〜１５０３７号公報参照）を提案した。The lining of the inner surface of the pipe is usually about 80 to 150 m long.
Since it is implemented as a span, in many cases branch pipes are attached at several locations to more than ten locations in the middle of the pipeline. Since the pipe opening of this branch pipe will be blocked by tube lining, it is necessary to open the pipe opening after construction.
JOL, such as opening device li (for example, Utility Model Act 60

）施工への適用が危ぶまれている。However, when tube lining is performed on the inner surface of the conduit by applying the tube reversal insertion method, as shown in Figures 7 and 8, the inner surface of the conduit (a) and the tube (d) lined therewith are separated. The adhesive (C) squeezed out from between the tube (tl) is deposited on the inverted part (d) of the tube (tl),
It has been found that when the branch pipe <b> passes through, it penetrates deeper than the pipe opening (b□), for example to a depth exceeding 20wIR, depending on the Nikkei of the branch pipe, making it difficult to open the pipe opening after the lining process. Conduit lining using tube reversal insertion method/

The elastic pad (7) is advanced, and the sealing material (9) with adhesive (9a) (see Fig. 6) at position a is placed on the upper surface of the elastic pad (7) at the pipe opening (b).
If it is attached to the inner surface of the pipe (a) containing the pipe (□), the pipe opening (b□) can be blocked. This occlusion situation is illustrated in FIG. Sealing material (9) as shown in Figure 2
The pad (7) on which it is placed is deformed due to its elasticity,
This deformability allows the sealing material (9) to be stably and reliably attached to the inner surface of the pipe. A link-shaped material is used as the sealing material (9), and this is applied to pipes including branch pipe openings (b work) using a pipe construction machine such as that described in JP-A No. 57-57991. Path (a) may be affixed to the entire inner circumference.

During this tube lining construction, as the tube (→) is reversed and inserted, the adhesive ([) will accumulate in the forward direction of the reversed section (d work).
The pipe port (b□) of the branch pipe (b) is already sealed with the sealing material (9), so the pipe port (b□) of the adhesive part <1>
Such tube lining can be carried out without intrusion into the interior. Although the top view shows the case where the adhesive (C) is applied to the tube (b) side, it may be applied to the inner surface of the conduit (-) in advance.
