Definitions

  • the continuous auger is generally driven in a combined movement of rotation-translation by means of a rotary motor which can itself move parallel to the axis of the pile being produced all along a slide mounted on a frame constituting the general framework of the pile machine.
  • a first phase (drilling phase) the downward rotation-translation of the drilling motor is maintained, in general, substantially less than the value corresponding to the direct screwing of the auger, taking into account the pitch of the latter, thus causing shearing from the ground along the auger envelope surface and some upward circulation of the material loading the turns.
  • the continuous auger is extracted without rotation by an upward translational movement of the drilling head, at the same time as concrete is pressurized under pressure by means of '' a pump so as to concrete the drilled hole as the auger is removed.
  • the concrete is brought into the conduit formed by the hollow barrel of the auger, through an injection head mounted, via a rotary connector, either directly on the hollow spindle passing through the drilling motor, or in the case of a solid spindle, laterally under the engine nose at the head of the tool line.
  • the fundamental condition for the correct realization of a pile by the process of the hollow auger is that of the absolute maintenance of the continuity of the concreting and consequently of the general pipe formed by the hollow barrel of the continuous auger.
  • This fundamental subjection therefore requires the use of a continuous auger of length at least equal to that of the pile to be produced, implemented in a single piece and requiring, consequently, a guide slide of the drilling motor of corresponding useful length. .
  • the present invention aims to put an end to the evolution towards gigantism of the material necessary for the realization of piles molded in the ground of great length and provides for this purpose, a device allowing the use of a continuous auger comprising joinable elements during work and allowing avoid breaking the continuity of the concreting line.
  • the present invention relates to a device for producing piles molded in the ground which comprises in combination: a slide, a motor capable of sliding along this slide and capable of imparting to a auger a rotation-translation movement, an auger driven by said motor extending parallel to the slide and comprising a hollow central shaft open at its lower end, means for bringing concrete to the upper part of said hollow drum and for discharging it at the lower end thereof, characterized in that - Said slide has a useful length less than the length of the pile to be produced; - Said auger has a lower part of useful length at most equal to that of the slide, consisting of a hollow barrel and a propeller integral with said hollow barrel, and an upper part consisting of a hollow internal element and at at least one removable external element in the form of an auger comprising a longitudinal discontinuity allowing it to be fitted laterally on the hollow internal element of said upper part, the hollow internal element of said upper part extending in the extension of the hollow barrel of said lower part or being mounted telescop
  • the inventive concept underlying the invention is based on the dissociation of the two functions performed by the continuous hollow auger, that is to say: - the drilling function, partial extraction of materials, support for the drilling walls, plug movable at the time of concreting, provided by the propeller of the continuous auger, - the concrete feed pipe function at the time of concreting, provided by the hollow barrel of the continuous auger.
  • the device comprises a tool line which can be rotated by a motor 6 with a hollow shaft which can be slid on a slide 16 mounted on a vehicle 17 to impart a movement of translation to the tool line.
  • the tool line has two distinct parts: - a lower part (Fig. 1) of length L / 2 consisting of a conventional hollow continuous auger section 1, of which the hollow shaft 2, of circular or polygonal section, is in communication with the outside at its lower end 3 allowing the concrete discharge back into the drilled hole when the time comes; - an upper part (Fig. 2 and 3) of useful length L / 2 consisting of an interlocking inner element and an outer element making it possible to reconstruct the continuity of the auger following the lower section once the latter has been pushed into floor.
  • the hollow internal element (FIGS. 4 and 5) or driving element, is a hollow tube 4 of polygonal external section (square for example) which can be secured to the upper part of the hollow barrel 2 of the lower auger section.
  • the lower part of the inner element 4 and the upper part of the hollow barrel 2 may have a frustoconical assembly profile, as shown.
  • This internal element has a length L / 2 increased by the length necessary for the crossing of the hollow shaft 5 of the rotation and translation motor 6 and for the mounting at its upper end of the rotary connector 7 for the concrete supply 8 .
  • the external element (FIGS. 6 and 7) is a hollow auger section 10 of length L / 2, the hollow shaft 11 of which has an internal section which closely follows the polygonal external section of the hollow internal driving element and whose the propeller is identical to that of the lower auger section.
  • the barrel 11 and the propeller of the upper hollow auger section 10 are interrupted vertically over a width allowing just the passage of the hollow internal drive element 4.
  • the device which has just been described has a discontinuity at the right of each turn of the upper continuous auger section, so as to allow passage for the hollow internal drive element.
