Jin Jianren Express Road across the Minjiang Bridge enters the bridge pavement stage

On September 27, the reporter saw in the China Wuye Construction Technology Industrial Park that the first batch of steel structure components with a total weight of about 1,420 tons are being loaded slowly, and they are shipped to Jinjian Ren Expressway across the Minjiang Bridge construction site for follow -up. Operation. This marks this stage of the world's widest bridge to the world with 86.7 meters.

The bridge has three "the most" in the world

Jin Jianren Expressway Cross -Minjiang Bridge is located at a position of about 450 meters downstream at the lower reaches of Bai Guo Street. The bridge is 963 meters in length and 513 meters in the main bridge. The main bridge adopts the structure of the unique tower dual cable -faced cable bridge structure. The total height of Sota is about 173 meters, which is a semi -closed steel box beam structure. The standard width of the main beam of the bridge is 64 meters. The widest is located in the main tower beam section with a width of 86.7 meters.

"The Minjiang Bridge, as an important node across the Minjiang River, has the world's widest bridge bridge, the world's highest tilt bridge tower, and the world's largest leaflet asymmetric curve surface. , Unique shape, novel structure, and difficult construction technology. "The relevant person in charge of the project construction unit Chengdu Communications Group said.

The Minjiang Special Bridge adopts the first -level highway and the urban expressway standard, and sets up the two -way 10 lanes of the "Main Six Supplements and Four". The design speed is 100 kilometers per hour. In terms of design, the bridge is cleverly connected to the bridge surface and water surface through the structure of elegant and space changes, like a silver ribbon. The front of the bridge is like the letter "E", which means the "Belt and Road", showing the era of the era of harmony and harmony between the thousand -year -old culture and modern civilization; The wind of the future.

"No Trace Bridge" enters the scene and start paving

"In order to ensure the node target of the first batch of steel components in September, we have overcome the impact of high temperature, electricity limit, and epidemic conditions, open the" epidemic bubble "mode, and polish the components in a closed -loop production method to maximize the production of production. The influence of. "Wang Yan, the person in charge of the production of steel structure of the Garden of China Five Metallurgical Technology Industry, said that the Qiangjiang Bridge has a unique shape and a new type of structure. Within 3 mm. In the workshop, the reporter saw that hundreds of technical welded workers and advanced board unit automatic welding systems "alternated" to continuously improve the welding accuracy and ensure that the "no trace bridge body" was leave the factory on time.

"The total steel volume of the bridge reaches 43,000 tons and the steel structure is 513 meters. After the first batch of steel components entered the field, it marked the main pavement stage of the bridge into the bridge surface. Push from the east and west sides of the Minjiang River, with a maximum span of 238 meters. "Liu Liming, the project manager of Jinjian Ren Crossing the Minjiang Bridge of China Wuye Group, China Wuye Group, said.

After the completion of Jin Jianren Expressway where the bridge is located, it will effectively shorten the distance from urban areas to Huaizhou New Town. At the same time, Huaizhou New Town, Jianzhou New Town, and Airport New City will be connected to another traffic road to Tianfu International Airport. Construction of Shuangcheng Economic Circle in Chengdu -Chongqing area.
