Deep foundation pit inner support dismantling method
The invention relates to a deep foundation pit inner support dismantling method. A support structure is annular, and the dismantling method comprises the following steps that a structure bottom plate is constructed in a foundation pit; a layer of main body structure is constructed upwards on the structure bottom plate; the foundation pit is divided into a first construction area and a second construction area, and the part, located in the first construction area, of a first supporting structure at the bottom is dismantled; a layer of main body structure is constructed upwards in the first construction area, the bottommost supporting structure in the first construction area and the bottommost supporting structure in the second construction area are dismantled at the same time, a layer of main body structure is constructed upwards in the second construction area, and the step is repeated until the main body structure in the foundation pit is constructed; and the part, located in the second construction area, of the supporting structure at the top of the foundation pit is dismantled. The construction safety is guaranteed, and meanwhile the construction efficiency is also improved.
本发明涉及一种深基坑内支撑拆除方法，支撑结构呈环型状，拆除方法包括如下步骤：于基坑内施工结构底板；于结构底板上向上施工一层主体结构；将基坑划分成第一施工区域和第二施工区域，拆除底部第一道支撑结构位于第一施工区域内的部分；在第一施工区域内向上施工一层主体结构，同时拆除第一施工区域内最底部的一道支撑结构和第二施工区域内最底部的一道支撑结构，在第二施工该区域内向上施工一层主体结构，重复该步骤直至施工好基坑内的主体结构；拆除基坑顶部的支撑结构位于第二施工区域内的部分。本申请保障了施工的安全性，同时也提高了施工效率。
