摘要

PURPOSE: To provide the subject lining material having a smooth inner peripheral surface, ensuring the inner flow-down capacity and high strength of an aqueduct and capable of smoothing aqueduct regenerating work. ;CONSTITUTION: A tubular lining material is drawn into an existing aqueduct in an uncured state and the curable resin 4 of the lining material is cured in such a state that the lining material 1 is pressed to the inner surface of the existing aqueduct by compressed air supplied into the lining material. The lining material 1 has a tubular resin layer 5 containing the curable resin 4 in an uncured state, the inside and outside membranes 6, 7 applied to both inner and outer surfaces of the resin layer 5 and a plurality of reinforcing materials 8 embedded in the resin layer 5 almost in parallel to the drawing-in direction.;COPYRIGHT: (C)1996,JPO
