Concrete face plate pressing joint surface layer water stop structure and construction method thereof
The invention provides a concrete face plate pressing joint surface layer water stop structure and a construction method thereof, and relates to the technical field of rockfill dam construction. The joint surface layer water stop structure comprises a groove formed in the end of a joint, an elastic supporting body is bonded in the groove through interface glue, an isolation layer is fixed to the surface of the elastic supporting body, interface agent layers are brushed or scraped on the surfaces of the panels on the two sides of the isolation layer, flexible composite coatings are bonded on the surfaces of the isolation layer and the interface agent layers, and each flexible composite coating comprises a single-component polyurea layer and a tire base cloth layer compounded in the middle of the single-component polyurea layer. The problems that an existing concrete panel pressing joint surface layer water stop structure is complex in construction procedure, high in manufacturing cost and poor in seepage resistance are solved.
本发明提供了一种混凝土面板压性接缝表层止水结构及其施工方法，涉及堆石坝施工技术领域，该接缝表层止水结构包括设置于接缝端部的沟槽，沟槽中通过界面胶粘接有弹性支撑体，弹性支撑体的表面固定有隔离层，隔离层两侧的面板表面上涂刷或刮涂有界面剂层，隔离层和界面剂层的表面上粘接有柔性复合涂层，柔性复合涂层包括单组份聚脲层和复合于单组份聚脲层中间的胎基布层。解决了现有混凝土面板压性接缝表层止水结构施工工序复杂、造价高、防渗性较差的问题。
