The specific embodiment
As shown in Figure 2, present embodiment leaves the hollow drill pipe 6 of an internal diameter 61mm in the boring of aperture 75mm, and the drilling rod lower end is connected with the drill bit 3 of internal diameter 49mm.This example is salvaged core outside the hole with fisher earlier before carrying out packer permeability test, on carry drilling rod 6 the long boring test section 1 of 5m～10m be set, drilling rod 6 is suspended in the boring by aperture clamper 7.A suspention part is positioned at drilling rod at drill bit 3 places, another part stretches out the outer packing device 2 of drill bit, the top of packing device 2 is connected with the high-pressure pump 12 (or Manual pressure test pump) of boring outside by the high-pressure rubber pipe 10 of external diameter 16mm, internal diameter 6mm, and the aperture locking device 9 of band setting-out water inlet 9-1 is equipped with in the aperture, ground of drilling rod.
As shown in Figure 1, described packing device 2 comprises the high-pressure rubber hose coupling 2-1 that links to each other with high-pressure rubber pipe 10, and this joint is fixed on the top connection 2-3 of annulus cylindricality.And Φ 14 * 2mm seamless steel pipe 2-4 of a up/down perforation of welding on the axis of top connection, seamless steel pipe overcoat pneumatic hose 2-5, pneumatic hose one end and top connection 2-3 snapping, the other end interlocks with the lower contact 2-8 that is enclosed within the annulus cylindricality on the seamless steel pipe, plug 2-9 and lower contact 2-8 screwed connection, and lower contact and plug can slide along seamless steel pipe.At pneumatic hose 2-5 middle part the stop collar 2-6 that mates with its external diameter is housed also, stop collar external diameter 47mm, it can engage to play the positioning action to packing device with drill bit 3.The end of seamless steel pipe 2-4 is installed suspension ring 2-2, and the O type circle 2-7 of Φ 18 * 2.4mm is equipped with in the other end and described plug 2-9 cooperation place.Wherein, suspension ring can make things convenient for the placement and the lifting work of this packing device 2; The O type encloses sealing function, can prevent to leak gas or leak.
This packing device has the pressurized sebific duct and expands, the function that the decompression reduction is shunk, and according to " water power hydraulic engineering water pressure test in borehole rules (DL/T5331-2005) " rules requirement, conventional maximum packer permeability test pressure is P
Examination=1MPa.For making packing device can reach the stagnant water effect of expection, the packing device length overall is 180～200cm, and is cylindrical, wherein: pneumatic hose 2-5 length overall 150～170cm, after finishing, assembling stretches out the long 80cm of pneumatic hose outside the drill bit 3, and remaining is stayed in the drilling tool.Top connection 2-3 external diameter can be slightly larger than the external diameter of pneumatic hose; Lower contact 2-8 external diameter must be less than the internal diameter of 75mm wire line coring drill bit (3).This example is 42mm.This packing device bulbs of pressure should surpass 1.8～2 times of maximum packer permeability test force value, for this reason, the rated pressure P of used high-pressure rubber pipe 10, high-pressure pump 12 should consider the safety factor more than 2 times again, promptly selected rated pump pressure, high-pressure rubber pipe is withstand voltage all should 〉=4MPa.
As shown in Figure 3, operating principle of the present utility model is: charge into air for packing device 2 by high-pressure pump 12, outwards expand behind the pneumatic hose 2-5 pressurized, this sebific duct lower end drive lower contact 2-8 and plug 2-9 upwards shrink (general simultaneously, when high-pressure pump pressure meter 13 pointers were between 1.8～2.0MPa, pneumatic hose shrank 20cm).When pressure meter 13 showed greater than 1.8～2 times of maximum test pressures, pneumatic hose 2-5 had been close on the hole wall 5, and the water outside the test section is isolated fully, and air pump stopped to pressurize and possessed the condition of doing packer permeability test this moment.
Packer permeability test: with creeping into water pump by sebific duct water filling in the setting-out water inlet 9-1 of aperture locking device 9, current enter boring test section 1 by seamless steel pipe 2-4, under the condition of waterflow stabilization, every 3min～5min surveys and reads once to be pressed into flow, and continuous four readings meet the setting-out requirement and finish test again.Open the Air control valve 11 of high-pressure pump after the off-test earlier, make the pneumatic hose pressure release, pneumatic hose just can recover original form by self elastic force after the pressure release, removes aperture locking device 9, manually lifts suspension ring 2-2, and packing device 2 is taken out outside the holes.
Be not difficult to find out by above content, in the boring of aperture 75mm wire line coring, utilize the utility model packing device, need not to pull out of hole and just can finish packer permeability test, alleviated the labour intensity that makes a trip greatly.
