The longest continuous beam crossing the dragon on the longest ends of the Jingjing Railway

China Transport Broadcasting June 19th News (Correspondent Zhang Zhiyong Mao Deren) At 3 am on June 19, the longest overpass of the Jingjing Railway Jianghan Canal Bridge (48+80+48) undertaken by the China Railway Bridge Bureau (48+80+48) Mi continuous beams cross the dragon smoothly.

It is understood that the total length of the Jianghan Canal Bridge is 16.22 kilometers in length, located in Chuandian Town, Jingzhou District, of which 303 to No. 306 is a continuous beam pier, which spans provincial highway 271. Continuous beams, in order to adopt a single -box single -room, height, and cross -sectional straight abdomen, the top of the box beam is 12.6 meters wide, and the prestressed dual -line continuous box beams with one -connection and three -hole are across the S271 provincial road with large traffic. The closed -hanging basket suspension construction, one -sided hanging basket hanging 10 sections, high safety risks.

In order to ensure the successful completion of the cross -crossing nodes, the construction team of the China Railway Bridge Bureau has organized a special technical meeting many times to clarify the construction processes and control points of each link, and strictly implement the work and process control of the plan. During the process, actively overcome high temperature, epidemic, and unfavorable factors. By implementing the leadership class system, various inspection visa systems, and full construction materials and equipment, the construction efficiency is effectively improved. At the same time, the continuous beaming point was used as the welcoming point of the Jingjing project, and passed the inspection of various superior units to get unanimous praise.

During the construction of the bridge, the project construction team resolutely implemented the concept of "start -up is the decisive battle, the start is sprinting" and "steady, good, good, fast, fast and fast" In the early stage of planning, organized personnel to run and advance, and quickly entered the "accelerated track" of construction production. Since March, the project team has taken the opportunity to "fight for first -class and continuously build new skills" labor competition, anchor the goal of construction plan, optimize the process method, and adopt measures to "work outfitting technology, technology insurance quality" measures. Science science, science science Arrange resources reasonably, do a good job of processing, and quickly promote project construction. Up to now, the project pile foundation has completed 4502, Chengtai has completed 551, with 547 pier bodies, 144 榀 in the prefabrication of the box beam, and 65 榀 榀.

The newly -built Jingmen to Jingzhou Railway is a key regional transportation network key project in the national “13th Five -Year Plan” comprehensive transportation system plan. The design speed is 350 kilometers per hour. After the Jingjing Railway was completed and opened to traffic, Jingzhou and Jingmen have only taken 20 minutes.
