How many tunnels can the Guiguang high speed railway pass through in 3 minutes?

According to the experiment, this high-speed rail has to pass through a tunnel in less than a minute, so it has to pass through at least 3 or more in 3 minutes, which shows how difficult it is for high-speed rail to pass and the progress of science and technology.

Within three minutes, the Guiguang high-speed railway can pass through 5-6 tunnels, because the speed of the high-speed rail itself is very fast, and then the total length of the tunnels is not particularly long.

The length of the tunnel on the Guiguang high-speed railway line is very long, passing through nine tunnels in three minutes, and basically most of the time is passed through the tunnel.

The most "thrilling" trip! The Guiguang high-speed railway can pass through 9 tunnels in 3 minutes, and it takes less than 1 minute on average to pass through one tunnel.

In just three minutes, the Guiguang high-speed railway can pass through 9 tunnels, which is worthy of being called "a high-speed roller coaster flying in the mountains", and the whole process needs to pass through 238 tunnels.

On October 6, taking the high-speed rail to see China, the Guiguang high-speed railway took everyone to start the most "thrilling" trip. Nine tunnels were passed through in just three minutes from 9:10 to 9:13

82%, which is the bridge-tunnel ratio of the whole line of the Guiguang high-speed railway; 92%, which is the bridge-tunnel ratio of the Guizhou section of the Guiguang high-speed railway. This "super railway" travels through the mountains at a speed of 300 kilometers per hour, crossing the first in China.

The first and second tiers of the ladder span the Pearl River Delta, the Nanling Mountains and the Yunnan-Guizhou Plateau, passing through densely packed fault zones, high gorges and deep valleys and other ecologically sensitive and construction-intensive areas, passing through 238 tunnels and 510 bridges, known as "a high-speed roller coaster flying close to the ground in the mountains".

The Guiguang high-speed railway refers to the high-speed railway from Guiyang to Guangzhou, which will pass through about 464 kilometers of tunnels.

In fact, when it comes to the Guiguang high-speed railway, everyone will be familiar with it, I think many people have taken the Guiguang high-speed railway, and they will be shocked by the tunnels along the way. In fact, the Guiguang high-speed railway is an inter-district high-speed railway connecting Guiyang and Guangzhou in China, and the line of the railway runs from northwest to southeast, which is the southern part of China's "eight vertical and eight horizontal" high-speed railway network in the Lanzhou-Guangzhou corridor. Guiguang High-speed Railway, formerly known as Guiguang Railway, started construction on October 13, 2008, and was later renamed Guiguang High-speed Railway in 2010, and opened to traffic on December 26, 2014.

The Guiguang high-speed railway starts from Guiyang North Railway Station in the north to Guangzhou South Railway Station in the south, with a total length of 857 kilometers, 23 passenger stations and a train operating speed of 250 kilometers per hour.

The passenger stations along the Guiguang high-speed railway from north to south are Guiyang North Station, Guiyang East Station, Longdongbao Station, Longli North Station, Guiding County Station, Duyun East Station, Sandu County Station, Rongjiang Station and Congjiang Station in Guizhou, Sanjiang South Station, Wutong Station, Guilin West Station, Guilin North Station, Yangshuo Station, Gongcheng Station, Zhongshan West Station, Hezhou Station in Guangxi, Huaiji Station, Guangning Station, Zhaoqing East Station, Sanshui South Station, Foshan West Station and Guangzhou South Station in Guangdong.

In fact, the Guiguang high-speed railway is a "super railway", which spans the three provinces of Guizhou, Guizhou and Guangdong, with a total length of 857 kilometers, half of which runs underground, and a quarter passes through lava development areas, with a bridge-tunnel ratio of 83%. It is worth mentioning that the Guiguang high-speed railway is also the longest and most technically difficult railway line that has been built in China to cross lava sections. The number of new tunnels on the whole line of the Guiguang high-speed railway has reached an astonishing 238, and the total length of the tunnels has reached 464 kilometers, accounting for almost 54% of the total length, which can be said to be very amazing.

Among the Guiguang high-speed railway lines, the Yanshan Tunnel and the Sandu Tunnel are both more than 14 kilometers long, and they are both Class I high-risk tunnels.

According to Cao Zhenxing, chief engineer of the Guiguang high-speed railway, there are many problems to be overcome in the construction of this railway, especially when digging tunnels, and complex and changeable geological disasters such as rockbursts, fault fracture zones, and soft rock deformation, which are extremely risky. Regarding the first long tunnel, the "Yanshan Tunnel", Cao Zhenxing said: "The tunnel runs through a rocky mountain with 22 faults, and also crosses a river, which is less than 3 meters below the riverbed, and will break through if you are not careful.

In addition, because the area through which the high-speed rail line passes belongs to the karst landform, when the Sandu tunnel is excavated, it is necessary to pass through 14 large fault fracture zones, and encounter 65 large and extra-large karst caves, and the largest karst cave, the water inflow is as high as 150,000 cubic meters per day, which can be said to be very difficult to excavate.

