Description

  The present invention relates to a pipe making apparatus for rehabilitating pipes for rehabilitating existing pipes such as aging sewer pipes, water pipes, agricultural water pipes, and gas pipes.

  Conventionally, in order to rehabilitate an existing pipe that has deteriorated, a band-shaped member with joints formed on both side edges is drawn into the existing pipe, and spirally wound to join the adjacent band-shaped members together. It is practiced that a rehabilitating pipe is produced and a belt-shaped member is newly supplied to the rehabilitated pipe produced without rotating to additionally form the rehabilitating pipe in the axial direction of the existing pipe. For example, as described in Patent Document 1, a transport drum in which a belt-shaped member is wound into a hollow cylindrical shape is installed on the ground, and a pipe-making device is arranged in an existing pipe, and is drawn out in a spiral shape from the transport drum. The strip member was introduced into the pipe making device in the existing pipe, and the pipe making device was rotated around the axis of the existing pipe to join the joining portions of the adjacent strip members to make the rehabilitated pipe, and the pipe was made. A new strip-shaped member is supplied to the rehabilitation pipe, and the rehabilitation pipe is additionally formed in the axial direction of the existing pipe.

  As shown in FIG. 14, the pipe making apparatus 1 includes a molding frame 2 formed in a substantially annular shape by connecting a plurality of link bodies 21 in which a pair of link members are rotatably connected via a connecting shaft in order. The molding frame 2 includes a plurality of guide rollers 3 rotatably supported on the connecting shafts of the link bodies 21, an inner surface roller (not shown), and an outer surface roller 43 provided on the molding frame 2. It is comprised from the joining mechanism 4 which joins the junction parts of the strip | belt-shaped member 100 adjacent. The joining mechanism 4 forms the rehabilitation pipe S by rotating the inner surface roller and the outer surface roller 43 with the belt-like member 100 sandwiched by the drive of the hydraulic motor 45, and moves around the rehabilitation pipe S by the reaction. That is, the pipe making apparatus 1 revolves around the axis of the existing pipe K.

  The strip-shaped member 100 used is formed by extruding a flexible synthetic resin, for example, hard vinyl chloride. As is well known, a plurality of strip-shaped members 100 are formed on the back surface of the strip-shaped substrate 101. Reinforcing ribs 102 having a T-shaped cross section (two in the embodiment) are provided with their tips parallel to the substrate 101 (see FIG. 15). Then, the bonding convex portion 103 is erected on the back surface of one side edge portion of the substrate 101, and the side edge portion of the substrate 101 provided with the bonding convex portion 103 is disposed on the other side edge portion. A stepped portion 104 is formed in a stepped portion 104 that is stepped down to the back side by the thickness of the substrate 101, and a joint concave portion 105 into which the joint convex portion 103 can be fitted is provided. In addition, an inclined rib 106 that is inclined so as to be positioned on the protruding side of the bonding recess 105 as it moves away from the substrate 101 is formed in the bonding recess 105, and the tip of the inclined rib 106 forms the other side edge of the band-shaped member 100. Forming.

  Such a belt-like member 100 is drawn out from the center side of a transport drum wound in a hollow cylindrical shape and transported to the site, and the back side of the substrate 101, that is, the side where the reinforcing ribs 102 and the like are erected is the outer periphery. As shown in FIGS. 15 (a) and 15 (b), two strip members 100, 100 adjacent to each other are supplied to the pipe making apparatus 1 arranged in the existing pipe K so as to be on the side. Of these, by fitting the joint convex portion 103 of one belt-like member 100 into the joint concave portion 105 of the other belt-like member 100 from the inside (the inner peripheral side of the preceding belt-like member 100), the adjacent belt-like members 100, 100 are The rehabilitation pipe S (see FIG. 14) having a predetermined pipe diameter can be produced by joining together.

  At this time, the side edge portion of the substrate 101 provided with the joining convex portion 103 of the subsequent strip-shaped member 100 is arranged in the stepped portion 104 of the preceding strip-shaped member 100 and the joining convex portion 103 of the subsequent strip-shaped member 100 is arranged. The inclined rib 106 of the belt-like member 100 preceding the provided reinforcing rib 102 is locked.

  In such a pipe manufacturing apparatus 1, the spiral belt-like member 100 drawn from the transport drum is supplied while being substantially maintained at the diameter and pitch set based on the diameter, shape, etc. of the existing pipe K. For example, when the spiral belt-like member 100 drawn out from the transport drum is consumed by making the rehabilitated pipe S by the pipe-making device 1 and the supply of the belt-like member 100 to the pipe-making device 1 is insufficient, As the diameter of the strip-shaped member 100 gradually decreases, the pitch increases, and finally, the strip-shaped member 100 extends and breaks. On the other hand, when the supply of the strip member 100 to the pipe making apparatus 1 becomes excessive, the diameter of the spiral strip member 100 gradually increases. Finally, the strip member 100 is turned over and the strip member 100 is returned to its original state. It takes a lot of time to recover. For this reason, workers are respectively arranged on the ground facing the manhole and the bottom of the manhole, and the flow of the spiral belt-shaped member 100 drawn from the transport drum and the spiral belt-shaped member 100 heading from the bottom of the manhole toward the axial direction of the existing pipe K. The belt member 100 is supplied to the manhole while adjusting the diameter and pitch of the spiral belt member 100 to be substantially constant, and the belt member is supplied to the pipe making apparatus 1. Yes. Further, when the rehabilitated pipe S is manufactured, an operator is placed in the regenerated regenerated pipe S with a set span, the flow of the spiral band member 100 supplied from the manhole is observed, and the spiral is The strip member 100 is supplied toward the pipe making apparatus 1 while adjusting the diameter and pitch of the strip member 100 so as to be maintained substantially constant.

