Abstract

The invention relates to the field of hydraulic engineering and can be applied in the construction of protective mounts and impervious clothing slope slopes. The purpose of the invention is to improve the operational reliability and filtration efficiency. The drainage element of the drainage system is made in the form of a hollow cylinder with a valve in the form of a ball 4 placed inside. The hollow cylinder is equipped with non-freezing walls and filter bases. The groundwater affects the valve, opening the way for water to enter the structure through the filter tank 6. If the hydrostatic pressure in the structure is above the groundwater level, then the water column is pressed against the valve. It tightly closes the hole in the rubber insert 5, preventing water from leaking out. 1 hp f-ly, 3 ill.

The invention relates to hydraulic construction and can be applied in the construction of protective mounts and impervious clothing slope slopes.

The purpose of the invention is to increase operational reliability and improve filtration efficiency.

Figure 1 shows the finished block drainage device; Fig. 2 shows a reinforced concrete slab with a hole in it prepared to accommodate a drainage system in the form of a block, a section; on fig.Z - a reinforced concrete plate, a section.

The device for draining the concrete film liner includes reinforced concrete slabs 1 with an opening for the drainage block, a gasket 2 of roofing material, a film panel 3, a valve 4 in the form of a ball, a rubber insert 5, filtering blocks 6 made of coarse-grained porous concrete, insulation (poro - isol) 7, shell 8 from non-freezing liquid, gravel backfill 9.

During installation of the device for drainage of the concrete-film cladding, the film sheet is rolled up and glued to the side face of the slab, coated with mastic. The drain unit is lowered and glued simultaneously.

The device works as follows.

With a high standing of groundwater or a sharp discharge of water in the structure during the winter thaw and spring flood pressure

groundwater acts on the valve 4, made in the form of a ball, lifting it up, thus opening the way for water to enter the structure through the filtering unit 6. Poroisol 7 and shell 8 of antifreeze liquid are arranged to prevent water from freezing in the drainage system to freezing depth ground.

In the case when the hydrostatic pressure in the structure is higher than the ground flow pressure, a water column presses on the ball-shaped valve 4, and it tightly closes the opening in the rubber insert 5, preventing water from leaking out of the channel. Depending on the depth of soil freezing, the depth of the drain is selected.
