A number of transportation infrastructure has been steadily advanced, and the city of the Greater Bay Area City is in one hour.

The vastness of the ocean, striving for the Greater Bay Area! On June 30, the super engineering of the Guangdong -Hong Kong -Macao Greater Bay Area, the construction of the Shenzhen -Middle Channel, was reported again. The tunnel base groove dredging project was completed. In addition to the Shenzhen -Middle Channel, a number of major traffic infrastructure construction in the Guangdong -Hong Kong -Macao Greater Bay Area is accelerating. The Dongguan Bay Bay Bridge was opened to traffic. Mainland cities with a 2 -hour access and 3 -hour traffic circles from major cities to neighboring provinces.

The deep -sea deep -sea sink tube base slot is completed and completed

On June 30, the Guangdong Provincial Transportation Group released news that the base tank of the deep -sea deep -sea sinking tube of the deep and middle channel was completed. The Shenzhen -Middle Channel is a world -class cross -sea cluster project that integrates "bridges, islands, tunnels, and underwater interoperability". The total length is 24 kilometers, and the submarine tunnel is about 6.8 kilometers long. Among them, the sinking section is about 5 kilometers long. It is currently the widest underwater sink tunnel in the world.

According to Liu Xiaofeng, an engineer of the Island Tunnel Engineering Department of the Shenzhen -Middle Channel Management Center, "The first process of the project's sinking tunnel was installed, which is to deal with the tunnel base groove. Large stasis and difficulty of digging the sand and pit areas are difficult. "

The construction of the base slot of the deep and middle channel sink tunnel has begun since July 2018. Since the construction of the foundation tunnel base slot project of the sinking tunnel, it has been put into the first domestic fine digging of mud, the first deep -sea dredging ship, and a self -navigation rake suction type There are 17 ships such as dredging of mud dredging boats. In more than 1,400 days and nights, the builders overcome multiple factors such as navigation, environmental protection, climate, and geology, and dug a deep -sea base tank about 5 kilometers long and 330 meters wide between the east and west artificial islands of the Shenzhen -Middle Channel. And successfully completed the excavation of the sinking pipe floating channel. Up to now, the smooth installation of 26 sections of 80,000 tons of sinking tube has been guaranteed.

The deepest part of the foundation tunnel base slot is about 40 meters underwater, and the original water depth of the construction area is only 3 to 5 meters. In the case of extremely deep and geological complicated geology, it is like a giant "tofu tofu "Operation. "As a deep -sea project hidden under the water, its construction process accuracy requires reaching centimeter level. It is currently a rare high -precision high -precision excavation and dredging construction in China. Ma Dingqiang, the manager of the Shenzhen Communication Bureau of China Communications Guangzhong Channel, said.

To this end, the construction team has independently developed the first domestic caught -type digging ship "Jinxiong" wheel with a fixed -level excavation function. Its fine excavation control system consists of dozens of sensors and monitors connecting to 7 computers. With this system, the "Jinxiong" wheel can use a huge grabbing of 12 meters high and 90 tons to overcome multiple influences of its own gravity, waves, and sea flow. On the bottom of the 30 meters, the excavation accuracy of the base slot is controlled at 50 Within centimeters.

After 4 years of struggle, all excavation projects were completed in the deep and middle channels, creating a prerequisite for the floating transportation of the last 6 section of the pipe, laying a solid foundation for the establishment of the Shenzhen -Middle Channel in 2024.

In addition to accelerating the construction of the Shenzhen -Middle Channel, the Huangmao Sea Channel, and the Lion Ocean Channel, Guangdong will also promote the preliminary work of the Lotus Mountain Channel to accelerate the formation of cross -river cross -sea channel groups.

"Shenzhen Shekou-Guangzhou 蛇 Heart" combination port is opened

"Guangdong -Hong Kong -Macao Greater Bay Area Port" adds new members. On June 30, the container loaded with fragrance and aluminum rolls in Guangzhou Xunxin Wharf passed the portfolio model to customize the customs clearance, and after the ship was transported to the Shenzhen Port Shekou container terminal through the barge, it was transported abroad through the international flight. Essence It marks the official opening of "Shenzhen Shekou-Guangzhou Xunxin" portfolio port.

Guangzhou Panxin is the sixth portal of Shenzhen Port after the opening of five group ports in the South China Sea North Village, Zhaoqing Sanrong, Yunfu Xingang, Dongguan Shilong, and Guangzhou Xintang. As of now, Shenzhen Port has opened 21 ports in eight cities including Dongguan, Huizhou, Foshan, Zhongshan, Zhuhai, Zhaoqing, Yunfu, and Guangzhou. Shenzhen Port completed the operation of 113,000 benchmarks through the portfolio model, exceeding the annual transportation volume completed through the port mode last year.

In order to enhance the international competitiveness of the port group of the Guangdong -Hong Kong -Macao Greater Bay Area, the Shenzhen Municipal Transportation Bureau, together with Shenzhen Customs, actively coordinated port enterprises in various places, replicated and promoted the "Guangdong -Hong Kong -Macao Greater Bay Area Port" project, encouraged port companies to add more new more new companies In the port point of the portfolio, further expand the coverage of the Greater Bay Area portfolio port, and promote the integrated cooperative development of the port group of the Guangdong -Hong Kong -Macao Greater Bay Area.

At present, the launch of "water transfer" in Shenzhen Port has become an important way to collect and export goods in the port group of the Guangdong -Hong Kong -Macao Greater Bay Area. The opening of the "Guangdong -Hong Kong -Macao Greater Bay Area Port" has significantly improved the efficiency of the import and export of water transfer containers and saving logistics costs.

Dongguan Banhai Bay Bridge is completed and opened to traffic

On the morning of June 30, as the team slowly drove from the sand -horn peninsula to the Chair Bay, the Dongguan Bay Bay Bridge, which was designed by the Chinese Academy of Engineering He Jingtang, was officially opened to traffic. The bridge is to further unblock the "arterial artery" in Dongguan to further unblock the area and participate in the construction of the "Golden Inner Bay".

The Dongguan Bay Bay Bridge is currently the first bridge in the world to use steel shell concrete -the main tower structure of the steel mixed tower. The total length is 973.6 meters, of which the main bridge is 520 meters long, which is two -way 8 lanes. The Dongguan Bay New Area where the Binhai Bay Bridge is located is adjacent to Hong Kong and Macao, which is closely connected to the wide and depths, and is closely connected to the free trade area of ​​Qianhai and Nansha. In addition, the construction of highway reconstruction and expansion projects such as Eastern Shenzhen, Beijing -Hong Kong -Macao (Guangshen), and Guang'ao highways will also be accelerated. In -depth reporters learned that Guangdong was studying and exploring the construction of the Hong Kong -Zhuhai -Macao Bridge to jointly build co -governance sharing. Through transportation, it would fully support the construction of the Greater Bay Area to build a new level.

The construction of the Greater Bay Area Railway Accelerates Promotion

In addition to the construction of the "Golden Waterway" and "Cutting Road Network", the construction of rail transit with considerable capacity has always attracted much attention. Recently, the reporter learned from the press conference held by the Guangdong Provincial Government News Office that Guangdong is accelerating the construction of the Greater Bay Area on the rail. By 2025, the network operations and mileage construction will reach 4,700 kilometers in the Greater Bay Area Railway (including trunk lines and intercity railways), which will fully cover the central cities of the Greater Bay Area, node cities, Guangzhou, Shenzhen and other key urban areas.
