Wai Bai Du Bridge

The outer white bridge, erected at the confluence of Suzhou River and Huangpu River in Shanghai, is a steel structure under construction bridge. It is the largest steel bridge in Shanghai.

The outer white bridge has a history of 100 years, carrying the historical culture of old Shanghai, and witnessing the change rapidly in new Shanghai. It can be seen in many old Shanghai TV dramas, which can prove its position and significance in Shanghai.

To enjoy the bridge, you need to stand in the distance to have a panoramic view, stand on the bridge to have intimate contact, and enjoy the scenery on both sides of Suzhou River. If you are lucky, you may be able to see the new couple playing with photography, taking advantage of the red light and no car to take personalized and unique wedding photos on the bridge.

Construction process

In the six year (1856) of Qing Xianfeng, in 1856, the first generation of Wai Bai Du bridge was built, called the "Wells bridge", with movable bridge deck in the middle. Pedestrians need to pay "bridge tax" before crossing the bridge

.

In 1873, a wooden floating bridge was built near the Welsh bridge, which was named "Park Bridge" because it was adjacent to the Bund park. On July 28, the park bridge was completed

.

In 1906, the park bridge was repaired several times, which could not meet the needs of traffic development. The Ministry of industry decided to build another steel bridge instead. In the same year, the construction of Wai Bai Du Bridge

.

In the thirty-three year (1907), the white bridge was built and put into operation.

.

In 1947, the Shanghai municipal government carried out a large-scale maintenance to prevent the bridge from further sinking

.

In 1964, the outer bridge was rebuilt, the original tram tracks were removed, and the reinforced concrete deck was rebuilt.

.

In August 1991, the municipal department repaired the truss structure and supporting platform of the white bridge.

.

In March 2008, the outer white bridge was closed to traffic. Apart from the pier, it was removed from the original site and sent to the Shanghai shipyard for major repairs.

.

In March 2009, the Wai Bai Du bridge returned to its original position.

. In March 31st, the first lighting test was conducted at Wai Bai Du bridge.

Architectural design

building structure

Wai Bai Du bridge is a simply supported steel truss bridge. It is also a steel riveted bridge and an unequal high truss bridge with two holes. The upper part of the outer white bridge is a simply supported riveted steel honing frame. The lower timber pile foundation reinforced concrete abutment and the concrete hollow slab pier bridge support the upper bottom supported tubular riveted steel truss, and the lower part is wood pile foundation reinforced concrete abutment and concrete hollow slab bridge pier.

.

Design parameters

As of January 2020, the whole bridge of Wai Bai Du bridge is 104.24 meters long.

The span and longitude combination of the two holes are 52.178 m each

The highest truss is 9.144 M

The beam bottom elevation is 5.75m

It is 18.4 meters wide, 11.2 meters wide, 3.6 meters wide on both sides of the sidewalk. The total weight of the bridge is about 900 tons and the load is 20 tons

. The bridge has 11 nodes, each of which is 4.744m long

Equipment and facilities

lighting

In March 31, 2009, the "light of the city" lighting system began to test the lights. The lighting system of "city light" adopts full-color LED lamps. There are chips of red, green and blue in the lamps. The different proportions of the three colors are adjusted by the computer in the control center, which not only presents a variety of colors, but also reduces energy consumption. The lighting is divided into two modes: normal mode and festival mode. The main color of normal mode is warm yellow. In holidays or some important activities, the lights will become a variety of colors to create an atmosphere and echo with the night lights in Pudong

Operation

Ticket price

From 1876 to 1907, there was no charge for pedestrians crossing the park bridge

 

 

.

Since 1907, Wai Bai Du bridge has replaced the park bridge as a part of the municipal road.

 

.

Traffic matters

As of January 2020, during the national day, new year's Day holidays and other holidays, traffic control was implemented at Baidu bridge.

 

.

traffic flow

From June 14 to 16, 1889, from 8 a.m. to 8 p.m., a total of 35311 pedestrians (including 33666 Chinese and 1645 foreigners), 1633 carriages, 20958 rickshaws, 22 vans, 2759 small cars, 38 horses and 27 sedans passed through the park bridge

 

.

In May 1926, 17 and 18 two, from 7 a.m. to 7 p.m., forenoon bridge averaged 50823 passengers per day, 14600 rickshaws, 4999 cars, 172 buses, and 922 trams.

Construction achievements

Technical problems

Foundation reconstruction

The reconstruction of the foundation of Wai Bai Du bridge is complicated and difficult to construct. However, due to the combination of steel shell caisson and the castor pile, the new bridge substructure only has a 3 millimetre rise after the shield passes. Although the method of cast-in-place pile has many shortcomings, such as high engineering cost and many difficulties in construction, the over rotary drilling machine has the dual functions of removing obstacles and forming holes, and has the characteristics of high vertical precision, small vibration and short construction period. The problems such as pile bottom uplift, reinforcement cage sinking, casing and pile pulling out at the foundation reconstruction of Baidu bridge are solved by increasing casing sinking depth, casing pressure water, retaining 30-50 cm soil bottom, reinforcing steel cage bottom and steel plate, welding crane block and surface fixation.

Protection and repair

The repair technology of white tiger on Wai Bai Du bridge is various, including water work, shipping, hoisting, steel structure, riveting, cofferdam, steel shell caisson and clearance. It is the key to ensure the smooth progress of the whole project that whether the construction sequence and process can be reasonably arranged between the various processes, so that they are closely linked and do not affect each other. The construction period of Wai Bai Du bridge is only 13 months. The construction technology of the upper and lower structures must be carried out more. At the same time, the construction area is small and must be properly arranged to ensure that the key nodes are completed on schedule. As one of the landmark buildings and the landmark buildings in Shanghai, the outer white bridge has been highly concerned by all sectors of society. The project involves a wide range of areas and requires higher coordination and organizational capabilities.

 

. The steel truss "ship moving method" was adopted by the construction company to transport the whole bridge to Shanghai Shipyard for overhaul. In March 2009, the Wai Bai Du bridge returned to its original position.

Cultural characteristics

City symbol

From 30s and 40s twentieth Century to early twenty-first Century, the symbol of the Wai Bai Du bridge frequently appeared in film and television works. In the 1930s and 1940s, there were "the angel of the road", in the 1950s and 1960s, there were "unite to tomorrow" and "Nie Er". After the reform and opening up, there were many films and TV works, such as "Ruan Lingyu", "Shanghai Rumba", "Suzhou River", "little things in the big city", "legend on the sea", "east wind and rain". However, the construction of the outer white bridge through the works of "little time" and "giant toothed shark" in twenty-first Century has emerged from many Shanghai buildings and has become a symbol of Shanghai. This symbol is also used in the "propaganda film of Shanghai applying for the World Expo" before and after 2010 and the "propaganda film of Shanghai entering the World Expo" in 2018