The Guiguang high-speed railway is the first high-speed railway line connecting the Pearl River Delta and the western region in China, and this high-speed railway can greatly enhance the economic ties between the Pearl River Delta and the western region.

Huanggang Tunnel: The total length is more than 10 kilometers, and the stability is very poor, so it is also difficult to develop. Yau Zhu Shan Tunnel:

The total length is more than nine thousand meters. Tianpingshan Tunnel: The total length is 14 kilometers, and it takes three hours to reach the destination each time, and 50 meters must be detected each time it is only 10 meters under construction.

It can be said that all tunnel construction is very difficult.

"Guiguang high-speed railway" refers to the inter-district high-speed railway connecting Guiyang City and Guangzhou City. The total length of the Guiguang high-speed railway is 857 kilometers, and because the southwest is mountainous, the Guiguang high-speed railway has to pass through 238 tunnels.

"Guiguang High-speed Railway" is the abbreviation of Guiguang High-speed Railway, which connects Guiyang City and Guangzhou City, and has seven tunnels in total length. The total length of the Rock Hill Tunnel is 14 km.

"Guiguang high-speed railway" refers to the bullet train starting from Guiyang North Railway Station to the end of Guangzhou South Railway Station, with a total length of 857 kilometers, and this high-speed railway needs to pass through 209 tunnels with a total length of kilometers.

"Guiguang high-speed railway" refers to the railway connecting Guiyang City and Guangzhou City. The railway is 857 kilometers long, passing through more than 200 tunnels, with a total length of 464 kilometers, more than 54% of the total length.

Guiguang high-speed railway, which is the abbreviation of Guiguang high-speed railway, has seven tunnels in total length. The Rock Hill Tunnel: The total length is 14 kilometers, and it took four years to complete.

Sandu Tunnel: The total length is 14 kilometers, and the difficulty of opening up is as great as the Yanshan Tunnel, Liang'an Tunnel: The total length is 12 kilometers, which is prone to ** and water accumulation, and its ridge tunnel:

The total length is more than 7,000 meters, and the air is scarce.

High-speed rail refers to the abbreviation of Guiguang high-speed railway, his original name is Guiguang railway, there are 7 tunnels, the total length is 14 kilometers, the time to open this tunnel took a total of 4 years to complete

The railway connecting Guiyang City and Guangzhou City, referred to as the Guiguang Railway, has a total length of more than 850 kilometers, passing through more than 200 tunnels and more than 500 bridges.

For the completion of this railway, it will promote the economic exchanges between the two regions, can better promote the development of the economy, and facilitate our lives.

With a total length of 464 kilometers, the Guiguang high-speed railway line is the most difficult high-speed railway line to build in China, and the difficulty is almost comparable to that of the Qinghai-Tibet Railway. At the beginning, it was one of the most difficult key projects to cross a bridge.

Not to mention a falling object, not even a piece of paper can be blown over. Zhao Yao, chief engineer of the cable-stayed bridge project across Yansui Road of the Guiguang Nanguang Railway, said.

At the beginning, it was very difficult to build, and we knew that the tunnel was because there were too many mountains to build mountain roads, so we could only open holes in the mountains to build tunnels, and the mountains in this section were very hard and difficult to excavate.

Very large, such a long tunnel is not only very difficult to construct, the rock mountain tunnel geology is complex, there are rockbursts, fault fracture zones, soft rock deformation and other geological disasters, always need to worry about tunnel collapse

During the construction period, it is necessary to overcome the problems of rockburst and fault fracture zone, and also to construct under the river, which will break through the river if you are not careful, which is very difficult, and also reflects the maturity of China's infrastructure engineering technology.

The Guiguang high-speed railway does not pass through Sansui County. The Guiguang high-speed railway is led by the new Guiyang Station in the Daguan area between the Guijin Line and the Central Ring North Line on the east side of Jinyang High-tech Zone, Guiyang City, Guizhou Province, passing through Longli, wearing the cloak mountain to Duyun, and then entering the Guangxi Zhuang Autonomous Region along the Duliujiang River through the Rongjiang River and from the river. And did not pass by Sansui County.

The high-speed railway passing through Sansui is the Shanghai-Kunming high-speed railway, with Sansui Station, located in Gaozhai, Bagong Town, Sansui County, Guizhou Province, adjacent to Yuping East Station (Tongren South Station) in the upward direction, and adjacent to Kaili Shen Dry South Station in the downward direction. The station was put into operation on June 18, 2015.

The scale of Sansui Station is 2 sets and 4 lines, with a construction area of 6,000 square meters and a platform canopy of 8,500 square meters. There are 8 high-speed rail stops every day, which can go directly to Changsha, Nanchang, Hangzhou, Shanghai, Nanjing, Guiyang, Wuhan, Zhengzhou and other places.
