Description
Technical field
The present invention relates to broken soft rock rig technical field, particularly a kind of reusable drilling apparatus and boring method preventing in boring drilling process and take out brill rear boring collapse hole.
Background technology
On-the-spot in geotechnical engineering and mine, often run into the situation of creeping into of punching in broken soft rock, if do not protected boring when holing or after pore-forming, then collapse hole phenomenon can occur, bring very burden to on-the-spot drilling construction, waste time and energy.The equipment that current engineering site carries out punching often does not have guard aperture measure, just drive drill bit to creep into simply by drilling rod, and bit diameter is greater than drilling rod, if there is collapse hole in drilling process, then only moves back brill; If remove collapse hole after boring, then need again to punch.For the defect of existing equipment, existing scholar's research devises relevant anti-collapse hole drill tool.Existing patent CN201460737U discloses a kind of anti-collapse hole drill tool, comprises drilling rod, drill bit and sleeve pipe.Though this patent is protected hole wall in drill process, when moving back brill, hypertonic drill lip may take sleeve pipe out of, and can damage sleeve pipe; Existing patent CN103277122A discloses one in breaking roof, bores bolthole and anchor rod anchored method, carry out guard aperture by sleeve pipe in drilling rod outer cover, though the effect of protection boring can be played, after pore-forming, can only drilling rod be exited, drill bit abandoned, in hole, adds cost; Existing patent CN103114810B discloses the anti-collapse hole of a kind of coal bed drilling and creeps into lower sleeve device and boring method with brill, comprise goat's horn drill bit, hosqe bit, combination propulsion plant, mesh sleeve and twist drill rods, when creeping into, mesh sleeve and drilling rod creep into simultaneously, can play the effect of anti-collapse hole preferably, but whether the undeclared sleeve drill bit of this patent can exit boring with twist drill rods.In addition; existing patent CN104453728A(anti-collapse aperture apparatus and drill bit structure thereof), existing patent CN203081286U(anti-collapse hole drill tool), existing patent CN102226389A(coal mine drilling anti-collapse hole pipe network and anti-collapse hole method) and existing patent CN203066865U(mono-kind can the anchor bit of reaming) etc. all related to protection to holing, but all do not mention the recycling to guard aperture pipe and drilling rod overcoat.
Summary of the invention
For the deficiency that the existing rig of above-mentioned engineering site and the anti-collapse hole drill tool researched and developed exist; the invention provides a kind of reusable anti-collapse hole drill and enter device and boring method; be applicable to bore operation in broken soft rock; available protecting can be carried out to boring in boring procedure and after removing brill; boring can also withdraw from spiral drilling pipe after being fully used; achieve reusing whole drilling apparatus, while guard aperture, greatly reduce again the cost of boring.
To achieve these goals, the present invention adopts following technical scheme:
A kind of reusable anti-collapse hole drill enters device and boring method, comprises drill bit, auger stem, spiral drilling pipe, alloy brill tooth, jam, rotor and latch; Auger stem head four directions handle is connected with drill bit, and afterbody four directions handle is connected with rig; Spiral drilling pipe to be combined with auger stem by jam and rotor and is integrated, and synchronously creeps into auger stem.
Described auger stem shank portion is cylinder, and head and afterbody are cubic handle, and the body of rod is welded with spiral lamination, and establish cylindrical thread hole in the handle of head four directions, aperture is identical with the drill bit afterbody diameter of bolt.
Described spiral drilling pipe is steel pipe, and internal diameter is slightly larger than the diameter of drill bit, and welded top has alloy to bore tooth, and outside weldings has conveyor screw.
Described jam is identical with the internal diameter of spiral drilling pipe with the diameter of rotor, and jam and rotor center all offer four-prism shape hole, and the hole cross section length of side is identical with the cross section length of side of afterbody four directions handle with auger stem head respectively.
The cubic handle of described jam, rotor, drill bit afterbody bolt and auger stem head, afterbody all offers barrel band hole, and jam, rotor and drill bit are fixed on auger stem by latch.
Described auger stem and drill bit axial line offer limbers.
The axis of described spiral drilling pipe, auger stem, jam and rotor overlaps.
Advantageous Effects of the present invention is:
To present invention achieves in broken soft rock punching and creeping into and remove protection to boring after brill; avoid the collapse hole phenomenon after the boring of traditional drilling apparatus; after boring is made full use of; also can withdraw from the spiral drilling pipe of guard aperture effect; thus achieve reusing a whole set of drilling apparatus, greatly reduce drilling cost.

Detailed description of the invention
The invention provides a kind of reusable anti-collapse hole drill and enter device and boring method, in order to make object of the present invention, technical scheme and advantage clearer, clear and definite, below with reference to
accompanying drawingthe present invention is described in more detail with specific embodiment.
as Fig. 1 ~ 5shown in, a kind of reusable anti-collapse hole drill enters device and boring method, and this device comprises drill bit 1, auger stem 5, spiral drilling pipe 4, jam 3, rotor 6 and latch 2; Auger stem 5 shank portion is cylinder, and head and afterbody are cubic handle 51,53, the body of rod are welded with spiral lamination 52, establishes cylindrical thread hole in the handle 51 of head four directions, identical with the drill bit 1 afterbody diameter of bolt.Spiral drilling pipe 4 is steel pipe, and welded top has alloy to bore tooth 41, and spiral drilling pipe 4 outside weldings has conveyor screw 42.Jam 3 is identical with the internal diameter of spiral drilling pipe 4 with the diameter of rotor 6, and four-prism shape hole is all offered at jam 3 and rotor 6 center, and the hole cross section length of side is identical with the cross section length of side of afterbody four directions handle 51,53 with auger stem 5 head respectively; The cubic handle 51,53 of jam 3, rotor 6, drill bit 1 afterbody bolt and auger stem 5, afterbody all offers barrel band hole, and jam 3, rotor 6 and drill bit 1 are fixed on auger stem 5 by latch 2; Auger stem 5 and drill bit 1 axial line offer limbers 7; The axis of spiral drilling pipe 4, auger stem 5, jam 3 and rotor 6 overlaps.
