Description

TECHNICAL FIELD

[0001] The utility model relates to tunnel maintenance technical field, especially a kind of open cut tunnel side wall automatic spraying maintenance device. BACKGROUND

[0002] With the advancement of urbanization, the application of municipal open cut tunnel becomes increasingly widespread. The main body of open cut tunnel is mostly reinforced concrete structure, and the maintenance construction of concrete structure is particularly crucial to the quality, durability and safety of open cut tunnel. Especially for mass concrete structure such as side wall and middle wall, the maintenance process is crucial. Through timely maintenance measures, the strength of concrete can be quickly improved, and the generation of surface cracks can be effectively reduced, thereby enhancing the performance of the entire structure.

[0003] The traditional tunnel secondary lining concrete maintenance method mainly relies on manual, covering moisture-retaining material or fog cannon vehicle for spraying maintenance. However, manual maintenance is inefficient and ineffective. The method of covering moisture-retaining material with a small amount of manual watering is not ideal. In actual operation, the covering material is difficult to closely adhere to the side wall, resulting in poor moisture-retaining effect and rapid water loss, thereby affecting the quality of maintenance. In addition, this method is also accompanied by problems such as large material loss, frequent replacement and high cost, and manual maintenance is tedious and time-consuming. Due to the complex shape of the side wall, insufficient or excessive maintenance may occur. The fog cannon vehicle is expensive and has relatively high operation and maintenance costs. The spraying maintenance effect of the fog cannon vehicle is uneven, and the concrete maintenance effect is difficult to guarantee. At the same time, the frequent entry and exit of the fog cannon vehicle into the tunnel will cause serious interference to other construction machinery and operations. SUMMARY
