[0002] At present, pile foundation is a common foundation structure. The quality of pile foundation hole formation directly affects the safety and durability of the structure. In order to ensure that the quality of pile foundation construction meets the specifications and design requirements, the commonly used quality control methods are process detection and timely correction. During the construction process, the frequency of detection of hole diameter, hole depth and verticality is increased and assisted by correction methods to improve the quality of hole formation and reduce or avoid rework losses during the process. At present, the commonly used pile foundation hole formation detection methods include the cage method, the measuring rope or the hole formation detector, but these methods have the following disadvantages: First, the measuring rope method requires the establishment of an auxiliary construction platform and the use of cross control piles to measure verticality and hole diameter, which is complicated to operate and has high safety risks; second, the cage method requires the assistance of lifting equipment, and the detection time is long. The increase in the detection frequency not only increases the construction efficiency but also increases the cost; third, the hole formation detector has too large a one-time investment, which is suitable for underwater pile foundation detection, and the data analysis time after detection is long, and it is generally used for final hole detection.
