3. The device according to PP.1 and 2, characterized in that it is provided with a stove laid at the bottom of the selenos bed, and the grooves are installed on the stove.

4. Device on PP. 1-3, characterized in that it

The invention relates to hydraulic engineering, in particular, to seed protection devices, and can be used on selenosny river beds and dry valley to protect their bottom and banks from processing.

The purpose of the invention is to increase the efficiency of quenching the mudflow energy.

FIG. 1 shows a tray of an anti-tipping device, general view; in fig. 2 shows section A-A in FIG. 1 in FIG. 3 shows a section BB in FIG. one; in fig. 4 - anti-drip device, view from the downstream; in fig. 5 shows a section B-B in FIG. one; in fig. 6 — node I in FIG. one; in fig. 7 - section G-Y in FIG. 6; in fig. 8 - anti-settlement device with curvilinear grooves and inclined front walls, view from the downstream; in fig. 9 is the same plan} in FIG. 10- tray.

The anti-settlement device contains a tray 1 with openings 2, mated with the upper edge 3 to the bottom A of the seleniferous bed 5. The side walls 6 of the tray 1 are adjacent to the banks 7 of the bed 5 in the upper part 8 of the tray 1.

Tray 1 is formed in the form of longitudinal tapered gutters 9 with inclined side walls 10.

The anti-settlement device can be provided with a plate 11, inclined front walls 12, and equipped with a nano-catcher ditch located in the downstream.

5. Device on PP. 1-3, characterized in that the gutters are made of ribbed plates, and the holes are located between the ribs.

6. The device according to paragraphs. 1-3, characterized in that the channels are made in the form of lattices.

7. The device according to paragraphs. 1-3, 5 and 6, characterized in that the axes of the grooves are directed at an angle to the direction of the selenos bed.

The grooves 9 are made of ribbed plates 14 with openings 2 located between the ribs 15, or of the grids 16. The edges 17 of the grooves 9 are reinforced, for example, with corner elements 18.

In contact and fastened between

are the faces of the adjacent inclined side walls 10 of the grooves 9 form ribs 19, which serve as selenium, and between the inclined side walls 10 - the cavity 20. To the side walls 6,

adjacent to the shores 7, adjacent protective screens 21, preventing the erosion of the shores 7.

The device works as follows.

in a way.

The debris flow as it moves along the chute 1 is divided by the chutes into sleeves, and the water contained therein is drained through holes 2 into the cavity 20. The discharge of water, which is a lubricant for the rock mass, caused by the mudflow, causes thickening, braking and stopping mudflow, i.e. to quenching the mudflow energy, which also occurs when the flow is divided into chutes. An increase in the friction against the walls of the grooves and a decrease in the angle between the lateral walls

10 walls of grooves 9

as in this case, the hearth mass contained in the mudflow is squeezed up.

A high power flow can overcome several anti-mudflow devices cascaded in the selenous bed 5. At the same time, part of the stream passing through the anti-mudflow device enters the nano-collecting ditch 13, the fall of the rock mass into the ditch 13 is accompanied by its crushing, resulting in erodating ability After the passage through the anti-mudflow device, the mudflow decreases sharply, i.e., the replenishment intensity of the stream during its movement by the new mudflow material decreases markedly.

As the anti-seam devices are overcome, less and less rock mass remains in the stream, and water

bassily dumped down the channel 5, ahead of the mountain mass.

With the wave-like nature of the mudflow, separate stones, 5 drawn by the flow, having a shape close to spherical, in trenches 9 move towards the flow and, interacting with the next wave, have a braking effect on the flow.

The axes of the grooves 9 can be directed parallel to the direction of the mudflow or at an angle to it. Particularly efficiently positioning the anti-mudflow device at an angle to the direction of the mudflow in the sections of the channel turn, in this case, the energy-absorbing effect increases sharply and the eroding effect flow to shore decreases.
