摘　　要：以北京通州广渠路东延道路工程部分标段明挖法穿河隧道防水项目为例,重点介绍了底板高分子自粘胶膜防水卷材与侧墙沥青基防水层转换搭接的技术要点。该项技术在工程实践应用中可使两种不同材质的防水卷材紧密结合,搭接后卷材与卷材之间的剥离强度符合标准要求,搭接效果良好,可为同类工程提供借鉴。Taking the waterproofing project of open cut river-crossing tunnel of the East Extension of Guangqu Road in Tongzhou,Beijing as an example,this paper emphatically introduces the technical key points of the conversion and overlapping of self-adhesive polymer film reinforced waterproofing membrane on the bottom plate and the bituminous waterproofing layer on the side wall.The application of this technology in engineering practice can make waterproofing membranes of two different materials closely combined.The peeling strength between the membranes after overlapping meets the standard requirements,and the overlapping effect is excellent.It can provide reference for similar projects.
