At 10 o'clock on September 12, with the final crane of the last steel box beam of Xiang'an Bridge (Xiamen Second East Channel), it marked the inner side and Xiang'an side of Xiang'an Bridge Island, which are processed by the China Shipbuilding Bridge Heavy Industry Company. Connect closely, the main bridge of Xiang'an Bridge was successful.

The Xiang'an Bridge is an important part of the "one vertical" of the "six vertical and ten horizontal" planning highway network in Fujian Province. Bridge. After completion, the bridge will effectively promote the integrated development of Xiamen Island, and further improve the integrated transportation hub of the Haixi Economic Zone Road Network and Xiamen City Road Network and build a comprehensive transportation hub on the southeast coast and the strait. Active promotion role.

The total length of the Xiang'an Bridge is 12.371 kilometers, of which the cross -sea bridge is about 4.5 kilometers. The steel box beam weighs 37,600 tons of steel box beams controlled by China Shipbuilding Heavy Industry Corporation and 11,000 tons of steel fences.

According to Jimu Journalists, the project board unit components are manufactured in the newly -built board unit in Shuangliu Factory District, Wuyuan Xinzhou District. The production line is mainly composed of plate smart cutting production lines, intelligent welding production lines and bridge steel structure manufacturing information management platforms. Its technical performance has reached the international advanced and domestic leading level, providing strong support for the "smart manufacturing" of the project efficiency.

Intelligent production line

Due to the long and ultra -width of the steel box beam section of the project, at the same time, the sea transportation period across the typhoon season. The navigation pass through the Taiwan Strait with complex water environment and high wind and waves. The safety risk is extremely high. Faced with the large -scale segment transportation problems, the project technicians repeatedly optimized the transportation plan, realized all the safe transportation of 16 榀 steel box beams, and refreshed the record of rolling ships in the largest steel box beam beam beam beam beams in China Essence

According to the staff of the project department, since the project starts, in the face of the new crown epidemic, high -temperature power -limiting difficulties, they stand up to pressure and invest a large number of construction staff to ensure the successful realization of the goal of Helong Festival.
