Definitions

  • the invention relates to a method and an apparatus for producing drill holes.
  • a drill has already been used to drive in from the ground surface to the basement, along an oblique path, a drill string consisting of a large number of drill rods or rods, screwed one at the end of the other, and each having several meters of length.
  • the direction of penetration i.e. the drilling head which is at the front end of the drill string
  • the direction of penetration may be relatively good regulated, so that the drilling is done first flat and in a way oblique downwards, until reaching the prescribed depth, then continues drilling in an essentially horizontal direction, always thanks to the piloting of the drilling head.
  • the drill string is pushed forward, by the device drilling drive, attached to the drill string on the front side.
  • This train of stems is often rotated, and / or under the effect of water which escapes from the drill head under high pressure.
  • the materials encountered during drilling are then expelled, most often by internal passage hollow arranged through the drill string.
  • This process is mainly used to lay pipes on very long sections, for example 100 meters or more.
  • a drilling rig of this type which among other things must have a carriage directed obliquely downwards to guide the drill string, is large and weighs at least two tonnes because the weight of the drill is used part of the force stop used to compress the drill string towards the front.
  • the individual drill pipes will then only be flexible in their central zone, i.e. not in their extreme screwing zone with the two neighboring stems. Screwing by itself will preferably not include no play, as this would result in the removal of the adjustment possibilities of the orientation of the drill string as a whole. Like a drill string made up of tubes is, in the area of the screwing without play proper, much more rigid than in the central area of the individual stems, the drill string can, in screwing areas, be considered as not practically unable to undergo lateral displacement.
  • the drill string consisting of a very large number of individual rods very short is appropriate. It will indeed be possible, from a well of departure whose cross-section at the bottom will not be significantly greater than the small predefined section on the ground surface, arriving at a horizontal feed with a string of rods whose individual rods are, in the direction of the axis , connected to the rear end of the drill string in place. The length of individual stems will then be significantly shorter than the length, measured in the horizontal plane, of the cross section of the starting well.
  • the drilling drive device may further include a through hole for the drill string, so that the device drilling drive, contrary to what is otherwise usual, does not act not front side on the rear end of the drill string, but rather grips the drill string on its outer periphery, and keeps it in position around of the longitudinal axis, exclusively by a dynamic connection, both in the axial direction only in angular position, which makes it possible to push the drill string forward, turn or reverse.
  • a rotation of the drill string, to scrape or "grind” the material of soil in front of the drilling head, is then only interesting in cases individuals.
  • the rods to be added can each be screwed onto the end rear of drill string.
  • loader / extractor which has a motor attached to it clean
  • the rods to be added can each be screwed onto the end rear of drill string.
  • the drilling drive device can undergo translation longitudinal in one direction and in the other, in the starting well, parallel to the drilling axis, at least along the length of a rod individual.
  • the drilling drive device can thus move back and forth between an advanced position, which is immediately found at the start of the borehole in the starting well, and a recessed position, which is in the vicinity of the device rod loader / extractor, itself arranged against the opposite wall.
  • Both the loader / extractor and the drive device drilling are preferably installed in a tower or drilling rig, which is consisting of a lattice of metal tubes, part of which can be fixed and another mobile vertically.
  • the frame will preferably be on its walls devices, coated with plates to prevent earth from falling in the starting well.
  • This drilling tower (or at least its mobile part) is lowered, for example using a hand winch, from the top of the well.
  • the drill pipe store can consist of a chute vertical or oblique, in which the drill pipes are arranged horizontally one above the other. In the most position low, the chute is open on the front side, to allow the removal of the lowest rod from the store. In this picking position, the drill pipe is located in the vertical of a section of the drill axis, and can therefore be removed by the rod loader / extractor, which can move vertically relative to the drill tower.
  • the threaded sleeve located on the axis of this motor is then introduced by screwing into the drill rod located in the position of removal from the rod store. Note that this rod cannot be driven in rotation, due to the other rods which press on them, even of an additional mass.
  • the shop rods preferably ends in the drill tower below the ground surface but starts above the bottom surface and can then also project obliquely from the drill tower drill string, to make it easier to load additional rods by hand.
  • the lower part of the tower is advantageously wedged at the interior of the starting well by hydraulic cylinders for clamping horizontal action, for good support not only in the plane horizontal, but also in the vertical plane.
  • FIGS. 1 and 2a respectively show each the lower part of the drilling rig located in the well 2, while Figures 1b and 2b respectively show its upper part which partly exceeds the surface of the ground 5.
