Connecting structure of underground diaphragm wall joint and construction method of connecting structure
The invention relates to a connecting structure of an underground diaphragm wall joint and a construction method of the connecting structure. The connecting structure comprises a connecting piece, a sealing plate and a groove, wherein the connecting piece is embedded into the end part of a first unit segment and a part of the connecting piece protrudes and extends outwards, and the protruding andextending part of the connecting piece is fixedly connected with the end part of a reinforcement cage of a second unit segment; the sealing plate is fixed to the protruding and extending part of the connecting piece and protrudes and extends to the direction of the second unit segment, and the bottom level of the sealing plate is larger than the bottom level of the connecting piece; and the groovecorresponds to the sealing plate and forms in the end part of the reinforcement cage of the second unit segment. The sealing plate is placed in the groove and is fixedly connected with the bottom ofthe groove, and after the second unit segment is formed through pouring, the sealing plate is embedded into the second unit segment. The problem of difficult pulling of a counter-force box is effectively solved, the restriction of the counter-force box on the joint arrangement depth is avoided, the waterproof performance of the connecting position is ensured, and the structure is simple and easy to realize.
本发明涉及一种地下连续墙接头的连接结构及其施工方法，包括：埋设于第一单元段的端部且部分向外凸伸的连接件，该连接件的凸伸部分供与第二单元段的钢筋笼的端部固定连接；固定于连接件的凸伸部分且向第二单元段的方向凸伸的止水板，该止水板的底部标高高于连接件的底部标高；以及对应止水板且形成于第二单元段的钢筋笼的端部的凹槽，该止水板置于凹槽中并与凹槽的底部固定连接，浇筑形成第二单元段后，该止水板埋设于第二单元段中。本发明有效的解决了反力箱起拔困难的问题，避免了反力箱对接头设置深度的限制，保证了连接处的防水性能，且结构简单易于实现。
