Construction method for dismounting and replacing support of large connected complex deep foundation pit without partition wall
The invention relates to a large connected complex deep foundation pit support replacement construction method without a partition wall, which comprises the following steps of: firstly, presetting latticed columns and support connecting beams on one side of a support replacement position which is provided with a constructed main body structure bottom plate, a constructed main body structure column/wall and a constructed main body structure floor slab under the condition that the partition wall is not arranged; and then the foundation pit support can be detached and replaced by arranging a buttress wall and a buttress stand column, and the supporting axial force is underpinned to the buttress wall and the buttress stand column in an automatic servo system axial force compensation mode. Compared with the prior art, the support dismounting and replacing construction method for the large connected complex deep foundation pit without the partition wall has the advantages that support dismounting and replacing can be completed without blocking soil reserving and blocking excavation in actual construction, it can be preferentially ensured that key working procedures of a main structure are completed, the construction period can be greatly shortened, and the overall construction cost of a project is saved.
本发明涉及一种不设分隔墙的大型连体复杂深基坑拆换撑施工方法，换撑位置一侧已有施工完成的主体结构底板、主体结构柱/墙和主体结构楼板，在不设分隔墙的条件下，先预设格构柱和支撑连系梁，后可通过设置扶壁墙和扶壁立柱拆换基坑支撑，并采用自动伺服系统轴力补偿的方式将支撑轴力托换至扶壁墙和扶壁立柱上。与现有技术相比，本发明提供的不设分隔墙的大型连体复杂深基坑拆换撑施工方法在实际施工中无需分块留土、分块开挖即可完成拆换撑，能够优先确保主体结构关键工序完成施工，可大大缩短工期，节约工程总体造价。