  • the drilling tower 11 is lowered into the starting well 2 by example using a hand winch, not shown in the drawings, and can, for this purpose, be guided vertically, for example in an auxiliary frame arranged above the starting well, using guide rollers, slides, etc.
  • Tower 11 has recesses open from below, arranged in these side walls.
  • FIGS. 1 and 2 do not include any train 6 of rods on the drilling axis 3, to facilitate understanding of the drawings, on the contrary of FIG. 3.
  • the train 6 of rods consists of rods 7 ( or elements) arranged one behind the other, screwed to each other at their ends.
  • Each element 7 has an axial length L1 (FIGS. 1a and 3) less than the distance d separating the front walls 2a and rear 2b of the well where the drilling machine was installed, as well as the length L2 (measured parallel to the 'axis of the rods 7) of the frame 11 (or at least of its part which descends into the well), between its vertical lateral uprights, front and rear, marked 11a, 11b in FIG. 1a.
  • FIG. 1a a copy 7d of these rods is screwed to the threaded sleeve 34 of the motor 13 belonging to the device 12 loader / extractor.
  • Each threaded rod 7 has on its outer periphery a annular groove 18 serving as detection means.
  • the charger / extractor 12 is moves essentially vertically.
  • the drill rod 7d is then moves into an essentially vertical transport gap 10.
  • the drilling drive device 9 can, on the drilling axis 3, slide the along guides 29 using hydraulic pistons 30.
  • the drilling train drive device 9 grips the rod 7 furthest back (i.e. still in the area of the drilling tower 11) and the entire drilling drive device 9 is moved to the left, passing through the position shown in the figure the.
  • the drilling drive device 9 thus moves alternately between the front wall 2a and the vicinity of the opposite rear wall 2b.
  • the device 9 can, in addition to this axial movement in the direction of the drilling axis 3, also turn the drill string 6, both during the linear movement only in a separate way.
  • a jaw rotating 33 suitable for tightening the drill string, can turn or pivot by relative to its housing 35, in a coaxial manner with the drilling axis 3. This way of doing is used to adjust the orientation, in cooperation with a bevel of known type in asymmetrical arrangement against the tip of the drill string.
  • the drilling drive device includes another jaw 32, called “separation” or “unlocking”, disposed in front of the rotating jaw 33, and which can keep the fixed drill string in rotation relative to the casing 35 of the drilling drive device.
  • An additional clamping jaw 21 is also arranged integral with the drilling tower 11, in the immediate vicinity of the drilling 3 relative to the drill string 6.
  • This clamping jaw 21 is it also, as can be seen better in FIG. 2a, made up of two jaws, directed transversely against the drill string. These jaws are driven by a hydraulic cylinder 21 'which, by one of its ends, is maintained in a fixed position relative to the drilling tower 11.
  • clamping cylinders 22a, 22b At the lower end of the tower, still below the device drilling drive 9, clamping cylinders 22a, 22b, current in the direction of the drilling axis 3, are permanently disposed against the tower drilling 11.
  • the cylinders 22a and 22b include a compression plate 25 at the free end of their piston rod.
  • the exit of the piston rods from these clamping cylinders 22 (which, if necessary, are driven by a hydraulic device), compress their plates compression 25 against the wall opposite the starting well 2, and thus the tower 11 against the side walls of the well 2.
  • the entire tower 11 is fixed in the starting well 2, which is important for the alignment, with respect to the started drilling hole 1, of the drilling axis 3 defined by the drilling drive device 9 with respect to the tower drilling 11.
  • the loader / extractor 12 essentially consists of the motor 13 with its threaded sleeve 34, which preferably is directly arranged on the motor output shaft.
  • This sleeve 34 is provided with a thread suitable for being screwed onto the rear thread of the rods 7, so as to allow their assembly one after the other. As seen on Figure 1a, it is then preferably an external thread, applied the along a conical surface, on the drill rod 9, in which case we use preferably a circular net shape.
  • the threaded sleeve 34 has at consequently an internal thread in the opposite direction, and the motor 13 is, for its axis of rotation, oriented parallel to the axis 3. The motor 13 can then move both in the direction of the drilling axis 3 and perpendicular to this direction (vertically along the frame 11).
  • the motor 13 is fixed to a motor frame 16.
  • the frame 16 can, using rollers 36 having on their periphery outer annular groove, move along the drilling axis 3, along two bars preferably spaced apart from each other in the vertical direction, serving as guides 17 for the engine frame.
