A method for removal of a temporary support system for a road bridge pre-fabricated small box girder-type concealed bent cap, and equipment therefor. The removal method comprises the following steps: removing cantilever beams; removing lateral pier support systems and loading same onto a truck; removing outer-side main beam sections connected to lateral pier support systems and loading same onto a truck; removing, horizontally displacing, and lowering a main beam middle section connected to the main pier support system; hoisting, lowering, and laying flat a main truss system, and loading same onto a truck; and removing a main pier vertical support system and a pad beam.

A construction module for a structure, comprising: a formwork member that includes a base, a pair of parallel side walls that extend upwardly from the base, and a pair of parallel end walls. The base, the side walls and the end walls define a cavity for reinforcement and concrete. A reinforcement member includes an upper portion and a lower portion. When the reinforcement member is located in the cavity and concrete fills the cavity, the lower portion of the reinforcement member and the concrete define an elongate beam.
