Yueqing Bay Bridge introduction?

Yueqing Bay Bridge (wiring project), the total length of 38.147 kilometers, the entire line of 47 large, large, medium bridges, 4 bridges across the bay, 3 tunnels, a total investment of about 10.387 billion yuan. As a key project of the YongTaizhou-Wenzhou Expressway Duplicate Line, Yueqing Bay Bridge starts from Lupu Town, Yuhuan County, Fenshui Mountain, and ends at Nantang Junction Interchange, Yueqing City, with a total length of 13.1 kilometers, of which 8.9 kilometers are in Yuhuan and 4.2 kilometers are in Yueqing.

Yueqing Bay Bridge and wiring project is Zhejiang Province, "two vertical and two horizontal eighteen even three around the three channels," an important part of the main highway skeleton, but also the Shenhai National Highway, Zhejiang section (Ningbo-Taizhou-Wenzhou Expressway) of the auxiliary lines.

After the completion of the project, will be built with the proposed Sanmen Bay Bridge, Taizhou Bay Bridge and wiring project to form a new coastal highway in Zhejiang Province, to improve the regional highway network, improve the port capacity, strengthen the Yangtze River Delta, Zhejiang coastal and Fujian West Coast Economic Zone traffic links between the economic and social development of the region along the route has an important role in promoting

Started the construction

December 12, 2011, the Yuhuan Economic Development Zone, the second phase of the whirlpool gate dam Eagle Island a joyful, YongTaizhou-Wenzhou Expressway duplicate Yueqing Bay Bridge officially started construction, which marks the construction of Taizhou "Twelfth Five-Year Plan" during the construction of the longest mileage, the largest investment in highway projects - -Ningbo-Taizhou-Wenzhou Expressway re-route project construction of Taizhou section kicked off.

Ningbo-Taizhou-Wenzhou Expressway re-route construction, not only help to ease the traffic pressure of the Yongtaiwen Expressway, but also help to realize the Ningbo-Zhoushan Port, Taizhou Port, Wenzhou Port three ports and the national high-speed network seamless connection, and to further build the China Coastal Expressway. The construction of Yueqing Bay Bridge will also allow Yuhuan to say goodbye to the history of not being able to access the highway, fundamentally solving the traffic bottleneck constraints in Yuhuan, and fulfilling the Yuhuan people's dream of a cross-sea bridge.

September 26, 2014, Yueqing Bay Cross-sea Bridge hit the first pile of the main bridge

The deep water and wide harbor of Yueqing Bay is welcoming one of the most significant human activities in thousands of years. In its deep sea, the depth of the soil, 538 marine cement piles will support the cross-sea bridge No. 1 bridge, it is the name of Yueqing Bay, a hundred years for its mission. Generations of people dream of the eastern coastal corridor also opened the two veins, into the galloping north and south, combined with the fast lane.

Yesterday, Yuhuan County, the water village Yueqing Bay Bridge No. 1 bridge on the trestle, with the China Communications Construction Group, the first highway engineering bureau (hereinafter referred to as "CCCC a public bureau") construction unit of a command, Yueqing Bay Bridge, the first pile of the main bridge to start hitting. The drill bit falls into the 17-meter-deep seawater, kisses the ensuing sea mud, accompanied by splashing mud and water, and rotates smoothly into the deep sea. Soon, a 112-meter-long first pile of the main pier will stand in the sea water, and it means that this cross-sea bridge has entered the substantial construction stage of the main project.

As an important part of the Yueqing Bay Bridge and wiring project - Yueqing Bay Bridge No. 1 project, is now officially launched Yueqing Bay Cross-Sea Bridge of the opening work, which started in the town of Lupu water-sharing mountain pier, stopping in the Haishan Township, Maotao Theatre Island, a total length of 4.3 kilometers, 33 meters wide, in accordance with the standard of bidirectional six-lane highway Construction, design speed 100 kilometers per hour, total investment of 1.236 billion yuan, the planned construction period of three years, by the CCCC First Public Bureau is responsible for the construction.

The future of the bridge: "traffic flow, economic flow, the flow of ideas," three streams of smooth

Since the reform and opening up, the rapid economic and social development of the Yuhuan economy and social development, the overall strength of the country's small and medium-sized cities among the top 100. But in stark contrast to this, Yuhuan as an island county, still belongs to the end of the land transportation, so far no national highway, no high-speed, no railroad, only by 76 provincial highway and its duplicate line and Yueqing Bay Roll-on Roll-off ferry to maintain access.

"Yuhuan external transportation is seriously lagging behind the economic and social development, YongTaiWen highway re-route project is a fundamental solution to the Yuhuan traffic bottleneck constraints of the problem." Zhang Gabo, secretary of the Yuhuan County Party Committee, stated the key significance of the Yueqing Bay Bridge and the high-speed channel for Yuhuan.

