Information of Jiangyin Yangtze River Bridge

The Jiangyin Yangtze River Highway Bridge, the first bridge in China, is located between Xishan, Jiangyin City, Jiangsu Province and Shiwei Village, Jingjiang City. The bridge adopts a one-span, long-span steel suspension bridge type across the river. The main span is 1,385 meters. , currently ranked "No. 1 in China and No. 4 in the world", was completed and opened to traffic on October 1, 1999.

With the completion of the Elbizui Park Observation Tower and the opening of the "Yangtze River Star" luxury cruise ship. , Jiangyin Yangtze River Bridge Scenic Tourist Area has formed a new pattern of three-dimensional tourism in the air, on the river, and on the shore. In the Elbizui Park, there are Riverside Xiaobu, Jiangwei Haitou, Ming and Qing Cannons, Xianren Cave, Hanjiang Fishing, and Cloud Watching. Twenty scenes such as Tingchao, whose architectural complexes of buildings, pavilions, pavilions, and corridors are integrated with human and natural landscapes such as mountains, water, bridges, cannons, and caves, forest wooden houses, waterside fishing nets, fishing and hunting barbecues, etc., are all in sight. It allows tourists to return to nature, feel wild and experience the real vacation experience.

The sightseeing tower on the top of the mountain echoes the Wangjiang Tower in Dongshan and the Yangtze River Bridge. The river and the sky are the same color, and the river and bridge are one wonder. At the foot is the majestic Yangtze River, and the tower of China's First Bridge stands majestically a hundred meters away. Two small round table-top-thick suspension cables are pulled up to lift the bridge over the sky moat. On the other side, the sky appears like a "cloud dragon" floating on the vast river. Looking at the two sides of the river, there are vast plains, harbor hangers, soaring gulls, sea ships passing by, and the Yuanwang Surveying Bridge looking like a white swan resting quietly. The prosperity of the modern riverside port city is even more visible.

Transportation: Jiangyin Bus No. 6 and 8 can be reached.

Tickets: 15 yuan, 5 yuan for the Battle of Crossing the River Memorial Hall. The sightseeing tower is 15 yuan, the Yangtze River cruise is 10 yuan, and the luxury high-speed boat is 30 yuan.

Opening hours: 7:00--17:00

There is a saying in the international bridge industry: To judge the level of a country's bridges, you have to look at the level of its suspension bridges, and the sign of its advanced technology is the span. The construction of such a large bridge with a main span of more than 1,000 meters on the vast Yangtze River has broken the "Chinese" standard. The myth that "long-span bridges cannot be built".

The well-known Jiangyin Yangtze River Bridge is the "first in China and fourth in the world" extra-large-span steel suspension bridge.

No. 1 in the world: Japan The Akashi Kaikyo Bridge was built in 1998, with a main span of 1,990 meters;

Second: Denmark’s Humber Bridge, under construction, with a main span of 1,624 meters;

Third: Britain's Humber Bridge, built in 1981, with a main span of 1,410 meters;

Fourth: Jiangyin Yangtze River Highway Bridge, built in 1999, with a main span of 1,385 meters;

Fifth: Hong Kong Tsing Ma Bridge, completed in 1997, with a main span of 1,377 meters.

Difficulty Even though there are successful examples of suspension bridges in foreign countries, due to the problems of Jiangyin and Jingjiang. Due to the unique local geology, hydrology, and climatic conditions, foreign experience cannot be completely copied. There are still many technical difficulties in the process of building the bridge, which are briefly described as follows:

The north anchor caisson - the bridge. The two anchor spindles in the north and south must "pull" the main cable of the bridge together. The tension of the main cable is 64,000 tons. The north anchor spindle is located on the alluvial plain. The plane dimensions of the underground caisson are 69 meters long and 51 meters wide, with an area of ????enough. 10 basketball courts are large, and the subsidence has to go through 4 layers of different soil textures. If you are not careful, it may cause serious problems such as skewing and torsion. The sinking process lasts for 20 months.

Main cable erection - The main cable is the main load-bearing component of the Jiangyin Bridge. It can "lift" the steel bridge deck with a total weight of 18,000 tons and the asphalt road surface of 5,000 tons, as well as the driving live load. The Jiangyin Bridge has two main cables, each weighing 8,400 tons and consisting of 169 cable strands, each weighing 50 tons. The main cable erection adopts the prefabricated parallel strand method (PPWS). Each cable strand weighing 50 tons and 200 meters long is erected in the air. From traction, tensioning, forming to cable adjustment, every link has There are many unforeseen technical difficulties, and working at high altitudes at night is greatly affected by weather. Its erection difficulty is unique in China.

Bridge Deck Laying - Lay asphalt concrete with a thickness of 5 cm on the steel box girder bridge deck. Due to the strong thermal conductivity of the steel box girder, the temperature is very high in summer and very low in winter. The characteristics of the asphalt are difficult Take care of both sides. The temperature conditions in Jiangyin are worse than those in Western countries, ranging from -15°C to 70°C. With no precedent to follow, after more than a year of research and testing, a solution that can meet the specific requirements of the Jiangyin Bridge was finally found. Solved the world's problems.
