The goal is to reduce the spread of contaminants by redistributing the flow of water supplied in the reservoir. The water supply system comprises a pipeline 9 for supplying water, made along the length of the outlets and connected to a flexible bridge 11, in turn connected to ballast 12 and a float 13, and separating a portion of the hydromechanized works from the water supporting structure. The pipe 9 can be installed upwards, while it is placed with a gap in the rings connected to the flexible jumper 11, and secured by clamps 15 on the float 13, which are installed on it with a gap.

Pipeline 9 can be installed upwards, while it is placed with a gap in the rings, the invention relates to water supply and concerns the constructive implementation of the water supply system of a hydromechanized section of work carried out in a reservoir with a water supporting structure.

The goal is to reduce the spread of contaminants by redistributing the flow of water supplied in the reservoir.

Spanning device 6. To increase the length of the transit flow and, accordingly, the time of water settling in the reservoir C, a dam 8o is constructed. Requirements for water flow for process needs, as well as to compensate for natural filtration losses through the water supporting structure and evaporation are satisfied by supplying fresh water from the channel-branch channel 2 to the section of hydro-mechanized works with the water supply system.

The water supply system comprises a pipeline 9 for supplying water, made with outlets 10 along the separating portion of the hydro-mechanized works from the water supporting structure 3 of the flexible web 11, to which it is attached, and which is connected to the ends with ballast 12 and float 13o.

The pipeline 9 for supplying water can be installed by the outlets 10 downwards with a gap in the rings connected to the flexible bridge 11 and fixed with a gap to the float 13 by means of clamps 15.

To increase the stability of the float 13, it is provided with ribs 16 mounted at the waterline level. The gap between the float 13 and the pipeline 6, as well as the rigid connection of the latter, is ensured by the bolts 17. The float TK can be made of separate elements interconnected by metal straps 18.

With a steady water level in both zones of the reservoir, the bend 11 is flexible in an upright position. At the same time, the water entering through the pipeline 9 through the outlets 10 is evenly distributed over both zones of the reservoir.

If there is a significant difference in water consumption in the separated areas of the reservoir, the outlets can be shifted relative to the vertical position of the flexible lintel so that the ratios of discharge areas from both zones are equal to the water consumption in them. To ensure uniform distribution of water flow along the length of the pipeline, the size of the outflows from pump 19 should be increased in proportion to the pressure drop.

With an increase in water consumption in one of the zones of the reservoir, the water level in it decreases and the float 13 due to the formation of a certain pressure from the side of the adjacent zone moves to the zone with increased water flow. As a result of the float 13 moving, the bridge 11 deviates from the vertical position, the rings 14 rotate around the pipeline 9 and the outlet area in the pipeline from the low water level zone increases until the balance between flow and water consumption in both zones is established. As a result, the water levels in the divided zones are equalized, and under the action of gravity of the web, the float returns to its original position.

Pipeline 9 for supplying water can be installed with the outlet facing up and placed in the connection unit with the ballast and an additional flexible jumper 19 having an additional float 20.

Such constructive implementation is advisable to use to separate the working area of the reservoir contaminated with a large number of suspensions. With an equal water level in both zones of the reservoir, water enters them in the same amount. With a decrease in the water level in one of the zones of the reservoir, the float bordering it deviates in its direction, thereby increasing the height of the discharge threshold and the flow rate of the incoming water. At the same time, water discharge to the opposite zone of the reservoir is proportionally reduced up to its complete cessation. After restoring the lowered water level in the first zone of the reservoir, the water supply is again leveled.

automatically adjusted using known devices depending on the water level in the pond or its zones and the magnitude of water consumption.

The float can be made of coarse timber, and as straps - hook and chain pieces. Rocks (stones) can be used as ballast. However, to simplify installation, it is more convenient to use cable, chain, or pipe lengths as ballast. Bending the jumper can be made of pieces of web, the length of which must be at least the maximum depth of the reservoir. The long sides of the pieces of fabric are overlapped with each other, for example, with lacing or waterproof glue, and the two short sides are attached to the floats and the ballast. For the supply of water in the reservoir use pumps of famous brands. The pipeline for supplying water to the reservoir can be made of metal, and in the reservoir - as a rubber sleeve, with discharges along its length. With considerable weight, the latter can be used as a ballast.

The installation of the lintel can be carried out before the landfill is flooded in the target area, on the coast, with its subsequent installation in the reservoir with the help of mining equipment or on the water with delivery of separate sections by boat. The target intended for the installation of a jumper, before flooding the landfill, must be planned with a bulldozer.
