NON-EXCAVATION LINING METHOD FOR PIPING

PROBLEM TO BE SOLVED: To provide a method which can all together line a supply pipe having branch pipes. SOLUTION: A non-excavation lining method for piping includes a first process of dividing a main pipe 1 into a road side main pipe 1b and a site side main pipe 1a, a second process of pressure-fee...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method which can all together line a supply pipe having branch pipes. SOLUTION: A non-excavation lining method for piping includes a first process of dividing a main pipe 1 into a road side main pipe 1b and a site side main pipe 1a, a second process of pressure-feeding a lining means 3 to a branch pipe 9a, a third process of air stream transfer-lining the inner surface of a branch pipe 8a, a fourth process of lining the inner surface of the side main pipe 1a when the lining means 3 is returned to a main pipe opening 1d by pressure-feeding from a branch pipe 9a opening, a fifth process of air stream transfer-lining the branch pipe 9a, a sixth process of removing the blocking of a main pipe branch part produced in the fourth process, and a seventh process of liquid phase-lining the road side main pipe 1, and the entire supply pipe 1 is lined.
