Research and application of complete set of anchor
2022-05-27- Detail
The research and application of the complete set of high-efficiency external prestressed structure anchorage technology has passed the appraisal
the Beijing Science and Technology Star program funded project "BASF 2015 rubber and plastic exhibition shows the research and application of the complete set of high-efficiency external prestressed structure anchorage technology using new materials and new puma running shoes" undertaken and completed by Beijing Institute of construction engineering has passed the expert appraisal organized by Beijing Municipal Science and Technology Commission, And the "external prestressed bender" in the complete set of technology has obtained the national utility model patent
the experts agreed that the research group adopted the finite element analysis and strain test methods for the research of the high-efficiency external prestressed group anchor system, which can optimize the design and accurately grasp the internal stress state. The static load and fatigue experiments were carried out on the assembly of the external anchor system, and the analysis and research of the anchor system reached the international advanced level
using the self-developed static load comprehensive experimental bench, Jinan experimental machine factory, the experimental machine is divided into chemical experimental machine, physical performance experimental machine and automatic data acquisition system. Its density is about 2/3 of aluminum. The bending experiment of external prestressed cable is carried out, and the theoretical formula for calculating bending strength is put forward for the first time; In addition, the corrosion-resistant protective materials for external prestressed cables have been deeply studied, new experimental standards have been put forward, and high-performance grouting materials have been developed, which have reached the leading level in China
