It is expected to be opened to traffic in October!Another "world -class" bridge in Guizhou South is hot construction

At 2 am on July 28th, the Guida Expressway Guiding Interchange Line No. 20 Ganxi Special Bridge No. 20 pier on the right side of the side spanned the concrete pouring section. Make major progress in line engineering.

On May 31st, Guihuang Expressway was officially opened throughout the board. As the biggest difficulty of the Ganxi Special Bridge of Guihuang high -speed Guiding interoperability connection project, its construction progress has always attracted the attention of citizens. understand situation.

"The bridge deck at the main position of Ganxi Special Bridge 20, we now enter the final sprint stage. The Guizhou connection line of the Guihuang Expressway is 14.9 kilometers. Driving the local economic development, we will also complete the Ganxi Special Bridge on a high quality, high -efficiency and safely. "Zhang Rui, manager of Shanghai Yuantong Company Guihuang Expressway 16th standard project, introduced.

It is understood that the Ganxi Special Bridge has a total length of 1220m and a main span length of 300m. The north -north shore is set up with a bridge. It is one of the controlling projects with the largest difficulty and the highest safety risk level in Guihuang Expressway. The first attempts of the above -mentioned consecutively rigid bridges span the world's first in the form of the same type of bridge. It is difficult to build in the mountainous area of ​​the project in Guizhou, with poor construction conditions, prone to geological disasters, and high construction risks; the main pier of the bridge is 25-55m deeply artificially digging piles, high construction risks, safety management The difficulty; its main pier is a large -volume concrete engineering, with construction organization and technical difficulty; the highest main pier in the bridge is 129m high, and the construction of an arched diagonal legs in an empty triangle area is difficult; Quality control is difficult, safety risks, technical challenges are strong, and the master span is 300m prestressed concrete box beam. During the construction process, bridge linear control is difficult.

All kinds of difficulties and problems require the project construction to overcome difficulties and advance in order. To this end, the project construction party Shanghai Yuantong Company Guihuang Sixteen standards have also been thoroughly arranged and deployed.

Chen Bo, the chief engineer of Guihuang Sixteen standards of Shanghai Yuantong Company, said: "We have carried out a detailed technical intercourse and safety convergence of the technical solution, including safety and quality solutions to ensure the quality of each process and meet the requirements of quality engineering. The quality and quality of the Ganxi Bridge is the lead in China. According to our established plan, it is completed in August, and the middle span is completed in Around September 20, and it takes one month to perform bridge for a month. Construction of the surface, opened to traffic by October. "

It is understood that with the successful cross -crossing section of the first cross -section, there is only a middle crossing the dragon in the whole bridge. After the full bridge is connected, the rapid road of Xinba Town to Guiding County will be opened to traffic. By then, Xinba Town will The distance from Guiding will be shortened from 26 kilometers to 14 kilometers, and the drive will be shortened from 60 minutes to 20 minutes.
