安溪县现有水库89座,其中中型水库2座,小(1)型水库16座,小(2)型水库71座,垅头水库是该县较严重的病险水库之一。文章基于垅头水库大坝防渗加固中存在的问题,进行了深入的分析,针对两种防渗加固方案,从经济性、施工难度和施工工艺、质量方面进行探讨,推荐采用方案(2)——全坝段高压单管旋喷桩防渗结合岩基帷幕灌浆防渗技术,为类似工程提供参照。
There are 89 reservoirs in Anxi County, including 2 medium-sized reservoirs, 16 small reservoirs (1) and 71 small reservoirs (2), which is one of the more serious reservoirs in the county. Based on the problems existing in the seepage prevention and consolidation of Damou Reservoir, the paper analyzes in depth the two schemes of seepage control and reinforcement, and discusses the economic, construction difficulty and construction technology and quality, and recommends scheme (2) - Full dam high pressure single tube grouting pile seepage prevention combined with rock foundation curtain grouting anti-seepage technology, provide a reference for similar projects.
