Secondly, according to the total number of bridge beams, the total construction time of precast beams and the pouring, formwork removal and on-site maintenance time of a precast beam (the time from the pouring site to the beam storage area), the number of precast formwork groups, the number of precast beam bases and the area of precast pouring site are determined.
Third, design the land area of steel bar processing, concrete mixing and cement, sand and cement yard next to the pouring site.
Fourthly, according to the size of the beam, determine the hoisting mode of the beam and the land area required for hoisting the beam.
