    From November 6th to 7th, the 2nd China Highway Society Standardization Annual Meeting was held in Nanjing, Jiangsu. Mr. Weng Mengyong, former director of the China Highway Society (formerly Deputy Minister of Communications), Hong Xiaofeng, deputy director of the Department of Science and Technology of the Ministry of Transport, Ling Yaochu, chief engineer of the Jiangsu Provincial Department of Transportation, Yuan Xiaopeng, director of the Group and Enterprise Standardization Division of the Standard Innovation Management Division of the State Administration of Market Supervision The former Secretary-General of the World Road Association (PIARC) and Lord Jean-François CORTÉ, Honorary Chief Engineer of the French Ministry of Transport attended the meeting. More than 400 experts, scholars and engineering and technical personnel from the industry attended the meeting.

 

 

 

Our company, as a scientific and technological enterprise specializing in R & D and production of non-destructive testing equipment and Internet of Things monitoring, was invited to participate in this conference. At the meeting, the company participated in the "Technical Guide for Highway Bridge Prestressed Tunnel Grouting Compactness Shock Elastic Wave Detection Technology" group. The standard was approved and released and will be implemented on October 9, 2019. The standard number is T / CHTS 10012-2019.

 

 

This standard was drafted by our company's Chairman Wu Jiazheng and technical engineer Yang Sen, etc., and our original shock wave method, equivalent wave velocity method, resonance migration method and other technologies were incorporated into the standard. "Technical Guide for Shock Elastic Wave Detection of Pre-stressed Pore Density of Highway Bridges" regulates the method for detecting the grout compactness of pre-stressed holes of bridges using shock elastic waves, providing a reliable basis for the evaluation of test results.