  As described above, when the spiral belt-like member 100 is supplied to the pipe making apparatus 1 while maintaining the diameter and pitch substantially constant, the belt-like member 100 is placed in the set path in the molding frame 2 of the pipe making apparatus 1. A guide that regulates and leads to the joining mechanism 4 is provided (see, for example, Patent Document 2).

JP-A-9-32968 Japanese Patent Laid-Open No. 11-141735

  By the way, the guide of the pipe making apparatus described above is configured by rotatably supporting four rollers on each side of the square, and the belt-like member can move relatively freely in the guide. Therefore, it has not been possible to cope with a sudden change of the belt-like member before and after passing through the guide. For example, as described above, the spiral belt-like member is supplied to the pipe making apparatus while maintaining the set diameter and pitch in the rehabilitation pipe, but when passing through a guide provided in the pipe making apparatus, the pipe making apparatus The spiral shape (path) of the belt-like member greatly changes in the three-dimensional direction so as to approach the diameter and pitch of the rehabilitated pipe produced by the above. In other words, the pitch of the spiral belt-shaped member after passing through the guide becomes extremely smaller than that before passing through the guide, and the diameter after passing through the guide becomes larger than before passing. Therefore, before and after the guide, the inflow angle of the strip member with respect to the axial direction of the molding frame, the inflow angle of the strip member with respect to the circumferential direction, and the twist of the strip member (inclination angle around the longitudinal direction of the strip member) are large. Change. On the other hand, since the band-shaped member can freely move in the guide, the guide cannot regulate the path of the band-shaped member with respect to the bonding mechanism uniformly, and the bonding mechanism can join adjacent band-shaped members. There was a case where the situation became insufficient or could not be joined. For this reason, it has been necessary to adjust the diameter, pitch, and twist of the spiral belt-shaped member by the worker so that the worker is arranged near the pipe making apparatus and the belt-shaped member can be smoothly joined in the joining mechanism.

  As a result, a large number of workers are required for the production of the rehabilitated pipe, which increases the cost.

  The present invention has been made in view of such problems, and regulates the path of the belt-shaped member without requiring adjustment work by an operator, supplies the belt-shaped member to the joining mechanism, and smoothes the rehabilitation pipe. The present invention provides a pipe making apparatus for a rehabilitated pipe that can be made.

  The present invention draws a belt-like member with joints formed on both side edges into an existing pipe, spirally winds them together, joins the joints of adjacent belt-like members together, and manufactures a rehabilitation pipe. In a pipe making apparatus for a rehabilitated pipe in which a belt-shaped member is newly supplied to the rehabilitated pipe and the rehabilitated pipe is additionally formed in the axial direction of the existing pipe, A molding frame having a perimeter corresponding to each other, a plurality of guide rollers rotatably supported by the molding frame, and joints of adjacent belt-like members provided on the molding frame. And a pair of inner guides that are provided on the molding frame and that have a pair of inner guides and outer guides that sandwich the band-like member and prevent movement in the width direction. And outside guide , Supported rotatably around an axis parallel to the axis of the molding frame, fixed at a set rotational position, and supported so as to be movable in the axial direction of the molding frame. The spiral belt-like member is fixed to the moved position, and the path to the molding frame is regulated via the guide member and supplied to the joining mechanism.

  According to the present invention, a belt-like member having joints formed on both side edges is drawn in, spirally wound to join the joints of adjacent belt-like members to each other, and a rehabilitated pipe is produced. A strip-shaped member is newly supplied to the rehabilitated pipe so that the rehabilitated pipe is additionally formed in the axial direction of the existing pipe. That is, the belt moves around the axis of the existing pipe by the reaction force caused by sandwiching and rotating the band-shaped member, and the joint portions of the adjacent band-shaped members are bonded to each other to produce a regenerated pipe.

  Here, a guide member is provided in the forming frame of the pipe making apparatus, and the path of the belt-like member supplied to the joining mechanism is regulated to be constant. In other words, the inner guide and the outer guide that form a pair of guide members are fixed by adjusting the movement position in the axial direction of the molding frame, and are also rotated around the axis parallel to the axis of the molding frame. The belt-shaped member pulled out through the guide member is sandwiched between the pair of inner guide and outer guide at the fixed position of the guide member, and is prevented from moving in the width direction. The path to the molding frame is regulated.

  As a result, the belt-like member can be regulated to the set path and supplied to the joining mechanism, and the rehabilitated pipe can be smoothly produced. Therefore, the adjustment work of the belt-shaped member by the operator becomes unnecessary, and the cost can be reduced.

  In the present invention, it is preferable that one guide member is provided on the molding frame, or a plurality of guide members are provided at intervals in the circumferential direction. Thereby, an appropriate number of guide members can be provided corresponding to the diameter of the rehabilitation pipe, and the belt-like member can be restricted to the set path.

  In the present invention, it is preferable that the paired inner guide and outer guide are supported so as to be rotatable about a radial axis of the molding frame. As a result, when a load acts on the belt-like member, the belt-like member can be rotated following the load, and the inflow angle of the belt-like member with respect to the axial direction of the molding frame can be changed to prevent the belt-like member from being damaged.

  In the present invention, it is preferable that the paired inner guide and outer guide are rotatably supported around the radial axis of the molding frame and are fixed at a set rotational position. Thereby, the inflow angle of the strip | belt-shaped member with respect to the axial direction of a shaping | molding flame | frame can be adjusted and fixed, and the path | route of a strip | belt-shaped member can be controlled.

  In the present invention, it is preferable that the pair of inner guide and outer guide are an inner roller and an outer roller that are rotatable with a band-shaped member interposed therebetween. Thereby, a strip | belt-shaped member can be sent out stably reducing friction as much as possible.

