In this way, to complete a complete hole-forming construction quality inspection task, it is necessary to prepare multiple sets of different equipment. During the inspection process, it takes more time to replace different equipment, which affects the construction progress.
[0004]In addition, the existing methods for detecting the thickness of sediment at the bottom of the hole include the stylus cake measurement method with inclination angle measurement, which uses an inclination sensor to measure the inclination angle of the probe in real time and upload the To the detection instrument, the inclination-probe extension length curve is displayed in real time, and the inflection point where the angle suddenly becomes larger is found from the inclination curve. The probe extension length corresponding to the inflection point is the thickness of the sediment. Probe detection range
However, this method has the following disadvantages: when the sediment surface is very flat, the stylus is pressed against the hard rock and the probe is jacked up. If the probe is not obviously inclined and the inflection point of the inclination curve has no obvious change, it will be misjudged that the thickness of the sediment exceeds the probe. Needle detection range; when the surface of the sediment is very uneven, the initial inclination angle of the probe will be very large. When the probe is working in an inclined state, the probe will incline to a larger angle when the probe encounters a slight resistance, which will cause misjudgment on the inclination curve has reached the lower surface of the sediment
Therefore, the measurement results of this method are neither reliable nor accurate
