FIG. 1 is a sectional view showing a corrugated tube connection structure according to an embodiment of the present invention. The corrugated pipe 1 shown in the figure has a smooth inner wall 2 and an outer wall 4 having a spiral protrusion 3.
It has a double-walled structure, and is continuously molded from synthetic resin such as high-density polyethylene resin. Reference numeral 5 denotes a flanged cylinder made of metal, which has female threads 6 formed on its inner periphery, and has bolt insertion holes 8 formed at a plurality of equally angularly spaced locations (for example, six locations) on its flange 7. . Further, the female thread 6 is slightly tapered, and the female thread diameter gradually becomes smaller toward the flange 7 side.

Then, between the end surfaces 1a, 1a of the two corrugated tubes 1, 1 that are butted against each other, and between the flanges 7, 7 of the flanged cylinder bodies 5, 5 screwed to each corrugated tube 1, 1. Bolts 10 are inserted into bolt insertion holes 8, 8 in which the flanges 7, 7 of the flanged cylinder bodies 5, 5 face each other, with an annular packing 9 interposed therebetween.
and a nut 11 screwed into the bolt 10.

このような接続構造は波形管１の口径が500〜100
mmといつた大口径で、波径管１の端面の厚みが３
mm程度以上である場合にとくに有効である。 When the flanges 7, 7 are tightened together using the bolts 10 and nuts 11 in this way,
The tightening force is applied to the protrusions 3 screwed and engaged with the female threads 6 of each flanged cylinder 5, and the corrugated tubes 1, 1 are strongly attracted to each other. The tightening force increases as the nut 11 is screwed into the bolt 10 more strongly. Therefore, the packing 9 is sandwiched between the end surfaces 1a, 1a of the corrugated tubes 1, 1 and is strongly compressed, and the packing 9 and the corrugated tubes 1, 1
The watertightness of the contact portions with the end surfaces 1a, 1a of the corrugated pipes 1a, 1a is reliably maintained, and the watertightness is not easily impaired even when a large external pressure is applied to the corrugated pipes 1, 1. Similarly, the seal 9 is also held between the flanges 7, 7 and is strongly compressed, ensuring that the watertightness of the contact area between the seal 9 and the flanges 7, 7 is maintained.
Moreover, its watertightness is not easily impaired even when a large external pressure is applied to the corrugated pipes 1, 1. In addition, since the female thread 6 of the flanged cylinder 5 has a taper, by screwing the female thread 6 strongly into the protrusion 3, a part of the surface of the female thread 6 will come into close contact with the outer surface of the protrusion 3, and the gap between the two will be reduced. This ensures watertightness between the two. Furthermore, if a sealant is filled between the two, the watertightness will be further ensured.
This type of connection structure has a diameter of corrugated pipe 1 of 500 to 100.
It has a large diameter such as mm, and the thickness of the end face of the corrugated pipe 1 is 3 mm.
This is particularly effective when the diameter is about mm or more.

水密性が保たれるようにしてもよい。 In this embodiment, the packing 9 is attached to the end face 1 of the corrugated pipe 1.
Since it is in strong pressure contact with both a and the flange 7, double watertightness is maintained at the connection between the corrugated pipes 1 and 1, and even if the watertightness of one is impaired, the other will not be damaged. It is possible to maintain reliable watertightness. In addition, in this invention, Patsukin 9
It is not necessarily necessary that the gasket 9 is in close contact with both the end surface 1a of the corrugated tube 1 and the flange 7. For example, the gasket 9 may be interposed only between the end surfaces 1a, 1a of the corrugated tubes 1, 1, so that the gasket 9 and the corrugated tube 1 are in close contact with each other. , 1 end face 1
a, 1a, the seal 9 is interposed only between the flanges 7, 7, and the water tightness between the seal 9 and the flanges 7, 7 is maintained. You can do it like this.

As described above, according to the corrugated pipe connection structure of the present invention, corrugated pipes having spiral protrusions can be reliably connected to each other, and the watertightness of the connected portion is maintained not only at the beginning of connection but also after connection. There is an effect that can be maintained reliably. Furthermore, since the flanged cylinder is attached to the end of the corrugated tube using the protrusions of the corrugated tube, the connecting structure of the corrugated tube according to the present invention is as follows:
There is an advantage that even if the corrugated pipe is cut to a predetermined length at the construction site, it can be used without any inconvenience.
