FUSIBLE POLYVINYLCHLORIDE PIPE: WATER AND WASTEWATER INFRASTRUCTURE CONSTRUCTION AND REHABILITATION REDEFINED

摘要

The development of fusible polyvinylchloride pipe with fully restrained, gasketless,thermally butt-fused joints creates a pipe system that has the same strength at the jointas the rest of the pipe. This pipe and joining technology create a fully monolithicsystem that can be used in conventional direct bury installations as well as cuttingedge trenchless applications; including horizontal directional drilling (HDD),sliplining and pipe bursting. This technology offers some unique alternate solutions tothe ongoing concerns of aging water and wastewater infrastructure, life cycle costs ofnew and rehabilitation installations, and installations within constrained project sites.This paper will focus on the specific technology for this type of jointing of PVC pipeand document the benefits and considerations of this technology for use in the waterand wastewater industries. A recent project case study that has utilized thistechnology will also be reviewed.
