Experience China Super Engineering at 270 meters high altitude

Reporter Liang Xili Liu Wenbo

On the 26th, Global Times-Global Network reporters boarded the Cat Road Cat Road of Lingyangyang Bridge of the Congzhong Channel of the Guangdong-Hong Kong-Macao Greater Bay Area, participating in the global live broadcast of the "Supreme Cat Road in the World" and "Super Project China Construction" state-owned enterprises. Open day event. In the thrilling experience of 100 meters at sea at sea, the reporter and his party faced the world -class Chinese super engineering and witnessed the "hard core" intellectual construction technology of the Chinese bridge. They felt the powerful strength behind the super engineering miracle. Hua Chunying, a assistant minister of China Foreign Affairs, recommended this event to netizens around the world on Twitter that day. The event was guided by the State -owned Assets Supervision and Administration Commission of the State Council, and the Global Network and China Communications Construction Group Co., Ltd. (referred to as "CCCC Group") linkage live broadcast. With the support of 5G technologies of China Unicom's "highest 5G base station in the world", 300 million netizens around the world "onlookers" this event.

The white clouds on the head are flying, and the surface of the foot is rolling

The Shenzhen -Middle -Middle Channel of the Guangdong -Hong Kong -Macao Greater Bay Area, also known as the "Shenzhen and Middle Bridge", is a world -class cross -sea channel cluster project that integrates "bridges, islands, tunnels, and underwater interoperability". In the construction of Zhongshan City, the Bridge of Zhongshan Starts from Hezhou, Baoan District, Shenzhen, and the Hengmen Hub in the west to Zhongshan City. It adopts the East Tunnel West Bridge Plan.

The Lingyuyang Bridge, undertaken by the Second Airlines Bureau of CCCC Group, is a key control project of the Shenzhen -Middle Channel. The "Cat Road" is a temporary construction lane set under the construction of the suspension bridge under the main cable and parallel to the main cable -shaped. There are two main cables on the Lingshengyang Bridge, 3,000 meters of cat roads, about 1700 meters between the two main towers, and the highest point is 270 meters from the river surface, which is equivalent to 90 floors. The lowest point is close to 30 floors. high.

Global Times-Global Network reporters looked at the bridge at the Lingyu Ocean face, and the 270-meter-high Lingyuyang Bridge's main tower went straight into the clouds. The anchor is rooted in the sea like a giant "scale", and the cat road seems to be two suspended thin lines. When the reporter and his party boarded the highest point of the cat road, the white clouds were flying above the head, and the surface of the feet rolled. Although some feet were soft, they still felt like "through the clouds and crossing the sea". Standing on the Lingyuyang Bridge Cat Road to the north and south, the Humen Bridge and the Hong Kong -Zhuhai -Macao Bridge were visible to the sea.

"Work" at the high altitude, experience the setting tie of the front -line construction operation; ascend to the surface of the Lingsheng Ocean, the ancient poetry competition ... Under such a height, the participants successfully conducted the global broadcast "The highest cat road in the world" challenge event. Essence The reporter learned from the "Bridge '" popular science question and answer session that despite the temporary facilities, the Lingyuyang Bridge Cat Road is still designed in accordance with the standard of Anti -14 typhoons. The cat trail consists of two -layer galvanized steel wire mesh, and anti -slip wooden strips are laid on the wire of the wire. A live contestant said with emotion in the face of the live broadcast.

Two "artifacts"

It is reported that since the construction of the Lingyuyang Bridge, the three "worlds are the most" that has created the construction of the whole sea -the world's largest span -in -sea seabed steel box beam suspension bridge, the world's largest anchor, and the world's highest sea bridge. The construction of the Lingyuyang Bridge is recognized as the "five major difficulties": the large -scale anchor infrastructure in the sea is difficult, the construction of the concrete ultra -high Soka is difficult, the upper structure of the large cross -suspension bridge is difficult, the construction of the lower part of the non -passing bridge is difficult, and the full structure is difficult, and the full is full. The construction organization at sea is difficult.

