Solid waste landfill:
垃圾填埋场渗漏污染环境危害非常巨大。土壤被污染后，将会盐碱化、毒化，土壤中的寄生虫、致病菌等病原体能使人致病。渗透也会污染地下水，并最终进入人类的食物链，对人体造成严重伤害。国外从80年代开始在垃圾填埋场防渗处理中使用1—2毫米厚的HDPE高密度聚乙烯土工膜，目前已成为一项成熟的技术并得到越来越多的应用。我国环保型垃圾填埋场起步较晚，但近年在国家环保总局的关注下及国民环保意识的提高，采取HDPE防渗处理的环保型垃圾填埋场已经在全国得到广泛应用。我公司拥有资深的产品技术工程师和施工工程师及数支专业的施工队伍，业务分布在全国各地，特别是在沿海一线的大型工程，及市政项目，积累着丰富的施工及服务经验，在行业中享有良好的声誉。
Leakage pollution environmental hazards of landfill is very great. The contaminated soil, salinization, will be poisoned, pathogenic bacteria, parasites and other pathogens in the soil can cause disease. Permeability also pollute the groundwater, and eventually enter the human food chain, causing serious harm to the human body. Abroad began to use 1 - 2 mm thick HDPE high density polyethylene geomembrane in seepage treatment in waste landfill from the age of 80, has become a mature technology and application is getting more and more. China's environmental protection type waste landfill site started late, but the increase in the State Environmental Protection Administration attention and national awareness of environmental protection in recent years, adopt environment-friendly garbage landfill HDPE impervious treatment has obtained the widespread application in the country. My company has a product engineer and construction engineer senior and a professional construction team, business distribution throughout the country, especially for large projects in coastal line, and municipal projects, accumulated the rich experience in construction and service, enjoy good reputation in the industry.

Polyethylene film series products: impermeable membrane, flexible waterproofing membrane, high density polyethylene geomembrane applied in MSW landfill, landfill, industrial hazardous waste landfill, waste landfill, solid waste landfill, landfill waste landfill, tailings, tailings and other solid waste mountain anti permeability, hazardous waste landfill project.
垃圾填埋场防渗施工：
Anti seepage construction waste landfill site:
固体废弃物垃圾填埋一般是利用山坳、开挖过的矿山等进行填埋防渗。填埋场的防渗层上面都是要填埋成千上万吨的垃圾，所以一般采用1.5mm以上厚度的防渗膜，幅宽也应大于6米，减少焊接缝。因为实践证明，填埋场的渗漏70%出现在焊接缝。坡面可采用糙面的防渗膜，增加摩擦系数，使可用容积达到最大化。
Solid waste landfill is generally the use of col, the mines were excavated landfill impermeable. Impervious layer above landfill can be tens of thousands of tons of garbage landfill impermeable membrane thickness more than 1.5mm, so the general use of the width, also should be more than 6 meters, reduce welding seam. Because the practice has proved that the 70% leakage landfill appears in the welding seam. Slope can adopt the rough surface of the impermeable membrane, increase the friction coefficient, the volume available to maximize.
将需要铺设的表面碾压清理找平，挖盲沟，布排气排水管道。更具体的基层处理，可根据设计要求处理。
Will need to surface cleaning roller compacted paving leveling, dig the blind ditch, cloth exhaust drainage pipeline. Primary treatment is more specific, according to the design requirements of processing.
铺设完土工保护衬垫，即可铺设防渗膜。准备沙袋等重物，将铺设好的防渗膜压实，不让风刮起。铺设时，应尽量减少焊接缝，根据实际场地尺寸，选择最合适的铺设方案。
After laying geotextile protection pad, can be paved impermeable membrane. Prepare sandbags and other heavy weights, impermeable membrane compaction will be paved, don't let the wind blow. When laying, should try to reduce the welding seam, according to the actual size of the field, choose the most suitable laying scheme.
焊接前，先进行试焊，根据当天的气候，选择适当的焊接参数。焊接时，应使用专业的焊接设备。大面积焊接，采用双轨热熔自动爬行焊接机;T字形和十字形的焊接和补疤，应采用热熔挤出式焊接机。
Before welding, the first test welding, according to the climate of the day, select the appropriate welding parameters. When welding, welding should use professional equipment. Large area with dual hot melt welding, automatic crawl welding machine; T shape and figure ten welding and repair scar, should use the hot melt extrusion welding machine.
陡峭的边坡焊接，可借助绳梯或脚手架。焊机技术员需做好安全措施。
The steep slope welding, can use rope ladders or scaffolding. Welding technician should do safety measures.
锚固沟开挖：锚固沟尺寸为50cm×50cm×50cm的U型沟，回填土或用素混凝土进行锚固;陡峭边坡可挖平台再挖锚固沟进行锚固;岩石层可用锚固钉和压条进行锚固密封。
Anchorage trench excavation anchorage groove dimensions for U type channel 50cm * 50cm * 50cm, backfill or anchorage with plain concrete; steep slope platform can dig dig anchor ditch anchor; anchorage sealing layer can be used for rock anchor nail and layering.
