Definitions

  • the invention concerns a process for the drilling of holes in a mountain range covered by earth or loose rocks, with an annular rock cutter bit attached on a casing pipe and adapted for percussive rotary drilling as well as with a percussive rock bit provided with a central flushing channel and arranged on an auger stem, whereby, if need be, the auger stem and/or the casing pipe are attached in a crown piece transmitting the strokes of the hammer.
  • the drill cuttings are carried along by the pressure of the flushing agent, and they will rise to the surface and into the open outside of the casing pipe.
  • stoppages occur in the flushing agent pipe outside of the easing pipe which prevent or impede the constant removal of the drill cuttings, as a result of which the progress of drilling is unfavorably retarded.
  • FIG. I shows the longitudinal section through a crown piece with a casing pipe
  • FIG. 2 shows a crown piece with a casing pipe and an auger stem
  • FIG. 3 shows the front view of the two rock cutter bits
  • FIG. 4 is the front view of the two rock cutter bits of a different design.
  • An auger stem 1 has been inserted into a rock drilling machine, not shown in the drawing, preferably a hammer drill (sinker drill), which casing has at its free end a plug-in stump 2, which is screwed into one end of a crown piece 3.
  • a hammer drill sinker drill
  • an inside sleeve 4 has been screwed in with which a casing pipe 5 is connected. It is possible, depending upon the drilling progress, to add additional casing pipes 5 via additional sleeves 4.
  • an annular rock cutter bit 6 has been attached.
  • the crown piece 3 has a sufficiently large opening 7 lateral its axis.
  • the percussion piston of the rock cutter drill transmits the percussion energy via the auger stem 1 to the plug-in stump 2 which conducts it further to the crown piece 3 and from the latter via the casing pipe(s) 5 to the annular rock cutter bit 6.
  • the pertinent layer of ground or gravel is crushed and is displaced mostly laterally, whereby the material of the layer concerned is forced partly outward around the jacket of the head, while the rest escapes inward, arches up, and reaches the open air through the. ejection opening 7 in the crown piece.
  • the casing pipe After the casing pipe has been driven ahead by one length of pipe, it is separated from the crown piece and left in the bore hole in this position. Thereupon. the auger stem, with the plug-in stump 2 and the crown piece 3, is pulled out of the rock cutting drill. Subsequently, an auger stem, provided with a percussion rock cutter bit, which is used generally, is in serted into the rock cutting drill and now the layer inside of the pipe casing located in the bore hole is drilled under ample flushing. At the same time, the flushing agent will emerge at the free end of the casing pipe, together with the drill cuttings.
  • the auger stem is pulled out of the bore hole and is removed from the drilling machine.
  • an additional casing pipe by means of a sleeve, to the free end of the casing pipe projecting from the bore hole. and said pipe can be connected with the auger stem provided with the crown pipe and newly inserted into the rock cutting drill,.and drilling with the casing pipe can be continued.
  • the crown piece is again removed and the core is again drilled with the auger stem inside of the casing pipe. This process is repeated until the earth and loose rock is penetrated and the mountain is reached, and the bore hole can be advanced (driven in) exclusively with the auger stem.
  • the drilling with the auger stem inside of the casing pipe, stuck in the bore hole, is troublesome or there is danger that either the casing pipe or the rock cutter bit will suffer some damage through this drilling process, in which case it will be advantageous to use a rod system according to FIG. 2. to which alternatingly a casing pipe or an auger stem has been attached.
  • the crown piece has not only a thread for joining on ofthe casing pipe 4, but it also has a central bore 8 with a flushing channel 9. so that for the drilling of the material which is inside of the casing pipe 5,
  • a percussive rock bit I2 can be used whose auger stem 10 is inserted into the axial bore 8 of the crown piece 3 and thus can be guided centrally inside of the casing pipe.
  • the views of the front surface of the cutter bits show the annular channel 13, through which the drilling mud is removed.
  • the percussive rock bit 12 of the FIG. 4 has recesses 14 at its periphery through which the drill cuttings can be conducted more favorably into the channel 13 between the casing pipe and the auger stem.
  • a method of drilling holes through earth and loose rocks covering solid rock comprising:
  • a method as claimed in claim 1 comprising the additional step of adding new sections of easing pipe and auger stem as required.
  • a crown piece for transmitting percussive energy. said crown piece having an ejection opening in its wall for drill cuttings and coupling means for being removably attached to at least one casing pipe and auger stem;
  • annular rock cutting bit attached to said casing pipe and adapted for cutting an annular bore hole having a core
