Leak detection method of anti-seepage layer

Abstract

The invention provides a leakage detection method of an anti-seepage layer. The method includes laying a conductive grid under the anti-seepage layer, wherein the conductive grid includes a first wire group and a second wire group arranged according to preset rules, and any wire in the first wire group is compatible with Any wire in the second wire group crosses and has a crossing point, each wire crossing forms each grid point in the conductive grid, and the two wires at each grid point are insulated; Each loop composed of any wire in the first wire group and any wire in the second wire group provides source signals, and collects effective electrical signals in each loop respectively; based on the electrical signals in each loop collected at different times, determine Whether there is leakage in the anti-seepage layer at the intersection of the two wires in each circuit. The detection method provided by the invention can effectively detect whether leakage occurs in the anti-seepage layer, locate the leakage position, and monitor the leakage pollution range.

Description

technical field [0001] The invention relates to an anti-seepage layer detection technology, in particular to a leakage detection method of an anti-seepage layer. Background technique [0002] With the rapid economic growth, the amount of solid waste generated in my country is increasing. In 2010, the amount of domestic waste cleared and transported exceeded 150 million tons, and the amount of industrial hazardous waste generated was 14.29 million tons. The amount of hazardous waste stored over the years has reached 100 million tons. The potential danger of the generated solid wastes polluting the environment cannot be ignored. Landfill disposal is the final disposal method of solid waste. When landfilling waste, in order to prevent secondary pollution to groundwater, soil, etc., it is necessary to lay artificial anti-seepage lining in the landfill to isolate the inside and outside of the landfill and prevent the pollutants in the landfill from seepage. The filtrate enters t...

AI Technical Summary

Problems solved by technology

At present, the existing anti-seepage layer leakage detection technology cannot be widely popularized and applied due to cost reasons.

[0003] On the other hand, large-scale industrial evaporation ponds, slag storage yards and industrial liquid storage tanks also urgently need to solve the problem of leakage detection of HDPE membranes in the anti-seepage layer from the perspective of their environmental sensitivity and corporate benefits
