Concrete panel tensioning joint and peripheral joint surface water stop structure and construction method thereof
The invention provides a concrete panel tensioning joint and peripheral joint surface water stop structure and a construction method thereof, relates to the technical field of rockfill dam construction. The joint surface water stop structure comprises a groove formed in the end of a joint, an elastic supporting body is bonded into the groove through an interface adhesive, and a compressible supporting body is fixed to the surface of the elastic supporting body. The panel surfaces of two sides of the compressible supporting body are brushed or scraped with interfacial agent layers, flexible composite coatings are bonded to the surfaces of the compressible supporting body and the interfacial agent layers, and the flexible composite coatings include single component polyurea layers and matrixcloth layers compounded in the middle of the single component polyurea layers. The problems of complex construction procedure and poor seepage prevention of an existing concrete panel tensioning joint and peripheral joint surface water stop structure are solved.
本发明提供了一种混凝土面板张性接缝及周边缝表层止水结构及其施工方法，该接缝表层止水结构其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可压缩支撑体，可压缩支撑体两侧的面板表面上涂刷或刮涂有界面剂层，可压缩支撑体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。涉及堆石坝施工技术领域，解决了现有混凝土面板张性接缝及周边缝表层止水结构施工工序复杂且防渗性差的问题。
