They are laid out by unwinding a film roll of the fabric, starting from the bottom of the hole to the surface of the water. due to the level difference in the upper and lower pools, the film is pressed tightly against the grid.

Способ осуществл ют следующим образом .The method is carried out as follows.

В теле плотины 1 и на местности устанавливают устои 3-6.К усто м прикрепл ют канаты 8, 9 с сеткой 7 из высокопрочного гибкого материала, например капрона. Сетку 9 размещают в проране 2, в водной среде. Это сделать легко, поскольку давление потока в проране на сетку невелико из-за большой площади просветов в сетке. Верхний край сетки, т.е. канат 8, поддерживаетс An abutment 3-6 is installed in the body of the dam 1 and on the ground. Ropes 8, 9 with a mesh 7 of high-strength flexible material, for example, nylon, are attached to the mouths. The mesh 9 is placed in the proran 2, in the aquatic environment. This is easy to do, since the flow pressure in the gap on the mesh is small due to the large area of the gaps in the mesh. The top edge of the grid, i.e. rope 8, supported

поддерживаетс поплавками 16. Нижний край сетки 7 прилагают к грунту 17 основани (фиг.1). Поток из верхнего бьефа 19 течет через проран, через сетку 7 прорана в нижний бьеф 20.f 45supported by floats 16. The lower edge of the mesh 7 is applied to the ground 17 of the base (Fig. 1). The flow from the upstream 19 flows through the hole, through the mesh 7 of the hole into the downstream 20.f 45

the lower edge of the panel with a load 15 on the ground, Load 15 can be made, for example, from a polymer tube filled with sand or fine gravel. The load 15 of the panel 10, under the influence of its weight, is embedded in the applied soil 18. It is easy to lay the roll to the bottom, since the windage of the roll is small. The roll is rolled up by moving it from the bottom up, from the bottom of the hole to the float of the net 7. The unfolded part of the web 10, flowing onto the net, is pressed against the net and held, stabilized, fixed on it.

After laying on the grid 7 of the film panel 10 at one edge of the pro-hole (Fig. 2 - at the right edge), the panel 11 is laid at the other edge (left) to symmetrically load the dam in the gap. The film panel 11 is installed exactly as the panel 10, i.e. rolling the film roll from the bottom of the hole to the float 16, After installing the panel 11 set the overlap on the edge of the panel 11 (dashed line in figure 2), the sheet 12. Then, for the same reasons of symmetrical loading of the abutments 3-6, set the panel 13 at the right edge of the pro-hole, and in conclusion, establish the middle panel 14, covering it with the edges of the edges of the panels 12 and 13 (dashed lines on the right and left in the image of the panel 14 in Fig.Z).

The dam 1 with the closed aperture 2 is shown in Fig. 3, 4. On the grid 7 there are film panels securely pressed to the grid by the pressure of water 19 in the upper pool due to the excess of the levels by the amount of H with the lower pool 20.

In this way, it is possible not only to overlap the cut, but also to influence a water filling dam made of polymer materials.

they are coated on the side of the incoming water flow with a film in the form of vertical panels with a load on the lower edge of each panel, and laying the sheet on the net by rolling the film roll, moving it from the bottom to the surface of the reservoir, while laying the sheets in the direction from the edge is cut through to its middle with overlapping overlap of the joint between adjacent panels.
