Abstract

The invention relates to hydraulic engineering associated with the regulation of water quality in water bodies, in particular saline, and the creation of fresh water reservoirs on the basis of these water bodies. The purpose of the invention is to increase the efficiency of work by ensuring the protection of the reservoir from saline wastewater and drainage water. At the bottom of the desalination reservoir, a system of interconnected artificial cavities is created, which are distributed depending on the degree of permeability and salinity of the soils composing the bottom of the reservoir. In this case, the bottom of the grooves arranged at different levels. The notches with the greatest depths are located along the coastline, along which an annular or open channel is created inside the reservoir, which is connected to the deepest notches. In addition, at the location of the concentrated release of saline water into the reservoir, a recess is created, which is connected to the deepest recess either directly or through intermediate recesses. 1 il.

Description

The invention relates to hydraulic engineering related to the regulation of water quality in reservoirs, in particular saline, and the creation of fresh water reservoirs on the basis of these reservoirs.

The purpose of the invention is to increase the efficiency of work by ensuring the protection of the reservoir from saline wastewater and drainage water.

The drawing shows a scheme for preparing a reservoir bed for desalination, which explains the proposed method.

The scheme includes areas of sandy 1, silt-sandy 2 and muddy 3 beds of the reservoir, concentrated surface and bottom 5 sources of saline water, artificial excavations 6 in the bottom of the reservoir, artificial excavation 7 with the greatest depth, channels 8, which discharge salt water from the soils, composing the bottom of the reservoir, as well as interconnecting artificial excavations, along the coastal channel 9 for intercepting saline drainage water and diverting 10 saline water out of the reservoir.

Example. For mapping of the bottom, topographic and hydrological surveys in the water area and in the territory adjacent to it should be preceded with indication of the soils composing the bottom of the water body and their degree of salinity, as well as the location of surface and bottom concentrated sources of saline water entering the water body.

Next, near the coastline in the reservoir bed, a recess 7 is created with the greatest depth, which is connected to a device for diverting 10 saline water out of the reservoir,

At the locations of concentrated surface k and bottom 5 sources of saline water, the grooves 6 are created, which are connected to the deepest notch 7 either directly or through intermediate ones. 6 given points of the bottom of the reservoir, depending on the composition of the soil and its mineralization (sections 1-3), create I deep-pit excavations 6, which interconnect some of them with the deepest excavation 7 through channels 8. At the same time, the soil from artificially designed excavations can to be laid in the excavations made before desalination, the location, shape and size of which do not satisfy the accepted desalination scheme of the given body of water.

At the bottom of the reservoir create a system of channels 8, collecting in the recess 6 salt water from the periphery. - At a given section of the coastline in the reservoir, a channel 9 is created for intercepting saline drainage water and connecting it with a notch 7

In the process of desalination of the reservoir and during its subsequent operation, the recording of channels and channels is periodically checked, and, if necessary, they are cleaned and deepened. This is especially important if there are constantly active concentrated sources of saline water in the reservoir.

Using the proposed method of preparing a pond bed for desalination will increase the efficiency of the reservoir desalination and ensure

its shield from the mineralized waste and drainage waters not only during the desalination process, but also during the operational period.

Invention Formula The method of preparation of the desalinated reservoir bed, including hydrogeological and hydrochemical studies of the reservoir bed and adjacent territories, as well as laying connecting channels in the bottom of the reservoir to drain salt water from the natural low sections of the reservoir floor to the recesses adjacent to the blocking structures, performed before the process of removing salt water from a reservoir, characterized in that, in order to increase the efficiency of work by ensuring the protection of the reservoir from the mineralized waste and drainage After hydrogeological and hydrochemical studies, the bed of the reservoir and the adjacent areas simultaneously with connecting, diverting salt water channels create artificial cavities to localize the saline water at places of entry from surface and bottom sources, and arrange an annular or open channel along the coastline of the reservoir to intercept drainage mineralized water, with the entire surface of the bed of the reservoir divided into zones according to varying degrees of permeability and salinity and the soils of the bed of the reservoir and in the areas of the bed of the reservoir with low-permeable soils, the number of artificial cavities is increased to equalize the intensity of removal of salt water from the surface layers of the bottom sediments of the bed of the reservoir.
