Problems solved by technology
[0003] Due to the poor firmness of the soil during the excavation of the foundation pit, it is generally necessary to use the foundation pit support structure to support the side wall of the foundation pit during construction. In the process of foundation pit support, it is generally necessary to set up different foundation pit support devices according to different slopes, which is not universal

The invention relates to a foundation pit supporting structure and supporting equipment for a building. The foundation pit supporting structure comprises a fixed base and movable bases located on thetwo sides of the fixed base and movably matching with the fixed base, supporting plates are hinged to the movable bases and connected with an opening and closing control mechanism installed on the fixed base through an angle adjusting mechanism connected with the supporting plate, the angle adjusting mechanism comprises movable pieces which are connected with the opening and closing control mechanism and hinged to the supporting plates, clamping plates are hinged to the sides, facing the supporting plates, of the movable pieces, embedded grooves are formed in the sides, facing the movable pieces, of the supporting plates, and a plurality of clamping grooves matching with the clamping plates in a clamped mode are formed in the inner walls of the embedded grooves. The arranged opening and closing control mechanism controls the distance between the two supporting plates to be adjusted, supporting of foundation pits with different widths is achieved, the arranged clamping plates are clamped in the different clamping grooves so as to change the angles of the supporting plates, and the foundation pits with different gradients can be supported.
Description
technical field [0001] The invention relates to the technical field related to construction, in particular to a foundation pit support structure and support equipment for construction. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. For those with deep excavation and nearby buildings, the foundation pit wall support method, shotcrete retaining wall method, and large foundation pit even adopt methods such as underground diaphragm wall and column-type bored pile interlocking...
