されている。As shown in FIG. 2, the straight pipe portion A is formed by spirally winding a tape made of a soft synthetic resin (for example, a soft vinyl chloride resin) and joining adjacent side edges of the wound tape. A series of integrally formed inner layers 2, and a hard synthetic resin formed along the outer peripheral surface of the inner layer 2 on bent tip portions 4a, 4a having a substantially S-shaped cross section and opposite ends in parallel. For example, a strip 4 made of a hard vinyl chloride resin is spirally wound, and the adjacent bent tip end portions 4 of the strip 4 wound are wound.
a and 4a are overlapped with each other and are engaged with each other by movably engaging with each other in the tube axial direction to be connected. An uneven portion is formed along the. The inner layer 2 and the outer layer 3 are formed by simultaneously and extruding a soft synthetic resin tape and a hard synthetic resin strip 4 which are spirally wound and adhered on a tubular body molding shaft (not shown). Further, the hard synthetic resin strips 4 are in a non-adhered state by, for example, being wound while blowing cooling air between the adjacent strips 4 so that adjacent strips do not adhere to each other.

ようにしてもよい。In the space 5 of the concave portion on the surface of the outer layer 3, for example, a coil 6 made of a synthetic resin material such as a polyolefin which does not heat-bond to the strip is simultaneously extrusion-molded while being filled and fitted to the strip 4. The synthetic resin pipe 1 is prevented from bending by blocking the movement of the plastic pipe in the axial direction of the pipe, thereby limiting its inherent flexibility. The coil 6 may be detachably fitted into the space 5, and may be made of hard vinyl chloride extruded at a temperature low enough not to adhere to the strip 4, and may already be extruded. Alternatively, a strip made of synthetic resin or a hard material other than synthetic resin may be used to spirally wind and fit into the space 5 during the molding process of the synthetic resin pipe 1. Alternatively, after the synthetic resin tube composed of the inner layer and the outer layer is once molded, the coil formed of the above-mentioned various materials may be detachably filled and fitted into the space of the outer layer recess in a separate step.

The coil 6 is provided with the recessed space 5 of the outer layer 3 by an arbitrary length from the tubular body formed into the structure of the straight pipe portion A shown in FIG. It has a structure in which it is removed and removed by an appropriate means such as human power or a tool, and since the strip 4 is restored to the state of being movable in the pipe axis direction, the synthetic resin pipe 1 has flexibility in this portion. doing.

The coil 6 fitted in the space 5 is completely designed so as not to fall off during use. The projections 8 and 8 in this embodiment are intended to prevent the coil 6 from coming off temporarily, and the coil 6 can be freely removed by pulling it out with a little strong force, which hinders the formation of the curved tube portion. is not.

直管部を任意に構成できる利点がある。According to the first aspect of the present invention, a flexible curved pipe portion is provided in a necessary portion by removing the coil fitted in the outer layer concave portion even though it is a single synthetic resin pipe. Since it can be formed, it is possible to perform curved pipe construction suitable for the site without preparing a curved pipe separately, and the construction work can be done easily and in a short time. In addition, the straight pipe part where the coil is not removed has a structure that does not easily bend, so it is sufficient to place the straight pipe part in the part where you want to maintain a straight piping state without the need of flexibility, according to the situation of the construction site. There is an advantage that the curved pipe portion and the straight pipe portion can be arbitrarily configured.
