Also ultrasound checking inside concrete quality or defect, the technology of homogeneity of concrete and requirement are detailed.So carry out ultrasound
The quality problems of ripple detection concrete filled steel tube are the widest methods of real project.But examined using ultrasonic wave
Many problems are but run into during survey concrete filled steel tube internal soundness or defect, wherein placing transmitting-receiving in CFST Arch Bridge
Transducer is difficult to realize, reason is that arch bridge is higher, and working face is small, and concrete filled steel tube is mostly irregular steel pipe parcel, no
It is easily placed transducer.There is presently no the device that can conveniently place transducer.
When at this stage using ultrasonic wave detector detection concrete column structure, handheld transducer is used to detect.This detection
Method has the disadvantage that：
1. because the arch rib of arch bridge is in high-altitude, therefore handheld transducer is very inconvenient during detection, typically using loop wheel machine
People is sling and carries out placement transducer, this forbids during practice of construction.Or workmen lies prone at arch rib staircase
Body detects downwards, and action is extremely dangerous.
2. handheld transducer survey can not be carried out multi-section to surveying, therefore detection sectional plane is less, it is impossible to represents comprehensively whole
Section, precision are relatively low.
3. handheld transducer detection workload is big, typically it is not timely completed.Easily by such environmental effects.
