The overpass bridge spanning the North Ring Railway, part of the Dongwen North Road in the Dongli Lake area, completed its rotation construction on Nov 20.
The North Ring Railway is a freight railway and an important corridor for the China-Europe freight trains and logistics routes linking the sea port.
To minimize the impact on the railway, a "rotating bridge" construction method was adopted to construct the overpass.
The "rotating bridge" has a span of 156 meters, consisting of two rotating beams, each weighing approximately 11,000 tons.
The construction method for the "rotating bridge" involves first casting the bridge parallel to the railway on temporary supports and then rotating it into place.
This is the first dual large-span rotating bridge over a railway on a major urban road in Tianjin.
To ensure the progress and safety of on-site construction and ensure the safe operation of the existing railways, China Railway Beijing Group Co., Ltd. has provided support and services for the construction of the project.
After completion, Dongwen North Road project will greatly improve the transportation level of the Dongli Lake area, effectively ease traffic congestion, improve the traffic efficiency between the Dongli Lake area, the airport area, and the urban area, and help promote regional economic construction and the development of cultural and tourism industries.
