Description
Technical field
Shutoff method during retention of excessive fluid occurs during the present invention relates to a kind of blasthole drilling hole, particularly relates to a kind of for underground
It is the positions such as river, lake, reservoir outside the abundant area of water or country rock, the boring procedure in big gun hole occurs water blockoff during retention of excessive fluid
Method.
Background technology
It is that the positions such as river, lake, reservoir carry out big gun hole used during explosion outside rich groundwater area or country rock
During drilling construction, once blasthole drilling is drilled in the river outside country rock, lake, reservoir to pervious bed or through rock stratum,
Subsoil water or river, lake, the water of reservoir can be gushed out from big gun hole, cause follow-up construction to be normally carried out, it is necessary to gushing
The big gun hole of water blocks.The most conventional obstruction method is to utilize stopper or grouting thromboembolism to block, due in hole
Press water exist, the aperture in retention of excessive fluid big gun hole can only be blocked, perforate the most aside carries out pressure grouting, due to retention of excessive fluid big gun hole with
Subsoil water passage or the river in outside, lake, reservoir communicate, and cause retention of excessive fluid multiple-row blasting difficulty, and serosity fills up retention of excessive fluid big gun
Hole difficulty is big, and the plug-hole time is long, and slurry stream vector is the biggest, and the difficult quality guarantee after blocking blocks weak effect, and expense is relatively
Height, and once block poor quality, also directly affect near the Forming Quality in other big gun hole, thus affect big gun hole powder charge and
The demolition effect of rock, and cause being significantly increased of expense.
Summary of the invention
For above-mentioned deficiency or problem, the invention provides a kind of shutoff method for retention of excessive fluid big gun hole, preferably solve
When retention of excessive fluid occurring for positions such as river, lake, reservoirs in the boring procedure in big gun hole outside rich groundwater area or country rock
Water blockoff problem.
The technical measures that solution the problems referred to above are taked are:
A kind of shutoff method for retention of excessive fluid big gun hole, it is characterised in that:
(1) when blasthole drilling hole runs into retention of excessive fluid situation, stopping immediately creeping into, opposite direction rotates, and exits drilling rod；
(2) getting out high pressure rubber Dilated rubber hose, high pressure rubber Dilated rubber hose two ends are enclosed construction, and at one end install
One non-return valve and water filling sebific duct, be arranged on the front end of drilling rod by high pressure rubber Dilated rubber hose, utilizes the rig being drilled with big gun hole, logical
Crossing drilling rod to drive, head in hole by high pressure rubber Dilated rubber hose, jacking always stops after at the bottom of hole, makes high pressure rubber Dilated rubber hose
It is arranged on position at the bottom of hole；
(3) utilize the water filling sebific duct that high pressure rubber Dilated rubber hose one end is installed, use high-pressure pump to high pressure rubber expansion glue
Injection pressure water in pipe, is allowed to volumetric expansion, until swelling big gun hole, is securely fixed in big gun hole；
(4) exiting the drilling rod of rig, now retention of excessive fluid is no longer poured in by big gun hole, and high pressure rubber Dilated rubber hose is to aperture, big gun hole
Between big gun hole in no longer with the presence of retention of excessive fluid；
(5) use bore hole-top-enclosed grouting method that this big gun hole carries out the grout sealing of cement mortar；
(6) stopping grouting after the serosity of cement mortar fills up big gun hole, after grout cures, the closure of big gun hole is complete.
Beneficial effects of the present invention: the present invention preferably solves the water blockoff problem in retention of excessive fluid big gun hole, due to the method for
Property strong, use outside this technology area abundant to subsoil water or country rock as position borings in big gun hole such as river, lake, reservoirs
Carrying out during retention of excessive fluid occurs water blockoff in journey, swelling again after arriving at the bottom of hole under high pressure rubber Dilated rubber hose, make retention of excessive fluid no longer be gushed by big gun hole
Enter, no longer with the presence of retention of excessive fluid in the big gun hole between high pressure rubber Dilated rubber hose to aperture, big gun hole, so can carry out easily
The cement mortar grouting closure in big gun hole, plugging construction is simple and convenient, speed of application is fast, and quality is high, and there is not the loss of serosity,
Block effective, low cost, can fully ensure that the retention of excessive fluid big gun hole after closure will not produce unfavorable shadow to other bore operation
Ring.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
A kind of shutoff method for retention of excessive fluid big gun hole, the steps include:
(1) when blasthole drilling hole runs into retention of excessive fluid situation, stop immediately creeping into, operate rig, make drilling rod opposite direction rotate, by
Step exits drilling rod.
(2) getting out high pressure rubber Dilated rubber hose, high pressure rubber Dilated rubber hose a length of 30～50cm, external diameter is than big gun hole
Diameter little 3～5mm, wall thickness 8～10mm.High pressure rubber Dilated rubber hose two ends are enclosed construction, and at one end install a check
Valve and water filling sebific duct, be arranged on the front end of drilling rod by high pressure rubber Dilated rubber hose, utilizes the rig being drilled with big gun hole, by drilling rod band
Dynamic, high pressure rubber Dilated rubber hose is headed in hole, jacking always stops after at the bottom of hole, makes high pressure rubber Dilated rubber hose be arranged on hole
Position, the end.
(3) utilize the water filling sebific duct that high pressure rubber Dilated rubber hose one end is installed, use high-pressure pump by water filling sebific duct to height
Injection pressure water in pressure rubber swelling sebific duct, is allowed to volumetric expansion, until swelling big gun hole, is securely fixed in big gun hole.

High pressure rubber Dilated rubber hose in the big gun hole between aperture, big gun hole no longer with the presence of retention of excessive fluid.
(5) bore hole-top-enclosed grouting method is used to carry out the grout sealing of cement mortar, the match ratio of cement mortar in this big gun hole
For: cement: sand: water=1: 1: 0.5, cement uses the Portland cement being numbered 32.5 or 42.5, and sand uses fineness
Modulus is medium sand or the fine sand of 1.6～3.0, and fills the waterglass of cement consumption 3%～10% in serosity.
(6) stopping grouting after the serosity of cement mortar fills up big gun hole, after grout cures, the closure of big gun hole is complete.
After the closure of retention of excessive fluid big gun hole, other bore operation can be carried out in its vicinity.The method blocking is effective, quality
Reliably, simple, expense is low, can fully ensure that the retention of excessive fluid big gun hole after closure will not produce unfavorable shadow to other bore operation
Ring.
