designer
Lin Yuanpei, a native of Putian, Fujian, male, is a famous bridge expert in China. 1954 graduated from Shanghai Civil Engineering School. He used to be the chief engineer of Shanghai Municipal Engineering Design and Research Institute and the deputy director of china civil engineering society Municipal Society. He is currently the senior chief engineer of Shanghai Municipal Engineering Design and Research Institute. In 2005, he was elected as an academician of China Academy of Engineering. In 2007, he won the Science and Technology Achievement Award of Heliang Lihao Foundation. 1989 was named as the first batch of "China Engineering Design Masters" by the Ministry of Construction.
He is the representative of the 15th CPC National Congress. Shanghai Tenth People's Representative, Shanghai Top Ten Scientific and Technological Elites, Shanghai Top Ten Construction Heroes and Shanghai Science and Technology Heroes have been rated as Shanghai Model Workers for many times, and 1995 was rated as the national advanced worker. Because of its outstanding contributions and achievements in bridge construction technology in China, it was awarded the national design master and won the 1994 Mao Yisheng Bridge Award. He is the chief designer of nanpu bridge, Yangpu Bridge, Xupu Bridge, Lupu Bridge and Donghai Bridge.
Bridge scale
The Lupu Bridge, which started construction on June 25th, 2000, starts from Luban Road in Puxi in the north, crosses Huangpu River and ends at Jiyang Road in Pudong in the south, with a total length of 3.76 kilometers. The main bridge of this bridge adopts all-steel structure. The direct approach bridge of the bridge is 3900 meters long, of which the main bridge is 750 meters long and 28.75 meters wide, and it adopts the way of crossing the river. Because the main span reaches 550 meters, it ranks first among similar bridges (steel arch bridges) in the world. The main bridge is designed with six lanes, and the approach bridge is designed with six lanes and four lanes. The design channel has a clearance of 46 meters and a navigable width of 340 meters. The cross section of the main arch is the largest in the world, with a height of 9 meters and a width of 5 meters. Ships of 70,000 tons can pass under the bridge. It is also the world's first large-scale arch bridge completely connected by welding technology. With a total investment of more than 2 billion yuan, the project was completed and opened to traffic on June 28, 2003. On May 1 day, 2007, Lupu Bridge was first lit.
The bridge is beautifully curved, such as Changhong lying in waves and flying to Pujiang. Lupu Bridge adopts three different bridge design technologies: cable-stayed bridge, arch bridge and suspension bridge. It is the bridge with the most complicated construction technology and the most steel consumption in the construction of single bridge in the world.
Lupu Bridge, like Sydney Bay Bridge in Australia, has the function of sightseeing. Different from nanpu bridge and Yangpu Bridge, Lupu Bridge, the world's first arch, installed the sightseeing platform on the top of the arch rib, just like a giant bow, which not only made the sightseeing height higher, but also required tourists to walk more than 300 steps along the "slope" of the arch rib before sightseeing, which increased the sightseeing, interest and sports. Tourists take the high-speed sightseeing elevator to reach the deck of Lupu Bridge, which is 50 meters high, climb the steps along the sidewalk of the arch rib of the bridge, climb the back of the "Giant Bow" for about 280 meters, climb the top of the arch rib with the height of 100 meters, and stand on the sightseeing platform the size of a basketball court overlooking the beautiful scenery of Pujiang. Because Lupu Bridge is located on the central axis of the Expo site held in Shanghai on October 20, 2000, the "laurel crown" embedded in the arch rib of Lupu Bridge-the sightseeing platform at the top of the arch rib will be the best scenic spot to have a bird's eye view of the Expo site yesterday, today and tomorrow.
Shanghai Lupu Bridge, officially opened to traffic on June 28th, 2003, is the first all-steel arch bridge on Huangpu River and the second largest steel arch bridge in the world. High-tech content, strict accuracy requirements and difficult construction. It marks a major breakthrough in bridge technology in China and the level of bridge construction has jumped to a new level. Lupu Bridge, like a beautiful rainbow, spans the banks of Pujiang, adding a new landscape and symbol to Shanghai. This bridge also created 10 "the best in the world".
Best bridge
1, the world's largest steel box arch bridge, with a span of 550 meters, which is 32 meters longer than the former world's largest West Virginia Bridge in the United States;
2. The world's first super-large arch bridge with box arch structure, the main arch section is 9 meters high and 5 meters wide, which is the highest in the world;
3. The world's first large-scale arch bridge, all of which are connected by welding technology except one end closed, has a total length of more than 40,000 meters, which is close to the total length of Shanghai Inner Ring Elevated Road;
4. In the process of arch bridge construction, the hoisting weight of a single member is the heaviest in the world, reaching 860 tons, and the maximum total hoisting amount of arch ribs crossing the river is 480 tons, ranking first in the world;
5. The main bridge construction is the combination of three different types of bridge construction technologies: cable-stayed bridge, arch bridge and suspension bridge, and it is the most complicated bridge in the world at present.
6. The steel consumption of the whole main bridge structure is more than 35,000 tons, which is equivalent to the steel consumption of three 74,000-ton ships, and it is the largest single arch bridge in the world at present;
