〈産業上の利用分野〉
本考案にいう合成樹脂管は、主として地中に埋
設して上水管、下水（排水）管、電線・電話線等
のケーブル保護管として用いられる。[Detailed explanation of the invention] <Industrial application field> The synthetic resin pipe referred to in the invention is mainly used as a cable protection pipe for water supply pipes, sewage (drainage) pipes, electric wires, telephone lines, etc. by being buried underground. It will be done.
〈従来の技術〉
旧来この種の地中への埋設管は、主としてコン
クリート製の所謂ヒユーム管や鋳鉄管であつた
が、これらのものは何れも重量が大で、かつ、長
尺のものが出来にくいことから作業性が極めて悪
く、地中への敷設に多大な時間と労力を必要とし
た。この欠点を解決できる新しい管として近年合
成樹脂材料を用いた螺旋管が開発され使用されて
いる。この合成樹脂管は前記ヒユーム管等に比し
て数段軽量であるため運送が容易で、可撓性があ
るため地中への埋設作業が便利であるという利点
を有しているので今日では大いに利用されるに至
つている。<Prior art> In the past, this kind of underground pipes were mainly made of concrete, so-called humid pipes and cast iron pipes, but all of these pipes were heavy and long. Because it was difficult to construct, it was extremely difficult to work with, and it required a great deal of time and effort to lay it underground. In recent years, a spiral tube made of synthetic resin material has been developed and used as a new tube that can solve this drawback. This synthetic resin pipe has the advantages that it is much lighter than the above-mentioned hume pipe, so it is easy to transport, and its flexibility makes it convenient to bury underground. It has come to be widely used.
〈考案が解決しようとする問題点〉
しかしながら、地中への埋設管は、強力な土圧
に耐える必要があり、耐圧性を持たせるために、
管壁を肉厚のものとせざるを得なかつた。<Problem that the invention aims to solve> However, underground pipes need to withstand strong earth pressure, and in order to have pressure resistance,
The tube wall had to be made thicker.
しかし、管壁を肉厚のものとすると、成形材で
ある合成樹脂材料が大量に必要となり、コスト高
とならざるを得ないという問題があつた。 However, when the tube wall is made thick, a large amount of synthetic resin material as a molding material is required, resulting in an increase in cost.
そこで、本考案は、該従来の合成樹脂管が有し
ていた上記問題点を解消し、かつ、合成樹脂管そ
のものが有する利点を最大限に生かし、合成樹脂
材の使用量を少なくし、それでいて耐圧性に秀れ
た全く新しい構造の合成樹脂管を得ようとするも
のである。 Therefore, the present invention solves the above-mentioned problems that the conventional synthetic resin pipes had, takes full advantage of the advantages of the synthetic resin pipe itself, reduces the amount of synthetic resin material used, and The aim is to obtain a synthetic resin pipe with a completely new structure that has excellent pressure resistance.
本考案者は、この目的を達成し得る合成樹脂管
として種々の構造の管を研究し試作し試験した

の物質であつて、粗粒状としたものを合成樹脂材
の廃材をバインダーとして利用して一体的に連結
して帯材の一部を構成させ強度部材として利用す
るようにしたものである。 The inventor researched, prototyped, and tested various synthetic resin pipe structures that could achieve this purpose, but when the structure was designed to have a specified pressure resistance, the amount of synthetic resin material used was noticeably reduced. Although we came to the conclusion that it would be difficult to do so, we continued our research and developed the present invention. That is, the present invention departs from the conventional technical idea of forming pipe walls only with synthetic resin materials, and instead uses coarse particles of materials other than synthetic resin materials as a binder using waste materials from synthetic resin materials. It is designed to be used as a strength member by integrally connecting them to form a part of the band material.

Good too. However, since the inner wall formed into a smooth cylindrical shape has less resistance to fluid, it is mainly used for water supply,
Suitable for use in sewage (drainage) channels.
In addition, in the case of a pipe in which the inner wall has an uneven corrugated structure, when an electric wire or the like is inserted, the electric wire or the like is supported only on the inner circumferential surface of the inner surface protrusion of the uneven corrugation. It has the advantage that there is little frictional resistance between the circumferential surface and the electric wire, etc., making it easier to insert the electric wire, etc. In addition, although the spiral waveform of the outer wall is shown as having a rectangular cross-sectional shape, it is not necessarily limited to such a rectangular cross-sectional shape, and the cross-sectional shape of the spiral waveform may be an arc waveform, a trapezoidal waveform, a V It may also be a spiral waveform such as a letter-shaped waveform.

るに至つたのである。<Effects of the invention> As detailed above in the description of the embodiments and as described in the section on means for solving the problems, the present invention utilizes materials other than synthetic resins that are difficult to melt at high temperatures as a reinforcing material. This method uses coarse granules that are easy to remove, and connects and integrates them using synthetic resin waste material to form a reinforcing band, and this reinforcing band can be used to form the outer tube wall. A continuous reinforcing material is installed inside the spiral waveform as a series of reinforcing materials at the top of the spiral waveform and both side walls following the top, and the outer circumferential surface and the inner wall of the pipe are surrounded by synthetic resin wall material. Since the reinforcing band is placed inside and outside the pipe, it is not exposed inside and outside the pipe, so even if the mixing ratio of coarse particles is increased, it will not become brittle and break, and will last for many years. It is possible to obtain a synthetic resin pipe that is strong against not only external pressure but also internal pressure, and therefore the walls of other synthetic resin materials can be made considerably thinner, reducing the amount of synthetic resin material used and making it cheaper. This has resulted in the remarkable effect of being able to provide the market with synthetic resin spirally corrugated pipes that can withstand years of use.
