Description

Supporting device for deep foundation pit excavation Technical Field The utility model relates to the field of supporting equipment, in particular to a supporting device for deep foundation pit excavation. Background In the deep foundation pit engineering construction process, the stability of a foundation pit supporting structure is directly related to the construction safety and the safety of surrounding buildings. The traditional foundation pit supporting mode generally adopts structures such as steel sheet piles, concrete filling piles or underground continuous walls. The existing supporting device is fixed by welding or bolts in a connecting mode, so that the installation efficiency is low, the perpendicularity and the overall stability of the baffle are difficult to ensure, deflection or deformation is easy to occur under the action of soil pressure, and the supporting effect is influenced. Therefore, a deep foundation pit supporting device with simple structure, convenient installation and high stability is needed to meet the requirements of efficient and safe construction of modern foundation pit engineering. Disclosure of utility model The utility model aims to provide a supporting device for deep foundation pit excavation, which aims to solve the defects in the technology. In order to achieve the purpose, the supporting device for deep foundation pit excavation comprises a bottom plate and a baffle, wherein a C-shaped socket with a C-shaped structure is formed in the outer wall of one end of the top of the bottom plate, the bottom of the baffle is inserted into the inner wall of the C-shaped socket, the inner wall of the C-shaped socket is in clearance fit with the outer wall of the baffle, a limiting plate is fixedly arranged on the inner wall of the C-shaped socket, an inserting hole is formed in the outer wall of the limiting plate, an inserting column which is vertically upwards is fixedly arranged on the outer wall of the top of the bottom plate, the outer wall profile of the inserting column is matched with the inner wall profile of the inserting hole, top plates are arranged at the tops of the two baffles, butt joint blocks are fixedly arranged on the outer walls of the two ends of the bottom of the top plates, and the outer wall profile of the butt joint blocks is matched with the top inner wall profile of the baffle.
