20090110488 | Method of splicing a pair of foundation piles - A method of coaxially splicing a pair of tubular foundation piles in an end-to-end relationship includes the step of constructing a tubular splice from a resilient material, the tubular splice having the same outer diameter as the pair of foundation piles and being shaped to define a longitudinal slit which extends the entirety of its length. A strap is cinched tightly around the splice which renders its outer diameter less than the inner diameter of the pair of foundation piles. Each end of the compressed splice is then inserted into an adhesive coated end of a corresponding foundation pile. With the pair of foundation piles telescopingly mounted over the compressed splice, the cinched strap is removed which causes the splice to resiliently expand radially outward and thinly spread the adhesive. The foundation piles are then preferably drawn together and the adhesive is allowed to cure. | 04-30-2009 |
