摘要

A bent pipe lining method which can get rid of bulky creases of the liner commonly formed at the bends of the pipe, and the method is characterized by a use of a flat belt that is hitched to the sewn-end of the liner bag, which pulls the flat belt inside itself as it is everted into the bent pipe; when the liner bag is hardened the flat belt is kept stretched so as to keep the bulky creases compressed and bent flatly.
