Chenguang Li's deeds

65438-0988, Chenguang Li graduated from the Department of Civil Engineering of Tianjin University, and in the 1980s, as the first batch of foreign graduate students, he joined the Building Structure Research Office of the Institute of Construction Research. Soon after joining the work, I caught up with the "Research on Construction Technology and Application of Prestressed Concrete Structure of CCTV Building". For a newly graduated student, it is a rare opportunity and a great test to participate in the construction of the first TV tower in China. At that time, little was known about the prestressed construction above 100 meters in China, and no tower building was ever built. However, the vertical prestressing tendon of CCTV building reaches 270 meters. How to smoothly penetrate a large number of prestressed tendons into the reserved channel has become a major problem in construction. While everyone was racking their brains, Chenguang Li came up with a practical and effective "indigenous method": after tying seven prestressed tendons in a hole into a bundle, take out one of them and tie it to the steel wire of the hoist, and then hoist it into the hole as a whole. After testing, this method simplifies the complexity, greatly improves the efficiency and reduces the construction difficulty. This is the first time that Chenguang Li showed his potential in solving the problem of prestressed construction.

199 1 year, Chenguang Li went to Hongkong Lin Tongyan Consulting and Design Company as an intern, engaged in architectural and bridge engineering design. When I was doing bridge engineering in Taiwan Province Province, I was exposed to "external prestressing". (External prestress, simply put, means putting the prestress originally placed in reinforced concrete outside, which can greatly reduce the self-weight of the structure. It is suitable for high-rise and long-span buildings and is the best choice for steel structure engineering. ) Based on the international advanced technology trends that I have learned through reading a large number of foreign related works, Chenguang Li is keenly aware that "external prestressing" technology will have great prospects in the future construction market and reinforcement and reconstruction market, so he decided to conduct project research on this technology. Although the domestic market was immature at that time, most of the peers didn't know much about "external prestressing" and even doubted its feasibility, Chenguang Li insisted on this road. From 65438 to 0995, as the first person in the construction industry, he was selected as the "Beijing Science and Technology Rising Star" program, and he chose the topic of "Research and Application of Efficient External Prestressed Structure Anchorage Technology" for research, becoming the first person in China and Beijing to study "External Prestressing". Amid resistance and doubts, Chenguang Li overcame the difficulty of not having a pilot project, accumulated and expanded a little bit, and took pains to do experiments. Finally, he successfully completed the research and passed the appraisal of the Municipal Science and Technology Commission. Later, the development of technology and market proved that his choice was forward-looking Up to now, external prestressing technology is widely used in many large-scale projects at home and abroad, and well-known domestic prestressing manufacturers also regard external prestressing system products as a new economic growth point. Chenguang Li presided over the research of "Efficient External Prestressed Structure Anchorage Technology", which has been successfully applied to more than 30 projects, and the research results have been adopted by two national prestressed technical regulations. From 65438 to 0998, with excellent professional skills and a series of scientific research achievements, Chenguang Li became the youngest professor-level senior engineer in the history of the Institute and was promoted to chief engineer of the Institute. After 10 years of tempering, Chenguang Li has also become more mature through diligence. After Chenguang Li became the chief engineer, his exploration on the road of scientific research did not stop. On the contrary, because of his greater mission and more responsibilities, he kept learning and gradually grew into a compound scientific research manager. The growth and development of Chenguang Li is in step with the reform and development of scientific research institutes. In the 1980s and 1990s, scientific research institutions were pushed to the market by the wave of reform, and they were responsible for their own profits and losses. Many technicians have to do research and expand the market, and some ideas of quick success and instant benefit have emerged. However, Chenguang Li insisted on his belief: "I don't approve of not developing technology and not creating profits, but I will never give up the research on new technologies, because it is extremely short-sighted. My choice is to adhere to long-term research on new technologies while completing development and engineering tasks. " Supported by the policy of "keeping one end stable and letting one end go" of the Municipal Science and Technology Commission, the Institute of Architectural Research established the Beijing Building Technology Research Center on 1997, with Chenguang Li as the deputy director. Later, he and his colleagues, including three newly recruited doctoral students, started with the topic. He is mainly responsible for contract negotiation, and technicians can make plans and designs with peace of mind. This model continued until Chenguang Li became the chief engineer of Architectural Research Institute. The tacit cooperation and clear professional division of labor make them not only make outstanding achievements in scientific research, but also do well in the market. On the subject of "Research on Durability Evaluation Technology of Reinforced Concrete Engineering", they established a set of new quantitative and qualitative methods for structural durability evaluation and prediction, and combined with modern detection methods, they have been effectively applied in practical projects. Extending from this topic, they actively expand the steel bar market. In 2005, they successively undertook two large-scale projects, namely, the overall reinforcement and renovation of the Innovation Center in Langfang Development Zone and the office building of the former Construction Bureau, with a total area of 49,000 square meters and a total contract value of nearly120,000, which reached the highest value in the first half of the year since the establishment of the research center. In addition, the research center has undertaken major projects of prestressed steel structure and special structure engineering. In order to keep a keen sense of technology and market, Chenguang Li has been studying and taking advantage of various opportunities to further study and improve. Since 2000, I have participated in all kinds of management training for nearly 400 hours. When he met the opportunity of further study in China, he used all the conditions to collect technical information: when he saw the roadside parking lot, his first reaction was to strengthen it; Seeing that the university building was being reinforced and rested, he took out his camera and took pictures; When he visited the traffic command center, he spoke fluent English and guided the staff to exchange professional problems ... In Chenguang Li's own words, his eyes lit up when he saw something new. When others return home with souvenirs and local products, they bring back a lot of valuable scientific and technological materials. With the increasingly fierce market competition, as a scientific research institute, how to continue to give full play to its knowledge and technical advantages is a question that Chenguang Li has been thinking about: "Prestressed comprehensive technology, scaffolding technology and reinforcement and transformation technology-the Institute of Construction Research has made outstanding achievements in the market transformation of these three topics, which not only created good profits, but also won a good market reputation and word of mouth. This is mainly due to a set of intellectual achievements including achievements, patents, construction methods and specifications. In the research of these technologies-each technology must be accumulated by many achievements, and it is impossible to occupy the market in a way close to a single achievement. "
