ON

The invention relates to hydraulic engineering and is intended to alter the ecological status of a body of water.

The purpose of the invention is to increase the efficiency of the method by eliminating the mixing of layers of fresh and salt water in a pond and improving the accuracy of fixing the boundary between these layers.

In FIG. 1 shows a device with a coating in a pond, before supplying fresh water, side view, section; in FIG. 2 - the same, after the formation in the pond of a layer of fresh water of intermediate thickness, side view, section; in FIG. 3 - the same, when a layer of fresh water reaches the calculated thickness, side view, section.

The device consists of a partition 1 with a culvert 2, separating the pond 3 from the water area 4. On the surface of the salt water in the pond 3 (Fig. 1) there is a coating 5, which consists of interconnected mats b and 7. Each mat consists of filled fresh water in polymer containers of 8–10 with a cloth soldered to them. 11 polymer film. The extreme containers of the mats are equipped with cable-bucket devices, each of which is made in the form of an air-filled container 12 of elastic-flexible material (like a baby balloon) and a cable 13 of kapron threads. Number 14 indicates the connection of mats b and 7; At - the depth of salt water in the water area; Hc is the thickness of the salt water layer in the pond; Np is the thickness of the fresh water layer in the pond; AN is the difference in levels in a water body and water area equal to the difference in density heads.

The proposed method and device is used as follows.

Separate the pond 3 from the water area 4 by a partition 1 with a culvert opening 2. On the surface of the salt water 3 of the pond, before supplying fresh water to the pond, place a coating 5 (Fig. 1), which consists of mats 6 and 7 connected by connection 14 for example in the form of a zipper on the film edges. Each mat 6,7 consists of polymer containers 8-10 filled with fresh water with a polymer sheet soldered to them 11. Separate containers (extreme containers 8 and 10) are equipped with a cable buoy device 12, 13 on the upper side. The buoy is made in the form of an air-filled container 12 isoup-flexible material (a children's balloon can serve as a great image). The rope 13 buoy is made of kapron threads. The cable length 13 is assumed to be equal to the estimated thickness of the fresh water layer in the pond.

Cover the surface of the water in the pond with coating 5. If there is a threat of crush (bending of the coating), then between the longitudinal containers 8-10 in the transverse direction

spacer containers (not shown in Figs. 1-3), also made in the form of polymer containers filled with fresh water, are inserted into the mat. Coating 5 floats on the surface of salt water 3 (Fig. 1) in a pond,

since the density of the mat is less than the density of salt water, because the film walls of containers 8-10 and the film of the cloth 11 are lightweight, and the water in containers 8-10 is fresh, i.e. its density is less than the density of salt water

5 (Fig. 1). Air-filled containers 12 lie on mats 6.7, cables 13 are weakened.

On the coating 5 serves (poured) fresh water. It is poured over coating 5 and accumulates on the coating with a layer of thickness Hn (Fig. 2); a layer of fresh water rises above a layer of salt water, squeezes out excess salt water through a culvert 2 from tank 3 to water 4. Air-filled tanks 12 float

5 on the surface of fresh water, cables 13 hang in a layer of fresh water (Fig. 2).

After a certain amount of time has elapsed, a sufficient amount of fresh water accumulates in the pond to form a layer

0 calculated thickness Np. This layer is fixed by the length of the cables 13, because ropes 13 Floating Air-filled containers 12 (Fig. 3) have two properties: they show that the layer of fresh water reaches the calculated thickness Нп; they are kept afloat, at the boundary between the layers of salt water Нс and fresh water Нн a coating in the form of mats 6.7. In this case, the coating acquires a new property. It becomes a gasket between the layers of salt and fresh water. Therefore, it is called a coating-gasket. The coating layer clearly separates the layers of water in the pond. The position of the coating is strictly

5 is fixed at the calculated thickness Нп of the fresh water layer. Thanks to this, the chain of the invention has been achieved.
