Backfill Material The backfill material used in this embodiment may be cement-based or synthetic resin-based, but is not limited thereto (for example, use of fine sand). Cement-based and synthetic resin-based materials exhibit fluidity during filling and subsequently solidify to exhibit a predetermined strength. It preferably has foamability. More specifically, the cement-based backfill material is mainly composed of cement material / water (cement milk / paste above) and other suitable admixtures, particularly a foaming agent / gas generating agent (for example, aluminum which exhibits foamability). (Powder etc.) and the like are added, and the viscosity is adjusted so as to have an appropriate self-holding force. Alternatively, a mortar obtained by adding fine sand to a cement paste material can be used. Also in this case, a similar admixture material is appropriately added. A so-called foamable synthetic resin is used as the synthetic resin-based backfill material. The foamable synthetic resin backfill material has an adhesive property in an uncured state and forms a liquid material. Also, it exhibits the required strength after curing. In this foamable synthetic resin backfill material, the timing and degree of foaming are appropriately adjusted by a reaction accelerating / suppressing agent, a foaming agent, and a foam stabilizer. Usually, the reaction start time is delayed. Further, the viscosity and tackiness are adjusted by a thickener so that the viscosity does not hang down below the lining pipe R and the tackiness is such that it adheres to the groove surface of the lining pipe R.
In-situ foamed plastics such as foamed polyurethane, foamed urea resin, foamed phenolic resin, etc. are suitable as such expandable synthetic resin.

Lining Construction Method The above-mentioned lining construction apparatus S is applied and operated for lining construction in the pipe as follows. 23 to 26
Shows an outline of the lining construction work of one aspect thereof. In this construction work, an example of application to a sewer pipe P having a circular cross section as an underground buried pipe is shown. In the figure, Q1 is an upstream human hole and Q2 is a downstream human hole. As shown in FIG. 23, in the above-ground portion, the unwinding device T with the turntable around which the belt-shaped member 500 is wound is arranged on the upstream manhole Q1 side.
A hydraulic drive source G is arranged on the downstream side human hole Q2 side. Construction is done from the upstream side to the downstream side. Further, the backfill material supply device K (K1) is arranged near the front of the main lining construction device S as described above.

Carrying the lining construction device S into the pipe P
The main lining construction device S is carried into the pipe P to be rehabilitated through the manhole Q1. The molding frame 1 of the present construction apparatus S can be assembled, and it is easy to carry it into the human hole Q1. That is, the opening of the human hole Q is small, but 1
The carrying-in can be easily carried out by removing the bolts and nuts between the back plates 17 of the one inner link body 10B or by removing the adjusting bolt 31 of the one circumferential length adjusting mechanism 2. After the carry-in, the bolts / nuts or the adjusting bolts 31 are attached again in the human hole Q to form the molding frame 1
Is an annular body. Further, the joining mechanism portion 7 can be attached to the molding frame 1, so that it can be easily attached on site. At this time, the backfill material injection mechanism 8 and the rotary joint device 9 are also mounted at the same time. Regarding the hydraulic system as the working pressure fluid system, the hydraulic pipe 600 is connected through the hydraulic rotary joint portion 9A of the rotary joint device 9, and the hydraulic pipe 600 is further connected to the hydraulic drive source G at the ground portion. To be done. Regarding the backfill material system, the end of the injection pipe 95 of the backfill material injection mechanism portion 8 is connected to the backfill material rotary joint portion 9B. The backfill material F is not supplied from the backfill material supply device K.

Adjustment of Perimeter of Molding Frame 1 The perimeter of the molding frame 1 in the present construction apparatus S is adjusted. That is, the adjusting bolt 31 of the peripheral length adjusting mechanism 2 of the molding frame 1 is rotated to adjust the interval γ. Normally, the adjusting bolt 31 is placed in the neutral state. This defines the circumferential length of the lining pipe R to be molded. Further, the inner and outer gap holders 41, 4 of the gap holding mechanism 3

When the adjustment of is completed, the bolt 4
3 is rotated to draw the inner and outer spacing holders 41 and 42 toward each other and bring them into contact with the tapered surface 40a of the tapered plate 40.

