【Abstract】 According to the comparison of several impervious films, the dependability and application of high density polyethylene (HDPE) film at city waste sanitary landfill were expounded in this paper. High density polyethylene (HDPE) film have many advantages, such as high-strength, imperviousness, corrosion resistance, age resistance, convenient to construct, and so on. Combined with preliminary design of Shenyang Laohuchong Waste Sanitary Landfill Project, the structure of landfill bottom and slope impervious layer which use HDPE film was introduced, and the choice and laying of HDPE film at waste sanitary landfill was also discussed in this article.更多还原
