Description

Technical Field

[0001] The utility model relates to the technical field of trenchless repair, in particular to a fixing bracket used for trenchless repair. Background Art

[0002] When performing trenchless repair, a pit needs to be dug on the ground first to place the trenchless repair device, and then a person needs to go down into the pit to perform the operation, and place the trenchless repair device into the pipe to be repaired for repair. When the person goes down into the pit to perform the operation, if the surrounding soil layer collapses, it will cause certain dangers to the operators. At the same time, the manual operation also increases the operating strength of the construction workers. The existing fixed bracket for trenchless repair is not easy to be applied to pits of different depths for operation. Therefore, a fixed bracket for trenchless repair is needed for operation.

By arranging lifting ears that are easy to hoist on each component and inserting the connecting column into the connecting hole, it is convenient to fix the position of the retaining plate, and it is also convenient to quickly install and disassemble. The inner wall of the retaining board is inclined inward from top to bottom, and the bottom thickness of the retaining board is greater than the top thickness. Under the condition of effectively preventing soil collapse, compared with setting the inner wall as a vertical surface, it saves production costs, reduces the weight of the retaining board, and facilitates transportation.
