Description

Technical Field

[0001] This utility model relates to the field of tunnel lining maintenance technology, specifically a track spraying device for tunnel lining maintenance. Background Technology

[0002] Tunnel lining refers to the permanent structure that supports and maintains the long-term stability and durability of a tunnel. Its functions include: supporting and maintaining tunnel stability; maintaining the space required for train operation; preventing weathering of the surrounding rock; and mitigating the effects of groundwater. Therefore, tunnel lining must possess sufficient strength, durability, and certain resistance to freezing, seepage, and erosion. Tunnel lining mainly consists of the arch ring, sidewalls, invert arch, and floor slab. Drainage ditches are also installed inside the tunnel to drain water. During curing, the tunnel lining requires water spraying.

[0003] Currently, the existing technology for maintaining tunnel linings typically involves manual spraying of water using handheld water hoses. However, the height of the tunnel lining makes effective spraying difficult, the limited spraying area results in low efficiency, and automated repeated spraying is not feasible, leading to poor maintenance results.

[0004] Therefore, we propose a track spraying device for tunnel lining maintenance to solve the above problems. Utility Model Content
