Underground diaphragm wall joint structure and waterproof construction method thereof
The invention discloses an underground diaphragm wall joint structure and a waterproof construction method thereof. In the structure, a joint between adjacent groove sections of the underground diaphragm wall is a double-tenon-shaped joint with a continuous turning curve; a sectionable post-grouting waterproof structure is arranged at the position of the joint and comprises a plurality of sections of grouting pipes and grouting guide pipes connected with the two ends of each section of grouting pipe. All the sections of grouting pipes are sequentially connected in a lap joint mode from top to bottom, one end of each grouting guide pipe is connected with the corresponding grouting pipe, and the other end of each grouting guide pipe is a temporarily-plugged grouting opening. According to the continuous wall, the double-tenon-shaped joints with the continuous turning curves are adopted for the different groove sections, and the water seepage paths can be greatly increased; the sectionable post-grouting waterproof structure is arranged at the joint, grout is limited within a certain range of the joint of the underground diaphragm wall for grouting, so that the sectionalized grouting effect is achieved, and the engineering cost can be saved; and the anti-seepage performance and the overall stability of the underground diaphragm wall are improved.
本发明公开了一种地下连续墙接缝结构及其防水施工方法。本发明结构中，地下连续墙的相邻槽段之间的接缝为具有连续转折曲线的双榫形接缝；位于接缝的位置设置有可分段后压浆防水结构，包括：多段注浆管和每段注浆管两端连接的注浆导管；各段注浆管之间上下依次搭接连接，注浆导管的一端与注浆管连接，另一端为被临时封堵的注浆口。本发明连续墙不同槽段采用连续转折曲线的双榫形接缝，可极大增加渗水路径；在接缝处设置的可分段后压浆防水结构，将浆液限定在地下连续墙接缝一定范围内进行注浆，以达到分段注浆效果，可节约工程成本；提高地下连续墙的防渗性能和整体稳定性。
