Definitions

  • the present invention is the new application to an existing drilling method (percussive drilling with hammer out of the hole) of a particular circulation technique (double tube reverse circulation) already used in drilling but in totally different fields by example: tricone drilling.
  • tubular elements are screwed onto the top of the tube on which the drilling mechanism acts again.
  • the tube is used to inject a fluid (air, water, ...) whose role is to clean the cutter, to clear the bottom of the hole of the rock debris and to raise them to the surface through the annular space between tube and ground.
  • a fluid air, water, (7) whose role is to clean the cutter, to clear the bottom of the hole of the rock debris and to raise them to the surface through the annular space between tube and ground.
  • This method has 2 main drawbacks: - the fluid loaded with excavation debris can be polluted by other debris torn from the wall during the ascent, which prevents the succession of the lands crossed from being reconstituted. - the sleeves which serve to assemble the tubular elements between them protruding into the borehole, they contribute to the degradation of the wall and create a permanent risk of jamming.
  • the purpose of the present invention is to avoid these drawbacks and to carry out better quality drilling and to make "hammer drilling out of the hole" a real geological recognition tool by obtaining a good sampling of the land crossed and this, at a lower cost than traditional coring.
  • the water at the base comes out around the cutter, cleans the bottom of the borehole, then through the central hole of the tail lant and the inside of the tube rises with the rock debris to the surface.
  • the rock debris rises - as soon as they are taken (no pollution of the sample during the ascent) - very quickly (small section of the interior of the tube) - without being regrinded along the borehole by the sleeves, which makes it possible to obtain rock elements of a size facilitating their identification and study.
  • this debris is ejected on the surface either in the axis of the hammer by the needle which passes through the piston, or laterally under the hammer.
  • the drilling device is characterized in that around the axial tube is delimited, by a jacket, an annular volume which is connected, under the hammer, to a water injection head and, at the bottom of the hole, to the carving himself.
  • a stack of monoblock double-body elements composed of an axial tube and a male threaded peripheral jacket at one end and female at the other will be used, these threads serving to couple the monoblock elements. double-body them and to rotate them.
  • the tube is centered inside the jacket by a device which leaves it sheltered from the shock waves transmitted by the tube and which allows a certain sliding between tube and shirt.
  • the axial tube will be constituted by conventional tubular extensions threaded male at their two ends and joined together by sleeves.
  • the peripheral jacket will be formed by male threaded elements on one side, female on the other and screwed to each other.
  • the axial tube and the peripheral liner are only interconnected at their ends, under the hammer and at the cutting edge.
  • the rotary drive of the cutter can be ensured in two ways, either by the hammer acting on the tube, either by an independent rotation head acting on the jacket.
  • the shirt which, in all cases, progresses with the cutter, it can accompany it in two ways, either by not turning, or by being rotated either by the rotation head or by a linked device to the cutter.
  • the hammer has a tubular piston crossed by a hollow "needle" whose internal diameter is identical to that of the axial tube, which gives a strictly rectilinear path for the rock debris lifted by the water, so that it can be collected at the outlet of the tube above the hammer.
  • This particular configuration allows, subject to minor modifications to the cutting edge, the continuous ascent of carrots, thus further improving the quality of the sampling of the terrain crossed.
  • the rotary hammer 1 comprises a piston 2 which strikes in the known manner on the upper section 3 of a tube 4.
  • This consists of a series of tubular extensions such as 5, 6, 7, 8, 9 assembled one after the other.
  • each extension has at its top a threaded area 10 ( Figure 4) and at its base another threaded area 11.
  • the two threads are in the same direction and the assembly is carried out in the known manner by screwing in a threaded sleeve 12 of two adjacent threaded zones 10 and 11 ( Figure 4).
  • the tube (composed of tubular extensions) is screwed onto the cutting edge 13 by means of a threaded sleeve 14.
  • This sleeve 14 has the particularity of having the thread on the side opposite the cutting edge that is easier to unscrew. than those of the aforementioned zones 10 and 11.
  • a section 18 is provided on the body provided with longitudinal grooves 19.
  • the latter slide freely in the axial direction (double arrow 20, FIG. 2) between the corresponding grooves 21 provided inside the end 22 of the lower element 24 of a jacket 23 formed by screwing one after the other, elements such as 24, 25, 26, 27, 28.
  • jacket elements 24 to 28 are assembled in line with one another by male 30 and female 31 threads cut in the reinforced zones 29.
  • the pitch of these latter threads has the particularity of being in the opposite direction to the threads 10,11 , 15, 17. In other words, some are threaded "to the right", others "to the left".
  • the hammer 1 when the hammer 1 drives the drilling tube 4 through its top, it is the lower part thereof which, by the grooves 19, 21, rotates the foot of the jacket 23. Thanks to this arrangement, the rotation controlled by the hammer 1 tends to tighten all the screwed assemblies, both those of the tube 4 and those of the jacket 23.
  • centering pins 32 are provided on the inner wall of the jacket 23, distributed in the reinforced zones 29 and possibly in the jacket elements 24 to 28. These pins are intended to bear against the outside of the tube 4, to define around it an annular intermediate space 33 where the drilling fluid (air or water) will circulate.
  • a wide peripheral groove 34 is preferably provided on the drill bit 13 ( Figures 2, 7, 10) and longitudinal milled channels 35. It is also expected that the number of grooves male 19 (for example three in Figure 9) is lower than that of the grooves 21 of the sleeve 22 (for example six), which leaves free large passages of water or air 36 (for example three).
  • the upper section 3 is surmounted by a striking surface 37 and it has a lateral outlet opening 38 which communicates with the interior space 39 of the drilling tube 4.
  • annular space 33 is closed at its upper part by a sealed injection drum 40 which surrounds the tube 4 but remains isolated from the striking of the piston 2, while this space 33 opens laterally on a supply channel. 41 connected to an injection of compressed air or pressurized water.
  • the axial tube 4 is used to transmit to the cutting edge 13 the shock waves and the rotational movement.
  • the fluid (air or water) injected through the supply channel 41 descends into the annular space 33 then, through the passages 36, 34, 35 reaches the digging zone 42 located at the bottom of the hole which it cleans and d 'where it discharges the debris 43. These are raised by the central space 39, then ejected through the opening 38. Thus, the rock debris reassembled is not likely to be polluted by the terrain already crossed.
  • FIGs 12, 14 There is shown in Figures 12, 14, a possible embodiment of the head device connecting the tube 4, the jacket 23 and the hammer 1 according to Figures 1 and 2.
