德厚水库大跨度输水钢拱管缆索吊装施工

Hoisting Construction Technology of Steel Arch Pipe Cable for Large Span Water Delivery in Dehou Reservoir

德厚水库提水管线跨河拱管所在位置地势较为复杂,两岸为悬崖峭壁且跨河拱管跨度较长,为输水钢拱管,河面至拱管起拱线约60+m,无有利施工便道及机械操作平台,通过采用缆索吊装施工技术,完成了跨河拱管安装,取得了良好的施工效果.

The location of the river crossing arch pipe of the water lifting pipeline of Dehou reservoir is complex,with cliffs on both sides.The arch pipe across the river is water delivery steel arch pipe with a long span.The arch line from the river to the arch pipe is about 60 m.There is no convenient construction access and mechanical operation platform.Through cable hoisting construction technology,the arch pipe across the river has been installed and good construction results have been achieved.
