Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lining pipe construction method in a pipe tub, and more particularly to a lining pipe construction method effective in a small diameter pipe tub that an operator cannot enter.
[0002]
[Prior art]
In general, a long profile formed in the shape of a long band having joints on both side edges is continuously supplied into the tube, and while the long profile is spirally wound in the tube, There has been known a construction method in which the joining portions of the long profiles which are in contact with each other are joined to form a lining pipe in the pipe rod.
[0003]
Conventionally, in this lining pipe construction method, it has been proposed that a pipe making apparatus is used to perform a pipe making operation for joining joints that are in contact with each other while spirally winding a long profile (for example, a special technique) (See Kaihei 5-169539).
[0004]
[Problems to be solved by the invention]
However, in a small-diameter pipe rod, since an operator cannot enter the pipe rod, it is difficult to confirm whether or not a pipe-forming operation such as supply of a long profile or joining is performed well. Therefore, even if there is a defective part that needs to be redone, the construction will be completed without being able to grasp it, and the construction accuracy will deteriorate.
[0005]
In addition, during the construction work, even with a slight adjustment of the pipe making equipment, it is possible to grasp the pipe making state by the pipe making equipment even if it is possible to avoid the construction failure and perform good construction. Since this is not possible, such adjustment during construction cannot be performed, resulting in construction failure.
[0006]
The present invention has been made in view of the actual situation, and it is possible to grasp the construction accuracy and to avoid the occurrence of defects during construction and to perform reliable construction in a lining pipe in a pipe. The purpose is to provide a construction method.
[0007]
[Means for Solving the Problems]
The lining pipe construction method in the pipe rod of the present invention for solving the above-mentioned problem is formed in a long strip shape having a joining rib on one side edge and a joining groove on the other side edge , and in the longitudinal direction. A long profile having a plurality of ribs projecting along the inner surface of the long profile is continuously supplied into the pipe rod. While the long profile is sandwiched between the outer surface roller formed with the flange portion fitted between the ribs, the fitting roller composed of the inner surface roller and the outer surface roller moves around the inner surface of the tube rod, The long profile is wound spirally, and the long profile is brought into contact while adjusting the joining position of the joining rib and the joining groove by changing the interval between the flanges by the cylinder provided on the outer roller. contacting a bonding rib and bonding channel This is a construction method in which the lining pipe is formed in the pipe rod, and the pipe forming state is constantly monitored by a camera provided in the pipe rod, so that the joining rib and the joining groove of the long profile are not joined. If there is a construction failure, the cylinder of the outer roller of the pipe making device should be remotely controlled from the hydraulic unit on the ground and adjusted to the specified joint position while viewing the camera monitor image. Thus, the construction failure is avoided and the long profile joining rib and the joining groove are returned to a good construction state again, and the supply state of the long profile by the feeding device and the feeding device deteriorates. In the case where a twist or the like occurs in the camera, the supply state of the long profile by the supply device and the delivery device is adjusted while viewing the image on the camera monitor.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 shows an outline of the overall configuration of the construction method of the lining pipe 20 in the pipe rod 1, FIG. 2 shows a long profile 2 used for the construction, and FIGS. 3 and 4 are used for the construction. The pipe making apparatus 3 is shown.
[0010]
That is, this construction method is a construction method in which the lining pipe 20 is constructed in the pipe rod 1 by the long profile 2, and the pipe making state by the pipe making device 3 is performed by the camera 4 provided in the pipe rod 1. Is constantly monitored.
[0011]
The long profile 2 is formed in a long strip shape, and a plurality of ribs 21 project from the outer surface along the longitudinal direction. In addition, a joining rib 22 having a projecting height lower than that of the rib 21 is provided on one side edge of the long profile 2 along the longitudinal direction. On the other hand, a joining groove 23 to which the joining rib 22 is joined is formed on the inner surface of the rib 21 on the other side edge of the long profile 2 along the longitudinal direction. Then, as shown in FIG. 2B, the lining pipe 20 can be formed by joining the joining rib 22 to the joining groove 23 while winding the long profile 2 in a spiral shape. The long profile 2 is fed into the manhole 11 from the supply device 5 installed on the ground and supplied into the tube 1. Further, a feeding device 6 for stabilizing the supply state of the long profile 2 is provided in the pipe rod 1, and the long profile 2 is supplied deep inside the pipe rod 1 so that the long-distance lining pipe 20 is provided. It is made so that it can be constructed. The delivery device 6 can be operated from the ground by a hydraulic drive unit 61 installed on the ground.
[0012]
The pipe making apparatus 3 includes a plurality of guide rollers 31 arranged at predetermined intervals at a predetermined interval on an annular guide frame 30 and a pair of rotary movements that move around the inner surface of the pipe rod 1 while being rotated by the driving force of the hydraulic motor 32. A fitting roller 33 and a drive wheel 34 are provided. The fitting roller 33 is formed by an inner surface roller 33 a along the inner peripheral surface of the long profile 2 and an outer surface roller 33 b in which a flange portion 331 that fits between the ribs 22 of the long profile 2 is formed. And while the long profile 2 is clamped between the inner surface roller 33a and the outer surface roller 33b, the fitting roller 33 moves around the inner surface of the tube rod 1 so that the long profile 2 is spirally wound. However, the joining rib 22 and the joining groove 23 of the long profile 2 are joined to form the lining pipe 20. In addition, the fitting roller 33 is configured to rotate in a state in which the flange portion 331 of the outer surface roller 33b is fitted between the rib 21 and the joining rib 22 of the long profile 2. A slight gap is provided between the joining rib 22 and the flange portion 331. Therefore, when the position of the flange portion 331 is firmly positioned, the bonding rib 22 and the bonding groove 23 are joined well as shown in FIG. When the position of the portion 331 is not firmly positioned, the joining rib 22 and the joining groove 23 are not joined as shown in FIG. 4B. Therefore, the outer surface roller 33b is provided with a cylinder 332, and by changing the interval between the flanges 331 by the cylinder 332, the joining position of the joining rib 22 and the joining groove 23 can be adjusted.
