Description

Technical Field

[0001] The utility model relates to the technical field of tunnel maintenance operation equipment, in particular to an automatic spraying maintenance trolley. Background Art

[0002] Tunnel lining refers to the masonry and covering of the walls and top of the tunnel to enhance the structural stability and safety of the tunnel. Tunnel lining is usually constructed with concrete to protect the tunnel from geological conditions, water pressure and other external factors. After the concrete is poured in the tunnel and the formwork is removed, the concrete needs to be sprayed with water for curing. If the spraying and curing is not carried out in time, cracks are likely to appear when the concrete shrinks. Therefore, it is often necessary to use a spray curing trolley to spray water on the concrete in the tunnel. The spray curing trolley is a sprinkler device that sprays water on the concrete after the tunnel lining to ensure the curing of the concrete and reduce concrete cracking.

[0003] Common spray maintenance trolleys usually have construction workers standing on them with water pipes. As the vehicle moves forward, the construction workers use water pipes to pump water from the water tank to spray water on the concrete. Due to the large cross-section of the tunnel lining, especially the side arch, it is difficult to operate during maintenance operations. Simple manual watering alone usually cannot meet the maintenance requirements of high-strength lining construction, and manual watering is more random, which can easily lead to uneven and incomplete watering, so that the maintenance quality cannot be effectively guaranteed. Therefore, the applicant provides an automatic spray maintenance trolley to solve the problems raised in the above background technology. Utility Model Content
