Now it is fashionable to pave the paths near the house either with asph alt or with special tiles. When it rains, the water partly drains and partly soaks into the ground. But on paved or other paved paths, she simply has nowhere to go. The same can happen if the soil is clayey. In addition, water, flowing from the roof, breaks asph alt or any other coating, flows onto the foundation of the building and slowly erodes it. Storm sewage is designed to solve the problem of removing rain and melt water and diverting it to the place of discharge. Depending on the terrain, buildings, the amount of precipitation, the technology of its construction is selected.
Elements of the storm sewer device
The storm sewer of a country house consists of storm water inlets that drain water flowing from the roof to the weir, trays, pipes and manholes. Usually, the most acceptable options in terms of monetary costs are selected. In addition, so that the storm drain does not become clogged, protective gratings and sand traps are provided.
Installation of storm water inlets
Gutters are installed in placesaccumulations of water. These can be places under drainpipes, in parking lots, on footpaths and in other places where it can drain. Sand and eroded soil accumulate in storm water inlets. This prevents clogging of the entire system. To prevent debris and leaves from getting into the storm water inlets, they are covered with bars from above. And yet they still need to be cleaned from time to time. If you do storm sewerage with your own hands, then to install storm water inlets, you will have to punch holes in the ceiling, and install the storm water inlets themselves on a layer of bitumen mastic.
Storm sewer installation
There is SNiP, storm sewers, regardless of who will design and install it, a specialized organization or with their own hands, it must comply with the building codes of this SNiP. The water collected in the storm water inlet flows through pipes to the collector or spillway point. If drainage is performed on the site, then it also discharges water into the collector. Storm sewage can be made of PVC pipes with a diameter of 110 mm. They are installed at a slope so that the water flows away by gravity. The slope must be maintained at a rate of 1 cm per 1 m of pipe. Stormwater pipes are buried to a depth below the freezing level of the soil. You can not bury the pipes deep, but then they will have to be insulated to avoid the formation of ice plugs. When installing the system with your own hands, it is necessary to trace the territory, that is, to determine all the lines of pipes, the installation sites of trays and wells, and then proceed to the direct construction of a storm drain. By marking withtaking into account the depth of freezing of the soil, it is necessary to dig holes and trenches, then a sand cushion is arranged in the trenches and grooves, after which all elements of the storm drain are laid, all necessary connections are made with water discharge and a well. Then all elements are closed and gratings are installed.
Installation of manholes
Inspection wells are installed at pipe bends and on straight sections, one for every 25 m of length. With the help of manholes, the system can be inspected and cleaned. Previously, such wells were laid out of brick or arranged using concrete rings. Today you can purchase and install a plastic manhole. It has many advantages over older designs: it is sealed, corrosion resistant, durable, quick and easy to install, and light in weight.
Maintenance
Usually properly designed and properly installed storm sewers last a long time. Grids need to be cleaned periodically. But it happens that blockages occur in the system, and then it is necessary to carry out a hydrodynamic cleaning of the sewer. This is done using special settings. Under the pressure of water, the blockage is removed, and the pipes are washed.
