Standard Practice for Direct Design of Precast Concrete Pipe for Jacking in
                Trenchless Construction

Abstract

Standard Practice for Direct Design of Precast Concrete Pipe for Jacking in Trenchless Construction covers design and recommended installation procedures for precast concrete pipe for jacking in trenchless construction. This standard addresses piping intended for the conveyance of sewage, industrial wastes, stormwater, and drainage, as well as for utilities and access ways. The design criteria include structural aspects, such as circumferential flexure, thrust, shear and radial tension strengths; crack width control; longitudinal thrust produced by jacking; and requirements for handling and installation.

The structural design of concrete pipe is based on a limits state design procedure that accounts for strength and serviceability criteria and is consistent with the procedures in Section 17 of the AASHTO Standard Specifications for Highway Bridges.
