Abstract
The invention relates to a construction method for controlling drilling positions to penetrate through guide rock strata. The method comprises: 1) drilling: determining a hole opening point through surveying and setting out, and operating a drilling machine for hole opening and drilling; 2) hole deviation measuring: using a clinometers for measuring the deviation to master the guide hole deviation degree timely in a guide hole drilling process; 3) hole bottom blasting: using hole bottom blasting to damage the rock stratum direction when deviation and guide rock strata occur in the drilling process; 4) consolidation grouting: performing cement grouting on the hole bottom to consolidate blasting gaps and rock masses into a whole; and 5) repeated drilling, hole bottom blasting, consolidation grouting and drilling: continuing to perform drilling, hole bottom blasting, dense slurry consolidation grouting, coagulation and drilling again, and repeating the steps for a plurality of times till the guide rock strata are penetrated smoothly and accurately. The construction method is simple and convenient, the speed is fast, and the drilling position can be controlled effectively to penetrate through the guide rock strata.
Description
Technical field:
The present invention relates to the method in a kind of keyhole orientation, in particular a kind of job practices of passing through guiding CONTROL OF STRATA MOVEMENT bore direction.
Background technology:
In water conservancy project, the vertical shaft of the object of construction production such as mining industry is particularly in the deep shaft excavation construction, because rock geology complicated condition, tend to run into " guiding " rock stratum, these " guiding " rock stratum generally is the steep dip rock stratum of comparison hard, direction and the strike angle of guiding are larger, these guiding rock stratum can have certain guide effect to boring direction in the guide hole drilling process, the hole scattering direction all tilts to same direction, the whole hole deviation proportion that can cause holing all far exceeds the guide hole required precision becomes useless hole, adopt also uncontrollable its deviation proportion of conventional satisfactory after correcting such as " fill concretes; the middle part adds stabiliser bar; the levelness of controlled drilling rate and rig ", have a strong impact on speed of application and construction quality.
Summary of the invention:
The present invention seeks in order to overcome upper deficiency, provide a kind of construction technology simple, convenient, speed is fast, passes through safely and fast steep dip guiding rock stratum, and the job practices in the keyhole orientation of guiding rock stratum is passed through in the keyhole orientation effectively.
The object of the present invention is achieved like this:
The present invention passes through the job practices of guiding CONTROL OF STRATA MOVEMENT bore direction, and the method may further comprise the steps:
1) creeps into: determine tapping point by measuring unwrapping wire, accurately set up perforation of boring machine and creep into;
2) hole deviation is measured: in the pilot hole drilling process, regularly adopt the inclinometer deviational survey, in time grasp the pilot hole drift rate, unusual circumstance takes measures to control, diligent deviational survey;
3) explosion at the bottom of the hole: if deflection occurs in drilling process, run into the guiding rock stratum, take explosion at the bottom of the hole, destroy its strike, blasting parameter is determined by explosion bulge test according to rocky condition;
4) consolidation grouting: after the explosion, to carrying out cementation at the bottom of the hole blasting crack and sillar are consolidated into integral body at the bottom of the hole, bit force is consistent when guaranteeing again to creep into, and guarantees correct drilling direction;
5) repeatedly creep into, explosion, consolidation grouting at the bottom of the hole, creep into: cementation is wait continuing to creep into behind the bundle that condenses, explosion, underflow consolidation grouting at the bottom of the hole, waiting to coagulate, creep into, repeatedly repeatedly until successfully accurately pass through the guiding rock stratum.
Above-mentioned step 2) situation of undergoing an unusual development takes to add stable drilling rod, control rate of penetration, control rig levelness in.
In drilling process, occur in the above-mentioned step 3) deflection take to add stable drilling rod, control rate of penetration, control rig levelness control can not control deflection and run into the guiding rock stratum and then take the hole at the bottom of explosion destroy strike.
Said method admixture water reducing agent, early strength admixture in filling process are treated the solidifying time to improve concentration of slurry, to improve the slurries early strength, to reduce.
The inventive method is to run into the guiding rock stratum in vertical shaft pilot hole drilling process, destroy attitude of rocks by the explosion means and lose guide effect, carry out cementation and be consolidated into integral body through explosion sillar and explosion being split battle array again, make in its drilling process drilling tool stressed evenly, thereby realized effective control pilot hole bore direction, guaranteed the drilling construction quality of pilot hole, and construction technology is simple, handling safety, speed of application are fast.
Description of drawings:
Fig. 1 is that the present invention passes through guiding CONTROL OF STRATA MOVEMENT bore direction construction schematic diagram.
Fig. 2 is explosion schematic diagram at the bottom of the hole.
Fig. 3 is the consolidation grouting schematic diagram.
The specific embodiment:
The present embodiment passes through the job practices of guiding CONTROL OF STRATA MOVEMENT bore direction, may further comprise the steps:
1, creeps into: referring to Fig. 1, determine the pilot hole tapping point by measuring unwrapping wire, accurately set up rig 1 perforate and creep into;
2, hole deviation is measured: referring to Fig. 1, in pilot hole 2 drilling processes, regularly adopt the inclinometer deviational survey, in time grasp pilot hole 2 drift rates, unusual circumstance is taked to add the measures such as stable drilling rod, control rate of penetration, control rig levelness and is controlled diligent deviational survey;
3, explosion at the bottom of the hole: referring to Fig. 1, Fig. 2, if deflection in drilling process, occurs, take also uncontrollable its deviation proportion and when tilting to same direction of satisfactory after correcting such as levelness that fill concrete, middle part add stabiliser bar, controlled drilling rate and rig, illustrate and run into guiding rock stratum 3, take explosion 4 at the bottom of the hole this moment, destroy the strike of its guiding rock stratum 3, blasting parameter is determined by explosion bulge test according to rocky condition;
4, consolidation grouting: referring to Fig. 3, after the explosion, to carrying out cementation at the bottom of the hole blasting crack and sillar are consolidated into integral body 5 at the bottom of the hole, bit force is consistent when guaranteeing again to creep into, and guarantees correct drilling direction.Admixture water reducing agent, early strength admixture are treated the solidifying time to improve concentration of slurry, to improve the slurries early strength, to reduce in filling process;
5, repeatedly creep into, explosion, consolidation grouting at the bottom of the hole, creep into: cementation wait continue to creep into behind the bundle that condenses, hole deviation is measured, explosion 4, underflow consolidation grouting 5 at the bottom of the hole, wait to coagulate, creep into, repeatedly repeatedly until successfully accurately pass through the guiding rock stratum;
The a large amount of creative evidences of process: construction technology of the present invention is simple, handling safety, and speed of application is fast, has realized effective control pilot hole bore direction, has guaranteed the drilling construction quality of pilot hole.
Above-described embodiment is that foregoing of the present invention is further described, but this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to above-described embodiment.All technology that realizes based on foregoing all belong to scope of the present invention.
