downspout(落水管/雨水管):连接屋顶排水槽(gutter),把雨水从屋檐引到地面或排水系统的竖直管道。英式英语中常见对应说法为 downpipe。除建筑含义外,也可引申指“信息或资源的输入渠道”(较少见)。
/ˈdaʊnspaʊt/
The downspout is clogged with leaves.
落水管被树叶堵住了。
After the storm, water poured from the gutter into the downspout, flooding the walkway where the pipe had come loose.
暴风雨后,雨水从排水槽涌入落水管,因为管子松脱,导致人行道被淹了。
由 down-(向下) + spout(喷口、管口;喷出) 组合而成,字面意思是“向下的出水口/出水管”,形象描述雨水从屋顶被引导向下排出的结构。
