Abstract
The utility model relates to a novel dry hole acoustic detection probe, which belongs to the field of fabrication of engineering nondestructive test devices. The dry hole acoustic probe comprises an acoustic probe and a pressurized water bag. The two ends of the acoustic probe are separately provided with a water inlet joint and an exhaust pipe, and the outer surface of the water inlet joint and the exhaust pipe are separately provided with stanching pits. The pressurized water bag is sleeved on the acoustic probe and out of the water inlet joint and the exhaust pipe. Ratio of the front end diameter of the exhaust hole to the back end diameter of the hole arranged on the exhaust pipe is 10:1. The utility model can be effectively coupled with the wall of the to-be-measured dry hole to create an environment similar with filled with coupling media (e. g. water) in some part of the dry hole, and thus substantially solves the technical problems of dry hole acoustic detection. The utility model is characterized in reasonable structure, simple and quick use and assurance of detection of transmission and receiving effects of the sound wave.
Description
Technical field
The utility model relates to a kind of novel dry hole sonic test probe, belongs to the engineering non-destructive detecting device and makes the field.
Background technology
Sonic test is one of elastic wave method of testing, its theoretical foundation is based upon the solid dielectric ELASTIC WAVE PROPAGATION in theory, this method is to launch sound wave with the method for electromagnetic exciting to medium (rock, rock mass, concrete structures), the sound wave of receiver media physical characteristics modulation on certain space length, by observation with analyze parameters,acoustics such as the velocity of propagation of sound wave in different medium, amplitude, frequency, solve the relevant issues in the Geotechnical Engineering.
That the sonic detection technology has is of many uses, achievement is practical, do not destroy advantages such as engineering works fully, penetration and promotion at home and abroad rapidly, becoming most widely used lossless detection method, is as one of topmost means of quality check in China's infrastructural project.Therefore,, make this technology each construction project wide popularization and application at home, improving construction quality, removing a hidden danger, guarantee that secure context brought into play huge effect no matter China is all obtaining major progress aspect detection technique, the instrument and equipment.
Because it is good with the hole wall coupling simultaneously that sonic detection must guarantee transmitting probe and receiving transducer, cause the application of this technology in dry hole to be subjected to very big restriction, and in engineering reality, the dry hole that needs to detect often runs into, this has just limited it greatly and has solved the scope of engineering problem, as: the underground cavern excavation of large span is more general in all kinds of engineerings, for detecting the lax band of country rock after excavating, guarantee that cavern's construction safety need utilize sound wave that cavern's crown relaxation zone is detected, some sidewall and base plate boring, because of structure, broken, incessantly water is also deposited in the lax influence of explosion, so, it is particularly important to seek a kind of solution dry hole sonic test method rapidly and efficiently, and it indicates the raising that solves engineering problem and comprehensive.
Realize by the following method mainly both at home and abroad that at present dry hole detects: (1) is the angle of focus from transmitting terminal, adopts and strengthens focus emissive power (giant magnetostriction seismic source), forces receiving transducer and hole wall coupling (not adopting couplant).(2) enhancement process of received signal, the preposition amplification of receiving end band, enlargement factor reaches 20-50 doubly.Two kinds of methods can both be dealt with problems to a certain extent, but working practice shows, it is unsatisfactory to detect effect, sometimes even detect less than signal.Trace it to its cause for: though strengthened the focus emissive power, because the coupling of detection system and hole wall is not good, the transmitting terminal energy had not lost totally before entering the detection body; And the enhancing received signal under the very faint situation of useful signal, is easy to be subjected to the interference of ground unrest.So the key of guaranteeing dry hole sonic detection effect makes it adapt to the requirement that dry hole detects to designing a kind of novel dry hole sonic test probe, will play the detection effect of getting twice the result with half the effort predictably.The key problem of dry hole test is the coupled problem that how to solve sonic probe and hole wall, and guarantees to detect sonic propagation, reception.
Summary of the invention
At above-mentioned existing problems, the purpose of this utility model is to provide a kind of novel dry hole sonic test probe that makes things convenient for the dry hole sonic test, its technical scheme is as follows: acoustic detecting head of dry hole is made up of sonic probe and pressurization water pocket, the sonic probe two ends are respectively equipped with water supply connector and gas outlet, establish water stopping trough on the extexine of water supply connector and gas outlet respectively, the pressurization water pocket is sleeved on outside sonic probe and water supply connector and the gas outlet.Open the first port footpath of vent port in gas outlet and not the ratio in port footpath be 10: 1.Be provided with inlet opening and sound wave signal cable passage in the water supply connector.
Owing to adopted above technical scheme, acoustic detecting head of dry hole of the present utility model can be effectively and the coupling of the hole wall of tested dry hole: by carry current in the pressurization water pocket, water pocket is expanded in pressurization, makes the interior detection system of gaging hole closely adherent; The air that pressurization produces in the water pocket is got rid of automatically by the vent port that is provided with by system, outside a spot of current discharge of while system, serves as couplant at hole wall rock mass and water pocket outside surface.A kind of environment that is similar to couplant (as water) is created in the part in dry hole, has fundamentally solved the technical matters of dry hole sonic test.Acoustic detecting head of dry hole of the present utility model, rational in infrastructure, easy to use quick, can guarantee to detect sonic propagation, reception.
