In 2022, it was the 70th anniversary of the establishment of the CPIC. Over the past 70 years, the Second Court of China Railway has started from the Chengdu -Chongqing Railway and rooted in southwest transportation. The historical accumulation and brilliant performance achievements are admirable. It is full of innovative responsibilities here, and people are always struggling. In the seventy years, the three generations of the three generations are unsuccessful. The people of the Second Hospital have a consistent spirit of innovation, taking the role of my responsibility, and writing the immortal legends in the history of transportation development.

Seventy years, three generations

In 70 years, from the Puchai Railway at a speed of 450 kilometers per hour, to a high -speed railway with a speed of 350 kilometers per hour, the Chinese railway construction has achieved a large leap, and China's high -speed rail mileage has ranked first in the world. This magnificent history of railway development, China Railway Second Hospital is not only a witness, witness, but also participants and recorders.

As of now, the domestic railway opening mileage of the Second Court of China Railway has exceeded 36,000 kilometers, accounting for 1/4 of the total mileage of the national railway, of which more than 12,000 kilometers of high -speed railways, accounting for 1/3 of the total mileage of the national high -speed rail. The urban rail transit projects participating in the completion have been opened to traffic exceeding 2,900 kilometers, accounting for one -third of the mileage of operating rail transit (subway) in the country. As one of the earliest units in China to conduct highway survey and design, the 7,200 kilometers of highways have been designed.

After 70 years of development, the China Railway Second Hospital has become a leading company and leading enterprise for land transportation surveys in China. Looking back at the road to the Chengdu -Chongqing Railway from the first railway of the New China, we made one hand into Baochengtong, Cheng Kun miracle, and Nankun feat. Since then, the opportunity of the Guangmeishan Railway has begun to start in the market. Fighting in the wave.

With the spring breeze of reform, the Second Courtyard of the China Railway went out of the southwest, continuously developing and growing in the competition, opening the door of the market with self -improvement and hard work, and building the foundation of development with sincerity and wisdom. With the successful construction of the Narong -Chongqing Railway Railway Railway Test Line, the China High -speed Railway has ushered in a good development. In the next ten years, we have undertaken the design of Zhengxi, Guiguang, Chengdu -Chongqing, Xicheng, Chenggui, Chenggui, , Zheng Yu and other high -speed railway lines, as well as the Lalin Railway on the Snowfield Plateau to Lay the Fuxing EMU, the three -generation and second houses wrote a glorious picture of "Tianya Changtong" in the north and south of the motherland.

In 70 years, with the Tanzan Railway as the starting point, the second house began a long journey to overseas. The Tanzan Railway runs through the East African Plateau and span the Rift Valley. In July 1976, it was completed and opened to traffic, becoming the first step in the China Railway Second Hospital to move to overseas.

Since then, the banner of the Second Hospital has floated in the engineering site of the engineering site of Cambodia, Venezuela, Nigeria, Algeria, Ethiopia, Pakistan, Bangladesh, Russia, Laos, and Egypt, and gradually established its own global coordinates. With the efforts of the third -generation and second house people, after three stages of "borrowing ships out of the sea", "boarding ships and going to the sea", "shipbuilding and going to sea", the China Railway Second Hospital has become an excellent representative of Chinese enterprises "going out", and it is also an initiative of the "Belt and Road" initiative. Practitioner and leader. Known as the first order of the Chinese high -speed rail to go abroad, the Russian Maka High -speed Railway, the first city of Eastern Africa's Siyaba Light Rail, and the first cross -border electrified railway Yaji Railway in Africa has created a precedent for the Chinese railway. In the "Belt and Road" and the iconic project of China -Laos, the old railway in the iconic project of China, and the successful opening of the Egyptian Ramadan on the 10th of the city is the latest achievement of the China Railway Second Hospital to actively participate in the construction of the "Belt and Road".

Innovation and leading development

The development of my country's "Fourteenth Five -Year Plan" and longer periods put forward more urgent requirements for scientific and technological innovation. The railway shoulders major responsibilities in building innovative countries, brand building and promoting strong science and technology, and the construction of transportation power. The innovative genes were engraved in the blood of the second house from beginning to end. In 70 years, we have created countless firsts in the history of railway construction and development, and have won more than 30 National Science and Technology Progress Awards, more than 20 national survey and design gold and silver awards, 4 global FIDIC Outstanding Engineering Project Awards, provincial and ministerial science and technology He Chuangyou Award has more than 1,000 items, compiled 168 national and industry standards and 2 international standards, and obtained nearly 2,200 national authorized patents.

Open the historical scroll, from the first railway of the New China railway to the Chengdu -Chongqing Railway to the Chengrui -Chongqing Railway, to the Chengdu -Chongqing high -speed railway, and then to the Chengyu Middle Line high -speed rail. Leading, constantly breaking through the design speed and constantly shortening the space -time distance between Chengqing. Among them, the 17 -kilometer -free rail panel test railway laid by the Chengrui -Chongqing Railway was hailed as the cradle of China's no -rail rail technology, breaking the blockade of foreign technology, and the development of China's high -speed railway has since entered the fast lane. The "Suiyu Line's key technology and application of no orbit railway" won the first prize of national scientific and technological progress.

