Abstract: A method and device for boring, particularly percussion boring or rotary percussion boring, a hole in soil or rock material and for forming an anchoring. A borehole is formed by inserting a drill bit, and a casing tube is placed inside the borehole during the boring process. Once the borehole is completed, the boring rods are detached from the drill bit and removed from the borehole. The periphery of the casing tube is provided with a number of passage openings for discharging hardenable material. A tensioning device for the anchor, particularly an anchor plate and a screw that can be screwed onto the casing tube, can be fixed to the end of the casing tube protruding from the borehole. Anchoring or fixing elements for anchoring the casing tube on the surrounding inner wall of the borehole are provided, in particular, on the end area of the casing tube oriented toward the drill bit.

Abstract: The invention relates to a method and device for the drilling, in particular the percussive drilling or rotary percussive drilling of holes (9) in the ground or in rock, a bore hole (9) being formed by a drill bit (1) that is mounted on a drill pipe (3), by a percussive and/or rotary movement. Several drill points (2), which can be coupled to the drill pipe (3) and driven independently of one another, are provided on the drill bit (1). According to the invention, the drill points (2) can be uncoupled from their rigid coupling to the drill pipe (3) upon completion of the drilling process and can be displaced towards the centre of the bore hole (9), thus permitting the entire drill bit (1) together with the drill points (2) and the drill pipe (3) to be simply and reliably removed upon completion of the bore hole (9).

Abstract: A method and device for boring a hole in soil or rock material and for forming an anchoring are disclosed. A borehole is formed by inserting a drill bit, and tensioning elements coupled to the drill bit are introduced into the borehole. After completion, the boring rods are detached from the drill bit and removed. The boring rods are provided with a hollow space in its longitudinal direction to introduce a hardenable fluid into the borehole. Anchoring or fixing elements for anchoring on the borehole's inner wall are provided on the drill bit at the end opposite the drilling surface and/or on the tensioning elements. The tensioning elements are subjected to a turning or twisting whereby shortening their effective length for tensioning or centering so that a centering and an optionally temporary tensioning of the tensioning elements can be effected before the hardenable material completely hardens.

Abstract: In a method and device for drilling, in particular percussion drilling or rotary percussion drilling, holes in soil or rock material, wherein a borehole is formed by a percussive and/or rotational movement carried out by a drill bit (1) mounted on a drill rod assembly (4) and an envelope tube and/or a jacket tube (15, 18) is introduced into the borehole, it is provided that the impact energy introduced by the drill rod assembly (4) is transmitted partially, particularly centrally, by the drill rod assembly (4) onto the drill bit (1) and partially via an impact shoe (10) cooperating with the drill rod assembly (4) onto the envelope and/or jacket tubes (15, 18), thus enabling the reliable introduction of the excavation or impact energy into the drill bit (1) as well as into the envelope and/or jacket tubes (15, 18).

Abstract: The invention concerns a method and device for boring, particularly percussion boring or rotary percussion boring, a hole (2) in soil or rock material and for forming an anchoring. According to the invention, a borehole (2) is formed by inserting a drill bit (4), and tensioning elements (10) coupled to the drill bit (4) are introduced into the borehole (2) during the boring process; Once the borehole (2) is completed, the boring rods (5) are detached from the drill bit (4) and removed from the borehole (2). The boring rods (5) are provided with a hollow space (22) extending essentially in the longitudinal direction of the boring rods (5) and serving to introduce a hardenable fluid into the borehole (2) as the boring rods (5) are removed from the borehole (2). Anchoring or fixing elements (14) for anchoring on the inner wall of the borehole are provided on the drill bit (4) at the end opposite the drilling surface and/or on the tensioning elements (10).
