Construction method for protecting building in-situ reservation and foundation pit cover excavation
The invention discloses a construction method for retaining an original site of a protection building and covering and excavating a foundation pit, which utilizes a support changing structure and a jacking device, takes a supporting pile as a supporting point, jacks and raises the whole protection building, and provides an operation space for a top plate. After construction of a first-layer structural beam plate is completed, the protection building integrally falls back to a top plate, earthwork and supports of a foundation pit below the top plate are normally constructed, and original site reservation and underground space development of the protection building are achieved. The bearing piles and the enclosure structure provide vertical support for the top plate and a supporting system in the foundation pit. The supporting piles are used as supporting points, the whole protection building is jacked and improved, and after the top plate is constructed and reaches the strength, the whole protection building falls back to the top plate, so that underground space development of the protection building is completed, and the protection building is reserved on the original site. The problems that a traditional underground development method of the protection building can cause certain damage to the protection building in the building translation process, building protection and repairing are not facilitated, and the construction cost is high are solved.
本发明公开了一种保护建筑原址保留与基坑盖挖的施工方法，利用换托结构和顶升装置，将支承桩作为支撑点，将保护建筑整体顶升提高，为顶板提供作业空间。在首层结构梁板施工完成后，将保护建筑整体回落至顶板上，顶板下基坑土方与支撑正常施工，实现保护建筑原址保留和地下空间开发。支承桩和围护结构为顶板与基坑内支撑体系提供竖向支撑。将支承桩作为支撑点，将保护建筑整体顶升提高，顶板施工并达到强度后，保护建筑整体回落至顶板上，不仅完成保护建筑地下空间开发，还实现了保护建筑在原址保留。本发明解决了保护建筑的地下开发的传统做法在建筑平移过程中会对保护建筑本身产生一定的损坏，不利于建筑保护修缮，且施工造价高的问题。
