Heishan high -speed opening, Chinese infrastructure overseas another 1 point

Produced | NetEase News

Introduction: At Podogolcha, the capital of Heishan, people watched fireworks performances at the opening ceremony of the North -South Expressway in Heishan. This highway is undertaken by China Road and Bridge Group, and it has become the local "Century Project" as soon as possible. Traffic source.

I don't know when it started, my country's strong infrastructure strength began to deeply root the hearts of the people. The ancient and youthful industry of civil engineering, accompanied by people step by step towards a happy and beautiful life. A Xinhua News Agency reporter set off from Beijing by high -speed rail. It can reach 54 cities in just half a day, and this is just a microcosm of my country's infrastructure strength.

1. The first highway of Heishan History comes from "Construction of China"

According to the data of the Ministry of Transport, from 2012 to 2022, the increase in the mileage of my country's railway and highways was about 1.1 million kilometers, which is equivalent to bypassing the Earth equator 27 and a half, high -speed railway and highways. The coverage rate of cities exceeds 95%. Behind this great development, construction machinery and equipment are constantly developing, new infrastructure technology is constantly emerging, and our infrastructure strength has also established the position of world leaders. To this end, people gave him a title -"Infrastructure Magic".

After winning the crown of many worlds, we did not stop there. Instead, we put our attention overseas, leading the progress of global infrastructure development from a more civilized perspective. Not only the condensed Chinese power behind the China -Lauding Railway stunned the world, the Central Business District (CBD) in the African desert, the green power plants along the Mediterranean coast, and the future city on the Indian Ocean ... In fact, in many overseas treasure -level infrastructure projects , Can see Chinese figures frequently.

Montenegro is located in the southwestern part of the Balkan Peninsula in Europe, with an area of ​​13,800 square kilometers and a population of 622,000 (2019). Deelia Sea. On July 13th, it was the National Day of Heishan. On this day, the Grand Opening Ceremony was held in the priority section of the North and South Expressway projects of Heishan.

Heishan North and South Expressway are the greatest construction projects in the history of the Republic of Heishan. It will bring a more comfortable and faster transportation experience to the local people. From the south of the highway, Balt, Balt, to the border city of Heishan and Serbia, Boliare, with a total length of about 180 kilometers.

If you want to be rich, cultivate the road first, such a concept has been deeply printed in the minds of the people, but there are many countries abroad but still endure the pain caused by inconvenience. Before the highway was opened, the mountainous areas, especially the northern mountainous areas, were extremely inconvenient, and the phenomenon of mountains and stones rolled endlessly.

Although local norms often attract people's travel under the slogan of pure ecology, this is actually a compromise that cannot develop the industrial economy due to inconvenient transportation. As we all know, the relative occlusion environment cannot support economic development and life progress. Over the years, the people of Heishan have also been eagerly looking forward to a highway that can have their own citizens. Therefore, this highway built by China Road and Bridge Group is also called "Century Project" by locals as the "Century Project".

2. Seven years of tackling, we have repeatedly broke the record

The entire construction period of the North and South Expressway of Heishan is 7 years long and the high -speed main road is 180 kilometers in length. Among them, the Smokovaz -Mataihevo section is in the stage of priority construction. There are 16 tunnels and 20 bridges in the Smokavatz -Mataihevo section, including 3 interchange interchange, which has become the largest section of the North -South highway technology and construction, with a bridge tunnel ratio of 60%. The ratio of Takahashi Tunnel also reflects the difficulty of construction from the side. Compared with the peaceful roads, the construction of a bridge tunnel always takes more time and energy.

The project set a number of Chinese companies in similar European projects: an altitude of more than 2000m, the most complex geological conditions, and a bridge -tunnel ratio of up to 60%. The project section span two climate bands and two geological bands. The first 22 kilometers are the limestone areas of the Mediterranean climate, and the last 19 kilometers are the reinforcement area of ​​the temperate continental climate. The complexity can be imagined.

In the face of difficulties, the project responsible team did not shrink. Under the condition of short construction period, how to unite the Chinese and foreign teams to play the maximum cooperation force became the top priority at that time. Although domestic engineers are experienced, they do have various restrictions overseas, which put forward various requirements for local support capabilities. You must know that language differences are natural, especially in key links such as technical intercourse, drawing review, and material supply often consume a lot of time. The scenes that the two parties are pulling each other greatly reduce the efficiency and speed of work. In the face of this situation, the project team actively organized local partners to study in China. After the knife was cut, the firewood workers were cut by mistake. After spreading the experience in the construction of advanced roads and bridges in China, the engineering concepts of the two parties naturally reached an agreement. After detailed communication and coordination, they jointly selected the optimal solution, which also laid the foundation for overcoming one -time technical difficulties.

Third, respect nature, green construction opens a new chapter in the domestic road base slope removal rate, and can be directly used to protect grass. Other slopes mostly use concrete skeleton protection, and the protection effect is better. However, for countries with high requirements for insured landscapes, standardized standards are not allowed to apply a large amount of concrete to the protection of road base edge. And as a highway construction project, the cost of land acquisition is relatively high. In order to reduce the land occupation, the slope cannot slowly slow down to a stable state, so protective measures are indispensable.

Based on specifications, as a substitute for concrete skeleton protection, the Kuroshan North and South High -speed project road base slope uses a large number of protection forms of anchors+ hanging nets. This kind of protection measures can greatly reduce the use of workers, and the landscape greening after spraying in the later period is green The effect is better, and the environmental benefits are very prominent.

The opening site of the Kurishan North and South Expressway

The environment near the North and South Expressway of Heishan is beautiful. A three -kilometer -long tunnel is like a gate. You can cross from one climate area to another. The two ends of the tunnel have completely different temperatures, soil forms and plant types. Under such circumstances, environmental protection is also a "test papers" that the construction unit must work hard.

To this end, the China Road and Bridge team has established a comprehensive environmental protection system and working regulations. Under the guidance of supervision engineers, environmental experts, and relevant government departments, the project has obtained a total of 53 environmental permits. During the construction process, regular test testing of air, water, camp wastewater and tunnel wastewater, soil and noise to ensure that environmental protection work meets the EU in line with the EU And Heishan laws and regulations require.

After the opening of the priority section, local residents were very excited. This is the first time they have boarded a highway belonging to their own country since their lives. However, because the promotion and guidance of high -speed safety driving in the early stage was insufficient, there were many violations of driving incidents. On the first day of the opening of the local TV station RTCG, some drivers smoked and rest in high -speed tunnels. No safety accidents occurred.

Protection before the opening of the highway

Milan Ljiljanic, the person in charge of the Heishan government in charge of transportation construction, also complained that his compatriots were "serious lack of traffic culture." A few days later, after the report of the TV station, the public gradually adapted to the rules of highways.

At the same time, the project department has designed solid traffic safety facilities for the highway according to relevant specifications and requirements, providing systems, comprehensive instructions, warnings, bans and other information for highway users, inducing sight, excluding glare and other interference, protecting and protecting glances, protecting glances, etc. The road side is safe.

Conclusion:

This project is the most important infrastructure project in Heishan for decades and the first highway in the history of Heishan. Its official opening date will be included in the history book. It will become the beginning of the permanent connection between Heishan and the world, and the hills of the Mountain Karst Mountains will be connected to the fertile plain. After the priority of the Heishan North and South Expressway project was put into operation, many Heishan people lamented: We will no longer encounter long lines long behind the truck, or recklessly in the middle of the curve. This truly brings well -being to the local people.
