The main cable stock rack of Lingyuyang Bridge in the Shenzhen -Middle Channel is completed

The tide rose to the sea, flying across the spirit. At the construction site of the core transportation hub of the Guangdong -Hong Kong -Macao Greater Bay Area, the construction site of the Shenzhen -Middle Channel, two main cables about 3 kilometers long jumped from the east and west main tower of Lingyuyang Bridge. On the water surface, the two ends were anchored on a million tons of sea. On September 23, the Guangdong Provincial Transportation Group released the news that the main cable shares of the Lingyangyang Bridge of the Shenzhen -Middle Channel completed the setting up, and the construction of the bridge has made breakthroughs in breakthroughs. Next, it will be transferred to the installation stage of tightening cables, cables and cables.

The Lingyuyang Bridge of the Shenzhen -Middle Channel is the main span of 1666 meters of suspension bridge. The main tower is 270 meters high. It is currently the world's largest span of the steel box beam suspension bridge in the world.

The main cable is the main load -bearing component of the suspension bridge, and it is known as the "spine" of the suspension bridge. There are two main cables on the left and right Lingshengyang Bridge, and the single -rooted cable consists of 199 rosewood stocks. Each cable shares consist of 127 wires and 2060 MPa high -strength durable wires with a diameter 6mm, and single cable stocks can bear the limit of 740 tons.

"We have applied the 2060 MPa main cable steel wires independently developed and manufactured. This is currently used in bridge construction and the highest -level main cable steel wire in China." Chen Huanyong, an engineer of the Chief Work Office of the Shenzhen -Middle Channel Management Center, said, "At the same time, we It also combines the marine environment where Lingyuyang Bridge is located, and has developed a new alloy coating steel wire, which greatly improves the resistance and durability of the main cable. "

The high -intensity and stronger durability main cable steel wire not only enhances the reliability and durability of the bridge, but also is of great significance for improving the level of bridge span, main cable steel wire and cable manufacturing technology. It will continue to consolidate my country's bridge technology International advanced position.

Next, Lingyuyang Bridge will be transferred to the installation stage of tight cables, cables and cables. It is reported that the entire tightening process will be completed within one month.

As the transportation aorta of the Guangdong -Hong Kong -Macao Greater Bay Area, after the opening of the Shenzhen -Middle Channel in 2024, it will change the traffic pattern of the Pearl River East and West Straits, optimize the transportation network, and promote the formation of one -hour living circle between the major cities in the Guangdong -Hong Kong -Macao Greater Bay Area.
