Reinforcing structure for defect area of pre-constructed diaphragm wall and construction method of reinforcing structure
The invention relates to a reinforcing structure for a defect area of a pre-constructed diaphragm wall and a construction method of the reinforcing structure, the defect area is located on the side, close to a post-constructed diaphragm wall, of the pre-constructed diaphragm wall, the setting direction of the post-constructed diaphragm wall intersects with the setting direction of the pre-constructed diaphragm wall, and the end of the post-constructed diaphragm wall is arranged close to the defect area. The reinforcing structure comprises a plurality of cast-in-situ bored piles arranged on the side, away from the foundation pit, of the defect area in a driving mode in the arrangement direction of the post-construction diaphragm wall, and part of the cast-in-situ bored piles are located on the side, away from the foundation pit, of the post-construction diaphragm wall. The multiple MJS construction method piles are arranged on the side, close to the foundation pit, of the defect area and the side, away from the foundation pit, of the defect area in a driving mode, and every two adjacent MJS construction method piles are partially overlapped. The cast-in-situ bored pile is combined with the MJS construction method pile to reinforce the defect area, the risk caused by removing the defects in the defect area is avoided, the problem of supporting and water stopping is effectively solved, the enclosure replacement effect is good, and site construction is convenient.
本发明涉及一种先施工地连墙缺陷区域的加固结构及其施工方法，缺陷区域位于先施工地连墙靠近后施工地连墙的一侧，所述后施工地连墙与先施工地连墙的设置方向相交，所述后施工地连墙的端部靠近所述缺陷区域设置，所述加固结构包括：沿所述后施工地连墙的设置方向打设在所述缺陷区域远离基坑的一侧的多个钻孔灌注桩，有部分钻孔灌注桩位于所述后施工地连墙远离基坑的一侧；打设在所述缺陷区域靠近基坑一侧和远离基坑一侧的多个MJS工法桩，相邻的两个MJS工法桩间有部分重合设置。本发明利用钻孔灌注桩结合MJS工法桩补强缺陷区域，避免清除该缺陷区域内的缺陷带来的风险，有效解决支护止水难题，围护替代效果好，现场施工方便。
