Method for replacing temporary supporting plate strip on periphery of basement in foundation pit engineering
The invention belongs to the field of underground space development, and relates to a method for replacing a temporary support replacement plate strip on the periphery of a basement in a foundation pit project. The method is used for high-underground-water-level underground space development, and adopts the main technical scheme that after the foundation pit project implemented by a conventional sequential construction method is excavated to the foundation elevation, and a foundation bottom plate and a bottom plate periphery support replacement reach the design strength, the foundation bottom plate and the bottom plate periphery support replacement reach the design strength; and dismantling the lowest temporary support, constructing a basement structure floor slab and a wall body, and further constructing waterproof outside the basement. And under the condition that the external waterproof construction is completed, the foundation pit fertilizer groove is filled with flow-state solidified soil. And after the flow-state solidified soil reaches the design strength, the water and soil pressure outside the pit is balanced through the flow-state solidified soil, then temporary supports on the upper portion are dismantled, structural floors and walls of all layers of a basement are constructed, and waterproof performance outside the basement is achieved. The construction method is suitable for the situation of multi-layer underground space development of a high-underground-water-level central urban area, the construction cost of foundation pit engineering can be effectively saved, and meanwhile the waterproof effect of a basement in the normal use stage can be enhanced.
本发明属于地下空间开发领域的用于高地下水位地下空间开发中的一种基坑工程中替代地下室周边临时换撑板带的方法，主要技术方案为：待常规顺作法实施的基坑工程开挖至基底标高，且基础底板和底板周边换撑达到设计强度后，拆除最下一道临时支撑，施工地下室结构楼板和墙体，进而施工地下室外防水。在外防水施工完成的情况下，在基坑肥槽内填筑流态固化土。待流态固化土达到设计强度后，利用流态固化土平衡坑外水土压力，进而拆除上部各道临时支撑，施工地下室各层结构楼板和墙体、以及地下室外防水。其适用于高地下水位中心城区多层地下空间开发的情况，该施工方法能够有效节约基坑工程造价，同时可加强地下室正常使用阶段的防水效果。
