If you are thinking about the depthBury the sewer pipe, then first you need to familiarize yourself with the technology of the work. It is also important to choose the right building materials, since this will depend on 50 percent of the success.
In order for the sewerage to cope withtasks assigned to it as efficiently as possible, it is necessary to follow the technique of laying pipes on the site. To arrange an external system, it is recommended to use polymeric smooth elements, which differ in orange color. If the depth of installation is considerable and the pipes are subjected to dynamic loading, it is recommended to choose corrugated double-layer structures made of PE or PP.
This is true for those cases when the systemsewerage passes under automobile and pedestrian roads. Pairing of polymer pipes is carried out with the help of shaped products according to the type of bends, couplings, and also adapters.
At work, you must use SNiP.Sewage, according to these rules, is stacked using pipes with a diameter of 110 millimeters. If the products have an orange color, then this just indicates their purpose, that is, they can be laid outside the buildings, in addition, they are more durable and durable in comparison with products of gray color. The latter are used in the arrangement of internal systems.
Pipes for external drainage are not exposedcorrosion, all sorts of damage and when installed with the right slope do not form blockages due to the internal walls, which are distinguished by their smoothness. The permissible depth of laying of similar products is 3 meters.
When carrying out the described work, you shouldto use SNiP. Sewage at the same time will last a long time. First you need to prepare trenches. You can do this manually using a shovel or by renting an excavator. The depth of the trenches to be made will depend on the freezing line of the soil in a certain locality. According to SNiP, the depth of installation of sewer pipes is 0.5 m lower than the level of the freezing point of the soil. These parameters are approximately 3.5 meters for the northern regions of Russia. As for the middle band, this indicator varies from 2.5 to 3 meters. On the Black Sea coast, it ranges from 1.25 to 2 m. These figures are not categorical, they can be changed within certain limits. This will affect the features of the terrain and the line of occurrence of groundwater.
However,be carried out at a distance of 0.5 m from the ground, which is the minimum limit. If in the work it is supposed to use pipes with a diameter of 110 millimeters, in the ground it is necessary to prepare grooves with a width of 0.6 m, while the depth should be 0.05 m more than the depth of the pipe laying.
Sewerage must be laidonly after the trench is dug. It has special requirements. The bottom must be leveled, and a certain slope must be created, which should be equal to 2 centimeters per running meter of the pipeline. The construction of sewerage involves careful alignment and ramming of the soil. Further, the preparation of gravel and sand, the thickness of which should be equal to 15 cm, is laid.
The pillow must be compacted.The site should be located two meters from the manhole. Among other things, when choosing an arrangement, it is necessary to approach the junction point of the pipeline and the inlet pipe. In those places where there are sockets in the sewer system, small pits should be made.
After you became aware of whatdepth to dig in the sewer pipe, it is possible to produce all subsequent work. Once you have reached the stage of laying the pipeline, you need to start the following manipulations. It is recommended to start from the foundation of the building. Pipes should be shoved down into pre-prepared trenches. To mate the two products, the bell of the first element and the smooth end of the other must be cleaned of dirt. The mating points should be treated with special compounds. The pipe must be inserted into the socket. This technology should be followed when the remaining elements of the system will be combined. When pairing parts of the pipeline, one piece must be inserted into the socket of the next one. In order for the pairing data to be reliable, it is necessary to measure the depth at which one tube will enter the other. The appropriate place will need to be noted.
If you know what depth to dig insewage pipe, it will greatly simplify the work. If there is a conclusion in the foundation of construction, the socket of the external sewage system must be brought to it. If there is not one, you should make a hole. When fecal sewer is arranged, it is recommended to use diamond drills that will do their job well. In order to ensure a turn, it is necessary to apply special bends at 15, 30 or 45 degrees. If the sewage pipe has a length that exceeds 15 meters, a revision should be mounted in such areas.
If you are interested in the question of whichdepth to dig in a sewer pipe, then you can read about it above. But after stacking the products, you need to analyze the angle of inclination. If all the manipulations were carried out correctly, then you can proceed to the backfill of the system. To do this, it is recommended to apply the soil that was formed when excavating a trench, but in this case all large and sharp stones, as well as extraneous elements, should be removed from it. Specialists recommend breaking sufficiently dense blocks that may be present in the ground so that they do not crush the product.
