Ultrasonic sector scanning method in the application of the accurate determination of the concrete bored pile defect position

摘要：

　　Based on the detection of cast-in-place concrete defects of bored pile as the research object,the scale of the commonly used method for measuring the determination of the defect position,which cant determine the accurate range is very large defect location of the problem,taking the first measurement method,planing initially determined by fan scanning method to determine the accurate out concrete piles defect position method,and digging pile defect position after the actual situation comparison of verifying test,test results are accurate effect and good.
