  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, prior to explaining the method for producing a rehabilitated pipe according to the present invention, the band member 100 with a reinforcing material, the pipe making apparatus 1 and the curl correction apparatus 10 to be used will be described.

  As shown in FIG. 1, the reinforcing band member 100 includes a synthetic resin having flexibility, for example, a synthetic resin band member 110 such as polyethylene and polypropylene, and a metal embedded in the synthetic resin band member 110. It is comprised from metal reinforcements 120, such as a board, for example, a steel plate.

  The synthetic resin strip member 110 includes a strip plate-like substrate 111 and a plurality of ribs (three in the embodiment) having an I-shaped cross-section standing on the back side of the substrate 111 perpendicular to the substrate 111. 112. Then, at one side edge of the substrate 111, the other side edge of the substrate 111 in the adjacent synthetic resin belt-shaped member 110 can be disposed on the back side by the thickness of the substrate 111. The stepped portion 113 is formed.

  The metal reinforcing member 120 is formed in a flat plate shape and is embedded in each rib 112 of the synthetic resin band member 110 over the entire length thereof.

  Such a band member 100 with a reinforcing material is formed by extruding a synthetic resin band member 110 (in this case, the rib 112 has two parallel ridges with a gap corresponding to the thickness of the metal reinforcing material 120). The metal reinforcing material 120 is introduced into the rib 112 (the gap between the two raised portions) over the entire length thereof, and then extruded to the top of the rib 112 to form the metal reinforcing material 120. It is manufactured by encapsulating.

  The manufactured belt-like member 100 with a reinforcing material is not shown in detail, but is wound around the transport drum D (see FIG. 7) so that the side where the rib 112 is erected is positioned on the outer peripheral surface side, Stored in a factory or transported to a construction site.

  Such a band-like member 100 with a reinforcing material is supplied to the pipe making apparatus 1 described later and is spirally wound so that the back surface side of the substrate 111, that is, the side where the rib 112 is erected is the outer peripheral surface side. The At this time, as shown in FIGS. 1A and 1B, one side edge portion (stepped portion 113) of the subsequent band member 100 with reinforcing material among the band members 100 and 100 with reinforcing material adjacent to each other. The molten resin c is applied to the other side edge of the subsequent band member 100 with the reinforcing material coated with the molten resin c outside the other side edge part of the preceding band member 100 with the reinforcing material (the preceding reinforcing material). The one side edge of the substrate 111 of the subsequent band member 100 with the reinforcing material is arranged on the other side edge of the substrate 111 of the preceding band member 100 with the reinforcing material. Then, the rehabilitation pipe S (see FIG. 2) having a predetermined pipe diameter is produced.

  Next, the pipe making apparatus 1 will be described with reference to FIGS.

  The pipe making apparatus 1 includes a guide frame 2 that spirally winds a belt-like member 100 with a reinforcing material (hereinafter referred to as a belt-like member 100 except for the case of accuracy) and a circumferential interval between the guide frame 2 and the guide frame 2. A plurality of guide rollers 3 provided rotatably, and provided on the guide frame 2, spirally wound and supplied to the other side edge of the preceding strip-like member 100 and continuously to the pipe making apparatus 1. And the drive mechanism 4 that sandwiches and feeds the adjacent belt-shaped members 100, 100 between them and the guide frame 2 that is positioned in front of the drive mechanism 4. Of the adjacent strip-shaped members 100, 100 that are provided to the side and soften one side edge (stepped portion 113) of the subsequent strip-shaped member 100 supplied to the pipe making apparatus 1, and the molten resin c And a extrusion welding machine 5 for fabric.

  The guide frame 2 is formed by integrally connecting a pair of front and rear annular frames 21 and 21 with a plurality of connecting members 22 at intervals in the circumferential direction. The guide frame 2 is divided into a plurality of pieces (in the embodiment, three pieces at 120 degrees), and the guide frame 2 is carried into the manhole in a divided state and is assembled in an annular shape in the manhole. .