  In the present invention, an outer guide roller and an inner guide roller that is paired with the outer guide roller and sandwiches the belt-like member are rotatably supported on the forming frame, and the outer guide is supported. It is preferable that the roller is supported so as to be movable in the radial direction and the axial direction with respect to the molding frame, and is fixed to a moving position set in each direction. As a result, the belt-like member supplied to the joining mechanism is sandwiched at the preceding stage to prevent movement in the width direction. Therefore, in the joining mechanism, the path of the succeeding belt-like member with respect to the preceding belt-like member is regulated, and the rehabilitation pipe Can be produced more reliably.

  In the present invention, the guide member is fixed to the link body of the molding frame through a pair of left and right elongated holes, and the guide is fixed to the pair of mounting plates through a pair of upper and lower elongated holes. A frame, a bearing member fixed to the guide frame through a guide hole parallel to the axis of the molding frame, and supported rotatably about the radial axis of the molding frame via the bearing of the bearing member. An outer frame having a plurality of outer guides, and an inner frame having one or more inner guides that are detachably fixed to the outer frames and sandwich the belt-shaped member in pairs with the outer guides. It is preferable that it is comprised from these. As a result, the outer guide and the inner guide that make a pair can be moved in the axial direction of the molding frame to adjust the fixing position, and the axial center parallel to the axial center of the molding frame at the fixing position. The fixed position can be adjusted by rotating it around. Therefore, it is possible to adjust and fix the inflow angle and twist of the strip-shaped member passing through the pair of outer guide and inner guide with respect to the circumferential direction of the molding frame. Moreover, the inflow angle with respect to the axial direction of the molding frame can be adjusted following the load acting on the belt-like member.

  In the present invention, the guide members are fixed to the molding frame through a pair of left and right elongated holes, respectively, and a guide frame is fixed to the pair of mounting plates through a pair of vertical slots in the vertical direction. The shaft member is fixed to the guide frame through a guide hole parallel to the axis of the molding frame, and has a support shaft extending in the radial direction of the molding frame.

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

  FIG. 1 shows an embodiment of a rehabilitating pipe producing apparatus 1 according to the present invention.

  The pipe making apparatus 1 includes a forming frame 2 that guides the belt-like member 100 in a spiral shape, a plurality of guide rollers 3 that are rotatably provided on the forming frame 2, and an adjacent spiral shape that is attached to the forming frame 2. The belt-like members 100 and 100 are joined to each other, and a guide member 5 that restricts the belt-like member 100 to a set path and supplies it to the downstream side.

  As shown in FIG. 2, the molding frame 2 is configured such that an inner link frame 22 that is an inner link member and an outer link frame 23 that is an outer link member are rotatable via a connecting shaft 24. A link body 21 is formed by coupling, and a plurality of link bodies 21 are sequentially coupled to form a substantially ring shape.

  Here, the inner link frame 22 and the outer link frame 23 constituting each link body 21 are a pair of link plates 221 and 231 opposed to each other in the front-rear direction, and one end portions of the pair of link plates 221 and 231 opposed to each other. It is formed in a U-shape from connecting plates 222 and 232 installed between them. Then, the other end portions of the pair of link plates 231 and 231 in the outer link frame 23 are overlapped with the other end portions of the pair of link plates 221 and 221 in the inner link frame 22, respectively. The link body 21 is formed by being rotatably connected to each other.

  Adjacent link bodies 21 and 21 are detachably connected via bolts and nuts by appropriately connecting the connecting plates 222 and 232 of the link frames 22 and 23 and the connecting plates 222 and 232 of the link frames 22 and 23. .

  However, if the pair of specific adjacent link bodies 21 and 21 can be attached and detached so that the forming frame 2 can be formed in a straight line, the remaining connecting plates 222 and 232 are fixed so as not to be attached or detached by welding or the like. It doesn't matter.

  The other end of each of the pair of link plates 221 and 221 of the inner link frame 22 is provided with a rotation restricting piece 26, while the other end of each of the pair of link plates 231 and 231 of the outer link frame 23. The notch 27 corresponding to the rotation restricting piece 26 described above is formed over a certain range on a set radius with the rotation center of the connecting shaft 24 as the center. Thereby, the rotation of the outer link frame 23 relative to the inner link frame 22 is set within a set angle range until the rotation restricting piece 26 of the inner link frame 22 and the cutout portion 27 of the outer link frame 23 abut. The inner link frame 22 and the outer link frame 23 of the link body 21 are prevented from bending more than necessary inward or outward.

  Further, a mounting plate 51 of a guide member 5 described later is bolted to the pair of link plates 221 and 221 facing the inner link frame 22 and the pair of link plates 231 and 231 facing the outer link frame 23. Mounting holes 22a and 23a are formed.

  The guide roller 3 is rotatably provided on the connecting shaft 24 of each link body 21. Here, the guide roller 3 is made of synthetic resin or metal, and is rotatably supported around the connecting shaft 24 via the bearing 25, and comes into contact with the flat surface of the belt-shaped member 100, that is, the inner peripheral surface of the renovated pipe S. Then rotate.

  Further, the guide roller 3 is in the existing pipe K, and is piped while moving around in contact with the inner peripheral surface of the rehabilitated pipe S piped from the adjacent strip members 100 and 100 joined together by the joining mechanism 4. In order to move the device 1 in the axial direction of the existing pipe K, the rotation axis is arranged so as to be orthogonal to the longitudinal direction of the strip-like member 100 constituting the rehabilitation pipe S. In order to arrange the guide roller 3 so as to be orthogonal to the belt-like member 100 constituting the rehabilitation pipe S, for example, at the connecting portion between the pair of link bodies 21 and 21 adjacent to the joining mechanism 4 of the molding frame 2. The one link body 21 may be moved in the tube axis direction with respect to the other link body 21 and fixed to the joining mechanism 4 in the moved state.

