Abstract

A method and apparatus for coupling pipe, and installing coupled pipe in a trenchless installation, the pipe being adapted for use as a watermain or the like. Lengths of watermain pipe are provided with a bell at each end, and connecting nipples adapted to be received within opposing bells, to effect a fluid-tight seal. As lengths of watermain are urged into a trenchless tunnel, opposing bell-end faces withstand the force being exerted on the pipe sections, so that damage is avoided and a sealed underground pipe installation is economically and quickly effected.
