Document Type and Number:
WIPO Patent Application WO/2022/156255
Kind Code:
A1
Abstract:
Disclosed in the present invention is a double-deck multi-span bridge construction method. According to the double-deck bridge construction method of the present invention, construction is carried out by using a method of dissembling a support jig frame in a graded and span-separated mode, an upper chord jig frame and a lower chord jig frame can be used in a recycle manner, and construction costs are reduced. In addition, a construction period of building the support jig frame is shortened, and other construction operations can be synchronously carried out on a span in which the jig frame is disassembled, for example, fire retardant coating construction can be carried out on a mounted bridge deck after the jig frame is dissembled, and the construction period of a double-deck multi-span bridge is effectively shortened. Additionally, according to the double-deck multi-span bridge construction method in embodiments of the present invention, the upper chord jig frame and the lower chord jig frame are disassembled in a graded manner, thereby ensuring that a bridge structure can be smoothly and safely transitioned to a designed stress state.