  Of the link bodies 21, the link body 21 to which the joining mechanism 4 is attached is provided with an inner surface roller 42 to be described later instead of the guide roller 3, and the joining mechanism with respect to the rotation direction of the pipe making apparatus 1. 4, in the direction opposite to the direction in which the rehabilitating pipe S is formed, the width of the band member 100 is less than the link body 21 to which the joining mechanism 4 is attached so that the link body 21 does not interfere with the supply of the band member 100. It is displaced (see FIG. 3).

  As shown in FIG. 4, the joining mechanism 4 includes a pinch roller 41 in which an inner roller 42 and an outer roller 43 are combined, and a gear box 44 fixed to the outer link frame 23 of the link body 21 in the molding frame 2. And a hydraulic motor 45 that rotates the pinch roller 41 via gears 441, 442, and 443, and the rotation axis of the inner surface roller 42 and the rotation shaft of the outer surface roller 43 are axially oriented with respect to the lead angle of the rehabilitation pipe S. They are arranged so as to be orthogonal to each other and are rotatably supported by the gear box 44 together with the output shaft of the hydraulic motor 45. Then, by rotating and driving the hydraulic motor 45, the inner roller 42 and the outer surface via the gears 441, 442, and 443 that are fixed to the output shaft, the rotation shaft of the inner roller 42, and the rotation shaft of the outer roller 43 and mesh with each other. The rotation direction is set so that the rollers 43 are rotated in opposite directions, and the belt-like member 100 is sandwiched between the inner surface roller 42 and the outer surface roller 43 and sent out.

  Here, the inner surface roller 42 has a length that is approximately twice the width of the belt-like member 100 and is formed into a cylindrical shape by steel or the like, and the preceding spiral belt-like member 100 and the following spiral-like member are formed. The outer diameter is set so that the outer peripheral surface contacts and rotates with the smooth inner peripheral surface of the rehabilitating pipe S formed by the band-shaped members 100 and 100 which are joined to the band-shaped member 100 and adjacent to each other.

  Further, the outer surface roller 43 has a leading end of each reinforcing rib 102 of the band-shaped member 100 in the band-shaped members 100 and 100 adjacent to each other by joining the preceding spiral band-shaped member 100 and the subsequent spiral band-shaped member 100 to each other. And a plurality of small-diameter rollers 431 for supporting the belt-shaped member 100, and a width capable of being inserted between the reinforcing ribs 102, 102 adjacent to the belt-shaped member 100 so as to be disposed between the reinforcing ribs 102, 102 of each belt-shaped member 100. A plurality of large diameter rollers 432 are provided, and the outer peripheral surface of the small diameter roller 431 is knurled. As a result, the small-diameter roller 431 of the outer surface roller 43 rotates without sliding with respect to the reinforcing ribs 102 of the adjacent belt-like members 100 and 100 joined. That is, the outer surface roller 43 rotates in contact with the back surface of the belt-shaped member 100 on the side that becomes the outer peripheral surface of the rehabilitating pipe S by the adjacent belt-shaped members 100 and 100 joined to each other.

  Further, the hydraulic motor 45 is driven by the pressure oil supplied from the hydraulic unit P through the pressure oil hose, and the hydraulic unit P is driven by the electric power supplied from the generator G (see FIG. 9). In this case, the pressure oil hose extending from the hydraulic unit P is connected to the hydraulic motor 45 via the rotary joint, and can supply the pressure oil without affecting the circular movement (revolution) of the pipe making apparatus 1.

  As shown in FIGS. 5 to 7, the guide member 5 is bolted to the link plate 231 of the outer link frame 23 of the adjacent link body 21 in the molding frame 2 (or the link plate 221 of the inner link frame 22). A pair of front and rear mounting plates 51, a bolt fixed over the pair of front and rear mounting plates 51, and a guide frame 52 formed with guide grooves 52a in the axial direction of the molding frame 2, and moved along the guide grooves 52a of the guide frame 52 A bearing member 53 having a support shaft 531 and a bearing 532 rotatably supported by the support shaft 531 and a bearing member 532 rotatably supported by the bearing 532 of the bearing member 53 and spaced in the left-right direction. An outer frame 54 having two outer rollers 541 that are rotatably supported as outer guides, and an outer frame An inner frame having two inner rollers 551 as inner guides, which are detachably bolted to the drum 54, and are rotatably supported at intervals in the left-right direction in pairs with the outer rollers 541. 55. The inner roller 551 is formed in a cylindrical shape corresponding to the surface of the belt-like member 100, while the outer roller 541 corresponds to the back surface of the belt-like member 100 and the tip of the reinforcing rib 102 of the belt-like member 100. The small-diameter roller 5411 and the small-diameter roller 5411 to be supported are integrally formed, and a plurality of large-diameter rollers 5412 having a width that can be inserted between adjacent reinforcing ribs 102 and 102 of the belt-like member 100 are formed. As a result, the belt-like member 100 sandwiched between the inner roller 551 and the outer roller 541 is prevented from moving in the width direction.

  Here, in order to adjust the fixing position of the molding frame 2 with respect to the link body 21, a pair of elongated holes 51 a extending in the left-right direction are formed in the mounting plate 51, and the axis of the molding frame 2 of the guide frame 52 is formed. A pair of elongated holes 51b extending in the vertical direction is formed to adjust the rotation position (inclination angle) around the axis parallel to the axis. Thereby, as will be described later, the inclination angle of the guide frame 52 around the axis parallel to the axis of the molding frame 2, that is, the outer roller of the outer frame 54 supported rotatably with respect to the guide frame 52. It is possible to adjust the inflow angle and twist of the belt-shaped member 100 that is drawn between the inner roller 551 of the inner frame 541 and the inner frame 55 with respect to the circumferential direction of the molding frame 2.

