TP 902-09-46.88. "Rainwater drainage chambers and wells"

A voluminous album with many recommendations and ready-made schemes for designing wells and chambers of storm sewer systems. In a modern city, such systems are very important for the drainage of melt and rainwater from the surface of the territories. Well-coordinated work of storm water inlets, wells and pipelines ensures cleanliness and dryness of streets, durability of the roadway and neatness of neighborhoods. For the installation of storm sewers, several types of reinforced concrete products are required: reinforced concrete pipes, well rings, well bottoms, well overlapping slabs, storm water inlets. These products are universal and unified and are manufactured in accordance with GOST 8020-90 standards.

The modern construction of rainwater wells made of precast concrete parts allows you to significantly save money on delivery and installation, as well as to establish a well-functioning system. Wells and chambers consist of a reinforced concrete storm inlet BO in the form of a tray of a special shape, wall rings of a well with a diameter of 700 and 1000 mm, floor slabs with a KTsP hole, and solid bottoms of a KCD well.

• BO is a reinforced concrete stormwater inlet, which has a tray shape and is designed to collect moisture from the roadsides and transfer it directly to the well.
• KC - classic concrete rings that form the neck of the well. These are traditional solid rings and rings with various combinations of holes for piping through. Numerous shop drawings and ring combinations for construction different types wells and chambers includes Album III Round Wells.
• KTsP is a well slab, a necessary element in the construction of each system with deepening on the basis of round rings. The 120mm thick slabs provide reliable support for the structure.
• KCD - well bottoms 100 mm thick, they act as a base and a sealed base for the structure of the well, preventing the well from shifting.

For the production of elements of wells and chambers, due to the specific microclimate and operating conditions, special heavy concrete is used, which makes it possible to cope with the abundance of moisture and urban chemical reagents. Blocks, well rings and floor slabs have high level hydrophobic and anticorrosive protection, made of dense concrete M200-M300 with a high concentration of additives. Well concrete products that work in storm sewers, as a rule, do not experience serious loads, therefore, reinforcement with steel meshes is sufficient. But the thickness of the concrete layer to the reinforcement and the general class of protection against moisture and corrosion are strictly controlled.

Collection of technical project TP 902-09-46.88includes several albums, which, in particular, relate to the design of various kinds of chambers and wells located on certain sections of pipelines. In our section "GOSTs and SNiPs" you can download a series TP 902-09-46.88and get acquainted with working drawings and design diagrams. In the company "Complex-S" you can buy concrete rings of wells, floor slabs, well bottoms with delivery to your object. For a complete set of stormwater drainage systems, there are also cast iron and polymer-sand hatches and storm water inlets with grates.

Network type selection is requested

If you uncheck the "Select all networks" box, you can specify specific networks of the selected type for building tables. Otherwise, tables will be built for all networks of the selected type.

Then a window is displayed

Some of the columns are closed. They can be expanded by clicking on the title. Clicking again closes the column.

Table variants can be called up in the Table Type area. There are such options for the table of wells for water supply and gravity sewage:

a) Round water supply wells (TP 901-09-11.84 with display of all structural elements).

b) Round sewer wells (TP 902-09-22.84 with display of all structural elements).

c) Round sewer wells (TP 902-09-22.84 with displaying only the present structural elements).

There are 3 tables for B1 and B2; for K1, K2, K3 - three options. For other networks, all options are present, the user himself can choose.

In the second version of the well table (according to GOST) - specifically for the wells of pressure networks - there are the following columns:

When executing a project on external sewerage networks, the project includes a mandatory sheet "Table of sewerage wells".

This table, depending on the construction area, is performed in two ways:

• for the entire territory of Russia (except for Moscow) it can be performed according to
• for Moscow it is performed according to or PP 16-8.

Let's consider both options in order.

Selection of a sewer well according to TP 902-09-22.84.

An example of a sewer well table is shown below:

Column 1 the designations of sewer wells are shown in free form according to your profiles.

Column 2 the mark of the well is shown for soil conditions according to TP 902-09-22.84 (I - for dry, non-collapsing soils, II - for wet soils, III- for collapsing soils). Note: As a rule, on the territory of Russia type II soil. Sometimes III occurs. During my extensive practice, I have never met type I soil. Even if you do not have groundwater, there is always a top water. Those. the type of soil must be taken - II (for vertical water or groundwater in the zone of laying sewage networks.

Column 4 the total depth of the well is shown. This indicator is calculated as follows:

"Full depth of the well" \u003d "Depth of the bottom of the pipe along the profile" + "height of the hatch relative to the ground".

"The height of the hatch relative to the ground" is taken as 0mm for hatches located on the asphalt (brushatka, etc.), it is taken 50-70mm for hatches located in the green urban area, it is taken as 500mm for hatches located in the green unbuilt zone.

Column 6 the depth of the tray is shown. It is determined by TP 902-09-22.84, depending on the type of well, the diameter of the largest pipeline. Typically the tray is 100mm above the largest pipe in the well.

