Abstract
The present invention is the construction method of passing through guiding CONTROL OF STRATA MOVEMENT bore direction, comprising: 1) creep into: by surveying setting-out determination tapping point, and accurately erection perforation of boring machine creeps into; 2) hole deviation is measured: in pilot hole drilling process, regularly adopts inclinometer deviational survey, grasps pilot hole drift rate in time; 3) explosion at the bottom of hole: occur deflection in drilling process, run into guiding rock stratum, take explosion at the bottom of hole, destroy its strike; 4) consolidation grouting: after explosion at the bottom of hole, is consolidated into entirety to carrying out cementation at the bottom of hole by blasting crack and sillar; 5) repeatedly creep into, explosion, consolidation grouting at the bottom of hole, to creep into: cementation continues to creep into after condensation bundle, explosion, underflow consolidation grouting at the bottom of hole, wait to coagulate, creep into, repeatedly repeatedly until successfully accurately pass through guiding rock stratum.The inventive method is simple, convenient, and speed is fast, effectively can pass through guiding rock stratum in keyhole orientation.
Description
technical field:
The present invention relates to a kind of method of keyhole orientation, in particular a kind of construction method 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 deep shaft excavation construction, due to rock geology complicated condition, often run into " guiding " rock stratum, these " guiding " rock stratum is generally the steep dip rock stratum of comparing hard, direction and the strike angle of guiding are larger, these guiding rock stratum can have certain guide effect to boring direction in guide hole drilling process, hole scattering direction all tilts to same direction, the whole hole deviation proportion that can cause holing all far exceeds guide hole required precision becomes useless hole, adopt conventional " fill concrete, middle part adds stabiliser bar, the levelness of controlled drilling rate and rig " etc. satisfactory after correcting also its deviation proportion uncontrollable, have a strong impact on speed of application and construction quality.
summary of the invention:
The present invention seeks to overcome upper deficiency, provide a kind of construction technology simple, convenient, speed is fast, passes through steep dip guiding rock stratum safely and fast, effectively can pass through the construction method in the keyhole orientation of guiding rock stratum in keyhole orientation.
The object of the present invention is achieved like this:
The present invention passes through the construction method of guiding CONTROL OF STRATA MOVEMENT bore direction, and the method comprises the following steps:
1) creep into: by surveying setting-out determination tapping point, accurately erection perforation of boring machine creeps into;
2) hole deviation is measured: in pilot hole drilling process, and regularly adopt inclinometer deviational survey, grasp pilot hole drift rate in time, unusual circumstance takes measures to control, diligent deviational survey;
3) explosion at the bottom of hole: if there is deflection in drilling process, run into guiding rock stratum, take explosion at the bottom of hole, destroy its strike, blasting parameter is determined by explosion bulge test according to rocky condition;
4) consolidation grouting: after explosion at the bottom of hole, is consolidated into entirety to carrying out cementation at the bottom of hole by blasting crack and sillar, and when guaranteeing again to creep into, bit force is consistent, ensures correct drilling direction;
5) repeatedly creep into, explosion, consolidation grouting at the bottom of hole, to creep into: cementation continues to creep into after condensation bundle, explosion, underflow consolidation grouting at the bottom of hole, wait to coagulate, creep into, repeatedly repeatedly until successfully accurately pass through guiding rock stratum.
Above-mentioned step 2) in the situation of undergoing an unusual development take to add stable drilling rod, control rate of penetration, control rig levelness.
In drilling process, occur in above-mentioned step 3) that deflection is taked to add stable drilling rod, controls rate of penetration, controlled rig levelness and carry out control and can not control deflection and run into guiding rock stratum and then take explosion at the bottom of hole to destroy strike.
Said method admixture water reducing agent, early strength admixture in filling process, to improve concentration of slurry, to improve slurries early strength, reduce and treat the solidifying time.
The inventive method is in vertical shaft pilot hole drilling process, run into guiding rock stratum, destroy attitude of rocks by explosion means and lose guide effect, carry out cementation be consolidated into entirety through splitting battle array to explosion sillar and explosion again, make drilling tool uniform force in its drilling process, thus achieve effectively control pilot hole bore direction, ensure that the drilling construction quality of pilot hole, and construction technology is simple, handling safety, speed of application are fast.
accompanying drawing illustrates:
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 hole.
Fig. 3 is consolidation grouting schematic diagram.
detailed description of the invention:
The present embodiment passes through the construction method of guiding CONTROL OF STRATA MOVEMENT bore direction, comprises the following steps:
1, creep into: see Fig. 1, by surveying setting-out determination pilot hole tapping point, accurately the perforate of erection rig 1 is crept into;
2, hole deviation is measured: see Fig. 1, in pilot hole 2 drilling process, regularly adopt inclinometer deviational survey, grasp pilot hole 2 drift rate in time, 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 hole: see Fig. 1, Fig. 2, if there is deflection in drilling process, take fill concrete, middle part add stabiliser bar, the satisfactory after correcting such as the levelness of controlled drilling rate and rig also its deviation proportion uncontrollable and tilt to same direction time, explanation runs into guiding rock stratum 3, now take explosion 4 at the bottom of hole, destroy the strike of its guiding rock stratum 3, blasting parameter is determined by explosion bulge test according to rocky condition;
4, consolidation grouting: see Fig. 3, after explosion at the bottom of hole, to carrying out cementation at the bottom of hole, blasting crack and sillar are consolidated into overall 5, when guaranteeing again to creep into, bit force is consistent, ensures correct drilling direction.In filling process, admixture water reducing agent, early strength admixture are to improve concentration of slurry, to improve slurries early strength, reduce and treat the solidifying time;
5, repeatedly creep into, explosion, consolidation grouting at the bottom of hole, to creep into: cementation continues to creep into after condensation bundle, hole deviation is measured, explosion 4, underflow consolidation grouting 5 at the bottom of hole, wait to coagulate, creep into, repeatedly repeatedly until successfully accurately pass through guiding rock stratum;
Prove through a large amount of creative test: construction technology of the present invention is simple, handling safety, and speed of application is fast, achieves and effectively controls pilot hole bore direction, ensure that the drilling construction quality of pilot hole.
Above-described embodiment is further described foregoing of the present invention, but this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to above-described embodiment.All technology realized based on foregoing all belong to scope of the present invention.