Lining Construction The lining construction is performed based on the following procedure. (1) Pull the belt-shaped member 500 into the human hole Q1,
The pre-assembled main construction device S is driven inside, and the belt-shaped member 500 is driven around the molding frame 1 several times (about three times) along with the driving of the joining mechanism portion 7, and the lining pipe (this Referred to as a starting lining tube) Ro is prepared. The circumference of the inner surface of the starting lining pipe Ro is equal to the circumference of the construction apparatus S. Further, the starting lining pipe Ro holds the circular shape in a natural state where no restraining force is applied due to the elasticity of the belt-shaped member 500. (2) In the human hole Q, the joining mechanism part 7 is attached to the main construction device S in which the starting lining pipe Ro in the above state is assembled.
The mounting portion of the molding frame 1 to which is attached is brought into a center-folded state through the link, and the joining mechanism portion 7 is pulled in in the radial direction together with the starting lining pipe Ro. At this time, the outer end of the feed roller 73 of the joining mechanism portion 7 is placed on the circumference of the starting lining pipe Ro in a natural state, or slightly protrudes outward from the circumference. In this way, the lining pipe (this is referred to as the initial lining pipe) Ri is formed as a pre-stage before being inserted into the pipe P. It is convenient to use a shape-retaining tool in the operation of retracting the mounting portion. FIG. 24 shows an example of this shape-retaining tool J.
The shape-retaining tool J includes a circular arc plate (pressing plate) 120 that substantially exceeds 180 °, end screw hole members 121 fixed inside both ends of the circular arc plate 120, and these screw holes. Two fixing screw rods 123 interposed between the members 121 via a central screw hole member 122, and a retracting screw rod 124 screwed into a screw hole of the central screw hole member 122,
Consists of. More specifically, the arc plate 120 is made of a steel plate having an arc shape, has some elasticity, and its outer surface abuts on the inner peripheral surface of the molding frame 1. End screw hole member 12
1, a screw hole 121a is screwed, and a fixing screw rod 123
One of the screws 123a is received. Central screw hole member 1
A screw hole 122a for receiving the other screw 123b of the fixing screw rod 123 is screwed in 22, and a screw hole 122b into which the screw 124a of the retracting screw rod 124 is screwed is screwed in the center thereof. Screw 1 for fixing screw rod 123
23a and 123b are reverse screws. The other end of the pull-in screw rod 124 serves as a mounting portion 124b to the molding frame 1 or the joining mechanism portion 7. As shown in FIG. 24 (b), the attachment portion 124b of the pull-in screw rod 124 has a disc shape, and the attachment mechanism portion 7 is attached to the pull-in screw rod 124 and the joint mechanism portion 7. Box 53
It is rotatably engaged with the reaction force receiving member 125 provided in a protruding manner from the back surface of the. Regarding the use of the shape-retaining tool J, the shape-retaining tool J is placed inside the molding frame 1 in a predetermined state, and first, the fixing screw rod 123 is rotated to expand the diameter of the arc plate 120. Then, it is pressed against the inner circumference of the molding frame 1 to be fixed. In addition, the attachment portion 124b is attached to the joining mechanism portion 7.
The threaded rod 124 for engagement that is rotatably engaged is rotated to retract the joining mechanism portion 7 in the radial direction, and the link portion of the mounting portion of the molding frame 1 is set to the center-folded state. The shape-retaining tool J is not limited to the above-described aspect as long as it has equivalent functions. (3) The main construction apparatus S in this state is drawn into the pipe P and temporarily fixed at an appropriate position of the pipe P (usually the inlet end of the pipe). At the time of this withdrawal, since all of the construction apparatus S including the initial lining pipe Ri is in a state of being contained within the inner diameter of the pipe D, there is no particular difficulty in the withdrawal operation.
After that, the shape-retaining tool J is removed. Next, the back-filling material injection mechanism 8 is connected to the back-filling material supply device K through the back-filling material rotary joint 9B to prepare for the back-filling material supply. (4) The construction device S is driven to manufacture the lining pipe R. That is, the feed roller 73 of the feed mechanism 52 is
Of the pipe wall and receives the reaction from the pipe wall to rotate the construction device S. In addition, the inner and outer surface rollers 5 and 6 of the joining mechanism portion 7 are rotationally driven, and by the clamping force between the inner surface roller 5 and the outer surface roller 6, at the closing portion H of the belt-shaped member 500, the joint structure connects the initial lining pipe Ri. The belt-shaped members 500 that are newly supplied are joined. The molding frame 1 moves on the inner surface of the molded lining pipe R by the rotation of the guide roller 4. Thereby, the strip member 500 is spirally wound, and the lining pipe R is manufactured. Then, the formed lining pipe R is left,
The entire construction apparatus S revolves in the pipe circumferential direction and advances in the pipe axis direction while a new strip-shaped member 500 is added. In this process, as the molding frame 1 rotates,
The force applied to the circumferential length adjusting mechanism 2 is received by the spacing holding mechanism 3, and no excessive stress is generated in the circumferential length adjusting mechanism 2. (4a) In this step, in the joining mechanism section 7 of the present construction device S, the lining pipe R is bent inward to form a concave curved surface,
With the passage of the joining mechanism portion 7, it returns to a circular shape, that is, a convex curved surface, and further, the running tube R left behind returns to a circular shape due to its elasticity. That is, FIG. 25 and FIG.
As shown in FIG. 6, the portion of the lining pipe R gripped by the joining mechanism portion 7 receives a pressing force toward the center via the feed roller 73 and the joining mechanism portion 7, and becomes a concave curved surface (A). However, as the distance from the joining mechanism portion 7 in the circumferential direction and the depth (axial) direction increases, the lining pipe R gradually becomes a convex curved surface (B) due to its elasticity. In this case, convex curved surface (B)
Is closely attached to the wall surface of the pipe P or is as close to the wall surface as possible. From a desirable mode,
A symmetrical shape is taken with a line y passing through a point of 1/2 of the distance x from the inner contact point of the outer surface roller 6 to the inner wall surface of the pipe P (contact point of the feed roller 73) as a symmetry axis. (4b) At the same time, in this step, the backfill material supplying device K is driven to operate the pressure feeding device 100 to operate the hopper 101.
Supplying the backfill material or cement material supplied from
Then, the cement material is injected through the rotary joint device 9 from the injection portion 96 of the injection pipe 95 of the backfill material injection mechanism portion 8 through the rotary joint device 9. The fluid backfill material is discharged into the space of the concave curved surface (A) of the lining pipe R in the inner side of the outer surface roller 6 of the joining mechanism portion 7, and the concave curved surface (A) gradually increases as the joining mechanism portion 7 advances. It changes into a convex curved surface (B) and adheres to the wall surface, whereby the backfill material spreads widely and enters the groove portion 504 of the belt-shaped member 500. As for the backfill material made of expandable synthetic resin, the backfill material supply device K1 is driven to pump up the liquid backfill material in the container 110 with the pump 111, and the supply pipe 98 rotates at a predetermined pressure. A predetermined amount of the expandable synthetic resin backfill material is injected from the injection portion 96 of the injection pipe 95 of the backfill material injection mechanism portion 8 via the joint device 9. The back-filling material is injected into the groove portion 504 of the strip member 500, but due to its adhesiveness, adheres to the surface of the lining pipe R, that is, inside the groove portion 504 of the strip member 500,
It does not hang downward, but solidifies with foaming. (4c) Further, in this step, the strip-shaped member 500 is sequentially supplied from the unwinding device T arranged on the ground. The unwinding device T has a trochanter 6 on a circular track 620 arranged around the opening of the human hole Q1, as shown in FIG.
A rotary table 622 is rotatably provided via the rotary table 21, and a winding cylinder 623 around which the belt-shaped member 500 is wound so as to be able to be drawn out is rotatably supported on the rotary table 622. (5) The foamable backfill material injected is filled between the pipe D and the lining pipe R manufactured, and the required strength is exhibited by solidification together with foaming of the backfill material, The lining pipe R and the pipe D are integrated through the backfill material. That is, the cement-based backfill material is densified and solidified in the groove portion 504 by the expansion action of the foaming agent, so that the supplementary rigidity of the lining pipe R is increased. Further, the backfill material of the groove 504 is fixed to the inner wall surface of the pipe P, so that the pipe P and the lining pipe R are integrated. Further, even when the backfill material is a foamable synthetic resin adhesive material, it firmly adheres to the concrete pipe D,
With respect to the synthetic resin lining pipe R, the concave groove, that is, the groove portion 504 of the belt-shaped member 500 is filled, and is restrained in the spiral groove portion 504. Are integrated. (6) When the lining pipe R is constructed over a predetermined length of the pipe D (usually the entire length section from the human hole Q1 to Q2),
The construction device S is removed. (6a) Prior to the removal of the present construction device S, the rotary joint device 9 removes the back-filling material rotary joint portion 9B. That is, the injection pipe 95 is separated from the back-filling material rotary joint portion 9B, and the rotary joint 84 in the back-filling material rotary joint portion 9B is reversely rotated to loosen the screw to remove the rotary joint 84 from the injection joint pipe 83. Next, the fixing nut 87 is loosened and removed, and the injection joint pipe 83 is pulled out from the rotary joint device 9. The backfill system is cleaned as soon as possible. Further, the pipe 77 is removed from the rotary joint device 9 even if it is attached to the working pressure fluid system (hydraulic system).

