Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit technology for utility tunnels, specifically to a protective structure for the sidewalls of deep foundation pits for utility tunnels. Background Technology

[0002] Pipe galleries, also known as corridors for pipelines, are where many pipelines in chemical and related factories are concentrated and arranged along the outside of the equipment or factory buildings. They are usually located in the air, supported by brackets, forming a corridor-like shape. A few pipe galleries are located underground.

[0003] Existing technology publication CN211849485U discloses a reinforced protection structure for the sidewall of a foundation pit. The locking unit includes a locking wheel, a fixing plate, a locking shaft, a spring, and a locking plate. The locking wheel is fixedly connected to the outer arc surface of the front end of a screw. The fixing plate is fixedly connected to the outer side of a front support plate. The locking shaft is slidably connected to a circular hole in the middle of the fixing plate. A locking plate is fixedly connected to the lower end of the locking shaft. The upper end of the spring is fixedly connected to the lower surface of the fixing plate, and the lower end of the spring is fixedly connected to the upper end of the locking plate. The locking plate cooperates with the locking wheel to lock and fix the screw, preventing movement. The structure also includes a T-pin. The vertical part of the T-pin is slidably connected to a through hole at the front end of the chassis. The vertical part of the T-pin passes through a circular hole at the rear end of a connecting rod, connecting and fixing the connecting rod and the chassis, while also facilitating adjustment. The plate is fixed to the ground at the outer edge of the pit, ensuring the lower side of the reinforcing plate is flush against the pit's sidewall. Rotating the crank handle drives a gear via a connecting shaft, which in turn moves two racks in opposite directions. These racks then move corresponding fixed rods, adjusting the reinforcing plate's tilt angle to align with the pit's sidewall. Pulling the locking shaft upwards causes a locking plate to move upwards, disengaging from the locking wheel. Rotating the turntable, via a screw, moves a moving block forward. This moving block, through the connecting rod, housing, and fixed rod, moves the reinforcing plate forward, strengthening the pit's sidewall. Releasing the locking shaft allows the locking plate to move downwards under spring pressure, inserting into the locking wheel's tooth groove and securing the screw. This pit sidewall reinforcement structure allows for adjustable plate tilt angles, is suitable for pit slopes of varying gradients, and offers simple operation and robust protection.

[0004] However, in the existing technology CN211849485U patent, the adjustment and protection capabilities of a foundation pit sidewall reinforcement and protection structure are poor. As a result, in the actual use of the foundation pit sidewall reinforcement and protection structure, it is impossible to adjust the reinforcement and protection structure to a suitable angle position as needed, which is not convenient for the foundation pit sidewall to be strongly protected and affects the protection effect of the foundation pit sidewall reinforcement and protection structure.
