ASCE 27-17 PDF Download

ASCE 27-17 is a standard practice developed by the American Society of Civil Engineers (ASCE) addressing the direct design of precast concrete pipe for jacking in trenchless construction. The standard provides guidance for designing and installing precast concrete pipe using jacking techniques, which involves pushing or pulling the pipe into place without excavation.

The standard covers various types of piping applications including sewage, industrial wastes, stormwater, drainage, utilities, and access ways. It offers design and analysis methods that consider the interaction between the pipe and the surrounding soil or grout envelope. This helps determine the longitudinal loads that occur during jacking, as well as transverse pressure distributions and circumferential moment, thrust, and shear in the pipe wall.

One key aspect covered in the standard is the calculation of the required reinforcement in the pipe wall. This ensures the pipe is structurally sound and can withstand the forces exerted during jacking. The standard also provides guidance on manufacturing suitable pipe, managing jacking operations, and estimating the required jacking force.

ASCE 27-17 is a revised version of ASCE 27-00 and includes updates to align with the latest ASTM International and American Concrete Pipe Association (ACPA) documents. It can be used as a reference in project specifications for jacking in trenchless installations and follows a limit state design procedure consistent with the procedures outlined in the AASHTO Standard Specifications for Highway Bridges.
