水源新工程─—河内潜砂井

A New Water Source Project── Sandy Well in River Bed

山东省招远市水利局在吸取群众经验的基础上，经过多年的探索，科学地创造了一项低山丘陵干旱缺水区的水源新工程─—河内潜砂井，即井址在河内，井口封闭且潜伏在河床砂内。论文阐述了河内潜砂井工程的结构类型、特点及效益。河内潜砂井技术上可行且经济合理，产水量高且水质净化好，节省土地且使用年限长，施工简单且管理方便，是一种有推广价值的水源开发新工程。

A new water source project called sandy well in river bed in the hilly and water shortage region is developed by the Water Conservancy Bureau of Zhaoyuan City of Sandong Province based on farmers experience and years study.
