US 10,343,307 B2 · Method of making interlocking joint for pile encapsulation jackets

Abstract

Embodiments provide a method for forming a groove on a pile encapsulation jacket to form an interlocking joint on the pile encapsulation jacket. A spacer may be used to form the groove. First, a pile jacket laminate is formed on a mandrel surface. The pile jacket laminate may be partially cured to have a solid but sticky surface. The spacer may be placed on the pile jacket laminate. An additional layer of laminate may be formed on at least a portion of the pile jacket laminate and at least a portion of the spacer. The entire structure may be cured and the spacer may be removed. A groove is formed between the pile jacket laminate and the additional layer of laminate at a space previously occupied by the spacer. The groove has the same width as the portion of the spacer that was covered with the additional layer of laminate.
