Abstract

Abstract The joinder of ducting such as underground systems of multi-tube form, comprised of a coupler assembly receiving the complementary ends of one or more continuing duct sections and bonded thereto and the sections thereby connected together by means of liquid material hydraulically applied under pressure to enter an annulus around each duct to be coupled, and wherein the application of and solidification of said material purges each said annulus while adhereing to bond the coupler and ducts and thereby hermetically sealing each joinder; and the system being characterized by its adaptability to an array consisting of a multiplicity of ducts cooperatively arranged by means of a saddle having a manifold simultaneously distributing said liquid material to the coupler connections; there being process support means and a kit involved in the method of coupling by which the bonding material is hydraulically injected with heat applied as required.
