<p>PROBLEM TO BE SOLVED: To eliminate pressureproofing countermeasures to assemble timbering, to apply hydraulic pressure, etc., at the time of injecting a back-filling material and to give high strength by applying it to an existing pipe dmagaed seriously due to corrosion, etc., even by using a back-filling material comparatively low in strength and inexpensive. SOLUTION: Strength of a repairing member 1 itself is remarkably improved in comparison with a conventional one, it endures injection pressure of the back-filling material for itself and strength of a conduit after repairing is shared by connecting each of repairing member units 1 in the axial direction while the cylindrical repairing member 1 made by having a resin made surface material and reinforcing rings 12a, 12b integrated on its outer periphery by forming a resin plate 11 brought in from a manhole cylindrical in the manhole or in the existing pipe and assembling a reinforcing member made of a high rigidity material brought in from the manhole in the same way in a ring shape along its outer periphery while integrating it against an outer periphery of the resin plate 11 formed cylindrical.</p> |
