Rapid leakage detection method for geomembrane

Abstract

The invention discloses a rapid leakage detection method for a geomembrane. The rapid leakage detection method adopts a detector (1), a buoy (2) and wires (3) and utilizes insulativity of the geomembrane and conductivity of a solution; the detector (1) utilizes a working power supply of the detector (1) to apply an electric field to a detected object; the wires (3) take charge of constructing a circuit network and transmitting an electric signal; by electrical detection, leakage is judged. By adopting the method disclosed by the invention, real-time leakage monitoring on the operating process of different anti-seepage places can be realized; the rapid leakage detection method takes effects in leak-prevention quality maintenance and monitoring of a solution tank and a landfill.

Description

technical field [0001] The invention relates to a geomembrane leakage detection technology, in particular to a geomembrane rapid leakage detection method. Background technique [0002] Existing geomembrane leakage detection methods, such as electrode method, water gun method, dipole method, etc., mainly use high-voltage electricity to apply a high-voltage electric field on the planar geomembrane anti-seepage structure, which consumes a lot of energy (needs generators and transformers). Then spray water to realize the conductivity of the membrane surface, divide the area, detect the potential of the membrane surface in each area, and use the physical properties of the electric field to determine whether each area is leaking. It mainly detects the leakage of the plane area, which is mostly used for temporary detection before operation and use. It does not have the function of continuous monitoring. Once it is put into production and use, the detection difficulty will increase ...
