Foundation pit supporting system
The invention provides a foundation pit supporting system, which belongs to the technical field of foundation pit construction, and comprises the following steps: excavating a foundation pit in a construction area by using large-scale mechanical equipment, then fixing and positioning the bottom wall of the foundation pit by using a total station and a precision level gauge, and drawing lines in the fixed point and positioning area by using paint; a projection area, specified on a construction drawing, of the ring beam on the bottom wall of the foundation pit is drawn, piling points of a plurality of positioning piles are evenly positioned in the projection area, on the bottom wall of the foundation pit, of the ring beam through a total station, and the positioning piles are fixed in pile holes; after the cement mortar in the pile hole is hardened, a first layer of ring beam is built in the paint area where the lines are drawn, meanwhile, the ring beam is built layer by layer from bottom to top with the first layer of ring beam as the datum reference till the height required by a construction drawing is reached, and a reinforcing mesh is built on the outer side of the first layer of ring beam; muck is poured into the space between the ring beam and the side wall of the foundation pit through a transport vehicle, and then a road roller is used for compacting. The foundation pit can be stably supported, the foundation is stabilized, and high construction precision is achieved.
本发明提供了一种基坑支撑体系，属于基坑施工技术领域，包括利用大型机械设备在施工区域挖掘基坑，然后使用全站仪、精密水准仪在基坑底壁上定点和定位，并使用油漆在定点和定位区域画线，画出施工图纸上规定的环梁在基坑底壁上的投影区域，使用全站仪在环梁于基坑底壁上的投影区域均匀定位多个定位桩的打桩点，在桩孔内固定定位桩；桩孔内的水泥砂浆变硬后，在画线的油漆区域建造第一层环梁，同时以第一层环梁为基准参照自下而上逐层建造环梁，直至达到施工图纸所要求的高度，在第一层环梁的外侧搭建钢筋网，使用运输车在环梁与基坑侧壁之间倾倒入渣土、再使用压路机压实。本发明能够较为稳定的对基坑进行支撑、稳固地基且具备较高的施工精度。