The Pearl River Estuary where the Lingshengyang Bridge is open, and it is also a strong typhoon frequent area. Large span continuous high -altitude operations, the builder's psychology and body are facing great challenges. "There is a big difference between sea construction and land. There are winds during the day and night. When windpower is difficult to predict in advance, in order to ensure the construction progress, we will be on duty and seize the window period with small wind power." Deputy Manager Liao Linchong said.

It has the best in supporting China's super engineering. In addition to the persistence of the front -line builders, it is inseparable from the intelligent construction technology and equipment under the leadership of scientific and technological innovation. The construction of the Lingyuyang Bridge has a "intelligent" gene. To build such a high bridge at the sea, the builders of the China Communications Second Aviation Bureau relied on two "artifacts "-" patching wood "and" air mobile factories ". The steel bars are quickly assembled in the factory, and then transported to the scene as a whole. The tower crane with a lifting capacity of up to 80 tons is lifted, connected, and installed, just like the patching of the patch, each section is assembled together. The "Air Mobile Factory" is an intelligent tower -built machine independently developed by the CCCC Second Aviation Bureau. In the smart tower building machine, the builder completes the construction operation according to the height automatic lifting.

From the perspective of Zeng Wei, deputy chief engineer of the Second Airlines Bureau and the Deputy Chief Engineer of the Shenzhen -Central Channel Project, the reason why the Lingyiyang Bridge can achieve so many innovative results is inseparable from the full planning and full planning and full planning of bridge technology experts Preparation, this is also the most important reason for the construction of the Lingyuyang Bridge to build the world. "China moves from a large country from building a bridge to a strong country to build a bridge and competing with foreign counterparts. It is the core technology that is the core technology." Jiang Mingpeng, deputy chief engineer of the project, has been in the industry for many years. This is the fifth suspension bridge he has participated in construction.

Flowing, logistics, and information flow are further unblocked

At present, the Lingyuyang Bridge has entered the stage of the main cable, and the construction of various projects in the Shenzhen -Middle Channel is also steadily promoting. It is expected to be opened to traffic in the deep channel in 2024, and the fast -to -Shenzhen commute time from Zhongshan has been reduced from 2 hours in the past to 30 minutes. For citizens in Zhanjiang, Maoming, and Yangjiang, Guangdong Province, the current status of congestion traffic in Shenzhen must be completely changed. The significance of the deep and middle channels is far more than that of transportation construction. For a long time, the cities in the Guangdong -Hong Kong -Macao Greater Bay Area are divided into two by the Pearl River Estuary, distributed on both sides of the Pearl River Estuary. "From the perspective of the total economic development, the quality of development, and the speed of development, there is a very large regional difference between the East and West Straits of the Pearl River. The vice president of the hospital, Qu Jian, compared with the Nanshan District of the East Bank of Zhujiang and the Cuiheng New District of the Zhongshan New District of the Pearl River as an example: less than 200 square kilometers in Nanshan District, creating more than 700 billion yuan GDP, Cuiheng New District more than 200 square kilometers of GDP Less than 20 billion, "This is a very shocking thing."

The urban groups on both sides of the Pearl River Ests, which were once partitioned by Lingyuyang, were connected by the Shenzhen -Middle Channel, the Hong Kong -Zhuhai -Macao Bridge, the Nansha Bridge, and the Humen Bridge. Wang Xianqing, president of the Guangdong Provincial Commercial Economic Society, told reporters that the industrial layout on both sides of the Pearl River is obvious. The east coast is mainly concentrated in the electronic information industry and modern service industry; the west coast is dominated by traditional manufacturing industries such as home appliances and machinery. In the future, benefiting from the construction of the deep and middle channels, the flow of people, logistics, and information flow will be further unblocked. ▲
