摘要： The invention provides a tube for use as part of a structural support pole, and a method for manufacturing a tube, comprising a plurality of tube perimeter sections, wherein each tube perimeter section of the first plurality of tube perimeter sections is formed by pultrusion, each tube perimeter section of the first plurality of tube perimeter sections having the same pultrusion cross-sectional shape, and wherein each tube perimeter section comprises: an outer surface; an inner surface; a side surface; and a cavity between the inner surface and the outer surface, wherein the cavity extends through the tube perimeter section. The side surface is adapted to be fastened to an adjacent side surface of an adjacent tube perimeter section, thereby to form an annular arrangement of tube perimeter sections. The tube further comprises a first filament, wherein the first filament is wound about the outer surfaces of the first plurality of tube perimeter sections arranged in an annular arrangement.

摘要： An apparatus for installing cables or pipes in tunnels comprises a motorised vehicle. A cable/pipe positioning arm is at each end of the vehicle, which is controllable to move a cable/pipe from a temporary installation position to a final installation position. One or more cable/pipe sagging arms are spaced from the positioning arm at the other end of the vehicle which are controllable to apply a desired amount of sagging to a length of cable/pipe between adjacent final installation positions. The apparatus can be driven along the cable/pipe performing the positioning and sagging in a single sequence and in either direction.
