Hollow tube-shaped drainage drainage element and process for drainage drainage

摘要

Sewer lining comprising a plurality of hollow tubular lining members (2,3) and a method of lining a sewer with such members. Lining members (2,3) are particularly adapted for use in the lining of non-man-entry sewers by means of resilient bands (6,8) sealing over the engagement between adjacent lining members. Lining members have a spigot (2) at one end and a socket (3) at the other. Tapering of the socket (3) and lining of it with a deformable element (6,8) serves to locate the spigot and provide an internal seal in use. IMAGE
