Description

Technical Field

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

[0002] Whenever the tunnel project's engineering support or secondary lining construction is in progress, there will be a problem with concrete curing. Concrete curing refers to covering or sprinkling water on the concrete surface after the final setting of the concrete building is completed. The purpose is to avoid the problem of water shortage in the concrete during the hardening process. Once there is no time to replenish water and a large amount of water is lacking, the concrete will easily crack and the strength of the entire concrete structure will drop significantly. Therefore, sprinkling water during the curing process of concrete is essential. The curing of shotcrete and secondary lining concrete cannot be carried out by conventional covering and curing because the concrete curing surface is suspended and the arch height is large.