By having the, the removal work is easily performed.
The construction apparatus S can also be divided as described above, and can be easily carried out to the outside through the manhole Q. With the above, the construction work of the present embodiment is completed. As described above, according to the lining construction of this embodiment, it is possible to form the lining pipe R in the full cross section of the pipe P as the molding of the lining pipe R progresses, without causing cross-sectional loss. At the same time, a composite pipe can be obtained by integrating the pipe P and the lining pipe R by solidifying the solidifying filler that has been injected at the same time, so that economical construction can be achieved as a whole. Further, the water blocking property is improved by the solidification of the backfill material. Further, since the backfill material is injected at the same time when the lining pipe R is formed, the construction efficiency is dramatically improved as compared with the conventional method in which the filling operation is performed later. Further, according to the rotary joint device 9 of the present embodiment, since the working pressure fluid system (hydraulic system) and the backfill material system have a coaxial structure, the rotary joint device is downsized and the installation space is reduced. Since the backfill material-type injection joint pipe 83 passes through the axial center of the hydraulic rotary joint portion 9A, it is possible to secure a flow passage cross section having a diameter as large as possible and supply a large amount of backfill material. it can. Also,
Since the back-filling material rotary joint portion 9B can be removed from the rotary joint device 9 by a simple operation, a quick cleaning operation can be performed on the solidified back-filling material after the lining work is completed or during the interruption of the work. be able to. Thereby, smooth lining construction work can be realized. The above-mentioned lining construction was shown to be applied to a pipe with a circular cross section, but the application to an oval cross section or a horseshoe cross section is performed according to the above. This lining work is also applied to a rectangular cross section pipe (see Fig. 27). There is no substantial change in the construction device S. There is substantially no change in the shape-retaining tool J, except that the portion of the circular arc plate 430 that abuts the molding frame 1 is changed to be similar to the lower half of the rectangular pipe. Prior to charging into the pipe, the band-shaped member 500 is wound around the molding frame 1 and a shape-retaining tool is attached to obtain an initial lining pipe Ri having a predetermined shape.
Then, the initial lining pipe Ri is drawn into the pipe and the construction is performed according to the above. When the joining mechanism 7 reaches the corner, the link of the attachment portion of the molding frame 1 follows the change of the corner along the shape. This embodiment includes the following aspects. The band-shaped member is not limited to the one shown in the figure. What is essential is that it has elasticity and both side edges engage with each other in a fitting manner. The joining mechanism section 7 is not limited to hydraulic drive, and a pneumatic motor can be adopted.

