161 DRILLING APPARATUS EP92911558.2 1992-05-29 EP0682738B1 1997-04-23 VON BENZON, Ernst Benzoni
Drilling apparatus, in particular for drilling of holes preferably in soil consisting essentially of glacier deposits or comparatively soft rocks, said drilling apparatus comprising a drilling pipe with a cutter head, the drilling pipe consisting of two coaxial pipes forming an interspace, through which a drilling medium such as water or air can be introduced, and in which drilling pipe the cutter head is placed on the end, which is in front during the drilling, the cutter head comprising a number of hard metal bits and nozzles in between, through which the drilling medium can flow under pressure. To obtain an effective conveyance of the material removed during the drilling through the inner of the drilling apparatus, through which it should also be possible to introduce for instance liners, the drilling apparatus is constructed in such a way that the clear of the inner one of the coaxial pipes is unobstructed, that in addition to the nozzles in the cutter head a number of radially inwards directed nozzles is provided at a short distance from the cutter head and a number of ejector nozzles, which is directed obliquely inwards in a direction away from the cutter head.

163 Tool for use in system for in situ replacement of cutting means for a ground drill EP95108815.2 1994-06-15 EP0678653A3 1996-09-11 McLeod, Gavin Thomas; Egan, Matthew Vance

A tool (20) is described for transporting cutting segments (22) to and from a ground drill (12) to enable in situ replacement of the cutting segments (22). The ground drill is provided with seating means (30) for seating the cutting segments (22). The tool has a carrier cradle (176) onto which the segments can be loaded for transport to and from the ground drill (12) and is operable to cause the segments to slide relative to the tool when the tool passes a predetermined position within the ground drill, so that one end (70) of the segments can extend laterally of the tool an the segments engage the seating means (30) for retention in the cutting position.

164 Insert for use in retaining a cutting means in a ground drill EP95108814.5 1994-06-15 EP0678652A3 1996-09-11 McLeod, Gavin Thomas; Egan, Matthew Vance

An insert (24) is described for releasably retaining cutting means (22) in a ground drill (12). The insert is in the form of a substantially cylindrical member and is movable within the ground drill between an installation position and a retrieval position. In the installation position the insert (24) retains the cutting means in a cutting position between an outer circumferential surface (212) of the insert and an inner circumferential surface (26) of the ground drill. In the retrieval position the insert (24) is retracted to release the cutting means from between the outer circumferential surface of the insert and the inner circumferential surface of the ground drill.

166 SOIL AUGER EP88908888.6 1988-09-22 EP0334934B1 1995-04-12 PAXTON, Frank
A soil auger (10) particularly useful for removing a quantity of soil as a plug is provided, and is particularly adapted for use with a portable electric drill (40). The auger body (12) is substantially cylindrical with at least one open end (16) and provides a balanced unit for use at high rotational speeds. A series of teeth (20) at the lower margin of the auger are alternately inwardly and outwardly displaced from the plane of the cylinder. The teeth (20) may extend completely around the lower margin or only a portion thereof. Offset apertures (26) in the walls of the cylinder permit removal of the soil contained therein. A shaft (24) is mounted at the end of the auger (10) opposite the teeth (20) and adapted to be coupled to a hand held electric drill (40). In operation, the soil auger (10) enters the ground (42) driven by the drill (40) which rotates the auger (10). The teeth (20) of the auger (10) create a circular hole in the ground aroud a plug of soil, the plug of soil entering the interior (14) of the auger body (12) for subsequent removal.

A device for taking a soil sample can be used both in cooperation with a handling device and as a hand boring rod. The device has a probe (1) with a cylindrical tubular casing (9) the head end of which has a handling device (28) that closes the end of the probe (1) nearer the head of the tubular casing and that can be proviced with a percussion accessory (36) or with a connecting device to the handling device. The tubular casing (9) delimits a receiving space for the sample (7) or for a container for receiving the sample. The receiving space opens into the through channel of a tip (10) arranged at the foot end of the tubular casing, and a nonreturn device consisting of at least two spring wires (23) projects into the receiving space. To reduce the forces required for insertion and withdrawal, the tip (10) can be designed as a double conical frustum and have a casing section (17) which projects radially above the tubular casing (9).

Dans un procédé de forage thermique pour le percement de tunnels, les forages de grande profondeur et de prospection, on réalise par fusion uniquement une brèche définissant le profile extérieur du tunnel ou du trou de forage. On maintient d'abord immobile la carotte entourée par cette brèche, puis on la fait avancer sur une certaine distance à travers la zone de fusion. De manière appropriée, on découpe la carotte après son passage dans une zone froide et on la fait avancer en continu. La hauteur de la carotte initialement immobile est déterminée de manière à pouvoir injecter sous pression dans la carotte la roche fondue, la pression nécessaire à cette injection sous pression étant maintenue sensiblement constante indépendamment de la profondeur du forage.
172 Combination soil auger and soil core sampler with sample retaining capacity EP87104065.5 1987-03-19 EP0241750A3 1989-01-18 Vollweiler, Arthur Rick

A combination soil auger and soil care sampling apparatus has a cylindrical body with soil-cutting blades disposed at one end thereof and alternative cap and handle combinations attached at the opposite end for soil auger or soil core sampling use. In the soil auger mode, the body has an open cap with a bail and handle for augering into soil. In the core sampling mode, the body had a closed cap and handle combination and a removable sleeve insert within the body adapted to receive and hold a soil sample as the apparatus is rotated in the soil to be sampled. The sleeve insert is removeable for capping and retention of the soil sample.

176 Rotary drill bit for coring holes in subsurface formations EP86305041.5 1986-06-27 EP0212809A2 1987-03-04 Fuller, John

A rotary drill bit for use in coring holes in subsurface formations comprises a bit body having a shank 12 for connection to a core barrel 11, an outer peripheral gauge portion 14 for engagement with the peripheral wall of the hole being drilled, an inner peripheral gauge portion 15 defining at least a part of a central, generally circular aperture extending axially through the bit body, a plurality of cutting elements mounted at the surface of the bit body, and passages 20, 23 in the bit body for delivering drilling fluid to the surface of the bit body. Hydraulic sealing means 30, 31 are provided on the inner gauge portion of the bit and, in use, engage the outer surface of the core being cut by the bit. The hydraulic seal thus formed prevents or restricts flow of drilling fluid in an axial direction between the inner gauge portion and the core, and thus substantially reduces erosion of the core.
