<p>A composite dowel structure and related methods (Fig. 1) are provided, for preparing, repairing and/or reinforcing existing hollow support structures, e.g. light poles made of steel, iron, or fiberglass, especially support structures that have lost tensile strength due to corrosion or other types of deterioration. The methods are particularly useful in preparing, repairing and/or reinforcing a hollow support structure, by forming a composite dowel structure, in situ, in the hollow support structure.</p> |
