Detailed Description
The invention is further illustrated by the following figures and examples.
If a certain embodiment of the airport extension project underground continuous wall project is multi-surface and wide, the distance between a construction point and the point is as far as one to two thousand meters, but each construction point is not suitable for arranging a fixed operation platform bound by a reinforcement cage, and even if the point can be arranged, the fixed binding platform needs to be repeatedly disassembled and reassembled for many times, so that the labor, time and material are wasted, and the cost is high. Along with the propulsion of engineering progress, the distance between the site of tying up the steel reinforcement cage and the construction site can be more and more far away, and the crawler crane is used for lifting and carrying the large-scale steel reinforcement cage, and not only is the efficiency low, but also the large-scale steel reinforcement cage is carried with the crawler crane, and the in-process easily jolts, causes the major safety and the quality accident that the steel reinforcement cage looses the frame. At the moment, the movable reinforcement cage platform with the traction device is needed to realize convenient, rapid and safe reinforcement cage carrying and transferring.
