Construction method of double-type maintenance warehouse for PC component assembly line

The invention belongs to the technical field of PC component assembly line construction, and particularly relates to a construction method of a double-type maintenance warehouse for a PC component assembly line. The construction method includes the following steps: a foundation pit is dug up; steel bar mesh frames are pre-buried, and foundation steel bar frames are placed; positioning tools and all the foundation steel bar frames are fixed, and the level and elevation are adjusted; first-time concrete pouring is conducted; the positioning tools are removed; second-time concrete pouring is conducted; a front warehouse and a rear warehouse are formed; and a mold table storing and taking device is mounted in an area between the front warehouse and the rear warehouse. According to the construction method, labor can be effectively saved, and the construction accuracy demands for vertical columns can be met through one-time construction; and meanwhile, under the premise of ensuring externalsealing of a maintenance environment inside a maintenance kiln, the occupied area of the maintenance warehouse is smaller, and the advantages of high automation degree and low operation threshold areachieved.