  • Guides 17 are fixed on a carriage 14, which, preferably using rollers 39, can move in the vertical direction along the carriage guides 15 in the form of bars arranged, in the direction of the drilling axis 3, at a certain distance in the drilling tower 11, in the vicinity of the side 2b.
  • the motor 13 can, using the forklift loader / extractor 14, be moved in the vertical direction so that be aligned either with the drilling axis 3, in its lowest position, or, in its highest position (FIG. 2b), with a gripping device 23, arranged in the upper zone of the drilling tower 11.
  • This device lessee is actuated using a 23 'hydraulic cylinder, preferably double effect.
  • This store is for essentially consisting of a sheath 20 of the profiled type disposed in position oblique, the inclination increasing to the maximum to a position vertical.
  • the drill rods 7 are installed there from above.
  • the sheath 20 has a stop for the lowest drill pipe 7a and is open on the rear side of this pipe directed towards the motor 13.
  • the store 19 then preferably exceeds above the level from the ground 5, and extends outwards or laterally with respect to the tower drilling 11, so that the operating personnel can fill it more easily with drill rods 7.
  • the motor 13 When the motor 13 is in alignment with the drill pipe 7a housed in the magazine removal position 19, the motor 13 can, by a longitudinal displacement along its axis of rotation, accompanied with a rotation of the threaded sleeve 34, be screwed onto the drill rod 7a.
  • the drive of the latter in rotation is prevented by the weight of drill rods arranged above and possibly by the weight of a mass 42, also arranged in the magazine 19.
  • the descent to the device drive 9 of the motor 13, with the drill rod 7a ensures the transfer from this rod to the rod train 6, for connection.
  • the oblique chute 24 is arranged so that its the upper end is still below the gripping device 23.
  • step 4a the carriage 14 of the device 12 moves upwards (step 4a), to take a new elementary drill pipe 7a from the magazine 19.
  • the motor frame 16 is then located with the motor 13, in the rear position brought horizontally farthest from the borehole, that is to say towards the right edge 2b of the starting well 2 in FIG. 1a.
  • the carriage 14 is then moved along the guides 15 upwards, until the threaded sleeve 34 aligns with the thread of the rod 7a then the lowest, being in the position of removal of the store 19. Then the threaded sleeve 34 is moved on its axis of rotation towards the left, that is to say forward, against this drill pipe 7a, and is rotated by the motor 13 (step 4b), so as to screw the sleeve threaded 34 to the drill rod 7a.
  • This screwing is limited to a certain duration, from a few seconds, by a timer coupled to the changer motor 13.
  • the threaded sleeve 34 is moved horizontally in the direction axial by means of the motor 13, by the fact that the motor frame 16 is moved substantially horizontally relative to the carriage 14 along the guides of the engine frame 17a, 17b.
  • the hydraulic piston 37 performs this surgery.
  • a spring 38 is interposed between the hydraulic piston 37 and the frame motor 16 which moves under the effect of the latter, and there is preferably a spring 38a, 38b for each of the directions of movement.
  • the threaded sleeve 34 is preferably permanently installed on the output shaft of the motor 13.
  • this motor 13 is not disposed to remains against the engine frame 16. It is movable by means of supports in rubber, so that its axis of rotation can, relative to the frame of motor 16, achieve both a slight transverse offset and a variation angular.
  • step 4d the rotating jaw 33 is loose (step 4d), and the drilling drive device 9 (see FIG. 1a and FIG. 3) is brought to the right, along its two guides 29, until the rotating jaw 33 is in the area of the last new rod 7 which has been connected, and which can be tightened by the rotating jaw 33, for detaching from the drill rod 7 which has just been connected to the threaded sleeve 34, by rotation towards the rear of the motor 13 (step 4).
  • a displacement of the whole of the device 9 forwards makes it possible to move the drill string 6 forward, of the length of the new drill pipe 7, by the fact that the entire drilling drive device 9 is pushed forward, along the guides 29, using hydraulic pistons 30, preferably disposed of two lateral sides of the drilling tower 11 (force of about 2 tonnes).
  • the drill string is, before or during its advance, possibly rotated a little around the drilling axis 3, using the rotating jaw 33 (step 4f).
  • the entire rod loader / extractor 12 is again moved up, to get the next drill pipe 7 in the store 19 (step 4g). Thanks to the repetition of this operation, the train of rods 6 is formed to the desired length, and thus the borehole 1 advances in a controlled manner to its end point.
