The underground multi-purpose duct consists of a cured article comprised of a formulation containing at least cement, pozzolanic fine powders, fine aggregates having a particle size of 2 mm or less, water-reducing admixtures, and water.例文帳に追加

少なくとも、セメント、ポゾラン質微粉末、粒径2mm以下の細骨材、減水剤、及び水を含む配合物の硬化体からなる共同溝。 - 特許庁

To provide a synthetic segment capable of smoothly executing the inner periphery of a tunnel in particular and utilized as a tunnel lining material for an underground multi-purpose duct, a sewerage trunk line, an underground river or the like.例文帳に追加

特にトンネルの内周面を平滑に施工でき、共同溝や下水道幹線、さらには地下河川などのトンネル覆工材として利用される合成セグメントを提供する。 - 特許庁

Preferably, the formulation further contains metallic fibers and/or organic fibers, inorganic powders having an average particle size of 3-20 μm, fibrous particles having an average particle size of 1 mm or less or flaky particles, since these can enhance the flexural strength, fracture strength, denseness, toughness and the like of the cured article, improving the durability of the underground multi-purpose duct.例文帳に追加

さらに、配合物に金属繊維及び／又は有機質繊維、平均粒径3〜20μｍの無機粉末、平均粒度1mm以下の繊維状粒子又は薄片状粒子を含むことは、硬化体の曲げ強度や破壊強度、緻密性や靱性等を高めて共同溝の耐久性等を向上することができるので好ましい。 - 特許庁
