Abstract

PROBLEM TO BE SOLVED: To achieve diameter-expanding operation of a lined pipe and its execution of making long and large by a method wherein a band member to be afresh fed by at least a moved amount of a connection mechanism part is fed into, and mutual joint part of the band members of preformed tubular materials is smoothly moved. SOLUTION: A driven roller 7 is braked by operating a braking device of a guide mechanism part B to fix a main lining execution device. Besides, a pipe end part of a start lined pipe is held by fixing. A connection mechanism part 5 is further driven under that state. A band member is sent into the lined pipe which is preliminarily formed to an automatically manufactured pipe amount or over by driving with a connection roller 20 of the connection mechanism part 5. The lined pipe enlarges its diameter by such an amount that it overcomes engaged force at the joint part. At that time, a main moving roller comes to be of a racing state. Though expansion of the band member is regulated by inside and outside rollers 3, 4 near the connection mechanism part 5, the band member is expanded immediately by sliding at the joint part excepting that, which is expanded until it is restricted by a wall surface of a pipe groove.

The outer surface roller is engaged with the concave groove formed on the outer surface of the belt-shaped member to advance in the pipe axis direction at a predetermined pitch together with the newly supplied belt-shaped member,
The joining mechanism portion is always located at the closed portion. As a result, the present lining construction device is revolved around the whole, and the strip-shaped members are continuously closed to produce a pipe. The plurality of feed rollers function as a whole to hold the center in the pipe of the lining construction device. The main feed roller comes into contact with the wall surface of the pipe, receives a reaction from the wall surface due to the rotation, and imparts a rotational force to the lining construction device, thereby performing the main dynamic rotation of the lining construction device. Other feed rollers, ie, driven feed rollers, facilitate this rotation. In the process of constructing this lining pipe, by feeding a strip-shaped member newly supplied in excess of the amount of movement of the joining mechanism portion, the already formed tubular body, that is, the joint portion between the strip-shaped members of the lining pipe is slid to slide the lining. Expand the tube. This diameter expansion is usually performed until it comes into close contact with the inner wall of the pipe, but it can be stopped before that.

Drive. The joining mechanism portion 5 is rotationally driven, and the belt-shaped member 100 is held by the sandwiching force between the inner surface roller 3 and the outer surface roller 4.
In the closing portion H of the strip-shaped member 100, which is newly supplied by being connected to the starting lining pipe Ro by its joint structure.
Are joined. At the same time, the joining roller portion 20 rotates in the tube circumferential direction and advances in the tube axial direction by the engagement guide action of the ring-shaped flange portion 61 of the outer surface roller 4 and the groove 104 of the belt-shaped member 100. At the same time, the drive mechanism A is also driven,
By the rotation of the main feed roller 6, the device S rotates as a whole along with the rotation of the joining mechanism portion 5 and advances at a predetermined pitch, and the device S moves forward. As a result, the belt-shaped member 100 is spirally wound, and the lining pipe R is constructed with a self-rotating pipe. The lining pipe R
Is equal to the diameter φ of the starting lining pipe Ro.

By doing so, the rotation of the device S is smoothly performed. That is, the first shaft portion 37 is rotationally driven by the rotation of the hydraulic motor 24, and the second shaft portion 38 is rotationally driven via the gears 40 and 41. As a result, the drive sprocket 45 rotates integrally with the shaft portion 38, and the drive roller 6 is rotated via the chain 47 wound around the drive sprocket 45. The drive sprocket 45 and the main feed roller 6 rotate in the same direction, and the inner roller 3 also extends in the same direction. The primary feed roller 6 comes into contact with the wall surface of the pipe D, receives a reaction from the wall surface due to the rotation, and imparts a rotational force to the main lining construction device S, thereby defining the rotation of the main lining construction device S.

Thereafter, the brake device 75 of the guide mechanism section B is operated to brake the driven roller 7, and the main lining construction device S is fixed. On the other hand, the pipe end of the starting lining pipe Ro is fixedly gripped. In this state, the joining mechanism section 5 is further driven. By driving the joining roller section 20 of the joining mechanism section 5, the strip-shaped member 100 is fed into the lining tube R that is already formed in a quantity greater than the amount of the auto-rotating tube, and the engaging force at the joint section is overcome, and that much lining tube is used. R expands its diameter to Φ. At this time, the driving roller 6 is set in the idling state. FIG. 1 shows this state. That is, the spread of the belt-shaped member 100 is restricted by the inner and outer rollers 3, 4 in the vicinity of the joining mechanism portion 5, but otherwise spreads immediately by slippage at the joint portion and expands until it is restrained by the wall surface of the pipe P.
