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 can't 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. In the concrete bored piles detection, the level measurement method that ultrasonic testing is generally used for measuring the location range of the defects inspects too large range, which brings the inspection people can't determine the accurate defect position, affects the normal construction. Based on the engineering practice of using level measuring method and fan scanning technique combining detection methods to solve the determination on the accurate location of the defects in concrete bored piles.
