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 the Bay Bridge in Sydney, Australia, has the function of sightseeing. Different from nanpu bridge and Yangpu Bridge, Lupu Bridge, the first arch in the world, installed the sightseeing platform on the top of the arch rib like a giant bow, which not only made the sightseeing height higher, but also required tourists to follow the "slope" of the arch rib.
Walking sightseeing on the slope of Lupu Bridge requires more than 300 steps, which increases 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, which was officially completed and opened to traffic on June 28th, 2003, is the first all-steel arch bridge on Huangpu River and the largest steel arch bridge in the world today, with high technical content, strict accuracy requirements and great construction difficulties. 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".
1? The world's largest arch bridge spans 550 meters, which is 32 meters longer than the original West Virginia Bridge in the United States.
2? The world's first super-large arch bridge with box arch structure, with a main section of 9 meters high and 5 meters wide, is the largest in the world.
3? At present, the first large-scale arch bridge in the world is connected by welding technology except that one end of the joint is fixed by bolts. The total length of on-site welds exceeds 40,000 meters, which is close to the total length of Shanghai Inner Ring Elevated Bridge.
4? In the process of arch bridge construction, the hoisting weight of a single member ranks first 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 architecture combines three different types of bridge construction technologies: cable-stayed bridge, arch bridge and suspension bridge. 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.
7? During the whole construction process of the main bridge, the steel consumption for construction measures reached more than 1. 1 10,000 tons, which is the largest bridge for single arch bridge construction measures in the world at present.
8? The 16 horizontal tie-bar cable used in bridge construction is the longest (760m), the thickest (18cm), the heaviest (1 10t) and the largest tensioning tonnage (1700t) among the arch bridges in the world.
9? On-site steel plate welding thickness 100 mm is the highest in steel structure bridge construction in the world.
10? In the process of bridge construction, many large-scale mechanical equipment and large-scale temporary construction facilities are used, which is the largest one used in the reconstruction of single bridge in the world at present.
