Description

The invention relates to hydraulic engineering and can be used in the construction of protective clothing on the slopes of canals and ponds.

The purpose of the invention is to increase the efficiency of the drainage system.

In FIG. 1 shows a device for drainage of concrete-film antifiltration cladding in open form; in FIG. 2 - the same in closed form. 10

The drainage device includes an anti-filtration screen made of flexible film 1, reinforced concrete slabs 2, trenches with a drainage system 3 in the form of perforated corrugated elements made of 15 rubber cord fabric 4 and provided with a loading plate 5, drainage terminal 6, a grill with holes 7, fiberglass 8, inverse filter 9.

The device operates as follows. 20

With a high standing of groundwater or with a sharp discharge of water in the structure, excessive hydrodynamic pressure occurs, exceeding the hydrostatic pressure of the water in the channel. 25

Water, creating excess pressure, squeezes the plate 5 and penetrates through corrugated perforated elements made of rubber cord fabric 4 into the drainage system 3, passes through a grill ₃₀ with holes 7, fiberglass 8, drainage terminal 6 and enters the channel. If there are no drainage leads, then under its own weight the plate 5 is lowered, corrugated elements with perforation made of rubber cord fabric 4 are folded and, blocking all openings, prevent water filtration from the channel.

A device for drainage is as follows.

After preparing the base and arranging the trench, a flexible film 1 is laid out along the slope, then a reverse filter 9 of sand, gravel, and gravel is arranged in the trench. Drill ¹ xy place fiberglass 8, which can be in rolls or blocks, it prevents 3 particles of sand, gravel, silt from getting into the drainage system.

Then, pre-prepared corrugated elements with perforation of rubber cord fabric 4 are glued to sections of the drainage system 3, made in the form of half-Tauris, in sections 1.5-2.0 m long made of concrete, reinforced concrete, metal or hard polymer material, and glued on top to plate 5, made of metal, a polymeric material or in the form of a thin reinforced concrete slab.

On top of the drainage system 3, a grid with holes 7 is laid, which can be made of metal, and then fiberglass 8 and drainage terminal 6 is made of stone and gravel aggregate, which is arranged between reinforced concrete slabs 2 and glued together with flexible film 1 to drainage system 3.