(Effects of this Embodiment) According to the lining work carried out by using the lining work device of this embodiment, a special expanding operation can be performed by using the molding frame having the usual flexibility. It is possible to form the lining pipe in the full cross section of the pipe with the progress of the molding of the lining pipe without causing any problems, and without causing cross-sectional loss and at the same time, the solidification of the solidified backfill material injected. A composite pipe can be obtained by integrating a pipe and a lining pipe by connection, and economical construction can be achieved as a whole. Further, the water blocking property is improved by the solidification of the backfill material. Further, since the backfill material is injected at the same time when the lining pipe is formed, the construction efficiency is dramatically improved as compared with the conventional method in which the filling operation is performed later. Furthermore, according to the rotary joint device of the present invention, since the working pressure fluid system (hydraulic system) and the filler system are coaxially arranged, the rotary joint device can be downsized, and the installation place can be saved. Moreover, the mounting becomes easy. In addition, since the backfill material injection joint pipe passes through the shaft center of the rotary joint for working pressure fluid (hydraulic pressure), the cross section of the flow path with the largest possible diameter can be secured, and a large amount of backfill material can be supplied. be able to. Also, since the rotary joint part for backfill material can be easily removed from the rotary joint device, a quick cleaning operation can be performed on the solidified backfill material after the lining work is completed or during the interruption of the work. This contributes to the improvement of construction efficiency.

It is guided to the pushing device 265 of the driven feed roller 207 via. Hereinafter, one form example (first example) of the construction method will be described in the order of steps. (1) The lining construction device S1 is carried into the human hole Q1. The device S1 is connected to the hydraulic drive G and the pneumatic drive source H. At this time, in the driven feed mechanism section B, the pushing device 2
The driven feed roller 7 is retracted by operating 65. (2) In the human hole Q1 of the pipe P, the joining mechanism portion 205 of the device S1 is driven, and the belt-shaped member 500 drawn from the ground portion is wound around the molding frame 1 several times (about three times), and the lining is performed. Pipe (this is called the starting lining pipe)
Create Ro. (3) In this state, the outer peripheral regulation frame body 209 is mounted. That is, when fitting the divided outer peripheral regulation frame 209 to the starting lining pipe Ro, the ring-shaped brim portion 282b of the restraining roller 282 is fitted into the groove 504 of the belt-shaped member 500, and the end portion Bolts and nuts 285 are attached to the connecting plates 284 and the nuts are tightened to press the main body 282a of the restraining roller 282 against the surface of the starting lining pipe Ro.

The injection part 271 is located behind the outer peripheral regulation frame 209, and the injected backfill material F does not touch the frame 209. (5b) Furthermore, in this step, the strip member 500 is sequentially supplied from the unwinding device T arranged on the ground. (6) The lining pipe R having a certain length (usually about 1 m) is manufactured by the above steps (rotating pipe). Then, the brake device 265 of the guide mechanism is operated to drive the driven roller 20.

To Φ. At this time, the driving roller 206 is in an idling state.
In this operation, since the outer peripheral regulation frame 209 is mounted around the molding frame 201, the bulging diameter of the lining pipe R is prevented at this portion. FIG. 28 shows this state. That is, the spread of the belt-shaped member 500 is restricted by the inner and outer rollers 203 and 204 in the vicinity of the joining mechanism part 205, but otherwise spreads immediately by slippage at the joint part and spreads until it is constrained by the wall surface of the pipe P.

In this construction mode, the diameter of the lining pipe R is increased with the progress of the self-rotating pipe, and the process (7) is reached. Thus, according to this construction mode, the lining pipe R having a continuously expanded diameter can be obtained without the step (6) of the first example.

