Underground space development method for overall reciprocating translation of existing building above foundation pit
The invention belongs to the field of underground space development, and relates to an underground space development method for integral reciprocating translation of an existing building above a foundation pit, which comprises the following steps of: reinforcing a first support part area of the foundation pit to serve as a middle address for translation of the existing building, and performing construction preferentially, and translating the existing building from an original address to the middle address for the first time; constructing a pile foundation enclosure of the original site area of the existing building and forming an integral support, excavating the whole foundation pit to a base, and after the whole foundation pit is backbuilt to an underground first-layer plate of the underground structure, preferentially constructing an underground structure top plate of the final site area of the existing building; the existing building is jacked to the designed elevation at the middle site and then translated to the final site for the second time to be fixed to a newly-built final site underground structure top plate, a middle site translation platform is dismantled to complete sealing of the structure top plate, and economic and convenient overall development of the underground space below the existing building is achieved. The problem of underground space development below the existing building is solved, and good economic and construction period advantages are achieved.
本发明属于地下空间开发领域的一种既有建筑于基坑上方整体往复平移的地下空间开发方法，技术方案为：基坑首道支撑部分区域加强作为既有建筑平移用的中间址并优先施工，既有建筑由原址首次平移至中间址后，施工既有建筑原址区域的桩基围护并形成整体支护，基坑整坑开挖至基底，并整体回筑至地下结构地下一层板后，优先施工既有建筑终址区域地下结构顶板，既有建筑在中间址顶升至设计标高后第二次平移回终址位置与新建的终址地下结构顶板固定，拆除中间址平移平台完成结构顶板封闭，实现既有建筑下方地下空间经济便捷地整体开发。解决了既有建筑下方地下空间开发问题，并具有较好的经济和工期优势。
