Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to a cantilever lining curing device. Background Art

[0002] Curing lining concrete is a critical step in ensuring its long-term stability and durability. Proper humidity and temperature control during curing promotes the full hydration reaction of cement, enhancing the concrete's strength and crack resistance. Furthermore, good curing reduces surface cracks caused by rapid evaporation and prevents damage to the concrete's internal structure, thereby extending the project's service life. Therefore, curing lining concrete is not only crucial to structural safety but also a key consideration for economic efficiency and environmental sustainability.

[0003] A tunnel maintenance trolley disclosed in the Chinese invention patent application disclosure CN216342194U belongs to the field of tunnel maintenance technology. The tunnel maintenance trolley includes a maintenance component. The maintenance component includes a mobile body, a support rod, an electric push rod, an arc tube, a nozzle, a water tank, a water pump and a telescopic hose. In the above implementation process, the mobile body is moved inside the tunnel, and then the arc tube and several nozzles are opposite to the concrete in the tunnel. Then, the water inside the water tank is sucked by the water pump, and the water sucked by the water pump is discharged into the inside of the arc tube through the telescopic hose, and then sprayed out from several nozzles to water the concrete. Then, the electric push rod drives the support rod to repeatedly rotate left and right, thereby driving the arc tube and several nozzles to repeatedly rotate left and right.

[0004] This technical solution can evenly water the concrete, replacing manual watering, greatly reducing the labor intensity of workers, and the watering is relatively uniform, which is very convenient. However, due to the influence of the pumping equipment parked near the lining trolley, or the stored small formwork and materials, it is not convenient to use the common tunnel lining maintenance trolley for an adjacent pouring section before the lining trolley moves forward.
