Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction and maintenance equipment, in particular to a tunnel spraying maintenance vehicle. Background Technique

[0002] With the vigorous development of traffic construction, tunnels, as an indispensable structure for crossing obstacles in traffic construction, are affected by factors such as geological conditions, climate, ventilation, and construction methods during the tunneling process. The humidity in the tunnel environment changes abnormally. After the secondary lining construction, the shrinkage deformation caused by the premature evaporation of moisture on the lining surface, and even surface dry shrinkage cracks, not only seriously affect the durability and integrity of the concrete, but also reduce the appearance quality of the lining surface. Therefore, it is necessary to spray the surface.

[0003] In the traditional construction process, most tunnel maintenance adopts the maintenance measure of manually holding a water spray gun to spray water. Its maintenance effect is directly related to the subjectivity of the workers, and manual spraying is time-consuming and laborious, often resulting in untimely and incomplete maintenance, which is likely to cause cracks in the secondary lining concrete structure and seriously affect the service life of the tunnel. Therefore, people have developed and applied tunnel lining maintenance trolleys.

[0004] Through applied research, it is found that although the tunnel lining maintenance trolley can improve the tunnel spraying maintenance effect, the structure of the tunnel lining maintenance trolley is complex and the manufacturing cost is high. In addition, when constructing in a tunnel with a high dust concentration, workers are prone to pneumoconiosis to varying degrees, reducing the tunnel construction efficiency. During the construction process, it is necessary to spray and dust in the tunnel. Due to the inflexible operation of the tunnel lining maintenance trolley, it is not conducive to applying spraying and dust reduction work in the tunnel. Therefore, it is necessary to design a tunnel spraying maintenance vehicle that can be applied to both tunnel spraying maintenance and spraying and dust reduction work in the tunnel. Summary of the Invention

[0005] The purpose of the utility model is to provide a tunnel spraying maintenance vehicle, which has a simple structure, flexible walking and operation, and can be applied to both tunnel spraying maintenance and spraying and dust reduction work in the tunnel.
