Make hoop motion detection device at the uniform velocity move, until hoop motion detection device moves to the other end of hoop track, i.e. complete
Detection to shield tunnel the first ring lining quality；
7th step, constantly advancing along with the detection chassis in the machinery automatically detecting shield tunnel liner construction quality,
Vertically move detection device by regulation, make hoop motion detection device be positioned at next lining papers and build at cross-section center axis, depend on
Secondary repetition the 5th step and the 6th step, i.e. complete the detection work of follow-up lining quality.
Detection method the most according to claim 8, it is characterised in that in the first step:
Described radar antenna spatial resolution X refers to: the echo that two objects produce on radar screen can distinguish
The minimum actual range come, according to the needs to accuracy of detection, takes 0.01-0.1m；
Described two-way travel time t refers to: electromagnetic wave sends from radar antenna and arrives objective body anti-from objective body through medium
Being emitted back towards the time of this process of radar antenna, i.e. electromagnetic wave and returns through the thickness of prefabricated pipe section from the one side of prefabricated pipe section
Time；
Velocity of electromagnetic waves v in described lining cutting determines as follows:
The mid frequency f of described radar antenna determines as follows:
In formula, d is prefabricated pipe section thickness (m)；T is two-way travel time (ns)；X is radar antenna spatial resolution (m)；ε is
Relative dielectric constant, in citation criteria TB 10223-2004, computing formula is:
Detection method the most according to claim 9, it is characterised in that in the 6th step, described hoop motion detection device speed
Degree vrDetermined by following formula:
Wherein: α is regulation coefficient, takes 0.3-0.6；ε is relative dielectric constant；S is that radar scanning speed, i.e. radar antenna are per second
The umber of pulse launched, secondary/s；F is the mid frequency MHz of radar antenna；V is the velocity of electromagnetic waves m ns in lining cutting-1。
