The Zhejiang Provincial Department of Transportation hosted the results appraisal meeting of "Research on the Testing and Evaluation System of Grouting Compactness of Prestressed Concrete Beams Based on Elastic Detection Technology" (Project Number: 2013H66) in Hangzhou on October 18, 2015. The appraisal committee reviewed the relevant technical information and unanimously identified that the research results of the project have good social and economic benefits and application value, and the research results generally reached the international advanced level.
So far, this is the fifth scientific and technological achievement that our company has identified as the international advanced level. This project proposes detection methods, judgment standards, and classification standards for the overall analysis of grouting quality of prestressed concrete beam tunnels, and develops a thick-walled structure test method, shock echo resonance migration method. The project research provided a new method and professional equipment for grouting quality testing, and made a real contribution to promoting technological progress in the industry and ensuring project quality.
