[0002] Deep foundation pit support refers to the support measures taken in construction of deep foundation pits within a specific depth range to prevent pit wall collapse and soil settlement, ensuring construction safety and building stability. The design of deep foundation pit retaining structures includes determining the shape, depth, and required bearing capacity of the pit, and designing a reliable and effective retaining structure. In this process, various factors such as soil properties, water level, and environmental influences must be comprehensively considered to ensure that the retaining structure can safely withstand the required external and internal forces.

[0003] A search revealed Chinese Patent Publication No. CN222206372U, which discloses a deep foundation pit support structure, belonging to the field of deep foundation pit support technology. The structure includes a base, with a support plate hinged to the left end of the base. An adjustable support plate is slidably connected to the left side of the support plate. A stop plate is fixed to the top of the adjustable support plate. An adjustment component for adjusting the height of the adjustable support plate is provided inside the support plate. Multiple fixing cones are fixed to the left side and lower end of the stop plate. Two bottom support rods and two top support rods are hinged to the left and right ends of the top of the base. The adjustment component includes two connecting blocks. This deep foundation pit support structure, through the adjustment component, allows for adjustment of the height of the adjustable support plate, enabling adjustments according to different foundation pit depths. This effectively enhances the practicality of the support structure, eliminates the need for manual adjustment by operators, effectively reduces the tediousness of adjustment, improves convenience, and reduces the workload of operators. However, when supporting deep foundation pits, diagonal braces are used for support. However, the support points between the diagonal braces and the support plate need to be fixed and adjusted according to the inclination angle and depth of the foundation pit. Existing diagonal braces require multiple people to disassemble multiple bolts to complete the adjustment of the support points, which is very time-consuming and labor-intensive. Therefore, a deep foundation pit support structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a deep foundation pit support structure, which aims to improve the problem that the existing technology requires multiple people to operate the diagonal bracing and disassemble multiple bolts to complete the adjustment of the support point.

[0023] The left and right sides of the adjusting plate are fixedly connected to the reinforcing plates, and the rear sides of the two reinforcing plates are fixedly connected to the front side of the support plate.

[0024] The above technical solution uses a reinforcing plate to connect the adjusting plate and the support plate, ensuring their integration.

[0025] As a further description of the above technical solution:

[0026] Both of the reinforcing plates have screw holes on their front sides, and bolts are threaded onto the inner walls of the screw holes.

[0027] The above technical solution involves reinforcing the plate with bolts to ensure its stability on the support plate.
