Abstract
A method for utilizing a unique multi-chambered conduit insert for converting a single chambered conduit into a multi-chambered conduit. In particular, the conduit insert includes a plurality of cooperating longitudinally extending walls defining a plurality of parallel spaced apart coextensive chambers. The outer wall of each chamber which is adjacent the inner supporting surface of the single chambered conduit has a configuration wherein, if the outer wall contacts the inner conduit surface when the conduit insert is inserted within the conduit, such contact is line-to-line contact. This construction results in minimal contact of the insert with the interior wall of the existing conduit and enables the multi-chambered conduit insert to be fed into the existing conduit with the expenditure of minimal energy. In the method of the present invention, two individual conduit inserts are placed in back-to-back relationship to form an insert assembly which is subsequently inserted into the single chambered conduit.
