防渗墙结合帷幕灌浆在水库防渗中的应用

Application of cut-off wall combining with curtain grouting in seepage prevention project of reservoir

塑性混凝土是用黏土和膨润土取代普通混凝土中的大部分水泥形成的一种柔性工程材料。与普通混凝土相比,塑性混凝土弹性模量低、极限应变大、能适应较大变形、抗渗性能好,同时还具有节约水泥、降低造价等优点。文中结合栗树埂水库除险加固工程实践,对塑性混凝土防渗墙结合帷幕灌浆防渗系统设计、施工和质量检测进行介绍。

The plastic concrete is a kind of flexible engineering material with clay and betonite instead of most of cement in ordinary concrete. Compared with the ordinary concrete, the plastic concrete has advantages of lower elastic modulus, larger ultimate strain and better anti-seepage and deformation resistance, and at the same time has advantages of saving cement and decreasing cost, and so on. Combing with the danger control and reinforcement project practice of Lishugeng reservoir, the paper introduces the design, construction and quality detection of seepage prevention system of the plastic concrete cut-off wall combining with the curtain grouting.
