摘要

The present invention relates to a branch pipe sealing pack to repair a drain pipe and a repairing device for a drain pipe using the same and, more specifically, relates to a branch pipe sealing pack to repair a drain pipe capable of repairing the drain pipe while a branch pipe is sealed during a repairing process of a crack of the drain pipe to which the branch pipe is connected, and a repairing device for the drain pipe using the same. The branch pipe sealing pack to repair the drain pipe comprises: a sealing tube (10) capable of being expanded along a circumference while gas is injected therein, wherein at least a part of the sealing tube (10) is formed of an expandable material; a contact pad (17) having a curvature radius in which a contact surface coming in contact with the circumference of the drain pipe corresponds to the circumference of the drain pipe, wherein an end of the sealing tube (10) is connected to the contact pad (17); and an injection nozzle (N1, N2) formed on the contact surface. A supply path connected to the injection nozzle (N1, N2) is formed in the contact pad (17), and the contact surface has flexibility.;COPYRIGHT KIPO 2018
