The length of the main span ranks first in the world for the same type of bridge! Shenjiancheng Yangtze River Bridge Opened to Traffic
June 25, 2023
“A bridge spans the two banks.”，00 on May 27，It lasted more than 1200 days of continuous struggle.，The Shenjiancheng Yangtze River Bridge in Luzhou City, which was constructed by Sichuan Road and Bridge Engineering Branch of Shudao Group, will be officially opened to traffic.，End the people on both sides of the river.、Boat to cross the pain，Let“Ferry”Become a chapter of history。
Shenjiancheng Yangtze River Bridge is the former river-crossing channel of Hejiang New Town in Luzhou City.（Baisha Yangtze River Bridge），It is one of the important bridge projects in Luzhou City.，The project officially started construction in November 2019.，The total length of the bridge is 1321.7 meters，The deck width is 27.5 meters，The main span is 520 meters。
Highlights of Engineering Design of World-class Project
The main span of the bridge is 520 meters.，The span of the same type of bridge is the first in the world。The steel box girder adopts the flat streamline integral section with the air nozzle participating in the force，Can save steel consumption，At the same time, the integrity of the steel box girder、And that airtightness is bet，Favorable to dehumidification in operation period、Curing。Combined with the topographic conditions of the bridge site area, the south is high and the north is low，The main bridge adopts the tower reasonably.-Pier-Beam consolidation plus one-way longitudinal slope（1.5%）A system of constraints，It can effectively shorten the length of the bridge.，It can also reduce the height of mountain excavation.，Reflect the green environmental protection and economy of bridge design。
Four items“The first time in the country” There are many innovations in technology and methods
For safety、Complete the construction of this super project efficiently，The project team is innovative in technology and management.，Major breakthroughs have been made in many key technologies.，It fills the technical gap in related fields in China.。
For the first time in China, the construction method of bottomless double-wall steel cofferdam with self-adaptive terrain is adopted in the project.、First use of automatic cable threading machine for stay cables、It is the first time to adopt the two-side central cable plane bridge deck crane with standing stay cable.、It is the first time to adopt the low temperature and large tonnage active tension locking closure technology of cable-stayed bridge with tower and beam consolidation system.。
Cancellation of ferry benefits 300000 people
The Shenjiancheng Yangtze River Bridge in Luzhou City is an important bridge project.，Build a revocable bridge、Ding Shiyan、Three ferries in Baisha，Shorten the cross-strait journey from 2 hours to 2 minutes，Eliminate the hidden danger of Yangtze River ferry safety，It is convenient for people across the Straits to travel safely.，Benefiting 300,000 people。
The completion of the bridge will further revitalize the local litchi.、Special agricultural products such as Zhenlong pomelo and scarce tourism resources such as Shenjian Town，Drive the development of industries along the line，Help revitalize the countryside，Comprehensively improve the level of county economic development，To speed up construction“Riverside eco-tourism cities in the upper reaches of the Yangtze River”Lay a solid foundation。Luzhou Shenjiancheng Yangtze River Bridge will further weave the local transportation network.，Effectively promote the integration of Luzhou's transportation network and the development of the Yangtze River Economic Zone，Strengthen the interconnection with the adjacent areas of Chongqing、Co-construction and sharing，Push“East wing”Take advantage of the situation to break through，Help Luzhou speed up its integration into the Chengdu-Chongqing economic circle。
