The moat became a thoroughfare. What happened in qingshui river bridge, Guizhou?

On the Qingshui River in the middle of Guizhou Province, an expressway bridge flies between two mountains, turning the natural moat into a thoroughfare. This expressway is Guiweng Expressway.

20 15 12 3 1 With the opening of Guiweng Expressway, all 88 counties and cities in Guizhou Province have opened expressways, achieving the goal of "expressway connecting counties".

Since then, this once mountainous plateau has become a "plain" extending in all directions, and these expressways not only connect the mountainous area with the outside world, but also connect the hearts of people of all ethnic groups in the mountainous area.

Qingshui river bridge turned the natural barrier into a thoroughfare.

As we all know, traffic congestion is an important reason for the lack of development in Guizhou. There are many mountains in Guizhou Plateau, known as "eight mountains, one water and one field", and it is the only province in China without plains.

It's hard to get through the Shu road, but it's even harder to get through the main road.

Guizhou is a typical karst landform with complicated geology and karst caves everywhere. Under such geological conditions, large drilling rigs cannot be used, and only the most primitive manual digging holes can be used; Nine times out of ten, piling will encounter caves, and more than 1000 concrete will be poured down, and it will be gone in an instant; Without transportation roads, the "big" materials needed for bridge construction can neither be brought in nor stored anywhere; The weather conditions are bad, foggy and rainy, with rain and snow accounting for 70%.

This terrain environment requires the construction of expressways, which sets difficult conditions for builders.

What is amazing, however, is that since the "Three-year General Conference War on Expressway Construction" was launched in Guizhou on 20 13, Guizhou has made every effort to crack the traffic bottleneck with the courage to tackle the problem, the momentum of the battle and the confidence to win. These new expressways, represented by Guiweng Expressway, are completely unaffected by the harsh natural environment. With the innovative wisdom and spirit of the builders, the project has made rapid progress. Even qingshui river bridge, which is located in Guiweng Expressway, can finish the task ahead of schedule under the condition of high construction difficulty. Guo, chief engineer of CCCC Guiweng Expressway Co., Ltd. (hereinafter referred to as Guiweng Company), told the reporter: "The construction time in qingshui river bridge is 40% shorter than that of bridges of the same size."

The qingshui river bridge, which is called "the second Gao Qiao in the world" by the British media, is expected to take at least four to five years, but the speed is unbelievable-it took only 29 months from the start of construction to the opening of the car, a whole year ahead of the planned construction period.

"Only consider the method of success, not the excuse of failure."

This slogan hanging horizontally on the 100-meter pier is probably the secret of the high-level and rapid completion of the project by the builders of Guiweng Expressway.

"Up to now, qingshui river bridge has applied for more than 40 national patents for engineering design and construction, and more than 20 are preparing to apply."

Zhang Mingshan, chief engineer of Guiweng Expressway qingshui river bridge Project, told the reporter, "In order to solve the problem of efficiency in transporting materials, the bridge used a kilometer-class large-tonnage cable crane for the first time. This innovative technology has shortened the construction period of the bridge by about 7 months. "

"Everything is centered on the scene, and no one can hold back." Wang Fengcun, the project manager of qingshui river bridge, often uses this sentence to unify the thoughts of the staff of the project department. The whole project department is like a set of gears that are closely meshed and push each other. The materials, equipment, technology and logistics departments are running at high speed, and finally this seemingly impossible task has been completed.

Qingshui river bridge was opened to traffic one year ahead of schedule, setting a new height and speed in the history of bridge construction in China.

"Many of us here have never seen the other side of the mountain for generations, and the expressway has made our dreams come true."

On the last day of 20 15, Chen, a Miao girl, and dozens of Miao, Buyi and Tujia girls dressed in costumes gathered at the newly-built Qiaotou in qingshui river bridge, vying for a group photo.

Recall that before the road was built, although the straight-line distance between the hills on both sides of Qingshui River was only 1 km, it was not easy to walk-Yuan, who lives in Baisha Township, had to go down to the bottom of the river along the narrow path every time he crossed the other side, then crossed the river by ferry and climbed up from the bottom of another mountain along another narrow path. The journey took at least two hours.

After the completion of qingshui river bridge, the journey takes only 3 minutes. At the same time, with the opening of Guiweng Expressway, the distance from Guiyang to Weng 'an has been shortened from the previous 4 hours to 1 hour. It is no longer difficult for people on both sides of Qingshui River to travel, which makes them closer to the world outside the mountain.

Traffic congestion is an important reason why a considerable number of people in Guizhou are poor. The opening of expressways has not only injected new opportunities and vitality into the economy and culture of counties in the province, but also narrowed the distance between counties, counties and cities and Guiyang, changed the situation of external traffic congestion, strengthened the contact between poor people and the outside world, made agricultural products more commercialized, broadened farmers' income channels and increased farmers' income steadily.

The construction of expressways has revitalized the economy in mountainous areas.

"After the Guiyang-Guizhou Expressway is opened to traffic, it will run through Guiyang, Weinan and Tongren in 5 minutes. Maoyun Township has been transformed into the' South Gate' of Kaiyang and the' bridgehead' of Guiyang leading to southern Guizhou. " A Hong Kong investor said.

Weng 'an County, which is close to Guiweng Expressway, has also become the "fragrant cake" of major enterprises. "Weng' an has the resource advantage of phosphate fertilizer. After the high-speed traffic, our logistics cost can be reduced by 20 yuan per ton. "The person in charge of Jin Zhengda said that the high-speed traffic will reduce the cost of Jin Zhengda by nearly 60 million yuan every year.

At present, eight towns along Guiweng Expressway have started a new round of economic layout and set off a new climax of industrial development.

Guizhou road is difficult, and Guiweng Expressway above Qingshui River is difficult.

Qingshui river bridge was built in an incredible 29 months.

Over the past five years, China has built more than 30,000 kilometers of expressways, with a total mileage of 6,543.8+0.3 million kilometers, ranking first in the world. The completion and opening of these expressways has facilitated people's lives, revitalized the local economy and laid a solid foundation for the realization of the "Belt and Road" concept and the Chinese dream.

The builders of China not only wrote heroic hymns, but also staged scenes of joys and sorrows. In them, we can not only see the determination and courage to overcome difficulties, but also shine with the wisdom and ability to solve problems. They are the pavers of a better life for people of all ethnic groups and the practitioners of realizing the great rejuvenation of the Chinese dream. They built the access not only on the land of the motherland, but also in the hearts of people of all ethnic groups!
