Introduction of Fuzhou Pushang Bridge?

Fuzhou Pushang Bridge is located in Fuzhou, crossing the south port of Minjiang River (Wulong River) and connecting Pushang Avenue in Cangshan District and Nanyu Town in Minhou County 1 17 County Road. Including the approach bridge, the total length is about 3 kilometers. This bridge is the first municipal highway bridge on the Wulong River in Fuzhou, and its opening to traffic has opened a new chapter for Fuzhou's urban expansion.

Characteristic interest

Pushang Bridge uses cables to lift the main girder at multiple points, which transfers the dead load of the main girder and other loads such as automobiles to the tower column and then to the foundation through the tower column foundation. Because the tower column, cable and girder form a stable triangle, the structural stiffness of Pushang Bridge is greater, and its wind resistance is much better than that of suspension bridge.

Bridge information

The project starts from Hongwan Road in Jinshan New District, goes west along Pushang Road, crosses the Third Ring Road, crosses the Wulong River, and reaches Shang Jie (University Town) to connect with Wulongjiang Avenue. The total length of Pushang Bridge and its wiring project is 3083.42 meters, in which the main bridge length of Pushang Bridge is 1.464 meters, and the approach bridge length of the east bank approach bridge is 670438+0.4 meters. The connection length of the west bank approach bridge is 948.706 meters. The total length of the bridge in this project is 227 1.9 meters (excluding the length of ramp bridges A and B of the East Third Ring Road-Pushang Interchange and the Third Ring Road at the intersection), and the bridge deck width is 33.5 meters. According to the project, K0+000 ~ K0+670.7 14 is the East Coast Third Ring Road-Pushang Interchange, which will be constructed in two phases. This project only includes the main bridge (east approach bridge), ramp bridges A and B and the third ring road. K0+670.714 ~ K2+134.714 is the main bridge of Pushang Bridge, and K2+466.438+04 ~ K3+083.42 is the approach bridge and wiring project of West Bank Bridge. Take the street (University Town) to Wulongjiang Avenue.

In addition, the approach bridge on the west bank of Pushang Bridge will cross the planned Jiang Bin Road, then cross Wulongjiang Avenue, and connect with National Highway 3 16. The intersection of the West Bank and Wulongjiang Avenue will also be a long-term interchange. It is also known that Pushang Bridge is the first three-tower cable-stayed bridge in China. Due to the special hydrogeological conditions at the location of Pushang Bridge, the main bridge of the bridge is divided into navigable main bridge and non-navigable main bridge. The main bridge without navigation holes will adopt a concrete continuous box girder bridge with a span of 50 meters, while the main bridge with navigation holes will adopt a three-tower single-cable prestressed concrete cable-stayed bridge on the basis of ordinary continuous beams. The main cable-stayed bridge will be equipped with three pylons in the longitudinal direction, two pylons in the upstream and downstream direction of each pylon and six pylons in the * * * direction. The bridge tower is 27 meters above the bridge deck. The sidewalk of Pushang Bridge will be paved with colored tiles and equipped with night landscape lighting facilities.

meaning

When the bridge is completed, it will be the "Southwest Gate" of the banyan tree.

Pushang Bridge is an important traffic project connecting Fuzhou Second Ring Road, Third Ring Road, University Town, National Highway 3 16 and National Highway 324. It is an important node to open the exit passage in the southwest of Fuzhou, and it is also an important link between the urban road system and the peripheral road network and trunk lines.

After the completion of Pushang Bridge, the traffic in Fuzhou University Town, Jinshan New District and the central city will be more convenient, which will open up the important traffic out of the city in southwest Fuzhou and become the "southwest gate" of Rongcheng's external traffic.

Experts predict that after the bridge is completed and opened to traffic, Pushang Bridge can divert about one-third of the traffic flow of Nandamen, effectively alleviating the current traffic congestion of Nandamen in Fuzhou.
