ABSTRACT:
The invention relates to a pipe system comprising four pipes or tubes each with external corrugations. The pipes also have an end sleeve or connector joint. As in the first embodiment, the pipes of the system are supported in a desired array by an initially separate support, comprising in use base element or part, an intermediate or middle, in use, cruciform element or part and in use upper element or part. The upper part is shown cut away to show the pipes in position. The parts of the support are bound together by a shrink-wrapped film, e.g. of polyethylene, and can be delivered to a building site and laid in a trench without the need to import on the site expensive gravel, sand, soil or the like. Material removed from the trench is used as the back fill.
