IDEA #87CN6K Top panel water tank and manufacturing and construction method thereof

The invention discloses a top panel water tank and a manufacturing and construction method thereof. The top panel water tank comprises a base plate, a wall body and a cover plate; the base plate and the wall body each adopts a half prefabricated structure, and the base plate and the wall body comprises a shell constituted by a prefabricated base plate and a prefabricated wall body and a pour-in-place base plate and a pour-in-place wall body located on the inner side of the prefabricated shell; the shell constituted by the prefabricated base plate and the prefabricated wall body is integrally formed, and the cover plate adopts a total prefabricated structure; and a fixing device for fixing a wall body inner mold and extending inwards is reserved on the inner side of the prefabricated wall body. The manufacturing and construction method of the water tank comprises the following steps that the base plate and the wall body are half prefabricated, and the water tank cover plate is totally prefabricated; and when a top panel is constructed, after the prefabricated base plate-wall body shell is fixed, the wall body inner mold is installed, then wall body and base plate concrete is poured, after the concrete reaches the age, the wall body inner mold is dismounted, the water tank cover plate is lifted, and the position of the water tank cover plate is well adjusted, so that the water tank cover plate can cover the water tank correctly. By adoption of the top panel water tank and the construction method, in-place workers and environment pollution can be reduced, and the construction period can be shortened.
