials from which it is made. All items must be correctly labeled. By observing all the nuances and installation technologies, the waste pit will last for quite a long time.

This question often visits those who are involved in construction, repair or arrangement of suburban areas, but it also happens that the average person has to look for an answer to it. In our article we will try to help you with this, we will tell you not only about the formulas and calculations themselves, but we will talk a little about the concrete rings themselves.

Reinforced concrete rings

These are special designs for constructing wells of different calibers, which are most often used in external water supply and sewerage networks.

The production of standard products is carried out in factory conditions from high-quality concrete in strict compliance with GOST “Reinforced concrete plumbing structures”.

The process of producing concrete rings is not particularly difficult; for this you need:

• Reinforced steel with a diameter of up to 10 mm.
• High quality concrete.
• Casting mold.

For the construction of wells, they are produced in standard sizes with markings reflecting the purpose of the ring and its standard size. We will talk about the varieties below.

As for how the price of each specific product is calculated, it is necessary to understand how many cubes are in a concrete ring; in fact, the more, the higher the cost.

Calculation of reinforced concrete support ring

But since there are many different options on the construction market, take, for example, the support ring KO 6 - the volume of concrete of the product is calculated as follows:

• First, we need to write down the parameters (dimensions), in this case they will be equal to the following indicators - 840 x 580 x 70 mm.
• Let's calculate the area of ​​a circle with a larger diameter using the formula - ¼ P d2 = 1/4 x 3.14 x (0.84 x 0.84) = 0.553896 m2. Where P = 3.14, and d is the outer diameter (in our case 840 mm). Let's convert everything into meters.
• Now, using the same formula, we calculate the area of ​​a circle with an internal diameter - ¼ x 3.14 x (0.58 x 0.58) = 0.264074 m2.
• Let's find out the area of ​​the product itself; to do this, we need to subtract the area with the inner diameter from the area of ​​the circle with the outer diameter 0.553896 - 0.264074 = 0.289822 m2.
• By multiplying the area by the height, we find out its volume - 0.289822 x 0.07 = 0.02028754 m3.

So, we calculated the volume of concrete for the support ring KO 6, as you can see, there is nothing complicated about it, the main thing is to know the formula and parameters of the product. However, it is always easier to make calculations than to build a well with your own hands; special equipment is needed here.

Types of reinforced concrete products for wells

We present the parameters of all types of manufactured rings for clarity (the parameters will be described in the following order - height, wall thickness, internal diameter and weight):

Note! The KS marking means the following – wall ring.

• KS-7-1, 10 cm, 8 cm, 70 cm, 46 kg.
• KS-7-1.5; 15 cm, 8 cm, 70 cm, 68 kg.
• KS-7-3, 30 cm, 8 cm, 70 cm, 140 kg.
• KS-7-5, 50 cm, 8 cm, 70 cm, 230 kg.
• KS-7-6, 60 cm, 8 cm, 70 cm, 250 kg.
• KS-7-9, 90 cm, 8 cm, 70 cm, 410 kg.

• KS-7-10, 100 cm, 8 cm, 70 cm, 457 kg.
• KS-10-5, 50 cm, 8 cm, 100 cm, 320 kg.
• KS-10-6, 60 cm, 8 cm, 100 cm, 340 kg.
• KS-10-9, 90 cm, 8 cm, 100 cm, 640 kg.
• KS-12-10, 100 cm, 8 cm, 120 cm, 1050 kg.
• KS-15-6, 60 cm, 9 cm, 150 cm, 900 kg.
• KS-15-9, 90 cm, 9 cm, 150 cm, 1350 kg.
• KS-20-6, 60 cm, 10 cm, 200 cm, 1550 kg.
• KS-20-9, 90 cm, 10 cm, 200 cm, 2300 kg.

Please note that products weighing more than 100 kilograms have reinforced ears.

A product marked, for example, KS-10-6 is called a complete wall ring with dimensions:

• Height-60 cm.
• Inner diameter - 100 cm.

There are products marked KO (support ring), these products are found in the following version:

• KO-6, height - 7 cm, internal diameter - 58 cm, external diameter - 84 cm, weight - 60 kg.

Another modification is a lining under the hatch of wells (ring K 1a the volume of concrete is calculated according to the following parameters):

• K - 1a, height -18 cm, internal diameter - 58 cm, external diameter - 100 cm, weight - 160 kg.

Marking PP means floor slab

Additional products allow you to more accurately regulate the height of the well, in some cases leveling it with the ground, in others making them more visible. Installing concrete lining elements on the well covering slab will help raise the hatch above its surface.

This eliminates:

• Flow of rain and melt water into the well.
• Vehicle collision with a manhole if the well is located under the roadway.
• Flooding of the hatch itself.

One of the important parameters of such a product is the volume of the concrete ring - 1 cubic meter, this is the unit of measurement for all such calculations.

