[0001] The invention relates to the technical field of tunnel lining, in particular to a tunnel lining maintenance device. Background Art

[0002] Tunnel lining refers to a permanent structure that supports and maintains the long-term stability and durability of the tunnel. Its functions are: to support and maintain the stability of the tunnel; to maintain the space required for train operation; to prevent weathering of the surrounding rock; to eliminate the influence of groundwater, etc. Therefore, the tunnel lining must have sufficient strength, durability, and certain anti-freeze, anti-seepage and anti-erosion properties. The tunnel lining is mainly composed of arch rings, side walls, inverts and bottom plates. In order to drain the water in the tunnel, drainage ditches (central drainage ditches or side ditches) are also set up in the tunnel.

[0003] After tunnel excavation, construction workers need to spray concrete on the inner wall of the tunnel in time to form the tunnel lining. Tunnel lining has multiple functions. Lining is not only used to support the excavated free surface of the tunnel, but also can be used to level the uneven parts formed after the excavation of the inner wall of the tunnel. Furthermore, lining can be used for waterproofing and other functions. After the lining is completed, the tunnel with completed lining is manually watered for maintenance.
