Construction Productivity Advancement Research (CPAR) Program. Guidelines forTrenchless Technology: Cured-in-Place Pipe (CIPP), Fold-and-Formed Pipe (FFP), Mini-Horizontal Directional Drilling (Mini-HDD), and Microtunneling

摘要

These guidelines mark the completion of the Construction Productivity AdvancementResearch (CPAR) project 'Trenchless Construction: Evaluation of Methods and Materials to Install and Rehabilitate Underground Utilities.' CPAR is a cost-shared U.S. Army Corps of Engineers and construction industry research program. This 3-year project was conducted by the U.S. Army Engineer Waterways Experiment Station and the Trenchless Technology Center at Louisiana Tech University. The overall objective of this study was to develop guidelines that owners, engineers, and contractors could use to evaluate and select appropriate trenchless methods and equipment for their project requirements and site conditions. The guidelines focus on the three major elements of trenchless technology investigated in this study: rehabilitation of existing pipelines using cured-in-place (CIPP) and fold-
