Claims
- 1. A method of repairing a utility pole in situ comprising steps of:
- (a) excavating around said utility pole to a predetermined depth;
- (b) cleaning the surface of said pole;
- (c) treating said surface;
- (d) selecting and preparing a plurality of longitudinal woven fiber mat strips;
- (e) saturating said strips with the liquid composite;
- (f) positioning each strip with the longitudinal dimension of each strip substantially parallel to the longitudinal axis of said pole; and,
- (g) applying said strips sequentially and circumferentially with each succeeding strip overlapping its preceding strip, around the circumference of said pole to form a cylindrical encasement of desired thickness; wherein the manner of applying the saturated woven mat strips comprises:
- (i) fully saturating each strip by placing the woven mat into a tray filled with the liquid composite and rolling the mat strip with a paint roller;
- (ii) removing said saturated mat strips from the tray and aligning each with the longitudinal axis of the utility pole and then pressing it against the surface of the utility pole at the repair location;
- (iii) rolling said saturated woven mat strips with the paint roller to press the saturated mat against the pole surface and to ensure that no air bubbles are entrained;
- (iv) repeating the process with the next woven mat strip which is saturated in the tray; and then placed against the utility pole so that one half of the second mat strip overlaps half of the first mat strip already in place;
- (v) rolling the second mat strip with a paint roller to ensure that no air bubbles are entrained; and,
- (vi) repeating the saturated mat strip application until the composite encasement cylinder shell reaches the desired thickness.
- 2. A method of applying a bonded structural encasement to wooden poles comprising the steps of:
- (a) cleaning a portion of the surface of the poles;
- (b) selecting a material wherein: lengthwise fibers comprise from 50% to 80% of the total fiber; half of the remaining fibers total from 10% to 25% of the total fibers placed at an angle relative to the lengthwise fibers; and, the remaining 10% to 25% of the fibers placed at an equal angle relative to the lengthwise fibers in the opposite direction relative to the first angled fibers;
- (c) saturating woven fiber strips of said material with a composite resin;
- (d) selecting and applying a plurality of saturated strips to the clean surface in sequence with each succeeding strip overlapping its preceding strip around the circumference of said pole and substantially parallel to the longitudinal axis of said pole to form upon hardening into a cylindrical encasement;
- (e) applying an ultraviolet resistant coating to the exterior of the encasement; and,
- (f) pumping a fumigant into the pole to arrest biological agents.
- 3. A method of applying a bonded structural encasement to wooden poles comprising the steps of:
- (a) cleaning a portion of the surface of the poles;
- (b) selecting a material wherein; lengthwise fibers comprise from 50% to 80% of the total fibers; half of the remaining fibers total from 10% to 25% of the total fibers placed at an angle relative to the lengthwise fibers; and, the remaining 10% to 25% of the fibers placed at an equal angle relative to the lengthwise fibers in the opposite direction relative to the first angled fibers
- (c) applying a bonding agent to the cleaned surface prior to applying the saturated strips,
- (d) saturating woven fiber strips of said material with a composite resin;
- (e) selecting and applying a plurality of saturated strips to the cleaned surface in sequence, with each succeeding strip overlapping its preceding strip around the circumference of said pole and substantially parallel to the longitudinal axis of said pole to form upon hardening into a cylindrical encasement;
- (f) applying an ultraviolet resistent coating to the exterior of the encasement; and,
- (g) pumping a fumigant into the pole to arrest biological agents.
- 4. A method of repairing a utility pole in situ comprising the steps of:
- (a) excavating around said utility pole to a predetermined depth;
- (b) cleaning and treating the surface of said pole;
- (c) pumping a fumigant into the pole to arrest biological agents;
- (d) applying an ultraviolet resistant coating; and
- (e) applying a bonding agent to the cleaned surface prior to applying the saturated strips;
- (f) saturating woven fiber strips with a composite resin;
- (g) fully saturating each strip by placing the woven mat into a tray filled with the liquid composite and rolling the mat strip with a paint roller;
- (h) removing said saturated mat strips from the tray and aligning each with the longitudinal axis of the utility pole and then pressing it against the surface of the utility pole at the repair location;
- (i) rolling said saturated woven mat strips with a paint roller to press the saturated mat against the pole surface and to ensure that no air bubbles are entrained;
- (j) repeating the process with the next woven mat strip which is saturated in the tray; and then placed against the utility pole so that the second mat strip overlaps the first mat strip already in place;
- (k) the step of preparing said strips comprises selecting a woven fiber mat wherein lengthwise fibers comprise from 50% to 80% of the total fibers within a mat and half the remaining 10% to 25% of the fibers are placed at an angle relative to the lengthwise fibers; and, wherein the remaining 10% to 25% of the fibers are placed at an equal angle relative to the lengthwise fibers in the opposite direction relative to the first angled fibers,
- (l) selecting and applying a plurality of saturated strips to the cleaned surface in sequence, with each succeeding strip overlapping its preceding strip around the circumference of said pole and substantially parallel to the longitudinal axis of said pole to form upon hardening into a cylindrical encasement.
