Cofferdam construction method and cofferdam structure
The invention discloses a cofferdam construction method. The method comprises the following steps of 1) filling an underwater embankment; 2) filling a hole slag inverted filter material on the inner side of a weir body; 3) filling a soil and stone backfill material; 4) diaphragm wall construction; 5) curtain grouting construction; 6) constructing a composite geomembrane; 7) coping and wave wall construction; and 8) slope construction. The inner side face of the embankment is filled with the hole slag inverted filter material, the weir body defined by the embankment is filled with the soil andstone backfill material, a diaphragm wall extending to a covering layer is poured in the middle of the soil and stone backfill material, the composite geomembrane is arranged in the soil and stone backfill material above the diaphragm wall, a coping is poured at the top of the soil and stone backfill material above the composite geomembrane, and a wave wall is arranged on one side of the upstreamface of the coping. According to the method, the stability of the cofferdam and the water retaining performance of the cofferdam are effectively improved, and safer conditions are provided for cofferdam construction.
围堰施工方法，包括以下步骤：1）水下戗堤填筑；2）堰体内侧的洞渣反滤料填筑；3）土石回填料填筑；4）防渗墙施工；5）帷幕灌浆施工；6）复合土工膜施工；7）压顶及挡浪墙施工；8）边坡施工。所述的戗堤内侧面填筑有洞渣反滤料，戗堤所围筑的堰体内填筑有土石回填料，土石回填料的中部浇筑有延伸至覆盖层的防渗墙，防渗墙上方的土石回填料内设有复合土工膜，复合土工膜上方的土石回填料顶部浇筑有压顶，压顶的迎水面一侧上设置有挡浪墙。本申请有效提升了围堰稳固性和围堰的挡水性能，为围堰施工提供更加安全的条件。
