Underground diaphragm wall joint connecting method based on slot milling machine construction
The invention discloses an underground diaphragm wall joint connecting method based on slot milling machine construction, is suitable for solving the problems that cracks, water leakage and quicksand are prone to occurring at joints of underground diaphragm walls in deep foundation pit engineering, and relates to the technical field of building civil engineering. The method comprises the steps that firstly, a first-stage groove section 1 of the underground diaphragm wall is grooved; secondly, a first-stage groove section reinforcement cage 2 is lowered; step 3, mounting an embedded pipe 3; fourthly, grooving is conducted on the second-stage groove section 6 through a groove milling machine, concrete at the end of the first-stage groove section and the embedded pipe 5 at the corresponding position are milled, and an arc-shaped underground diaphragm wall joint face is formed; and 7, second-stage groove section concrete is poured. According to the method, ultrahigh-pressure jet grouting pile reinforcement does not need to be conducted at the joints of the underground diaphragm wall, and the engineering cost is saved; and the risks of water leakage, quicksand, confined water inrush and the like of the foundation pit are reduced, the construction safety of foundation pit engineering is improved, and remarkable social and economic benefits are achieved.
本发明一种基于铣槽机施工的地下连续墙接缝连接方法，适用于深基坑工程解决地下连续墙接缝处容易发生裂缝和漏水流砂问题，涉及建筑土木工程技术领域。方法包括：步骤一，地下连续墙一期槽段1成槽；步骤二，下放一期槽段钢筋笼2；步骤三，安装预埋管3；步骤四，采用铣槽机进行二期槽段6成槽，铣切一期槽段端头混凝土与相应部位预埋管5，形成具有弧形的地下连续墙接缝面；直至步骤七，浇筑二期槽段混凝土。本方法不需要在地下连续墙接缝处进行超高压旋喷桩加固，节省了工程费用；降低了基坑漏水与流砂、承压水突涌等风险，提高了基坑工程施工安全性，具有显著的社会和经济效益。
