Abstract
A water burst blast hole plugging method comprises the steps of (1) stopping drilling instantly and withdrawing a drill rod when water burst occurs during blast hole drilling; (2) ejecting a high-pressure rubber expansion rubber hose into the bottom of a hole with a drilling machine, wherein the two ends of the high-pressure rubber expansion rubber hose are sealed, and a check valve and a water injection rubber hose are installed at one end of the high-pressure rubber expansion rubber hose; (3) injecting pressure water into the high-pressure rubber expansion rubber hose with a high-pressure pump by means of the water injection rubber hose to enable the high-pressure rubber expansion rubber hose to be large enough to abut against the blast hole; (4) withdrawing the drilling rod; (5) conducting grout sealing on the blast hole; (6) stop grouting after the blast hole is filled with grout. The method well achieves hole plugging when water burst occurs during blast hole drilling which is conducted in an area with abundant underground water and is highly targeted, the high-pressure rubber expansion rubber hose is expanded after reaching the bottom of the hole, water burst is prevented from being continued through the blast hole, the portion, between the high-pressure rubber expansion rubber hose and the opening of the blast hole, of the blast hole does not contain gush water any more, cement mortar grout sealing can be conducted on the blast hole conveniently, sealing is easy and convenient, construction speed is high, quality is high, grout loss is avoided, plugging effect is good, and cost is low.
Description
Technical field
The present invention relates in the process of a kind of blasthole drilling hole shutoff method when there is water burst, particularly relating to a kind of for being the positions such as river, lake, reservoir outside rich groundwater area or country rock, in the boring procedure in big gun hole, occurring shutoff method during water burst.
Background technology
Time outside rich groundwater area or country rock for carrying out explosion in the position such as river, lake, reservoir big gun hole used drilling construction process in, once blasthole drilling is to pervious layer or be drilled in river outside country rock, lake, reservoir through rock stratum, the water of underground water or river, lake, reservoir can be gushed out from big gun hole, cause follow-up construction normally to carry out, must block the big gun hole of water burst.The obstruction method of current routine utilizes stopper or grouting embolism to carry out shutoff, because the press water in hole exists, the aperture in water burst big gun hole can only be blocked, then pressure grouting is carried out in perforate aside, due to the river in water burst big gun hole and underground water passage or outside, lake, reservoir communicates, cause water burst multiple-row blasting difficulty, it is large that slurries fill up water burst big gun hole difficulty, the plug-hole time is long, slurry stream vector is also larger, difficult quality guarantee after blocking, blocking weak effect, costly, and once blocking poor quality, the Forming Quality in other big gun hole near also directly affecting, thus affect the powder charge in big gun hole and the demolition effect of rock, and cause the significantly increase of expense.
Summary of the invention
For above-mentioned deficiency or problem, the invention provides a kind of shutoff method for water burst big gun hole, solving preferably outside rich groundwater area or country rock is water blockoff problem when water burst appears in the position such as river, lake, reservoir in the boring procedure in big gun hole.
The taked technical measures that solve the problem are:
For the shutoff method in water burst big gun hole, it is characterized in that:
(1) when blasthole drilling hole runs into water burst situation, stop immediately creeping into, opposite spin, exits drilling rod;
(2) rig being drilled with big gun hole is utilized to head in hole by high pressure rubber Dilated rubber hose, stop after at the bottom of jacking always to hole, make high pressure rubber Dilated rubber hose be arranged on position at the bottom of hole, high pressure rubber Dilated rubber hose two ends are enclosed construction, and at one end install a non retern valve and water filling sebific duct;
(3) utilize the water filling sebific duct that high pressure rubber Dilated rubber hose one end is installed, adopt high-pressure pump to injection pressure water in high pressure rubber Dilated rubber hose, make it volume expansion, until swelling big gun hole, be securely fixed in big gun hole;
(4) exit the drilling rod of rig, now water burst is no longer poured in by big gun hole, no longer includes water burst and exist in the big gun hole between high pressure rubber Dilated rubber hose to aperture, big gun hole;
(5) bore hole-top-enclosed grouting method is adopted this big gun hole to be carried out to the grout sealing of cement mortar;
(6) slurries of cement mortar stop grouting after filling up big gun hole, and after grout cures, the shutoff of big gun hole is complete.
beneficial effect of the present invention: the present invention solves the water blockoff problem in water burst big gun hole preferably, because the method is with strong points, adopting this technology to enrich outside area or country rock underground water is river, lake, water blockoff is carried out when water burst appears in the positions such as reservoir in the boring procedure in big gun hole, swelling again after at the bottom of hole is arrived under high pressure rubber Dilated rubber hose, water burst is no longer poured in by big gun hole, no longer include water burst in big gun hole between high pressure rubber Dilated rubber hose to aperture, big gun hole to exist, the cement mortar grouting shutoff in big gun hole can be carried out so easily, plugging construction is simple and convenient, speed of application is fast, quality is high, and there is not the loss of slurries, block effective, low cost, water burst big gun hole after can fully ensureing shutoff can not have a negative impact to other bore operation.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
For the shutoff method in water burst big gun hole, the steps include:
(1) when blasthole drilling hole runs into water burst situation, stop immediately creeping into, operation rig, makes drilling rod opposite spin, progressively exits drilling rod.
(2) get out high pressure rubber Dilated rubber hose, high pressure rubber Dilated rubber hose length is 30 ~ 50cm, external diameter 3 ~ 5mm less of blasthole diameter, wall thickness 8 ~ 10mm.High pressure rubber Dilated rubber hose two ends are enclosed construction, and at one end a non retern valve and water filling sebific duct are installed, high pressure rubber Dilated rubber hose is arranged on the front end of drilling rod, utilize the rig being drilled with big gun hole, driven by drilling rod, high pressure rubber Dilated rubber hose is headed in hole, stops after at the bottom of jacking always to hole, make high pressure rubber Dilated rubber hose be 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, adopt high-pressure pump to pass through water filling sebific duct to injection pressure water in high pressure rubber Dilated rubber hose, make it volume expansion, until swelling big gun hole, be securely fixed in big gun hole.
(4) operate rig, make drilling rod opposite spin, exit the drilling rod of rig, now water burst is no longer poured in by big gun hole, no longer includes water burst and exist in the big gun hole between high pressure rubber Dilated rubber hose to aperture, big gun hole.
(5) bore hole-top-enclosed grouting method is adopted to carry out the grout sealing of cement mortar to this big gun hole, the match ratio of cement mortar is: cement: sand: water=1: 1: 0.5, cement employing label is the Portland cement of 32.5 or 42.5, sand adopt fineness modulus be 1.6 ~ 3.0 medium sand or fine sand, and in slurries the water glass of admixture cement consumption 3% ~ 10%.
(6) slurries of cement mortar stop grouting after filling up big gun hole, and after grout cures, the shutoff of big gun hole is complete.
After the hole shutoff of water burst big gun, other bore operation can be carried out in its vicinity.The method blocking is effective, and reliable in quality, simple, expense is low, and the water burst big gun hole after can fully ensureing shutoff can not have a negative impact to other bore operation.
