Tunnel inner surface lining concrete atomization curing maintenance vehicle for tunnel construction

Abstract

The invention provides a tunnel inner surface lining concrete atomization curing maintenance vehicle for tunnel construction. The vehicle structurally comprises a maintenance vehicle head, maintenancevehicle wheels, a frame, a water tank, a lock plate, a tunnel inner surface atomization maintenance device, wherein the maintenance vehicle head is fixedly connected with the frame, the maintenance vehicle wheels are arranged at the bottom of the maintenance vehicle head and are mechanically connected with the maintenance vehicle head, and the bottom of the water tank is fixedly connected to thetop end of the frame in an electric welding mode. According to the vehicle, a pulverization atomization curing mechanism is jacked through a supporting pressing adjusting spreading mechanism to form acomplete form of water spray, when the maintenance vehicle passes through a tunnel at a constant speed in a straight mode, water mist sprayed out through the tunnel inner surface atomization maintenance device can impact a wall surface, due to the fact that the weak impact force of the water mist and the impact stress is dispersed, even if lining concrete in the inner wall of the tunnel is partially solidified, no damage is caused, and comprehensive maintenance can be carried out without monitoring relying on light in the whole process.

Description

technical field [0001] The invention belongs to the field of concrete, and more specifically relates to a maintenance vehicle for atomizing and maintaining the inner lining of the tunnel for tunnel construction. Background technique [0002] In the construction of mountain tunnels, it is necessary to support the interior during excavation to reduce the loosening of surrounding rocks and prevent landslides. Usually, reinforced concrete and other materials are used to build permanent support structures. The most common type is block lining. High-pressure grouting concrete lining, and in order to prevent the concrete from cracking during the solidification process, it needs to be watered and cured in time. [0003] Based on the above description, the inventors found that the existing tunnel lining concrete atomization maintenance vehicle for tunnel construction mainly has the following deficiencies, such as: [0004] Since the watering maintenance basically directly impacts th...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a tunnel lining concrete atomization maintenance vehicle for tunnel construction, to solve the problem that the existing sprinkler maintenance basically directly impacts the water flow on the tunnel wall through the water pipe, and then needs to wait until the lining concrete is solidified. To a certain extent, maintenance can be carried out, but in the mountain tunnel, it is dark and can only be gradually solidified through air circulation, and all the lighting inside the tunnel needs to rely on lights, the concrete lining in the middle position will solidify faster than before and after The two stages are slower, and the solidification speed of the mixed contact is also gradually transitioned. If the maintenance is not carried out in time, the wall surface will crack easily, which will easily lead to the fact that the solidification strength in some areas cannot meet the requirements during the maintenance process, resulting in The problem of wall damage
