Novel panel structure of concrete faced rockfill dam and construction method thereof
The invention provides a novel panel structure of a concrete faced rockfill dam and a construction method thereof. The panel structure comprises a reinforced concrete panel, a cushion layer area, a transition layer area, a wave wall and a concrete toe board, wherein an HDPE anti-seepage structure is arranged between the cushion layer area and the reinforced concrete panel; the HDPE anti-seepage structure comprises a plurality of HDPE membrane units which are connected in sequence; every two adjacent HDPE membrane units are connected through an HDPE double-wing concrete connecting lock, and the free ends of the HDPE membrane units which are located on both ends are respectively connected with HDPE single-wing concrete connecting locks; a connecting lock body of the HDPE double-wing concrete connecting lock is poured in the reinforced concrete panel; and a connecting lock body of the HDPE single-wing concrete connecting lock is poured in the corresponding wave wall/concrete toe board. According to the novel panel structure, the HDPE anti-seepage structure is arranged, so that the seepage damage risk caused by failure of the reinforced concrete panel can be obviously reduced.
本申请提供一种面板堆石坝新型面板结构及其施工方法，所述面板结构包括钢筋混凝土面板、垫层区、过渡层区、防浪墙及混凝土趾板，垫层区和钢筋混凝土面板之间设置有HDPE防渗结构；HDPE防渗结构包括若干依次连接的HDPE膜片单元；相邻的两个HDPE膜片单元之间通过HDPE双翼混凝土连接锁相连接，位于两端的HDPE膜片单元的自由端分别与HDPE单翼混凝土连接锁相连接；HDPE双翼混凝土连接锁的连接锁本体浇筑在钢筋混凝土面板内；HDPE单翼混凝土连接锁的连接锁本体浇筑在对应的防浪墙/混凝土趾板内。本申请通过设置HDPE防渗结构，可以显著降低因钢筋混凝土面板失效引起的渗透破坏风险。
