Therefore, in this embodiment, the length in the lateral direction (vehicle length direction) of the apparatus body 12 is set to 1950 mm, and the length in the front-rear direction (vehicle width direction) is set to 1590 mm. Further, in this embodiment, the lateral length of the heating chamber 16 is 1640 mm, the longitudinal length thereof is 1530 mm, and the height thereof is 1460 mm.

  Then, with reference to FIG. 1 and FIG. 11, the construction method of rehabilitating the existing pipe 100 which has become obsolete using the heating device 10 and the pipe rehabilitating member 102 will be described.

  When renovating the existing pipe 100, first, the equipment and members necessary for construction including the heating device 10 are carried into the construction site. The pipe regenerating member 102 may be accommodated in advance in the heating chamber 16 in a factory or the like. When the heating apparatus 10 is carried into the construction site, the apparatus body 12 is carried on a loading platform of a conveyance vehicle in a state where external devices such as the steam generating device 64 and the hot air generating device 70 are removed. At this time, the apparatus body 12 is conveyed by the carrier as it is to the vicinity of a construction site where there is a wide road, and before the vehicle enters a narrow road such as a side road where the carrier can not enter Lower the main unit 12 Then, the operator pushes the apparatus body 12 by hand to move the apparatus body 12 into the construction site. As described above, since the apparatus body 12 can be moved without being loaded on the transport vehicle, the heating device 10 can be carried into a construction site where the road width is narrow and the transport vehicle is difficult to enter. Further, since the device body 12 can be moved by hand, adjustment of the installation position of the device body 12 can be easily performed. In addition, it is good to carry an external device etc. on a hand-push truck etc. and to carry in to a construction site suitably. In addition, since the steam generating device 64 is large-sized and labor for carrying by a hand-push truck or the like is required, the steam generating device 64 is installed near the construction site where the transport vehicle can enter, and the connection hose 62 is extended therefrom. It is also possible to correspond. However, when the transport vehicle can enter the construction site, the heating device 10 may be carried on the transport vehicle to the construction site.

  Next, as shown in FIG. 11, the heating device 10 is installed on the side of the vertical shaft 110 at the starting point. At this time, the apparatus main body 12 is disposed at a predetermined position, and external apparatuses such as the steam generating apparatus 64 and the hot air generating apparatus 70 are connected to the apparatus main body 12. In addition, on the end shaft 112 side, a winch 116 for winding the pulling wire 114 is installed.

  Subsequently, the pipe refreshing member 102 is heated and softened using the heating device 10. When heat-softening the pipe refreshing member 102, first, the rotary shaft 42 and the rotating table 44 are operated to rotate the pipe refreshing member 102. Subsequently, the steam generator 64 is operated to supply steam to the inner surface side of the pipe renewal member 102 through the steam pipe 56 and the like. Further, the hot air generator 70 is operated to supply the hot air from the connection port 66 to the inside of the heating chamber 16 and heat the inside of the heating chamber 16 with the hot air. Then, the pipe renewal member 102 is heated for a predetermined time at a predetermined atmospheric temperature (for example, 80 to 110 ° C.). Further, when heating and softening the pipe retreading member 102, the ceiling material 24 may be slightly shifted to form an exhaust port (not shown) in the heating chamber 16.

  When the pipe renewal member 102 is sufficiently heated and softened, the side wall member 22 opposed to the drawer guide 72 is slid upward and pulled up to a predetermined position, so that the outlet of the pipe renewal member 102 is made in the lower side wall of the heating chamber 16. Form. The raised side wall member 22 may be held at a predetermined position by supporting its lower end with a pin inserted in the vertical guide rail 30, for example. Thereafter, the pipe renewal member 102 is pulled out from the outlet, and the pipe renewal member 102 is inserted into the existing pipe 100 through the withdrawal guide 72. When inserting the pipe regenerating member 102 into the existing pipe 100, the pull wire 114 is inserted into the existing pipe 100 from the end shaft 112 side, and the pull wire 114 is connected to the tip of the pipe regenerating member 102. Thereafter, by winding the pull wire 114 with the winch 116, the pipe renewal member 102 is drawn into the existing pipe 100.

  When the tip end of the pipe member 102 reaches the vertical shaft 112, both ends of the pipe member 102 are cut, metal fittings for expansion and the like are attached thereto, and the pipe end of the pipe member 102 is sealed. Then, steam is supplied into the pipe renewing member 102 using the steam generator 64 to heat the pipe renewing member 102 and apply an internal pressure. Then, the cross-sectional shape of the pipe regenerating member 102 is restored to a true circular shape or a substantially true circular shape, and the entire outer peripheral surface of the tube regenerating member 102 is in close contact with the entire inner peripheral surface of the existing pipe 100.

  Thereafter, in a state where the internal pressure is maintained, cooling air is supplied from the cooling nozzle or the like into the pipe refreshing member 102 to cool the pipe refreshing member 102. After cooling, the pressurized air is exhausted from within the pipe renewal member 102, and the post-treatment is appropriately performed, whereby the rehabilitation of the existing pipe 100 using the pipe renewal member 102 is completed.

  As described above, according to this embodiment, since the base portion 14 is provided with the plurality of wheels 18, the main body 12 of the heating device 10 can be moved by hand pressing without being placed on the carrier. Therefore, the heating device 10 can be carried into a construction site where the width of the road is narrow and the transport vehicle is difficult to enter.

  Further, according to this embodiment, since the ceiling material 24 is detachably provided on the side wall material 22 so as to form an opening for putting the pipe renewal member 102 into the heating chamber 16, the side wall is left. In the state, the pipe renewal member 102 can be put into the heating chamber 16. That is, since there is no need to remove the side wall at the time of mounting the pipe regenerating member 102, the mounting operation of the pipe regenerating member 102 into the heating chamber 16 is simplified.

  In addition, in the above-mentioned Example, although the pipe regeneration member 102 is made into the diameter reduction shape of a cross-sectional substantially wedge shape, the diameter reduction shape and winding appearance of the pipe regeneration member 102 are not specifically limited. For example, it may be a diameter-reduced shape that is folded by folding, or may be a diameter-reduced shape that has a substantially heart-shaped cross section in which a part in the circumferential direction is pressed.

  Further, in the above-described embodiment, when the pipe renewing member 102 is installed in the heating chamber 16, the axis for rotating the pipe renewing member 102 extends in the longitudinal direction (that is, the pipe renewing member 102 is rotated laterally). However, the axis for rotating the pipe regeneration member 102 may extend in the lateral direction (that is, the pipe regeneration member 102 is rotated in the longitudinal direction).

  Furthermore, in the above-described embodiment, the vapor is supplied to the inner surface side of the pipe revetment member 102. Alternatively, or together with this, the vapor is supplied from the outer surface side of the pipe regenerating member 102 to the inside of the heating chamber 16. It may be supplied. Moreover, it is not necessary to necessarily provide both a steam supply part and a hot air supply part, and it is sufficient to provide only any one.

  Furthermore, in the above-described embodiment, the side walls of the heating chamber 16 and each wall of the top wall are constituted by two or three wall members 22 and 24, but the number of divisions of each wall can be changed appropriately. For example, each wall can also be configured of a single wall material 22, 24. In addition, the specific configuration such as the number and the arrangement of the frames 26 and 28 of the heating chamber 16 can be appropriately changed.

  Moreover, in the above-mentioned Example, although the ceiling material 24 was provided detachably with respect to the ceiling frame 28, it is not limited to this.
