This system is mainly used for hole formation quality inspection of drilling piles. The complete set of equipment includes measurement probes for well diameter, sediment, verticality, and main components such as winches, cables, wellhead pulleys. The host uses a laptop and a portable printer. During detection, various detection data and curves can be displayed in real time, and these data can be stored and printed out. It can easily prepare inspection quick reports and hole-forming quality inspection reports, and the storage and processing of data are convenient and fast, which can greatly improve work efficiency and quality.
