PURPOSE:To easily connect the side edge parts of a strip like material main body by fitting the ridges formed to a fitting strip like material in the adjacent fitting parts parallelly provided to the side edge parts of the strip like material main body within an existing pipe to bond the same to the fitting parts and bonding the strip like material main body to the inner peripheral surface of the existing pipe. CONSTITUTION:The inner peripheral surface of an existing pipe is lined with a strip like material main body 10 and a fitting strip like material 20. The strip like material main body 10 having fitting parts 13 bent outwardly from the edge parts of the main body after the rising of the existing pipe and having a shape returning to the side opposite to the inner peripheral surface of the existing pipe at the leading ends thereof formed to both side edge parts thereof in a lateral direction is spirally bonded to the inner peripheral surface of the existing pipe. The ridges 22a, 22b longitudinally formed to the fitting strip like material 20 are fitted in the adjacent fitting parts 13 parallelly provided to the side edge parts of the strip like material main body 10 within the existing pipe to be bonded thereto. |
