Definitions
- the present invention relates to a method for drilling, in particular percussion or rotary percussion drilling, and lining holes in soil or rock material, a drill hole being formed by a striking and / or rotating movement by means of a drill bit mounted on a drill pipe and by a cladding tube a lining is formed. Furthermore, the present invention relates to a device for drilling, in particular percussion or rotary impact drilling, and lining holes in soil or rock material, a drill bit mounted on a drill pipe forming a borehole by a striking and / or rotating movement.
- a hole or a hole which may extend over great lengths, is formed with the aid of a drill bit which is mounted on a drill pipe, the hole being formed by a striking and / or rotating movement.
- this core bit is usually rotated by a certain angle after each impact on the drill bit and is again acted upon by a striking tool, the systematic alternating displacement of the drill bit in the direction of rotation and the intermittent striking on the surface covered by the drill bit during the rotary movement the material is crushed and broken out.
- a suitably solid cladding tube being for example the striking movement is exerted on the drill bit via the cladding tube and thus, strictly speaking, the cladding tube represents part of the drilling or propulsion device.
- a cladding tube must be of correspondingly solid and thick-walled design in order to introduce the required high impact forces, which means that a correspondingly larger cross section must be drilled in order to take into account the wall thickness of the cladding tube.
- Such a cross-sectional area enlarged by the wall thickness of the cladding tube requires a correspondingly greater amount of time to produce the bore, in particular in the case of hard rock, and at the same time requires a correspondingly larger and solidly formed drill bit.
- an anchor can, for example, be introduced into the cladding tube and, additionally or alternatively, a correspondingly rapidly setting material for solidifying the surrounding material. rials are introduced.
- a lining can be used to hold lines or the like or, if perforations are provided, can be used to drain liquids and thus for drainage.
- the present invention therefore aims to develop, starting from a method for drilling, in particular impact or rotary impact drilling, and lining holes in soil or rock material, in such a way that at least one cladding tube is introduced quickly and easily substantially simultaneously with the formation of the borehole can. Furthermore, the aim is to use a cladding tube or cladding tubes with dimensions that are smaller than the known embodiments and in particular reduced wall thickness, in order to be able to reduce to a minimum the additional effort required for the cladding tube (s) during drilling.
- the method according to the invention is essentially characterized in that, with the advancing movement during drilling, at least one cladding tube coupled to the drill bit is introduced into the borehole in the axial direction by tensile action by the drill bit, and that after completion of the drilling operation, the drill bit is at least partially together is removed from the cladding with the drill pipe.
- the at least one cladding tube is introduced directly through the drill bit into the borehole by axial loading only, it can be found that a very thin-walled cladding tube is sufficient, since the cladding tube has no forces, as was the case, for example, in accordance with the prior art , the impact forces via a correspondingly massive cladding tube have been exerted on the drill bit, have to take it up and pass it on and only have to have sufficient strength to reliably prevent kinking or a reduction in the cross section in the event of loose rock.
- the drill bit can, for example, be divided into a substantially central part and an outer part which essentially surrounds the central part, so that after the central part has been released, this main component of the drill bit, together with the drill pipe, passes through the interior of the at least one cladding tube the borehole can be removed.
- the drill bit be rotatably arranged relative to the casing tube (s).
- the method according to the invention is further developed in such a way that, after the drill pipe and the central part of the drill bit have been removed, an anchor is introduced into the cladding tube (s) and / or backfilling is carried out with a hardening material.
- the removed material be introduced into the interior of the casing tube (s) via at least one opening arranged in the area adjoining the drill bit and is released from the borehole in the space between the cladding tube (s) and the drill pipe. Due to the fact that the mined material is brought out of the borehole in the space between the cladding tube or cladding tubes and the drill pipe, the required borehole cross-section can be further reduced, so that the outer dimensions of the borehole can essentially be matched to the outer diameter of the outer cladding tube and this only slightly exceed in a favorable manner.
- a device for drilling, in particular percussion or rotary percussion drilling, and lining holes in soil or rock material, wherein a drill bit mounted on a drill pipe forms a borehole by a striking and / or rotating movement, is essentially for solving the tasks set out above characterized in that the drill bit is split in the radial direction and that at least one cladding tube surrounding the drill pipe is positively connected to the drill bit in the longitudinal direction of the drill hole on the outer circumference of the drill bit at the end facing away from the excavation surface via at least one coupling element.
