Causes and repair methods of anti-seepage geomembrane damage
May 07,2024
Geomembrane integrates anti-seepage and drainage, and has been gradually used in reinforced anti-seepage projects such as water conservancy, transportation, tunnels, airports, metallurgical tailings, garbage disposal sites, and roof anti-seepage. Here is a summary of the following causes of damage to the anti-seepage geomembrane and its repair methods.
Corresponding welding work must be done during construction of the anti-seepage geomembrane, and there are requirements for welding.
The joint treatment of anti-seepage geotextile is a key construction procedure. Thermal welding method is generally used. The surfaces where the PE films are connected are heated to melt the surface, and then fused into one through pressure. Before welding the anti-seepage geotextile, it is necessary to adjust the two sides of the PE single film at the seam to make the overlap width. The overlap width is generally 6~8cm and is smooth and wrinkle-free.
For the laid anti-seepage geotextile, the edge joints are required to be free of oil, moisture, dust, etc. Use a welding machine to weld the anti-seepage geotextile. Anti-seepage geomembrane is a widely used geotechnical material. Its high performance has been widely praised by users. However, anti-seepage geomembrane is prone to damage during transportation and construction. Damaged holes will affect the anti-seepage effect of the project. .
Standards are followed for the material selection standards, construction welding methods and requirements of anti-seepage geomembranes. The construction of anti-seepage geomembrane materials requires a strict and scientific construction quality system. The main causes of damage to anti-seepage geomembranes are these. We must try to avoid damage and use the geomembrane reasonably to effectively extend its service life.
