Description

A kind of rotary drilling rig ground consisting of hard rock classification drilling construction technique
Technical field
The present invention relates to a kind of drilling construction technique, specifically a kind of rotary drilling rig ground consisting of hard rock classification drilling construction technique.
Background technology
Current rotary drilling rig, when ground consisting of hard rock creeps into, uses traditional drilling assembly construction technology mostly, namely first uses cylinder to creep into, then uses augers broken, finally use Double-bottom-plate to drag for slag; This kind of construction technology, drilling efficiency is lower, and pick consumption is larger.Also part building site is had at present, classification drilling construction technique is adopted to creep into, but mostly exist hierarchical approaches confusion, can not the problem such as reasonable employment drill bit, the operating process not having specification, cause drill bit unreasonable allocation in early stage, creep in frequently change working procedure in drill bit, construction chaotic, effectively drilling time cannot to ensure etc. problem to cause the advantage of classification drilling construction technique to play.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of rotary drilling rig ground consisting of hard rock classification drilling construction technique, by rational classification, carry out multiple fractionation reaming and creep into, can effectively increase work efficiency.
To achieve these goals, the technical solution used in the present invention is: a kind of rotary drilling rig ground consisting of hard rock classification drilling construction technique, and concrete steps are:
A. first use bore diameter to creep into row rock stratum at the small-bore cylindrical rock of 800mm-1000mm to creep into, then drag for sand hopper by bore diameter in the small-bore of 800mm-1000mm and carry out scarfing cinder, so repeatedly coordinate and creep into required stake holes degree of depth h;
B. according to the diameter that the diameter of required stake holes and the cylindrical rock of holing first bore, determine the progression of classification reaming, make diameter difference between adjacent holes within the scope of 400mm-500mm;
C. the reaming cylindrical rock of bore diameter one-level larger than step a is used to creep into row ream operation, cutting the many rubbles got off in reaming procedure can fall in the hole that aperture creeps into, according to the rubble earthwork that earthwork in aperture and reaming cut, calculate the macropore counterbore depth H when aperture space is filled up, concrete design formulas is:
H = π ( d / 2 ) 2 h π ( ( D / 2 ) 2 - ( d / 2 ) 2 )
H in formula is counterbore depth; D is counter bore diameter; H is the stake holes degree of depth; D is small-bore diameter; When arriving counterbore depth H, stop reaming;
D. after stopping reaming, use small-bore to drag for sand hopper and carry out scarfing cinder, and then use the large aperture cylindrical rock in step c to bore continuation reaming, then scarfing cinder, iterative cycles is until creep into required stake holes degree of depth h;
E. bore and drag for sand hopper with the reaming cylindrical rock of the large one-level of the bore diameter used than previous step and repeat step c, d, the hole reaming formed previous step, scarfing cinder, until counter bore diameter reaches the diameter of required stake holes, drilling depth reaches required stake holes degree of depth h;
F. as needed the progression of classification reaming to equal two-stage, then without the need to step e; As needed the progression of classification reaming to be greater than three grades, then corresponding repetition step e.
Compared with prior art, the method that the present invention adopts classification to creep into, ensures smoothness, the Effec-tive Function of working procedure, improves drilling efficiency, efficiency of construction can be improved 1.5 times, cylindrical rock is used to bore when reaming is crept into, avoid when using Double-bottom-plate reaming to creep into, heel teeth is stressed, center is unsettled, the problem of drill bit rapid wear, and use cylindrical rock to bore reaming to creep into and creep into efficiency of construction than use Double-bottom-plate reaming and improve 2 times, rig is when creeping in addition, more little being more easy in aperture is crept into, this technique plays the advantage of rig in slim-hole drilling, and by reasonable classification number of times, thus reasonable employment cylindrical rock bores counter bore diameter, when making cylindrical rock bore reaming, rock can be broken easily, and fall among aperture, use is dragged for sand hopper and is picked up, thus give full play to rig advantage, avoid repetition broken, improve drilling efficiency.
Accompanying drawing explanation
Fig. 1 is workflow diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1: required stake holes is Ф 1500mm, creeps into formation depth 15m; Use secondary hierarchical approaches (as shown in Figure 1);
A: first use Ф 1000mm cylindrical rock to creep into, take cylinder to drill through the preferential operator scheme of core, if get the unsuccessful Ф of the cooperation 1000mm of core to drag for sand hopper scarfing cinder, creep into 15m place;
B: use Ф 1500mm cylindrical rock to creep into row reaming, when creeping into 6.7m by design formulas in rock stratum, the rubble that reaming is cut, can fill up Ф 1000mm aperture space;
C: after Ф 1000mm aperture space is filled, use Ф 1000mm to drag for sand hopper and carry out scarfing cinder, and then use Ф 1500mm cylindrical rock to bore continuation reaming, when creeping into 3.7m again, Ф 1000mm aperture space fills up again, now re-use Ф 1000mm to drag for sand hopper and carry out scarfing cinder, so repeatedly operate, creep into projected depth 15m.
Embodiment 2: required stake holes diameter is Ф 1800mm, creeps into formation depth 20m, by using three grades of hierarchical approaches;
A: first use Ф 1000mm cylindrical rock to creep into, take cylinder to drill through the preferential operator scheme of core, if get the unsuccessful Ф of the cooperation 1000mm of core to drag for sand hopper scarfing cinder, creeping into the degree of depth is 20m place;
B: use Ф 1400mm cylindrical rock to creep into row reaming, when creeping into 10.2m in rock stratum, the rubble that reaming is cut, can fill up Ф 1000mm aperture space;
C: after little Ф 1000mm aperture space is filled, use Ф 1000mm to drag for sand hopper and carry out scarfing cinder, and then use Ф 1400mm cylindrical rock to bore continuation reaming, when creeping into 5.0m again, Ф 1000mm fills up in aperture again, now re-use Ф 1000mm to drag for sand hopper and carry out scarfing cinder, so repeatedly operate, creep into projected depth 20m;
D: use Ф 1800mm cylindrical rock to creep into row reaming, when creeping into 12.0m in rock stratum, the rubble that reaming is cut, can fill up Ф 1400mm aperture space.
E: after little Ф 1400mm aperture space is filled, use Ф 1400mm to drag for sand hopper and carry out scarfing cinder, and then use Ф 1800mm cylindrical rock to bore continuation reaming, when creeping into 4.8m again, Ф 1400mm fills up in aperture again, now re-use Ф 1400mm to drag for sand hopper and carry out scarfing cinder, so repeatedly operate, creep into projected depth 20m.
Be the rock stratum of stratum saturation uniaxial compressive strength more than 30Mpa in rock stratum, this rock stratum adopt grading technology of the present invention compared with traditional construction technique, can increase work efficiency significantly.
