COVERING MATERIAL FOR PARTIAL REPAIR OF EXISTING PIPE

PROBLEM TO BE SOLVED: To provide a covering material for partial repair, enables cut-off performance to be maintained by preventing formation of a gap between the inner face of an existing pipe and a cylindrical part, even in the case of a deformed existing pipe.SOLUTION: A covering material 10 made...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a covering material for partial repair, enables cut-off performance to be maintained by preventing formation of a gap between the inner face of an existing pipe and a cylindrical part, even in the case of a deformed existing pipe.SOLUTION: A covering material 10 made of hardening resin for partial repair having cylindrical parts 12 and 14 for covering a repair target spot of an existing underground pipe from the inner side includes an elastic member 16 which covers the whole circumference of the outer peripheral surface of at least the marginal region of the cylindrical part and intervenes in a compressed state between the existing pipe and the cylindrical part in the covering state. The elastic member 16 has a void structure.
