Definitions

  • the subject of the present invention is a method of drilling by simultaneous percussion and rotation, and a setting device work of this process.
  • This device has a major drawback: to return to rear, the reamer must return to the axis of the casing, which is not an easy operation in itself, and which can be further complicated by the presence of sediment in the casing. In addition, the fact of moving from an eccentric position to a centered position requires a mowing turn and often causes loosening and we may have difficulty reassemble the entire device.
  • This device has the disadvantage, besides being extremely expensive, not to be suitable for horizontal drilling.
  • a goal of the present invention is to provide a method which can be used for horizontal drilling, which is inexpensive, and which allows drill variable diameters without having to change the size of the pilot cutter.
  • Another object of the invention is to propose a device for setting work of this process, which allows the user to choose the borehole diameter he wishes to make while using a hammer and a standard cutter, simply by fitting on a retractable crown surrounding this hammer wheel interchangeable.
  • the subject of the invention is therefore a new drilling method, characterized in that drilling is carried out by application simultaneous percussion and rotation.
  • the percussion is applied to the center of the borehole, and the rotation is applied to the periphery of the borehole.
  • the invention also relates to a drilling device comprising casing in which a main auger is located in the center of which passes a down the hole hammer at the end which is fixed a pilot cutter operated by the bottom hammer hole, characterized in that said pilot cutter wears a crown on the periphery of which the knobs are secured bore.
  • the device includes a return spring for the rollers.
  • the spring is housed in the body of the crown and acts on a nipple which is in direct contact with the base wheel.
  • the stud is provided with an O-ring.
  • the device further includes a hammer guide auger bottom of hole.
  • the guide auger and the main auger coincide so as to be an extension of each other.
  • Another object of the invention is the use of the method or the device for performing horizontal drilling, including in heterogeneous terrain.
  • FIG. 1 is a schematic longitudinal section of the drilling device according to the invention.
  • FIG. 2 is a schematic front view of an embodiment of a crown 7.
  • FIG. 3 is a horizontal section of another embodiment of a crown 7.
  • the drilling process according to the invention is carried out by the application simultaneous percussion and rotation. This is exactly drill in the axis of the casing 4 and carry out simultaneously a lateral bore. The lateral bore widens the hole to a sufficient diameter for the installation of the casing 4.
  • This process has the advantage of increasing the possibilities of larger diameter drilling while keeping the same pilot bit 6.
  • the percussion is applied to the center of the borehole, and rotation is applied to the periphery of the borehole.
  • the drilling device comprises a casing 4, in which there is a auger-extension 1, a downhole hammer 2 guided by an auger-guide 3 and a cutting edge 6 operated by the downhole hammer 2.
  • the casing 4, the downhole hammer 2, the augers 1 and 3 and the cutting edge 6 are standard.
  • a crown 7 carries on the one hand in its centers the pilot cutter 6, and on the other hand on its periphery the knurls 5.
  • the cutting edge 6 operates in percussion, and the bore wheels 5, which are secured on the periphery of the crown 7, operate in rotation.
  • the peripheral knobs 5 have the function of boring the hole to a diameter sufficient to allow the installation of the casing.
  • the number of knobs 5 is variable: it can be modulated by depending on the terrain. Preferably, an even number of scroll wheels, especially four to eight scroll wheels.
  • knobs 5 The size of these knobs 5 is variable. This characteristic is particularly interesting because it allows drill holes considerably enlarged compared to the diameter of the cutting edge 6 used.
  • knobs 5 are made of steel, in the form of tri-cones fitted with tungsten carbide spikes.
  • the shape of the wheel 5 is adapted to avoid jamming of the sediment up to the wheels.
  • the crown shown in Figure 3 in the form of gear wheel, the knobs 5 located on the teeth, allows a much greater release of sediment compared to the crown of circular shape shown in Figure 2.
  • the shape tooth reduces the risk of blockage and increases the penetration speed in medium hard terrain.
  • the device therefore comprises at least one spring 8 located in the crown 7 and making each wheel retractable in the casing 4.
  • the device comprises a spring by thumb wheel 5.
  • the knobs 5 are housed between the hammer and auger propeller 3.
  • the method and the device according to the invention are particularly studied and advantageous to carry out horizontal drilling, including included in heterogeneous terrains, and in particular drilling horizontal cased in hard rock, pebbles, moraines, embankments.
