METHOD AND APPARATUS FOR LINING OF PIPES

摘要

A distributor head for throwing mortar onto the wall of a pipe (12) being lined. A set of inner rotating vanes (56) throw the mortar onto an outwardly flared conical surface (40 and the mortar travels along the surface (40) to the outer vanes (48) on its outer edge from which the mortar is thrown in a high velocity, dense stream against the pipe wall. The inner vanes are individually and releaseably fitted into a collar (60) at the inner edge of the flared conical surface.
