Construction device and construction method for chiseling off underground diaphragm wall of existing subway station
The invention relates to the technical field of shield construction, in particular to a chiseling construction device and method for an underground diaphragm wall of an existing subway station. The chiseling construction device for the underground diaphragm wall of the existing subway station comprises a safety door, the safety door comprises a door frame and a door leaf, and the door frame comprises an annular frame and a partition plate arranged on the inner side of the annular frame; the annular frame is fixedly connected with the underground diaphragm wall and directly faces a chiseled area of the underground diaphragm wall; the partition plate divides the internal space of the annular frame into an upper part and a lower part; the two door leaves are arranged on the upper side and the lower side of the partition plate correspondingly. And in addition, a layered chiseling construction mode is adopted, collapse of the sandwich soil is effectively avoided, and therefore construction safety is guaranteed, and efficient and safe chiseling of the underground diaphragm wall in the geologically unstable area can be achieved.
本申请涉及盾构施工的技术领域，尤其是涉及一种既有地铁车站地下连续墙的凿除施工装置及施工方法。既有地铁车站地下连续墙的凿除施工装置包括安全门，包括门框和门扇，门框包括环形框以及设置在环形框内侧的分隔板；环形框与地下连续墙固定连接并正对地下连续墙凿除区域；分隔板将环形框内部空间分隔为上部和下部；门扇设置有两个并分别设置在分隔板的上侧和下侧。并且本申请采用分层凿除的施工方式，有效避免了夹心土的塌落，从而保障施工安全，有助于实现地质不稳定区域的地下连续墙的高效安全凿除。
