Conventionally, this type of flexible tube has a spiral groove 1A on the circumferential surface of a plastic tube body 1, as shown in FIG.
are provided. To connect the flexible tubes configured as described above, as shown in FIG. A configuration is adopted in which each is sealed with a sealing tape 3, and then a balco tape 4 is wrapped over it, and both ends are sealed with a vinyl tape 5. The reason for the above configuration is that the spiral grooves 1A of the flexible tubes 10 are in communication with each other. Therefore, when connecting the flexible tubes, if the connected parts are not tightly covered, rainwater, groundwater, etc. will be transmitted through the spiral grooves 1A. This is because there is a risk that the particles may reach the seam of the flexible tube 10 and enter the interior of the flexible tube 10 through the seam.
しかし上記のような構成の接続部分では可撓管
相互を接続するために極めて大きな手間がかかり
また接続するための各種材料が必要である。更に

大きな問題点をかかえている。
However, in the connection portion having the above-mentioned structure, it takes an extremely large amount of effort to connect the flexible tubes to each other, and various materials are required for the connection. Furthermore, since the connecting parts are taped, when multiple flexible tubes are bundled together and buried in the soil, it is necessary to leave enough space between the flexible tubes so that the taping will not be hindered, making it compact. There is a major problem in that it cannot be buried.
本考案は上記従来の問題点を解決する手段とし

As a means to solve the above-mentioned conventional problems, the present invention provides a pair of flexible tubes in which a large number of ring grooves 11A are successively provided on the circumferential surface of a plastic tube 11, and a packing groove 11B is formed between the ring grooves 11A. tube 20,2
A flexible tube connection structure is provided in which a ring-shaped gasket 16 is fitted into the gasket groove 11B at the connecting end of the flexible tube 12, and each of the connecting ends of the pair of flexible tubes 20, 20 is inserted from both ends of the connecting sleeve 12. This is what we provide.

The ring grooves of the flexible tube are each independent, and rainwater or groundwater cannot be transmitted from one ring groove to another. Therefore, in the above connection configuration, even if rainwater or groundwater does not enter the connection sleeve from the outside of the connection sleeve, the rainwater or groundwater is blocked by the ring groove of the flexible pipe.
Furthermore, the ring-shaped gasket at the connecting end of the flexible tubes reliably prevents rainwater and groundwater from entering the interior through the joints between the flexible tubes.

Therefore, in this invention, there are only two types of materials for connection: the connection sleeve and the ring-shaped packing, and the connection requires no effort at all, and it can completely prevent rainwater and underground water from entering through the connection part. Furthermore, since there is no need for taping, when a plurality of flexible tubes are bundled and buried, the distance between the flexible tubes can be reduced, and the flexible tubes can be buried compactly. Also, since the ring groove and packing groove are separate,
The shape of the ring groove does not affect the shape of the seal, and the shape of the seal does not affect the shape of the ring groove.For example, the ring groove can be made deeper and larger to improve the flexibility of a flexible tube. However, there is no need to make the padskin thicker accordingly.
