Abstract
The invention discloses a plugging device for a water-inrush borehole by filtration flow and pressure relief of a hole wall and grouting and fixing of an in-hole bushing. The plugging device comprises an orifice outer tube and the in-hole bushing both stretching into a roadway bottom plate, and a gap is formed between the orifice outer tube and the in-hole bushing; a staggered fracture position is formed at the lower part of the orifice outer tube; a hole wall filtration flow and pressure relief unit is mounted at the upper end of the orifice outer tube, and comprises a filtering screen mounted in a hole wall pressure relief position; a pressure relief valve is mounted outside the filtering screen; an orifice gate valve is mounted at the upper end of the hole wall filtration flow and pressure relief unit; a material tube is connected to the upper end of the orifice gate valve, and an orifice grout inlet valve is mounted at the upper end of the material tube. The plugging device solves the problem that the borehole cannot be plugged because a large amount of slurry gushes out of water-inrush positions in the bottom plate at the shallow part of the roadway on the periphery when a conventional orifice direct grouting method is used for the condition that a large amount of water in the hole gushes out of the bottom plate at the shallow part of the roadway on the periphery for pressure relief.
Description
Technical field
The present invention relates to bored grouting plugging technology, particularly belong to the gushing water borehole wall filter solid pipe plugging device of stream pressure relief vent inner sleeve slip casting.
Background technology
The underground for probing drilling construction that discharges water is that complicated hydrogeological conditions mine water disaster administers conventional measure, but often occur owing to water-bearing layer hydraulic pressure is high, mine crustal stress is big, boring base plate lithology is poor, drill admittedly be not in control the underground for probing that the factor such as position or casing corrosion causes discharge water borehole casing break, bad break, in hole, big flow, water under high pressure bad break sleeve pipe place and the conducting of superficial part crack, tunnel, 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 cost of mine.This type of accident treatment must block water outlet boring in time, owing in hole, the water yield pours out pressure release through periphery tunnel superficial part base plate, when using the direct slip casting method in conventional aperture, serosity pours out from casing-broken and tunnel superficial part Water Inrush point, cause boring to block, be badly in need of a kind of new solid pipe, slip casting plugging technology.
Summary of the invention
It is an object of the invention to provide a kind of gushing water borehole wall filter solid pipe plugging device of stream pressure relief vent inner sleeve slip casting, solve in hole the water yield to pour out pressure release through periphery tunnel superficial part base plate, when using the direct slip casting method in conventional aperture, serosity pours out from through periphery tunnel superficial part Water Inrush point, causes the difficult problem that boring cannot block.
Technical scheme is as follows:
A kind of gushing water borehole wall filter solid pipe plugging device of stream pressure relief vent inner sleeve slip casting, include the aperture outer tube, the hole inner sleeve that stretch in roadway floor, between aperture outer tube and hole inner sleeve, there is gap, outer tube bottom, aperture has bad break place, outer tube upper end, aperture is provided with hole wall filter stream pressure relief device, hole wall filter stream pressure relief device includes the drainage screen that hole wall pressure release place is installed, relief valve is installed outside drainage screen, hole wall filter stream pressure relief device upper end is provided with aperture gate valve, gate valve upper end, aperture is connected to material pipe, and material pipe upper end is provided with aperture slurry-inlet valve.
Described serosity first penetrates into after the passage of closure roadway floor water outlet crack through hole inner sleeve breaking part, enter the clearance filled solid pipe between aperture outer tube, hole inner sleeve, plugging water-bearing stratum again, realizing filling between roadway floor water blockoff and aperture outer tube, hole inner sleeve, to realize aperture outer tube, hole inner sleeve admittedly manages and realizes the improvement to borehole sealing and roadway floor water outlet.
The present invention realizes " stitching " filling between roadway floor water blockoff and inner and outer pipes, admittedly manages and realizes the purpose to borehole sealing and the improvement of roadway floor water outlet reaching interior pipe.Solving in hole the water yield to pour out pressure release through periphery tunnel superficial part base plate, when using the direct slip casting method in conventional aperture, serosity pours out from through periphery tunnel superficial part Water Inrush point, causes the difficult problem that boring cannot block.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Referring to accompanying drawing, a kind of gushing water borehole wall filter solid pipe plugging device of stream pressure relief vent inner sleeve slip casting, include the aperture outer tube 7 stretched in roadway floor 10, hole inner sleeve 8, between aperture outer tube 7 and hole inner sleeve 8, there is gap, aperture outer tube 7 bottom has bad break place 9, aperture outer tube 7 upper end is provided with hole wall filter stream pressure relief device 6, hole wall filter stream pressure relief device 6 includes the drainage screen 5 that hole wall pressure release place is installed, relief valve 4 is installed outside drainage screen 5, hole wall filter stream pressure relief device 6 upper end is provided with aperture gate valve 3, aperture gate valve 3 upper end is connected to material pipe 2, material pipe 2 upper end is provided with aperture slurry-inlet valve 1.
Serosity first penetrates into after the passage of closure roadway floor water outlet crack through hole inner sleeve breaking part, enter the clearance filled solid pipe between aperture outer tube, hole inner sleeve, plugging water-bearing stratum again, realizing filling between roadway floor water blockoff and aperture outer tube, hole inner sleeve, to realize aperture outer tube, hole inner sleeve admittedly manages and realizes the improvement to borehole sealing and roadway floor water outlet.
The technical process of the present invention:
1, the present invention enters small-diameter hole inner sleeve to casing-broken place under in the outer tube of aperture, slip casting (aggregate, cement mortar) in Guan Xiangkong in utilizing, it is to avoid during the outer tube slip casting of aperture, serosity runs in a large number Lou, gushes out.
2, pore mouth is installed hole wall worry and is flowed pressure device outside, and filter screen is installed in hole wall pressure release place additional, it is prevented that aggregate runs leakage.
3, serosity (aggregate, cement mortar) penetrates into closure roadway floor water outlet crack passage through casing failure place, it is achieved the improvement to base plate water outlet.
4, serosity (aggregate, cement mortar) enters filling between inner and outer pipe, it is achieved " stitching " filling and solid pipe purpose between boring inner and outer pipes.
5, pipe slip casting plugging water-bearing stratum in utilization, solves the difficult problem using the direct slip casting method boring in conventional aperture to block, it is achieved the purpose to borehole sealing and the improvement of roadway floor water outlet.
