摘要
随着生活垃圾填埋场环保要求的不断提高,填埋场要求铺设HDPE土工膜作为防渗结构层。HDPE膜作为一种热塑性树脂材料,具有热胀冷缩的特性,已铺设完成的HDPE膜会受冷发生悬空、受热发生褶皱,防渗系统的施工质量是生活垃圾填埋场的关键因素。本文主要分析了HDPE膜的胀缩特性及指导土工膜的铺设施工。
With the improvement of the environmental protection in municipal solid waste landfills, the landfills require laid HDPE geomembrane for anti-seepage layer. As a kind of thermoplastic resin material, HDPE membrane has the character of heat bilges and cold shrink, the laid HDPE geomembrane would occur this kind of phenomenon, anti-seepagesystem of the construction quality is a key factor in municipal solid waste landfills.This article mainly analyzes the swell-shrink characteristics of HDPE membrane and the instruction of geomembrane laying construction.
