Abstract
The invention discloses a water detection borehole bottom insertion pipe grouting method. The water detection borehole bottom insertion pipe grouting method includes: firstly, penetrating a grouting pipe into a borehole, and then injecting cement grout into the borehole through a grouting pipe orifice, withdrawing a segment of the grouting pipe, 30m in length, after each barrel of cement slurry is injected into the borehole, welding a stop valve blocking disk on a seal pipe after the grouting pipe is completely withdrawn, continuing to inject another barrel of the cement slurry into the borehole, closing a stop valve, dismantling the grouting pipe, washing a grouting pump, and completing grouting. A water-cement mass ratio of the cement grout is 1:2. Preferably, the grouting pipe is a galvanized DN15 iron pipe 3m in length, screw threads for connection sleeves are arranged at two ends of the grouting pipe, and a proportion of the length of the grouting pipe penetrated into the borehole to the length of the borehole is 80%-90%. The water detection borehole bottom insertion pipe grouting method achieves the purpose of discharging accumulated water and gas in the borehole out during the grouting process, and simultaneously performs the grouting under the condition that no pressure is applied, and furthermore improves grouting hole sealing effects.
Description
Technical field
The present invention relates to a kind of slip casting method, specifically, is intubate slip casting method at the bottom of hole, a kind of water exploring drill hole.
Background technology
The hole sealing technology adopted both at home and abroad at present mainly contains mechanic water injection cement mortar sealing of hole, foaming polymeric materials sealing of hole, hole packer sealing of hole etc.Wherein, cement mortar sealing of hole is mainly applicable to inclined drill, for nearly level or gently inclined seam then inapplicable; Foaming polymeric materials sealing of hole has that coefficient of foaming is high, sealing of hole advantage efficiently, but its sealing material cost is high; Rapid hole packer sealing of hole speed is fast, reusablely reduces costs, but sealing of hole section is short, weak effect, is only applicable to interim extraction sealing of hole.On the whole, existing method for sealing is only limited to and how " blocks up "
Boring, and do not relate to how shutoff and process cracks in coal seam and gas leakage, due to the agensis of coal seam floor formation pore crazing gap, the present situation that gas density is high, needs hole internal water accumulation and gas to be discharged in slip casting process, could improve the effect of injection hole sealing.
Summary of the invention
The invention solves the deficiencies in the prior art, provide intubate slip casting method at the bottom of hole, a kind of water exploring drill hole.
In order to achieve the above object, the technical solution adopted in the present invention is:
Intubate slip casting method at the bottom of a kind of hole, water exploring drill hole, be in first Grouting Pipe deeply being holed, then injecting water ash mass ratio from the slip casting mouth of pipe is the cement grout of 1:2, often note one barrel of cement paste, withdraw from 30 meters of Grouting Pipe, after Grouting Pipe is all withdrawn from, sealing tube is welded with the stifled dish of stop valve, continues cement injection one barrel in hole, close stop valve, dismantle grouting pipeline, cleaning grouting pump, slip casting is complete.
Preferably, described Grouting Pipe is zinc-plated 4 points of iron pipes, length 3 meters, and two ends are provided with the screw thread of adapter sleeve; The ratio of the described length and drillable length of going deep into Grouting Pipe is 80%-90%.
The present invention utilizes intubate hole-bottom slurry-injection the water in hole and gas can be discharged in advance, and cement paste injection rate improves 0.6 cubic metre by original 0.24 cubic metre, and grouting amount improves 2.5 times.Slurries can effectively be filled in hole, enhance slip casting difficulty action accomplishment; Originally the grouting method of employing needs the pressure of 2-3MPa, and needed for new grouting method, grouting pressure is at about 1MPa, and grouting pressure reduces to avoid orifice tube and rubber cushion to burst out, and causes mud to spray and damages personnel; Intubate slip casting at the bottom of hole can inject cement quality than higher mud, and separate out the water yield after theing cement solidifies less, cement effectively can fill boring.
