Layered breaking construction method for underground diaphragm wall at connection position of new subway station and old subway station
The invention relates to the technical field of building foundation pit construction, in particular to a layered breaking construction method for an underground diaphragm wall at the connection position of a new subway station and an old subway station. Determining the position of a continuous wall at the connection of the new and old stations and the surrounding environment; an enclosure wall is arranged in a new station area at the connection position; a first support is arranged between the bottom area of the continuous wall and the enclosure wall; a support is arranged between the continuous wall and the enclosure wall, and a bottom plate is arranged at the bottoms of the continuous wall and the enclosure wall; dividing a breaking layer by the continuous wall; the first support and the bottom plate are reserved, and the middle continuous wall is broken in a layered mode according to the sequence; a movable bidirectional wall breaking device is installed at the wall head of the continuous wall and used for breaking the wall head of the continuous wall in a movable mode. The continuous wall at the connection position is stably broken, the space needed by breaking is reduced, damage to an existing structure is reduced, the construction speed can be increased, and construction safety is guaranteed. The method is mainly applied to layered breaking construction of the underground diaphragm wall at the connection of new and old subway stations.
本发明涉及建筑基坑施工技术领域，更具体而言，涉及一种新旧地铁车站接驳处地下连续墙分层破除施工方法。确定新旧车站接驳处连续墙的位置及周边环境；在接驳处新车站区域设置围护墙；在连续墙底部区域和围护墙之间设置第一道支撑；在连续墙与围护墙之间设置支撑，并在连续墙与围护墙底部设置底板；连续墙划分破除层；将第一道支撑与底板保留，按照顺序对中间的连续墙进行分层破除；连续墙墙头安装可移动式双向破壁器，对连续墙墙头部位移动式破除。本发明对接驳处连续墙进行稳定破除，缩小破除所需要的空间，减少对已有结构的破坏，并能加快施工速度，保证施工的安全。本发明主要应用于新旧地铁车站接驳处地下连续墙分层破除施工方面。
