Deep foundation pit permanent waist beam waterproof device and construction method
The invention relates to the technical field of deep foundation pit construction, in particular to a deep foundation pit permanent waist beam waterproof device and a construction method.The deep foundation pit permanent waist beam waterproof device comprises an underground diaphragm wall, and a plurality of mounting holes are formed in the outer wall of one side of the underground diaphragm wall; the method has the beneficial effects that concrete on the surface of the steel bar connector is chiseled away so that the steel bar connector can be exposed, a back-attached type water stop belt is attached to the outer wall of the underground diaphragm wall, water-swelling water stop glue is brushed on the end portion of the steel bar connector, and the permanent waist beam is conveyed to a lofting position through hoisting equipment; the permanent waist beam and the underground diaphragm wall are fixedly connected through a steel bar connector, hoisting equipment is removed after the permanent waist beam is stably fixed, the upper surface and the lower surface of the permanent waist beam are cleaned and leveled, and a layer of cement-based permeable crystallization type waterproof material is brushed before the side wall of the post-pouring structure is poured. And two water-swelling water-stop strips are pasted and arranged at the front and back positions of the pre-buried galvanized steel sheet water-stop belt on the joint surface of the post-pouring structure side wall and the permanent waist beam, so that the joint surface is waterproof, and the construction of the post-pouring structure side wall is carried out.
本发明涉及深基坑施工技术领域，具体为一种深基坑永久腰梁防水装置及施工方法，包括：地下连续墙，地下连续墙的一侧外壁开设有若干个安装孔；有益效果为：凿除钢筋接驳器的表面混凝土使钢筋接驳器外露，在地下连续墙的外壁粘贴背贴式止水带，并在钢筋接驳器端部涂刷遇水膨胀止水胶，通过起吊设备将永久腰梁运送至放样位置，通过钢筋接驳器将永久腰梁与地下连续墙进行连接固定，待永久腰梁固定稳固后移除吊装设备，将永久腰梁上下表面，进行清理平整，在浇筑后浇结构侧墙前刷涂一层水泥基渗透结晶型防水材料，在后浇结构侧墙与永久腰梁接缝面预埋镀锌钢板止水带的前后位置，粘贴布置两道遇水膨胀止水条，用以接缝面防水，进行后浇结构侧墙的施工。
