The Yangtze River Daily Da Wuhan Client June 25 (Reporter Gong Ping Correspondent Zhang Jing) "I used to walk on the side of Wuhan Yangtze River Bridge, and I would always think that if one day, one can be built on the Padma River in our country. Such a bridge is fine. "Now, the dream of Professor Banglael Professor of Wuhan University of Science and Technology is realized. On June 25, after nearly eight years of construction, the Pauda Bridge Highway, which was undertaken by the China -China Enterprise Railway Bridge Bureau, was officially opened to traffic.

The Padma River is known as the "water of life" in Bangladesh, like the Yangtze River in China, but it divides the country into southwest and northeast. Due to excessive river channels, turbulent water flow, and frequent floods, the downstream has not been able to build a bridge.

In 2014, the Padma Bridge was officially opened. It is located about 40 kilometers southwest of Daka and across the Padma River. This is also the largest single bridge project with the largest overseas bid in Chinese companies.
This double -layer steel truffle bridge, the upper two -way four -lane road, the design speed is 100 kilometers per hour, the lower layer is a single -line railway, 120 kilometers per hour, the main bridge is 6.15 kilometers long and 21.5 meters wide.
The construction of the bridge is more difficult to imagine.
"The riverbeds of the Padma River are composed of powder sand, with a depth of more than 150 meters. The carrying capacity is extremely low, extremely unstable, and the infrastructure has become the biggest difficulty in the construction of the bridge." Shen Tao, deputy manager of the Padma Bridge project of the China Railway Bridge, introduced. In order to allow the main pier to firmly stand in the water, lay down the most deep steel pipes in the world, and use the world's first pile side pre -pressure technology.

"This is a bridge that adapts to, design, side changes, and side construction. We spent 4 years in the light interpolation test pile." Shen Tao recalled that every time the flood, the main river tank rivers were turbulent, and the construction channel was often recovered. The impact of the stasis, the riverbed has been constantly changing. From 2015 to the present, the pink sand and sand dredge in the project department has reached more than 40 million cubic meters, which can fill 4 West Lakes.
Due to the lack of resources in Bangladesh, the materials, workers, equipment, and materials required by the project must be transported from domestic and cross -ocean to the scene, involving more than 10 international companies, and the project can be called a model of international cooperation. Chinese standards have also been adopted into new international standards for infrastructure.
The builders race against the flood and fight against the epidemic. "When the steel box beams were set up in the later period, there were often people who hired small boats by the river to visit the construction process of the bridge." Shen Tao said.
With the construction of the bridge, the changes are full of earthwork. The builders recalled that when the project was started in 2014, there were only empty rivers and shore beaches by the project station. Now the factory and gas stations are newly built on the Hebei Shore, and the lives of the surrounding residents are getting better and better.

Uzz, a Mumbar employee, who has worked in the project department for two years, has been able to master the operation of the measurement equipment such as the whole station and GPS from a "little white" that knows nothing to measure. In the past, seven people in his family lived in a small house with a total area of less than 40 square meters, and now it has built a bright new house with two floors.
The bridge is opened to traffic. The 21 districts in the southwestern Bangladesh country are connected to the capital Daka. The original seven or eight hours had shortened the river to 10 minutes. The history of residents had completely ended for thousands of years. The bridge has become one of the important traffic fulcrum of the "Belt and Road" construction and an important channel for China and Pan -Asian Railway. After preliminary estimates, the bridge will bring about 1.5%of GDP growth each year to Bangladesh, with a beneficiary of more than 80 million.