  The front annular frame 21 corresponds to the bent portion 211 in addition to a part of the arc bent in an L shape inward corresponding to the drive mechanism 4 and the extrusion welding machine 5 described later. In this portion, an arcuate auxiliary frame 23 is located between the front and rear annular frames 21 and 21 and is connected to the rear annular frame 21 via a connecting member 22.

  The guide roller 3 is rotatably supported via a bearing (not shown) around each connecting shaft 31 fixed between the front and rear annular frames 21 and 21 constituting the guide frame 2.

  However, the portion of the guide roller 3 corresponding to the bent portion 211 of the front annular frame 21 is rotatably supported between the auxiliary frame 23 and the rear annular frame 21, and between the front and rear annular frames 21, 21. The guide roller 3 is provided with a substantially half length.

  Here, the guide roller 3 is made of metal or synthetic resin, and a plurality of grooves 3 a (see FIG. 3) having a width and depth that can accommodate the ribs 112 of the belt-like member 100 with a margin are provided on the belt-like member 100. It is formed corresponding to each rib 112. Thereby, the outer peripheral surface of the guide roller 3 comes into contact with the back surface of the substrate 111 in the belt-like member 100 that forms the rehabilitation pipe S. Further, when the belt-like member 100 whose back surface is restricted by the guide roller 3 and wound spirally is rotated 360 degrees once, the preceding belt-like member 100 has a width of the belt-like member 100 with respect to the subsequent belt-like member 100. It is set so as to be displaced forward by a corresponding length. That is, in the guide roller 3, the mounting position of the guide roller 3 in the tube axis direction with respect to the connecting shaft 31 is adjusted so that the groove 3a gradually shifts in the tube axis direction as the guide roller 3 moves in the circumferential direction. Although not shown in detail, the roller portion of the guide roller 3 corresponding to one side edge (stepped portion 113) of the belt-like member 100 is formed to have a slightly smaller diameter than the other roller portions.

  The drive mechanism 4 includes a mounting frame 41 fixed to the guide frame 2 using a space between the bent portion 211 of the annular frame 21 in front of the guide frame 2 and the auxiliary frame 23, and an outer roller provided on the mounting frame 41. The pinch roller 42 includes a pair 421 and an inner roller 422, and a hydraulic motor (not shown) that is fixed to the mounting frame 41 and rotates the pinch roller 42 via the speed reduction mechanism 43.

  Here, the speed reduction mechanism 43 shows only the sprocket 431 provided on the output shaft of the hydraulic motor provided on the mounting frame 41 and the rotation shaft of the outer roller 421 (only the sprocket provided on the rotation shaft of the outer roller 421 is shown in FIG. )), And a chain 432 wound between the sprockets 431 and gears 433 and 433 provided on the rotation shaft of the outer roller 421 and the rotation shaft of the inner roller 432, respectively, and meshing with each other, and the hydraulic motor is driven to rotate. As a result, the outer roller 421 is rotated via the sprocket 431 and the chain 432, and the inner roller 422 is rotated in a direction opposite to the rotation direction of the outer roller 421 via gears 433 and 433 that are meshed with each other.

  Further, the outer surface roller 421 rotates in contact with the back surface of the substrate 111, that is, the surface serving as the outer peripheral surface of the renovated pipe S, between the adjacent ribs 112, 112 of the belt-shaped member 100. At this time, the outer peripheral surface of the outer roller 421 is knurled so that the belt-like member 100 can be fed out without slipping.

  In addition, the roller of the position corresponding to the one side edge part (stepped part 113) of the outer surface roller 421 is formed in a slightly smaller diameter than the other rollers, and is not subjected to knurling.

  On the other hand, the inner surface roller 422 is formed in a cylindrical shape from a relatively hard material such as iron or plastic, and the outer peripheral surface thereof is a flat surface of the substrate 111 in the strip member 100, that is, the inner peripheral surface of the rehabilitating pipe S. Rotates in contact with the surface on the side.

