Anti-seepage grouting construction method for pebble cofferdam
The invention discloses an anti-seepage grouting construction method for a pebble cofferdam, which comprises the following steps of: drilling a hole at an anti-seepage line of the cofferdam, embedding a grouting pipe to form a grouting hole, simultaneously mixing high-concentration paste slurry, and continuously pouring the high-concentration paste slurry into the cofferdam through the grouting pipe by using a high-pressure grouting pump to form an anti-seepage wall body so as to achieve the anti-seepage effect of the cofferdam. The high-pressure grouting pump is used for continuously grouting high-concentration paste slurry into the cofferdam to form an anti-seepage wall, so that the problems of slurry loss, poor applicability and non-ideal anti-seepage effect of the high-pressure jet grouting piles in the pebble cofferdam are solved; and meanwhile, the problems of underground mixing solidification, difficult quality control and difficult anti-seepage effect guarantee of slurry of double-liquid grouting are solved, and the method has the advantages of high efficiency, environmental protection and controllable construction quality.
本发明公开了一种卵石围堰防渗灌浆施工方法，包括在围堰防渗线位置钻孔并埋设灌浆管形成灌浆孔，同时拌制高浓度膏浆，通过高压灌浆泵将高浓度膏浆通过灌浆管连续灌入围堰内，形成防渗墙体，以达到围堰防渗作用。本发明利用高压灌浆泵将高浓度膏浆连续灌入围堰，形成防渗墙，避免了高压旋喷桩在卵石围堰中浆液流失，适用性差，防渗效果不理想的问题；同时也改善双液灌浆的浆液在地下混合凝固，质量控制难，防渗效果不易保证的问题，具有功效高，环保，施工质量可控的优点。