Advice! You may often come across advertisements for the sale of used concrete products, including wall supports for a well; our advice to you is to study the product before buying. In particular, inspect the interior walls, where unevenness and different shades of concrete may be visible (this is how unscrupulous sellers seal cracks).

Conclusion

We hope that the above instructions will help you find the correct answer to the question posed. If any difficulties arise in this process, you can always use a free electronic calculator, which can be found on the Internet.

In the videos presented in this article you will find additional information on this topic.

The installation of a sewerage system and a well is a prerequisite in private and multi-storey buildings. Such structures are subject to certain requirements, so they must fully comply with sanitary and hygienic standards. In addition, when installing a well treatment system for a country house, any person expects that the structure will last for decades, serving faithfully.

Therefore, the optimal solution when performing such work would be to install a concrete ring. This product is made of strong and durable material that can last almost forever, provided that the ring is correctly selected and the installation is carried out in compliance with all requirements. Therefore, it makes sense to consider the features of concrete rings, understand the size range and installation methods.

What types of rings are there? Types and purpose

Well rings are round reinforced concrete structures used for arranging utility lines buried below ground level. Depending on the structure being constructed, the following types of rings are used:

Sewage and water intake.

Products for laying underground cable electrical networks.

Collectors.

Gas pipelines and water intakes.

In addition, there are the following varieties on the market:

Rings with flat and locking ends.

Repair.

Additional ones.

Regardless of the type and purpose, products are made of heavy concrete, grades 200-500, reinforcement is being performed.

Production technology

Rings for wells are made from hard concrete, which is poured into the formwork. It is necessary to clarify that the reinforcement is first made from steel wire with a diameter 8-12 mm. Two vertical rods are installed at opposite ends of the structure, which act as lugs for lifting the ring.

The mold is compacted using vibration to prevent the formation of voids. The formwork is removed one day after pouring the concrete. After this, the finished products are stored in open areas. Tempering strength of the ring ( 50% of the given) is gained in approximately 7 days. Full concrete strength is achieved after 28 days.

Advantages and disadvantages of reinforced concrete rings

It's no secret that any building material has its strengths and weaknesses. This feature also applies to finished products. Concrete rings seem ideal, but even they are not without some drawbacks.

The undeniable advantages of reinforced concrete rings include the following:

High quality at an affordable price.

Wide range of sizes.

The ability to quickly install a water supply and sewerage system.

High tightness: tight fit of the seams prevents groundwater from entering the structure.

Long service life: reinforced concrete is neutral to any environment, so it can last at least 100 years.

Structural rigidity: wells made of concrete rings can be installed even on unstable soil.

Obvious disadvantages include the following:

Dimensions and weight: it is impossible to install a concrete ring without the use of construction equipment, which somewhat increases the cost of installation.

Lack of mobility: it is very difficult to move such a well.

You can see that there are more positive features, which explains the steadily growing popularity of concrete rings.

Marking according to GOST. How to read symbols correctly

Each reinforced concrete ring has a marking that determines the scope of application of the product. The symbols correspond to GOST standards, it looks like this:

KLK- products intended for the installation of drains and urban storm sewers.

KVG- rings used for installation of gas pipelines and water wells.

KO- a support ring that forms the foundation of the well.

KS- wall models installed in limited spaces.

KFC- drainage systems and collector networks.

In addition, the ring markings also contain numerical designations.

Decryption example:

KS-7-9. This means a wall ring with wall thickness 70 and height 900 mm.

Standard sizes of reinforced concrete rings

Concrete rings are available in a very diverse range of sizes. Standard product sizes look like this:

Height: 10-100 cm.

Wall thickness: 70-120 mm.

Inner diameter: 70-200 cm.

Specific gravity: 46-2 300 kg.

Thanks to these standard sizes, choosing rings for arranging an individual water supply system is not difficult.

What else is needed? Additional items

It should be noted that installing rings alone will not solve the problem of a high-quality water supply system. In order for the well to meet the requirements, the installation of additional elements will be required. This is not a mandatory condition, but compliance with this rule will help prevent contamination of the system with wastewater, increase its service life, and give the structure a complete look.

For this purpose:

Bottom plates provide a reliable foundation.

Floor slabs - thanks to a narrow hole on top of such a slab, a ring of small diameter is installed, closed with a regular manhole cover.

Additional rings are products of standard diameter, but smaller thickness. Such elements help raise the height of the well to the desired level.

The use of such products ensures maximum tightness of the well and prevents pipes from freezing in winter.

Installation process

In order for the well to meet the established requirements, the installation of the structure must be carried out in accordance with all the rules. Here you need to follow the well-known procedure:

Selecting a location

Water wells and drainage systems are not located close to residential buildings. Average distance from home - approx. 5 meters. There should be no groundwater in the chosen location, otherwise you will have to incur additional costs for sealing. In addition, special equipment must be freely accessible to the installation site.

