2.2 Test principle

2.2.1 Cross-hole sonic logging for testing pipe integrity

The basic principle of ultrasonic transmission method for testing

pile integrity is: excite high frequency elastic pulse wave through

ultrasonic pulse emission source, use high precision receiving system

to record the fluctuant features of this pulse wave transmitting in

concrete; when concrete has discontinuous or damaged interface

inside, defect surface forms wave impedance interface, therefore,

when wave arrives to such this interface, caused transmission and

reflection of wave obviously decreases the received transmission

21

Novatest S.r.l.

[e-mail]

Manual for Multichannel Ultrasonic Pile Integrity Tester

energy; when concrete has serious defects such as looseness,

honeycomb or cavitations, wave scattering and diffraction will be

caused; compactness parameters of concrete in test ranges will be

obtained based on the first arrival time of wave and features of

energy attenuation, frequency change and waveform distortion degree,

etc. The property, size and spatial location of internal defect within

concrete could be obtained through treatment and analysis of tested

and recorded ultrasonic fluctuation features in different profiles and

heights.

Before construction of foundation pile, pipes in certain number

according to the pile diameter shall be pre-buried as the channel for

transducer. Every two pieces of pipe is a group in test, ultrasonic

pulse signal is transmitted from transducer in one pipe and received

by transducer in another one through water coupling (as shown in

Figure 2.5), the instrument will record the acoustic parameter such as

acoustic time and amplitude for determining whether the concrete in

this position between two pieces of pipe is normal or not. Move

transmitting and receiving transducers upward from the bottom of

pile and test the points one by one to understand the concrete

integrity of whole profile. Integrity conditions of each profile or even

the whole pile may be obtained through testing all profiles.

test area of structure or structure member, and calculates the concrete

strength in test area through established strength test formula.

Strong relativity exists among the wave speed, rebound value

and strength of concrete; when strength is stronger and wave speed is

faster, the rebound value is higher; after the relationship curve has

been calibrated, test the acoustic time and rebound value separately in

same test area, then calculate the concrete strength by utilizing

established strength test curve (formula 2-1):

The speed of ultrasonic transmission is directly related to concrete

compactness, higher speed means compacter concrete and vice versa.

Ultrasonic method detects concrete defect through relative change of

acoustic parameters such as transmission time (or speed), amplitude

and frequency of received wave of pulse wave in concrete with same

technical conditions to judge the defect of concrete. Since cavitations

or crack may destroy the integrity of concrete, sound wave has to

bypass cavitations or crack and transmit to receiving transducer; the

longer the transmission distance is, the longer the tested acoustic time

is, and acoustic speed decreases correspondingly. Reflection,

scattering and energy attenuation caused by ultrasonic on defect

interface may result in decrease of amplitude; the attenuation degrees

are different when various frequencies in sound wave encountering

defect; high frequency has large attenuation, which makes basic

frequency decreases (frequency shift). Besides, waveform conversion

and addition of sound wave at defect make waveform distortion.
