Construction Of Landfill

Solid waste landfill generally uses excavation of mines and another landfill to try to to the seepage control. there'll be thousands of plenty of garbage to be buried, so generally use the 1.5mm thickness of top quality low price aquaculture geomembrane, the width should be greater than 6 meters, to scale back welding seam. because it seems, 70% of the leakage from landfills occurs in welded seams. Rough geomembrane is often utilized in slope to extend friction coefficient and maximize available volume. 1. Rolling and leveling the surface to be laid, digging blind ditches and laying exhaust and drainage pipes. More specific grassroots treatment, consistent with the planning requirements. 2. After laying the geotechnical protection liner, the HDPE anti-seepage film is often laid. Prepare sandbags and other heavy objects and compaction the laid wholesale HDPE geomembrane to stop the wind from blowing. During laying, welding joints should be minimized and therefore the best-suited laying scheme should be selected consistent with the particular site size. 3. Test welding shall be administered before welding, and appropriate welding parameters shall be selected consistent with the climate of the day. When welding, use professional welding equipment. Large area welding, using double-track hot melt automatic crawling welding machine; For T – shaped and cross-shaped welding and scarring, hot-melt extrusion welding machine shall be used. 4. Steep slope welding with a ladder or scaffold. Welder technicians should take safety measures. 5. Anchorage ditch excavation: the anchorage ditch may be a u-shaped trench with a size of 50cm 50cm 50cm, which is backfilled with soil or anchored with plain concrete; The platform of the steep slope is often dug then the anchorage ditch are often dug for anchoring. Rock layers are often bolted and sealed with bolts and batten.
