Brief introduction of Guangzhou Haiyin Bridge?

Guangzhou Haiyin Bridge is named after Hai Yin Stone in Shisan, Yangcheng, where the northern end of the bridge is located. The bridge is located in Dashatou, Guangzhou City, Guangdong Province, China, connecting Yuexiu District and Haizhu District, crossing the Pearl River, with a total length of about 1 130.75 meters, connecting Donghu Road in the north and Dongxiao Road in the south. An approach bridge has been built to connect Jiang Yan Road and binjiang road. The bridge is a cable-stayed bridge with twin towers and single cable plane, with a total length of 1.25m and a tower height of 57.4m It is star-shaped by 1.86 steel cables, and the top of the tower looks like two "corners", symbolizing Yangcheng. On the Hai Yin Bridge, there is the image of a brig that is sailing at sunrise. It is the fourth unique highway bridge on the Pearl River, just like two huge harps playing melodious music with beautiful running water in summer nights.

bridge design

Haiyin Bridge is located in the center of Guangzhou, Guangdong Province, across the Pearl River, 2.5km away from Haizhu Bridge, with a total length of114m. The facade is an inverted "person". Fan-shaped cables are arranged, and the cable spacing is 5m. There are 6 lanes on the bridge deck with a width of 35m. The main girder adopts inverted trapezoidal box section. The cantilever of the roof is 7.5 meters long. This bridge has a good wind-resistant section. The temperature stress problem adopts a unique design structure and treatment method to adapt to the situation of large temperature difference at the bridge site. The main girder construction adopts a unique method of pouring the middle box first and then pouring the side boxes on both sides, and adopts hanging basket construction instead of rigid skeleton. 1988 was completed and opened to traffic. Designed by Shanghai Municipal Engineering Design Institute and constructed by Guangdong Basic Engineering Company.

figure

Haiyin Bridge is a cable-stayed bridge with twin towers and single cable plane. The main bridge is 340m long, with a total length of114m and a tower height of 57.4m.. Fastened by 186 steel cable, the top of the tower looks like two "corners", which means Yangcheng. It is 2 .5 kilometers away from Haizhu Bridge. The main bridge is a prestressed concrete cable-stayed bridge with twin towers and single cable plane, with a span of 175m, three holes under the bridge, a middle hole span of175m and a side hole span of 85.5m.. The main bridge adopts the world's advanced pier-tower-beam consolidation structure system, which is a single-sided twin-tower concrete cable-stayed bridge. The aperture arrangement is 35+85 .5+ 175+85.5+35 (m).

Double-row flexible piers are used for pier shafts to meet large temperature deformation and avoid setting large-tonnage sliding bearings. The tower is about 60 meters high, and the facade is inverted Y-shaped. Fan-shaped cables are arranged, and the cable spacing is 5m. The bridge deck has six lanes and is 35 meters wide. The main bridge is an inverted trapezoidal three-box type. The cantilever of the roof is 7. 5 meters long. The top is shaped like a sheep. 186 steel cable is cable-stayed on the twin towers, forming a huge fan-shaped structure.

The development of history

From June 65438 to June 0985, the fourth Pearl River Bridge, designed by Shanghai Municipal Engineering Design Institute and constructed by Guangdong Basic Engineering Company, started construction, which was the largest cable-stayed bridge in Asia at that time.

The bridge has been completed and opened to traffic. It was named "Hai Yin Bridge" because there were three Hai Yin in Yangcheng at the northern end of the bridge.

1992, Haiyin Bridge won the Luban Award, the highest prize of China's architectural engineering.