Pit

To dig a pit, it is better to hire equipment: the depth of the hole should be equal to the height of two rings. Digging such a pit by hand will be very problematic. A drainage cushion made of layers of sand and crushed stone, thick not less than 50 cm.

Rings

For the lower tier, a ring with a solid bottom is ideal; if the product is through, the bottom slab is laid first. The elements are installed on top of each other using a truck crane, the joint is covered with mortar. If the well is mounted on moving soil, the joint can be reinforced with metal staples.

After installing the rings, communications are brought to the well, the necessary connections are made, the foundation pit is filled, the rings are covered with a top slab, and sewer hatches are installed.

Which manufacturer should you prefer?

Concrete rings for wells are produced around 250 companies located throughout Russia. Let's consider 5 trusted manufacturers.

MasterStroy LLC. The company is located in Voskresensk near Moscow, specializes in the sale of core and bulk cement, and is engaged in the manufacture of pressure pipes and reinforced concrete rings.

OJSC Industrial Construction Parts Plant. The company is known in the construction market for more than 45 years, is one of the largest manufacturers of reinforced concrete products in the Tyumen region. The company has its own construction laboratory (accredited), which controls the quality of its products.

LLC "Trading Company Vira". The production line of the enterprise is located in St. Petersburg. The company produces reinforced concrete rings and non-pressure pipes. All products undergo multi-stage quality control.

LLC "Monolit Stroy". The company is located in the Moscow region, engaged in the manufacture and sale of reinforced concrete products with 2007. The product range includes bridge and composite piles, FBS, wall rings, base slabs and manhole covers.

GazoBloki LLC. This is a Voronezh company engaged in the production of ready-mixed concrete, sand-lime and facing bricks, concrete rings and additional elements for them.

It should be clarified that these are far from the only suppliers in the Russian region. The above companies strictly monitor the quality of their products, work directly with suppliers of raw materials, and comply with GOST standards.

Reinforced concrete rings are most often made when developing land plots. Often, owners of suburban areas have to make a ring with their own hands. To do this, you need to know the formulas used for calculations and the features of concrete products. Products manufactured for the well are labeled in accordance with the requirements of state standards. Markings are symbols indicated on the rings by which information about the size and weight of materials can be identified.

For each concrete product produced in accordance with the requirements of state standards, tests are provided that confirm the quality, declared performance characteristics and resistance of the product to negative factors. When summing up, experts take into account water resistance, frost resistance, moisture absorption, and compressive strength.

Reinforced concrete rings

Reinforced concrete rings are special products designed for constructing wells used in water supply systems, as well as for water drainage. The easiest way is to entrust the work on the sewer system of a private house to one of the companies. However, it is necessary to calculate in advance how much money will be spent on this. If you want to save money, you can make a sewer system, which will be based on a concrete ring, yourself. The production of such products is carried out at enterprises in compliance with state standards. When creating, high-quality materials are used, CCD. The manufacture of products involves the use of a special form, concrete and reinforcement, the diameter of which should not exceed ten millimeters.

Reinforced concrete building materials of this type are marked with markings that determine their purpose and standard size. If we talk about how to calculate the cost of a particular product, it is important to take into account the volume of the rings. The higher this indicator, the more expensive the material.

Types of well parts

Well bottoms KCD 10a.

Well bottoms KCD 10a are a necessary part of a prefabricated septic tank. The durability of the product depends on the quality of their manufacture and correct installation. The bottom of KCD 10a is produced in the form of a monolithic reinforced concrete slab with several special hinges. Bottoms of different diameters are available for sale. Donyshko KCD 10a is produced according to the approved standard. The dimensions of the CCD are designed so that the bottom can withstand the load of liquid that accumulates in the container. In doing so, manufacturers take into account possible soil mobility and the impact of groundwater. KCDs are selected according to the diameter of other well parts - KC rings, covers, etc.

Examples of parameters of several types of CC rings (height and weight of CC products):

• KS-7-1; ten centimeters, forty-six kilograms;
• KS-7-1.5; fifteen centimeters, sixty-eight kilograms;
• KS-7-3; thirty centimeters, one hundred and forty kilograms;
• KS-7-5; fifty centimeters, two hundred and thirty kilograms.

Materials KS, KTs, whose weight exceeds one hundred kilograms, must have special ears. A product that is marked, for example, KS10-6, is called a wall product. On sale you can also see materials with the designation KO6 (support ring). Products marked KO6 have a height of seven centimeters, an internal diameter of fifty-eight cm, ext. diameter - eighty-four cm, weight - sixty kg. K06 support products are also used when carrying out work on sites.

Concrete CCs (KO6, KS10) allow you to more accurately determine the height of the container. You can level it with the surface of the ground or make sure that the rings are above the soil level. Installing concrete parts on a special slab will allow you to raise the well hatch. Due to this, it will be possible to prevent the ingress of melt and rain water and flooding of the hatch. The volumes of the rings are important when carrying out calculations for CC. The cubic meter is the basic unit of measurement.
