Background
For the common plate rib type anchor rod retaining wall or lattice type anchor rod retaining wall at present, rib columns and lattices are of reinforced concrete structures, the retaining wall is usually required to be supported along with excavation in design files, the excavation height does not exceed the distance between anchor rods every time, and a supporting structure needs to be constructed in time after excavation. However, in the actual construction process, the construction unit often can not excavate and in time carry out the supporting construction according to the design requirement, and there is the following reason mainly:
