To, laterally detection is carried out repeatedly to the suspicious region (D) to be detected with repeatedly vertical, aobvious by described output display part (16)
The final signal data of the electromagnetic wave of suspicious region are shown, wherein, adjacent horizontal twice detection and adjacent vertical twice detection
Spacing is 1-50 centimetre；
Step 5：Standard final signal data by electromagnetic wave in the final signal data of the electromagnetic wave of suspicious region and step one
It is compared, draws the mud jacking degree of compaction situation of the suspicious region (D) place prestress pipe.
6. the method for the mud jacking degree of compaction of Non-Destructive Testing prestress pipe according to claim 5, it is characterised in that described
When the equipment of the mud jacking degree of compaction of Non-Destructive Testing prestress pipe is detected, the electromagnetic wave launched by transmitting antenna (11)
Predeterminated frequency be 500MHz-3GHz.
7. the method for the mud jacking degree of compaction of Non-Destructive Testing prestress pipe according to claim 5, it is characterised in that described
In step 2 and the step 4, the electromagnetic wave for reflecting is processed through A/D converter (14) and data processor (15)
Output display is carried out afterwards through output display part (16), specifically again：
Step a：Voltage signal received by the reception antenna (12) is converted to digital letter by A/D converter (14)
Number, the digital signal includes that the wave spectrum of the velocity of wave of electromagnetic wave, the intensity of electromagnetic wave, the frequency of electromagnetic wave and electromagnetic wave is special
Levy；
Step b：Data processor (15) are processed to step a gained digital signal, specifically：First by digital signal
In the data that belong to beyond predeterminated frequency scope rejected, then the noise included in digital signal is carried out suppressing, is eliminated
And smoothing techniques.
8. the method for the mud jacking degree of compaction of Non-Destructive Testing prestress pipe according to claim 5, it is characterised in that described
The final data and normal data of step 2 are compared specifically in step 3：First by the electricity of step 2 gained final data
Waveform characteristics and phase place change in the phase place change of the waveform characteristics and electromagnetic wave of magnetic wave and normal data are compared, if ripple
The coincidence degree of shape intensity and phase place change is more than or equal to 98%, then judge that detection zone belongs to dense region, otherwise, it is determined that inspection
Survey region and belong to doubtful leakiness region.
9. the method for the mud jacking degree of compaction of Non-Destructive Testing prestress pipe according to claim 5, it is characterised in that to institute
State when suspicious region (D) carries out repeatedly horizontal detection and multiple vertical detection and the slide calliper rule and the graph paper (2) are coordinated
Use.
10. the method for the mud jacking degree of compaction of Non-Destructive Testing prestress pipe according to claim 5, it is characterised in that institute
Stating in step 5 by more specific to the final data of the electromagnetic wave of suspicious region and normal data is：Electromagnetic wave by suspicious region
Final data and normal data in the velocity of wave of electromagnetic wave, the frequency of electromagnetic wave, the waveform characteristics of electromagnetic wave and electromagnetic wave
Phase place change be compared respectively, the weighted mean of acquisition coincidence factor, you can obtain suspicious region (D) place prestressing force
The mud jacking degree of compaction situation of pipeline.