  • This continuity solution is, geometrically, only of relatively small importance (8% of the arc for an auger of 60 cm in diameter and a square internal element of 15 cm side) and has no influence in the general case on drilling and concreting operations on the pile.
  • element 19 any other equivalent means could be used (movable flaps, articulated or not, etc. ).
  • the process for producing a molded pile of length L with the device of the invention is as follows: * At the start of operations the drilling motor is at the top of the slide of useful length L / 2 (Fig. 11). The tool line is formed, below the drilling motor 6, by the lower continuous auger section 1 and, through and above the drilling motor, by the hollow internal drive element 4.
  • the slide 16 of the pile machine 17 is dimensioned so as to be able to absorb the maximum torque of the motor. It is extended over a certain length by an auxiliary dart 18 whose role is to limit the deflections of the hollow internal drive element during drilling and concreting operations.
  • the base of the drilling motor is equipped with a mandrel 15 with hydraulic or mechanical clamping allowing, by locking on the hollow internal drive element, to exert an axial traction, retaining or pushing force on the line. of tool.
  • the lower auger section having been rotated into the ground (Fig. 12), the motor chuck is unlocked and the drilling motor reassembled at the top of the slide (Fig. 13).
  • the upper auger section 10 is then fitted onto the internal drive element with which it is thus secured in rotation and locked in position by means of the lower 13 and upper 14 flanges, thus preventing any lateral disengagement.
  • the drill motor chuck is locked on the internal drive element, preventing axial displacement of the upper auger section (Fig. 14).
  • the auger propeller having been thus extended and the mechanical continuity of the tool line being ensured, the pile drilling is completed (Fig. 15).
  • FIGS. 20 to 26 illustrate a variant of the device of the invention according to which the hollow internal element of the upper part of the tool is mounted telescopically inside the hollow barrel of the lower auger section.
  • references identical to those of Figures 1 to 7 are used to designate similar component parts.
  • the tool line used then comprises the following two distinctive parts: a lower part 1, of length l1, identical to that of the embodiment of the device described above, but whose hollow shaft 2 has an exclusively polygonal internal section, - An upper part of useful length l2 also consisting of two interlocking elements 4 and 10 making it possible to reconstruct the continuity of the auger following the lower section once the latter has been driven into the ground.
  • the inner hollow element of the upper part is a hollow tube 4 of polygonal outer section (square for example) matching the shape of the inner section of the hollow barrel 2 of the lower auger section so as to allow it to slide freely inside the latter.
  • An O-ring 21 mounted on the hollow inner member ensures sealing with the auger barrel at the time of concrete delivery.
  • the inner member has a length l2 of the increased length is necessary for the recovery hollow barrel inner member of the lower auger section, and the length required for connection with the supply of concrete 9.
  • the external element is a hollow auger section 10 identical to that of the previous embodiment and of length l2, except that it includes, at its top, a flange 22.
  • the motor 6 is integral with the upper end of the interior telesoopic hollow element 4 of the upper part and is lockable on the head of the lower auger section.
  • the drilling motor is at the top of the slide 16 of useful length l1.
  • the tool line is formed, under the drilling motor 6 by the continuous auger section and by the hollow internal drive element engaged inside the barrel of the auger section over the entire height of the latter.
  • the base of the drilling motor is equipped with a mandrel 15 with hydraulic or mechanical tightening allowing, by locking on the flange 13 of the barrel of the lower auger section, to exert an axial tensile, retaining or pushing force on the line. of tool.
  • the lower auger section having been introduced into rotation in the ground, the motor chuck is unlocked and the drilling motor reassembled at the head of the slide, deploying the hollow internal element over the entire its useful length l2 by the sliding of the latter in the barrel of the auger.
  • the upper auger section is then fitted onto the hollow internal element deployed and locked in position by the flange 13 and the mandrel 15 of the drilling motor is locked on a flange 22 provided at the top of the barrel of the upper auger section.
  • the pile drilling is completed.
  • the following reverse operations allow the concreting of the pile without cutting the concreting pipe: - raising of the drilling motor to the head of the slide, without rotation, in a coordinated connection with the concrete delivery, - unlocking of the motor chuck, disengagement and removal of the upper auger section, - lowering of the drilling motor leading to the penetration of the hollow internal drive element by sliding in the barrel of the lower auger section and locking of the mandrel on the head of the auger barrel, - raising of the drilling motor to the head of the slide, without rotation, in a coordinated connection with the concrete delivery.
  • the above variant of the device of the invention overcomes the presence of the dart 18 as an extension of the drilling slide.
