RIVER GRAVELとは 意味・読み方・使い方

During the passage of river water through the gravel contact part 7, a pollutant or the like adheres to gravels or is removed by microbial decomposition to clean river water.例文帳に追加

そして河川水が、礫間接触部７を通過する間に、汚染物質等が礫に付着したり微生物分解によって除去されて浄化される。 - 特許庁

Since this cleaned river water flows in the lake from the gravel contact part 7, that is, river water is cleaned immediately before river water flows in the lake, the cleaning effect of the lake is enhanced.例文帳に追加

この浄化された河川水が礫間接触部から湖に流入するので、つまり、河川水が湖に流入する直前で浄化されるので、湖の浄化効果が高くなる。 - 特許庁

An installation part 10 is provided to an inflow part 4 where river water flows in the lake 1 and the installation part 10 is equipped with a plurality of gravels 12 to install a gravel contact part 7 for cleaning river water by passing river water through the gaps among gravels while bringing the same into contact with gravels.例文帳に追加

河川水が湖１に流入する流入部４に、設置部１０を設け、この設置部１０に、複数の礫１２を備え、礫間を河川水が礫に接触しながら通過することによって河川水を浄化する礫間接触部７を設置する。 - 特許庁

A pipe line 3 is disposed on the bottom of a river 2, a gravel layer 4 is disposed on the pipe line 3, a sand layer 5 is disposed on the gravel layer 4, and a biofilm 6 composed of organisms separating pollutants in water is disposed on the surface of the sand layer 5.例文帳に追加

河川２の底部に管路３を配設し、管路３の上部に砂利層４を配設し、砂利層４の上部に砂層５を配設して、砂層５の表面には水中の汚染物質を分離する生物で構成される生物膜６が配設される。 - 特許庁

To establish a function of allowing safe rising operation while assuming uneven load caused by sediment in a pneumatic derricking gate composed of a plurality of unit gates with a large span and installed in a river with much sand and gravel flowing down.例文帳に追加

砂礫の流下の多い河川に設置した径間が大きく、複数の単位ゲートで構成された空圧式起伏ゲートにおいて、堆砂による不均一な載荷を想定しつつ、安全に起立操作が可能な機能を確立する。 - 特許庁
