Working well foundation pit support replacing device and method without inverted support
The invention provides a working well foundation pit inverted support-free support changing device and method. The working well foundation pit inverted support-free support changing device is characterized in that an enclosure structure of a working well mainly comprises a vertical underground diaphragm wall, a horizontal concrete support and a horizontal steel support; after the foundation pit is excavated, when construction of a main body structure is started, all supports and surrounding purlin structures of the supports need to be dismantled from bottom to top in sequence; by means of the supporting optimization design method, the strength requirements of the foundation pit excavation stage, the main body structure construction supporting removal stage and the shield well use stage are considered, the positions of the concrete supports and the surrounding purlins are optimally designed, the fourth concrete support and the surrounding purlins of the fourth concrete support are reserved in the later supporting removal process, and the remaining supports are sequentially removed from bottom to top; the main body middle plate and the ring frame beam structure also serve as a main body structure; according to the method, through the optimal design of the foundation pit support, the position of the concrete support-enclosing purlin is optimized, and the temporary support is optimized into a permanent support structure, so that the construction material is saved, the construction procedure is simplified, the construction progress is accelerated, and the construction cost is reduced.
本申请提供的一种工作井基坑无倒撑换撑装置及方法，包括：工作井的围护结构主要包括竖向的地下连续墙和水平方向的砼支撑、钢支撑；待基坑开挖完毕之后开始主体结构施工时，需要从下向上依次拆除全部的支撑及其围檩结构；利用本支护优化设计方法，兼顾基坑开挖阶段、主体结构施工拆撑阶段以及盾构井使用阶段的强度要求，对砼支撑和围檩的位置进行优选设计，在后期的拆撑过程中保留第四道砼支撑及其围檩（剩余支撑从下往上依次拆除），使其兼做主体结构的主体中板和环框梁结构；该方法通过基坑支护的优化设计，优选砼支撑‑围檩的位置，将临时性支撑优化为永久性支护结构，不但节省了施工材料，简化了施工工序，更加快了施工进度，降低了施工成本。
