Description

Technical Field

[0001] The present application relates to the field of precast concrete component maintenance, and in particular to a precast concrete component water circulation maintenance pool. Background Art

[0002] After demoulding, the internal moisture of the concrete precast parts will be lost quickly, which will affect the hydration heat reaction of the cement and further affect the strength of the concrete. Putting the precast parts into the water curing tank for curing can ensure that there is enough moisture for the hydration heat reaction of the cement, thereby ensuring the strength of the concrete.

[0003] Moreover, concrete precast parts produced at high temperatures are prone to cracks after demoulding due to the rapid loss of internal moisture. The water curing tank can effectively prevent the occurrence of such cracks by maintaining a certain humidity and temperature, ensuring the integrity and durability of the precast parts.

[0004] Therefore, the main function of the precast concrete water curing tank is to ensure the quality and durability of the precast concrete parts. The maintenance of precast concrete parts is an important link. Water circulation curing technology has gradually received attention, and the precast concrete parts are placed in the water curing tank.

[0005] Usually, water curing ponds are designed to be open-air so that precast concrete parts can be hoisted into the water curing ponds, which causes dust and impurities to easily enter the water curing ponds, polluting the water quality and making it inconvenient for water recycling. Therefore, designing a water curing pond that can automatically filter the water in the water curing pond is an urgent problem to be solved. Summary of the invention

[0006] In order to automatically recycle the water in the water curing tank, the water in the water curing tank is filtered and treated, and the present application provides a precast concrete part water circulation curing tank.
