からである。BACKGROUND OF THE INVENTION Plastic tubes, such as drainable sewers, are usually made by the tube winding method.
An extruder with a nozzle base is thereby passed by the rotating core, and the thermoplastic flat tape or special-shaped tape delivered from the extruder overlaps and spirals onto the core. Wrapped around. The overlaps are welded together under pressure. To obtain UV resistance, the pipe or sewer is wrapped from a black plastic material, usually polyethylene. Black tubes are disadvantageous as they absorb light and consequently darken, as long as they handle accessible tubes or sewers. This is because it is necessary to enter the pipe or sewer pipe for inspection or maintenance.

要な利点がある。Tube according to the present invention for solving this problem [construction of invention], the plastic tape in pulp plastic-made tube having a inner layer for reflecting light, inner layer of the tube which can enter into the wound It is characterized by being formed by. The inner layer can be welded to the original tube. In this case, a plastic tape that reflects light is used. In the structure handled as a whole, the present invention is based on the following knowledge. That is, if the light-reflecting inner layer is made of, for example, bright yellow plastic, the interior of the black pipe, in particular the pipe or the sewer pipe, can be lightened to a considerable extent. This makes it considerably easier to enter the tube for inspection and maintenance, and nevertheless maintains the UV resistance of the black tube. Here are the important advantages obtained by the present invention.

In this case, not only is the internal space brightened, but electrostatic charge charging is also prevented at the same time, so even if the pipe according to the present invention is used as a gas supply pipe in the middle of the degassing part for storage, there is no danger of explosion. There is no.

The inside of the tube becomes considerably bright while maintaining UV resistance. The inner layer that reflects light is formed by winding a bright yellow plastic tape 4. Furthermore, the inner layer may be configured as a conductive plastic layer in which particles made of a conductive material are embedded.
