Abstract

A METHOD FOR UNDERWATER DUMPING, which includes dumping soils of dredging sea canals into a dump on a submerged slope, characterized in that, in order to protect the environment and ensure the possibility of receiving a feeding shell, slope on the magnitude of the penetration of the wave effect into the soil and form containers on it, then dredging soils containing impurity shell are poured into the indicated containers and after flushes the impurities are rakuschki extraction.

Description

00 4 F

The invention relates to mining and can be used in hydraulic construction and agriculture.

The purpose of the invention is to protect the environment and to ensure the possibility of obtaining a forage shell at the same time.

The removal of the shell from the coastal zone impairs the stability of the shores and activates abrasion processes; the selection of shells from sea tangs and islands alters the flow pattern, which worsens the living conditions of living organisms in the sea.

In this connection, careers in the Sea of Azov are now almost completely banned.

In the dredging soils on the sea canals there is a significant amount of shellfish, the content of which reaches 40% and more of the total volume of the developed soils. Dredging soils are mainly discharged to underwater and coastal dumps.

At the same time, the shell contained in these soils can be used as fodder for the needs of agriculture after its purification from other fractions (silt, sand, clay, pebbles, etc.).

In the invention, the preparation of the forage shell from the dredging soil is carried out by washing the impurities (silt, clay, sand) with waves and current. This effect is achieved in dumps, organized by dredging the bottom within the waters of landfills dumps located in the coastal zone of the sea, by the amount of wave penetration (the active layer).

The execution of the work is carried out in the following order.

Before dredging works on the sea channels, the underwater welding water area is over-deepened with respect to the adjacent underwater slope by the amount of wave action penetrating the ground. This value is determined by calculation or special studies for each particular site. Dredging soils on the sea channel, containing shell, are poured into the formed bottom container. In the stormy period, the shell is washed out and is formed in the dump. Later dump used as a quarry for the extraction of shells. The operation is then repeated in the newly released dump container.

The invention provides a significant economic effect.
