【考案の詳細な説明】
この考案は地中に配設されるケーブルを薬品、
水及び白蟻等の害から保護するようなケーブルを
格納するためのパイプに関する。[Detailed explanation of the invention] This invention uses chemicals to treat cables installed underground.
This invention relates to pipes for storing cables that are protected from water and termite damage.
地中埋設ケーブルは周囲の環境により、薬品溶

してケーブルの絶縁性能に障害を起すことが知ら
れている。 Depending on the surrounding environment, underground cables may suffer insulation deterioration due to chemical or water trees if they come into contact with chemical solutions or water such as groundwater, or may be susceptible to damage from termites living in the soil. It is known that this can cause damage to the insulation performance of cables.
このため、従来は耐薬品性に強いシースを選択
したり、耐水性の良い遮水層を設けたり、或いは
特に防蟻剤を混入したシースを設けたりしてそれ
ぞれの目的に応じたケーブル構造を設計していた
のが通例で、一つの構造で多目的の効果をあげる
ものは無く、無理にこのようなものを設計し製造
するとコスト高になることは避けられなかつた。 For this reason, in the past, cable structures were designed to suit each purpose by selecting a sheath with strong chemical resistance, providing a water-repellent layer with good water resistance, or providing a sheath mixed with a termiticide. Usually, there was no single structure that could achieve multiple effects, and if such a thing was forced to be designed and manufactured, it was inevitable that the cost would increase.
この考案は上述のような事情に鑑みてなされた
もので、第１図に示すようにポリエステル、エポ

プ３中にケーブル４を収納するものである。 This idea was made in view of the above-mentioned circumstances, and as shown in Figure 1, a reinforced plastic layer 1 made of polyester, epoxy polycarbonate, etc.
This is a cable storage pipe 3 in which a metal foil barrier layer 2 of copper, aluminum, lead, etc. is installed in the middle of (so-called FRP), and a cable 4 is stored in this storage pipe 3 as shown in Fig. 2. It is.

層これらの特性に優れたケーブル格納パイプを提
供することができる。 The plastics applicable here include thermosetting resins such as polyester, polyvinyl ester, unsaturated acrylate, and epoxy-phenol resins combined with a suitable hardener, and mixtures of these with fibers such as glass fiber, carbon fiber, glass flakes, and woven fiber fabrics are known as reinforced plastics, or FRP. Therefore, even if this material itself is made into a pipe shape, it has excellent water resistance, chemical resistance, and termite resistance, making it suitable for storing cables, but as mentioned above, this device has a metal foil barrier layer 2 provided between the reinforced plastic layer 1, so that it can completely block water, chemicals, gases, etc. that pass through the plastic, and can provide a cable storage pipe with even better properties.
ここに金属箔遮断層２を設ける場合はあらかじ

その外側に縦添え又はラツプ巻し、重なり部分を

外部に強化プラスチツク層１の外部側を製作すれ
ばよい。 When providing the metal foil barrier layer 2 here, the inner side of the reinforced plastic layer 1 is prepared in advance,
The outer side of the reinforcing plastic layer 1 can be fabricated on the outside by longitudinally wrapping or wrapping it, and by gluing or welding the overlapping parts to form a complete tubular layer.

ある。 Since the containment pipe of the present invention is mainly composed of the reinforced plastic layer 1, it is mechanically strong and can protect the cable from unexpected cave-ins, impacts, etc., and achieve safe power transmission. In addition, it mechanically protects the metal foil barrier layer 2 provided inside, improves its water-shielding and chemical-shielding properties, and has the advantage of being even more effective in preventing feeding damage by creatures such as rats and termites. There is.
又、この考案の格納パイプは構造が簡単である

ることができる。 In addition, since the storage pipe of this invention has a simple structure, it is easy to manufacture and the cost is low.
The linear expansion coefficient of reinforced plastic and metal foil is (2~
5) Since the ratio is approximately equal to x10 -5 , there is no problem with thermal motion, and since the metal foil barrier layer is not as large as a metal pipe, it is light in weight. For example, if the cable 4 is stored in the storage pipe 3 obtained according to the present invention, excellent effects such as the omission of the cable trough can be achieved.
