Abstract:
The purpose of the present invention is to provide a pipe inner-layer structure which exhibits long-term durability even after work completion, and which simplifies installation work by dispensing with labour related to the assembly of component members including an inner surface material, while enabling the inner surface material to be accurately disposed. Accordingly, the present invention comprises: fixed members (2) provided along an inner peripheral surface of a pre-installed pipe (1) with spaces therebetween in the pipe-axial direction of the pre-installed pipe (1); connection members (3) which are provided to the fixed members (2), and which are each provided with a first fitting member (31) having an inner surface material (4) fitted thereto, and a second fitting member (32) for attaching to the fixed members (2); and the band-like inner surface material (4) which is fitted to the first fitting members (31) of the connection members (3), and which is provided across adjacent fixed members (2) in the pipe-axial direction of the pre-installed pipe (1). The connection members (3) are divided, configured, and provided to the fixed members (2) via the second fitting members (32) with which each of the connection members (3) is provided.
