<p>PURPOSE:To enable the repair having excellent workability of connection at an execution field and security by forming a kit with a partitioning wall member, in which a roof piece formed into a shape along a perforated pipe is provided, and a gutter-formed first enclosing member for enclosing the roof piece and the perforated pipe and a gutter-formed second enclosing member. CONSTITUTION:A repairing kit consists of a partitioning member 21, a first enclosing member 31 and a second enclosing member 41. The partitioning member 21 consists of partitioning wall parts 21a, 21b and a roof pieces 22,.... The first enclosing member 31 is a cylindrical member divided into two in the axial direction, and are arranged so as to enclose end surfaces of the partitioning member 21 and abutment parts Y, Y of a residual tube 1a. Furthermore, the second enclosing member 41 is a cylindrical member divided into two in the axial direction, and has the inner peripheral surface having a curvature as same as the outer peripheral surface of the first enclosing member 31. As a result, a perforated pipe can be repaired securely with a small number of parts.</p> |
