Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] This embodiment is developed aiming at the leak point detection of the high-density polyethylene (HDPE) geomembrane just after construction.

[0024] Taking the landfill as an example, please refer to Fig. 1, there is a conductive liquid container 10 in the detection device of the present invention, this container is made by the good metal of electrical conductivity, and connects this container housing with a pole of power supply by a wire connected; the bottom of the container is covered with a layer of conductive liquid throughput cotton 20, and at least one water outlet hole 30 is provided at the bottom of the container where the conductive liquid throughput cotton is covered. superior. An injection hole 31 is provided in the upper part of the container for injecting conductive liquid. A movable emitter electrode A is formed by the above s...

Abstract

The invention relates to a dipole testing method and device for impervious barrier that puts a movable emitting electrode on geomembrane, and a receiving electrode would be embedded in earth outside detecting area. A power supply is set between emitting electrode and receiving electrode. Circuit loop would be formed by conductive liquid and receiving electrode. In the testing device, the conductive liquid container made from metal is used as emitting electrode, which connects to one electrode of power supply. At least one water outlet is set at the bottom of container, and conductive liquid is covered by gorge and disgorge cotton. A receiving electrode made from metal is connected to another electrode of power supply, and an insulated handle is connected on conductive liquid container, which has power supply control switch and alarming device on it.

Description

technical field [0001] The invention relates to a double-electrode detection method for leakage of an anti-seepage layer. [0002] The present invention also relates to a detection device for realizing the above detection method. Background technique [0003] In order to prevent groundwater from being polluted, such as landfills, the anti-seepage lining system is an essential facility for landfill construction. Its function is to isolate the inside and outside of the landfill and control leachate from entering clay and groundwater. The general materials of this system mainly include clay and artificial synthetic materials. The most commonly used artificial synthetic material is high-density polyethylene (HDPE). In the investment of landfill construction, the investment in anti-seepage layer is huge. Due to the quality of HDPE itself or construction reasons, the anti-seepage layer of the landfill is often damaged. Therefore, it is particularly important to find the location ...
