Haiyin Bridge

Haiyin bridge is a river crossing channel connecting Yuexiu District and Haizhu District in Guangzhou City, Guangdong Province, China. It is located on the north main stream of the Pearl River and is one of the main roads in Guangzhou city.

Haiyin bridge was built in July 1985;

It was completed and opened to traffic on December 27, 1988;

It stopped charging in January 2001.

Haiyin bridge is connected with Donghu road in Yuexiu District in the north, the Pearl River Waterway in the upper and Dongxiao road in Haizhu District in the south. The total length of the line is 1130.75 meters, and the main bridge is 416 meters long. The bridge deck is a two-way six lane urban trunk road with a design speed of 60 km / h.

Construction process

In July 1985, construction of Haiyin bridge, formerly known as the fourth Pearl River Bridge, began.

In December 1988, Haiyin bridge was completed and put into operation.

In January 2001, Haiyin bridge stopped toll collection and demolished toll collection facilities.

From November 23, 2016 to mid January 2017, Haiyin bridge was under repair.

On August 23, 2017, the dynamic and static load test of Haiyin bridge was carried out, and the two-way closure construction was carried out; on August 25, 2017, the closure construction of Haiyin bridge was completed.

Bridge location

Haiyin bridge is located in ershatou, Yuexiu District, Guangzhou City, Guangdong Province, China. It is 0.8km away from Jiangwan bridge in the West and 3.2km away from Guangzhou Bridge in the East. The North approach bridge connects Donghu Road, Yuexiu District, and crosses and interchanges Yanjiang Road. The south approach bridge connects Dongxiao Road, Haizhu District, and crosses and interchanges Binjiang Road.

Architectural design

building structure

Overall layout

Haiyin bridge is composed of main bridge on water, north-south approach bridge on land and interchange ramp. The whole section of the bridge is roughly arranged in the direction of due south and due north. The bridge tower is located in the center of the cross section of the bridge deck, which is the median of left and right traffic lanes. Bicycle lanes and sidewalks are set on both sides of the bridge deck.

 

Design concept

Haiyin bridge is the first cable-stayed bridge in Guangzhou. The name of Haiyin comes from Haiyin stone in Sanshi, Yangcheng, at the north end of the bridge.

 

The top of the tower of Haiyin bridge is like two "sheep horns", implying the city of Yangcheng. Under the construction of lighting, Haiyin bridge is like a two masted ship sailing in the rising sun. At the same time, it is like two huge harps playing the light and shadow movement of the Pearl River with the colorful water pattern on the river, With the changing color of the light flow, the river is rendered colorful and gorgeous. The dynamic and static art of the bridge has got a new interpretation here.

 

Design features

Haiyin bridge is the first prestressed concrete box girder cable-stayed bridge with double pylons and single cable plane built in China;

 

The main bridge is a three span cable-stayed bridge with braided cable plane. The side of the tower is inverted Y-shaped. The elevation of the sling is arranged with fan-shaped dense cables. The inclined sling area is separated in the middle. The tower columns above the bridge deck are inverted Y-shaped and consolidated with the bridge deck and the double row piers under the bridge. The bridge deck is a prestressed concrete structure. The middle part is a three chamber thin-walled reinforced concrete box, and cantilever T-beams and box girders are set on both sides. The tower columns and double piers are hollow thin-walled reinforced concrete Concrete structure. The main section of the bridge is a two-way six lane urban expressway, which adopts the first-class highway standard.

 

Design parameters

The total length of Haiyin bridge is 1130.75 meters, the total length of main bridge is 416 meters, the span combination is 85.5 meters + 175 meters + 85.5 meters, of which the main span is 175 meters, the north and south side spans are 85.5 meters; the height of two pylons is 56.4 meters; the transition hole is 35 meters; the width of bridge deck is 35 meters, the height of cantilever T-beam and box beam on both sides is 3 meters, the width of central divider divided by bridge deck is 4 meters, the width of fast lane on both sides is 7.5 meters, and the width of slow lane is 5.5 meters A total of 186 stay cables with horizontal angle varying from 27 to 62 degrees are arranged on the bridge, with cable length ranging from 37.4 to 101.4 meters, outer diameter ranging from 179 mm to 202 mm and weight of 500 N per meter.

 

 

 

Equipment and facilities

Lighting facilities

The lighting of Haiyin bridge is divided into four parts: the first part is the lighting of the steel cable. The cable itself is painted red. According to the inherent characteristics of the bridge, the RGB full-color projection lamp is used to light the bridge cable in red to set off the facade of the bridge under the natural moonlight. Second, more than 800 full-color linear wall washing lamps are used on both sides of the bridge to illuminate the bridge body, and the flowing color light is used to express the image of water; whenever the boat is in the river, the colorful waves of water in the air flow against each other, bringing various carrier conditions into full play, giving people a sense of dynamic and static flow beauty. Thirdly, more than 80 high-power projectors are used to illuminate the facade of each pier, so as to facilitate the boat to see the bottom structure of the bridge from a distance and meet the lighting needs and landscape requirements. Finally, combined with the full moon shaped circular hole structure at the top of the bridge, 12 square projectors are placed in the bridge to create a full moon like crystal clear.

 

Monitoring equipment

As of April 2017, the whole section of Xinguang Bridge has been equipped with traffic monitoring equipment such as electronic police.

 

Operation

Ticket price

Since January 2001, Haiyin bridge has stopped charging and demolished charging facilities.

 

 

Traffic matters

Road restrictions

Since August 5, 2018, Guangzhou has implemented the management measures of "open four stop four". Haiyin bridge belongs to the restricted section of "open four stop four" in Guangzhou.

 

Construction achievements

Technical problems

The box girder of Haiyin bridge is constructed by double cantilever casting method with hanging basket. However, because the control load of stay cables of Haiyin bridge is construction load, it is an important problem to strictly control and reduce the construction load as much as possible in the design of hanging basket and the use of traditional Chinese medicine.

Travel

Haiyin bridge is one of the important scenic spots in Guangzhou Pearl River night tour,

 

Haiyin bridge lighting show is also one of the lighting works of Guangzhou International Lighting Festival.

 

Value significance

The completion of Haiyin bridge not only eases the tension in Guangzhou, but also adds a new beauty to the beauty of the city. < I (comments by Lin Peiyuan) < / I
