Professional geomembrane inspection, leakage of geomembrane during laying:

After the completion of the design and construction of the anti-seepage system of the landfill, the integrity test of the geomembrane shall be carried out in accordance with the specifications. Detecting the anti-seepage system and whether it is qualified is an important theoretical basis for construction quality acceptance. The geomembrane detection method of the landfill reservoir area and the leachate treatment infrastructure (including the adjustment tank) can use the double electrode method, the water gun method and the electric spark method to determine the location of the damaged hole. During operation and after closure, for landfills with leachate leakage, the high-density resistivity method can be selected to delineate the contaminated area.

The geomembrane inspection system needs to detect leaks and damage:

1. The leakage and damage detection system should be able to timely, accurately and effectively detect and locate the damaged geomembrane holes in the landfill area, leachate adjustment tank, liquid collection well, and closed site coverage areas with serious leakage and pollution problems. structure.

2. In the area where the granular leachate diversion layer or sand (soil) protective layer is laid on the geomembrane at the bottom of the buried reservoir area, seepage treatment facilities such as leachate adjustment tanks and geomembrane anti-seepage collection wells should be adopted. And after the completion of the construction, the leakage damage detection of the geomembrane detection will be carried out.

3. The composite geomembrane sealing system can be used for leakage analysis and damage detection. Secondly, in view of the inevitable defects in each stage of the geomembrane anti-seepage project, the damage location of the anti-seepage system is carried out.

At present, the anti-seepage technology system based on the anti-seepage geomembrane can be widely used in landfills in my country. The anti-seepage geomembrane was damaged due to analysis of various problems during production, supply and installation. Therefore, geomembrane testing is very important. The leakage problem of geomembrane testing is also crucial. Everyone needs to pay attention at work.