  Although the outer roller 541 that is rotatable as the outer guide and the inner roller 551 that is rotatable as the inner guide are illustrated, the belt-shaped member 100 may be sandwiched to prevent movement in the width direction. The shape of the roller is not limited, and it is not always necessary to rotate the roller. In this case, the outer roller 541 and the inner roller 551 are formed of resin, but are not limited to resin, and may be formed of metal, rubber, or a composite material of metal and resin (rubber).

  Next, a construction procedure for rehabilitating the existing pipe K using the pipe making apparatus 1 configured as described above will be described.

  First, the existing pipe K is provided with manholes M and M for each predetermined span. In this example, the manhole on the upstream side of the construction target area (rehabilitation area) is set to the start side manhole M1, and the manhole on the downstream side is set to the arrival side. The manhole M2 is used, and the rehabilitated pipe S is manufactured in the existing pipe K using these manholes M1 and M2. The rehabilitation pipe S is produced from the start side manhole M1 of the existing pipe K toward the arrival side manhole M2.

  As preparation before construction, in order to make the rehabilitated pipe S, a drum D (with a turntable), a pipe making apparatus 1, a hydraulic power unit P, and the like wound with a belt-like member 100 are prepared, as shown in FIG. The drum D is installed on the ground on the start side manhole M1, while the hydraulic power unit P is installed on the ground on the arrival side manhole M2. Moreover, the pipe making apparatus 1 is carried in and installed in the upstream edge part in the existing pipe K used as the rehabilitation object through the starting side manhole M1. At that time, the pipe making apparatus 1 is disassembled into the forming frame 2 provided with the guide roller 3, the joining mechanism 4, and the guide member 5, and then assembled. Next, the pressure oil hose from the hydraulic power unit P is connected to the hydraulic motor 45 of the joining mechanism 4 in the pipe making apparatus 1 through the rotary joint J.

  In addition, about the shaping | molding flame | frame 2, the connection part of a pair of adjacent link bodies 21 and 21 is removed, a plurality of link bodies 21 are carried in one row, and a pair of adjacent link bodies 21, 21 connecting portions are connected to form a substantially annular shape.

  Moreover, about the pipe making apparatus 1, while adjusting the circumference (the number of the link bodies 21) of the shaping | molding flame | frame 2 according to the pipe diameter of the renovated pipe S to be pipe-formed, the internal diameter and use of the existing pipe K to regenerate It adjusts so that it may become a spiral pitch corresponding to the width | variety of the strip | belt-shaped member 100 to perform.

  Further, the guide members 5 are respectively fixed at positions 120 degrees apart from the joining mechanism 4 in the clockwise direction and the counterclockwise direction so as to form a substantially equilateral triangle with the joining mechanism 4 as the center. Specifically, after the inner frame 55 is detached from the outer frame 54 of each guide member 5, the outer link of the adjacent link body 21 at a predetermined position through each of the pair of long holes 51 a of the front and rear mounting plates 51. Each frame is temporarily fixed to the frame 23 (inner link frame 22) via bolts. Next, in the joining mechanism 4, the guide frame of each guide member 5 corresponds to the fixed position with respect to the molding frame 2 so that the belt-like member 100 following the spiral belt-like member 100 that precedes forms a smoothly continuous spiral. After the bearing member 53 is moved along the guide groove 52 a of 52 and the mounting position in the axial direction of the molding frame 2 is adjusted, the bearing member 53 is bolted through the guide groove 52 a of the guide frame 52. As a result, the outer frame 54 that is rotatably supported with respect to the guide frame 52 via the bearing member 53 is positioned, and the axial direction of the molding frame 2 in which the belt-like member 100 faces the joining mechanism 4 at the fixed position. The inflow angle with respect to is regulated.

  If the guide frame 52 is positioned and fixed with respect to the axial direction of the molding frame 2, the strip member 100 passes through the axial direction of the molding frame 2 in each guide member 5 as shown in FIG. 8. Further, after rotating the outer frame 54 with respect to the guide frame 2 via the bearing member 53, the temporary fixing is loosened, and the mounting plate 51 of the mounting frame 51 in the circumferential direction of the molding frame 2 is along the long hole 51 a of the mounting plate 51. The mounting position is adjusted and fixed via bolts, and the rotation position (tilt) of the guide frame 52, that is, the twist of the belt-like member 100 is adjusted along the elongated holes 51b of the mounting plate 51, Temporarily fix. Next, after rotating the outer frame 54 by about 90 degrees with respect to the guide frame 52 via the bearing member 53 so that the belt-like member 100 is along the circumferential direction of the molding frame 2, the temporary fixing is loosened and the mounting plate is again mounted. The rotation position (inclination) of the guide frame 52 along the long hole 51b of 51, that is, the inflow angle of the belt-like member 100 with respect to the circumferential direction of the molding frame 2 is adjusted and fixed through bolts.

  In this case, since the twist of the belt-shaped member 100 adjusted in advance is slightly changed, the twist of the belt-shaped member 100 is adjusted in advance in anticipation of this.

  As a result, the belt-like member 100 drawn out through the two pairs of the outer roller 541 and the inner roller 551 of each guide member 5 is molded based on the fixed position of the guide member 5 with respect to the axial direction and the circumferential direction of the molding frame 2. The inflow angle with respect to the axial direction of the frame 2, the inflow angle with respect to the circumferential direction, and the twist are maintained.

