Construction Method of the East Third Ring Road Elevated Expressway in Xuzhou City
1.1 At present, the traditional method of prefabricating hollow slab beams is mainly to make templates of corresponding specifications, fix them after assembly and molding, and pour concrete in the templates. As the inner diameter of the hollow slab beam with large span is relatively large, the formwork can be easily removed and reused for cyclic pouring after the completion of the curing period, which is satisfactory. However, problems are encountered in the construction of small span precast hollow slab beams. Because of its small inner diameter, it is difficult to remove the concrete after the completion of the curing period, and the formwork cannot be reused. If the number of precast slab beams is very small, it is acceptable, but it is particularly wasteful to prefabricate a large number of hollow slab beams. The cost is greatly increased, and the construction progress is slow.
