Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a tube inversion lining method for repairing by inverting and lining a tube on the inner surface of a gas conduit, a water pipe or the like. The present invention relates to various devices used for a so-called non-excavation tube inversion lining method in which all work is performed from only one side when the construction method is performed.

[Prior Art] In a known tube inversion lining method, particularly in the case of a buried pipeline with many bends, one side of the pipeline to be lined is excavated, and an invertor is installed on one inversion start side. Install the winch on the other end of the reversing end,
While pulling the pulling tape inserted in the non-inverted tube with a winch, fluid pressure is applied to the inside of the non-inverted tube to cause it to invert.

However, this construction method has a problem that a working groove is required particularly in the case of a buried pipe, which causes a traffic obstacle when it is performed in a place with a large amount of traffic. In addition, excavating and backfilling the working groove is expensive and troublesome.

From this point of view, the present applicant has proposed a so-called non-excavation tube reversal lining construction method and a device therefor in which, in the case of a buried pipe, the tube lining can be performed only from one side exposed on the ground (special feature: Kaisho 60-141527, Same-62-15
6927, Actual Development Showa 62-107926, Same 62-107927, Same 62-10792
8; 62-107929; Japanese Patent Application No. 63-147549).

[Problems of the Prior Art] However, the above-mentioned non-drilled tube inversion lining method and its device have the following problems.

In the case of JP-A-60-141527, since the tip derivative is operated by a wire, the work is troublesome and requires skill.

Next, in the case of JP-A-62-156927, there is no flexibility in the deformation of the curved portion at the tip, and it takes time to pass through the curved portion in the pipeline.

Next, in the case of the case of Shokai Sho 62-107926, there are two bends in advance, so if you want to fit this bend, you can pass the curved part very smoothly, but if it does not match, it will take time to pass. .

Next, in the case of No. 62-107927, a large number of derivatives must be prepared in accordance with the bend of the pipeline in order to provide a bend in accordance with the bend of the pipeline.

Next, in the case of Japanese Utility Model Laid-Open No. 62-107928, it is difficult to control this derivative when the derivative is long.

Next, in the case of Japanese Utility Model Laid-Open No. 62-107929, the derivative is inflexible and may be difficult to pass depending on the bend.

It is an object of the present invention to provide various devices which are particularly convenient when applied to a place where the entire inner pipe (retracting pipe) is repaired from the branch portion of the main branch of the gas pipe by the tube inverting lining method.

[Means for Solving the Problems] In order to solve the above problems, the present invention proposes a device having the following configuration.

However, before that, the outline of the non-drilled tube inversion lining method will be described.

Usually, when applied in a city gas conduit, in the tube inversion lining of the entire service pipe, a standing pipe rising from the ground to the gas meter is used as the inversion start part.

a. First, when carrying out the construction method, the distance from the inlet of the vertical pipe (reversal start part) to the branch part of the main branch (branch port), the number of bends in the middle, and the distance are measured with a sensor rod. Is input to the controller and the length of the inverting tube is determined based on this data.

b. Next, a thermosetting adhesive (hereinafter referred to as “adhesive”) is injected into the reversing tube, and the reversing tube is sandwiched by pinch rolls to evenly apply the adhesive to the inner surface.

c. Next, the tape is bound to the tip of the reversing tube, and is wound into the reversing device from the tape side.

d. Next, pass the tube for inversion through the ring of the head of the guide rod, and stop the tip of the tube for inversion using the stop ring in the connection port of the inversion start joint attached to the vertical tube.

e. Next, at the same time as applying fluid pressure to the inversion tube,
The inversion tube is inverted from the vertical tube into the inner tube by pushing out the induction rod using the pusher of the induction device.

f. Next, during reversing, when the reversing part of the reversing tube hits the bending part and stops advancing, a rotating machine applies a rotational force for changing the direction to the tip of the guide rod, and at the same time by a pushing machine. A pushing force is applied to release the abutting of the reversing part and allow it to pass.

g. Next, when the reversing tube reaches the branching port (this arrival is known by the distance the reversing tube has entered), stop the guiding device and pull out the guiding rod from inside the reversed tube.

h. Next, insert a heating rod from the inversion start part to near the branch port, connect a hot water circulation pipe to this heating rod and inversion start part, and circulate hot water in the inverted tube to cure the adhesive. And line the inverted tube to the inside of the conduit.

i. Next, pull out the heating rod, insert the fusing rod from the reversal start portion, energize the electric heater at the tip of the fusing rod at the branch port to generate heat, and open the tip of the inverted tube for fusing.

In addition, in order to ensure that the opening of this fusing portion is sufficient, it is possible to insert a ball heater rod and trace the opening with a ball-shaped electric heater to make it sufficiently open.

Although the lining is completed as described above, there is the following lining method (Japanese Patent Application No. 63-147549).

In this lining method, the inversion tube is inverted, reaches the branching port, is advanced a little further, and is inserted into the main branch pipe. Turn it inside again, in this case as well, insert it a little from the branching port and stop it, then insert the sensor rod and search for the branching port, and tap the second inverted tube to this position with the tape bundled at the end Next, insert a heating rod, circulate hot water in the second inverted tube to cure the adhesive on the first inverted tube, and then remove the tape on the second inverted tube. Collect while pulling, and then draw the tape of the first inverted tube to the first inverted tube to the branch port. Since the first inverted tube has already been lined up to this branch port, it is difficult to draw it further. Next, a fusing rod is inserted, and the inverted tube is fusing and opened at the branch port portion as in the previous case.
