Information

Geomembrane inspection After the completion of the design and construction of the anti-seepage system of the landfill, the geomembrane damage inspection should be carried out according to the specifications. Checking whether the anti-seepage system is qualified is an important theoretical basis for construction quality acceptance. In the geomembrane detection method for the landfill reservoir area and the leachate treatment infrastructure (including the adjustment tank), the location of the damaged hole can be determined by the double electrode method, the water gun method and the electric spark method. During operation and after closure, for landfills with leachate leakage, the high-density resistivity method can be selected to delineate the contaminated area.

The leakage and damage detection system for geomembrane detection should be able to timely, accurately and effectively detect and locate the geotechnical work in areas with serious leakage and pollution problems such as landfill areas, leachate adjustment tanks, collection wells, and enclosed areas. The membrane is broken in the pore structure.

Geomembrane detection 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, the seepage treatment facilities such as the leachate adjustment tank and the geomembrane anti-seepage collection well are used, and the construction is completed Then carry out leakage and damage detection.

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 of the anti-seepage system is located.

At present, the anti-seepage technology system based on anti-seepage geomembrane can be widely used in landfills in my country. During the production, supply and installation of the impermeable geomembrane, we analyzed various problems and damaged them.

After the completion of the design and construction of the anti-seepage system of the landfill, the geomembrane inspection integrity test shall be carried out in accordance with the specifications. Checking whether the anti-seepage system is qualified is an important theoretical basis for construction quality acceptance. The geomembrane detection methods of landfills and leachate treatment infrastructure (including conditioning tanks) can use double electrode method, water gun method and electric spark method to determine the location of damaged holes. 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 leakage and damage:

1. Leakage and damage detection system should be able to timely, accurately and effectively detect and locate the damaged pore structure of geomembrane in areas with serious leakage and pollution problems, such as landfill area, leachate adjustment tank, collection well and closure Field coverage area.

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 used, and the After the construction is completed, the leakage damage detection of the geomembrane detection is 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 of the anti-seepage system is located.

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