Lining Construction The lining construction method by the present lining construction apparatus S3 is performed in accordance with the above-described second embodiment with a diameter expanding action. For the outline of the construction work, refer to FIG. 41. Hydraulic piping 60
0 is connected to the hydraulic motor 420 of the joining mechanism section 405 and the hydraulic motor 432 of the drive wheel 406a of the main drive mechanism section 406. When the drive wheel 406a of the main feed mechanism 406 is pneumatically driven, it is connected to the air pipe 610. In this lining construction, a continuous diameter expansion operation is performed as the lining construction device S3 advances, and at the same time, backfill material is injected. More specifically, by driving the joining mechanism portion 405 of the present device S3, the belt-shaped member 500 is joined by the sandwiching action of the inner surface roller 403 and the outer surface roller 404, and along the inner circumference of the molding frame 401. The outer circumference of the attached guide roller 402 is regulated, and the guide roller 402 is spirally folded inward. At the same time, the driving wheel 406a, which is brought into contact with the pipe wall of the pipe P by the drive of the main feed mechanism 406, receives a reaction force from the wall surface due to the rotation thereof and applies a feeding force to the device S3, thereby rotating the device S3. Eggplant
The driven wheel 406b and the driven feed mechanism unit 407 are the devices S3.
Smooth rotation. As a result, the belt-shaped member 500 is spirally wound by the device S3, and the lining pipe R is formed under the regulation of the outer circumference. The previously expanded lining pipe R is fixed to the pipe wall P, and the lining pipe R formed by the present device S3 is initially small in diameter due to the constraint of the forming frame 401 and then the guide roller 402. As the apparatus S3 progresses, the molding frame 1 and the guide roller 40
It is released from the constraint of 2 and gradually expands in diameter. That is, the belt-shaped member 500 is fed by a predetermined feeding force and feeding speed by the rotation of the inner and outer surface rollers 403 and 404 by the joining mechanism portion 405, but the present device S3 is a drive wheel that abuts on the pipe wall of the pipe P. Since the rotation speed is kept constant by 406a and is slower than the feeding speed of the belt-shaped member 500, a shearing force is generated between the belt-shaped members 500 of the lining pipe R, and the displacement (slip) at the joint portion is caused. And cause a diameter expansion effect. This diameter expansion is based on this device S3
By controlling the feeding speed of the belt-shaped member 500 by the joining mechanism portion 405 under a constant rotation forward speed of
Obtain a stable expanded state. In order to know the diameter expansion state, an appropriate detector is used to detect the diameter expansion angle, and the feeding speed is controlled based on the detected value. Since the rotation of the device S3 is performed by a plurality of drive wheels 406a that are hydraulically driven,
Since a stable rotational force is obtained and the driven wheel 406b can be biased to the pipe wall of the pipe P, the pipe wall conforms to the unevenness or the non-circular shape of the pipe wall, and a stable pipe-making operation is obtained. On the other hand, during this time, the backfill material is injected from the backfill injection tube 440. That is, the backfill material supply device 45
The liquids A and B supplied from 0 are discharged from the injection part 441 through the rotary joint 443 and the mixing gun 442 to the surface of the lining pipe R in the middle of the diameter expansion. This backfill material enters the groove 504 of the strip-shaped member 500 that constitutes the lining tube R, swells with the passage of time, and then hardens.
As described above, since the lining pipe R can be stably expanded in diameter, the discharge position of the backfill material is also fixed and the position adjustment is easy. The injection pipe 440 is not damaged. In addition, in this embodiment, it is free to adopt the aspect of the previous embodiment with the backfill material.

(Effects of this Embodiment) By controlling the feeding speed of the belt-shaped member 500 at a constant rotational forward speed of the construction apparatus S3, a stable expanded state can be obtained. Since the lining pipe R has a stable expanded diameter state during the injection operation of the backfill material, the discharge of the backfill material is properly determined, and a good injection work can be performed. Since the construction apparatus S3 regulates the outer circumference, a special regulation frame body is not required as in the second embodiment.

