Description
【発明の詳細な説明】 通信線あるいは電線の保護管路に関するものである。[Detailed description of the invention] It relates to protection conduits for communication lines or electric wires.

れらは透水性があり、又、耐衝撃性が弱く、シばしば補
修の必要に迫られていた。Conventionally, conduits made of cement or concrete have been used to protect cables such as communication lines and electric wires, but these are permeable to water, have low impact resistance, and are often It was in need of repairs.
本発明は上記欠点を除くものであって、火災発生によっ

それがなく、防水性能は完全である。In addition, it is much stronger than conventional 7-ment pipes, and even if water penetrates the outer layer of asbestos cement, the inner layer of fiber-reinforced synthetic resin blocks moisture, so there is no risk of the cable being flooded with water. Waterproof performance is complete.
更にケーブルが敷設されている地下共同溝内等で火災が
