Technical Field

[0001] The utility model relates to the technical field of tunnel engineering, in particular to a foldable combined walkway plate special for tunnel engineering. Background Art

[0002] Tunnel engineering refers to the construction of buildings underground or in the mountains to lay railways or build roads for motor vehicles to pass. It is widely used in transportation, water conservancy, mining and other aspects. The construction of tunnel engineering involves a variety of technologies and methods, including drilling and blasting, shield method, New Austrian Tunneling Method, etc.

[0003] The foldable combined walkway plate for tunnel engineering is a walking platform specially designed for tunnel construction or maintenance. This walkway plate has the characteristics of folding and combination. It is composed of two or more metal plates connected by links and can adapt to different construction environments and needs. When the foldable combined walkway plate for tunnel engineering is used, one of the metal plates is usually driven to rotate, so as to unfold the foldable combined walkway plate for tunnel engineering, and then the connected foldable combined walkway plate for tunnel engineering is connected with the external support equipment, and finally the external support equipment is connected to the corresponding work station installation and docking, so as to realize the installation and fixation of the foldable combined walkway plate for tunnel engineering;

[0004] During the use of the existing foldable combined walkway panels dedicated to tunnel engineering, although they can drive the metal plates to rotate, thereby unfolding the foldable combined walkway panels dedicated to tunnel engineering, in subsequent work, the connections between the metal plates are usually exposed, which will cause the hinges to be damaged and reduce the service life of the foldable combined walkway panels dedicated to tunnel engineering. At the same time, when the foldable combined walkway panels dedicated to tunnel engineering are folded, they also need to be tied and fixed by ropes and other equipment to prevent the walkway panels from automatically unfolding during subsequent mobile transportation. The operation is more troublesome and also reduces work efficiency. For this reason, we propose a foldable combined walkway panel dedicated to tunnel engineering. Utility Model Content
