Abstract：Withthe increasing requirements forthequalityand eficiencyofroadand bridge engineering，pile foundation hole-forming detection has becomea keyfactorin ensuring project safety.Taking the Dezhou Road West Extension and Dongjin Yelow River Bridge Project as the research background，aiming at the problems of deformation and large detection deviation of traditional reinforcement cage holedetectors，a modern advanced ultrasonic holeforming detector was introduced.Based onthe principleof ultrasonic reflection，thisdevice can accurately detect indicators such as hole diameter and hole depth，with significant advantages.The application results show that it greatlyshortens the detection period，reduces costs，avoids sediment polution，provides reliable guarantee for pile foundation quality，and achieves good benefits.
