Grouting rubble gravity dam heightening and expanding anti-seepage system and construction method
The invention relates to the technical field of water conservancy facilities, in particular to a masonry gravity dam heightening and expanding anti-seepage system and a construction method. The system comprises a new dam body built on the downstream face and the dam top of an old dam body, a curtain grouting part reinforced below a dam foundation of the old dam body and a filling grouting part arranged in the old dam body, the filling grouting part is arranged along the axis of the old dam body and extends to the position below the dam foundation of the old dam body, and a concrete anti-seepage wall is arranged in the new dam body located on the dam top of the old dam body. The new dam body and the old dam body are connected through expansive concrete. The dam body can be effectively heightened, extended and reinforced, the structural strength and the anti-seepage performance of the dam body are enhanced, and the safety problems of scattered immersion and seepage of the dam body are efficiently solved.
本发明涉及水利设施技术领域，具体涉及一种浆砌石重力坝加高扩建防渗系统及施工方法。系统包括砌设于老坝体背水面和坝顶的新坝体，补强于老坝体坝基下的帷幕灌浆部，以及设置于老坝体内的充填灌浆部，所述充填灌浆部沿老坝体的轴线设置，并延伸至老坝体坝基下，位于老坝体坝顶的新坝体内设有混凝土防渗墙，所述新坝体与老坝体之间通过膨胀混凝土连接。本发明可以对坝体形成有效的加高扩建补强，增强坝体的结构强度和防渗性能，高效解决坝体的散浸、渗漏安全问题。
