鲁基厂水电站拦河闸坝建于厚达42m的砂卵砾石覆盖层,由混凝土闸坝和土石坝连接段组成。拦河坝基础及土石坝坝体防渗采用混凝土防渗墙,基岩采用帷幕灌浆。为减少右岸崩坡积体大开挖,右岸坝肩采用了设置灌浆洞进行多次循环灌浆的防渗方式,各防渗体之间的衔接处理是本工程防渗系统设计的重点。工程目前已经全面进入生产运行期,从大坝监测资料分析来看,大坝防渗系统的设计有效,渗流稳定,且明显减小了坝基渗透压力。
The Lujiadian Hydropower Station Barrage is built on a sand-gravel covering of 42m thick and consists of a concrete dam and an earth-rock dam connecting section. Dam foundation dam and dam seepage control concrete cutoff walls, bedrock curtain grouting. In order to reduce the excavation of right bank collapse landslide, the right bank abutment adopts the grouting hole to carry out multi-circulation grouting anti-seepage way, the connection between the seepage control body is the key point of this project anti-seepage system design. The project has now entered full production and operation period. According to dam monitoring data analysis, the design of dam seepage control system is effective and seepage is stable, and the seepage pressure of dam foundation is obviously reduced.
