Description

Technical Field

[0001] The present application relates to the field of road operation and maintenance, and specifically to an assembled highway tunnel arched manned maintenance platform vehicle that does not occupy the road. Background Art

[0002] At present, in order to repair lamps and fans in highway tunnels, as well as detect and deal with surface cracks, water leakage and other defects within the arch area, it is necessary to close part of the road traffic in the tunnel, or even the entire tunnel traffic, and use aerial work vehicles or lifting vehicles to occupy the road for construction before carrying out related operations. In this way, the entire highway traffic will also have a bottleneck effect at the tunnel maintenance point, which seriously restricts the economic benefits of the tunnel and leads to traffic jams, vehicle delays and other problems.

[0003] What's more, due to the large contrast in brightness between the inside and outside of the tunnel, a "black hole effect" will occur at the entrance of the highway tunnel. When vehicles outside the tunnel enter the tunnel, the driver's eyes will not be able to see the scene in front of them for a few seconds, and the scene in front of them is completely black. The tunnel is temporarily blocked for traffic, especially near the entrance. When work vehicles are arranged to occupy the road for construction, passing vehicles cannot see the scene in front of them due to the "black hole effect" and are likely to collide with work vehicles and personnel working at the tunnel entrance, causing traffic accidents. If construction warning signs are set up, long diversion lines are also needed to divert traffic, which will increase the workload of maintenance personnel.

[0004] In order to reduce traffic congestion caused by tunnel maintenance and the secondary traffic accidents that may be caused by it, and to reduce the workload of highway tunnel maintenance personnel, it is necessary to develop a tunnel construction and maintenance platform vehicle that does not occupy the road and does not affect traffic.
