に有用なものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe laying method, and is useful when rehabilitating an old sewer pipe by a pipe-in-pipe method.

施用されている。Therefore, it is necessary to rehabilitate the sewer pipe at a proper time before the sewer pipe cannot be used. As one of the construction methods, there is known a pipe-in-pipe construction method in which a new pipe is inserted and laid in an old sewer pipe. Has been. In this case, it is required to make the inner diameter of the new pipe equal to the inner diameter of the existing sewer pipe as much as possible to secure the conventional water flow rate.Under such circumstances, it is impossible to connect the new pipe within the existing sewer pipe. , The method of inserting the new pipe into the existing sewer pipe while connecting it in the shaft.

（実開昭６２−４１９８２号公報）、挿入作業の容易化
を図っている。In this pipe-in-pipe construction method, the inner surface of the existing aged sewer pipe has a high friction resistance due to its aging, and if a new pipe is press-fitted as it is, a large press-in force is required. Since it is unavoidable that the new pipe becomes buckled, the new pipe buckles and breaks, and the old sewer pipe breaks, it is necessary to insert the new pipe using a carrier truck or wrap a wheeled band around the new pipe, Wheels are attached at regular intervals in the direction (Japanese Utility Model Laid-Open No. 62-41982) to facilitate the insertion work.

しての役目を果たしている）。In this case, the carrier or the wheels are left in the existing old sewer pipe, and a gap is created between the outer surface of the new pipe and the inner surface of the old sewer pipe. This gap is filled with an injecting agent, for example, mortar. However, especially when using a carrier, the new pipe floats on the new pipe in order to prevent the new pipe from floating with the injection mortar and the top of the new pipe coming into contact with the top surface of the inner top of the sewer pipe, resulting in no mortar between them. A stopper is attached (in the case of using the above-mentioned band with wheels, the wheel located at the top of the new pipe functions as a floating stopper).

することになる。Therefore, in the pipe-in-pipe construction method, the distance between the upper end of the inner surface of the existing aged sewer pipe and the new pipe is controlled by the height of the floating stopper, and the height of the floating stopper is reduced. As long as the height is uniform, the extension of the new pipe will follow the top surface of the inner surface of the existing aged sewer pipe in parallel.

満足に下水道管を更生することができない。However, in old sewer pipes, it is often the case that the predetermined natural downflow gradient is not partially maintained due to bending due to uneven subsidence after construction of the pipeline. Therefore, as long as the new pipe is extended to follow the inner surface of the aging sewer pipe that deviates from the natural flow gradient, the new pipe still cannot satisfy the conditions for the natural flow gradient.
Unable to satisfactorily rehabilitate sewer pipes.

る。According to the method of laying a pipe of the present invention, a pipe receiving member and a floating stopper are attached to an inner pipe to be inserted into an existing outer pipe, and the inner pipe is connected to the inner pipe while being connected to the inner pipe. In the method of inserting, the attachment of the pipe receiving member and the floating stopper of each inner pipe or a predetermined number of inner pipes enables adjustment of axial movement of the support shaft through the support shaft and from the inside of the inner pipe. After inserting a series of inner pipes into the outer pipe, the movement adjustment of the support shaft is performed from inside the inner pipe, and the pipe receiving member supported by these support shafts and the floating stopper from the outer surface of the inner pipe. The position of the inner tube with respect to the outer tube is adjusted by adjusting the protruding height, and then the injecting agent is filled between the outer tube and the inner tube. Wheels are used for.

After the insertion of the inner pipe is completed, the movement of the support shaft is adjusted from inside the inner pipe, and the height of the protrusion of the wheel supported by the support shaft and the lifting stopper from the outer surface of the inner pipe is adjusted to tilt the inner pipe. Can be adjusted. Therefore, even if the existing aged outer pipe has a part that has an inverse slope to the natural downward slope, the slope of the inner pipe part at that part is adjusted to a predetermined downward slope, and the old aged outer pipe is replaced. It can be rehabilitated from the viewpoint of natural downflow.

徴とする管の布設方法。1. A method of attaching a pipe receiving member and a floating stopper to an inner pipe to be inserted into an existing outer pipe, and inserting the inner pipe into the outer pipe while connecting the inner pipe to each inner pipe or a predetermined number of pipes. The attachment of the pipe receiving member and the floating stopper of the inner pipe is performed through the support shaft and enabling adjustment of the axial movement of the support shaft from the inside of the inner pipe, and a series of inner pipes in the outer pipe are attached. After insertion, the movement of the support shaft is adjusted from within the inner pipe, and the height of the pipe receiving member supported by these support shafts and the protrusion height of the floating stopper from the outer surface of the inner pipe are adjusted to adjust the outer pipe of the inner pipe. The position of the pipe is adjusted, and then an injecting agent is filled between the outer pipe and the inner pipe.
の布設方法。2. The pipe laying method according to claim 1, wherein the pipe receiving member is a wheel.
