Jianning Road West Crossing project starts from the north at the junction of Xingpu Road and Jiangbei Avenue in Jiangbei New District, laying along the direction of Xingpu Road, crossing Puzhu Road, Linpu Railway, Pu Bin Road, in the form of a tunnel with the planning of the Hengjiang Avenue to set up an underground intercommunication, and then in the form of a tunnel across the Yangtze River to the south bank and then lay along the existing Jianning Road, and finally in front of the west side of the Jinchuan River Road.
Jiangbei section of Jianning Road West Crossing
What is the progress of the construction of the upper crossing of Puju Road?
The actual scout is here!
Jianning West Road Crossing Project (Phase I) iron project 2 standard section north from Puzhu Road, south to the intersection of Xingpu Road and Pu Bin Road, "the section is 1,409 meters long, the mainline bridge a total of 15 joints." Shen Dianfeng, deputy chief engineer of the project, said that the first link is a cast-in-suspension girder construction across Puzhu Road, the second to the sixth link is a prefabricated box girder across the Linpu Railway, the seventh to the fifteenth link is a cast-in-suspension girder, the bridge is equipped with on- and off-ramps on both sides.
At present, the substructure construction of the first to the ninth, the fifteenth and the on- and off-ramp bridges has been completed, and the superstructure construction of the cast-in-suspension girder across Puzhu Road is underway.
"The most difficult part of the section is the construction across the Puju road, which is a two-way eight-lane road with heavy traffic.In order to protect the safety of pedestrians and traffic under the bridge, the intelligent hanging basket with fully closed pocket protection program."It's a good idea," Shen Dianfeng said.
Suspended girders on the upper span Puzhu section are constructed with intelligent hanging baskets. Through the synchronized walking system, the hanging baskets on both sides achieve synchronized forward movement towards the middle of the road, and after each movement, the next girder section will be constructed and observation points will be laid on the girder surface and monitored in real time so as to ensure that there will be almost no error in the final merging. It is understood that the entire cross section needs to be symmetrically poured with concrete 8 times, and then 1 time when the main span is closed.
"At present, we have completed the installation of hanging baskets on both sides of the suspension beams, and all the work is progressing in an orderly manner.The closing of the suspended beams is expected to be completed in May next year."It's a good idea," Shen Dianfeng said.
The blue part is the intelligent hanging basket system and the yellow part is the full protection multi-channel platform.
The Jianning West Road Crossing project is located between the Yangtze River Bridge and the Yangzi River Tunnel, about 1.8 kilometers from the upstream Dinghuaimen Yangtze River Tunnel and about 2.4 kilometers from the downstream Yangtze River Bridge.
As an important part of Nanjing's "high speed road system", the Jianning West Road river crossing will effectively alleviate the traffic pressure on the trunk line across the river after completion, and enhance the convenience of the core area of the Jiangbei New Area and the Jiangnan Gulou riverfront connection.As the closest river crossing to the Nanjing Yangtze River Bridge, theIt will then take only 15 minutes to drive from Jiangbei Avenue to Central Gate.
