Abstract：
With the rapid growth of urban construction waste in China, the application of HDPE geomembrane in the garbage disposal center has made great breakthrough. However, due to various reasons, there have been a series of problems in the implementation of HDPE impervious layer, which makes it difficult to widely spread. Taking the most representative project of the garbage disposal center in Hangzhou region as an example, the construction technology of HDPE geomembrane laying, welding, testing and repairing are in-depth studied, then a HDPE geomembrane construction scheme is determined, which provides reference for similar engineering.
