Water channeling prevention grouting structure pre-buried in underground diaphragm wall and construction method of water channeling prevention grouting structure
The invention discloses a water channeling prevention grouting structure pre-buried in an underground diaphragm wall and a construction method of the water channeling prevention grouting structure. The water channeling prevention grouting structure comprises the underground diaphragm wall and a main body structure side wall. The grouting structure is pre-buried in a reinforcement cage of the ground wall, a pipe body is protected by ground wall concrete after the ground wall is poured, the strength is greatly improved, and the grouting structure is a hidden grouting system and has no adverse effect on procedures such as waterproof paving of the structure; a main body grouting pipe of the system is formed by improving a ground wall sounding pipe, and the ground wall sounding pipe is reutilized, so that the material cost of the pre-embedded grouting pipe is greatly reduced; the same grouting section is provided with two independent grout outlets, and single-liquid grout or double-liquid grout injection can be selected according to different hydrogeology and structure defect conditions; the system can achieve a synergistic effect with supplementary reinforcement grouting after main body structure pouring is completed, and the supplementary effect on structure waterproof can be greatly improved after the synergistic effect of the system and the supplementary reinforcement grouting; the follow-up water leakage risk of the structure can be greatly reduced, and the comprehensive investment of follow-up structure through crack plugging is reduced.
本发明公开了一种预埋于地下连续墙内部的防窜水注浆结构及其施工方法，包括地下连续墙和主体结构侧墙。本发明注浆结构预埋于地墙钢筋笼内部，地墙浇筑后管体受地墙混凝土保护，强度大大提升，且为隐蔽注浆系统，对结构防水铺贴等工序无不良影响；该系统的主体注浆管为地墙声测管改良而来，将地墙声测管二次利用，大大降低了预埋注浆管材料成本；同一注浆断面有两个独立出浆口，可根据不同水文地质及结构缺陷情况选择单液浆或双液浆注入；该系统可与主体结构浇筑完成后的补充加固注浆协同作用，二者协同作用后对结构防水的补足效果可大大提升；可大大减少结构后续渗漏水风险，降低后续结构贯通裂缝封堵的综合投入。
