Problems solved by technology

[0002] Traditional sprinkling and covering maintenance take up a lot of people, and the maintenance effect is related to the responsibility of the maintenance personnel. In addition, small components are generally thin-walled structures, and the hydration channel and temperature shrinkage channel of concrete components are short. Dry shrinkage cracks and temperature shrinkage cracks caused by excessive heat dissipation of concrete components, so water storage and maintenance can greatly reduce maintenance labor costs and maintenance material costs, and the maintenance quality is high; the effect of spray maintenance is better, but the disadvantage is that more configurations are required The maintenance frame is used to ensure that all the maintenance components are wetted for maintenance, which occupies a large space and the cost of maintenance equipment is high

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] A water storage and maintenance process for small prefabricated components, such as figure 1 As shown, the construction process includes the following steps:

[0025] S1. Preparation work: select the template, check and screen the shape and size of the template, clean the template with oxalic acid after the screening, and apply the release agent evenly in the template. There are no small oil droplets under it to ensure the cleaning and protection of th...

Abstract

The invention relates to the technical field of concrete prefabricated components, in particular to a small prefabricated part water storage and maintenance process. The small prefabricated part waterstorage and maintenance process comprises the following steps: preparing, concrete mixing, test piece preparation, concrete vibrating, plastering, spraying and maintaining, water storing and maintaining, component storing and unqualified prefabricated part processing. De-moulded concrete is integrally soaked into a water storage pool, the maintained component is completely isolated from air, andthe component is soaked into water to hydrate and dissipate uniformly, so that the probability that the small component has dry shrinkage cracks and warm-shrinkage cracks is very low, and maintainingquality of the concrete component is ensured; in the water storage pool, a constructor does not need to watch maintenance, so that labor cost is reduced. The prefabricated part obtained by the maintenance process is high in qualification rate, is good in quality and is low in labor cost.
