The invention relates to a multi-cross-hole ultrasonic detection system and a detection method thereof. The detection system comprises a plurality of probes, a depth meter, a high-voltage pulse generator, a signal conditioning analog-digital converter, an ultrasonic logic control module and a host computer, wherein a plurality of wiring grooves are formed in the depth meter; cables of the probes are arranged in the wiring grooves; each probe comprises an ultrasonic transmitting transducer and an ultrasonic receiving transducer; the ultrasonic logic control module is used for receiving configuration information through the host computer and controlling the high-voltage pulse generator to send a high-voltage pulse to the ultrasonic transmitting transducer of the corresponding probe according to the counting information from the depth meter; the signal conditioning analog-digital converter is used for performing amplification, filtration and analog-digital conversion on a signal of the corresponding ultrasonic receiving transducer; the ultrasonic logic control module is capable of obtaining an output signal of the signal conditioning analog-digital converter and displaying the output signal on the host computer. Holohedral-symmetry transmitting and receiving modes are adopted by the probes, the external probes can be used in mixing at random and great convenience is brought for the use of users.
Description
technical field [0001] The invention relates to ultrasonic detection of foundation piles, in particular to a multi-span-hole ultrasonic detection system and a detection method thereof. Background technique [0002] At present, one instrument of the existing multi-channel (multi-cross-hole) ultrasonic testing system can only be used for the detection of a certain type of foundation pile. For example, a three-channel ultrasonic detector can only be used to detect foundation piles with three holes, two None of the four holes can be detected, so a certain testing unit must buy three kinds of instruments to cope with the ultrasonic testing of various foundation piles, wasting resources and funds. [0003] At present, the existing multi-channel (multi-cross-hole) ultrasonic testing system takes four channels as an example, that is, there are four probes. Such as figure 1 As shown, when probe 1' transmits, probes 2', 3', and 4' receive; when probe 2' transmits, probes 3' and 4' r...
