The Pearl River Estuary stands more than 200 meters high "harp"!Shenzhong Channel Zhongshan Bridge Helong

On June 28, the reporter learned from the Guangdong Provincial Transportation Group that as the last steel box beam completed the welding operation, the Zhongshan Bridge of the Shenzhen Channel was officially united. The bridge across the East Channel of the Pearl River Estuary, such as the huge "harp" standing in the river and sea, not only laid a solid foundation for the completion of the Shenzhen -Middle Channel in 2024, but also played the "Golden Gold of the Guangdong -Hong Kong -Macao Greater Bay Area and the Huanzhu River Estuary" Golden Inner Bay "Development strong sound.

The Shenzhen -Middle Channel is the core hub project of the Guangdong -Hong Kong -Macao Greater Bay Area, with a total length of 24 kilometers, of which the bridge project is about 17.2 kilometers. Zhongshan Bridge is one of the key control projects of the project. It is the two -tower cable -stayed bridge that spans 580 meters. The main tower is 213.5 meters high. It is connected to the main tower and bridge deck from 120 cable cables, such as the "harp" jumping on the sea.

The steel box beams of Helong section are 10 meters long and 46 meters wide, and weigh 233 tons. The construction staff operates 4 bridge cranes to hang the steel box beam to the design elevation, and then after a few hours of line -shaped adjustment, welding and other processes, and left and right left and right The welding of beam sections on both sides has been set up, and the last "building blocks" are accurately supplemented. On June 28, the last welded seam on the steel box beam panel completed the welding, marking the successful dragon of the Zhongshan Bridge, and then the construction stage of the road and the auxiliary facilities will be transferred.

Since the start of the Western Artificial Island in December 2016, by June 2022, the Zhongshan Bridge Helong has started construction for five years and six months. Pioneering and innovating, safe, efficient, and high -quality promoting project construction has achieved a lot of attention. The Zhongshan Bridge Heilong officially sounded the sprint horn built in the last two years of the Shenzhen -Middle Channel.

Since the first steel box beam of Zhongshan Bridge was lifted smoothly on November 24, 2021, the construction team lasted for 7 months and completed the high -precision high -precision of 69 steel box beams.

The Zhongshan Bridge is located in the entrance of the Pearl River. It is hot, humid, high salt and fog, which is easily affected by typhoons. The complex geological and climatic conditions, and the structure of large spans have put forward higher requirements for the bridge steel box beams.

"At present, intelligent manufacturing is still in its infancy in the field of domestic steel box beam manufacturing. The Shenzhen -Middle Channel has developed and created China's first large steel structure intelligent manufacturing production line, which greatly improves the stability and production efficiency of the box beams. It also innovated the integration of group welding and full melting welding technology, improved the anti -fatigue performance of orthogonal heterosexual steel bridge panels, and greatly improved the durability of the steel bridge panel. " Essence

Han Qingguang, the project manager of the Zhongtie Mountain Bridge of Zhongshan Bridge Steel Box Steel Lighbor, said that the construction team integrates the organic production lines and digital equipment such as welding, assembly, and coating robots in the construction team. The characteristics of large structural size, diversified welding position, and high accuracy requirements have improved by more than 30%, making Chinese bridge construction technology and quality reaching the world's advanced level.
