Thrust Restraint of Buried Ductile Iron Pipe

by Randall C. Conner, American Cast Iron Pipe Co, Birmingham, AL, USA,



Document Type: Proceeding Paper

Part of: Pipeline Infrastructure

Abstract:

It is the intent of this paper to present current state of the art thrust restraint design, present a basis for calculating required lengths of restraint, and to offer some practical suggestions based on full-size field tests, model tests, experience, and some measure of common sense. While understanding of the design of many varied forms of concrete reaction blocking is essential to the design Engineer, this field is in general well developed and well understood. Therefore, this paper is for the most part devoted to a discussion of systems involving restrained joint pipe, which admittedly can involve much more complicated concerns.
