Abstract
This invention provides a method for repair for poles which have been damaged which is easily transportable, simple to install, and easily adaptable to many classes of poles. The method involves excavating around the pole, cleaning the surface of the pole, pumping a fumigant into the pole, cutting back to solid wood, installing a high compressive strength filler, applying a bonding agent to the clean surface, and then applying strips of a composite fiberglass mat and resin to the pole in a controlled manner until a desired encasement thickness has been achieved. The repair is completed by application of an ultraviolet resistance coating to the pole.
Claims21
A composite repair encasement apparatus for poles comprising:
- (a) a plurality of woven glass mat strips;
- (b) a liquid resin for saturation of the woven mat strips which subsequently hardens to form, in combination with the mat strips, a fiberglass encasement repair cylinder for a pole;
- (c) a bonding agent for application to the pole prior to the installation of the saturated woven mat strips;
- (d) a fumigant pumped into the pole to arrest biological agents;
- (e) an ultraviolet resistant coating for application to the exterior of the encasement;
- and,
- (f) a liquid quick setting high compressive strength filler material.
A method of repairing poles comprising the steps of:
- (a) cutting out the portion of poles to be repaired;
- (b) filling in said cut-out portion with a quick setting high compressive strength filler material;
- (c) cleaning the surface of the pole;
- (d) drilling holes into the pole and pumping a fumigant into the pole;
- (e) treating the cleaned surface with a bonding agent;
- (f) saturating woven glass mat strips with a composite resin;
- (g) applying saturated strips to the cleaned and treated surface to form a cylindrical encasement of desired thickness;
- and,
- (h) applying a ultraviolet resistant coating to the exterior of the cylindrical encasement.
A method of repairing utility poles in situ comprising the steps of:
- (a) excavating around the utility pole which is embedded in the ground to a pre-determined depth;
- (b) cutting out the portion of poles to be repaired;
- (c) filling in said cut-out portion with a quick setting high compressive strength filler material;
- (d) cleaning the surface of pole;
- (e) treat cleaned surface with bonding agent;
- (f) applying the saturated strips to the cleaned and treated surface to form a cylindrical encasement of desired thickness;
- and,
- (g) applying ultraviolet resistant coating to the exterior of the cylindrical encasement.