  However, the paired outer roller 541 and inner roller 551 are rotatably supported around the radial axis of the forming frame 2 via the bearing 532 of the bearing member 53 with respect to the guide frame 52. Therefore, the inflow angle of the strip member 100 with respect to the axial direction of the molding frame 2 can be rotated following the load acting on the strip member 100.

  The inflow angle of the band-shaped member 100 with respect to the axial direction of the molding frame 2, the inflow angle with respect to the circumferential direction, and the twist are the pitch of the band-shaped member 100, the diameter of the renovated pipe S to be manufactured, the axis of the molding frame 2. It can be obtained in advance from the mounting position of the guide member 5 with respect to the central direction and the circumferential direction, and may be fixed to a position or inclination set based on the result.

  When such a preparatory work is completed, the belt-like member 100 is sequentially pulled out from the inner peripheral side of the drum D placed on the ground and drawn into the existing pipe K through the starting side manhole M1, and the guide member 5 outside the pipe making apparatus 1 is removed. After being arranged on the side roller 541, the inner frame 55 is put on the outer frame 54 and fixed through bolts and wing nuts. Next, the belt-like member 100 pulled out from the guide member 5 on the downstream side is guided to the joining mechanism 4 and sent out to the outside of the guide roller 3 provided on the molding frame 2 through the joining mechanism 4. As a result, the belt-like member 100 is sandwiched between the inner roller 551 of the inner frame 55 and the outer roller 541 of the outer frame 54, and movement in the width direction is restricted. Further, the positional relationship between the guide member 5 positioned on the upstream side in the supply direction of the belt-shaped member 100 and fixed to the molding frame 2 and the guide member 5 positioned on the downstream side and fixed to the molding frame 2, the downstream side The positional relationship between the guide member 5 and the joining mechanism 4 that are fixed to the molding frame 2 is always constant, and the path of the belt-like member 100 that passes through the upstream guide member 5 to the downstream guide member 5, downstream The path of the belt-like member 100 that reaches the joining mechanism 4 through the guide member 5 on the side is regulated to be constant.

  Next, in a state in which the belt-like member 100 fed to the outside of the guide roller 3 is fed between the inner peripheral surface of the existing pipe K, the pipe making apparatus 1 is rotated around the axis of the existing pipe K, and the belt-like member 100 is moved. It winds around the molding frame 2 several times (1 to 3 times) to produce the rehabilitation pipe Sa for start.

  That is, when the forming frame 2 moves around, the joining mechanism 4 inserts the joining convex portion 103 of the succeeding spiral strip member 100 into the joining recess 105 of the preceding spiral strip member 100 from the inner peripheral side. The side edge portion of the substrate 101 provided with the joint convex portion 103 of the subsequent spiral band member 100 is arranged at the stepped portion 104 of the preceding spiral band member 100, and further, the preceding spiral band member 100 The reinforcing ribs 102 on the side where the joining projections 103 of the subsequent spiral belt member 100 are provided are engaged with the inclined ribs 106 of the belt member 100 so that the adjacent spiral belt members 100 and 100 are joined to each other. Then, the start rehabilitation pipe Sa is manufactured.

  At this time, the path of the belt-like member 100 supplied to the joining mechanism 4 is regulated by the guide member 5. That is, since the relative positional relationship between the adjacent guide members 5 and 5 and between the downstream guide member 5 and the joining mechanism 4 is not changed by the rotation of the pipe producing apparatus 1, the upstream guide member 5 is sandwiched between two pairs of inner roller 551 and outer roller 541 to prevent movement in the width direction, and the molding frame is based on the fixed position of the guide member 5 with respect to the molding frame 2. 2 is supplied to the downstream guide member 5 while maintaining the inflow angle with respect to the axial center direction, the inflow angle with respect to the circumferential direction, and the twist. Similarly, the belt-like member 100 supplied from the upstream guide member 5 and passed through the downstream guide member 5 is also sandwiched between the two pairs of the inner roller 551 and the outer roller 541 and is prevented from moving in the width direction. In addition, based on the fixed position of the guide member 5 with respect to the axial direction and the circumferential direction of the molding frame 2, the inflow angle with respect to the axial direction of the molding frame 2, the inflow angle with respect to the circumferential direction, and the twist are maintained. Supplied.

  If the start rehabilitation pipe Sa is manufactured, the pinch roller 41 is rotated by rotating the hydraulic motor 45 of the joining mechanism 4 of the pipe manufacturing apparatus 1, and the inner surface roller 42 and the outer surface roller 43 cause the belt-shaped member 100 to move. It is sandwiched and sent out, and relatively moves (revolves) along the belt-like member 100 in the direction opposite to the sending direction, and the pipe making apparatus 1 revolves around the axis of the existing pipe K.

  The belt-like member 100 fed through the guide member 5 so as to be adjacent to the start rehabilitation pipe Sa by the rotation of the pinch roller 41 has its joint protrusion 103 in the joint concave part 105 of the belt member 100 of the start rehabilitation pipe Sa. In addition to being fitted from the circumferential side, the rear end side edge of the subsequent strip member 100 is disposed at the stepped portion 104 of the strip member 100 of the start rehabilitation pipe Sa. The reinforcing rib 102 on the rear end side of the succeeding strip member 100 is locked to the inclined rib 106 to join the adjacent spiral strip members 100, 100 together, and the rehabilitation tube S is connected to the start rehabilitation tube Sa. The pipe is manufactured (see FIG. 9).

  Thus, the pinch roller 41 of the joining mechanism 4 joins the spiral strip member 100 that follows the leading spiral strip member 100 (the renovated tube S) to produce the renovated tube S while the existing tube K is formed. As a result, the pipe making apparatus 1 eventually produces the strip member 100 in the rehabilitated pipe S, and moves along the inner peripheral face of the existing pipe K (revolution). At the same time, it moves in the axial direction of the existing pipe K toward the reaching side manhole M2.