Dong Guibo, deputy mayor of Taizhou City, has a deeper understanding, evaluation and expectations of the Yueqing Bay Bridge construction: "The entire Taizhou coastal high-speed planning for 10 years, the real operation of 8 years, and now 10 years of hard work into the excitement and happiness. Yueqing Bay Bridge is Taizhou's No. 1 project, but also a masterpiece in Taizhou's transportation history, I hope to build it into a star bridge and first-class project, with elite soldiers and strong generals, to create a benchmark and model, and take the project as an opportunity to drive and lead other transportation projects in Taizhou."

Behind the eager eyes of the people of Taizhou is a compilation of reports on various topics that keep accumulating in the Yuhuan County Coastal Highway Project Construction Command. "The tough work is all in the early stage, in order to prepare for the construction of this cross-sea bridge, the engineering feasibility study reports on 27 topics from geology, hydrology, climate, maritime to water conservancy, flood control, etc., are piled up to be a few people high."

In fact, the social development of the rapid changes, far more than a set of formulas to predict the outcome of the rapid. Nguyen Dung gave an example to the reporter: "In 1998, the Roll-on Roll-off Ferry Co. put in two boats to carry more than 400 cars a day. But with the increasing traffic, as of August this year, the ferries have increased to five, carrying more than 2,000 cars a day, with occasional congestion and queues."

Economic development, especially the development of e-commerce in recent years has led to increasingly active logistics, with an unprecedented increase in motor vehicle ownership and a steep rise in traffic.

In June 2011, as a provincial key project, the Yuhuan Chenyu Tunnel and wiring project was officially opened to traffic. The completion and opening of the tunnel was aimed at easing the bottleneck problem of increasing local traffic in Yuhuan and playing a key role in the development of the state class one port of Damaiyu harbor and direct flights to Taiwan. "At first, according to technicians' on-site statistics and formula calculations, the number of vehicles traveling to and from the tunnel was just a few hundred times a day, but at present, the actual traffic flow of the Chenyu Tunnel has reached a daily average of 50,000 vehicles."

"To get rich, build roads first. This old saying is still an unbreakable and tried-and-true truth in Yuhuan's economic development." Ruan Yong said, such as can be completed as soon as possible Yueqing Bay Bridge across the sea, will enable Yuhuan deeper into the Yangtze River Delta economic circle, and both Wen and Taiwan economic integration, linkage development of the benefits; also prompted the Damaiyu Port to expand the scope of operations, expand the economic hinterland, bringing objective port economic benefits.

Constructor's promise: to build a modern bridge that will stand for a hundred years as a specimen

Li Rang is the deputy chief engineer of CCCC's Yueqing Bay Bridge No. 1 project. "Two years ago, the construction of the offshore construction platform trestle for Bridge No. 1 began, and now it has been fully completed, and the main bridge project officially starts from today."

Yueqing Bay Bridge and the connecting line project construction commanding general director, Yuhuan County Standing Committee, deputy mayor Ye Nan said, CCCC No. 1 bridge project construction team, is a first-class team in China, the use of continuous rigid structure and segmental prefabrication technology is also the most advanced technology in the country. The goal of this project is to create a "Ministry of Excellence".

The bridge's symphonic music, which belongs to Li and his colleagues for the next three years, begins with the "thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump, thump" of the first piles hitting the rock layer.

"Because the approach bridge and the main bridge pile foundation is located in a different location, the pile foundation is divided into land piles and piles in the water. 1 bridge total **** there are 64 piers, each pier, by as few as 8, as many as 18 piles support." Li rang said.

The seawater on both sides of the main channel is the deepest and the piles are the longest, at 106 meters, equivalent to the height of a 35-story building. "The process of driving the pile foundation into the deep sea is the most worrying, in addition to the on-site workers, all managers and engineering commanders must work 24-hour shifts, uninterrupted duty, and any abnormalities in the efficiency of the drilling work means that the operation in the sea has encountered an obstacle, which must be handled with vigilance at all times."

The Yueqing Bay Bridge No. 1 is a very long project with a large volume and high engineering difficulty. Especially after the adoption of "section prefabrication" technology, the engineering difficulty is further increased. However, the advantages of the technology are also very obvious, different from the traditional "bridge site casting" technology, section beam prefabrication, is divided into different sections of the whole beam, in the beam factory pre-production, and then lifted to the bridge, for splicing. This not only reduces environmental pollution, but also ensures that the construction process minimizes the impact on navigation.

"But the construction difficulty is also here, on-site splicing, light, temperature, wind, etc. are factors affecting the accuracy of splicing, in order to ensure the accuracy of on-site construction, we specialize in joint colleges and universities for laboratory 1 to 10 simulation experiments." Li rang told reporters.

"All the technical and management requirements of the cross-sea bridge are aimed at the standard of a hundred-year project. It will record the century-long development of the coastal economy and personnel changes, as well as the tenacity and pursuit of our group of builders." Hu Fengming, executive deputy manager of the project manager department of Yueqing Bay Bridge No. 1 of CCCC Yigong Bureau, said.