At the same time, the driving wheel 406a, which is brought into contact with the pipe wall of the pipe P by the drive of the main feed mechanism 406, receives a reaction force from the wall surface due to the rotation thereof and applies a feeding force to the device S3, thereby rotating the device S3. Eggplant
The driven wheel 406b and the driven feed mechanism unit 407 are the devices S3.
Smooth rotation. As a result, the belt-shaped member 500 is spirally wound by the device S3, and the lining pipe R is formed under the regulation of the outer circumference. The previously expanded lining pipe R is fixed to the pipe wall P, and the lining pipe R formed by the present device S3 is initially small in diameter due to the constraint of the forming frame 401 and then the guide roller 402. As the apparatus S3 progresses, the molding frame 1 and the guide roller 40
It is released from the constraint of 2 and gradually expands in diameter. That is, the belt-shaped member 500 is fed by a predetermined feeding force and feeding speed by the rotation of the inner and outer surface rollers 403 and 404 by the joining mechanism portion 405, but the present device S3 is a drive wheel that abuts on the pipe wall of the pipe P. Since the rotation speed is kept constant by 406a and is slower than the feeding speed of the belt-shaped member 500, a shearing force is generated between the belt-shaped members 500 of the lining pipe R, and the displacement (slip) at the joint portion is caused. And cause a diameter expansion effect. This diameter expansion is based on this device S3
By controlling the feeding speed of the belt-shaped member 500 by the joining mechanism portion 405 under a constant rotation forward speed of
Obtain a stable expanded state. In order to know the diameter expansion state, an appropriate detector is used to detect the diameter expansion angle, and the feeding speed is controlled based on the detected value. Since the rotation of the device S3 is performed by a plurality of drive wheels 406a that are hydraulically driven,
Since a stable rotational force is obtained and the driven wheel 406b can be biased to the pipe wall of the pipe P, the pipe wall conforms to the unevenness or the non-circular shape of the pipe wall, and a stable pipe-making operation is obtained. On the other hand, during this time, the backfill material is injected from the backfill injection tube 440. That is, the backfill material supply device 45
The liquids A and B supplied from 0 are discharged from the injection part 441 through the rotary joint 443 and the mixing gun 442 to the surface of the lining pipe R in the middle of the diameter expansion. This backfill material enters the groove 504 of the strip-shaped member 500 that constitutes the lining tube R, swells with the passage of time, and then hardens.
As described above, since the lining pipe R can be stably expanded in diameter, the discharge position of the backfill material is also fixed and the position adjustment is easy. The injection pipe 440 is not damaged. In addition, in this embodiment, it is free to adopt the aspect of the previous embodiment with the backfill material.

(Effects of this Embodiment) By controlling the feeding speed of the belt-shaped member 500 under the constant rotation and advance speed of the construction apparatus S3, a stable expanded diameter state can be obtained. Since the lining pipe R has a stable expanded diameter state during the injection operation of the backfill material, the discharge of the backfill material is properly determined, and a good injection work can be performed. Since the construction apparatus S3 regulates the outer circumference, a special regulation frame body is not required as in the second embodiment.

(Fourth Embodiment) FIG. 49 shows the overall construction of still another embodiment (fourth embodiment) of the present invention. Further, in the present embodiment, FIGS. 2 to 16, 23 to 27,
50 and 51 are incorporated. In the fourth embodiment,
This is the same as the construction method / apparatus of the first embodiment except that the injection function / structure of the backfill material is omitted. That is, the lining device S4 of the fourth embodiment does not have the back-filling material injection mechanism (8) and the back-filling material supply device (K, K1) that the lining construction device S of the first embodiment has. . In the fourth embodiment, the same members as those in the first embodiment are designated by the same reference numerals, and the functions thereof are completely the same as those in the first embodiment, and therefore the description thereof will be omitted.

Lining construction device S4 (FIGS. 49 and 2)
(See FIG. 16) The present lining construction device S4 includes a forming frame 1 (including a circumferential length adjusting mechanism 2 and a spacing holding mechanism 3), a guide roller 4, and a joining mechanism section 7 including an inner roller 5 and an outer roller 6. That is, the present device S4 is obtained by omitting the back-filling material injection mechanism 8 and the back-filling material supply devices K and K1 from the configuration of the lining construction device S of the first embodiment. The hydraulic system of the rotary joint device 9C is used, or a known mechanism is used.

