Takahashi, the first closure of beipanjiang River Bridge in the world is some 200 stories | beipanjiang _ news

Takahashi, world's first closure

A bridge across Yunnan, a thoroughfare. Vertical height of 565 m, equivalent to 200-story world Hang Rui Takahashi high-speed beipanjiang bridge (previously reported as zhuhe bridge, now known as the beipanjiang) have formal closure.

　　Opening of xuanwei, Yunnan province to liupanshui in Guizhou province from 5 down to 1 hour

Beipanjiang River is located in the junction of xuanwei, Yunnan and Guizhou shuicheng, across the yunguiliangsheng, total length of 1341.4 meters, deck to bottom of vertical height of 565 metres, becoming the world's first viaduct. Meanwhile, East and West on both sides of the main pier of the bridge height is 269 meters and 247 m, 720-meter main span is second only to late to start the construction of expensive (Yang), Guizhou (West) Highway in Yachi River Bridge, with a main span of the bridge span ranks second in the world.

Beipanjiang expects its operation by the end of this year, after the opening of xuanwei city of Yunnan province to liupanshui in Guizhou's drive from after about 5 hours, shortened to 1 hour.

Source on the beipan River are Xijiang River in the Pearl River basin in Red River's major tributaries, flows through Yunnan and Guizhou provinces, 449 km, total fall 1985 meters, 1000 meters average of 4.42 metres in length. Beipanjiang bridge since its construction, overcoming along the peaks of mountains, Valley aspect, complex geology, weather and other difficulties, ensure the high scientific and technological content and great difficulty of beipanjiang bridge construction into the finishing stage.

　　How to ensure accurate docking bridge at the time of closure?

　　Precise tuning to ensure that precise closure

Engineering and technical personnel at the scene said, when approaching closure, due to the construction process under the influence of factors such as temperature, wind, there can be deviations in the direction of vertical mileage bridge, horizontal axis deviation, deviations in the direction of vertical height, and angle of deviation.

Hang Rui high-speed overtime of beipanjiang bridge construction

Deviations on the vertical mileage, required to stretch on both sides of the bridge before the closure at a distance; for the adjustment of horizontal and vertical deviation, is focused on final closure; for angle deviation, you need to adjust the cable tension.

　　In the mountains for the first time by longitudinal shift cantilever hoisting technology

In the process of construction of the beipanjiang bridge, engineers and technicians in the mountains for the first time in the construction of large-span steel truss girder of cable-stayed bridge, using a longitudinal movement technology of cantilever steel truss girder erection.

This technology is 12 meters long and weighing 160 tons of steel truss girder on the ground as a whole when the stitching is complete, integral lifting by cranes and other equipment. In terms of duration, compared to traditional technology, a segment can save one or two days of duration.

In addition, because the steel truss segment is on the ground when the stitching is complete, then hoisting, compared to traditional mosaic in the air, and construction is more accurate, while factor are also higher.

　　See how much China Bridge cow!

Bridges in the world has this sentence: bridge in the 1970 of the 20th century saw the construction of the World Europe, 90 Japan, 21st century China.

Parrot island in Wuhan Yangtze River Bridge

Parrot Island 2.3 km upstream of the Yangtze River Bridge in Wuhan Yangtze River Bridge, the eighth Yangtze River Bridge of Wuhan, main deck for bidirectional 8 traffic lanes. This is the world's first consecutive three-tower suspension bridge for main cable, three towers of the bridge span in the world's largest four-span suspension bridge. On December 28, 2014 completed.

Pingtan Straits highway-railway dual-purpose bridge

China's first true highway-railway dual-purpose bridge--Pingtan Straits highway-railway dual-purpose bridge is under construction. This bridge also because "most difficult construction" is known in the bridge community. Location of the bridge is in one of the three high wind areas in the world, 6-level winds for more than 300 days a year, extremely harsh environment. Bridge a total length of 16 km. At present, the bridge from the new structures, new processes, new methods had been declared a 12 patents, to be called a creative bridge.

Chongqing wanzhou Yangtze River Bridge

Wanzhou Yangtze River Bridge formerly Wanxian Yangtze River Bridge, is a road bridge. This is a super highway connecting national highway 318 supporting the bridge, is the first single on the Yangtze River highway bridge over the River, is the world's largest span arch bridges of the same type. Full bridge 814 meters long, 23 meters wide, Arch NET span of 420 m, bridge deck 140 meters high from the river. Opening of the main bridge was completed in May 1997, was then and the largest reinforced concrete arch bridge with long span in the world.

Qingdao Bay Bridge

Qingdao Bay Bridge also known as the Bay Bridge, is the design, construction, construction of large-span bridge. 36.48-kilometre bridge, invested nearly 10 billion, took 4 years to complete.

世界第一高桥北盘江大桥合龙 相当200层楼高|北盘江大桥_新闻资讯

世界第一高桥合龙

　　一桥跨云贵，天堑变通途。垂直高度565米，相当于200层楼高的世界第一高桥杭瑞高速北盘江大桥（此前报道称其为尼珠河大桥，目前定名为北盘江大桥）已正式合龙。

　　通车后云南宣威到贵州六盘水从5小时减为1小时

　　北盘江大桥坐落于云南宣威与贵州水城交界处，横跨云贵两省，全长1341.4米，桥面到谷底垂直高度565米，成为目前世界第一高桥。同时，大桥东、西两岸的主桥墩高度分别为269米和247米，720米的主跨也仅次于后期开工建设的贵（阳）黔（西）高速公路鸭池河特大桥，在同类型桥梁主跨的跨径中排位世界第二。

　　北盘江大桥预计今年年底通车，通车后云南宣威城区到贵州六盘水的车程将从此前的5个小时左右，缩短为1个多小时。

　　北盘江是珠江流域西江上源红水河的大支流，流经云南、贵州两省，全长449公里，总落差1985米，1000米长度平均降低4.42米。北盘江大桥自开工建设以来，克服了沿线山峦叠嶂、沟谷纵横、地质复杂、气候恶劣等重重困难，确保了科技含量高、难度大的北盘江大桥建设顺利进入收尾阶段。

　　如何确保桥梁在合龙时精准对接？

　　精确调校确保精确合龙

　　现场的工程技术人员表示，临近合龙时，由于施工过程中受到气温变化、风力等因素的影响，大桥可能会存在纵向里程方向的偏差，横向轴线方向的偏差，竖向高程方向的偏差，以及转角的偏差。

杭瑞高速北盘江大桥加班施工

　　关于纵向里程方向的偏差，需要在合龙前将大桥向两岸拉伸一段距离；对于横向和竖向偏差的调整，则主要在合龙口进行；对于转角偏差，需要通过对缆索的拉力进行调整。

　　在山区首次运用纵移悬拼技术吊装

　　在此次北盘江大桥的建设过程中，工程技术人员首次在山区大跨度钢桁梁斜拉桥施工中，运用了纵移悬拼技术对钢桁梁节段进行吊装。

　　这种技术是把长达12米、重160吨左右的钢桁梁节段在地面整体拼接完成后，通过吊机等设备进行整体吊装。在工期方面，比起传统的工艺，一个节段可以节约一到两天的工期。

　　除此之外，由于钢桁梁节段均是在地面拼接完成后，再进行整体吊装，对比传统在空中拼接的工艺而言，施工精度更高，同时安全系数也更高。

　　看看中国的桥有多牛！

　　在世界桥梁业有着这样一句话：世界桥梁建设20世纪70年代以前看欧美，90年代看日本，21世纪看中国。目前，“中国桥梁”，已经成了中国的一张亮丽名片和彰显综合国力的重要符号。一起来看看！
