Xinhuanet Beijing, April 29th (Zhengxian Xiaomei) On the 29th, 430 advanced collectives won the "National May 1st Labor Certificate" and 1,095 advanced individuals won the "National May 1st Labor Medal" at the International Labor Day Conference held by the All-China Federation of Trade Unions in Beijing. Among the winners of the "National May 1st Labor Medal", there is an underground engineering expert from the fiery Beijing Olympic construction site ―― Huang Changfu, deputy chief engineer of China Railway 16th Bureau Group and commander of Beijing Engineering Headquarters, manager and senior engineer of the underground diameter line project department of Beijing Railway Hub from Beijing Station to Beijing West Railway Station. This model of the times who has been struggling for years has silently written a touching heroic song with his own practical actions.
Joining the subway construction, he and his family regard the construction site as their home.
In the evening, Huang Changfu, who looked tired, just walked out of the underground diameter line tunnel in Chongwenmen, Beijing, when the mobile phone on his waist rang, there came the voice of his son in tears: "Dad, the children have all gone, and you forgot to pick me up again."
"Oh, my son, I’m so sorry. Dad will pick you up right away!"
Huang Changfu’s wife works in Tongzhou District, Beijing, and his 4-year-old son is in full-time nursery school in Mudanyuan Kindergarten in Haidian District, Beijing. He himself is busy at Chongwenmen construction site all day. This kind of life, dubbed by the workers as "cross-strait and three places", makes it possible for their family of three to meet only on weekends. Once, the child caught a cold and had a fever. The kindergarten teacher let the parents go, which coincided with his wife’s business trip. Huang Changfu was directing the installation of the shield machine at Shuangjing, so he had to let the driver go to see how the child was. The teacher who didn’t know the truth complained: "The couple are too careless about the children."
Hearing the child’s blame, Huang Changfu suddenly thought that today is the weekend and it is high time to pick up the child. It’s no wonder that due to the tight construction period, Huang Changfu and others have never had the concept of Sunday. For subway builders, the most difficult question to answer is probably "What day is it today?" There is no cell phone signal in the tunnel, and the child has been on the phone for a long time. Huang Changfu can’t help feeling deeply guilty.
"Dad, are we going home to the construction site or Tongzhou?"
"Son, dad is busy, let’s go back to the home of the construction site first!"
From the day he joined the subway construction, Huang Changfu regarded the construction site as his home. Not only he, but also his wife and children regard the construction site as their home.
Huang Changfu, 36, was born in Xinxian County, Henan Province. Xinxian county has many heroes since ancient times. This is the center of the revolutionary base area in Hubei, Henan and Anhui. On this red land, there have been 43 distinguished generals such as Xu Shiyou, Li Desheng and Zheng Weishan. All these have a subtle influence on Huang Changfu’s growth.
In 1998, Huang Changfu, who had just obtained a master’s degree from University of Science and Technology Beijing, came to the construction site of Beijing Subway Fuba Line of China Railway 16th Bureau Group. A person in charge said to him, "subway construction is a profession with complex technology, hard environment and high safety risks. You should think it over."
Huang Changfu, who is full of ambition and determined to make a career in the field of subway engineering, replied without hesitation: "I have thought about these questions since the day I set foot in the university gate."
Since then, there has been a young figure in the subway construction site under Chang ‘an Street.
In the early morning, when people walked into the spacious and bright office building in bright sunshine, Huang Changfu and his colleagues walked into the dark and humid tunnel in long rain boots; In the evening, when they were covered in muddy water, they dragged their tired feet down the tunnel face, and people in fashionable clothes had walked comfortably on the bustling Chang ‘an street … Huang Changfu began to understand the true meaning of the word "hardship". Just out of the institutions of higher learning, he inevitably felt a huge psychological gap. He secretly said to himself, "Huang Changfu, Huang Changfu, you must hold on!" " He grades his will and perseverance every day. Climbing the arch and erecting the grille, he fought bravely for the first place. When encountering construction problems, he carefully studied the construction drawings, asked experienced old experts for advice, and seriously thought about solutions. In a few months, he has basically mastered some procedures and methods of subway construction. Looking at the problems solved one by one, the tunnel moved forward one meter at a time, and his heart involuntarily felt a sense of accomplishment.
In May 1999, Huang Changfu was appointed as the deputy chief engineer of the project department of Jiangnan Xincun Station of Guangzhou Metro Line 2 of China Railway 16th Bureau Group, mainly responsible for the construction of the underground excavation section of the north and south station halls. The upper part of this stratum is soft soil layer, which needs to be supported in time after excavation, and the lower part is rock layer, which needs blasting operation. He consulted relevant information, carefully studied the characteristics of rock strata and the foundation of buildings, and put forward the micro-vibration controlled blasting technology, which solved the technical problem of the influence of underground excavation in soft and hard mixed strata and blasting on the foundation of surrounding buildings. Subsequently, Huang Changfu was transferred to Xiaojiang section to be responsible for tunnel construction. This section is the turn-back line of Guangzhou Metro Line 2 and Line 5, including 21 sections and 41 section change points, and almost all the construction methods in the underground excavation method are involved. The biggest difficulty of the project is that it passes through 11 high-rise buildings and needs pile foundation underpinning. Huang Changfu consulted a large number of materials and collected first-hand data in detail. By using engineering analysis and numerical simulation calculation, he analyzed the influence of tunnel excavation on the ground and buildings, determined the number and scope of pile foundation underpinning, solved the pile-beam connection, graded loading and synchronous jacking technology of pile foundation underpinning, and put forward the concept of "load dispersion method", which avoided pile interception and accelerated the construction progress.
With the spirit of dedication, striving for perfection and work style, Huang Changfu has grown into an excellent subway construction technology leader and project management backbone in just a few years. Since October, 2002, Huang Changfu has been successively appointed as the deputy manager and chief engineer of the shield engineering project department of Shenzhen Metro Phase I of China Railway Sixteen Group, the project manager and secretary of the Party Working Committee of Beijing Metro Line 10, and the project manager of underground diameter line from Beijing Railway Station to Beijing West Railway Station. Every project managed by Huang Changfu is almost the highlight of technological innovation, project management and civilized construction.
The son once puzzled his mother: "People all work in beautiful tall buildings, why does dad always drill into that dark hole?"
The mother jokingly said to her son, "Dad, it belongs to pangolin. If you don’t let him dig a hole in the ground, he will suppress something wrong."
