Construction method of double-wall steel sleeve box cofferdam of pebble riverbed
The invention provides a construction method of a double-wall steel cover box cofferdam of a pebble riverbed, which comprises the following steps: S1, setting a soil taking area and a slope gradient according to the position of a bearing platform, pre-excavating an underwater foundation pit according to the set soil taking area, and trimming the side slope and the base of the underwater foundation pit; s2, the double-wall steel sleeve box cofferdam is integrally lowered to the position above the underwater foundation pit so that the double-wall steel sleeve box cofferdam can float automatically; s3, an anchorage system is installed on the double-wall steel sleeve box cofferdam; s4, the double-wall steel cover box cofferdam rapidly sinks, and implantation is performed after fine positioning; s5, pile casing inserting and driving are conducted in the double-wall steel sleeve box cofferdam; and S6, bottom sealing construction is conducted in the double-wall steel sleeve box cofferdam. The method has the characteristics of high construction speed, safety and stability.
本发明提供一种卵石河床的双壁钢套箱围堰施工方法，包括：S1、根据承台位置设定取土区域和放坡坡度，根据设定的取土区域进行水下基坑预开挖，并修整所述水下基坑的边坡和基底；S2、整体下放双壁钢套箱围堰至所述水下基坑的上方使其自浮；S3、在所述双壁钢套箱围堰上安装锚碇系统；S4、使所述双壁钢套箱围堰快速下沉，精定位后着床；S5、在所述双壁钢套箱围堰的内部进行护筒插打；S6、在所述双壁钢套箱围堰的内部进行封底施工。本发明具有施工速度快，安全稳定的特点。
