一种污水处理构筑物伸缩缝的不停水修复方法及修复结构
摘要：
本发明公开了一种污水处理构筑物伸缩缝的不停水修复方法，包括如下步骤：清除构筑物底面及侧面下端预设高度段的待修复伸缩缝的止水带表面的嵌缝材料，形成嵌缝；向嵌缝内填入密封胶形成密封胶层，密封胶层上表面低于嵌缝边缘；将遇水膨胀止水条嵌入嵌缝，遇水膨胀止水条下表面与密封胶层上表面紧密贴合；在遇水膨胀止水条上，遇水膨胀止水条与嵌缝相接处，以及嵌缝边缘涂覆填塞密封剂形成密封层。本发明还公开了采用上述方法形成的污水处理构筑物伸缩缝的不停水修复结构。本发明公开的技术方案与现有的修复方法相比，具有施工工程量小，施工设备少，施工人员专业性要求低及施工成本低等特点，适用于污水处理构筑物伸缩缝的不停水修复。
摘要（英）：

The invention discloses a continuous-water-supply repairing method of sewage treatment structure expansion joints. The method includes following steps: removing caulked joint materials on the surfacesof waterstops of to-be-repaired expansion joints of preset height sections at the lower ends of the undersurface and the side face of a structure to form caulked joints; filling each caulked joint with a sealant to form a sealant layer with the upper surface lower than the edge of the caulked joint; embedding a water-swelling waterstop strip in each caulked joint, wherein the lower surface of each the water-swelling waterstop strip is in close fit with the upper surface of the corresponding sealant layer; on each water-swelling waterstop strip, coating and filling a sealing agent at a position where each water-swelling waterstop strip and the corresponding caulked joint are connected and at the edge of each caulked joint. The invention further discloses a continuous-water-supply repairingstructure formed by adopting the method.
