METHOD TO INCREASE ECOLOGICAL SAFETY OF INUNDABLE DISPOSAL AREA OF ENTERPRISE WASTES UNDER OPERATION

摘要

FIELD: construction.;SUBSTANCE: method includes arrangement of a hydraulic curtain between a disposal area and a rive in the basement. The hydraulic curtain is made as a trench of counterpressure and a water-collection drainage trench approached near the disposal area. The bottom of each trench is arranged in a water permeable layer of mostly loose deposits of the basement, and in the trenches at the specified distance from each other there are wells arranged, accordingly injection (counterpressure) and drainage ones. Each well is deepened for the specified value into a water impermeable layer of cracked rocks of the base and is hydraulically communicated with the trench. The hydraulic curtain is equipped with at least two water supply devices, one of which provides for supply of pure natural water into the counterpressure trench, and the other one - supply of captured drainage water collection trench into a system of water reuse of the enterprise. Then the water level in the counterpressure trench is maintained above the water level in the water-collection drainage trench.;EFFECT: invention prevents penetration of waste waters from the disposal area into the river, and work scope is reduced in development of a hydraulic curtain.;7 cl, 4 dwg
