Definitions
- the invention relates to a method of installing a ground anchor comprising screwing into the ground an anchor having a shank and at least one helical blade on the outside of the shank and injecting a hardening fluid into the ground surrounding the blade through bores provided in the shank and communicating with an interior passage of the shank.
- Such a ground anchor as described for example, in GB-A-1,115,796 is employed for many 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 satisfactory 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 installed in a simple manner such that 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 prior to injecting the hardening fluid air or gas is passed through the interior passage and bores of the shank and injected into the ground surrounding the blade to drive out water contained in the ground.
- the air or the gas will drive out any water contained in the soil surrounding the ground anchor so that the subsequently injected fluid can penetrate into the surrounding soil over a large distance away from the ground anchor without mixing with water.
- an effective consolidation of the soil around the ground anchor and an effective fixation of the ground anchor are obtained.
- Hardening fluids solidifying within a comparatively short time after injection into the ground are known, for example, from DE-A-2,819,974 and 2,820,963.
- 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 block 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 radially 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 exterior 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 hardening fluid can be injected through the passage 9 and the bore(s) 10 into the ground surrounding the ground anchor.
- the composition of the hardening 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 pressure of the air or the gas in the passage of the ground anchor will preferably be maintained during the change-over from the injection of air or gas to the injection of the hardening fluid.
- 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 one another in the direction of length of the shank.
- the injection can be carried out beneath and above the lower and upper blades respectively by providing suitable bores 10 in the shank.
