Abstract

The invention relates to the technical field of underground traffic engineering construction, and provides a porous frame bridge and an assembly construction method thereof. Block factory prefabrication is adopted, and synchronously conducted with excavation of a foundation pit. First, after upper and lower segments of a single prefabricated segment are assembled to form closed prefabricated segments, a large-segment frame bridge is formed by multi-direction longitudinal splicing of the multiple closed prefabricated segments, and longitudinal prestress is stretched; and in the splicing formingprocess of the whole large-segment frame bridge, site formwork erection, steel bar binding, concrete pouring and other processes are not needed, the construction progress is greatly accelerated, theinterference of construction vehicles and machines and tools on surrounding traffic is reduced to the maximum extent, dust and noise pollution to surrounding areas is lowered, and great economic and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of underground traffic engineering construction, and more specifically, to a porous frame bridge and an assembly construction method thereof. Background technique [0002] At present, the construction method of open-cut and cast-in-place is generally adopted for shallow-buried integral porous frame bridges in cities. The advantages of the open-cut method are that the construction technology is simple, fast, economical and the stress conditions of the main structure are good. However, it greatly interferes with the surrounding environment and urban life, blocks traffic for a long time, and has large noise and vibration. In addition, the open cut and cast-in-place method requires a large number of on-site formwork, steel bar binding and welding, and concrete on-site pouring. slow. [0003] In order to overcome the limitation that the open-cut method has a great impact on the ground, some projects adopt the c...
