METHOD OF REPAIRING SEVER PIPE BY NON- EXCAVATION
The present invention relates to a non-excavation overall repairing method for a sewer pipe. The present invention recycles a condensate generated when a gasified steam used to stiffen a stiffener to be used as a heat source to remove the condensate, and improve heat efficiency when an old pipe is repaired by the non-excavation method using a tube-shaped stiffener. The present invention absorbs the condensate generated inside the stiffener using the condensate and a steam recovery means, and a portion of the steam increases an inner pressure while stiffening the stiffener using the steam and enables the condensate and the stiffener to circulate to a water tank supplying water to a boiler in order to improve heat efficiency and remove the condensate at an early stage. As such, the present invention removes a stiffening delay and a non-stiffening of the stiffener to improve constructability and can be installed with a small amount of water due to condensate circulation having the heat source, and can minimize equipment required for the method.
