Abstract

Usage: the invention allows to achieve when creating a freshwater zone in a reservoir of salt water. Essence: a section of striking freshwater keys is separated from the salt water body by a section of a partition, which, in the form of a section, is set further along the coastline. A channel of a freshwater coastal zone is formed. Fresh water from section 6 of freshwater springs flows through the canal, displaces salt water and carries it into the water area. we’ll get it. In the plots - the water is fresh. 1 s.p. f-ly, 2 ill.

Description

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 creating a freshwater zone in the form of a freshwater coastal section of the reservoir upon receipt of fresh water from the area of the breaking freshwater springs located within the freshwater zone.

In FIG. 1 shows a body of water with a freshwater zone and a section of beating freshwater keys in it. plan view; figure 2 is a section aa in figure 1, side view.

In Fig. 1.2, the following notation is accepted:

1 - coastline of a reservoir; 2 - bedrock in a reservoir; 3 - alluvial soil in a reservoir; 4 - water body of the reservoir; 5 - coastal area of the freshwater zone; 6 - plot of beating freshwater keys in a pond; 7 - a section of a partition separating a section of keys from the water area of a reservoir; 8 - a septum section separating the coastal section of the freshwater zone from the water body of the reservoir; 9 - the end of the partition, located in the water area of the reservoir; 10 - tubular baffle float; 11 - wall of the partition from the panels of the polymer film suspended from the tubular floats; 12 - tubular load at the lower end of the panels of the polymer film; Ah- excess of the level of fresh water over the level of salt water in a reservoir; BC - the borders of section 7 of the partition; SD - the boundaries of section 8 of the partition.

The method is carried out as follows.

The location of the 6 striking freshwater springs in the pond is determined. The sizes and boundaries of the coastal section 5 of the freshwater zone are determined. Elements of the partition are made separating sections 5 and 6 from the water area 4 of the reservoir. The elements of the partition are made in the form of panels 11 of a polymer film suspended from a tubular float 10, the lower edge of the panels is attached (attached) to the tubular weights 12. The floats 10 can be made of polymer, plastic pipes with a plug |

neck ends. The weights 12 can be made of polymer pipes of small diameter, filled with heavy bulk material, for example, fine gravel, sand, etc. The edges of the panels should be equipped with a quick disconnect connection, for example, zipper snakes.

The septum elements are delivered to the reservoir. Mount section 7 of the partition length of the aircraft. For this purpose, from a floating means, for example, a self-propelled or towed barge, the elements of the partition are swept, connected with zippers of the cloth of the partition to a single partition in the aircraft section. In this case, the load 12 is introduced into the alluvial soil 3, a tubular float pops up 10. The height of the septum is formed so that it rises above the level of salt water in the water area 4 of the reservoir by Ah, which should be no less than the density head of fresh and salt water. Then mount the section of the SD partition. The end of the 9 partition is located in the water area 4 of the reservoir outside the desalinated coastal zone 5.

Fresh water, all the time coming from the keys of section b, fills the fenced off from the water area 4 reservoir 7

the part of the reservoir where the keys are located. The water level in this part of the reservoir rises above the water level in the water area 4. Due to the difference in levels, fresh water flows into the coastal section 5, flows through this section, which takes the form of a channel bounded on the right by coastline 1, and on the left by partition 8. The fresh water of the keys to section B is mixed with salt and

on the site 5 flows into the water area 4, the bend end 9 of the partition. Over time, due to the continuous flow of fresh water from the keys of section b, the salinity of the stream in section 5 decreases, and decreases.

finally, the whole stream becomes fresh. Fresh iodine from channel 5 enters the water area 4 of the reservoir. Since the area of the salt water mirror and the volume occupied by it became steel after the installation of the partition 7-8,

smaller than the original, limited by the coastline 1 of the reservoir, the salinity of the water in area 4 becomes higher than the original.

The coastal section 5 is used to house hydraulic structures whose operating conditions, the reliability and durability of which in the fresh water of section 5 are significantly improved.
