Description
【発明の詳細な説明】 通信線あるいは電線の保護トラフに関するものである。[Detailed description of the invention] It relates to protective troughs for communication lines or electric lines.
従来、通信線・電線等のケーブルの保護トラフとしてセ

は透水性がある上に、耐衝撃性が弱く、シばしば補修の
必要に迫られていた。Conventionally, cement troughs 7 have been used as protective troughs for cables such as communication lines and electric wires, but cement troughs are permeable to water and have low impact resistance, often requiring repair. It was getting worse.
本発明は上記欠点を除くものであって、火災発生によっ
て送電、通信に障害が起こらないようにしたものである
。The present invention eliminates the above-mentioned drawbacks and prevents power transmission and communication from being disrupted by the occurrence of a fire.
次に本発明を図面に基づいて説明する。Next, the present invention will be explained based on the drawings.

骨材としてはナイロン等の合成繊維、石綿、岩綿、ガラ
ス繊維等の無機繊維あるいは砂、砂利等が使用されるが
、無機繊維が好適である。As the aggregate, synthetic fibers such as nylon, inorganic fibers such as asbestos, rock wool, and glass fibers, or sand, gravel, etc. are used, and inorganic fibers are preferred.
セメントは通常のボルトラントセメントの他にアルミナ
セメント、石膏等が使用され得る。As the cement, alumina cement, gypsum, etc. may be used in addition to ordinary boltant cement.

ク（昭和高分子■製）を使用することができる。If strength is required for the inner layer, use glass fiber mat. A polyester resin reinforced with glass fiber cloth may be used, and a polyester resin reinforced with, for example, Rivolac (trade name, manufactured by Showa Kobunshi ■) can be used.

示すような平坦、な形でもよい。Although the trough lid 2 is shown with seven flange 2a formed around its periphery (FIG. 2), the trough lid 2 may also have a flat shape as shown in FIG. 3.
４はトラフ内に最初に敷設されたケーブルであり、５は
第一次増設時のケーブル、６は第二次増設時のケーブル
を示すものである。Reference numeral 4 indicates a cable initially laid in the trough, 5 indicates a cable at the time of the first expansion, and 6 indicates the cable at the time of the second expansion.
尚この実施例ではトラフに蓋のあるものを記載している
が蓋がなくともよい場合もある。In this embodiment, the trough is described as having a lid, but there may be cases where the trough does not need to have a lid.
本発明は上記の構成でトラフ内面に合成機側が被覆しで
あるので、トラフ内にケーブルを引入れる時に滑シを利
用して円滑に装填できケーブルを傷つける恐れはない。In the present invention, the inner surface of the trough is coated with the synthesizer side, so that when the cable is drawn into the trough, it can be loaded smoothly using the slider, and there is no risk of damaging the cable.
又１従来のセメント製トラフに比べて強度が大であり、
骨材とセメントからなるトラフ外層に水が浸透しても合
成樹脂の内層によ多水分が遮断されるので、ケーブルが
浸水するおそれがなく、防水性能は完全である。Also, it has greater strength than conventional cement troughs,
Even if water penetrates the outer layer of the trough, which is made of aggregate and cement, the inner layer of synthetic resin blocks moisture, so there is no risk of the cable getting wet, and the cable is completely waterproof.
更に、ケーブルが敷設されている地下共同溝内等で火災

態では、こ性がある。Furthermore, even if a fire breaks out in an underground common ditch where cables are laid, the situation will be the same as if the lid 2 was installed, for example, a fireproof ceiling, even if it is not installed. This problem occurs when the opening side of the trough is in contact with the side wall and fixed with a support fitting.
又、トラフが本体と蓋とからなる場合には中空管の場合

とができるのでケーブル増設、交換時の作業が容易にで
きる。Furthermore, when the trough consists of a main body and a lid, unlike the case of a hollow tube, the lid can be removed at will to open the trough, making it easier to add or replace cables.
