Why do you connect to the sea and grow high in Zhejiang high speed?

Zhejiang News Client reporter Zhang Fan

Yesterday, the largest maritime interoperability project in Asia, the Hangzhou -Ninguka Reunion Line Expressway and the intersection of the high -speed intersection of the high -speed boat high -speed, completed the construction of all 1745 concrete pile holes, and firmly rooted in the shallow beach outside the mouth of the Yongjiang River.

After three years of construction, today, Zhejiang's first high -speed -Shanghai -Hangzhou -Ningbo high -speed Hangzhou city section has also successfully lifted up. In the future, it will be transformed into Hangzhou's new airport elevated and airport avenue.

Interchange into the sea and grow high. Why does Zhejiang high -speed deformation meter?

In the construction of the Hangzhou -Ningbo Reproduction Line Ningbo Phase I Phase 1

Two reasons

The shortage of land resources and traffic path resources is obviously the main reason.

There are more people and less land, and the cultivated land needs to be protected. Land indicators have always been one of the bottlenecks in Zhejiang's transportation construction.

The shortage of traffic path resources between the two places is an increasingly prominent problem in the developed areas of Zhejiang coastal in recent years. Because the industrial areas, residential areas and the original roads along the way are too dense, it is difficult to choose a path that occupies less land and less demolition, especially in the high -speed construction of the two places.

The demand for economic development for highways, urban expressway, high -speed rail, and urban orbit is still growing. Where is the space for construction?

Methods are always more difficult than difficulties.

The Shanghai -Hangzhou -Ningbo Expressway is the first highway built by Zhejiang Province. Since the opening of traffic at the end of 1998, it has provided important support for Zhejiang's economic and social development.

As the process of urbanization continues to accelerate, as the only two -way four -lane high -speed speed in Hangzhou around the city, it can no longer meet the comprehensive needs of urban space expansion.

In order to give full play to the role of its comprehensive channel resources, in December 2018, the Hangzhou Municipal Party Committee and Municipal Government decided to implement the overall and reconstruction of Shanghai -Hangzhou -Hangzhou high speed.

After the transformation of the height, the project will be greatly upgraded to expand the capacity of crossing the river crossing through the riverside passage of Hangzhou City. The original four -lane ordinary highway has become an 8 -lane high -speed expressway and ground city road. The two -line express rail crosses the Qiantang River, and the first time the Hangzhou Metro has provided room for space.

One path resource to achieve triple sharing.

Pengbu interoperability in the reconstruction project of the Shanghai -Hangzhou -Ningbo high -speed Hangzhou city section

The coastal interoperability in the roots of the sea also has the same magic.

Binhai Interchange is the hub of interconnected interoperability in the construction of the Hangzhou -Ninguka Reunion Expressway (Hangzhou -Shaoxing highway) and the opening of the Kentang Bridge (one of the main bridges of Zhoushan cross -sea bridge) in the opening of the Yongzhou Expressway (Zhoushan Cross -Sea Bridge). At the beginning of the design, where to set up interoperability is a problem.

The local is the chemical area of ​​Ningbo. The famous Zhenhai refining is located here. It is the most advanced and largest refinery in Sinopec and a group of chemical companies. The Hangzhou -Ninguki compound line is connected to the highway on the land through the chemical factory area, and the demolition volume is large.

The coastal shallow beach and beach coating outside the chemical area attracted the attention of the designer. From Lu Xianghai, it was suddenly cheerful.

After obtaining the consent of the management department of the waters, on the gray talcum shallow beach of about one kilometer outside the coast of Zhenhai, the high -speed high -speed high -speed of the six lanes, Hangzhou -N, Nagato compound lines, and more than 10 kilometers along the coast of the coast, and the Jinsang Bridge Meet each other to form the largest maritime interoperability in Asia -coastal interoperability.

Relevant builders revealed that this change not only saves land, reduces hidden dangers of operation, but also reduces the cost of relocation of the project, saving construction funds. The 55 -kilometer Hangzhou -Ninguki Reunion Line Ningbo's first -phase relocation fee was more than 3 billion yuan, and the Hangzhou -Ninguki compound line of 50 kilometers of Hangzhou -Shao section, although it also adopted the entire line, try to use the original road path and other methods. 78 billion yuan.

Of course, the three -dimensional layout is necessary to use the path, and make full use of the marine resources of the ocean provinces in Zhejiang, and the cost is not small.

The reconstruction project of the Hangzhou City section of the Shanghai -Hangzhou -Ningbo Expressway has a total investment of about 13.669 billion yuan. The first -phase investment budget for the Hangzhou -Ningbo Reunion Line is 17.991 billion yuan. For the construction steel trestle built by the construction of sea interoperability, the cost per meter is 16,000 yuan. Every step here is worth 10,000 yuan.

The idea changes the world wide and the earth is wide

If you pay, there will be returns.

Modern transportation in China, the number one in Asia, and the world first, was born.

The new Pengbu Bridge in the Hangzhou City section of Shanghai -Hangzhou -Ningbo Expressway is the first multi -inter -long -term long -use suspension chain -shaped steel truss bridge.

The newly -built Qiantang River Bridge

The coastal interoperability is the largest interoperability in Asia. It consists of a main line bridge and 8 ramp bridges. The total length of the ramp is 6387 meters, accounting for 613 acres of the sea area. In order to transport these guys to the interoperability of the sea, for the first time in my country, the JQ1800 "Yuehai" bridge machine currently in the world's largest highway bridge machine is currently successfully resolved in the beams of beams to successfully solve these heavy weights. The pores of the rectification of 1800 tons are settled.

In the next step, the project will also be put into the use of a MJ700 width beam bridge machine currently the largest horizontal span in China. It is mainly used for the width beams on both sides of the three interconnected main bridges of Xupu, Binhai and Weihai.

It can be said that the change of thinking has not only eased the problem of construction land, found more path resources, but also refreshed the traffic construction record, and provided new opportunities for the transportation industry and equipment development.

Of course, for Zhejiang, more significance is that more traffic infrastructure can be accelerated, and the communication and circulation between regions are more convenient because of the dense transportation network. For example, the Hangzhou -Hangzhou -Ningbo Expressway Hangzhou City section can quickly connect the Shanghai -Kunming Expressway, Hangzhou Bay Ring Road Expressway, and other arteries in Hangzhou City. In order to promote the integration of the Yangtze River Delta and sing the "Hangzhou -Ning Dynasty Twin Cities" and other major national strategies to play a leading role in transportation.

The construction of the coastal interoperability in the Hangzhou -Ningbo Reunion Line and the coastal interoperability in the sea is an important iconic project for singing the "Shuangcheng" of Hangzhou -Ningbo and the Ningbo Northbound Freight Channel.

After the completion of the first phase of the Ningbo project of the Hangzhou -Ningbo Reunion Line, it will be greatly convenient for citizens along the Western Yuyao, northern Cixi, east and other places to improve the national highway network and Ningbo Zhoushan Port Marveling Network, which will be unblocked in Ningbo. The external channel of Zhoushan is of great significance to promote the implementation of national strategies such as the Zhejiang Ocean Economic Development Demonstration Zone.

Among the two or three kilometers south of the coastal interoperability, another small sea interoperability in Weihai is also under construction.

In the future, the third phase of Ningbo of the Hangzhou -Ning Dynasty will depart from here. Continue to travel through the gray ocean, cross the Yellow River, and reach the Beilun Chai Bridge on the mountain peninsula, and connect with the six -horizontal bridge in the construction, becoming the north bank of Hangzhou Bay and the Zhoushan Islands Multi -Island interconnection fast channels.