- the drill bit is divided in the radial direction, it can easily be ensured when the borehole is completed that, for example, the central main part of the drill bit can be removed from the borehole through the cladding tube together with the drill pipe, while the at least one cladding tube can be removed directly when the borehole is produced, it is introduced into the borehole by a pulling device which takes place in the longitudinal direction of the borehole and remains inside the borehole after the borehole has been completed.
- the drill bit is rotatable via the coupling element with the (the) cladding tube (s) is connected.
- the coupling elements of offset peripheral regions of the drill bit and the cladding tube have a coordinated, complementary profile, optionally with the interposition of a profiled, annular intermediate member are formed.
- Such offset circumferential areas which can be designed, for example, in the manner of step-like elevations and complementary depressions, can ensure that the casing pipe is carried along securely during the advancing movement of the drill bit even with comparatively thin wall thicknesses of the casing pipe.
- the coupling elements are formed by a plurality of balls, which have recesses on the drill bit which have a substantially semicircular cross section and complementary recesses are arranged on a connecting piece of the cladding tube or cladding tubes adjoining the drill bit, as this corresponds to a further preferred embodiment of the device according to the invention.
- a correspondingly simple connection and coupling between the drill bit and the cladding tube or the cladding tubes can be made in the manner of the ball bearing enable, whereby a correspondingly easy rotatability of the at least one cladding tube relative to the drill bit can be achieved during the rotating and / or rotationally striking movement of the drill bit during the production of the borehole.
- connection piece of the at least one cladding tube and / or the connection area of the drill bit are made of metal, plastic or a coated material, with the use of balls, for example made of metal or plastic, a coordination of the individual materials of both the coupling elements and the connecting piece of the cladding tube (s) having the recesses (see ) or the end piece of the drill bit.
- a lubricant for example oil, can also be introduced into the recesses for receiving the coupling elements formed by the balls.
- the coupling elements between the drill bit and the ( the) cladding tube (s) are at least partially formed from a damping material or coated with a damping material, as this corresponds to a further preferred embodiment of the device according to the invention.
- the (the) Cladding tube (s) has (have) at least one passage opening in its end region facing the drill bit, in particular a plurality of bores or passage slots evenly distributed around the circumference of the cladding tube.

- the cladding tube is introduced directly through the drill bit by an action in the axial direction during the driving or drilling movement, it is not necessary compared to the outer dimensions of the outer cladding or lining tube to provide an enlarged diameter of the borehole, as was required according to the prior art, in particular when a cladding tube was subsequently inserted. It is therefore sufficient that the outer diameter of the outer casing tube corresponds essentially to the outer dimensions of the drill bit in the radial direction.
- the cladding tubes used in the context of the invention essentially only possibly break in material rial have to withstand and no forces, for example impact forces for rotary impact drilling, have to absorb or transmit, can be found with correspondingly thin-walled cladding tubes.

- the cladding tube (s) is (are) made of metal or plastic, so that a correspondingly simple adaptation to the ambient conditions and in particular to the soil or rock material in which a borehole is made should be trained is possible.
- a cladding tube made of metal has a correspondingly high mechanical strength, it can be disadvantageous with such a design that loose or loose layers of soil or rock can impair the mostly very thin-walled cladding tube in the sense of kinking or narrowing the cross-section of the cladding tube , whereby a subsequent removal of the drill bit may be difficult or completely prevented, so that the subsequent insertion of an anchor, for example, is no longer possible.
- the use of coupling elements in the manner of a ball bearing is particularly advantageous in order to enable the undisturbed, free rotation of the drill bit and the sheaths during the rotating or rotary drilling movement of the drill bit , since a rotating entrainment of the cladding tube through the drill bit can be regarded as disadvantageous when using cladding tubes made of plastic.
- two cladding tubes are arranged essentially concentrically to one another and over Intermediate space between the cladding tubes, preferably spacing elements or stop elements arranged on one of the mutually facing jacket surfaces of the cladding tubes, are kept at a distance from one another.
