Abstract
The present disclosure provides polymer composite helical anchors/piles comprising a polymer composite shaft and at least one polymer composite helical plate extending laterally from the polymer composite shaft.
Claims8
A helical anchor/pile comprising:
- a polymer composite shaft having an end portion and a head portion, wherein the head portion is configured to connect to at least one of an extension and a thimble eyelet;
- and
- at least one helical plate attached at the end portion of the shaft, wherein the at least one helical plate is formed from at least one of a polymer composite material and metal, the at least one helical plate comprising a metal inner circumferential helical plate and a polymer composite outer circumferential helical plate, and wherein the polymer composite outer circumferential helical plate extends over at least a portion of the metal inner circumferential helical plate.
A helical anchor/pile comprising:
- a polymer composite shaft having an end portion and a head portion, wherein the head portion is configured to connect to at least one of an extension and a thimble eyelet;
- and
- at least one helical plate attached at the end portion of the shaft, and further comprising polymer-impregnated fiber strands covering at least one surface of the helical plate, wherein the polymer-impregnated fiber strands comprise an interwoven mat of fiber strands.
