である。[Detailed description of the invention] The present invention is a pipe joint for corrugated pipes, in particular, a corrugated pipe that can firmly and easily connect the ends of a pair of corrugated pipes with spiral irregularities formed on their outer peripheral surfaces to prevent liquid leakage. This relates to pipe fittings.

端部間を連結している。 Conventionally, in order to connect the ends of a pair of corrugated pipes without leaking, for example, as shown in FIG. 2, the edges of the pair of corrugated pipes 10a and 10b are butted and joined together, and A packing material 14 is wrapped around the outer circumferential surface of both corrugated tubes near the abutting portion 12, and a strip of metal or the like having an uneven cross-sectional shape that follows the shape of the outer circumferential surface of the corrugated tube is placed on the outside of the packing material. band 1
A sealing material 20 is used to seal each depression 18 on the outer peripheral surface of the corrugated pipes near the butt part 12 of a pair of corrugated pipes 10a and 10b that are butt-joined together as shown in FIG.
The outer circumferential surface near the abutting portion 12 is smoothed, and a packing material 14 is wrapped around the smoothed outer circumferential surface near the abutting portion 12. Furthermore, a smooth material such as metal is wrapped around the outer circumferential surface of the abutting portion 12. A belt-like band 16 is wrapped and tightened to connect the ends of the pair of corrugated pipes.

た。 However, when corrugated pipes, especially corrugated pipes with spiral irregularities formed on the outer circumferential surface, are connected using the above-mentioned conventional connection method, the corrugated pipes may be connected to each other due to the difference in the helical position of the cut end of the corrugated pipes. Since the butted ends of the corrugated tubes do not necessarily match, the solution passing through the corrugated tube from the butt portion 12 through the gap between the outer peripheral surface of the corrugated tube and the packing material 14 tends to leak to the outside, especially inside the corrugated tube. When the solution was passed under pressure, it was difficult to avoid leaking the solution from inside the corrugated pipe to the outside from the above-mentioned connection part.

管中を通しても液漏れを発生させることがない。 In addition, a flange portion extending upright from the inner wall of the joint pipe is interposed between each end surface of the corrugated pipes that are connected to each other, and this flange portion is formed at least in the spiral unevenness formed on the outer peripheral surface of the corrugated pipe. Since the corrugated pipes are provided so as to extend by the height of the waves, no matter where the cut ends of the corrugated pipes are located in the spiral, a packing material is interposed at each end face with the corrugated pipes connected, and this packing material The material is not pressed from the circumferential surface of the corrugated pipe as in conventional connecting means, but is tightened by a connecting bolt in the direction of the center axis of the corrugated pipe via a nut member screwed onto the outer circumferential surface of the corrugated pipe. Because of this, a tightening force is applied toward the butt end of the corrugated pipe, and a tight seal is achieved between the corrugated pipe and the packing material. This prevents liquid leakage even when a pressurized solution is passed through the corrugated pipes connected through the joint.

き、取り扱いが非常に簡単である。 Further, the nut member is screwed onto the outer circumferential surface of the corrugated pipe to protect the outer circumferential surface of the connecting end of the corrugated pipe. Moreover, when installing the nut member, it can be installed by simply screwing it onto the corrugated pipe from the connecting end and turning it, making it extremely easy to handle.

By covering the outer periphery of the container, it is possible to prevent water, sand, etc. from entering from the outside.
