[0002] The traditional cast-in-place cover plate of the central ditch of a highway tunnel is cast with plywood during pouring, and a φ42 steel pipe is used at the bottom for support. A large number of steel pipe racks of different lengths are required for formwork support before each pouring. After the steel pipe rack is erected, the plywood is assembled. After the overall assembly is completed, the concrete can be poured. When removing the formwork, the operator needs to enter the drainage ditch, remove the steel pipe brackets one by one and drag them out of the ditch, and then remove the formwork and drag it out. The overall process is: bracket erection → formwork installation and reinforcement → concrete pouring → bracket removal → formwork removal. The process is complicated, and the installation and removal workload is large. In addition, the central ditch of the tunnel is small in size, only 1m wide and 0.6m high. When performing dismantling operations inside, there are the following risks: small space and poor viewing conditions; limited space for operators to move around, low removal and installation efficiency, time-consuming and labor-intensive; complicated bracket erection process, large safety hazards; difficult to clean up internal debris after demolding, affecting the overall quality of the ditch.
