Abstract
Abstract A method and kit for repairing in situ a utility pole, especially a wooden one, when damaged at around ground level uses a sleeve (4) to surround a substantial length of the pole (1) and a non-shrink hardenabie pourable composition to occupy a clearance between the sleeve (4) and the pole (1) and form a solid core (7) bonded to both of them. so as to yield a very strong assembly. Preferably the skeve (4) is of two identical perts (6) clipped together round the pole, and the composition is a magnesium phosphate cement.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
78 words
A method of repairing in situ a utility pole (1) projecting from the ground (2) characterized by the steps of fitting a sleeve (4) around the pole (1); filling a clearance between the sleeve and the pole with a flowable hardenable composition; and allowing the composition to harden to a core (7) bonded at least mechanically to the sleeve (4) and to the pole (1) whereby to yield an assembly comprising the pole the core and the sleeve.
Claim 2
Independent Claim
78 words
A method of repairing in situ a utility pole (1) projecting from the ground (2) characterized by the steps of fitting a sleeve (4) around the pole (1); filling a clearance between the sleeve and the pole with a flowable hardenable composition; and allowing the composition to harden to a core (7) bonded at least mechanically to the sleeve (4) and to the pole (1) whereby to yield an assembly comprising the pole the core and the sleeve.
Claim 3
Dependent Claim
16 words
. A method according to claim 1 wherein the composition is at most a minimum-shrink composition.
Claim 4
Dependent Claim
29 words
A method according to claim 1 or claim 2 which includes excavating the ground (2) around the pole (1) and fitting the sleeve approximately equally above and below ground-level.
Claim 5
Dependent Claim
35 words
A method according to claim 3 wherein the excavation is to a depth of at least 0.2.5 m the sleeve is at least 0.5 m long and the clearance is between 10 and 75 mm.
Claim 6
Independent Claim
20 words
A method according to any one of the preceding claims wherein the length of the sleeve is about 2 m.
Claim 7
Independent Claim
18 words
A method according to any one of the preceding claims wherein the composition is a magnesium phosphate cement.
Claim 8
Independent Claim
25 words
A method according to any one of the preceding claims wherein the sleeve is anisotropic, with high tensile resistance in the direction of its length.
Claim 9
Independent Claim
29 words
A method according to any one of the preceding claims wherein the sleeve (4) comprises a plurality of identical parts (5), the parts being fitted together around the pole.
Claim 10
Dependent Claim
61 words
A repaired utility pole projecting upwardly from ground level and having a damaged region characterized in that a solid core (7) surrounds the damaged region of the pole (1) and is at least mechanically bonded thereto over its contact surface therewith; and a sleeve (4) surrounds the core (7) and is at least mechanically bonded thereto over its contact surface therewith.
Claim 11
Dependent Claim
61 words
A repaired utility pole projecting upwardly from ground level and having a damaged region characterized in that a solid core (7) surrounds the damaged region of the pole (1) and is at least mechanically bonded thereto over its contact surface therewith; and a sleeve (4) surrounds the core (7) and is at least mechanically bonded thereto over its contact surface therewith.
Claim 12
Dependent Claim
34 words
A utility pole according to claim 9 wherein the damaged region is around ground level and each of the core (7) and the sleeve (4) are approximately equally below and above the ground level.
Claim 13
Dependent Claim
19 words
A utility pole according to claim 9 or claim 10 wherein the core (7) is of magnesium phosphate cement.
Claim 14
Dependent Claim
27 words
A utility pole according to claim 9, claim 10 or claim 11 wherein the sleeve (4) has a length along the pole (1) of about 2 m.
Claim 15
Dependent Claim
29 words
A utility pole according to any one of claims 9 to 12 wherein the sleeve (4) is of a GRP material with its reinforcement running primarily along its length.
Claim 16
Dependent Claim
16 words
A utility pole according to any one of claims 9-13 wherein the pole (1) is wooden.
Claim 17
Dependent Claim
79 words
A kit for the repair in situ of a damaged pole projecting upwardly from the ground comprising a sleeve (4) for assembly around a damaged region of the pole in the vicinity of ground level to project into and from the ground (2) and be spaced from the outer surface of the pole (1) a hardenable pourable composition selected for at most minimum-shrink properties and for at least mechanical bonding to both the sleeve (4) and the pole (1).
Claim 18
Dependent Claim
79 words
A kit for the repair in situ of a damaged pole projecting upwardly from the ground comprising a sleeve (4) for assembly around a damaged region of the pole in the vicinity of ground level to project into and from the ground (2) and be spaced from the outer surface of the pole (1) a hardenable pourable composition selected for at most minimum-shrink properties and for at least mechanical bonding to both the sleeve (4) and the pole (1).
Claim 19
Dependent Claim
24 words
A kit according to claim 15 wherein the pole is wooden, the sleeve is of GRP and the composition is a magnesium phosphate cement.
