Landfill cesspool HDPE geomembrane construction specifications

Grasp the key to put the minor during construction, seepage control system in the whole process is more critical laying HDPE geomembrane. Here we understand under specification cesspool HDPE impermeable membrane which construction. First of all, before laying to the appearance of quality HDPE impermeable membrane open packet inspection, and repair records have been found to produce mechanical damage and trauma, holes, breakage and other defects. ??? Secondly, HDPE geomembrane before cutting, by measuring the correlation dimension, then the actual cutting, laying in the membrane between the membrane and the membrane seams lap width of not less than 100mm, so that the seam arrangement direction parallel to the maximum toe line, which are arranged in the direction of the gradient. ??? Again, laying HDPE geomembrane should be sought to weld at least, under the premise of guaranteeing quality, try to save raw materials. But also easy to ensure quality. Usually in the corner and deformity lots, should be to minimize the short length of the seam. In addition to special requirements, the slope is greater than 1: 6 slopes in the slope from the top or the stress concentration range of 1.5 meters, as far as possible with no welds. ??? Finally, HDPE geomembrane laying, we must try to avoid artificially folds. After completion of the laying HDPE geomembrane, should try to reduce the pressure in the above the membrane surface as walking, moving tools, who can cause harm to the HDPE film objects should not be placed on the film or the film carry walking, so as not to cause accidental damage film. Function: seepage, isolation purposes: 1. landfill, sewage or waste treatment seepage 2. Dyke, lake dam, tailings dam, water dam and reservoir area, channels, build liquid pool, 3 subway, basement and tunnels, tunnel impermeable lining. The roadbed and other foundation saline seepage 5. embankment, dam levels impervious blanket, ground vertical impermeable layer, the construction cofferdam, scrap plant. 6. seawater, freshwater farms. 7. roads, highways, railways foundation, expansive soil and loess wet stuffing waterproof layer 8. roofing seepage.
