One inch of Danxin can be replied to the country

——Reamed the founder of the Southwest Railway Construction Technology, Liu Jianxi, a famous railway engineering expert

Wei Pan

In the long river, some figures are always marked in history. Liu Jianxi, a well -known railway engineering engineering, a well -known railway engineering expert, and a special award winner of the National Science and Technology Progress Award.

Liu Jianxi

Liu Jianxi, the appointment of the State Council, the outstanding talents of the railway construction of Premier Zhou Enlai personally issued a letter of appointment, the founder of the Southwest Railway Construction Technology. Representatives of the National People's Congress, representatives of Guizhou Province, Sichuan Province and Chengdu People's Congress and members of the CPPCC, and director of the China Railway Association. In June 2021, it was rated as "Pioneer Pioneer" by China China Railway Co., Ltd.'s party committee.

In February 1963, Prime Minister Zhou Enlai signed the appointment of Liu Jianxi

In 1931, after graduating from Cornell University, Liu Jianxi declined the Poa Railway Company to retain and resolutely returned to the country to participate in the construction of the motherland. He has been interviewed by Chairman Mao Zedong and Premier Zhou Enlai, and has made important contributions to the construction of New China. In the construction of Chengyu, Baocheng, Sichuan Guizhou, Gui Kun and other Southwest Railway Conferences, Liu Jianxi took on comprehensive technical leadership.

On June 15, 1950, the Southwest Railway Engineering Bureau (predecessor of the China Railway 2 Bureau) 130,000 road construction army was built into the Chengyu Railway

Inspirational reporting national diligence study

On September 2, 1906, Liu Jianxi was born in the old house of Beitai Oilfield, Liling County, Hunan Province. His father Liu Fukou studied in Japan in his early years. I deeply feel that the powers are looking at, and the country is weak. Liu Jianxi has developed a good habit of hard work, diligent and learning, and has been well -assigned family education since childhood. He has often taught himself to strengthen himself and become a person who is beneficial to society.

In 1920, Liu Jianxi was admitted to Changsha Changjun Middle School. With two years of course, all courses for four years graduated in 1922.

In the same year, Beijing Tsinghua Academy recruited three middle school students in Hunan. Liu Jianxi, who was only 16 years old, stood out among many candidates and was admitted with the second place. At that time, many of the students in Tsinghua Academy were children with noble officials. In contrast, Liu Jianxi was a poor student, but his academic performance was excellent.

In 1928, after graduating from the Tsinghua Academy, Liu Jianxi was selected and sent to the University of the United States to study with Gengzi compensation at the time.

The University of Cornell University is extremely large and there are many departments. From the poverty -stricken and backward China to the United States of capitalism at that time, the traffic in all directions made him very envious. From the development of the United States, let him see that a country wants to develop industry and must develop railway transportation first. Specializing in structural science and railway science, determined to study railways for the motherland after success.

Liu Jianxi studied in Cornell University

In August 1931, Liu Jianxi graduated from the Research Institute of Cornell University, obtained a master's degree, and was recommended by American engineering experts. He was employed as an internship engineer in the US Boa Railway Company. Liu Jianxi's talent was praised by the chief engineer and company manager of the bridge, adding glory to the descendants of Yan and Huang.

Resolutely return to China to repair the railway

The excellent working conditions and good living benefits of Abo cannot tie a patriotic heart. In the spring of 1933, Liu Jianxi rejected Boa Company's retention and resolutely returned to China. At that time, Tsinghua University and Hunan University would hire him as a professor. "". These did not shake his original intention, but his father was old, and he felt guilty as a son of man, but in the end he still walked into his career he loved without hesitation, and walked into a career for the motherland and dedicated to more people.