Lining construction (see FIGS. 23 to 27) The lining construction method by the lining construction apparatus S4 is the same as that of the first embodiment described above, and no backfill material is injected.
The outline of the construction work is referred to FIG. 23. Construction site (Fig. 2
In 3), the backfill material supply device K is not prepared. The hydraulic pipe 600 is connected to the drive system of the apparatus S4 when the apparatus S4 is carried into the pipe P. The lining construction is performed in the following procedure according to the procedure of the first embodiment. (1) ~
(3): Follow steps (1) to (3) above. (4): Follow the process of (4) above. (4a): Same as the above step (4a). (4b): Same as the above step (4c). (5): Follow steps (6) and (6b) above. In summary, prior to construction, after winding the strip-shaped member 500 around the molding frame 1, the attachment part of the joining mechanism part 7 is folded inward with its link, and the whole of the device S4 corresponds to the cross section of the pipe P. Then, after that, it is loaded into the pipe P. By driving the construction device S4, the joints that are in contact with each other by the sandwiching action of the outer surface roller 6 and the inner surface roller 5 of the joining mechanism portion 7 are engaged with each other at the closed portion of the belt-shaped member 500. The outer surface roller 6 is engaged with a groove 504 formed on the outer surface of the belt-shaped member 500, so that the belt-shaped member 500 newly supplied.
At the same time, the joint mechanism 7 is moved forward at a predetermined pitch in the pipe axis direction, and the joining mechanism 7 is always located at the closed portion. As a result, the lining construction device S4 is revolved as a whole, and the belt-shaped member 500 is continuously closed to produce a pipe. At this time, the joining mechanism 7
The link body of the molded frame 1 attached to is subjected to a pressing force toward the center via the contact roller 73 that contacts the tube wall, and is in a state of being bent in the middle. The lining pipe R wound around the molding frame 1 is separated from the pipe wall only at the link portion of the attachment portion of the joining mechanism portion 7, and the remaining portion spreads outward due to the elasticity of the belt-shaped member 500 and is in close contact with the pipe wall. keep. With the progress of the formation of the lining pipe R, the lining pipe R rearward from the joining mechanism portion 7 gradually returns from the concave cross section to the convex cross section and comes into close contact with the pipe wall over the entire circumference. As described above, according to this lining construction, the lining pipe R can be formed over the entire cross section of the pipe P as the molding of the lining pipe R progresses, and the cross sectional loss does not occur, which is economical. You can achieve the perfect construction. In this embodiment, the following design changes are made in addition to the points pointed out in the first embodiment. In the joining mechanism section 7, an electric motor can be adopted in addition to the hydraulic drive / pneumatic motor. When adopting a pneumatic motor, the rotary joint is still used, but when adopting an electric motor, a rotary brush is adopted instead of the rotary joint. Alternatively, the manual mechanism is not excluded, and the gear mechanism 3
The rollers 5 and 6 are driven by a handle operation via 1.

(Effect of this Embodiment) According to this embodiment, by using the molding frame 1 having the usual flexibility, the pipe culvert can be easily operated without any special diameter expansion operation. The lining pipe R can be formed over the entire cross section of P, and economical construction can be achieved without causing cross-sectional loss.

(Fifth Embodiment) The present embodiment is characterized in that the injection of the backfill material is omitted in the lining construction of the third embodiment. The fifth embodiment will be described with reference to FIGS. 45 to 48. That is, the lining device S5 of the fifth embodiment is the backfill material injection mechanism (40) which the lining construction device S3 of the third embodiment has.
8) It does not have a backfill material supply device (450, K, K1). In the fifth embodiment, the same members as those in the third embodiment are designated by the same reference numerals, and the description thereof will be omitted.

The lining construction device S5, that is, the present lining construction device S5 includes a molding frame 401, a guide roller 402, a joining mechanism portion 405 including an inner surface roller 403 and an outer surface roller 404, and a drive wheel 406a.
And a driven wheel 406b, and a driven feed mechanism section 407 and a driven feed mechanism section 407.

Lining Construction The lining construction method by the present lining construction apparatus S5 is performed in accordance with the above-described third embodiment with a diameter expanding action. For the outline of the construction work, refer to FIG. 41. Hydraulic piping 60
0 is connected to the hydraulic motor 420 of the joining mechanism section 405 and the hydraulic motor 432 of the drive wheel 406a of the main drive mechanism section 406. When the drive wheel 406a of the main feed mechanism 406 is pneumatically driven, it is connected to the air pipe 610. In this lining construction, a continuous diameter expansion operation is performed as the lining construction device S5 advances. More specifically, the belt-shaped member 500 is joined by the sandwiching action of the inner surface roller 403 and the outer surface roller 404 by the driving of the joining mechanism portion 405 of the present device S5, and along the inner circumference of the molding frame 401. Guide roller 402 attached
It is spirally folded inward under the regulation of the outer circumference.
At the same time, the driving wheel 406a, which is brought into contact with the pipe wall of the pipe P by the drive of the main feeding mechanism 406, receives a reaction force from the wall surface due to the rotation thereof and applies a feeding force to the device S5, thereby rotating the device S5. Eggplant The driven wheel 406b and the driven feed mechanism 407 smoothly rotate the device S5. As a result, the belt-shaped member 500 is spirally wound by the device S5,
The lining pipe R is formed under the regulation of the outer circumference. The previously expanded lining pipe R is fixed to the pipe wall P, and the lining pipe R molded by the present device S5 is initially small in diameter due to the constraint of the molding frame 401 and then the guide roller 402. As the apparatus S5 progresses, the constraint of the molding frame 1 and the guide roller 402 is released, and the diameter gradually increases. That is, the belt-shaped member 500 is fed at a predetermined feeding force and feeding speed by the rotation of the inner and outer surface rollers 403 and 404 by the joining mechanism portion 405.
In the present device S5, due to the drive wheel 406a that is in contact with the pipe wall of the pipe D, the rotation speed is kept constant and is lower than the feeding speed of the strip member 500, so that shearing occurs between the strip members 500 of the lining pipe R. A force is generated, which eventually causes slippage (slip) at the joint and causes a diameter expansion effect. As for this diameter expansion, a stable diameter expansion state is obtained by controlling the feeding speed of the belt-shaped member 500 by the joining mechanism portion 405 under the constant rotational advance speed of the present device S5. In order to know the diameter expansion state, an appropriate detector is used to detect the diameter expansion angle, and the feeding speed is controlled based on the detected value.
The rotation of the device S5 is performed by a plurality of drive wheels 406 driven by hydraulic pressure.
Since it is performed by a, stable rotation force can be obtained, and it can be biased to the pipe wall of the pipe P together with the driven wheel 406b, so that it can be adapted to unevenness or a non-circular shape of the pipe wall and can be manufactured stably. A tube action is obtained.

