Abstract

Abstract A corrosion-protected anchoring rod for the anchoring of structural parts in the earth is adapted to be placed in a bore hole formed in the earth, with the rod consisting of a force transmission section adjacent the opening of the bore hole, and a force introduction section adjacent the end of the anchoring rod disposed furthest in the hole. 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 corrogated profile in order to increase the frictional resistance between the anchoring rod and the surrounding soil. The corrosion-prevented coverings of the anchoring 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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 171 words
A method of making an earth-anchoring, inclUding the steps of: providing 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; placing a smooth plastic tube over the force transmission section of the tension member; placing a corrugated tube, closed at one end, over the force introduction section of said tension member, and connecting same to said smooth plastic tube to form a continuous covering over the tension member; injecting hardenable building materials in the space between the corrugated tube and the force introduction section of the tension member; driving a drive pipe into the earth to form a bore hole; installing, prior to the hardening of said building materials, said tension member in the drive pipe; and withdrawing the drive pipe from the bore hole while simultaneously injecting hardenable building materials in the bore hole in the vicinity of the force introduction section of the tension member externally of the corrugated tube.
Claim 2
Independent Claim 171 words
A method of making an earth-anchoring, inclUding the steps of: providing 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; placing a smooth plastic tube over the force transmission section of the tension member; placing a corrugated tube, closed at one end, over the force introduction section of said tension member, and connecting same to said smooth plastic tube to form a continuous covering over the tension member; injecting hardenable building materials in the space between the corrugated tube and the force introduction section of the tension member; driving a drive pipe into the earth to form a bore hole; installing, prior to the hardening of said building materials, said tension member in the drive pipe; and withdrawing the drive pipe from the bore hole while simultaneously injecting hardenable building materials in the bore hole in the vicinity of the force introduction section of the tension member externally of the corrugated tube.
Claim 3
Dependent Claim 45 words
A method of making an earth anchoring as in claim 1 wherein the same hardenable building materials are injected between the tension member and the corrugated tube, and externally of the corrugated tube in the vicinity of the force introduction section of the tension member.
Claim 4
Dependent Claim 68 words
A method of making an earth anchoring as in claim 1 wherein the tension member comprises an array of steel bars surrounding an injection tube, and wherein the building materials are simultaneously injected externally of the corrugated tube in the vicinity of the force introduction section of the tension member, and by said injection tube into the space between the corrugated tube and said array of steel bars.
Claim 5
Independent Claim 129 words
A method of making an earth anchoring including the steps of: providing a corrosion-protection member by fusing a smooth tube of plastic to a corrugated tube of plastic of which the other end is closed; driving a drive pipe into the earth to form a bore hole; inserting said corrosion protection member, beginning with its corrugated portion, into said bore hole inside said drive pipe; introducing hardenable building materials into said corrosion-protection member and inserting a metallic tension member therein extending from the immediate neighborhood of the closed end of said corrugated tube to the immediate neighborhood of the open end of said smooth tube; and withdrawing said drive pipe from said bore hole while simultaneously injecting hardenable building materials in the bore hole externally of said corrugated tube.
Claim 6
Independent Claim 129 words
A method of making an earth anchoring including the steps of: providing a corrosion-protection member by fusing a smooth tube of plastic to a corrugated tube of plastic of which the other end is closed; driving a drive pipe into the earth to form a bore hole; inserting said corrosion protection member, beginning with its corrugated portion, into said bore hole inside said drive pipe; introducing hardenable building materials into said corrosion-protection member and inserting a metallic tension member therein extending from the immediate neighborhood of the closed end of said corrugated tube to the immediate neighborhood of the open end of said smooth tube; and withdrawing said drive pipe from said bore hole while simultaneously injecting hardenable building materials in the bore hole externally of said corrugated tube.
