10. a kind of sound detecting pipe is bent Correction of Sound Velocity, this method uses sound as in one of claimed in any of claims 1 to 9
Test tube is bent velocity of sound correcting device, it is characterized in that：The method includes the following steps：
S1, the acquisition of deviational survey data：By two probes, slowly decentralization to two sounding bottom of the tube, sliding pearl control two spies respectively respectively
Head is in two sound detecting pipe centers, and the deviation survey equipment on two probes obtains the deviational survey number of two sounding tube hubs respectively
According to by connecting cable respectively by deviational survey data transmission to computer, the spatial distribution curve of two sounding tube hubs of acquisition；
S2, surveyed section threedimensional model is established：Clear distance between two sounding pipe outer walls at accurate measurement stake top inputs sonic detection
Instrument, the computer in sonic wave detector combine the inside and outside diameter data of two sound detecting pipes inputted and are acquired by step S1
Two sound detecting pipe central space distribution curves establish the threedimensional model of surveyed section；
S3, sound transit-time measurement：During at the uniform velocity promoting two probes in two sound detecting pipes at the same time, computer controls high pressure
It penetrates and control module, generation controlled high-voltage pulse encourages the transceiver in a certain sound detecting pipe on probe by connecting cable
Energy converter, after converting electrical energy into ultrasonic pulse, the couplant and sound detecting pipe wall that pass sequentially through in sound detecting pipe are passed to pile body coagulation
Soil, the transceiver energy converter on probe in another sound detecting pipe, which receives, sequentially passes through concrete, sounding tube wall harmony test tube
In couplant ultrasonic signal after the signal is reconverted into electric signal, the journey being transmitted to through connecting cable in sonic wave detector
After control amplification is automatically adjusted the electric signal with attenuation module, it is delivered to A/D conversions and acquisition module, A/D is converted and adopted
Transformed digital signal is transmitted to after controller test value when sound is calculated by collection module again, deduct test system delay,
When geometrical factor sound after correction value, when obtaining the propagation sound that survey line is in concrete medium；
S4, the velocity of sound calculate：During at the uniform velocity promoting two probes in two sound detecting pipes at the same time, computer is according to step S2
Depth residing for the surveyed section threedimensional model of foundation and two probes, extracts survey of the surveyed section at each survey line
It is true at each survey line of surveyed section to be calculated when away from, the propagation sound being in conjunction with surveyed survey line in pile concrete
The real velocity of sound.
