SYSTEM AND METHOD FOR BLOCKING LEACHATE BY USING DIVING BACK FLOW TANK

摘要

PURPOSE: A system and a method for blocking a leachate are provided to minimize contamination of underground water area by using a diving typed drainage sink for generating a flowing direction toward the drainage sink being blocked in a containment zone. CONSTITUTION: A method for blocking a leachate is formed by: a step for installing an around barrier wall being extended to the inside of a bottom barrier layer for blocking the suspended water drainage sink being arranged under a ground water level with the bottom barrier layer; a step for mixing the leachate and the underground water in the drainage sink for forming the mixture of the leachate and the underground water having a leachate level in the drainage sink; a step for inducing the flowing direction from the around area toward the drainage direction by collecting and eliminating the mixture from the drainage sink; a step for covering the drainage sink by using a large amount of earth and sand for extending the upper unit of the earth and sand to the level higher than the underground water level; and a step for loading waste on the upper unit of the earth and sand for loading the waste for higher than the underground water level.
