on August 16, 2011, in the Northern Pearl coastal city Dalian center At the construction site of Yujing ST1 project, a provincial super high-rise new technology application on-site observation meeting was held. A total of about 600 people attended the observation meeting, including Wang Xiangxue, deputy director of Liaoning Provincial Department of housing and urban rural development, Li Haibin, deputy director of Dalian Urban Rural Development Commission, project manager representatives of project quality supervision stations and construction enterprises in all cities of the province, and quality management personnel, project managers, and supervision engineers of construction, construction, and supervision units in Dalian. The meeting was presided over by sunmingfang, head of Liaoning Provincial Construction Project Quality Supervision Station, Dalian center Representatives of the construction and construction enterprises of the Yujing ST1 project introduced their experience. Li Haibin, deputy director of the Dalian Municipal Construction Commission, made a speech. Finally, Wang Xiangxue, deputy director general, made an important speech

the provincial on-site observation meeting on the application of new technologies in super high-rise buildings was held on August 16

the focus of this observation is the application of new technologies in super high-rise buildings. Dalian Center - Yujing ST1 project is the landmark of Dalian, with the highest point of 383.45m. The project adopts 32 new technologies in the "ten new technologies in the construction industry", including concrete crack control technology, ultra-high pumping concrete technology, large-diameter reinforcement straight thread connection technology, hydraulic climbing formwork technology, and automatic calculation technology of quantities. Some of the technology application levels are among the first in China, which is worthy of reference and learning in the whole province, such as the use of profiled steel plate concrete composite floor system, The ribs of profiled steel plate and supporting cushion blocks are used as stirrups for floor reinforcement, which can better control the thickness of floor slab and the thickness of negative bending moment reinforcement protective layer; The integration technology of steel member and straight thread sleeve is adopted to solve the on-site construction problem of the connection joint between steel member and reinforcement; In Northeast China, the wireless remote sensing electronic temperature measurement system is applied to mass concrete maintenance monitoring for the first time; In order to ensure the quality of ultra-high pumped concrete, the largest concrete towing pump with a theoretical pumping height of 835 meters in the north of the Yangtze River is used. At the same time, the project also applied hydraulic pressure for the first time in the northeast and used the same foot to smooth the surface of the test object at a nearly horizontal angle. The climbing formwork system, hgy17 hydraulic distributor, GPS satellite positioning system were used to recheck the measurement control points and the tower crane for construction with the largest lifting capacity in China

Wang Xiangxue, deputy director of Liaoning Provincial Department of housing and urban rural signed long-term cooperation contracts, attended the observation meeting and delivered an important speech

it is understood that in recent years, Dalian has carried out activities such as high-quality main structure engineering evaluation, comprehensive strength ranking of supervision enterprises, reputation list of excellent supervision engineers, and free theoretical lectures for enterprises in combination with actual conditions; Establish a practical operation skill training and assessment base to conduct practical operation skill training and assessment for project quality inspectors, supervision engineers, inspection testers, etc; The self-developed floating stirrup construction technology solves the common problem that the quality of the protective layer of the negative bending reinforcement of the floor cannot meet the requirements of the national construction standard key press and hold work quality acceptance specification; Especially in terms of the exchange platform built for the participating enterprises, the Provincial Department of housing and urban rural development has held a provincial on-site observation meeting in Dalian for two consecutive years since 2005. At present, the overall level of new technology application and project quality in Dalian ranks first in the country. In the past two years, the total number of awards of Liaoning Provincial Construction Engineering Century Cup (provincial high-quality project) Award and construction industry new technology application demonstration project ranks first in the province

representatives from all over the country and the media participating in this observation meeting

the project of this on-site observation was developed by Yujing Xingye (Dalian) Co., Ltd., constructed by China Construction Eighth Engineering Bureau Co., Ltd., and supervised by Beijing Yuanda International Engineering Management Co., Ltd. The project takes the creation of Luban Award as the quality goal, which fully embodies the concepts of energy conservation, environmental protection and low carbon. It is one of the achievements of Dalian in recent years, which pays great attention to the project quality and vigorously promotes the application of new technologies. Through on-site observation, everyone feels that they have benefited a lot and achieved the purpose of typical guidance and common improvement. This activity will further enhance the sense of mission and mission of the provincial engineering quality supervision institutions to do a good job in engineering quality management and the application and promotion of new technologies, constantly innovate and improve the supervision mode, go all out to ensure the quality and safety of the project, constantly improve the use function of residential projects, and ensure that people can have a safe and comfortable living environment. It will promote the continuous improvement of the application of new technologies and the awareness of creating excellence among the majority of construction enterprises in our province, and the continuous enhancement of the construction management ability and market competitiveness of super high-rise buildings, so that technological innovation will become the propeller to improve the quality of projects, and create a section. This material can be used in any kind of domestic flexible PVC products, medium energy, environmental protection, low-carbon high-quality projects, so that more projects become high-quality projects, Promote the overall level of project quality in our province to continue to rise
