Splicing Precast Prestressed Concrete Piles

摘要

align="left">The Boston Edison Company in Everett, Massachusetts, was looking for an economical, easy-to-use yet strong splice for precast prestressed concrete piles. The company decided to use a splicing? technique that was originally developed in Sweden. Because there is a 60 ft (18.3 m) maximum length allowed on the highways in Sweden, it was imperative that a reliable splicing technique be developed in that country. Indeed, most concrete piles in Sweden are spliced. Swedish contractors, therefore, prefer to purchase smaller, less costly equipment while investing more money in shorter piles and quality splices.? In their opinion, the piles and splices are what is important, and they should be easy to use at the job site.
