Concrete pipe is the ideal jacking pipe due to its strength, rigidity and durability.
Applications
Concrete Jacking Pipe is used for the following applications:
Highway culverts
Railroad culverts
Aircraft runway crossings
Deep combined sewer overflow systems
To avoid surface disruption typical of open cut construction
Waterway crossings
Sizes/Shapes
Circular pipe, elliptical pipe, arch pipe and box culverts are all suitable for jacking. The pipe or box to be jacked must be large enough to permit man-entry. Typically, 30-inch diameter is the smallest practical circular pipe and 3-foot-by-3-foot the smallest practical box section.
Joints
Joints suitable for Jacking Pipe include:
Tongue and groove
Confined O-ring — flush wall
Single-offset joint — flush wall
Banded-bell double rubber gasket
