A method for lining a bent pipe

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, which is characterized by the use of a flat belt (8) that is attached to the sewn-end of the liner bag (1), which pulls the flat belt inside itself as it is everted into the bent pipe (21); when the liner bag is hardened the flat belt is kept stretched so as to keep the bulky creases compressed and bent flatly. <IMAGE>
