Construction method of upstream anti-seepage structure of roller compacted concrete gravity dam
The invention discloses a construction method of an upstream anti-seepage structure of a roller compacted concrete gravity dam, which comprises the following steps: S1, chiseling the upstream face of a dam body, and then grouting and sealing concrete cracks on the upstream face of the dam body; s2, anchor bars are driven into the upstream face of the dam body, then a reinforcing mesh is installed, a formwork is erected, concrete is poured, and an anti-seepage panel is manufactured; the anti-seepage face plate is of an L-shaped structure composed of a main face plate and a front toe, the main face plate is arranged on the upstream face of a dam body in an attached mode, the front toe is arranged on a dam front platform, and a grouting pipe extending downwards is arranged in the front toe. And S3, grouting construction of an anti-seepage curtain is conducted on the dam front platform below the front toe through the grouting pipe. The anti-seepage structure is easy to implement, and the upstream anti-seepage structure of the roller compacted concrete gravity dam obtained through construction of the anti-seepage structure is stable, durable and good in anti-seepage effect.
本发明公开了一种碾压混凝土重力坝上游防渗结构的施工方法，包括如下步骤：S1，对坝体迎水面进行凿毛处理，然后对其上的混凝土裂缝进行灌浆封闭处理；S2，在坝体迎水面上打入锚筋，然后安装钢筋网、立模板，浇筑混凝土制作防渗面板；所述防渗面板为由主面板和前趾构成的L型结构，所述主面板贴附设置在坝体迎水面，所述前趾设置在坝前平台上，且前趾内设置有向下延伸的灌浆管；S3，通过灌浆管向前趾下方的坝前平台灌浆施工防渗帷幕。本发明易于实施，由其施工得到的碾压混凝土重力坝上游防渗结构，稳固持久，防渗效果较好。
