<p>According to the present invention, disclosed is a non-excavating pipe repair member which includes: a cylindrical sleeve; a hooking member which is fixed to the sleeve and has a hooking protrusion; and a guide belt which is installed to surround an outer surface of the sleeve, and has a hooking hole corresponding to the hooking protrusion. The guide belt is configured so that the width of a blocked part formed between two hooking holes is smaller than the width of the hooking hole and thus a hooking protrusion is not located in the blocked part and is inserted into the hooking hole well, and the hooking protrusion comprises a first hooking protrusion and a second hooking protrusion. The non-excavating pipe repair member according to the present invention prevents a combining force of the guide belt from being loosened when the sleeve moves and is expanded, and thus has improved quality and excellent construct ability, because the hooking state of the hooking member is maintained by inserting one of the first hooking protrusion or the second hooking protrusion of the hooking member fixed to the sleeve is inserted accurately into the hooking hole of the guide belt when the sleeve is rolled in a cylindrical shape.</p> |
