SU1715943A1 - Method of forming soil warehouse in water body and device therefor - Google Patents

Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to increase the efficiency of the formation of a soil warehouse in a reservoir by ensuring the continuity of the process of erecting a fence and excavating the alluvial soil from the cavity of the warehouse. A device for the formation of a groundwater storage in a reservoir includes floating equipment with a working unit placed on it, made in the form of a working chamber and connected to it is a suction slurry line, a pressure slurry pipeline and a pressure air duct pipeline. The working unit, in addition, is equipped with an additional pressure slurry pipe and an additional chamber connected by pipes with a slurry pipeline and air duct. In carrying out the method along the boundaries of the warehouse, the supporting heels are installed, the film-free container from the water is rolled into rolls at the boundaries of the warehouse. A portion of the film is embedded in the alluvial primer. After filling the part of the film located above the deposited soil, the excavated soil is removed and removed by the working unit. The filling of the film tank with water is carried out continuously during the excavation process. 2 hp ff, 9 ill.

Claims (2)

Claim 1. The method of formation of a soil warehouse in a reservoir, including a breakdown of the boundaries of a warehouse in a reservoir, the construction of fences, excavation and removal of alluvial soil from the cavity of the warehouse, characterized in that, in order to increase the efficiency of formation of a soil warehouse in a reservoir by ensuring the continuity of the process of erecting a fence and excavation of applied soil from the cavity of the warehouse, the fence is erected in the form of a film container fixed on the supporting piles, which is filled with water, for which, along the borders of the warehouse, "support piles are installed, vobodnuyu water film container is rolled into rolls of the two-layer film roll is lowered onto the bottom of the reservoir, the rolls are laid out on the boundaries of a warehouse around its perimeter, the lower edge of each roll is fixed on the end effector trenchless; stacker of film screens, with this working body they introduce part of the film from the roll into the applied soil, fill the parts of the film placed above the applied soil with water, attach the upper part of the tank filled with water to the support piles, then excavate and remove the applied soil with a working unit, and replenishing the film container water is produced continuously throughout the entire time of excavation of the applied soil from the cavity of the warehouse, 2. A device for the formation of a soil warehouse in a reservoir, including a floating means with a working unit placed on it, made in the form of a working chamber and a suction slurry pipe, a pressure slurry pipe and a pressure air pipe connected to it, characterized in that the working body is equipped with an additional pressure slurry pipe and an additional chamber connected to the suction slurry pipe - the suction pipe, with pressure pulp pipes - pressure pipes, with a pressure air pipe the house with an air supply pipe, while one pressure pulp line is connected to the bottom of each chamber, the other to the lid of each chamber, and each pipe is equipped with a locking device, and all locking devices are combined into a control system associated with a single panel.
