pride!The "Belt and Road" largest bridge project in Zhongtie Mountain Bridge is opened to traffic!

June 25,

After 8 years,

The biggest bridge of the “Belt and Road” in Zhongtie Mountain Bridge

Engineering Bangladica Padma Bridge is opened to traffic.

On June 25, 2022, the Padma Bridge was opened to traffic.

The Padma Bridge is located in the lower reaches of the Padma River. The main bridge is 6.15 kilometers of public iron dual -use double -layer steel truss bridge, the upper layer is a four -lane highway, and the lower floor is a single -line railway. The bridge also reserves a pipeline carrying other line equipment such as natural gas and optical cables. As one of the important channels connecting China and Southeast Asia's "Pan -Asian Railway", the Padma Bridge was affectionately called the "Bridge of Dreams" by the Bangladesh people, and it is also the bridge of friendship between China and Meng.

The Padma Bridge uses the European standard full welding structure, ultra -thick plate, and public iron two -purpose steel truss bridge. Zhongtie Mountain Bridge has a production task of 125,800 tons of steel structures of the bridge, consisting of 41 -hole span of 150 meters, and a single hole weighs 3,200 tons.

It is understood that after the Ganges passed through India, they entered the northwest of Bangladesh and ran into the southeast. They were injected into the Bay of Bangladesh in multiple supports. The main one was the Padma River. The Padma River, known as the "water of life" by the Bangladesh people, divided Bangladesh into two, which greatly hindered the coordinated development of northern Bangladesh. Earlier, there was a highway bridge and a railway bridge in the upstream of the Padma River. Ratul, an assistant measurement engineer of the Padma Bridge Project Department, grew up in the village near the Padma River. The distance from the river to the river is no more than one kilometer. He said: "It turned out that I could only take the boat to cross the boat. It took at least two or three hours, and the flood period from July August, which took three or four hours. When it encountered bad weather, the waiting time would be longer. It may be possible for a few days. It may be possible for a few days. ","

In August 2016, at the construction site of the Padma Bridge in Bangladica, the first batch of bridge rods were reported to the prelude to the overall assembly of the bridge.

The journey time after the bridge is shortened to only 10 minutes, which can promote Bangladesh's GDP to increase by 1.5%and benefit the Bangladesh of over half of the population. The bridge also made an important part of the Pan -Asian Railway and the Asian Highway Network, becoming an important part of the "Benne, China, India -Myanmar Economic Corridor".

On June 25, 2022, the Padma Bridge of Bangladesh was opened to traffic. This is a major event in Bangladesh's history and will promote the economic development of Bangladesh into the fast lane. The builders of Zhongtie Mountain Bridge lasted for eight years and used a boutique bridge, Tongxin Bridge, and the development bridge to achieve the "dream bridge" of the Bangladesh people.

Since the signing of manufacturing contracts for the Steel Bridge Steel Truth of Padma Bridge in Bangladesh in September 2014, it lasted for eight years. The problem created another miracle in the history of the world bridge. Especially the innovation breakthrough of ultra -thick welding technology, this is the most difficulty of "stuck neck" in bridge manufacturing. The Padma Bridge with a thickness of more than 70 mm reaches 27.58%of the whole bridge steel plate, far exceeding the same domestic bridge in China proportion. The main truffle node of the bridge adopts the overall welding overall node structure, and all the welding connections are used between the rods.

With the cooperation efforts of the technical personnel, operators and quality inspectors in Zhongtie Mountain Bridge, it has overcome problems such as thick board, large assembly difficulty, small welding space, and welding deformation control. Essence

"At the Padma Bridge construction site, I have worked for 6 years. The Padma Bridge connects the two sides of the river, and connects the hearts of the people of China and Meng. Bridge, Dream Bridge. "Wei Mingxia, chief engineer of the Benka Padma Bridge Project Department of Zhongtai Mountain Bridge, said. Speaking of the future, the only female chief worker on the "Belt and Road" bridge proudly said, "I hope that more countries can share Chinese manufacturing, start from the Padma Bridge, and work together to jointly prosper their dreams."
