Main applicatio 

• Hole diameter, perpendicularity, collapse expansion and shrinkage position and dip azimuth detection of holed pile;
• Trench width, perpendicularity, collapse expansion and shrinkage position and dip azimuth detection of underground diaphragm wall;
• Guide the site construction according to the measured results, optimize the construction process, improve the construction quality and efficiency;
• Hole expanding effect detection of disk pile and expanded hole pile;
• Sediment thickness detection.

Advantage  

• Teal-time detection, synchronous printing, true and reliable results;
• Clear image of hole and trench walls and accurate detection result;
• 2D-3D display of hole and trench walls, flexible switching, intuitive image;
• Seamless switching between dry hole testing and mud hole testing, strong adaptability;
• Achieve remote data sharing and real-time synchronization by working with cloud platform.

Technical feature 

• The power supply system achieves both AC and DC power supply, with strong adaptability: the whole system can supply power by either AC 220V power supply or self-supplied DC power supply, which eliminates external power supply, being convenient and easy to use;
• The whole system is digitalized: the whole test process and the probe lifting system can be automatically controlled by software, and the measured data and test results can be digitally displayed, stored and printed out;
• On-site direct printout: the control box with printing function is used to realize printout while measuring, being intuitive and real;
• The host system is stable and reliable: the host system is a low-power embedded system, and the software system is based on Linux, and the system is stable and reliable;
• The probe lifting system has good stability: the probes are suspended independently by two load-bearing steel wire ropes and work synchronously to ensure that the probes run smoothly, and do not rotate and interfere with each other. The upper stopper ensures that the steel wire ropes are lifted to the top without breaking, and the lower stopper ensures that the probes are lowered to the bottom of the hole without winding;
• The ultrasonic probe has small blind area and high power, the signals of four channels are set independently, and the adaptability is strong: the minimum detection distance of the probe is 200mm, and the maximum detection distance is 4000mm; the corresponding hole diameter detection range: dry hole: Φ 600-4500mm, wet hole: Φ400-8000mm; the maximum specific gravity of mud is up to 1.4g/cm3, so it is suitable for detection of almost all engineering holes and trenches;
• The system has a self-calibration function: automatically calibrate the sound velocity of the test system according to the orifice aperture or the trench width, and ensure the accuracy and reliability of the test results;
• The analysis software has powerful functions and rich output results: the host computer analysis software can display, edit and print out the image maps and result charts for the test results, and can automatically determine the position of the hole wall. The output results include color (or gray scale) image map, X-X' and Y-Y' deflection curve, aperture curve and sediment curve, three-dimensional histogram, ranging, aperture and perpendicularity table for each depth measuring point of the whole hole, etc;
• All functions of the probe are perfectly integrated: the multifunctional probe perfectly integrates the functions of ultrasonic aperture perpendicularity detection transducer and sediment thickness detection device. The detection of all parameters is completed in one test, and the detection of aperture, hole deflection and sediment thickness is realized simultaneously;
• Dual parameter control of sediment detection ensures accurate and reliable results: the probe is built with a tilt sensor and a pressure sensor, the ti, the pressure sensor controls the stress of the probe, and the dual parameters jointly determine the sediment thickness to improve the accuracy.
