A few days ago, the "Technical Regulations for Quality Inspection and Evaluation of Highway Concrete Bridge Prestress Construction" compiled by the Fujian Provincial Communications Construction Quality and Safety Supervision Bureau, Fujian Communications Construction Engineering Test and Inspection Co., Ltd., and the China Civil Engineering and Construction Bureau Civil Engineering and Construction Research Institute Co., Ltd. Local standards were issued after approval and implemented on May 8, 2017. Standard number: DB35 / T 1638—2017.
标准 The standard was drafted by our company's chairman Wu Jiazhen and technical director Zhu Jigang, and our company's original shock elastic wave method, equivalent wave velocity method, full length attenuation method, transfer function method and other technologies were incorporated into the local standard. "Technical Regulations for the Quality Inspection and Evaluation of Prestressed Construction of Highway Concrete Bridges" perfects the technical standards for the quality inspection of prestressed systems for concrete bridges, and solves the problem of lack of effective technical regulations for the detection of prestressed beam tension under anchors and grouting compactness of tunnels.
