Dam geomembrane _ Kim Chi Hua Yi (certified) _ geomembrane

"Kim Chi Hua Yi" brand polyethylene film products: HDPE impermeable membrane, LDPE flexible waterproof membrane, high-density polyethylene geomembrane used in domestic landfills, industrial landfills, hazardous waste landfills, waste landfill, solid waste landfill, tailings landfill, waste landfill, tail mine seepage and other solid waste, hazardous waste landfill project. Construction of solid waste landfill seepage generally use col, excavation and mining over landfill seepage. Impermeable layer on top of the landfill is to be tens of thousands of tons of landfill waste, it is generally more than the use of impermeable membrane thickness of 1.5mm, the width should be greater than 6 meters, reducing the weld seam. Because proved that 70% of landfill leakage occurs in the welding seam. Impermeable membrane surface can be rough slope, increasing friction coefficient, so the available volume is maximized. 1. The need to clean up the paved surface rolling leveling, digging blind ditch, cloth exhaust drains. More specifically, the primary treatment, according to the design requirements for processing. 2. After the laying of geotextile protective liner, HDPE impermeable membrane can be laid. Prepare sandbags and other heavy objects, the paved HDPE impermeable membrane compaction, let the wind blowing. When laying, welding seams should be minimized, according to the size of the actual site, select the most appropriate scheme laid. 3. Before welding, soldering first trial, according to the day's weather, select the appropriate welding parameters. Artificial lake geomembrane, you should use a professional welding equipment welding. A large area of ??welding, using dual hot-melt automatic welding machines crawling; T-shaped and cross-shaped scar welding and complement should be using hot-melt extrusion welding machine. The steep slope welding, can make use of a rope ladder or scaffolding. Welder Technician required safety measures. 5. The anchor trench excavation: anchoring groove dimensions of 50cm × 50cm × 50cm U-shaped groove, backfill or using plain concrete anchor; steep slope platform can dig dig trench anchor anchorage; anchoring nails rock layers and layering available anchored seal. Reinforced impermeable membrane impermeable membrane used for shallow slopes shallow slope (2.0m or so) of reinforcement, it was turned loose in situ expansive soil together form a composite reinforced soil salt Anti seepage geomembrane, - addressing the serious problem of shallow weathering fissure zone expansive soils exist, on the other hand, the composite reinforced soil on the lower part of the expansive soil retaining wall to form a flexible support and inhibit swelling of expansive soil deformation or offset Role expansion force to maintain slope stability. The specific approach is: First, shallow 2m (vertical slope) of expansive soil scarification, then layer by layer (each about 30cm) dense compacted to a certain degree, every layer of geogrid layers of soil, The outer edge of the slope should be folded back outsourcing, the final form of flexible retaining wall thickness of 2.0m. Impermeable membrane should be paved, the length of the slope within its depth should be designed to fold back portion of the length of outsourcing in the chemical tank around 1.5m Geomembrane, impermeable membrane type (single, double), models and specifications shall be design calculations. .. In the case of tensile strength to meet the requirements of geomembrane, two-way grid can be selected. Its performance is worth drawing attention to the anti-should be determined by experiment. Currently on the market kind of polyester geogrids manufactured, its strength is generally higher than the tensile strength of PP-way grid, up to 25? 80kN / m. Two layers of impermeable membrane spacing is about 0.6 ~ 0.8m. When laying impermeable membrane, should be carried out door-shaped anchor member, which in the end should be fixed in the soil body. When the grill covered it soil, should avoid walking machine directly on the grill.
