Description

High-strength foundation pit supporting structure Technical Field The utility model relates to the technical field of construction tools, in particular to a high-strength foundation pit supporting structure. Background The high-strength foundation pit supporting structure can bear external loads such as soil pressure, water pressure and the like, and engineering safety is ensured. In foundation pit engineering, the main function of the supporting structure is to prevent soil collapse and deformation and ensure the stability and safety of the engineering main structure. Meanwhile, the underground water level can be effectively controlled, the occurrence of water trouble is prevented, and important influences are generated on the construction progress and the construction cost. Urban construction rapidly develops, and underground space is widely and widely utilized along with the acceleration of the urban process. The construction of projects such as high-rise buildings, subways, underground passages and the like enables the scale of foundation pit projects to be continuously enlarged, and the requirements on supporting structures are also higher and higher. In some areas with complex geological conditions, such as soft soil areas, karst areas and the like, the difficulty of foundation pit support is greater. These areas require more advanced and more reliable support structures to ensure engineering safety. Through retrieval, the patent document (the authorized bulletin number is CN 219825289U) comprises a guard plate, a first support plate and a second support plate, wherein a plurality of first support plates and second support plates are arranged on the rear side surface of the guard plate, a plurality of first support plates and a plurality of second support plates are arranged on the rear side surface of the guard plate, a mountain-shaped protruding block is integrally formed on the left side surface of the guard plate, the right side surface of the guard plate is sunken leftwards to form a mountain-shaped groove, each guard plate is mutually clamped and connected through the protruding block and the groove, the cross section of the first support plate is in an L-shaped structure, the second support plate is in a T-shaped structure, and a first fixing hole, a second fixing hole and a third fixing hole are formed on the surface of the first support plate.