  • At least one locating means 28a sensors 28
  • sensors 28 which preferably are designed as inductive sensors, monitor the relative axial position relative to the drill pipe 7 located in the area of the drilling drive device 9, by the fact that one of the sensors 28a reacts when the annular groove 18 of this threaded rod 7 is stands exactly in front of him. If drill string 6 slides in the direction of the drilling axis 3 relative to the drilling drive device 9, the annular groove 18 leaves the area of this sensor 28a, and the latter emits a error signal.
  • step 5a we see that the drill string is too advanced into the borehole because the groove 18 of the element 7b has exceeded the detection means 28a and has been identified by detection means 28b.
  • step 5b we see that the drill string is in the good position because the detection means 28a is located opposite the groove 18 of element 7b.
  • step 5c we see that the drill string is too far back from the drilling drive device because the groove 18 element 7b is set back from the detection means 28a, and has been identified by the detection means 28c.
  • step 5b Each time in steps 5a and 5c, to reset the train drill rods in the correct position illustrated by step 5b, just back or forward the drilling drive device 9 along the axis to advance or reverse the drill string into the hole so as to place the detection means 28a opposite the detection means marking 18 (the groove) of the element 7b.
  • the annular groove 18 must have passed one of the two sensors 28b, 28c, which produced a corresponding signal. Therefore, we know the direction movement of the drill string 6 relative to the drive device drilling 9, and - preferably after fixing the drill string 6 in the hole drilling 1 using the clamping jaw 21 fixed permanently against the drilling tower - the drilling drive device 9 moves from again in the direction of the drilling axis 3, so that the sensor 28a either opposite the annular groove 18, that is to say resume the position prescribed.
  • a doctor blade not shown, usually consisting of one or several rubber lips or a rubber sleeve, for roughly clean the drill string 6 removed from the borehole 1.
  • the clamping jaw 33 of the drilling drive device 9 holds the drill rod located on further back from the drill string 6 (element 7c in step 6a), in which case the drilling drive device 9 is in the position, advanced by relative to the borehole 1, on the left edge of the starting well 1 of the Figure 1a.
  • the drilling drive device 9 is brought to the right (step 6b), the length of a drill pipe 7, then the drill string 6 is fixed in the borehole 1 by the fact that the clamping jaw 21 disposed against the drilling tower 11 fixes the rod of the rod string 6 which is now the penultimate, or another rod arranged further forward (step 6c).
  • the penultimate rod of rod string 6 is tightened by the separation / unlocking jaw 32 (step 6c).
  • the threaded sleeve 34 is then put in alignment position with the drilling axis 3 and is screwed on the rear end of the drill string 6 (step 6c), by the fact that the sleeve threaded 34 is facing forwards, that is to say generally in the direction of clockwise while being moved against the rear end of the train, until a sufficiently firm screwing between the sleeve and the last drill rod 6. This is controlled by a couple monitoring.
  • step 6c the rotating jaw 33 is rotated around from drilling axis 3 (step 6c), approximately half a turn towards the left (direction of thread opening) so that the last and the penultimate rod of rod string 6 are partially unscrewed.
  • the rotating jaw 33 then releases this last rod and is moves against borehole 1, forward, to grip the rod of train 6 which is now the last, and again remove it from the borehole until it can be moved away from drill string 6, as mentioned above. Simultaneously, or soon after, the unscrewing is continued and terminated by the threaded sleeve 34 and the motor 13, with the threaded rod therein finds (which was initially the last), and this, by a rotation of the thread in the opposite direction (rotation to the left), and simultaneously, when displacement of the rod changer, backwards, away from the stems (step 6d).
  • the drill pipe lying on the threaded sleeve 34 is carried in the entry area of the gripping device 23 located in the upper zone of the drilling tower 11, by raising the carriage 14 and possibly a simultaneous movement to the left of the motor frame 16 relative to the carriage 14 (step 6e).
  • the magazine 19 must be removed from the vertical path of the drill pipe by raising or lowering.
  • the drill rod thus transported presses on the chute pivoting 24 to move it away from its trajectory.
  • the drill rod 7k is, as can be seen in FIG. 2b, held by the gripping device 23.
  • the threaded sleeve 34 can then be loosened by a counterclockwise rotation of the motor 13 (step 6g), and by a simultaneous rearward movement of the engine frame 16 relative to the carriage 14.
  • the loader / extractor 12 is moved down, to take the next rod from the drill string 6 (step 6g).
