<p>PURPOSE:To repair an abraded part of a pneumatic refuse transporting pipe from the inner side even when the abraded part is buried in the earth. CONSTITUTION:In making a reinforcement of an abraded part 16 by fitting a patch 1 with a curved surface corresponding to the inner surface of a pipe onto the inner wall abraded part 16 of a refuse transporting pipe 15, an inner pipe having the outer diameter approximately equal to the inner diameter of the transporting pipe 15 is formed by leaving a slight clearance between the representative presser plates 2a, 2b by adding two presser plates 2a, 2b having the curved surfaces corresponding to the inner surface of the pipe in the circumferential direction at the right and the left sides of the patch 1, and the patch 1 is fixed by the presser plates 2a, 2b on the respective sides by inserting a wedge 3 into the clearance of the representative presser plates 2a, 2b in the axial direction of the pipe.</p> |