  That is, the adjacent belt-like members 100, 100 are joined to each other by the pinch roller 41 of the joining mechanism 4 and are piped into the rehabilitated pipe S, and the piped rehabilitated pipe S is arranged in the existing pipe K without rotating. Then, the spiral strip member 100 is newly supplied to the reaching side manhole M2 side of the rehabilitating pipe S, and the rehabilitating pipe S is additionally formed in the axial direction of the existing pipe K toward the reaching side manhole M2.

  At this time, the guide member 5 is fixed to the forming frame 2 of the pipe manufacturing apparatus 1 and follows the revolution around the axis of the existing pipe K of the pipe manufacturing apparatus 1 while maintaining a relative positional relationship with the joining mechanism 4. Move around. Therefore, as described above, the belt-like member 100 is supplied to the joining mechanism 4 while being regulated by the route that is always set via the guide member 5. Thereby, in the joining mechanism 4, the spiral strip member 100 following the preceding spiral strip member 100 can be reliably joined, and the rehabilitated tube can be smoothly produced. In addition, since the guide member 5 executes the supply of the spiral belt-like member 100 that has been adjusted by the operator to the joining mechanism 100, adjustment work by the operator becomes unnecessary, and the cost can be reduced. .

  In each guide member 5, when a load is applied in the width direction of the belt-shaped member 100, the two pairs of the inner roller 551 and the outer roller 541 cause the bearing 532 of the bearing member 53 to move against the guide frame 52 by the load. Therefore, the belt-like member 100 can be slightly rotated around the radial axis of the molding frame 2 to change the inflow angle of the molding frame 2 in the axial direction, thereby preventing the belt-like member 100 from being damaged.

  When the remanufacturing pipe S is formed over the entire length of the construction target area of the existing pipe K, the strip-like member 100 at the end of the rehabilitating pipe S is cut, and then the pipe producing apparatus 1 is disassembled and the pipe producing apparatus 1 And the hydraulic unit P and the like are removed.

  That is, since the forming frame 2 is formed by connecting a plurality of link bodies 21 to each other, the forming frame 2 is connected to the link body by removing the connection of the connecting portions of the pair of adjacent link bodies 21 and 21. 21 and can be pulled out from the reaching manhole M2 in this state.

  10 and 11 show a modified example of the guide member 5.

  The guide member 5A has the same main configuration as the guide member 5 described above. The same reference numerals are assigned to the same safety members, and detailed description thereof is omitted, and different parts will be described.

  In this guide member 5 </ b> A, a shaft member 56 having a support shaft 561 is provided in the guide frame 52 in place of the bearing member 53 of the guide member 5 described above. The outer frame 54 has a shaft support portion (not shown) that rotatably supports the support shaft 561 of the shaft member 56, and the shaft support portion 561 is tightened with a bolt to thereby support the support shaft 561 of the shaft member 56. Can be fixed so as not to rotate.

  The guide member 5A is also fixed at a position about 120 degrees away from the joining mechanism 4 in the clockwise direction and the counterclockwise direction so as to form a substantially equilateral triangle with the joining mechanism 4 as the center.

  The attachment of the guide member 5A is the same, and the attachment of one guide member 5A will be described.

  First, after the inner frame 55 is detached from the outer frame 54 of the guide member 5A, the outer link frame 23 (inner side) of the adjacent link body 21 at a predetermined position through each of the pair of long holes 51a of the front and rear mounting plates 51. Temporary link frame 22) via bolts. Next, in the joining mechanism 4, the guide groove 52 a of the guide frame 52 corresponds to the fixing position with respect to the molding frame 2 so that the spiral member 100 that follows the spiral belt member 100 that precedes forms a smoothly continuous spiral. Then, the shaft member 56 is moved along the axis to adjust the mounting position in the axial direction of the molding frame 2, and then the shaft member 56 is bolted through the guide groove 52 a of the guide frame 52.

  If the shaft member 56 is positioned and fixed with respect to the axial center direction of the molding frame 2, the molding frame 2 so that the strip member 100 passes through the axial direction of the molding frame 2 as shown in FIG. 8. After rotating the outer frame 54 via the shaft member 56, the temporary fixing is loosened, and the mounting position of the mounting plate 51 with respect to the circumferential direction of the molding frame 2 is adjusted along the long hole 51a of the mounting plate 51. In addition to fixing via the bolt, the rotation position (inclination angle) of the guide frame 52, that is, the twist of the belt-like member 100, is adjusted along the elongated hole 51b of the mounting plate 51, and temporarily fixed via the bolt. Next, after rotating the outer frame 54 by about 90 degrees with respect to the guide frame 52 via the shaft member 56 so that the belt-like member 100 is along the circumferential direction of the molding frame 2, the temporary fixing is loosened and the mounting plate is again mounted. The rotation position (inclination angle) of the guide frame 52, that is, the inflow angle of the belt-like member 100 with respect to the circumferential direction of the molding frame 2 is adjusted along the long hole 51b of 51, and is fixed through bolts.

  Further, the outer frame 54 is rotated with respect to the support shaft 561 of the shaft member 56 via the shaft support portion, and the subsequent band-shaped member 100 toward the joining mechanism 4 is rotated so as to form a smoothly continuous spiral. After adjusting the angle, a bolt is screwed into the shaft support portion of the outer frame 54 and fixed so that the shaft support portion (outer frame 54) does not rotate around the support shaft 561.

  As a result, the belt-like member 100 pulled out through the two pairs of the outer roller 541 and the inner roller 551 of the guide member 5A flows in the axial direction of the molding frame 2 based on the fixed position of the guide member 5 with respect to the molding frame 2. The angle, the inflow angle with respect to the circumferential direction, and the twist are maintained.