Liu Jianxi

Regardless of the initial bridge design, responsible for a branch segment, or a longer -distance survey design, Liu Jianxi always completed the tasks of various work tasks by himself, night, and meticulously. Due to his outstanding performance in Qiahan, stations, and tunnel design and review work, Liu Jianxi was awarded by the Ministry of Communications at that time. In the 16 years of the old China, he participated in the survey and construction project of Pinghan, Guangdong, Hanhan, Beijing, Jiangxi, Xianggui, Tiancheng, Qiangui, Xianggui Guizhou and other railways, as well as highways such as Sichuan, Sichuan, Yunnan, and Guangdong. Gang Engineering Department, Deputy Engineering Department, Director of Design Office, Chief Duan Duan, Survey Captain, Chief Engineer of the Bureau, Director of Materials, Engineering Director, and Deputy Director of the Engineering Bureau, and once served as professors and professors and professors of Chongqing Central University, Guizhou University, President of Guiyang Branch of the Chinese Civil Engineering Society. However, due to the corruption of the National Government, although Liu Jianxi did not work hard, he ran around and participated in many railway construction, but he could not show his own talents and ambitions. In his own words It's just tired ", and he is increasingly losing confidence in the Kuomintang.

Liu Jianxi is at work

On the eve of the founding of the People's Republic of China, Liu Jianxi was the deputy director and director of the construction of the Dudu Section of the Xiangui and Guizhou Railway Engineering Bureau. At that time, thousands of employees lived in the road section, and Liu Jianxi ignored his personal safety. He crossed the rigorous Sichuan -Guizhou Highway who reactionary military and police at the time and rushed to Chongqing. The number of direct relatives provided by employees is an average distribution to help everyone cross the difficulties. The employees and the masses are extremely grateful. Liu Jianxi is at work

The liberation army is approaching Guiyang, and Liu Jianxi united them to actively prepare for liberation, announced that the staff of the entire office freezes, and do not flow, and organize various technical and personnel files, property, supplies, equipment, etc. He did not provide transportation for the Kuomintang to escape the army, and he also disassembled the main components of all cars. After the road building machinery and equipment reserved, after the founding of the People's Republic of China, the new China has played an important role in the repair of Wujiang Bridge and Hunan, Guizhou, Gui Kun, Sichuan and Guizhou Highway. Become a backbone force.

Disclosure of the Southwest Exhibition

The establishment of New China has opened up the broad world for Liu Jianxi's exhibition. He successively served as a member of the Guizhou Relief Committee and the leader of the engineering team, deputy director of the Guiyang Railway Engineering Office, chief engineer of the Guiyang Railway Bureau, Deputy Director of the Technology Division of the Second Railway Engineering Bureau, Deputy Chief Engineer, Chief Engineer, Technology The second director of the committee and other positions used all his energy and talent in the construction of the Southwest Railway.

During the construction of the Chengqing -Chongqing Railway, he proposed to change several factories west of Ziyang to pouring on the spot to speed up the progress of the project; in the construction of the Baocheng Railway Bridge, in order to solve the technical problem of the construction of bridge -based construction on the descending sand, It is proposed to adopt the method of using steel plate pile coffin and outer funds to injected cement and mortar to subdue quicksand; in the battle for the Southwest Railway Construction Conference of Sichuan Guizhou, Guikun, and Chengkun Railway, Liu Jianxi, who has been in Huajia, is still full of enthusiasm. Frequently in -depth construction, living in the sheds, drilling tunnels, wading mountains and wading, not avoiding danger, wherever there is a traffic jam, he can solve it where he goes. In order to rectify the large -scale soft soil base in Guikun Line, the battle team led by Liu Jianxi, more than 40 days and nights in the construction site, repeated trials, summarized the "Shenzhen built bridge, shallow building gear, two meters of stones to fill rock filling stones in two meters. , The soft soil rectification experience of the flat sanding pile "finally cure the dam abuse of the dam to ensure that it is opened on time. In the northern section of the Chengkun Railway with a difficult engineering, it is difficult to ensure the construction period according to the original bridge plan. After Liu Jianxi's inspection and research, it was decided to use the steel beam pre -frame, box -shaped steel concrete beam pre -string, general reinforced concrete beam in the construction method, and the general steel concrete beam beam The "three pre -early" measures such as pre -irrigation have greatly shortened the construction time of the bridge.

