System for seepage detection of anti-seepage layer

Abstract

The invention provides a system for seepage detection of an anti-seepage layer. The system includes a conductive grid and a monitoring detection device, the conductive grid is laid under the anti-seepage layer and includes a first lead group and a second lead group which are arranged according to preset rules, any lead in the first lead group and any lead in the second lead group intersect and have an intersection point, grid points in the conductive grid are formed in lead intersection positions, and two leads at each grid point are arranged in an insulated manner; and the monitoring detection device is used for providing a source signal for each loop formed by any lead in the first lead group and any lead in the second lead group, collecting effective electrical signals in each loop, and based on the electrical signals in each loop which are collected at different moments, determining whether seepage occurs in the anti-seepage layer at the intersection position of two leads in each loop and nearby. Through the detection system provided by the invention, whether seepage of the anti-seepage occurs can be effectively detected, seepage positions can be located, and a seepage pollution scope can be monitored.

Description

technical field [0001] The invention relates to anti-seepage layer technology, in particular to an anti-seepage layer leakage detection system. 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 the soil and ground...

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
