Definitions

  • 61-35 8 Claims ABSTRACT OF THE DISCLOSURE There is disclosed a method of anchoring a rod in a drilled hole, the method comprising the steps of first drilling the hole by employment of a drill head secured on the rod to be anchored, there also being affixed to the connected rod and drill head a tube larger than the rod and smaller than the hole and arranged to provide a flow passage into the hole about the rod and out of the hole about the tube, flushing out the hole as it is being drilled by fluid pressure directed through the flow passage, removing the tube from the hole while leaving the rod and drill head therein, and while removing the tube pressing a rod anchoring binding material through the ow passage and into the hole to ll the hole about the rod and drill head retained therein thus to securely anchor the rod in the hole.
  • the present invention concerns a method of anchoring rods or the like in drill holes in earths or rocks.
  • the present invention relates to a method by which the above drawbacks and difliculties will be completely eliminated, and by lwhich the rod in question will at every time extend all the way down to the bottom of the drilled hole, and further an absolutely complete and tight fillingup of the space around the rod in the drill hole is obtained with the greatest ease and swiftness.
  • the method according to the invention is substantially characterized in that a hole is first drilled by means of a rod and a drilling crown provided on the rod, the crown having an at least slightly greater effective or active diameter than a tube surrounding the drilling rod, and in that thereupon cement mortar or bonding means is pressed through the tube and into the drill hole during simultaneous or successive withdrawal of the tube out of the hole.
  • a fiush medium may be pressed into the tube during the drilling operation, preferably at the upper end of the latter and permitted to escape along the space worked up by the drill crown around the tube, and the binding means may suitably be forced in in a more or less direct succession to the interruption of the drilling work and the liush medium supply.
  • binding means any suitable binding means may be utilized, e.g. any cements mortars or bonds.
  • the .flush medium and the subsequent binding or bonding means may advantageously be forced or pressed into the tube through a sleeve means with a socket sealingly connected to the tube and the drill rod and provided with a connection for a supply line.
  • the rod and the tube may consist of interconnectable parts.
  • the shown device consists of two rods 1 interconnected by a sleeve 2, the inmost rod being in a drilled hole and provided with a drill crown 3.
  • the rods 1 serve both as drill rods and as anchoring members in the drill hole, and they may be made of a steel suited to anchoring purposes or of any material which does not need to have any interior flush or rinsing hole or passage.
  • the rods 1 are surrounded by two tube parts 4 interconnected by a coupling part 5 the diameter of the tube parts being at least slightly less than the effective or active outer diameter of the drill crown.
  • a space is formed, during the drilling, between the tubes 4 and the walls of the drilled hole.
  • a distance sleeve or the like 7 in sealing relation with the rod 1 is fixed at the upper portion of the upper rod 1 by a securing pin 6.
  • a sleeve member 9 is sealed by means of a sealing ring 8, the sleeve member 9 being provided with a pipe socket 10 forming an inlet for any ush medium, e.g. water o1' air, serving to remove drill chips from the drill hole.
  • any ush medium e.g. water o1' air
  • the sleeve member 9 is also tightly connected to a tube neck 11 with a lower cylindrical portion 12, which is received in the upper end of the upper tube part 4.
  • a flange 13 of the tube neck 11 determines the relative position of the tube 4 and the tube neck.
  • binding means which may be pressed in under considerable pressure, assures during all the withdrawal operation of the tubes 4 and the members connected to the latter that the drill crown 3 is firmly retained down against the bottom of the drill hole, thereby also retaining rmly the rods 1 connected to each other and to the drill crown.
  • the present invention also involves the important advantage that a complete filling up with binding means will also be obtained in the deepest drill holes, so that a never before attained anchoring strength is obtained. This means of course a very great advantage especially in grounds of bad quality.
  • any number of rods 1 may quite simply be joined together for drilling holes for anchoring members.
  • the sleeve 7 may be secured in the sleeve 9, so that it is not pressed out of the sleeve 9 ⁇ by the pressing in of the binding means.
  • a lid on the upper portion of the sleeve 9 it is of course also possible to obturate the hole in the sleeve 7 after withdrawal of the tubes and the members connected thereto.
  • the uppermost rod part 1 may have loops, hooks, catches or other formations -for attaching articles.
  • the binding means may be of a kind suited also for earth injection or grouting, whereby at the same time a reinforcement of a weak ground is obtained.
  • the herein described method of anchoring a rod in a drilled hole in the earth comprising the steps of first drilling the hole by employment of a drill head secured on an end extremity of the rod which is to be anchored, there also being provided and freely surrounding the rod and a portion of the drill head a tube having an inner diameter greater than the outer diameter of the rod and an outer diameter smaller than the drilling diameter of the drill head and the inner diameter of the hole being drilled with spacing provided at the portion of the tube freely surrounding the drill head thereby to provide a ow passage into the hole between the tube and rod and said drill head surrounding tube portion and out of the hole between the tube and the drilled hole wall, driving the drill head by applying power directly to the rod with the tube being stationary, ushing out the hole as it is being drilled by uid pressure directed through said flow passage, removing the tube from the hole while leaving the drill head and rod in place therein, and while removing the tube pressing a rod anchoring binding material through the tlow passage and into the 4 hole to fill the hole about the
  • Apparatus comprising a rod to be anchored in the ground, a drill head secured on an end extremity of the rod, a tube freely surrounding the rod and a portion of the drill head and devoid of driving connection with said rod and drill head and having an inner diameter substantially greater than the outer diameter of the rod and an outer diameter substantially smaller than the drilling diameter of the drill head and a hole in the ground to be drilled thereby and with spacing provided at the end of the tube surrounding said drill head portion thereby t0 provide a tlow passage downwardly between rod and tube and upwardly about the exterior of the tube, the rod being readily detachable and subject to being retained in the drilled hole while binding material is being pressed into the hole through the tube and the tube is being withdrawn away from the rod and drill head being anchored in the ground.
