Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete column maintenance, in particular to a column spray maintenance device. Background Art

[0002] Bridge components usually have two construction processes: cast-in-place and prefabrication. Compared with cast-in-place bridge components, prefabricated components have the advantages of low cost, fast construction speed, small impact of concrete shrinkage on bridge structure, and standardized production. Prefabricated bridge components include columns, box beams, T beams, etc., and their production steps are usually casting, demoulding and curing. Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. If the surrounding environment does not have such conditions, the concrete needs to be cured manually.

[0003] At present, natural curing methods such as direct watering and spraying concrete curing agent are often used for prefabricated bridge components. When direct watering curing is used, due to the high height of prefabricated columns and the rapid evaporation of curing water, it is necessary to keep the spray gun on the top of the column and the spray pipe on the bottom of the column for a long time (generally 7 to 14 days) to spray the top and side walls of the column regularly. Affected by the height of the column, the curing water at the bottom cannot be sprayed on the side walls of the column, resulting in a waste of labor and water resources. When the film moisturizing curing method is used, there are often phenomena such as untimely wrapping, loose wrapping, loose fixing, failure due to strong winds, and difficulty in operating high piers, which leads to interruption or termination of column curing, thereby affecting the curing effect of the column, and even causing concrete weakness and cracking, which directly affects the service life of the concrete. Therefore, it is of great research value to design a set of spray curing devices for prefabricated columns to provide them with a better spray curing environment. Utility Model Content
