Technical Field

[0001] This utility model relates to the field of foundation pit support technology, specifically a foundation pit support and protection frame for water conservancy engineering construction. Background Technology

[0002] Currently, existing foundation pit support mechanisms for water conservancy engineering construction can achieve good disassembly, making it easy to disassemble and store. This reduces the floor space required for storage, improves space utilization, and enhances the practicality of the foundation pit support mechanism.

[0003] For example, CN218843123U discloses a foundation pit support mechanism for building construction, including a base plate. A ground bolt is fixedly connected to the bottom end of the base plate. A matching groove is formed at the top of the base plate, and a matching block is movably connected inside the matching groove. A vertical plate is fixedly connected to the top of the matching block. A right-angle plate is movably connected to one side of the vertical plate, and a fixing bolt is movably connected to one side of the right-angle plate. A threaded groove is formed at the top of the base plate, and a sliding groove is formed inside the vertical plate, with a sliding block movably connected inside the sliding groove. However, such a foundation pit support mechanism for building construction is inconvenient for quick assembly and disassembly of the vertical plate. Furthermore, the ground bolt is firmly inserted into the soil, and the flat surface of the base plate makes it inconvenient to use lifting equipment to lift and remove the base plate.

[0004] As can be seen from the solutions disclosed in the existing patent documents, it is inconvenient to quickly disassemble and assemble the upright plate, and the ground bolts are firmly inserted into the soil. The surface of the bottom plate is flat, making it inconvenient to use lifting equipment to lift and pull out the bottom plate. Therefore, it is necessary to improve the existing technology.
