Shallow foundation rear-mounted composite pile reinforcing structure of building in active service and construction method of shallow foundation rear-mounted composite pile reinforcing structure
The application relates to a shallow foundation rear-mounted composite pile reinforcing structure of a building in active service and a construction method of the shallow foundation rear-mounted composite pile reinforcing structure. The construction method comprises the steps: digging a cast-in-place pile hole in the outer side of the shallow foundation, then drilling a steel pipe pile hole, and inserting a steel pipe pile into the steel pipe pile hole; arranging foundation bearing platforms on the upper portions of the cast-in-place piles and the steel pipe piles, and arranging pile core reinforcement cages, back pressure supporting plates and connecting cap plates on the upper portions of the steel pipe piles; during concrete pouring construction, carrying out pouring pile concrete pouring construction first, and controlling the position of the steel pipe pile by stabilizing the dead weight of an anchoring plate and the cast-in-place pile concrete; arranging a strain gauge on the lower surface of a frame beam near the shallow foundation, and arranging a reflective mark on the outer side of a structural column; and arranging reinforcing supporting columns between the frame beam and the building floor plate, and arranging a stiff supporting body and an out-pit solidified body on the outer side of an excavation operation groove. The bearing capacity of the shallow foundation can be improved, the influence of foundation reinforcement construction on an existing building is reduced, and the construction difficulty is reduced.
本申请涉及一种现役建筑浅基础后置组合桩加固结构及其施工方法，它包括在浅基础外侧先挖设灌注桩桩孔，再钻设钢管桩桩孔，并在钢管桩桩孔内插设钢管桩；灌注桩与钢管桩的上部设置基础承台，并在钢管桩的上部设置桩芯钢筋笼、反压撑板和连接帽板；混凝土灌注施工时，先进行灌注桩混凝土灌注施工，并通过稳固锚定板及灌注桩混凝土自重控制钢管桩的位置；在浅基础附近框架梁的下表面设置应变计、结构柱的外侧设置反光标；在框架梁与建筑地面板之间设置补强撑柱，在开挖作业槽的外侧设置劲性支护体和坑外固化体。本发明可提升浅基础的承载能力，降低基础加固施工对现役建筑的影响，减小施工难度。
