高分子类防水卷材在城市轨道交通防水工程中的应用探讨

Application of Polymer Waterproofing Membrane in the Waterproofing Engineering of Urban Rail Transit

目前,国内明挖法结构和矿山法结构施工的城市轨道交通防水工程,普遍采用预铺防水卷材和塑料防水板进行柔性防水设计。针对这两类高分子防水材料的选用原则和施工工艺进行了论述,并对相应的应用技术难题和发展趋势进行了探讨。

At present,the waterproofing engineering of urban rail transit constructed by open cut structure and mine structure generally adopts pre-laid waterproofing membrane and plastic waterproofing board for flexible waterproofing design.The selection principles and construction technology of these two kinds of polymer waterproofing materials are expounded,and the corresponding application technical problems and development trend are discussed as well.
