[0038] Working principle of the utility model: The advantage of a mobile spraying device for curing secondary lining concrete of a tunnel in the technical solution is that, by providing a concave main structure with adjustable internal height, when spraying inside the tunnel, the space formed between the water tank 1, the mobile platform 2 and the auxiliary bracket can be temporarily used for other people or vehicles to pass through without delaying the passage inside the tunnel. At the same time, the sprayed aqueous solution will be recycled into the water tank 1 along the spraying assembly on the top of the water tank 1 for aqueous solution collection, and the collected aqueous solution will fall into the mobile platform 2 along the hose for recycling, which saves water resources while not causing water splashing to the channel below the water tank 1.

[0042] The working principle of this utility model:

[0043] Efficient spraying operation: The mobile spraying device adopts a concave main structure design, so that when spraying inside the tunnel, it will not affect the passage, improving the operation efficiency.
