Definitions

  • the invention relates to a soil drilling device, more particularly but not exclusively, with a view to laying pipes.
  • a known method of laying pipes consists of digging a starting pit and an ending pit to a depth slightly greater than that of the pipe and descending into the starting pit, a device which, using '' a suitable tool will carry out a horizontal drilling until the arrival pit by force engagement of this tool under the push that at least one jack exerts on an elongated intermediate element, generally tubular made up of several sections placed one by one in a guide cradle associated with the jack to be connected to the previous sections and participate with them in the progression of the tool.
  • a drilling device consisting of a frame on which, via azimuthal adjustment members, are fixed two parallel cylinders whose respective ends of the rods piston are connected to each other by means of a guide connecting member associated with the cradle which is itself disposed between said cylinders where it receives the sections of the intermediate element allowing the progression of the drilling tool.
  • such a device in the retracted position, has the advantage of allowing the sections of the intermediate element to be put in place from above said device without requiring the place cylinder in front other than that necessary for the movement of the cylinder.
  • the two jacks must be synchronized and therefore supplied through precise regulation.
  • a result which the invention aims to obtain is a drilling device of compact design, requiring for its implementation only the production of a starting pit of very reduced dimensions.
  • the subject of the invention is a drilling device of the aforementioned type, in particular characterized in that the cradle for guiding the section of the intermediate element is produced by a blind hole inside the piston rod and whose axis is confused with the axis of said rod.
  • a drilling device 2 is lowered comprising a jack 3, the cylinder 4 of which, by means of azimuth adjustment members 5, 6, immobilized in a frame 7 pressed on and / or anchored to at least one (8) of the sides of the pit 1.
  • the various adjustment parameters suitable for ensuring the trajectory of the drilling member along an axis AA ⁇ , and, consequently, the orientation of the jack 3 relative to the frame 7 are determined according to the use of measuring devices specific to the surveyor.
  • the progression of the drilling tool 9 along this axis AA ⁇ is ensured by means of the jack 3, the end 10 of the rod 11 of its piston 12 is connected to a guide cradle 13 capable of partially housing a section of an elongate intermediate element 14, such as a tube, which guide cradle 13 causes, by its displacement along a substantially concentric axis, the axis AA ⁇ , the translation of the intermediate element 14 and by this, the progression of the drilling tool 9 .
  • the guide cradle 13 is produced by a blind hole 15 inside the rod 11 of the piston 12 and the axis BB ⁇ of which coincides with the axis CC ⁇ of the rod 11.
  • This particular design of the cradle 13 has the advantage of producing a drilling device 2 which suffices from pits whose transverse longitudinal dimensions are reduced to the maximum.
  • the particular design of the guide cradle 13 makes it possible to produce a drilling device 2 which is significantly more compact and, therefore, capable of being placed inside the starting pit 1, the dimensions are substantially close to those of the cylinder 3 in the retracted position.
  • the jack 3 is articulated to the frame 7 around a horizontal axis 16, perpendicular and contributing to the axis BB ⁇ of the cradle 13 for raising the cylinder to a vertical position.
  • the jack In order to release the maneuver, in the active position the jack rests on its azimuth adjustment device only by its simple weight.
  • the articulation of the jack 3 relative to the frame 7 is produced by an ear 17 crossed by the axis 16 of a yoke 19 preferably fixed to one of the faces 20 of the frame 7 by means of an adjusting member 5.
  • the drilling device 2 allows the drilling tool 9 to progress and this by successive thrusts of the jack and interposition of additional sections of intermediate element 14.
  • the length of the sections is substantially equivalent to the stroke of the jack.
  • the section 14 of the intermediate element does not enter the guide cradle 13 except at a depth less than the length of the piston stroke.
  • the bottom 22 of the blind hole 15 can be close to the head 23 of the piston 12.
  • Each section or at least some of them may furthermore, in order to limit their penetration into the cradle, present a stop means such as a local protrusion or a pin removable, pressing against the end of the piston rod or passing through an orifice which would be provided at this end, if only to place such a pin making it possible to grasp the sections one by one in order to allow their removal when this is desired.
  • a stop means such as a local protrusion or a pin removable, pressing against the end of the piston rod or passing through an orifice which would be provided at this end, if only to place such a pin making it possible to grasp the sections one by one in order to allow their removal when this is desired.
  • its front end can be chamfered.