  Also in this guide member 5A, when the strip member 100 is supplied to the pipe making device 1 and the adjacent strip members 100, 100 are joined to each other by the pinch roller 41 of the joining mechanism 4 to produce the renovated pipe S, the pipe making is performed. While being fixed to the forming frame 2 of the apparatus 1 and maintaining a relative positional relationship with the joining mechanism 4, it moves around the axis of the existing pipe K of the pipe making apparatus 1 following the revolution. Therefore, as described above, the belt-like member 100 is supplied to the joining mechanism 4 while being regulated by the route that is always set via the guide member 5A. That is, the belt-like member 100 is sandwiched between the two pairs of the outer roller 541 and the inner roller 551 and is prevented from moving in the width direction, and the inflow angle with respect to the axial direction of the molding frame 2 and the inflow angle with respect to the circumferential direction. And the twist is regulated and supplied to the joining mechanism 4. Thereby, in the joining mechanism 4, the spiral strip member 100 following the preceding spiral strip member 100 can be reliably joined, and the rehabilitated tube can be smoothly produced. And since the guide member 5 performs supply to the joining mechanism 100 of the spiral strip | belt-shaped member 100 which the operator adjusted until now, the adjustment operation by an operator becomes unnecessary and cost can be reduced.

  By the way, in the pipe manufacturing apparatus 1 described above, together with the guide member 5, an introduction guide roller that is located at the front stage of the joining mechanism 4 and includes a pair of inner guide rollers 61 and outer guide rollers 62 that sandwich the belt-like member 100. 6 can be attached.

  Specifically, as shown in FIGS. 12 and 13, the inner guide roller 61 is rotatably supported by bolts on the outer link frame 23 (inner link frame 22) of the link body 21 in the molding frame 2. After fixing the mounting member 63 to be fixed, a pair of elongated holes 64a are formed in the radial direction of the molding frame 2, and the adjusting member 64 having the shaft support portion 64b of the outer guide roller 62 is bolted to the mounting member 63 through the elongated hole 64a. Further, a support shaft 622 that rotatably supports the outer guide roller 62 via a bearing 621 is movably supported on the shaft support portion 64b of the adjustment member 64, and the movement position is adjusted and fixed. It is.

  Here, the inner guide roller 61 is formed in a cylindrical shape corresponding to the surface of the band-shaped member 100, while the outer guide roller 62 corresponds to the back surface of the band-shaped member 100 and the reinforcing ribs of the band-shaped member 100. 102 has a small-diameter roller that supports the tip, and a large-diameter roller having a width that can be inserted between adjacent reinforcing ribs 102 and 102 of the belt-like member 100, and is sandwiched between the inner guide roller 61 and the outer guide roller 62. The strip member 100 is prevented from moving in the width direction immediately before the joining mechanism 4.

  In this case, the outer guide roller 62 can be adjusted by fixing the fixing position in the radial direction of the molding frame 2 to the mounting member 63 through the long hole 64a, and the fixing position in the axial direction can be adjusted by the shaft support portion of the adjusting member 64. Adjustment is possible by moving the support shaft 622 along 64b and fixing it to the shaft support 64b.

  In the above-described embodiment, the case where the rehabilitated pipe S is manufactured by the belt-like member 100 shown in FIG. 15 has been described, but the embodiment is not limited to such a belt-like member 100.

  For example, although not shown in detail, it may be a band member with a reinforcing material in which a reinforcing material made of metal having a W-shaped cross section is disposed across adjacent reinforcing ribs 102 or a plurality of reinforcing ribs. I do not care.

  Further, as shown in FIG. 16, a belt-like member 100 </ b> A including a belt-like body 110 and a connector 120 that joins the adjacent belt-like bodies 110 and 110 may be used.

  The band-shaped body 110 is formed by extruding a flexible synthetic resin, and a plurality of T-shaped reinforcing ribs 112 are located on the back surface of the band-plate-shaped substrate 111 so that the ends thereof are parallel to the substrate 111. Is provided. And the joint ditch | groove 113 is continuously formed in the both-sides edge part of the board | substrate 111 along a longitudinal direction, respectively.

  On the other hand, the connector 120 is formed with a pair of joint convex portions 121 that can be joined to the joint concave portions 113 and 113 at both side edges where the adjacent strips 110 and 110 are abutted, along the longitudinal direction.

  Thus, the leading edge side joining recess 113 of the preceding strip 110 and the leading edge joining recess 113 of the following strip 110 in a state where the front end edge and the trailing edge of the strips 110, 110 adjacent to each other face each other. The strips 110 and 110 adjacent to each other can be connected via the connector 120 by fitting the connector 120 from the inner peripheral side of the strip 110 and joining them.

  In the above-described embodiment, the inner link frame 22 and the outer link frame 23 are rotatably connected via the connecting shaft 24 to form the link body 21, and the plurality of link bodies 21 are sequentially connected. Although the molding frame 2 formed in a substantially annular shape is illustrated, a plurality of arcuate frames that are paired in the front-rear direction may be connected to form a molding frame. In this case, the guide roller 3 is rotatably supported by the front and rear arcuate frames at intervals in the circumferential direction.

  Further, the joining mechanism 4 includes an inner surface roller 42 and an outer surface roller 43, sandwiching adjacent spiral belt-like members 100, 100, and fitting and joining the joint concave portion 105 and the joint convex portion 103, so that the rehabilitation pipe Although the case where S was manufactured was illustrated, it is not limited to such a joining mechanism 4. For example, although not shown in detail, the following belt-shaped member is sandwiched and forcibly fed by a pinch roller composed of a pair of rollers, and the first guide roller that reaches first is wound in a spiral shape with the existing pipe.
