Description
Technical field
The system of sonic test and sonic test method are conveniently carried out in the borehole the invention belongs to a kind of, as long as aperture
Satisfaction can put test probe into, be applicable to not ensure the water-filled all drillings that drill during test.
Background technology
Sonic test is one of elastic wave testing method, and theoretical foundation establishes the propagation reason in solid dielectric Elastic Wave
By upper, this method is to emit sound wave to medium (rock, rock mass, concrete structures) in the method for electromagnetic exciting, certain
The sound wave of media physical characteristics is received on space length, by observing and analyzing spread speed of the sound wave in different medium, shake
The parameters,acoustics such as width, frequency, the related characteristic of detection medium (rock, rock mass, concrete structures).Sonic detection technology has
It is widely used, achievement is highly practical, does not destroy the advantages that engineering works completely, at home and abroad popularizes rapidly, become should
It is one of main means in China's infrastructural project as quality examination with widest lossless detection method.Therefore,
No matter China obtains major progress in terms of monitoring technology, instrument and equipment, making the technology, many construction projects are extensive at home
It promotes and applies, is improving construction quality, removing a hidden danger, ensures that secure context has played great function.
Sonic test is often to be detected in drilling in media as well, sonic probe is put into specific engineer application
After in hole, it is desirable that the outer surface whole medium hole wall good contact of transmitting probe and receiving transducer, could obtain both stabilizations has standard
If true test result is extremely difficult without the help of couplant.In order to ensure good contact, it is necessary to visit
Full of couplant between head and hole wall, verify that water is ideal couplant by engineering practice in decades.Mesh
In preceding sonic test, take in hole full of water, using water as couplant, be commonly used method, but enclosed in complexity
Under rock condition and test environment, in large-section underground cavern and tunnel, following several situations are frequently encountered：It is (1) anhydrous in hole,
That is dry hole, (2) even if there is underground water, but without full of instrument connection, (3) flat hole and uphole, existing in (4) total drilling section strong and weak
Permeable perforated section.Several situations more than running into, just must the water filling constantly into hole, aperture carries out water blockoff, ensures water full of entire
Drilling, when needing to carry out the test of tens hole sections in a drilling, it is necessary to the water filling of tens times, water blockoff circulate operation,
Extremely time-consuming, laborious, when running into uphole or the drilling of highly permeable perforated section, operation is just more difficult, and case above greatly limits
The popularization and application of sonic test technology at the scene.
It is mainly solved the above problems both at home and abroad on sonic test by two kinds of approach, the first approach is not make at present
With couplant, increase focus transmission power in transmitting probe or set in receiving transducer installation signal amplification, improve and receive signal
Ability.This method can be tied and solved the problems, such as to a certain extent, but working practice shows that monitoring effect is unsatisfactory, former
Because being to increase transmission power, but due to detection system couple with hole wall it is bad, transmitting terminal energy before entrance detection body just
Loss is totally；And enhance and receive signal, it is easy to be disturbed be subject to ambient noise.Second of approach is from sonic probe and hole wall
Coupling is started with, and has port closing method, and starting point is to make to form confined space in hole, it is therefore an objective to the water of injection be made to ensure full of test
Hole, this method port closing equipment is fixed, when needing to do the sonic test at multiple positions in a hole, mobile sonic probe pole
For inconvenience, sonic probe is moved close to orifice position when being tested, if entire instrument connection hole wall has one section, there are larger
Permeable crushed zone when, it is necessary to water injection rate is increased, otherwise it is difficult to ensure that water is full of in hole.
