Flat laying production of a fixed die table: as shown in fig. 1, the mold platform is flatly paved in a workshop of a factory building and is fixed, the mold assembly and pouring are finished, the single-layer plane maintenance is carried out, and the energy consumption is high; finished products are hoisted in situ one by one, so that the occupied area is large, the basic investment is large, the production efficiency is low, and the personnel demand is large.

Flat die assembly line production: as shown in fig. 2, the mold table is placed on the rail, the production station personnel are not moved, and the mold table moves on the rail and is lifted to a centralized point for maintenance through complicated mechanical devices. The method has high requirements on factory buildings and infrastructure, large investment and long construction period; the production equipment investment is high, and the installation period is long; the electric control equipment is complex, and the requirement of operators is high; the occupied area of the production area is large; products produced in different periods are maintained in the same maintenance area, so that the energy consumption is high, and the product quality is not easy to guarantee; the mold table can only move in a plane and only move in a specified route, so that the space is not reasonably utilized, and the production efficiency is low. Single-line flow production, once any link goes wrong, the whole production line can form blockage; the material organization, the finished product transportation line is too long, the efficiency is low, and the waste is serious; and cannot be operated in a crossed manner.

Therefore, the defects of the existing concrete prefabricated part production mode are as follows: the permanent facilities are added in the fixed factory building, so that the investment of basic construction is huge, the construction period is long, the moving is not easy, the transportation is limited, the long-distance project cannot be made, and the environment is not protected.
