ライニング施工が実質上終了される。In FIG. 10, the starting manhole side of the spirally joined tubular body E 'is substantially fixed in the pipe, and the feed speed of the band-like member of the joining mechanism by the hydraulic motor is v,
Assuming that the feeding direction is θ with respect to the circumferential direction of the tubular body, the pipe-making machine is moved forward at a speed v ′ regulated by v and θ, and the length of the spirally joined tubular body is increased at the same speed v ′ by the movement. Will be increased. Also, the outer roller 21 'and the inner roller 22' of the joining mechanism 2 'are driven by the hydraulic motor 25'.
Is transmitted to the feeding strip-shaped member D ′, and in FIG. 8, the lined spiral-joined tubular body E ′ is fixed to this transmission force, so that the pipe-making machine B ′ is fixed.

When the outer diameter of the tubular body is smaller than the inner diameter of the culvert and a gap ΔG is left between the outer surface of the lining tubular body and the inner surface of the culvert, the inner lining of the lining tubular body has an ideal lining when the gap is zero. It becomes considerably smaller than the inside diameter, and a considerable decrease in the cross-sectional area of the flow passage of the rehabilitation pipe is inevitable.

Although the gap ΔG between the outer surface of the lining tubular body and the inner surface of the sewer is made substantially zero, the balance between the shearing force and the joining force is difficult, and implementation is difficult.

As shown in the above, sufficient sealing properties are exhibited by the self-sealing action of the lip packing a against the internal water pressure and by the self-sealing action of the lip packing b against the external water pressure. Water leakage blocking performance can be guaranteed. Actually, when a water pressure test was conducted by lining the inner surface of a reinforced concrete pipe having an inner diameter of 1100 mmφ with the lining member of the above embodiment according to claim 1, water leakage occurred even at an inner water pressure of 0.4 Mpa × 3 minutes against the inner water pressure.

In this case, the frictional force m '(corresponding to the rotational braking force m') acting between the pipe making machine and the inner surface of the sewer is small, and the equation (6) is not satisfied. I can't let it. Then, it can be implemented as follows. (1) The tubular body is lined by a predetermined length L by feeding the lining member, spirally winding, joining the slidable joining portion, and rotating the tube making machine. If the length L is too long, it is difficult to uniformly perform the next diameter expansion, and it is preferable that L be about several meters. Further, for example, in the case of a sewer having an inner diameter of 1000 mmφ, the inner diameter of the tubular body is 7 mm.
It is preferable to set it to 00 to 900 mmφ. (2) Next, the movement of the pipe making machine is forcibly stopped, and in this state, the lining member is fed, spirally wound, and the slidable joining portion is joined to attach the lining member to the already-lined tubular body. The diameter of the lining tubular body is increased by feeding it spirally (usually, the diameter is increased until it comes into contact with the inner surface of the sewer). At this stage, since the moving amount of the tube making machine is 0, there is no increase in the length of the lining tubular body, and the lining member to be fed is used for expanding the diameter of the existing lining tubular body. (3) Further, (1) and (2) are performed, and thereafter, these steps are repeated to line the inside of the pipe with a tubular body having an enlarged diameter.

ング用部材。5. A tubing machine which continuously feeds a long strip-shaped member having slidable joining portions at both edges by a pipe-making machine and joins the slidable joining portions in a spiral shape. A lining member that is formed into a tubular body by being wound around, and the tubular body is expanded by sliding the slidable joint with a belt-like member feeding force to line the inside of the sewer, The slidable joint portion is provided with slidability so that the seal member at the local interface can be compressed by the tension of the local interface due to the expansion of the expandable member into the gap in the slidable joint portion communicating with the inside and outside of the tubular body. A member for lining the inner surface of a sewer characterized by having an unexpanded inflatable member and a seal member having a thickness that can be held.
