Slurry stopping device for preventing streaming of vertical joint of prefabricated diaphragm wall and construction method
The invention belongs to the field of underground structure engineering, and particularly discloses a slurry stopping device for preventing streaming of a vertical connector of a prefabricated underground diaphragm wall and a construction method.The slurry stopping device comprises a rubber bag arranged in an end groove of the prefabricated underground diaphragm wall and a steel water pipe installed on the rubber bag; the rubber bag is tightly attached to the side wall of the end groove of the prefabricated diaphragm wall and the vertical seam of the prefabricated diaphragm wall after the steel water pipe expands after being injected with water. When grouting and filling of the wall bottom and the side wall need to be carried out in a segmented mode, the grout stopping device is inserted into the end groove of the segment, water is injected into the rubber bag through the steel water pipe on the ground, and along with gradual expansion of the water injection bag, the grout in the end groove is gradually discharged till the rubber bag is expanded to be tightly attached to the groove wall and the vertical joint face of the prefabricated diaphragm wall; the vertical joint face of the prefabricated diaphragm wall is protected from being wrapped by the side wall grouting slurry, and it can be guaranteed that the subsequent groove section prefabricated diaphragm wall is smoothly inserted and spliced for construction.
本发明属于地下结构工程领域，具体公开了一种预制装配式地连墙竖向接头防绕流的止浆装置和施工方法，所述止浆装置包括设置于预制地连墙端头槽内的橡胶囊袋和安装于橡胶囊袋上的钢质水管，所述橡胶囊袋通过钢质水管注水膨胀后紧贴预制地连墙端头槽的侧壁及预制地连墙竖缝。当需要分段进行墙底及侧壁注浆填充时，将止浆装置插入到本段端头槽内，在地面通过钢质水管向橡胶囊袋内注水，随着注水囊袋逐渐膨胀，逐步排出端头槽内的泥浆，直至橡胶囊袋膨胀到紧贴沟槽壁、预制地连墙竖向接缝面，起到保护预制地连墙竖向接头面不被侧壁注浆浆液包裹，能够保证后续槽段预制地连墙顺利插入拼装施工。
