[0002] During the construction of municipal roads and buildings, rainwater pipes and sewage pipes need to be laid. When laying rainwater pipes and sewage pipes, trenches need to be opened at the laying location, and the rainwater pipes and sewage pipes need to be laid in the trenches. After laying, the trenches need to be backfilled with sand.

[0003] In the existing pipeline construction process, it is necessary to use machinery to excavate the trench. In order to avoid trench collapse during excavation and construction, it is necessary to slope the trench side walls during trench excavation. Slope excavation will increase the amount of earthwork excavated in the trench, affecting construction efficiency. At the same time, if the slope is not standardized or the soil layer is loose, collapse may still occur during excavation or construction, reducing the safety during construction. To solve the above problems, the present application proposes an anti-collapse support frame for trench construction. Utility Model Content
