Abstract

A laddertube (10) for an underground raise is described having an elongate tube (12) made of a suitably rigid plastics material and adapted to be received in the raise. The tube (12) has a series of steps (14) moulded into an interior side wall thereof so as to form a ladder extending substantially the full length of the tube (12). Part only of the circumference of one end of the tube (12) is formed with an inside offset male edge (30) whereas the remainder of the one end is formed with a non-offset male edge (32). Part only of the circumference of the other end of the tube is formed with an outside offset female edge (34) whereas the remainder of the other end is formed with a non-offset female edge (36). In use, the inside offset male edge (30) can be received within the non-offset female edge (36) on the other end of an adjoining tube of identical design, and the outside offset female edge (34) can be received around the non-offset male edge (32) on the one end of the adjoining tube when the tubes are joined end to end. Amongst other advantages, this ensures that part of an internal wall of adjoining tubes is substantially smooth in the region of the join when the tubes are joined end to end.
