Abstract

PURPOSE: In case when the junction plug is installed to the double tube, the stopper is inserted in the spaced part between the existing tube and the flexible tube and the change by heat shrinkage of the flexible tube on the existing tube already fitted is prevented.
CONSTITUTION: The specified outer position of an existing tube 1, made of the cast iron in the concentrically double structure, is broken to expose a flexible tube 2. Then, a rubber packing 3 is inerted to the spaced part between the existing tube 1 and the flexible tube 2 from the broken portion of the existing tube 1. After that, a split type stopper 4 is also inserted to fix it to the flexible tube 2. Successively a juction plug 5 is connected by the designated means to the exposed part of the flexible tube 2. When if necessary the cement milk is put between the existing tube 1 and the flexible tube 2 and also after piping the connected tube, sand so on is embedded. Then, the operation is finished. Thus, althought the flexible tube 2 to be placed inside the outer tube is the one which has a large heat shrinkage, the flexible tube 2 adjacent to the junction plug 5 is firmly maintained keeping certain interval with the existing tube 1.
