ABSTRACT:
An internally reinforced extruded plastic pipe which is adapted for use as an underground infiltration, collection, or transport conduit for liquids and gases. The pipe is provided with at least one integral reinforcing stem and the critical mode of failure is buckling rather than deflection. The pipe is not dependent upon surrounding backfill for lateral support as with conventional pipe or conventional reinforced pipe. The same amount of plastic is usable per lineal unit as is used in comparable conventional pipe sizes, however, the cross-section is redistributed, which achieves greater loading capacity.
