At 12 am on September 4, Beijing time, it was managed by the China Railway Bridge Institute for survey and design. The sources of national friendship have a long -term testimony.

The Eighth Bridge of Mengzhong Friendship is the eighth bridge project in my country to assist Bangladesh. The project is located about 5 kilometers east of Pirojpur in Barisar, southern Bayela, with a total length of 3.0 kilometers in the project line, including about 1.5 kilometers of a bridge. The "PC Project Management" model of the Chinese agency project is adopted.

Rigorous

Adjust the bridge site to guard the safety of the residents

"It is really difficult in the past few years! But no matter how difficult it is, it is worth it!" On the day of opening, Xiao Haizhu, the current chief engineer of the China Railway Bridge Survey and Design Institute.

For a long time, people on both sides of the coast of Kucha River have been dependent on the ferry. Not only are they inefficient, but they are very affected by the season. Whenever the rainy season, the wind and waves are fierce, and the shipwreck accidents are frequent.

How to build a "safety bridge" on cross -strait residents crossing the river? In May 2016, Academician Gao Zongyu led the full -scale on -site team to go to Bangladesh for preliminary technical survey.

According to existing technical information, the Bayi Bridge of Mengzhong Friendship Bridge has been basically drawn. However, when the team arrived at the actual bridge, it was accidentally found that the only ferry route on both sides of the strait residents happened to form an oblique sex with the bridge line -this means that if the original bridge is maintained, once the construction is started, the ferry will cross the river. Avoid the construction site, the river flow was turbulent, and the ferry car mixed, there were great hidden safety hazards.

"In any case, we must seek truth from facts! Never take life safety adventures!" The team decided unanimously. To this end, the project team has launched various tasks. On the one hand, the bridge is located at hydrology, geological conditions and local actual traffic needs, and optimizes the bridge site; on the other hand, collect materials, write reports, and reflect relevant issues to domestic superior management departments in time. In just two days, the application for changes and the optimization plan was also adopted.

Flexible design

Create Crescent Moon Suspension Bridge

Knowing that China was going to build a bridge, officials from the RHD of the Highway Bureau of the Bangladesh Owners immediately found the design team of the China Railway Bridge Institute and proposed to build the bridge into "the arc as the suspension of crescents as beautiful as crescent."

It is not difficult to build a modern cable bridge, but it is difficult to match the local bridge management and maintenance level, and the later high -amount maintenance costs need to be fully guaranteed. Suitable for building suspension bridges, otherwise it will generate huge costs.

Considering this, Sun Yingjie, then the head of the bridge design (the general manager of the current China Railway Bridge Tunnel Technology Company), divergent ideas, retain Mengfang's favorite arc, make a seven -cross -continuous rigidity plan, and use the Islamic -style dome arch. The facade of the architectural shape and the transformation of the main beam and the arc -shaped groove bridge pier is integrated. It not only solves the maintenance problem, but is also closely combined with the local landscape. In addition, in order to reflect the friendship between China and Meng and the two places, the Islamic element pattern was also designed on the bridge pier and landscape guardrail, and the "Chinese knot" shape was designed on the bridgehead.

"Baru! (Mei Ji!)" In September 2016, when Sun Yingjie put the effect map in front of the Mengfang representative, the representative of the Mengfang thumbs up, marking the successful completion of the survey measurement and deepening design.

"One important part of promoting China from the" Bridge Great Power "to the 'Jianqiao Powerful Power' is to deeply integrate into the global technology chain, industrial chain, innovation chain, and value chain. Continue 'walk in' '', continue to make technical breakthroughs in the high -end value chain, and continue to shape the brand image of Chinese design and Chinese quality to enhance the comprehensive competitiveness and influence of 'China Bridge' in the world. "China Railway Bridge Academy Deputy General Manager Chen Dezhu said.
