Description

Foundation pit support structure Technical Field The utility model relates to the technical field of foundation pit support, in particular to a foundation pit support structure. Background Currently, foundation pit excavation is a common construction link in building engineering, underground space development and municipal engineering. Because the stability of the soil mass around the foundation pit directly affects the construction safety, a reliable enclosure structure is required to prevent the soil mass from collapsing, the underground water from leaking and the surrounding buildings from settling. Traditional enclosure modes comprise underground continuous walls, bored piles, steel sheet piles and the like, and the traditional enclosure structure needs to be set up or poured one by one, so that the quick construction requirement is difficult to meet. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model provides a foundation pit support structure, which solves the technical problem that the support structure in the prior art is slower in construction speed. According to the embodiment of the utility model, the following technical scheme is adopted: A foundation pit enclosure comprising: a plurality of steel guard plates; the first connecting structure comprises two steel pipe piles and two mounting seats which are arranged at intervals along the vertical direction, wherein the head ends of two adjacent steel guard plates are arranged on the corresponding mounting seats; the second connecting structure is connected with the tail ends of two adjacent steel guard plates; Wherein, a plurality of steel backplate end to end in proper order encloses and closes and form the enclosure. Preferably, the two mounting seats are provided with mounting grooves which are communicated, the mounting seats at the lower ends are provided with sealing parts, and the steel guard plates are detachably inserted into the mounting grooves. Preferably, the lower end of the steel guard plate is conical. Preferably, the enclosure further comprises a stiffener, the stiffener being a plurality of stiffeners connecting adjacent steel guard plates. Preferably, the reinforcement further comprises: The fixed groove is arranged on the steel guard plate; the fixing rod penetrates through the fixing groove; the two sliding blocks are arranged on the fixed rod at intervals, and the reinforcing rod is rotationally arranged on the sliding blocks. Preferably, the fixing rod is sleeved with a compression spring, and the head end and the tail end of the compression spring are connected with the corresponding sliding blocks. Preferably, the lower end of the steel pipe pile is of a conical structure. Compared with the prior art, the prefabricated steel guard plate structure has the advantages that the prefabricated steel guard plate is adopted, rapid assembly is facilitated, construction efficiency is improved, the steel pipe piles and the mounting seats form rigid joints, the integrity of the enclosure structure is ensured, meanwhile, the arrangement mode of the steel guard plate can be adjusted according to the shape of a foundation pit, and different soil conditions are met.
