    On October 19, 2017, the 2017 Annual Conference of the Chinese Hydraulic Engineering Society was held in Xi'an. The conference held the awarding ceremony of the 2017 Dayu Hydraulic Technology Award. Our company's hydraulic structural concrete quality detection and evaluation technology based on shock elastic waves won the second prize of Dayu Water Science and Technology Award, and the company's chairman Professor Wu Jiazheng won the second prize of the individual.

     

     

    Shock elastic wave-based concrete quality inspection and evaluation techniques for hydraulic structures, including elastic wave CT and non-destructive testing methods of transient surface waves. The shock elastic wave is used as the test medium, which is excited by the vibrating hammer. The energy is large and concentrated, the test depth is significantly increased, the site operation is simple, the working surface is low, and it has obvious advantages compared with the traditional ultrasonic method. The methods of receiving, collecting, filtering, and analyzing make the test results less affected by the stray waves in the medium, ensure the detection accuracy, and greatly shorten the time for detection, data acquisition, analysis, and formation of the results; the elastic wave speed obtained by the detection (P wave and R wave) can establish an effective physical correlation with the mechanical properties (dynamic elastic modulus and strength) of concrete.
     
    In China, the impact elastic wave technology is mostly used in the detection of concrete structure defects in the construction industry. Our company's project technology has overcome many key technical problems in the application of hydraulic concrete defect detection, making it applicable to hydraulic concrete structures. The project technology includes a number of independent intellectual property rights, integrates a number of high-tech testing instruments such as prestressed systems, concrete materials and structural testing, and is used in many industry benchmarking projects such as the Jiaozhou Bay Bridge, the Dazhi River Bridge between the two ports, and has significant economic and social benefits.
     
    The Dayu Water Science and Technology Award is the highest award for high-quality engineering in the national water conservancy engineering industry. It rewards scientific and technological achievements that have been proven to have significant economic, social, and ecological benefits.
