五峰山公铁大桥即连淮扬镇铁路五峰山长江大桥，是继1968年建成的南京长江大桥之后的长江江苏段第三座公铁两用大桥，是八车道高速公路和[ 2] Fourth -line high -speed railway cross -riverside large transport comprehensive railway channel. Zhenjiang Yangtze River Bridge is a key node project connecting the Lianhuaiyang Railway and Beijing -Shanghai Highway South Extension. It is designed by the China Railway Bridge Survey and Design Institute. The national engineering design master and the famous expert of my country's suspension bridge Xu Gongyi as the chief designer. Starting in design work in 2008, in January 2016, the main structure of the bridge was fully launched.
Wufeng Mountain Yangtze River Bridge was located between Taizhou Yangtze River Bridge and Runyang Bridge . The south bank is located at the foot of Mountain, , .
Wufeng Mountain Yangtze River Bridge has four world records: First, the world's largest public iron dual -use suspension bridge (1092 meters); second, the world's largest graphic design size of the north anchor sink (101 meters long, 72 meters wide, 72 meters wide, 72 meters wide, 72 meters wide, 72 meters wide 56 meters high); third, the world's number one suspension bridge; the fourth is the world's number one railway bridge (250 kilometers per hour). After the
project is completed, the bridge will become China's first railway suspension bridge, and it is also the world ’s load and speed railway suspension bridge. Nan Beizan Bridge (its span is 1100 meters, the upper floor is a four -lane road, and the lower floor is the dual -line railway at the speed of 180 kilometers per hour).
"World No. 1"
Wufeng Mountain Yangtze River Bridge is 100.7 meters long, width of 72.1 meters, and 56 meters high. The largest aircraft carrier in the world is full of displacement, and the volume and weight are "the world's first well." After sinking into the design elevation, the sinking of the bridge relies on the self -heavily pulled the bridge to support the bridge surface. After repeated research and attempts of
, the builders have adopted the cross -sinking, digital sinking, air screen, three -dimensional sound detection stereo imaging and other technologies to ensure that the Wuding Mountain Bridge sinking plane error is controlled at 10 at 10 Within centimeters, the accuracy is much higher than design and specification requirements.
is 136 meters away from Shenjing. There is a 110 kV cross -river high -voltage electric tower built in the 1960s. It is 180 meters from Shenjing. Once a settlement occurs, the safety of the electric tower and the river embankment will be severely threatened, and the consequences will be unimaginable. During the sinking process of Shenjing, the project department of the Second Airlines Bureau immediately adopted the means of real -time monitoring, closely pay attention to the changes in surrounding clues, and accurately control the sinking speed to ensure the safety of crossing the Jiangdian Tower and the Yangtze River embankment.
What is a suspension bridge anchor?
anchor is an important structure of the ground anchor suspension bridge. The tension in the main cable passes through the foundation through the anchor, and stabilizes one end of the main cable on the anchor. The anchor is usually poured underground large concrete blocks, and anchor is also anchored in the mountains. The
suspension bridge is a bridge of the cable or chain of the tensile force as the main load -bearing component. It consists of suspension, Sota , anchor, boom, bridge deck and other parts. The main load -bearing component of the suspension bridge is suspension. It is mainly used for pulling force. Generally, it is made of steel (steel wire, steel cable, etc.) with high tensile strength. Because the suspended cable bridge can make full use of the strength of the material and has the characteristics of province and self -weight, the suspension bridge has the largest leap capacity in various system bridges, and the span can reach more than 1000 meters.
