Document Type and Number:
WIPO Patent Application WO/2021/078310
Kind Code:
A1
Abstract:
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: (1) removing cantilever beams (12, 13); (2) removing lateral pier support systems (34) and loading same onto a truck; (3) removing outer-side main beam sections (11-1) connected to lateral pier support systems (34) and loading same onto a truck; (4) removing, horizontally displacing, and lowering a main beam middle section (11-2) connected to the main pier support system (2); (5) hoisting, lowering, and laying flat a main truss system (25), and loading same onto a truck; and (6) removing a main pier vertical support system (24) and a sleeper beam (33). The present method for removal allows for rapid removal of a large-scale temporary support system from within the area of pre-fabricated small box girders following completion of pre-fabricated small box girder construction, and obviates the need for the operating space used by such equipment as traditional, heavy-duty truck cranes and crawler cranes.
