Description
Technical field
The invention belongs to mine water damage Prevention Technique field, it is related to block using both-end capsule in the borehole and gives stratum water filling
Device/system.
Background technology
" drilling double-end sealing leak detection " is that one kind carries out pressure water injection, basis by special equipment in roof drilling
High measuring technology is split in practicality of the change of water filling wastage to determine height of water flowing fractured zone before and after the wall of a borehole rock mass damage.
Fig. 1 shows a kind of borehole two-end seal leakage detector (referring to " drilling double-end sealing leak detection " method in coal work
Application in facial cleft height test, Bao Jinglong etc.,《Colliery engineering》4th phase in 2011 (the 4th phase of volume 30)), it can be used to survey
The height of colliery " two bands " is measured, the device plugging device, connecting line and the part of hole external pelivimetry instrument three in hole are constituted.Sealed in hole
Stifled device is a water filling inserting tube that capsule is blocked with both-end, for being sealed to tested hole section two ends；Tester outside hole
Table mainly includes flowmeter, pressure gauge and corresponding valve, to control sealing of hole pressure and water injection pressure and injection flow size,
Connected outside hole in instrument and hole between plugging device by pressure-resistant connecting line.When water filling is observed, both-end plugging device is loaded and drilled, it is double
Pipe state is usually presented in the capsule of end plugging device, can be moved freely in drilling.When being filled with a level pressure to capsule by pipeline
When the water or gas of power, capsule is expanded rapidly at once, and hole section two ends where plugging device are tightly blocked, then by water injecting pipeline from
To closure hole section water filling in the middle part of inserting tube.If there is crack the rock stratum of closure, the water of injection hole section will be missed from crack, pass through hole
External flux test instrumentation, can measure every metre hole section, the wastage in the time per minute under regulation water injection pressure.Wastage size
Reflect the development degree in block section crack.
The characteristics of device, is as follows：
1) capsule feeding mode
Realize capsule feeding with rising using rig.
2) capsule expansion fashion
Have in hole expands capsule in the case of water by water filling, and capsule is expanded by inflation when anhydrous in hole.Capsule is swollen
It is swollen to use special water filling or gas injection pipeline with pressure release.
3) capsule and water filling section water flooding regime and conversion
Capsule is swollen to be controlled respectively with borehole test section water filling using 2 sets of independent pipe-line systems, i.e. capsule expansion is with letting out
Pressure uses special water filling or gas injection pipeline.
As can be seen here, the limitation of the device mainly has：
1) capsule water filling uses independent high pressure water injection/air pipe with stratum water filling, and investigation depth is limited, and easily occurs thing
Therefore.
Due to being supplied using independent pipeline to capsule in water/gas, i.e. hole except the water system supplied water to water filling section (is bored
Bar) outside, also one is played the swollen pipe-line system (generally high-pressure hose) used for capsule.Pipeline is more in hole, in hole simultaneously
There is drilling tool and capsule, easily occur high pressure software winding drill stem, the accidents such as drilling are blocked, due to having the presence of high-pressure hose, hole
It is deep bigger, occur, because the accident probability of flexible pipe blocking is bigger, to limit borehole test depth, be limited investigation depth.
Such as it is intended to use 1 circuits while realizing capsule water filling and stratum water filling, then needs design capsule water filling and stratum note
The switching mode of water, and ensure the conversion effect of capsule and stratum water filling.
2) capsule rises swollen with shrinking more, the complex operation in aperture operating desk operation aperture pipeline and instrument.
3) water burst water is larger in hole, and can not be tested when there are water pressures.
The content of the invention
Present inventor devises both-end in a kind of hole and sealed on the basis of the above mentioned problem in view of prior art
Stifled water filling device, wherein, capsule uses same circuits with stratum water filling, on the one hand makes capsule tripping in acting facility, prevents
The accident caused in the past by independence to the pipeline that capsule supplies water, on the other hand makes the increase of detection hole depth；Orifice devices are succinct, operation
It is easy；It is larger and have stratum water filling in the case of water pressure using the complete equipment water burst water that can carry out drilling.For switching glue
The use of capsule water filling and the switching valve of stratum water filling is easy to operate, conversion effect is reliable.
Embodiments in accordance with the present invention there is provided a kind of borehole two-end seal leakage detector, including water filling/pressure relief system,
Water filling switching system, wherein, the water filling/pressure relief system include water filling pressure duct, pressure relief pipe, for by water successively via
Water filling pressure duct, drilling tool, switching valve are injected into capsule or formation testing section.The water filling switching system includes being used to block ground
Capsule, switching valve, the stratum water injection pipe at layer test section two ends, for by stratum water injection pipe carry out formation testing section water filling or
Capsule water filling is carried out by water filling pressure duct, wherein, the water inlet of switching valve is connected to the delivery port of drilling tool, for described
Switched between formation testing section water filling and the capsule water filling.
The present invention mainly has the advantages that：1) capsule expansion uses same set of water filling system with test section water filling
System, is eliminated individually for the swollen water filling of capsule or gas injection system, is eliminated because drilling accident occurs for pipeline winding, blocking
Hidden danger；2) switching valve is used, the mechanical switch for realizing switching valve is moved up and down by drilling tool, effect is relatively reliable；3) capsule by
Drilling rod is sent into, and overcomes macropore deep investigation problem；4) in hole water larger (such as 10~20m3/h), hydraulic pressure it is larger (such as 2~
Still it is applicable when 4MPa)；5) aperture connection is simple and convenient to operate.

Time interval is 5min, and performs record.Water in synchro measure hole.
In addition, by-pass switch can be installed in parallel with water meter, it is for switching water discharging, Water Sproading to water tank is sharp to repeat
With.
After first water pressure state water filling terminates, changed by the regulating valve adjusted on water injecting pump to second water pressure
State, water filling observation operation is required ibid.Tested successively afterwards, at the same should under each water pressure state water in measured hole
Amount.
2nd, brill is moved back in pressure release
1) after the test of pressure water terminates, the water pressure of water filling stratomere should be let out first with the stop valve of aperture water pipe.Afterwards
Water in measured hole.
2) drilling tool is above pushed away to 5cm, by conversion threshold switch conversion, now floral tube is in closed mode, and switching valve is connected with capsule.
Capsule pressure release is made by stop valve water outlet, 2~3min should be continued.It is synchronous to carry out drilling tool lower end and the dismounting of water filling pipe connections.
3) capsule is delivered into next test section and tests or exit drilling tool and capsule etc..
4) drilling tool, capsule are withdrawn from after drilling in hole, survey water.
Illustrate the structure and operation principle of switching valve below.
