  • the cladding tube is received in a receptacle of a jacket tube coupled to the drill bit and the cladding tube is subjected to a separate impact or compressive stress at the end facing away from the drill bit, it is made possible that a jacket tube coupled to the drill bit, which a has comparatively short length, is introduced during drilling, so that over the casing pipe a targeted and accurate drilling is ensured.
  • the cladding tube is introduced separately by a shock or compressive stress in the interior of the wellbore, so that not exerted by the drill bit or a, for example, in the field of drill bit arranged beater a correspondingly high energy to the entire, to be introduced into the borehole casing must become.
  • the subsequent cladding tube which usually has a lower strength, can be introduced into the interior of the borehole correspondingly simply and without excessive frictional resistance even by providing a correspondingly lower impact or compressive stress can.
  • the force acting on the end facing away from the drill bit compressive stress on the cladding tube is chosen to be less than a force exerted by the drill bit on the casing pipe tensile stress.
  • the fact that the compressive stress on the cladding tube is chosen to be less than the tensile stress exerted on the jacket tube ensures that the cladding tube, which is advantageously accommodated only with a simple plug connection in the receptacle of the jacket tube, is not introduced into the borehole to a greater extent. as this is the case for the drill bit and the jacket tube coupled thereto, so that no compression stresses are exerted on the cladding tube.
  • the drill bit is rotatably supported relative to the jacket tube and / or jacket tube ,

  • a device of the type mentioned is essentially characterized in that the cladding tube is received in a receptacle on the side facing away from the excavation surface of the drill bit end of a coupled with the drill casing casing, and that a shock or compressive stress is exerted on the end facing away from the drill bit end of the cladding tube.
  • a sleeve-like intermediate element for transmitting a force exerted by the drill string on the casing tensile stress for coupling the jacket tube to the drill bit.
  • Such a sleeve-like intermediate element can be produced in a simple manner and provides a proper and reliable power transmission between the drill pipe, which is coupled directly to the drill bit for performing the drilling work, and the jacket tube.
  • a sleeve-like intermediate element is provided for transmitting a pressure exerted by the drill string on the cladding tube compressive stress.
  • a stop face of the sleeve-shaped intermediate elements between the drill string and the casing tube and between the drill string and the end of the cladding tube facing away from the drill bit is formed in each case by an abutment surface enclosing an acute angle with the longitudinal axis of the drill string and the casing tube and the cladding tube, which with corresponding, complementary abutment surfaces of the drill string or an adapter coupled thereto.
  • abutment surfaces can be provided correspondingly inexpensively and precisely for a proper and reliable power transmission or insertion both in the jacket tube and in the cladding tube.
  • the abutment surface of the intermediate element between the drill string and the jacket tube is larger than the abutment surface of the intermediate element between the drill string and the end of the cladding tube facing away from the drill bit, thereby ensuring that, as already stated above, the tensile stress transferred to the jacket tube is greater than the impact stress applied to the jacket tube.
  • the drill bit is rotatably mounted relative to the jacket tube and / or cladding tube, so that is reliably prevented that in addition to the required rotational movement of the drill bit a rectilinear Both the jacket tube and the cladding tube are introduced into the interior of the borehole.
  • the outer diameter of the casing tube can be matched exactly to the dimensions of the borehole to be produced, wherein the casing tube has a correspondingly short length, so that frictional forces can be reliably overcome by a precisely fitting contact of the casing tube to the borehole inside wall, while the subsequent casing tube can be introduced easily and without large frictional resistance in the interior of the well corresponding reduced diameter.
  • the jacket tube has a cross section which is reinforced with respect to the cladding tube and / or increased strength. Characterized in that the jacket tube has a reinforced cross-section and / or increased strength, it is ensured that deviations from the desired drilling direction are prevented by the strength or rigidity of the jacket tube.
  • sleeve-like elements are provided for connecting mutually adjacent cladding tube elements, which overlap each adjoining end portions of Hüllrohremia and trained with projections or surveys or be formed which engage in complementary recesses or recesses on the circumference of the Hüllrohremia.
  • projections or elevations which engage in complementary depressions or recesses, can not only be produced simply and cost-effectively, but also enable a normally reliable drilling or reliable connection or coupling when extending sheath tube sections as a simple connection compared to conventional screw connections.
  • depressions or recesses and projections or elevations are not as easily exposed to damage, as is the case with known screw connections for extending cladding tube elements.
  • the sleeve-like elements are formed in the region of the projections or elevations with reduced material cross-section and that the projections or projections after arranging the sleeve-like elements on the outer circumference to be joined together Hüllrohr electrode can be formed according to the wells of the Hüllrohremia.
  • sleeve-like elements for connecting adjacent cladding elements is in accordance with a further preferred embodiment proposed that additional securing elements, such as bolt-shaped pins or pins, are provided for positioning and / or fixing of the sleeve-like elements, whereby connection positions can be maintained according to secure.
  • additional securing elements such as bolt-shaped pins or pins
