◆Beijing Municipal Engineering Group attaches great importance to scientific and technological research and development, conscientiously implements the idea of ??"science and technology is the primary productive force", consciously increases investment in scientific and technological development, and founded the Beijing Municipal Engineering Research Institute in 1959 The Municipal Engineering Research Institute has developed into a comprehensive scientific and technological unit in the capital. It currently has 216 employees, including 10 professors and senior engineers, 38 senior engineers, and 54 engineers. Intermediate and senior technical personnel account for 48% of the total staff.
◆In terms of scientific research, in urban roads, bridges, structures, underground engineering, water supply and drainage engineering, concrete materials, engineering inspection, pipeline assembly, high-performance special concrete technology, concrete non-destructive testing technology, and efficient small-scale construction In-depth research has been carried out in professional fields such as machinery and equipment, forming certain technical advantages and making certain contributions to the municipal infrastructure construction of Beijing. For example, the research results of the "Shallow Burial and Undercover Excavation Construction Technology Research" project have enabled the "Shallow Burial and Undercover Excavation Method" to be rapidly promoted and applied to the subway-Fu8 Line Project, a large number of pedestrian underground passages in the city, and a large number of municipal public pipelines and tunnels. and other projects; "Intelligent Concrete Ultrasonic Inspection and Analysis" has not only played a great role in the quality inspection of large overpasses and important engineering structures in Beijing, but has also been applied to large-scale national key projects such as the Three Gorges Dam Project on the Yangtze River and the Jiangyin Bridge on the Yangtze River. In the project; the research results of "modified asphalt and SMA application technology" are applied in key parts of key projects such as Ping'an Street, East Fourth Ring Road and Capital Airport runway in Beijing; in terms of drainage pipeline construction technology and new concrete material research, every year There are new achievements used in Beijing's urban construction: CP-4 road leveling instrument, dual-amplitude oscillating rammer, etc. have played an important role in key projects in the capital and the country. It has won more than 20 major achievement awards such as national, ministerial and municipal scientific research progress awards and invention achievements.
◆In accordance with the spirit of documents such as the "Implementation Opinions on Further Deepening the Reform of the Science and Technology System of Municipal Scientific Research Institutes" by the central government and Beijing Municipality and the policy of "holding one end firmly and liberalizing the other", structural adjustments were made, and personnel The diversion has transformed most of the scientific and technological forces into design, supervision, engineering inspection and technology industry teams. At the same time, a team accounting for about 20% of the total number of scientific and technological personnel has been retained to continue to undertake public welfare scientific research projects. And established corporate entities such as design institutes, supervision companies, engineering inspection technology companies, pipeline companies, and out-of-town branches.
◆On May 26, 2005, the 2004 Beijing Science and Technology Progress Award was announced, including "Research on Key Technologies for Shield Tunnel Construction in Waterless Sand and Pebble Strata" developed by the Municipal Construction Group and Beijing Jiaotong University. 34 This achievement won the first prize. ***291 projects won awards, including 34 first prizes, 140 second prizes and 117 third prizes. The “Development of Mud-added Earth Pressure Balance Shield Machine and its Supporting Technology Research” by five units including the Beijing Municipal Engineering Research Institute won the second prize of the Municipal Science and Technology Progress Award; the “Asphalt Concrete Low Noise” developed by six units including the Municipal Corporation The "Pavement Technology Research and Demonstration Project" and the "Experimental Research on the Fatigue Performance of Steel-Concrete Composite Beams", a joint project between the Municipal Engineering Research Institute and Tsinghua University, won the third prize for Municipal Science and Technology.
