摘要根据冲击回波法检测基本原理,利用其对预制箱梁预应力管道压浆密实情况进行了无损检测,并在咸旬高速公路某标段引桥预制梁场进行了实际检测,经验证,冲击回波法可有效的对预应力孔道进行压浆密实度检测。 Based on basic principle of detection using impact-echo method, impact-echo method has been used for non-destructive detection of grouting compactness in pre-stressed ducts inside prefabricated box girder. The author conduct a tested in a unit producing yard for the approach of one bridge in Xian-Xun highway, test results shows that the impact-echo method can effective inspection of grouting quality in strands of pre-stressed ducts.
