BACKWATER COUNTERMEASURE WATERWAY SYSTEM
To provide a backwater countermeasure waterway system which can surely take countermeasures against backwater and can reduce its construction cost by forming a conduit that generates water flow from a tributary side to a main stream side in order to prevent backwater, and that passes through a confluence point from the tributary side and extends to the main stream side.SOLUTION: The present invention pertains to a backwater countermeasure waterway system that uses a conduit 3 that passes through a confluence point 4 from a tributary stream 2 to a main stream 1 and is disposed within the main stream 1, wherein the conduit 3 has a tributary conduit section 7 arranged in the tributary stream 2 and a main conduit section 8 arranged in the main stream 1, and the tributary conduit section 7 is installed so that the longitudinal direction of the tributary conduit section 7 is configured to be parallel to the water flow of the tributary stream 2, and connected to the main conduit section 8 that passes through the confluence point 4 with the main stream 1 and is installed parallel to the flow of water in the main stream 1.SELECTED DRAWING: Figure 1
【課題】本発明は、バックウォーター対策を行うべく支流側から本流側に向かう水流を発生させる管路を支流側から合流点を通過し、本流側に延出する管路を形成するなどし、もって確実にバックウォーター対策がなしえ、かつその構築コストも安価にそうるバックウォーター対策用水路システムを提供する。【解決手段】本発明は、支流２内から本流１への合流地点４を通過し、前記本流１内に配置される管路３を用いたバックウォーター対策用水路システムであり、前記管路３は、支流２内に配置される支流管路部７と本流１に配置される本流管路部８を有し、支流管路部７は、該支流管路部７の長手方向が支流２の水の流れと平行するよう設置され、かつ本流１との合流地点４を通過し、本流１の水の流れと平行するよう設置された本流管路部８と繋がって構成された管路３を用いたことを特徴とする。【選択図】図１