[0013]
As the camera 4, a self-propelled camera that is widely used for investigation in the tube 1 is used. While this camera 4 moves in the pipe rod 1 in synchronism with the pipe making apparatus 3, the supply state of the long profile 2 and the joining position of the joining rib 22 and the joining groove 23 of the long profile 2 are detected. A photograph is taken and the image is taken on a monitor 41 on the ground.
[0014]
In this construction method, the lining pipe 20 is formed in the pipe rod 1 while constantly monitoring the pipe making state by the pipe making apparatus 3 based on the image of the monitor 41 obtained from the camera 4.
[0015]
Therefore, even in the case of the small-diameter pipe rod 1 where a worker cannot enter, the state of the lining pipe 20 formed in the pipe rod 1 can be grasped from the image of the monitor 41. Therefore, in the case where a construction failure occurs without joining the joining rib 22 and the joining groove 23 of the long profile 2, it is possible to grasp immediately, so that construction failure is prevented and construction accuracy is improved. Can be achieved.
[0016]
In addition, when the joining rib 22 and the joining groove 23 of the long profile 2 are not joined as described above and there is a construction failure, the pipe making apparatus 3 while viewing the image of the monitor 41 of the camera 4. The cylinder 332 of the outer surface roller 33b is remotely operated from the hydraulic unit 35 provided on the ground and adjusted to a predetermined joining position, thereby avoiding a construction failure and joining the joining rib 22 of the long profile 2 again. It can return to the favorable construction state which the groove | channel 23 joins.
[0017]
Further, even when the supply state of the long profile 2 by the supply device 5 and the delivery device 6 deteriorates and a twist or the like is generated in the tube 1, the supply is performed while viewing the image on the monitor 41 of the camera 4. The supply state of the long profile 2 by the apparatus 5 and the delivery apparatus 6 can be adjusted, and stable construction work can be performed.
[0018]
In the present embodiment, two images of the monitor 41 of the camera 4 are required to monitor the joining state of the joining rib 22 and joining groove 23 of the long profile 2 and the supply state of the long profile 2. However, when the inside of the tube rod 1 can be seen through the manhole 11 or when the inside of the tube rod 1 is relatively short and there is no concern about the twist of the long profile 2, the bonding rib 22 and the bonding groove of the long profile 2 are used. 23 may be only an image for monitoring the joining state with the head 23.
[0019]
Also, the position where the camera 4 can take an image is not particularly limited as long as a desired image can be taken without adversely affecting the pipe making work. There may be.
[0020]
Furthermore, in this embodiment, as the camera 4, a self-propelled type that is widely used for investigation in the tube 1 is used, but as described above, a self-propelled type provided separately from the pipe making apparatus 3 is used. It is not limited to the camera 4, and as shown in FIG. 5, a commercially available CCD camera 40 may be fixed to the pipe making apparatus 3. In this case, a commercially available tube survey camera (not shown) may be fixed instead of the CCD camera 40.
[0021]
Furthermore, in the present embodiment, the cylindrical tube rod 1 is described, but the shape of the tube rod 1 is not particularly limited to a cylindrical shape, and as shown in FIG. It may be a type (see FIGS. 6A and 6B), a horseshoe-shaped tube hook 1 (see FIGS. 6C and 6D), or the like. Also, the pipe making device 3 may be a box-shaped device (see FIG. 6 (b)) or a horseshoe shape (see FIG. 6 (d)) matched to the shape of the tube rod 1, As shown in FIGS. 6 (a) and 6 (c), regardless of the shape of the tube rod 1, the pipe-making device 3 having a normal circular shape is used for the box-shaped or horseshoe-shaped tube rod 1. Also good.
[0022]
Further, in the present embodiment, the long profile 2 is formed so as to join the joining rib 22 and the joining groove 23. As shown in FIG. It may be composed of a profile main body 2a having fitting ribs 24 formed thereon and a connector 2b for connecting the profile main body 2a. In this case, by winding the fitting ribs 24 of the profile body 2a side by side in a spiral manner and straddling the fitting ribs 24, the connector 2b is fitted to the fitting ribs 24, A lining tube 20 is formed. At this time, the cylinder 332 of the outer surface roller 33b of the pipe making device 3 is remotely operated from the hydraulic unit 35 provided on the ground while watching the image of the monitor 41 of the camera 4, so that the adjacent profile body 2a can be fitted. The butting state of the rib 24 can be adjusted. Further, when the fitting position of the connector 2b is fixed, the fitting roller 24 and the connector 2b are moved in parallel by moving the fitting roller 34 from side to side while viewing the image of the monitor 41 of the camera 4. It is also possible to adjust the relative position with respect to.