  The extrusion welding machine 5 is configured by consolidating a hot air machine unit, a plasticizing unit, and a welding rod supply unit in a body 51, takes in outside air and heats it, and blows out hot air through the blowout nozzle 52, and uses polyethylene, polypropylene, or the like. A welding rod 61 (see FIG. 2) made of linear plastic is guided and heated and melted, and the molten resin c is extruded from the extrusion nozzle 53. The extrusion welding machine 5 is substantially in contact with one side edge (step 113) of the belt-like member 100 immediately before the blowout nozzle 52 and the extrusion nozzle 53 are supplied to the pinch roller 42 of the drive mechanism 4 in the pipe making apparatus 1. The guide frame 2 is fixed to the guide frame 2 using a space between the bent portion 211 of the front annular frame 21 and the auxiliary frame 23 so as to face each other in the state.

  The welding rod 61 is formed by linearly forming the same material as the resin material forming the synthetic resin belt-shaped member 110 of the belt-shaped member 100, and is formed on the welding rod reel 6 by being wound in a reel shape. The guide frame 2 is provided in the vicinity of the extrusion welder 5 (see FIG. 2).

  Here, when joining the adjacent belt-like members 100, 100 with the molten resin c, the preceding belt-like member in which the one side edge of the subsequent belt-like member 100 is overlapped with the one side edge of the following belt-like member 100. The other side edge portion of 100 is also preferably softened to a substantially molten state. In this case, a new heated air blowing nozzle may be disposed to face the other side edge of the preceding belt-like member 100.

  As shown in FIGS. 5 and 6, the curl correction device 10 includes a guide lane 11 in which a straight through passage 11 a corresponding to the cross-sectional shape of the belt-like member 100 is formed, and an inlet side end and an outlet of the guide lane 11. The guide lane 11 is composed of feed rollers 12 and 12 that are rotatably supported by cutting out a part of the guide lane 11 at the side ends, and a motor 13 that rotationally drives the feed roller 12 on the inlet side. Support shafts 14 are provided projecting outward on both side surfaces of a substantially intermediate portion in the longitudinal direction. The curl correction device 10 is rotatably supported via a support shaft 14 by a pair of guide rails 16 installed over a support column 15 erected with the manhole M interposed therebetween.

  Here, the feed roller 12 is configured by providing a disk-shaped roller 121 having a width disposed between adjacent ribs 112, 112 of the belt-shaped member 100 so as to be concentric with the rotation shaft 122, and an outer peripheral surface of the disk-shaped roller 121. However, the diameter and the rotation axis are set so that the gap corresponding to the thickness of the substrate 111 of the strip member 100 is located between the bottom surface of the guide lane 11 and the through passage 11a. Therefore, by rotating the feed roller 12 via the motor 13, the substrate 111 of the belt-like member 100 is sandwiched between the outer peripheral surface of the disc-like roller 121 and the bottom surface of the through-passage 11 a of the guide lane 11, and toward the exit side. Can be sent out forcibly.

  Note that the feed roller 12 on the inlet side is knurled on the outer peripheral surface of the disk-shaped roller 121 and feeds the belt-like member 100 without slipping.

  On the other hand, the guide rail 16 is provided with a support member 161 having a support portion of the support shaft 14 so as to be movable along the longitudinal direction thereof. The support member 161 is used with respect to the guide rail 16 using a bolt or the like. By fixing so as not to move, the support shaft 14 arranged on the support portion of the support member 161, that is, the curl correction device 10 can be positioned.

  In addition, a traction tool 17 such as a chain block is disposed between the curl correction device 10 and the support column 15. By adjusting the distance from the support column 15 via the traction tool 17, The inclination angle of the curl correction device 10 with respect to the ground can be arbitrarily changed so that the belt-like member 100 can be smoothly introduced.