(Effects of this Embodiment) By controlling the feeding speed of the belt-shaped member 500 at a constant rotational and forward speed of the construction apparatus S5, a stable expanded diameter state can be obtained. Since this construction apparatus S5 regulates the outer circumference, a special regulation frame body is not required unlike the second embodiment.

(Still Another Embodiment) A lining construction method and construction apparatus of another embodiment (sixth embodiment) included in the present invention will be described with reference to FIG. 52 shows a schematic front view of the lining construction device, which is equivalent to FIG. This embodiment belongs to the second invention and takes an aspect different from that of the first embodiment. That is, it is a construction mode in which the tubular body to be molded is restored by the elasticity of the belt-shaped member while being subjected to concave deformation, and the back-filling material is injected together with the molding. The lining construction device S6 has a regulation frame 150 having a ring shape smaller than the inner diameter of the pipe P and having a concave portion 150a in the circumferential direction, and is constrained around the regulation frame 150. The molding frame 151 is a ring-shaped body that is flexible and has a link mechanism including the link body 151a, and a guide roller 152 arranged on each shaft portion 151b of the link mechanism of the molding frame 151. The regulation frame 150 has a predetermined width and rigidity, and the molding frame 151 is the molding frame 1 of the first embodiment.
However, in the present embodiment, the guide roller 152 can be rotated in the arrow A direction while being further constrained around the restriction frame 150, the guide roller 152 is arranged on the outer peripheral side of the molding frame 151, and the inner surface of the belt-shaped member 500 is The so-called inner circumference regulation type is adopted. Regulation frame 150 and molding frame 1
The restraint relationship with 51 is made by appropriate means. The molding frame 15 is formed in the groove formed in the regulation frame 150.
An example is a mode in which the shaft rod is pivotally supported by the first shaft portion 151b and the roller body is engaged. Then, according to the first embodiment, the joining mechanism portion 155 including the inner surface roller and the outer surface roller 154 is attached to the molding frame 151. The joining mechanism section 155 is a box body 15 having a gear mechanism.
It is driven by a hydraulic motor (not shown) attached to No. 6, but its mechanism is similar to that of the first embodiment, and therefore its details are omitted. It is the same as having the feed mechanism section and the feed roller (73). In addition, the injection pipe 158 of the back-filling material is arranged side by side behind the joining mechanism portion 155 to form the joining mechanism portion 155.
It is also attached in accordance with the first embodiment, and detailed description thereof will be omitted. The same applies to the backfill material supply mechanism. Although the joining mechanism portion 155 is provided at one location in the illustrated example, it may be arranged at two or more locations, or may be arranged at equal intervals in the circumferential direction. In this case, there is one joining mechanism, and the others have only a so-called sandwiching function. Thereby, the initial bulging of the molded lining pipe is prevented.

In the lining work carried out by using this apparatus S6, the strip-shaped members 500 drawn between the inner and outer rollers of the joining mechanism portion 155 are joined to each other by the joining mechanism portions 155 so that the adjacent strip-shaped members 500 are joined to each other. The lining pipe R is formed by being wound into a circular shape and rotating the forming frame 151. The restriction frame 150 advances integrally with the molding frame 151 without changing the phase. During this molding process, the lining pipe R is shaped so that a part of the lining pipe R is folded into a concave shape in the concave portion 150a of the regulation frame 150.
Since the outer peripheral length of the lining pipe R including this recess is equal to the inner circumference of the pipe P, when the recess is restored by the elasticity of the strip member 500, It comes into close contact with the inner surface. At this time, the feed roller of the feed mechanism is in a state of idling in the recessed portion, but it contacts the wall surface of the pipe P in the side portion as well as in the lower portion to smoothly feed the molding frame 151. Further, in the case of having a plurality of joining mechanism portions 155, the lining pipe R that is initially molded is prevented from bulging and the folding action is facilitated. Then, in the process of forming the lining pipe R, the backfill material is injected from the injection pipe 158, and backfilling work is performed simultaneously. The backfill material is similar to that of the above embodiment, but a lightweight foamable synthetic resin material is preferably applied.

[0079]

According to the present invention, since the backfill material is injected in the process of forming the lining pipe, the injection work can be carried out without problems even if the lining pipe is lengthened. In addition, the lining pipe is formed in the cross-section of the pipe by forming the dent pipe and expanding process in the process of forming the lining pipe. The tube and the tube are integrated with each other, and the tube has great strength.
