Construction method for dismantling inner support of irregular deep and large foundation pit
The invention relates to the technical field of foundation pit supports, and discloses an irregular deep and large foundation pit inner support dismantling construction method which comprises the following steps that a foundation pit basement structure and an inner support are divided into different numbers of areas; constructing a raft and a negative four-layer basement main body structure area A at the bottom of the foundation pit; constructing a negative four-layer basement area B in the foundation pit, and removing a third support beam area 1 corresponding to the basement area A; a basement negative third layer A area main body structure is constructed in the foundation pit, and a third supporting beam second area is dismantled; the remaining basement negative third layer A area main body structure continues to be constructed in the foundation pit, and a third supporting beam area 3 is dismantled; and the steps are repeated until the main body structure in the foundation pit is constructed. A construction thought is provided for dismantling the irregular deep foundation pit through the diagonal bracing and angle brace supporting method, the safety of the whole foundation pit is guaranteed, the construction period can be shortened, and follow-up construction is accelerated.
本发明涉及基坑支撑技术领域，且公开了一种不规则深大基坑内支撑拆除施工方法，包括以下步骤：将基坑地下室结构和内支撑划分为数量不等的区域；于基坑底施工筏板以及负四层地下室主体结构A区；于基坑施工负四层地下室B区并拆除地下室A区对应第三道支撑梁1区；于基坑施工地下室负三层A区主体结构并拆除第三道支撑梁2区；于基坑继续施工剩余地下室负三层A区主体结构并拆除第三道支撑梁3区；重复上述步骤直至施工好基坑内的主体结构。本申请为不规则深基坑并采用对撑和角撑支撑方法拆除提供一种施工思路，保障了整体基坑安全性能够缩短工期，加快后续施工。