  Next, a pipe manufacturing method of the renovated pipe S for rehabilitating the existing pipe K using the pipe manufacturing apparatus 1 configured as described above will be described.

  First, the existing pipe K is provided with a manhole for every predetermined span. In the adjacent manhole, one manhole M1 is set as the start manhole of the construction target section (rehabilitation section), and the other manhole M2 is set as the reaching manhole. A case where the rehabilitated pipe S is formed in the existing pipe K from the starting manhole M1 to the reaching manhole M2 will be described.

  As preparation before construction, the remanufactured pipe S is made of a transport drum D (with a turntable) wound with a belt-like member 100, a pipe making apparatus 1, a curl correction apparatus 10, and a power unit (not shown). Prepare the transport drum D and the power unit on the ground on the starting manhole M1 side.

  The pipe making apparatus 1 is disassembled into a guide frame 2 provided with a guide roller 3, a drive mechanism 4, and an extrusion welder 5, and the guide frame 2 is further divided into a plurality of parts. And each element of the divided pipe manufacturing apparatus 1 is assembled after it is carried in through the manhole M1. The assembled pipe making apparatus 1 is supported in a suspended state using a truck crane or the like in the starting manhole M1 (see FIG. 2).

  Further, the curl correction device 10 stands on the starting manhole M1 side ground with a support column 15 sandwiched between the manholes M1, and after a pair of guide rails 16 is installed over the support column 15, the crane uses a crane or the like. The straightening device 10 is lifted, and the support shaft 14 is positioned on the support portion of the support member 161 and disposed on the pair of guide rails 16. Next, in consideration of the positional relationship between the curl correcting device 10 with the transport drum D and the pipe making device 1, the belt-like member 100 fed out from the transport drum D is introduced into the starting manhole M 1 through the curl correcting device 10. While being moved along the guide rail 16 so that it can be smoothly supplied to the pipe making apparatus 1, the inclination angle is adjusted via the traction tool 17.

  When such a preparatory work is completed, the belt-like member 100 is pulled out from the transport drum D arranged on the ground, pushed in from the entrance of the through-passage 11a of the guide lane 11 in the curl correction device 10, and pulled out from the exit. That is, by driving the motor 13 of the curl correction device 10, the feed roller 12 on the inlet side is driven to rotate, and the substrate 111 of the belt-like member 100 inserted into the through passage 11a of the guide lane 11 is attached to the bottom surface of the through passage 11a. And forcibly send it out. As a result, the belt-shaped member 100 passes through the through-passage 11a of the guide lane 11, is sandwiched between the feed rollers 12 on the outlet side, and is pulled out from the outlet side. In this case, the band-shaped member 100 is formed with a curl having a radius of curvature along the curvature radius of the upstream-side band-shaped member 100 when the belt-shaped member 100 is wound around the transport drum D. By passing through the straight through passage 11a of the guide lane 11 having the length, the belt-like member 100 is continuously plastically deformed into a substantially straight shape, and the curl is corrected.

  That is, the belt-like member 100 fed out from the transport drum D is plastically deformed substantially linearly by the curl correction device 10 and the curl is corrected and introduced into the manhole M.

  Next, the belt-like member 100 continuously fed out from the curl correcting device 10 is supplied to the pinch roller 42 via the starting manhole M1 and the mounting frame 41 of the driving mechanism 4 in the pipe making apparatus 1 supported in the starting manhole M1. At the same time, it is pulled out from the pinch roller 42 and sent to the inner peripheral side of the guide roller 3 provided on the guide frame 2. The belt-like member 100 pulled out from the pinch roller 42 and sent out to the inner peripheral side of the guide roller 3 is spirally wound with its rib 112 guided by the groove 3a of the guide roller 3. When the belt-like member 100 is spirally wound 360 degrees along the guide roller 3 of the guide frame 2 and reaches the pinch roller 42 of the drive mechanism 4 again, the belt-like member 100 is moved in the pipe making direction by the width. It shifts and is located in front of the pinch roller 42, and one side edge of the subsequent strip member 100 that is continuously supplied overlaps with the other side edge.

