Rapid construction method for ultra-large rectangular continuous open caisson underground station in soft soil stratum
The invention discloses a rapid construction method for an ultra-large rectangular continuous open caisson underground station in a soft soil stratum, which comprises the following steps of: dividing a continuous open caisson into seven open caisson sections, sequentially naming the open caisson sections as open caisson sections 1-7 from front to back, manufacturing each open caisson section for four times and sinking for two times, and correspondingly completing manufacturing of a main body of the open caisson section for one time; the sinking of the two sections of main bodies of the open caisson is correspondingly completed through one-time sinking, the continuous open caisson is divided into three stages for construction, the first stage is that the seventh open caisson moves in advance, the second stage is that the first, third and fifth open caissons follow up after meeting conditions, the third stage is that the second, fourth and sixth open caissons are constructed, and finally connecting sections between the adjacent open caissons are communicated to form a complete station main body. The construction process of the continuous open caisson in the construction process of building the rail transit underground station through the continuous open caisson is optimized, and on the premise that the safety and stability of the continuous open caisson are met, the construction progress is accelerated as much as possible, the cost input is reduced, and the construction efficiency is improved.
本发明公开了一种软土地层超大矩形连续沉井地下车站快速施工方法，将连续沉井设计分为7节沉井，由前向后依次命名为1号沉井～7号沉井，每节沉井分为4次制作、2次下沉，1次制作对应完成沉井一节主体的制作，1次下沉对应完成沉井两节主体的下沉，将连续沉井划分为三个阶段进行施工，一阶段7号沉井先行，二阶段1号、3号、5号沉井具备条件后跟进，三阶段2号、4号、6号沉井施工，最后贯通相邻沉井间连接段，形成完整的车站主体。本发明通过对连续沉井建造轨道交通地下车站施工过程中的连续沉井施工工序优化，在满足连续沉井安全稳定的前提下，尽可能地加快施工进度，减少成本投入，提高施工效率。
