Information

Geomembrane damage detection is a safe and effective guarantee for the anti-seepage system, which can improve the construction and operation management level of the artificial anti-seepage system during the environmental protection anti-seepage construction process; at the same time, it can find and repair the leakage and damage of the HDPE geomembrane in the anti-seepage system; guarantee Its reliability and safety.

Geomembrane damage detection can detect any shape of cracks. Geomembrane damage detection can detect any shape of openings, perforations, gaps, tears, punctures, cracks, holes, cuts or similar fractures; damage may cause liquids or solids to pass through. Resulting in unqualified anti-seepage treatment.

Geomembrane damage detection has a wide range of applications. Geomembrane damage detection can be used in industrial pools, fish ponds, artificial lakes, evaporation ponds, water conservancy and hydropower, tunnels and landfills; landfill covers, floating covers for regulating ponds, and red mud storage yards , Tailings pond, slag yard, solid waste yard, hazardous waste yard, etc.

The geomembrane damage detection method has accurate positioning, and the geomembrane damage detection can accurately locate the location of the damage and leakage; the geomembrane damage detection records the detection process and issues a detection technical report.

Before geomembrane testing, the testing equipment should be tested and calibrated experimentally. The distance between the detection line and the point should be determined according to the calibrated detection parameters and the coverage width of the instrument, and should meet the following requirements:

The main parameters such as the detection voltage should be determined according to the field test; the sensitivity of the equipment and instruments should be adjusted; the detection unit and detection grid should be divided according to the distance defense line determined by the calibration, and the detection line and detection point should be arranged. According to the data recorded by the instrument, use the grid data format or contour map to analyze the data, draw the data curve of the lines and points in each area, and find and determine the location of the missing points according to the curve. Geomembrane inspection, after repairing the damaged hole, retest the impermeable geomembrane within a radius of 5m until it is confirmed that there is no leakage or damage.
