Definitions

  • the invention relates to a method of arranging a ground anchor into the ground, said anchor comprising a shank and at least one helical blade arranged on the outer side of said shank, the shank with the blade being screwed into the ground.
  • Such a ground anchor as described, for example, in German Patent Application 1,634,671 is employed for may purposes, for example, for fixing or anchoring dam walls along channels and rivers, for anchoring high masts, air halls and the like.
  • Such anchors screwed into the ground generally have a satisfying effect, the force that can be exerted on such anchors always strongly depends upon the conditions of the ground into which the anchor is screwed. During drilling operations it has been found, in practice that even at small intervals appreciable differences in the solidity of the ground can be assessed.
  • the invention has for its object to provide a method of the kind set forth by which the ground anchor can be arranged in a simple manner such that in addition a satisfactory ground condition is safeguarded so that optimum fixation of the ground anchor in the ground is invariably obtained.
  • this can be achieved in that after the ground anchor is screwed into the ground first air or gas is-injected into the ground surrounding the blade, after which a hardening fluid is injected.
  • Hardening fluids solidifying within a comparatively short time after injection into the ground are known, for example, from German Patent Application 2,819,974 and 2,820,963.
  • a particularly suitable ground anchor for carrying out the method according to the invention is obtained, when the shank has, over at least part of its lenght, a passage which is open at least near the top side of the anchor and which communicates with the external side of the anchor through at least one bore located near the helical blade.
  • the hardening fluid can be injected through the passage and the bore into the ground surrounding the anchor.
  • the ground anchor illustrated in the Figure comprises a hollow shank 1 surrounded over part of its circumference in known manner by a helical blade 2.
  • the hollow shank 1 has at both ends inner screwthread 3 and 4 respectively.
  • a correspondingly screwthreaded end 5 of a closing piece 6 for the shank is screwed Into the lower end of the shank with the screwthread 4 a correspondingly screwthreaded end 5 of a closing piece 6 for the shank.
  • the closing piece 6 has a bevelled tip 7.
  • the lower end of the shank may be closed in a different manner, for example, by welding the closing piece 6 to the shank or, for example by flattening and/or sealing by welding the lower end of the shank 1.
  • the top end of the shank is surrounded by a rectangular or square block 8 having a bore for receiving the top end of the shank.
  • the b&ock 8 is welded to the top end of the shank.
  • the block 8 may be used for mounting a tool for screwing the anchor into the ground.
  • the Figure shows furthermore that near the blade at least one more or less helically extending bore is provided in the wall of the shank 1 so that the passage 9 in the interior of the shank communicates with the )uter side of the ground anchor through said more or less radial bore 10.
  • a plurality of such bores will be provided along the length and the circumference of the shank.
  • a hose or the like can be connected with the open top end of the passage so that with the aid of a pump or the like air or gas can first be injected through the passage 9 and the bore(s) 10 into the ground surrounding the anchor.
  • the introduced air will drive away the water contained in the ground surrounding the ground anchor.
  • a fluid can be injected through the passage 9 and the bore(s) 10 into the ground surrounding the ground anchor.
  • the composition of the fluid employed is such that after a comparatively short time this fluid will solidify in the ground so that the ground surrounding the anchor is consolidated.
  • the blade 2 may, of course , be designed so that it extends through more than 360° around the shank.
  • the shank may be provided with a plurality of blades overlapping ene another in the direction of lenght of the shank.
  • the ground located between said blades will be solidified, which is advantageous for withstanding both tensile and pressing forces.
  • the injection can be carried out beneath and above the lower and upper blades respectively by providing suitable bores 10 in the shank.
