地下工程外防外贴法施工集成防水技术

Integrated Waterproofing Technology of External Protected and External Pasted for Underground Project

地下工程中,卷材防水层与结构混凝土之间粘贴不紧密容易形成窜水通道,是引起渗漏的主要原因之一。地下工程外防外贴法施工中,采取集成防水的施工技术,使防水层与混凝土结构表面粘贴紧密,形成一个不窜水且具有协同作用的防水系统,这是防止地下工程发生渗漏的有效技术措施之一。

It＇s easy to form water channel if waterproof layer of membrane and the structure concrete is not pasted closely, which is one of the main causes of leakage in underground project. The strong bond between waterproof layer and structure concrete can be obtained by integrated waterproofing construction technology of external protected and external pasted, and the waterproofing system with synergistic effect and without water channel is formed, which is one of the effective technical measures to prevent leakage of underground project.
