新型聚乙烯瓦斯隔离防水卷材的施工工艺研究

Preparation and Research of PE Gas Splitter Plate for Tunnel Construction

瓦斯气体泄漏影响隧道施工安全,市售瓦斯隔离板不能同时满足防水和阻气两大性能要求,且施工繁琐。而新型聚乙烯瓦斯隔离防水卷材由隔离层和泡沫层组成,施工简单。介绍了该卷材的特点和施工工艺,以及在瓦斯隧道施工中的控制要点。

The gas leakage affects the safety of tunnel construction.The gas isolation board sold in the market can not meet the requirements of waterproof and gas resistance at the same time and the construction is complicated.The new PE gas isolation waterproof board is composed of an insulating layer and a foam layer and has the advantages of simple construction.The production property,construction technology and the key points of construction controlling in the gas tunnel are introduced.
