Definitions

  • the force transmission section of the rod is covered with a smooth, corrosion-preventing covering, while the force introduction section is also covered with a corrosion-preventing covering having a corro gated profile in order to increase the frictional resistance between'the anchoring rod and'the surrounding soil.
  • the corrosion-prevented coverings of the anchor ing rod are suitably joined to completely enclose the anchoring rod, and a bonding composition is provided in the space between the corrogated covering and the tension member.
  • the present invention relates to a corrosionprotected anchor rod for the anchoring of structural parts in a bore hole in the earth, the anchor rod consisting of a steel tension member the force transmission section of which, i.e., the section closest to the opening in the earth, is provided with a smooth, corrosionpreventing covering, and the force introduction section of which, i.e., the section of the anchor rod disposed furthest in the bore hole, comprises a small sized body having a high coefficient of friction.
  • the invention furthermore concerns a method of producing anchorings in the earth with such corrosionprotected anchoring rods.
  • German Pat. No. 1,104,905 discloses a method of producing anchoring rods for anchoring structural parts in the earth in which a hole is made in the earth by means of a drive pipe, a tension member or anchor rod is introduced after the drive pipe has reached the final position of the bore, and thereupon the drive pipe is withdrawn while construction materials which harden in place are simultaneously introduced under pressure into the bore.
  • anchoring rods in which either the tension member consisting of a tension bar is connected, for instance, by threading to a drive point which is detachably seated on the drive pipe, or use is made of anchoring rods which are provided with a small sized or slender friction body in the section of the anchor rod where the tensile forces are introduced.
  • the object of the present invention is to provide a corrosion-protected anchoring rod in which not only is l terials is not reduced by the corrosion protection.
  • an anchoring rod in which the slender friction body is developed as a corrugated tube consisting of plastic.
  • the corrugated plastic tube is preferably connected with the tension member by a bonding composition which is injected into the space between the corrugated tube and the tension member.
  • a bonding composition known synthetic resins or grout can be used, or else mixtures of synthetic resins with grout may be employed.
  • Another object of the invention is to provide a method of producing anchorings in the earth in which the aforementioned anchoring rods are used in diversified fashion.
  • This purpose is achieved, inter alia, by a method in which the corrugated tube is first connected with the tension member in the manner that a smooth tube of plastic is placed over the force transmission section of the tension member and connected by welding to the corrugated tube, and the anchor thus produced is installed before complete hardening of the bonding composition in known manner through a drive pipe seated in a bore hole, and the drive pipe is then withdrawn with simultaneous introduction under pressure of building materials which solidify.
  • this tension member Prior to insertion into the bore hole, this tension member is preferably pushed into the interconnected tubes of plastic, without the corrugated tube being connected with the tension member in the region of the force introduction section.
  • These parts of the anchoring rod composed in this manner are thereupon introduced by the drive pipe into the bore hole, and the space between the tension member and the corrugated tube (by use of the injection tube) and the outer region on the earth end of the corrugated tube (by the use of the drive pipe) are simultaneously grouted with building materials which harden in place.
  • a corrugated tube of plastic as the small sized or slender friction body there is not only obtained a permanent effective corrosion protection of the tension member in the region of the force introduction section, but at the same time, the slender friction body required is formed by the plastic tube which in itself serves only for corrosion protection. It has namely, surprisingly, been found, as a matter of fact that a corrugated plastic tube is suitable as a friction body for the introduction into the surrounding earth of considerable I tensile forces which, depending on the development of the anchoring rod, are within the order of magnitude of between 30 and tons, even though such a tube would, on basis of the material of which it is made, appear entirely incapable of transmitting such high tensile forces.
  • FIG. 1 is a cross section through an anchoring rod installed in the earth
  • FIG. 2 is a view on a larger scale of the earth end of the force introduction section of the anchoring rod, seen in longitudinal section;
  • FIG. 3 is a cross section through the anchoring rod in the region of the force introduction section in which a bundle of steel rods has been used as tension member;
  • FIG. 4 is a schematic showing in longitudinal section of the grouting head seated on the air end of the drive pipe and having a tension member consisting of a bundle of steel rods and located in the drive pipe.
  • the anchoring rod 1 consists of a tension member 2, the earth-side end of which is externally surrounded in the region of the force introduction section 3 by building materials 4 which have been injected into the earth and harden in place.
  • the anchoring rod 1 is braced at its air end by means of an anchor head structure 6 against a timbering 5 supporting an excavation, for instance, an embankment.
  • the tension member 2 is covered over its free end, i.e., the force transmission section 7, by a smooth plastic tube 8 serving as a corrosion-protection member.
  • a corrugated plastic tube 9 which is connected at the joint 10 with the smooth plastic tube 8, for instance by welding.
  • the corrugated plastic tube 9 defines the small sized or narrow friction body of the anchoring rod.
  • the corrugated plastic tube 9 is closed at its earth end by a bottom 11.
  • the space between the corrugated plastic tube 9 and the tension member 2 is filled with a bonding composition 12.
  • FIG. 3 there is shown the tension member 2 which consists of a bundle of steel bars 13 having at its center an injection tube 14.
  • FIG. 4 shows the air end of the anchoring rod 1, which in this case consists of a bundle of steel bars 13 arranged around an injection tube 14 during the injection of hardenable building materials into the space between the tension member 2 and the corrugated plastic tube 9, and the simultaneous introduction of hardenable building materials 4 into the region of the force introduction section 3 of rod 1.
  • the anchoring rod 1 is seated in the drive pipe onto which there is screwed an injection head 16 which is connected by a hose 17 with an injection pump (not shown).
  • a method of making an earth-anchoring including the steps of:
  • a corrosion-protected earth anchoring including an elongated tension member having a force introduction section adjacent one end thereof, and a force transmission section adjacent the opposite end thereof;
  • a method of making an earth anchoring including the steps of:
