摘要
对于水库坝下涵管需弃管重建的水利工程,常规的处理方案是破坝重新埋设新管或开挖隧洞.这两种方案存在工程量多、投资大、施工期长和影响蓄水等缺点.为此,在村头坪水库中采用顶管法处理坝下涵管,该方法具有工程量少、投资小、施工期短和不影响蓄水等优点,经过两个汛期运行考验,证明该方法质量可靠,可在中小型水库坝下涵管处理中推广运用.
The conventional method on treating the abandoned culvert under earth dam is the method of burying culverts and digging tunnels.But the methods have the great quantity,the large investment and the long construction period.But the jacking method has the feather of the small quantity,the small investment and the short construction period.It should be applied in the middlesmall reservoirs.
