Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, specifically a foundation pit support structure for smart water conservancy projects. Background Technology

[0002] In water conservancy projects, the main purpose of supporting the foundation pit is to ensure the safety and stability of the foundation pit during construction and to meet the functional requirements of the project.

[0003] Chinese patent discloses a foundation pit support structure, publication number CN217629951U, including a protective plate, a bottom plate, a reinforcing plate, and a support assembly. The protective plate and the bottom plate are angled together. The reinforcing plate is positioned near the connection point between the protective plate and the bottom plate and is connected to both the protective plate and the bottom plate to support the bottom of the protective plate. The support assembly is also connected to both the protective plate and the bottom plate, with its connection point to the protective plate near the top of the protective plate. Because the reinforcing plate and the support assembly can simultaneously support the bottom and top of the protective plate, the support is more uniform and the supporting force is greater, resulting in a better support effect for the foundation pit support structure.

[0004] However, it still has the following drawbacks: While the device can simultaneously support the lower and upper parts of the protective plate using reinforcing plates and support components, it is not convenient to adjust the relative angle between the protective plate and the bottom plate, and it is not suitable for supporting foundation pits with different inclinations. Therefore, we propose a foundation pit support structure for smart water conservancy projects to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a foundation pit support structure for smart water conservancy projects to solve the problems mentioned in the background art.

[0009] The connecting part includes a support rod, a connecting block is hinged to the left end of the support rod, and a mounting plate is hinged to the bottom end of the support rod.

[0010] A further improvement is that the adjustment part further includes a first positioning bolt, a mounting block, a stud, a second positioning bolt, a worm gear, and a worm wheel. The top end of the stud is hinged to the right end face of the mounting block, and the outer surface of the bottom end of the stud extends into the interior of the mounting cylinder and is threadedly connected to the inner wall of the mounting cylinder. By setting the stud and the mounting cylinder, the overall length of the stud and the mounting cylinder can be adjusted by adjusting the relative position of the stud and the mounting cylinder.

[0011] A further improvement is that an annular groove is formed on the outer surface of the mounting cylinder, and the inner wall of the mounting seat extends into the annular groove and is rotatably connected to the inner wall of the mounting cylinder through a first bearing. The bottom end of the mounting seat is hinged to the top surface of the mating block. By setting the mounting seat, the mounting cylinder is supported, and the mounting cylinder can be rotated to adjust the relative position of the stud and the mounting cylinder.

By setting the first positioning bolt and the second positioning bolt, it is convenient to position the mounting block and the mating block.

[0014] A further improvement is that both the worm gear and the worm are located inside the mounting base. The worm gear is fixedly sleeved on the outer surface of the bottom end of the mounting cylinder. The outer surface of the front end of the worm passes through the inner wall of the mounting base and extends to the front of the mounting base through the second bearing. By setting the worm gear and the worm, the mounting cylinder is driven to rotate by rotating the worm. At the same time, the self-locking property of the worm gear and the worm keeps the mounting cylinder stable.

[0015] A further improvement is that the connecting part also includes a second ground nail and a wall nail. The outer surface of the connecting block has a through hole. The outer surface of the left end of the wall nail slides through the interior of the connecting block and the right end face of the support plate and extends to the left side of the support plate.

The support position of the device can be adjusted according to the depth of the foundation pit. Rotating the worm gear drives the worm wheel to rotate, adjusting the relative position of the stud and the installation cylinder, and changing the length of the stud and the installation cylinder to adjust the tilt angle of the support plate. This facilitates support for different types of foundation pits. The self-locking property of the worm wheel and worm gear ensures the relative stability of the installation cylinder, improving the stability of the device. By setting wall nails, which are inserted obliquely into the foundation pit wall, the soil exerts pressure on the outer surface of the wall nails when the support plate rotates, improving the stability of the support plate. By setting up a second ground nail, a connecting block, a support rod, and an installation plate, the connecting block connects adjacent support plates, and the support rod supports the connecting block, improving the stability of the connection between adjacent support plates.
