Applications
Concrete Jacking Pipe is used for the following applications:
 |
Highway culverts
|
|
Railroad culverts
|
|
Aircraft runway crossings
|
|
Deep combined sewer overflow systems

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. |
