Technical field
The present invention relates to bored grouting blocking technology field, specifically the pressure relief vent inner sleeve slip casting of gushing water borehole wall filter stream
Gu pipe plugging device.
Background technology
In mine down-hole produces, usually can run into the gushing water problem of water under high pressure boring, the close bad exploration disclosed such as down-hole
Hole, freezing hole, inspection hole etc., and the exploratory hole of aperture outburst prevention measures inefficacy (containing without outburst prevention device) of underground construction, inspection
Look into hole etc..Underground work environment, if do not blocked, is on the one hand impacted, strengthens mine drainage burden by this kind of boring；
On the other hand just bring bigger water yield in the short time, Mine Safety in Production is threatened.
The underground for probing drilling construction that discharges water is that complicated hydrogeological conditions mine water disaster administers conventional measure, but often occurs owing to containing
Water layer hydraulic pressure is high, mine crustal stress is big, boring base plate lithology is poor, probing is not in control what the factor such as position or casing corrosion caused admittedly
Underground for probing discharge water borehole casing rupture, bad break, in hole at big flow, water under high pressure bad break sleeve pipe with superficial part crack, tunnel turn on,
Cause borehole circumference Floor Heave in Roadway, water inrush accident.
This type of accident not only brings threat to mine safety production, also add drainage underground expense, improves the production of mine
Cost.This type of accident treatment must block water outlet boring in time, owing in hole, the water yield pours out through periphery tunnel superficial part base plate
Pressure release, when using the conventional direct slip casting method in aperture, serosity is at casing-broken and tunnel superficial part Water Inrush point pours out,
Cause boring to block, be badly in need of a kind of new solid pipe, slip casting plugging technology.

Prior art of the present invention is compared, and has the advantages that
This technique, by entering small-bore inner tube under in outer tube (borehole casing) to below casing-broken, utilizes inner tube in hole
Slip casting (aggregate, cement mortar), and install filter screen additional at pore wall pressure release outside, prevent aggregate from running leakage, serosity (aggregate, water
Mud) first after penetrating into closure roadway floor water outlet crack passage at casing failure, utilize the principle of aggregate water-swellable, or
Cement mortar enters in roadway floor gap under pressure, it is achieved the closure to roadway floor；And then by between inner and outer pipe
It is filled with night, it is achieved Gu the solid pipe of pipe, when needing plugging water-bearing stratum, by inner tube slip casting, plugging water-bearing stratum can be realized.
Whole process operation is simple, and closure success rate is high, admittedly manages and realize borehole sealing and roadway floor reaching inner and outer pipe
The purpose of the improvement of water.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gushing water borehole wall of the present invention filter solid pipe plugging device of stream pressure relief vent inner sleeve slip casting.
Detailed description of the invention
By making the architectural feature to the present invention and effect of being reached have a better understanding and awareness, in order to preferably to implement
Example and accompanying drawing coordinate detailed description, are described as follows:
As it is shown in figure 1, the gushing water borehole wall filter solid pipe plugging device of stream pressure relief vent inner sleeve slip casting, including outer tube 1.Outer tube 1
Have at bad break 11；Hole wall filter stream pressure relief means thereon 2 it is provided with at the mouth of pipe of outer tube 1；Hole wall filter stream pressure relief means thereon 2 has
Charging aperture；It is inserted into inner tube 3 to outer tube 1 by the charging aperture of hole wall filter stream pressure relief means thereon 2；At bad break, 11 are in inner tube 3
Between two ends；It is further fixed on feed pipe 4 at the charging aperture of hole wall filter stream pressure relief means thereon 2.Unload with hole wall filter stream at feed pipe 4
Being also equipped with aperture gate valve 5 between the import of press mechanism 2, it is to avoid serosity adverse current, aperture gate valve 5 is with outer tube 1, inner tube 3 even
Logical, it is to avoid serosity adverse current.
For solid pipe, between outer tube 1 inwall and inner tube 3 outer wall, there is gap, it is simple to slip casting or aggregate, in order to demeanour tunnel
Floor joint.
The hole wall filter stream pressure relief means thereon 2 that the present invention provides includes filter stream relief tube 21, installs on the tube wall of filter stream relief tube 21
There is pressure-relief valve 22；Between the tube wall of pressure-relief valve 22 and filter stream relief tube 21, filter screen 23 is installed, prevents aggregate from running leakage.This
Invent the lateral symmetry at filter stream relief tube 21 and described pressure-relief valve 22 and described filter screen 23 are installed.
Aperture inlet valve 6 is installed at the aperture of feed pipe 4, in order to control charging.
The solid pipe method for blocking of a kind of gushing water borehole wall filter solid pipe plugging device of stream pressure relief vent inner sleeve slip casting, including following step
Rapid:
Step 1. installs hole wall filter stream pressure relief means thereon additional
Hole wall filter stream pressure relief means thereon 2 is installed at outer tube 1 mouth of pipe；
Step 2 installs inner tube additional
It is inserted into inner tube 3 at outer tube 1, makes at the bad break of outer tube 1 11 to be between inner tube 3 two ends；And the mouth of pipe of inner tube 3
Flush with the throat-fed mouth of hole wall filter stream pressure relief means thereon 2；
Step 3. installs feed pipe additional
At the charging aperture of hole wall filter stream pressure relief means thereon 2, feed pipe 4 is installed；
Step 4. roadway floor blocks
Slip casting in gap between outer tube 1 and inner tube 3, makes inner tube 3 and outer tube 1 be combined as a whole；And serosity is through mistake
Disconnected place 11 infiltration roadway floor water outlet crack passage blocks；
Step 5.
Slip casting in the gap between outer tube and inner tube, is outer tube and inner tube is integrally forming；
Step 6. borehole sealing
To inner tube 3 slip casting, it is achieved to borehole sealing.
The present invention uses serosity to be generally cement mortar, and aggregate is generally Semen Glycines or broken dry Thallus Laminariae (Thallus Eckloniae).Semen Glycines and broken dry Thallus Laminariae (Thallus Eckloniae) warp
Send out after crossing blister and rise, thus realize the closure to tunnel floor joint.
This technique, by entering small-bore inner tube under in outer tube (borehole casing) to below casing-broken, utilizes inner tube in hole
Slip casting (aggregate, cement mortar), and install filter screen additional at pore wall pressure release outside, prevent aggregate from running leakage, serosity (aggregate, water
Mud) first after penetrating into closure roadway floor water outlet crack passage at casing failure, and then it is solid to enter filling between inner and outer pipe
Pipe, then plugging water-bearing stratum, it is achieved filling between roadway floor water blockoff and inner and outer pipes, with reach inner and outer pipe admittedly manage and realize right
The purpose of the improvement of borehole sealing and roadway floor water outlet.
