Earth and rockfill dam cofferdam anti-seepage system and construction method thereof
The invention relates to the field of waterproof construction, in particular to an earth and rockfill dam cofferdam anti-seepage system and a construction method thereof.The earth and rockfill dam cofferdam anti-seepage system comprises a clay core wall used for preventing seepage of a dam body; the plastic concrete anti-seepage wall is arranged between the clay core wall and the curtain grouting anti-seepage wall and is used for preventing seepage of the dam body and the bed rock; and the curtain grouting prevention wall is arranged at the lower end of the plastic concrete anti-seepage wall and used for preventing seepage of the deep bedrock. The clay core wall is arranged in the dam body in a conical shape. The plastic concrete diaphragm wall is fixed in the earth and rockfill dam and the bed rock through the anchoring structure. And the curtain grouting prevention wall is arranged in the permeable bedrock in a curtain shape. The construction method of the cofferdam anti-seepage system of the earth and rockfill dam comprises the following steps that construction machinery is prepared, a construction platform is built, and pilot holes are drilled; pre-grouting operation is carried out according to geological condition requirements; the plastic concrete diaphragm wall is constructed; grouting a water-permeable bedrock curtain; and the slope rolling device is driven in a reciprocating mode to conduct filling and rolling on the clay core wall.
本发明涉及防水施工领域，更具体的说是一种土石坝围堰防渗体系及其施工方法，一种土石坝围堰防渗体系包括：黏土芯墙，用于对坝体防渗；塑性混凝土防渗墙，设置在黏土芯墙和帷幕灌浆防墙之间，用于对坝体和基岩的防渗；帷幕灌浆防墙，设置在塑性混凝土防渗墙下端，用于对深度基岩防渗。所述的黏土芯墙呈锥形状设置在坝体内。所述的塑性混凝土防渗墙通过锚固结构固定在土石坝和基岩内。所述的帷幕灌浆防墙呈帷幕状设置在透水基岩内。土石坝围堰防渗体系施工方法，包括以下步骤：施工机械准备，修筑施工平台，打设先导孔；根据地质情况需求，实施预灌浆作业；塑性混凝土防渗墙施工；透水基岩帷幕灌浆；通过往复驱动坡度碾压器在黏土芯墙上进行填筑和碾压。
