Abstract
Prefabricated concrete pipe encasements are disclosed for stabilizing underground conduit systems from movement caused by flotation, back filling or settling. In one embodiment, a sewer chimney includes a plastic riser connected between a tee-fitting in a sewer main and a cap block at a branch service line. At least one pipe encasement and a prefabricated concrete base encircles the riser for maintaining alignment with the tee-fitting. In other embodiments the pipe encasement encircles a generally horizontal pipe line.