Column 3 the mark of the well is shown. We take it according to TP 902-09-22.84 column 1, table 1, 2, 3, 4. To select the brand of the well, you need to perform several steps:

1. Determine the type of well according to the route plan. Wells are subdivided into linear "KML- ..." (one pipe entered the well and one came out of the well in the same direction) - the selection is carried out according to table 1, TP 902-09-22.84. Swivel well "KMP- ..." (one pipe entered the well and one pipe came out of the well, but changed direction) - the selection is performed according to Table 2, TP 902-09-22.84. Well with one connection "KMU1- ..." (when two pipes entered the well and one pipe left the well) - the selection is performed according to table 3, TP 902-09-22.84. Well with two connections "KMU2- ..." (when three pipes entered the well and one pipe came out of the well) - the selection is carried out according to table 4, TP 902-09-22.84.
2. We decided on the table. Now we need to determine the diameter of our well (column 5)... Typical well diameter - 700mm, 1000mm, 1500mm, 2000mm. The diameter depends on the depth of the pipe tray, the number of connections, and the diameter of the pipelines. Those. in table 1, ... 4 you select the diameter of the well according to the diameters of your pipelines. But do not forget that if the chute lies more than 3.0 m (inclusive), then the minimum diameter of the well must be at least 1500 mm. Even if in a typical project for this well diameter, the pipe diameters do not match your option.
3. We choose height of the working part (this is the distance from the top of the concrete channel of the well to the bottom of the floor) - column 7. Basically, the height of the working part depends on the depth of the well. And it is selected almost entirely at the discretion of the designer. When choosing the height of the working part, several rules must be taken into account: 1) The comfortable height of the working part for servicing the well is 1800mm... 2) The height of the working part is always a multiple 300mm... 3) If the well is very deep, then the height of the working part must be selected in such a way that the neck is no more 1000mm, (because a person is not comfortable going down into a well with a high neck). 4) If the well is shallow, then when choosing the height of the working part, you must not forget that the minimum height of the neck 350mm (from design features).
4. All unknown parameters for sizing a well are defined. You can choose the brand of the sewer well according to TP 902-09-22.84.

Column 8 - value of the height of the neck. It is determined:

"Neck height" \u003d "Full depth of the well (column 4)" - "height of the tray (column 6)" - "height of the working part (column 7)".

Column 9 - shows the value of the volume of the main structures. It can be calculated according to TP 902-09-22.84. In my projects, I never spend time calculating this value. Nobody ever needed this figure. If you have time, you can count it to complete the project.

Column 10 - the height of the drop is shown. This figure is shown for a differential well (when the elevation of the supply and discharge pipelines is different).

Column 11 - shows the volume of concrete per tray. If the diameters of all pipelines in the well correspond to the selected brand of the well, then we take the volume of concrete on the tray according to tables 1 ... 4 TP902-09-22.84. For the rest of the wells, the volume of concrete per tray you will calculate manually, using knowledge of geometry.

In column 12- show the type of hatch. Depends on where the hatch is located (under the roadway or in the lawn area). We select according to TP 902-09-22.84.

In column 13 - showing the type of ladder. The brand depends on the height of the working part of the well. It is selected according to TP 902-0922.84.

Column 14- indicate the presence of waterproofing. It is required for the construction of wells in wet soils or in the presence of upper water. It is carried out with bitumen in two layers, outside and inside the well.

For private projects (private country house), the sewer well table can be expanded.

Columns 14-24 detail what the well consists of.

For projects completed in Moscow, the well table looks like this:

The table is performed according to PP16-8.

Note! The trough part is included in the height of the well. And not included: hatch, mouth and base plate.

Example 1: Well K1 (from the table) has a depth of 2320mm to the pipe chute. The hatch is 50mm above the ground. Those. the total depth of the well is 2320 + 50 \u003d 2370mm.

2370-1920-120-330 \u003d 0mm.

Example 2: Well K2 (from the table) has a depth of 2940mm to the pipe chute. The hatch is 80mm above the ground. Those. the total depth of the well is 2940 + 80 \u003d 3020mm.

The height of the well according to KK-15.20 is 2040mm (without the slab, neck and hatch). Distance from the bottom of the well to the pipe tray - 120mm (according to PP16-8).

Floor slab -120mm. Manhole structure + support plate UOP-6 - 330mm.

2040-120 \u003d 1920mm. It is also necessary to install a floor slab, an UOP-6 base plate and a hatch on top of the working part.

3020-1920-120-330 \u003d 650mm.

It remains: For the remaining 650mm we add the neck rings: K-7-5 (500mm high) + K-7-1.5 (150mm high).

Those. 650-500-150mm \u003d 0mm.

The well is assembled.

This is approximately how a sewer well is assembled according to PP16-8.

Similarly, you can assemble a well for Moscow projects according to SK2201-88, using ready-made working chambers KL-10 ... KL-20 as a working part. They have a fixed height. And a drainage tray is cast inside these chambers at the construction site. For the drain (rainwater drainage), the same standard project SK2201-88 is used, but the tray is inside working chamber ВС-10 ... ВС-20 is not cast.

I hope the article was useful for you. Happy design!
