临朐县大蚕场水库放水洞除险加固措施探讨

Discussion on Risk Elimination and Reinforcement Measures for the Outlet Tunnel of Dacanchang Reservoir in Linqu

摘要:

临朐县小型水库众多,拥有放水洞的小型水库大多数完成封堵工作,但部分未经封堵的小型水库在多年运行后出现放水洞渗水问题。文中以大蚕场水库为例,通过方案比选确定采用内衬钢管加水泥砂浆灌缝充填的加固方案更为合理可行,建设成效显著,可为相关小型水库的放水洞除险加固提供参考借鉴。

Abstract:

There are numerous small reservoirs in Linqu County, and most of those equipped with outlet tunnels have completed plugging construction. However, some unplugged small reservoirs have suffered seepage problems in outlet tunnels after years of operation. Taking Dacanchang Reservoir as an example, this paper determines through scheme comparison that the reinforcement scheme of lining steel pipe combined with cement mortar grouting and filling is more reasonable and feasible, with remarkable construction effects. It can provide a reference for risk elimination and reinforcement of outlet tunnels of similar small reservoirs.
