Description
Technical field
This utility model belongs to technical field of geophysical exploration, is specifically related to a kind of dry hole sound wave water spray coupling measurement
Device.
Background technology
The engineering utilizing boring to carry out testing in engineering investigation is a lot, but owing to many boring exists seepage, anhydrous in hole
Deng liquid medium, often many borings or hole section cannot be carried out sonic test work due to seepage hydropenia, thus lose acquisition
The chance of borehole sonic data.
Such as, the China of Publication No. CN202649477U discloses a kind of acoustic detecting head of dry hole wall attaching device, including one
Individual acoustic emission probe and two acoustic receiver probes, acoustic emission probe is gone here and there before and after using wire with two acoustic receiver probes
Connection, respectively sets a shell fragment snap ring on acoustic emission probe and first acoustic receiver probe, and each shell fragment card is equipped with stainless
Steel bomb sheet, the lower section being positioned at each rustless steel shell fragment on wire respectively sets a magnetic apparatus, and magnetic apparatus meets 12V by connecting cable
Storage battery.Owing to probe can be attached on hole wall, carrying out sound wave that the probe of acoustic emission during sonic test launches can be along hole wall
Rock mass is propagated and is received by two acoustic receiver probes, thus reaches to test the quality condition of hole wall rock mass.This dry hole
Sonic probe wall attaching device only solves the problem of the adherent quality of sonic probe, but unresolved main water coincidence problem.
In test, there is water and without water coincidence, the general difference of sonic propagation energy times～decades of times.Therefore this technical scheme, nothing are used
Water coincidence majority of case cannot complete sonic test.
For another example, the Chinese patent of Publication No. CN200986538Y discloses a kind of novel dry hole acoustic wave testing probe.Dry
Hole sonic probe is made up of sonic probe and pressurization water pocket, and sonic probe is respectively arranged at two ends with water supply connector and exhaustor, is entering
Setting water stopping trough on the extexine of water swivel and exhaustor respectively, pressure (hydraulic) water cuff is contained in sonic probe and water supply connector and exhaustor
Outward.The first port footpath of the steam vent being opened in exhaustor and the ratio of end bore are 10: 1.This acoustic detecting head of dry hole can be effective
Ground couples with the hole wall of tested dry hole, and in dry hole, local is created one and is similar to the environment of couplant (such as water).This sound
The deficiency of ripple test probe mainly has the coupled problem of pressurization water pocket and dry hole wall, and sonic probe moves up and down inconvenience.On the one hand,
If pressure (hydraulic) water bag pressure power is bigger, it is ensured that pressurization water pocket and dry hole wall efficient coupling, but now pressurization water pocket is difficult to mobile or nothing
Method moves；On the other hand, if pressure (hydraulic) water bag pressure power is less, pressurization water pocket can move, and now pressurize water pocket and dry hole wall coupling
Closing poor, acoustic signals is more weak or is difficult to receive acoustic signals.
Utility model content