In the early 1960s, the country was in a period of economic difficulties and the cement was scarce. Liu Jianxi proposed to use prefabricated pieces of stone blocks to save cement and spend difficulties. After this experience was introduced at the National People's Congress, it was valued by national leaders. Premier Zhou Enlai also met with Liu Jianxi for this reason.

Pass the book to pass the descendants

A person's life is limited, but social development is not exhausted. He must work hard during his lifetime, and leave knowledge to later people. This is Liu Jianxi's philosophy of life.

Liu Jianxi attaches great importance to the construction of technical management and technical teams. He organized the formulation of the "Regulations on the Technical Work of Southwest Railway", "Technical Responsibility System" and "Interim Rules for Construction Management", and founded the "Southwest Technical Communication" magazine new technology. He also organized the technical information summary of the southwestern railway trunk line and the experience of the Sichuan -Guizhou Line Liangfeng Tunnel.

He is diligent in study, and the book "Introduction to Railway Fixed Line" is based on China's railway data. It is explained from the combination of theory and practice. Each principle has practical examples. In actual construction, in 1948, it was selected by Guizhou University as a textbook. After the founding of New China, Sun Yat -sen University and Shanghai Jiaotong University also used some chapters as textbooks.

During the "Cultural Revolution", Liu Jianxi was devastated, and he was seriously ill in his later years. In the case of cirrhosis, inverted protein, and swollen legs, he still translated the works such as "Internal Dynamics" and "Rock Mechanics" and other works. The thesis "Application of Railway Section in Railway Design". In November 1979, Liu Jianxi, who was sick, was also supported by his body. He took a paper to Beijing to attend the first congress of the China Railway Society to discuss how to solve the problems of railways in design, construction, and operation. Railway transportation goes to modernization as soon as possible to contribute to the heat. In this way, he expresses the most sincere love for the motherland as ever, and the most firm adherence to the railway industry. Until the last scene of life, he always practiced the vows of Tsinghua Academy's "Tsinghua students to strive to work for 50 years for human health". In 1985, the subject developed by Liu Jianxi's "Building into a New Kun -Railway New Technology in Complex Geology and Dangerous Mountains" was awarded as a special prize of national science and technology progress.

As a role of example, do a model

There is no regret to enter Huaxia in this life, and one inch of Danxin is only returning to the country. Liu Jianxi is a firm communist supporter. He really loves the motherland. He has superb professional knowledge, dedicated work attitude, open -minded broad mind and unyielding strong will. Build a communist society to play light and heat. When he was a teenager, he set up his will to report to the country, studied hard, and studied hard. In order to learn English, in the ice and snow, he got up at 5 am and walked to the teacher's family to learn more than ten miles, because he knew that science and knowledge were the most favorable weapon to change the current status of the old China at that time.

During his youth, he was not seduced by a strong treatment and comfortable environment. After learning, he resolutely chose to abandon the beauty and return to the country, and built the dream of the Chinese railway on the land of the motherland with his own hands. Open roads and build road construction. He took Li Siguang as an example to step on all the difficulties and dangers, and wrote the "practical thesis" that he learned on his own country with his hot love and fiery feelings on the land of the motherland!

During the middle age, he had accumulated rich experience on the front line of road building, and perfectly combined theory and practice. Through a project, a tree is a monument, and it became a good story. The construction of a number of railway arteries has made an indelible contribution to the nationwide and the world that has been connected to the southwestern area since ancient times, and laid the Qianqiu foundation for the southwest development.

He is not only a talented, gentle and considerate good husband in his wife's eyes. He is serious and responsible for foreign work, meticulous and rigorous, and has never "leadership" and "traditional thoughts" in the internal. "good". He is also a good father who is selflessly dedicated to his children's eyes. He held a high salary of 303 yuan per month with a high salary of 303 yuan per month for international students (senior intellectuals, professors -level senior engineers) at the time. ; He taught his children as long as a qualified worker is noble and admirable.

Liu Jianxi, a New China railway builder we should always remember!
