However, the tunnels are too long and the construction projects are large, so the feed pipes are often blocked and difficult to clear, which greatly affects the construction process.
[0003] Most of the existing transport carts are manpower carts, including wheels, storage troughs and handles. The wheels are rotatably connected to the bottom of the storage trough, and the handle is welded to one side of the storage trough. When in use, the material is generally placed in the storage trough, and then the handle is pushed so that the wheel drives the storage trough to move along the tunnel direction, and the material in the storage trough is transported to the construction site, and then the handle is lifted to pour the material in the storage trough into the material collection area.
