Description

Technical Field

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

[0002] Tunnel linings are permanent structures that support and maintain the long-term stability and durability of tunnels. Their 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 linings must possess sufficient strength, durability, and resistance to freezing, seepage, and erosion. Tunnel lining maintenance organizations are primarily responsible for the maintenance and inspection of tunnel linings to ensure tunnel safety and reliability.

[0003] For example, a tunnel lining maintenance mechanism disclosed in Chinese patent CN220769484U realizes the adjustment of the upper nozzle and the nozzle in the height direction by setting an electric push rod, so that the upper nozzle and the nozzle can adapt to various tunnels. By setting an adjustable electric push rod, the position of the round block can be adjusted, and then the movement range of the upper nozzle and the nozzle can be adjusted to achieve water spraying maintenance of the lining concrete. By using the slider nested guide rail, the movement of the side wall water spray assembly is made more stable.

[0004] For this structure, although the nozzle can be adjusted to spray, the mechanism is large in size and inconvenient to use. Therefore, we propose a foldable spraying mechanism to make maintenance more convenient for a tunnel lining maintenance mechanism. Utility Model Content
