Leakage plugging construction method for diaphragm wall joint with waterproof curtain on outer side
The invention discloses a leakage plugging construction method for a connector of a diaphragm wall with a waterproof curtain on the outer side, which is used for plugging a crack at a leakage part of the diaphragm wall when a waterproof curtain reinforcing body is arranged on the outer side of the diaphragm wall, and comprises the following steps of cleaning and crack inspection; inserting a flow guide tube and a drainage tube; crack reinforcement of the leakage part; grouting holes are drilled, grouting pipes are arranged, and grouting pipelines are connected; grouting and plugging; grouting is completed, and a waterproof material is filled. According to the method, the tiny gap between the diaphragm wall and the waterproof curtain reinforcing body is utilized, small drilling and grouting equipment is utilized, the gap is filled with double-liquid slurry, water stopping is conducted from the leakage root, the mode that in a traditional grouting technology, a drill rod is inserted into a guide hole in the outer side of the diaphragm wall for grouting is replaced, and rapidness and high efficiency are achieved. The mode that the flow guide pipe is used for drainage is adopted, the situation that in the grouting process, double-liquid slurry diffuses everywhere and is not concentrated, and grouting fails is avoided, and a traditional back pressure soil method is replaced.
本发明公开了一种外侧有止水帷幕地连墙接头渗漏封堵施工方法，用于地连墙墙外侧设有止水帷幕加固体时地连墙渗漏部位裂缝的封堵，封堵施工方法包括以下步骤：清理、裂缝检查；插设导流管及引流管；渗漏部位裂缝加固；钻取注浆孔，打设注浆管并连接注浆管路；注浆封堵；完成注浆，填充防水材料。本发明利用地连墙与止水帷幕加固体之间存在的细微空隙，利用小型钻孔注浆设备，将空隙填充双液浆，从渗漏根部进行止水，替代传统注浆工艺中在地连墙外侧引孔插入钻杆进行注浆的方式，快捷高效。利用导流管进行引流的方式，避免注浆过程中，双液浆到处扩散不集中，注浆失效，替代传统的反压土方法。