In the Chinese railway territory, there is such a world -renowned mountain railway. It was built in the 1960s and passed through the "road building forbidden zone" that was asserted by foreign experts. It was known as "the three major miracles of human conquest nature in the 20th century. "one. In 1964, the China Railway Second Hospital made a decision to "go downstairs and leave the hospital" in accordance with the requirements of the superior. We actively innovated and used a large number of new technologies at that time. Twelve technologies reached the international advanced level at that time. The final formation of "built new technology in complex geology and dangerous mountainous areas" won the National Science and Technology Progress Award in 1985. Today, the new Chengcheng Kun -Kun Railway, designed by the new generation of the second -generation house, has shortened 200 kilometers compared to the Lao Shengkun Railway line in length due to the use of advanced survey and design. New glory. In the 1980s, reform and opening up put forward new demands on the construction of transportation infrastructure. The construction of the Southwest Railway opened a new climax, and the state put the construction of the Nankun Railway on the agenda again. Opportunities have come again. The second house is inspiring. After more than half a year of battle, the designer broke the traditional Yishan along the river selection model, and boldly adopted the long tunnel and high -pier large span bridge, which effectively overcome the huge huge Nanyun Line. High differences have created a precedent for the design of single -line railway capabilities in the mountainous areas in my country. Its set of technology generally entered the international advanced ranks at the time, and won the highest national scientific and technological progress award in 2001. In this arduous battle, the Second Hospital has created the spirit of Nanyun, who has created the spirit of "aggressive, improving, striving, dedication, and climbing the peak".

On November 8, 2020, the Sichuan -Tibet Railway (Ya'an to Linzhi section) started the mobilization conference on the three places of Beijing, the Seraka Tunnel, and the Dadu Hete Bridge. At this point, the construction of the Sichuan -Tibet Railway, where the souls of the third -generation and secondary houses, started construction. As early as the early 1950s, the second house began to pour a lot of effort to the Sichuan -Tibet Railway. The footprint of the survey and design team has traveled almost every inch of land. However, the hard work of the first generation and the second house has never stopped. The wheels of history rolled, and the salary of the Sichuan -Tibet Railway had been passed on to the third -generation second house. In order to overcome the key technical bottlenecks, the technical team carried out the scientific research plan of "the Sichuan -Tibet Railway's life cycle" in the level of "Extreme Environment". To reach the international leading level, it fully demonstrates the innovative quality of the second hospital's "careful design and excellence".

Responsible for glory

The bridge is connected to the river, and the orbits are connected to the eight directions. In the seventy years of the establishment of the hospital, the China Railway Second Hospital has always actively responded to the national call, participated in the construction of national transportation infrastructure, and handed over a satisfactory answer to the motherland and the people. In almost every important period of railway construction, the secondary of the China Railway Second Hospital is indispensable.

In the early days of liberation, the Chengdu -Chongqing Railway was built under the conditions of one poor and two white. It was us; the Chengkun Railway, which broke through the road construction restricted area, was us; The people's expectations are our responsibilities, national needs, and our mission.

The spring breeze of reform and opening up has injected a new vitality into the ancient Chinese nation. Since then, the history of China's railway has also opened a new page. In order to develop rich resources in the southwest, the former Ministry of Railways requested that the China Railway Second Court quickly completed the demonization and research of the Nankun Line to build electrification and large capacity design solutions. China Railway Second Hospital eventually formed the longest single -line railway tunnel in my country at that time, the construction of the world's first railway tall bridge at the time in the Qingshui River, and the first dangerous hole in the world in the home. The horizontal plan realizes the breakthrough in the design of the Southwest Shan District Railway.

Electrification leads to the innovation and development of Chinese and old railways

Since the 1990s, my country has begun high -speed railway technology research. However, during the difficult start of China's high -speed rail, the core technologies of high -speed rail were basically monopolized by developed countries such as Germany, France, and Japan. Those who are fighting for the flow, the courageous people wins; At a critical moment, the second house is responsible for mastering the leading technology of the world's high -speed rail, and is determined to change from the "chaser" of the construction of high -speed railways to a "leader."

During the western development period, the former Ministry of Railways decided to build a Suiyu Railway. Among them, the comprehensive test section of Suiyu Wuyi Railway will be used as the first domestic section of the non -rail no -rail test line.定 The foundation of rail technology lays the foundation. The China Railway Second Hospital decisively shouldered this heavy responsibility. In the construction of Suiyu Railway, a key innovation test of the key technology of Wuye -free railings was conducted, and a series of technical problems were solved. It has filled the technology gap in the construction of no orbitals in China, providing technical support for my country's high -speed railway construction. Today, China has built more than 40,000 kilometers of high -speed railway, and the operating mileage is the longest; the speed of 350 kilometers per hour, the fastest operating speed in the world; the full coverage of 31 provinces (autonomous regions, cities) across the country, covering 92%of the country's more than 500,000 population population in the country The cities in the world are the highest in the world, and the magnificent goal of building a powerful country is gradually reaching reality. The road is through, the hundred industry is happy. Driven by the national “Belt and Road” initiative, the China Railway Second Hospital planned a large number of interconnection and interoperability projects in the construction of overseas transportation infrastructure, actively promoting the Chinese railway “going out” and becoming a “open road pioneer” on the Silk Road. In addition, China Railway Second Hospital's advanced planning and dare to be the first. From the perspective of the national development strategy, 4 intercontinental planning such as the "Belt and Road" railway network overall planning was carried out in advance, and 11 multinational plans such as the Pan -Asian railway channel were completed. The study of the "going global" path of China's railway standards helped the "Belt and Road" initiative to take root.

Chao Ping'an is full of strong wind, and sailing is just at the time. Looking back at the past, the three -generation and second house people adhering to the pioneer spirit of the road and continued to target innovation -driven, leading the development of China's railway. Looking forward to the future, we have a deep accumulation of seventy years. We have mastered a group of core technologies that lead the development of the industry. We will definitely write new glory in the history of railway development.
