Concrete core wall rock-fill dam structure body form and construction method
The invention discloses a concrete core wall rock-fill dam structure body and a construction method, and the concrete core wall rock-fill dam structure body comprises a concrete core wall, mortar grouting rock-fill areas are arranged on two sides of the concrete core wall, downstream rock-fill areas are arranged on the downstream sides of the mortar grouting rock-fill areas, upstream rock-fill areas are arranged on the upstream sides of the mortar grouting rock-fill areas, and a curtain is arranged at the foundation of the lower part of the concrete core wall. And a downward grouting hole is further formed in the mortar grouting rock-fill area. The mortar grouting rockfill areas are arranged on the two sides of the concrete core wall, and the concrete core wall and the grouting rockfill areas on the two sides form a cemented whole, so that the rigidity of a downstream supporting body of the concrete core wall is improved, the resistance of the downstream supporting body is improved, the stress and deformation of the concrete core wall are reduced, and safety and reliability of the concrete diaphragm wall and the dam body are guaranteed; the problems that a concrete core wall is complex in stress condition and prone to cracking are solved, the permeation stability and safety of the concrete anti-seepage wall and the dam body are effectively improved, transition areas and inverted filter areas on the two sides of the core wall are omitted, and the partition structure of the core-wall rock-fill dam is simplified.
本发明公开了一种混凝土心墙堆石坝结构体型及施工方法，包括混凝土心墙，混凝土心墙的两侧设置砂浆注浆堆石区，砂浆注浆堆石区下游侧设置下游堆石区，上游侧设置上游堆石区，混凝土心墙下部基础处设置帷幕，砂浆注浆堆石区内还设置有向下的注浆孔。在混凝土心墙两侧设置砂浆注浆堆石区，且混凝土心墙与两侧注浆堆石区形成胶结的整体，提高混凝土心墙下游支撑体的刚度、增加其抗力，减少混凝土心墙应力及变形，保障了混凝土防渗墙和坝体安全可靠，解决了混凝土心墙的受力条件复杂、易产生裂缝的问题，有效的提高了混凝土防渗墙和坝体的渗透稳定安全性，取消了心墙两侧过渡区、反滤区，简化了心墙堆石坝的分区结构。
