Chongqing Dongshuimen Yangtze River BridgeOverview
The Chongqing Dongshuimen Yangtze River Bridge is located in the city of Chongqing and connects the Yuzhong district with the Nan’an district. Official opening to traffic was in 2014.
The bridge acts as the urban secondary trunk road and starts from Tushan Road, Nan’an district, crosses the Yangtze River, leads through the Huguang Guild Hall and finally ends at Shan’xi Road, Yuzhong district.
It is a combined bridge including upper and lower decks. The main bridge is a double tower and single cable plane cable-stayed steel truss girder bridge with a main span of 520 m, a deck width of 21 m and an overall length of 1’000 m.
In 2013, mageba installed several TENSA-MODULAR expansion joints of type LR3 and LR8 as well as TENSA-GRIP RS single gap joints for the Chongqing Dongshuimen Yangtze River Bridge.
TENSA®MODULAR expansion joints allow free movements in all directions and rotations about every axis. The largest joints delivered, type LR8, can accommodate movements of up to 640 mm.
TENSA-GRIP RS single gap joints can facilitate movements of up to 80 mm. The joints consist of robust steel edge profiles and replaceable elastomeric sealing profiles, which ensure long-lasting watertightness. The drainage of the joints is accomplished by the drainage system of the bridge deck.