  Here, when the extrusion welding machine 5 is operated, the outside air is sucked and heated, and the heated air is blown out from the blowing nozzle 52 toward one side edge of the succeeding belt-like member 100 to be softened to a substantially molten state. At the same time, the welding rod 61 is drawn into the welding rod reel 6 to be melted by heating, and the molten resin c is pushed out from the extrusion nozzle 53 and applied to one side edge (stepped portion 113) of the subsequent strip member 100. In this case, the extrusion welding machine 5 is mounted on the inner side of the guide frame 2, and the extrusion nozzle 53 is opposed to one side edge of the subsequent belt-like member 100 in a substantially contact state, whereby the molten resin c Can be reliably applied to one side edge of the belt-like member 100.

  In this state, the hydraulic motor of the drive mechanism 4 in the pipe making apparatus 1 is rotationally driven in synchronization with the drive of the motor 13 of the curl correction apparatus 10. As a result, the outer roller 421 is rotated via the sprocket 431 and the chain 432, and the inner roller 422 is rotated in the direction opposite to the rotation direction of the outer roller 421 via the meshing gears 433 and 433, thereby leading the belt-shaped member. 100 and the subsequent belt-shaped member 100 are sandwiched, and one side edge (stepped portion 113) of the subsequent belt-shaped member 100 is overlapped with the other side edge of the preceding belt-shaped member 100 and sent out in the circumferential direction. At this time, one side edge portion of the subsequent belt-like member 100 is softened in a substantially molten state, and the molten resin c is applied to the one side edge portion, so that it is adjacent to the pinch roller 42. The band-shaped members 100 and 100 are fed out in the circumferential direction with one side edge of the subsequent band-shaped member 100 integrally joined to the other side edge of the preceding band-shaped member 100. That is, when the adjacent belt-like members 100 and 100 wound spirally along the guide roller 3 are sent out from the pinch roller 42, their other side edges and one side edge are wound spirally. In this state, they are joined together to form a pipe, and are sent out forward while rotating as the rehabilitation pipe S.

  Here, the supply speed of the belt-like member 100 by the drive mechanism 4 of the pipe making device 1 and the supply speed of the belt-like member 100 sent out from the curl correction device 10 are the same, and no excess or deficiency occurs.

  Hereinafter, the curl is corrected by the curl correction device 10 and the belt-like member 100 is smoothly supplied to the pipe making device 1 through the manhole M. On the other hand, when the belt-like member 100 is supplied to the pipe-making device 1, one side edge of the belt-like member 100 is heated and softened in the pipe-making device 1, and a molten resin c is applied to the one side edge. By being continuously supplied to the pinch roller 42 of the driving mechanism 4, one side edge of the subsequent belt-like member 100 is integrally joined to the other side edge of the preceding belt-like member 100 in the pinch roller 42. Then, the regenerated pipe S is continuously produced. Then, the renovated pipe S that has been piped is removed from the pipe making apparatus 1 by being pushed out while being rotated, and is inserted into the existing pipe K toward the reaching manhole M2 (see FIG. 7).

  In this way, the rehabilitated pipe S is produced from the belt-like member 100 continuously supplied to the pipe making apparatus 1, and the regenerated pipe S that has been produced is inserted into the existing pipe K while being rotated. If the end of the pipe reaches the reaching manhole M2 and the production of the renovated pipe S is completed over the entire length of the construction target section of the existing pipe K, the strip-shaped member 100 at the end of the regenerated pipe S is cut, and then curl correction is performed. While removing the apparatus 10, the pipe making apparatus 1 is disassembled and removed from the starting manhole M1. That is, the drive mechanism 4 and the extrusion welder 5 are removed from the guide frame 2, and the guide frame 2 is divided into a plurality of parts and pulled up from the starting manhole M1.

  By the way, in the above-described embodiment, a pair of guide rails 16 are installed on the ground of the starting manhole M1 via the support column 15 placed with the manhole M1 interposed therebetween, and the curl correction device 10 is supported on the guide rail 16. As shown in FIG. 9, as shown in FIG. 9, the guide rail 16 is installed over the peripheral wall in the manhole M <b> 1 using a jack 18 or the like, and the curl correction device 10 is attached to the guide rail 16 installed in the manhole M <b> 1. May be supported.

  In the above-described embodiment, the case where the inlet-side feed roller 12 is rotationally driven via the motor 13 is exemplified. However, the outlet-side feed roller 12 may be rotationally driven via the motor. In that case, the feed roller 12 on the outlet side may be knurled. Alternatively, the inlet-side feed roller 12 and the outlet-side feed roller 12 may be rotationally driven via motors that rotate in synchronization.

  Furthermore, in the above-described embodiment, the band member 100 with the reinforcing material in which the metal reinforcing material 120 is embedded in the rib 112 of the synthetic resin band member 110 is illustrated, but as shown in FIGS. 10 (a) and 10 (b). Further, a band member 100 with a reinforcing material, in which a metal reinforcing material 130 bent into a substantially W-shaped cross section over the ribs 112, 112 having a T-shaped cross section is attached to the back side of the band member 110 made of synthetic resin. Also good.

  The synthetic resin belt-like member 110 of the reinforcing member-like belt member 100 has a bonding convex portion 114 standing on the back side of one side edge portion of the substrate 111, and the other side edge portion of the substrate 111 is connected to the bonding convex portion. 114 is formed in a stepped portion 113 stepped down to the back side by the thickness of the substrate 111, and the joint convex portion 114 is fitted to the stepped portion 113 so that the side edge portion of the substrate 111 provided with 114 can be disposed. Possible joint recesses 115 are formed. In addition, inclined ribs 116 are formed in the bonding recess 115 so as to be positioned on the protruding side of the bonding recess 115 as the distance from the substrate 111 increases.

  Such a band-like member 100 with a reinforcing material is supplied to a pipe making apparatus (not shown) so that the back side of the substrate 111, that is, the side where the reinforcing ribs 112 and the like are erected is the outer peripheral side, and its joining mechanism 1, of the band-like members 100, 100 with reinforcing material adjacent to each other, the bonding concave portion 115 of the other band-like member 100 with reinforcing material is placed outside (the preceding reinforcing material). It fits and joins from the outer peripheral side of the band-like member 100. Thereby, the strip | belt-shaped members 100 and 100 with a reinforcing material which adjoin each other are mutually joined, and the helical tube of a predetermined | prescribed pipe diameter can be manufactured.

  At this time, the stepped portion 113 of the succeeding band member 100 with the reinforcing material is disposed on one side edge portion of the substrate 111 on which the joining convex portion 114 of the preceding belt member 100 with the reinforcing material is provided. The inclined rib 116 of the subsequent band member 100 with reinforcing material is locked to the reinforcing rib 112 on the side where the joint convex portion 114 of the band member 100 with reinforcing material is provided.

  Furthermore, in the above-described embodiment, the case where the motor 13 that rotationally drives the feed roller 12 is provided in the guide lane 11 has been described, but it is not necessarily required to be provided in the guide lane 11. For example, although not shown in detail, a feed mechanism comprising a pair of rollers that sandwich the band-like member 100 with a reinforcing material between the attachment frame 41 of the pipe making apparatus 1 and a motor that rotationally drives one of the pair of rollers. May be provided. In this modified example, when the belt-shaped member 100 with the reinforcing material is sandwiched between the pair of rollers through the through-passage 11a of the guide lane 11, and the motor is driven to rotate, one of the rollers is rotated. The belt-like member 100 with a reinforcing material is sandwiched between the front and rear feed rollers 12 and the bottom surface of the through-passage 11a of the guide lane 11 from the through-passage 11a. It is forcibly pulled out and the curl is corrected.
