At 20:30 on August 30th in the Maldives, on the 21st Century Maritime Silk Road, a grand opening ceremony was held in support of the China-Maldives Friendship Bridge, marking the opening of the China-Maldives Friendship Bridge. Maldivian President Yaming and Wang Xiaotao, the representative of the Chinese government and the Director of the National Development Cooperation Agency, jointly inaugurated the opening of the bridge. Tian Daoming, secretary of the Party Committee of BRDI, attended the opening ceremony and witnessed this historic moment with the representatives of the Chinese and Malaysian governments, the participating members of the bridge, and the ordinary people of the Maldives.
The assistance to the Maldives China-Maldives Friendship Bridge is a key demonstration project of the “Belt and Road Initiative”. The Bridge Group will undertake the bridge survey and construction drawing design and provide full technical services.
The China-Maldives Friendship Bridge adopts Chinese standards, Chinese regulations, Chinese technology and Chinese management. The arched structure of the main bridge of the bridge reflects the classic elements of traditional Chinese bridges. The three V-shaped piers are like seagulls flying in the sea, blending with the local marine environment. The landscape project of the bridgehead incorporates rich Islamic architectural elements. The bridge has a total length of 2,000 meters and a sea-crossing bridge of 1,390 meters. The main bridge is 760 meters long and is a six-span composite beam V-shaped steel structure.
As the first sea-crossing bridge in the Indian Ocean, it is also the first large-scale cross-sea bridge built on coral reefs. Coral reef geology and high sea salt environment have great influence on bridge structure and materials, which brings many challenges to the bridge construction.
According to Tan Guohong, head of the Maldives project of the Daqiaoyuan Group, in view of the characteristics of light coral density, porosity and strong variation of coral reef limestone, the “variable section steel pipe composite pile foundation” scheme was creatively proposed on the main pier of the main bridge. The bridge foundation design problem of the gushing area and coral reef geological conditions has been successfully solved; the superstructure of the main bridge adopts the “concrete V-structure + superimposed beam” hybrid beam scheme, which ensures the long-span and large-span forces are reasonable and avoids The influence of swell on the hoisting of the main beam of the large section reduces the construction difficulty and guarantees the project construction period; in order to realize the service life of the bridge for 100 years, the design uses the marine high-performance concrete and the basic anti-corrosion to increase the thickness of the concrete protective layer. Measures, at the same time, for different structural parts, the design principle of additional anti-corrosion measures such as weathering steel + coating for epoxy steel bars and steel beams is added to meet the durability requirements of bridges.
The China-Malaysia Friendship Bridge is a cross-sea super-large bridge jointly agreed by the two heads of state during the visit of Chinese President Xi Jinping in 2014. The two countries jointly named the bridge "China-Maldives Friendship Bridge". The completion of the bridge ended the history of the lack of land connection between the Maldives capital Malé and the airport. Tourists can quickly reach the airport from Male by land, effectively driving the economic development of the Greater Malé region. At the same time, the China-Maldives Friendship Bridge has created In the undisturbed environment of the deep ocean in the world and the precedent for the construction of super-large bridges under the geological conditions of coral reefs, facing a series of world problems, the Bridge Group has handed over a beautiful answer, once again showing the world the strength of China's bridge construction and The level has realized the long-standing "Bridge Dream" of the Maldives in the Thousand Islands!
