坝内排水管
drains in concrete or masonry dam
ba’ne一Palshuiguan坝内排水管、drains一n eonerete ormasonry dam)排除棍凝土或其它污工坝坝体内部渗水的孔管。用以降低坝体浸润线位置，减少坝体扬压力。 坝体排水管通常做成铅直的或接近铅直的，位于上游侧防渗混凝土层之后，与上游坝面的距离一般不小于坝前水深的1/10一1/12。其上端通到坝顶(或溢流堰面以下)，下端通到纵向排水检查廊道或基础排水廊道。通过廊道排水沟或集水井再将渗水排向下游(见图)。排水管卜水管之间剖面的浸润线 一排水管剖面l泊勺浸润线横向廊道 横向廊道内的排水沟即炸教 道 廊 向 纵排水管布置示意图 坝内排水管间距通常为2一3米，内径一般为15一25厘米。常用预制多孔混凝土管，在浇筑混凝土时埋入坝内;有时也用立模法或拔管法在坝内做成排水孔;运行中增设的坝体排水，则为通向廊道的机钻孔。排水孔管在廊道的出露处常加设一段铸铁管，以便集引漏水进行渗漏量观测。 为了排除从横缝中漏入坝体的渗水，有的坝在横缝止水设施的后面也设置排水孔管。必要时还设置排水井兼作检查井。(李珍照)
