The relevant a kind of method of the present invention, be used on ground or rock material is holed, especially carry out the boring of percussive drilling or rotary impact, and the hole carried out lining, wherein be installed in drill bit on the drilling rod through a ballistic motion and/or rotatablely move and form a boring and form a lining through a sleeve pipe by one.The also relevant a kind of device of the present invention, be used on ground or rock material is holed, especially carry out the boring of percussive drilling or rotary impact, and the hole carried out lining, wherein one be installed in drill bit on the drilling rod through a ballistic motion and/or rotatablely move and form a boring.
With different forms of implementation known have this be used on ground or rock material is holed, especially carry out percussive drilling or rotary impact boring, and thereafter to boring lining method and apparatus.Wherein be contained in drill bit on the drilling rod and make hole or the boring that extends under the certain condition on the length very, wherein by a ballistic motion and/or rotatablely move and form boring by one.When rotary impact is holed, by according to the suffered impact stress of drill bit this drill bit being rotated a certain angle separately; And this drill bit is loaded by a percussion tool again, wherein by the displacement that replace and intermittent impact of drill bit on direction of rotation, on the area that is being covered when being rotatablely moved by drill bit material is pulverized symmetrically and is smashed.Invade in the boring that extends under the certain condition on the length very and/or after finishing boring, can provide smooth and straight basically lining for preventing material, thus such as suggestion: adopt a respective design to get very solid sleeve pipe, wherein be applied to ballistic motion on the drill bit and be the part that sleeve pipe has been formed drill unit or propulsion plant thus strictly speaking through this sleeve pipe.Directly appreciablely thus be: for introducing required high impact forces, a kind of like this sleeve pipe should correspondingly be designed to solid and heavy wall, and the result who obtains thus is: must the corresponding bigger sectional area of drilling so that can consider the wall thickness of sleeve pipe.A kind of like this working sections that has increased for casing wall thickness especially requires longer time of cost correspondingly to make to hole and requires simultaneously the drill bit of a corresponding bigger and solid design under the hard rock situation.
Substitute to adopt a sleeve pipe to introduce impact force, also known in addition have other method, adopts time-consuming multiplex (MUX) to attempt after finishing boring drill bit withdrawn the hole and thereafter a bushing pipe or sleeve pipe are introduced and to be holed of spudding in as step with their.What see is that a kind of like this operator scheme only can be used for such occasion at once: wherein can stop material reliably and invade in the boring that is done, wherein also want the corresponding cross section that has increased of drilling one to introduce bushing pipe or sleeve pipe thereafter in addition certainly.For introducing a kind of like this have the very bushing pipe or the sleeve pipe of length, this pipe must also have a corresponding big wall thickness, so that can be introduced into reliably.Therefore also to adopt one that be complementary with casing size and have a larger-diameter drill bit in this case.
After introducing bushing pipe or sleeve pipe, can be used to solidify material around such as in this sleeve pipe, inserting an anchor pole and introducing a correspondingly quick adhesives in addition or alternatively.Alternatively, this lining also can be used for receiving conduit or similar item or is used to tapping and also is used for draining thus when providing perforation.
Therefore the objective of the invention is: be used on ground or rock material is holed, especially carry out the boring of percussive drilling or rotary impact from a kind of, and the method that lining is carried out in the hole gone out to send further develop, make it fast, simply and side by side insert at least one sleeve pipe substantially with boring formation.In addition, its purpose also is: adopt to have size that has reduced than existing form of implementation and the sleeve pipe of the wall thickness that especially reduces or a sleeve pipe that manys for being that a sleeve pipe or the many desired surcharges of sleeve pipe are reduced to minimum when the boring.Be to realize this purpose, its feature essence of the method according to this invention is: when boring with ahead running with at least one sleeve pipe that is connected with drill bit by be introduced in the boring in the axial direction by the tension that drill bit produced and after boring procedure finishes drill bit withdraw from from sleeve pipe with drilling rod at least in part.Thus, then by in adopting the ahead running that produces when the boring that one sleeve pipe that is connected with drill bit is only introduced in the axial direction by tension to hole according to the present invention, can guarantee: when making boring, just can directly carry out lining, so just can avoid the intrusion of issuable loosening rock and stopping safely boring to this boring.Also by at least one sleeve pipe is introduced in the boring by the only axial tension that is directly produced by drill bit, can be further with one very the sleeve pipe of thin-walled solve problem, because sleeve pipe need not resemble fully such as absorbing according to the situation of prior art and conveying capacity, impact force is applied on drill bit through a corresponding solid sleeve pipe in the prior art example, sleeve pipe of the present invention only must have an enough big rigidity, reduces because of casing buckling or cross section that possible loosening rock causes avoiding reliably.For guaranteeing after boring is finished, drill bit to be withdrawn the configuration that does not change the boring middle sleeve together easily with drilling rod, also advise drill bit is withdrawn from sleeve pipe with drilling rod at least in part according to the present invention.For this reason can be such as drill bit being divided into parts and the annular outside of an essence that an essence is the center around this central module, after this central module unclamped, this main member of drill bit was withdrawn from from boring by the inside of at least one sleeve pipe with drilling rod like this.
For guaranteeing when the rotatablely moving of drill bit: one or more sleeve pipes that should be connected with drill bit only are introduced on boring axial by a pulling force according to ahead running during in boring, preferably advise in addition drill bit rotatably is configured with respect to sleeve pipe.
According to a particularly preferred form of implementation, the method according to this invention is further developed as follows: after the central module of removing drilling rod and drill bit in sleeve pipe introducing one anchor pole and/or pour into a kind of curing materials.
Cut the material that gets off for extracting simply by drill bit, preferably suggestion has in addition: be cut the material that gets off and be extracted out from boring through inside and the free space between sleeve pipe and drilling rod that at least one perforation that is configured in the scope that is adjacent to drill bit is introduced in sleeve pipe.Extract from boring by being cut the free space of material between sleeve pipe and drilling rod that gets off, then can further reduce required boring cross section, can make like this boring outside dimension fully with the external diameter of outer tube suitable and advantageously only exceed a little this external diameter a little.
For solving proposing above of task, a kind of device according to the present invention is used for holing in ground or rock material, especially carry out the boring of percussive drilling or rotary impact, and boring carried out lining, wherein be installed in drill bit on the drilling rod through a ballistic motion and/or rotatablely move and form a boring by one, this device is characterised in that: drill bit is designed to be divided diametrically, and is trapped among dorsad at drill bit outer that an end of work plane makes at least one sleeve pipe around drilling rod be connected with drill bit through at least one coupling element under the pulling force draw in the boring vertically.By drill bit design is become to be divided diametrically, can guarantee to make after boring is finished such as the center main portion of drill bit and withdraw from from boring by sleeve pipe with drilling rod, at least one sleeve pipe directly acts on pulling force traction in the boring vertically through one and is inserted in the boring and to be maintained at boring after boring manufacturing finishes inner when making boring simultaneously.For when one of drill bit rotatablely moves, also guarantee to be installed in of placing outside the drill bit or several sleeve pipes only boring axially on stand under load, preferably suggestion in addition: drill bit rotatably is connected with above-mentioned sleeve pipe through this coupling element.
Obtain an especially simply coupling between the sleeve pipe of being brought in the axial direction by drill bit for can be the time at drill bit with at ahead running, preferably suggestion in addition: this coupling element is made up of the biasing outer peripheral areas of drill bit and sleeve pipe, it has profile mutually adaptive, that replenish, also insert if possible a moulding, the ring-type middleware.The biasing outer peripheral areas is such as can being designed according to stepped rising and complementary depression, can when adopting thin casing wall thickness also can guarantee then that by this biasing outer peripheral areas ahead running by drill bit obtains the reliable tractive to sleeve pipe.
Obtain a simply coupling between the sleeve pipe of bringing into by drill bit for can be the time at drill bit with at ahead running, also can advise alternatively: coupling element is made up of a plurality of ball, they are configured in and are arranged in the groove with a complete semi-circular cross-section on the drill bit and are arranged in a complemental groove that is adjacent on the cover pipe connections of drill bit, as this situation corresponding to according to another preferred implementing form of device of the present invention.By adopting the ball in the groove that also is configured in this corresponding recesses that both had been configured on the drill bit on one or more cover pipe connections, mode that then can ball bearing obtains one and simply is connected and be coupled accordingly between drill bit and one or more sleeve pipe, thus then make when holing by drill bit rotatablely move and/or rotary impact moves and obtains the relatively easy turnability of at least one sleeve pipe with respect to drill bit.According to a particularly preferred form of implementation, advise having on this ATM layer relationsATM: the connector of this at least one sleeve pipe and/or the join domain of drill bit are made up of by coating material metal, plastics or, wherein when adopting such as the ball formed by metal or plastics, can obtain be not only coupling element and also be a kind of coupling of each storeroom with connector of the sleeve pipe of groove or drill bit end part.Certainly, also can introduce such as the such sliding agent of oil the corresponding simple motion of groove the ball that is used for receiving the coupling element of forming by ball.
For avoid in ahead running, acting on power on the drill bit be introduced into one have under may situation one very small bore or very little wall thickness sleeve pipe and might cause the distortion of this sleeve pipe, suggestion in addition: the coupling element between drill bit and sleeve pipe is made up of a kind of damping material at least in part or is covered by a kind of damping material, and this situation is corresponding to another preferred implementing form according to device of the present invention.
For removing simply with being cut the material that gets off in the free space between inside pipe casing and drilling rod, can guarantee a corresponding less boring cross section like this, this cross section outside dimension complete and outer tube is complementary, for this reason also preferably suggestion in addition: one or more sleeve pipes have at least one through hole, especially a plurality of sleeve pipe hole or through hole on every side that be evenly distributed at its end regions towards drill bit.
As mentioned above, the grappling that sleeve pipe can not only be used to subsequently to introduce an anchor pole and therefore also usually be used for making a pair of object, but also can carry out draining such as providing through this manufactured boring and the sleeve pipe that is inserted into wherein.For this reason, preferably advise according to the present invention: sleeve pipe is designed to have on its whole length and is evenly distributed on the perforation of placing outside it.
For after making boring, guaranteeing simply the central module of drill bit to be withdrawn from, preferably suggestion in addition: drill bit is formed at least a central inner part and an exterior part, they can advance jointly but detachably intercouple together, and wherein the central module of drill bit has an external diameter slightly little with respect to the internal diameter of inner sleeve.For each elements of a kind of so many drill bits is coupled especially simple and reliablely, preferably suggestion in addition: rotatablely move for bringing into, the center exterior part of drill bit has a respective openings that departs from circular cross section and the exterior part by drill bit and is drawn.
As the front is repeatedly mentioned, sleeve pipe directly is introduced into via the axial loading that ahead running or drilling campaign produce by drill bit, therefore there is no need to provide an external diameter with respect to outer tube or outer liner tube to amplify many bore diameters, but is requirement according to existing technology when the follow-up lead-in bushing before this amplification.Therefore, the external diameter of outer tube is radially just enough corresponding to the outside dimension of boring fully.
Owing to only need resist possible intrusion material basically and needn't receive or transmit any force rate according to sleeve pipe of the present invention, therefore adopt the sleeve pipe of corresponding thin-walled just enough as if be used for the impact force of rotary impact boring.Preferably advise according to the present invention on this ATM layer relationsATM: sleeve pipe has the wall thickness of 1-3mm, especially 2mm, can directly see like this:, only must increase slightly and just enough whole surface that will remove or drilling for also only needing to adopt corresponding less material and material weight the sleeve pipe by this sleeve pipe is provided.
Be provided with according to a particularly preferred form of implementation: sleeve pipe is made up of metal or plastics, the condition that can conform very simply like this and especially adapt to the boring ground or the rock material that are formed therein.When a sleeve pipe of being made up of metal has a corresponding higher mechanical strength, a kind of structure so but has following shortcoming: bending that might sleeve pipe under loosening or loose ground or lithosphere situation or cross-sectional constriction and cause the overwhelming majority is the very infringement of the sleeve pipe of thin-walled, follow-up drill bit is withdrawn from become difficulty or be completely blocked, so also no longer possible such as the introducing that the follow-up anchor pole that provides is provided.Especially under this situation with loosening ground or rock material, that employing is made up of plastics, have certain flexible sleeve pipe and just prove and have advantage, even because when sleeve pipe temporarily changes its cross section, when drill bit further advances and sleeve pipe is brought into sleeve pipe also can recover its initial cross sectional shape again and therefore after boring is made, drill bit is withdrawn from very wellly and the possibility situation under also introduce an anchor pole thereafter.Especially when the sleeve pipe that adopts plastics to make, use the coupling element of aforesaid a kind of ball bearing type just to have advantage especially, so that can drill bit rotatablely move or in rotary impact when motion boring, obtained a kind of glitch-free as far as possible, turnability freely between drill bit and sleeve pipe because when the sleeve pipe that employing is made of plastics by drill bit with sleeve pipe bring into rotatably be considered to be imperfect.
Reduce possibly for will thisly overcoming in the ground of the material that includes easy intrusion or lithosphere and under the situation that therefore makes the frictional force that acts on the sleeve pipe become very big, then according to the invention provides: two sleeve pipes are by configuration and be retained as space one distance by being configured at separator or the stop part intermediate space between the sleeve pipe, that be preferably located on one of mutual surface in opposite directions of sleeve pipe fully with one heart mutually.By two ferrule configuration being become concentric fully mutually and being retained as space one distance, on the one hand since invade that material causes to the overload of outer tube and cause thus can avoid damage reliably to drilling rod to the damage of outer tube or when destroying, on the other hand then by in the sleeve pipe of complete mutually concentric arrangement only one be brought into the lining that can form with drill bit to boring, the external diameter of boring lining is on whole length and non-constant in boring.The external dimensions of the variation by this boring lining then especially can reduce to minimum with the frictional force that acts on the sleeve pipe in having than the zone of small bore lining diameter.
For guaranteeing two with one heart mutually a kind of like this telescope tube-in-tube structure or a kind of bringing into of separating of the sleeve pipes of configuration, the present invention is substantial to be characterised in that: the joint that is arranged at least that outside sleeve pipe is made up of multi-part and can throws off by relative rotation adjacent elements in the zone one of at least one joint of adjacent casing section, especially removably be coupled through a bayonet fittings and inner sleeve.This multiple piece construction by being positioned at outside sleeve pipe and but a kind of decoupling type of adjacent casing section connected to make and after the joint that unclamps two adjacent casing sections, can bring a casing section into that wherein another set of pipeline section then remains on original position and can obtain a kind of boring lining with variable-diameter thus.
For guaranteeing to obtain a kind of complete boring lining and a kind of desired to being positioned at bringing into of sleeve pipe inner or that be positioned at the outside, device according to the present invention is preferably designed so that: with one heart mutually the sleeve pipe of configuration has separately and is configured in the stop part in the end regions of at least one in the annular space between sleeve pipe, and in a connection piece zone, especially dispose in the sleeve member of an inner sleeve and be used for interconnective guide member and the decoupling zero part that is positioned at outside sleeve part.Because having, the mutual with one heart sleeve pipe that disposes is configured in the stop part in the end regions of at least one in the annular space between sleeve pipe, therefore can avoid being positioned at the disengagement completely between sleeve pipe inner and that be positioned at the outside reliably, and further can be according to the present invention by provide a sleeve member with guide member and decoupling zero part to guarantee certain inner sleeve section and overcoat pipeline section to be brought into requiredly.
For guaranteeing to withdraw the drill bit zone that is positioned at inside by the annular space of being made up of sleeve pipe, preferably suggestion has: the sleeve pipe that disposes mutually can be connected to the zone that is positioned at the outside of drill bit with one heart.Especially: be positioned at outside sleeve pipe at least and be fixed on the drill bit, can guarantee like this to obtain in the drill bit scope to bringing into reliably of outer tube at least.
