Construction method of steel sheet pile cofferdam deeply covered with sandy gravel layer
The invention relates to a bridge foundation construction technology, and particularly discloses a construction method of a steel sheet pile cofferdam deeply covered with a sandy gravel layer. The construction method comprises the following steps that S1, a construction area of the steel sheet pile cofferdam is determined; S2, a steel casing is inserted and hit, a guide frame bracket is welded, and a guide frame and a limiting clamping plate are connected to the guide frame bracket; S3, inserting and driving construction of the steel sheet piles is conducted through the guide frame; S4, bottom sealing concrete is poured at the bottom of the steel sheet pile cofferdam; S5, a plurality of surrounding purlins and inner supports are arranged in the steel sheet pile cofferdam; S6, secondary bottom sealing is conducted on the bottom of the steel sheet pile cofferdam; S7, after accumulated water in the steel sheet pile cofferdam is pumped through a water suction pump, a bearing platform is poured on the bottom sealing concrete; and S8, after the bearing platform is formed, the steel sheet pile cofferdam is dismantled. The construction method of the steel sheet pile cofferdam deeply covered with the sandy gravel layer is easy to operate, the construction process is safe and reliable, and the construction progress is fast.
本发明涉及桥梁基础施工技术，具体公开了一种深覆盖砂卵石层的钢板桩围堰施工方法，包括如下步骤：S1、确定钢板桩围堰的施工区域；S2、插打钢护筒，焊接导向架牛腿，导向架牛腿上连接有导向架和限位卡板；S3、依托导向架进行钢板桩的插打施工；S4、在钢板桩围堰的底部浇筑封底混凝土；S5、在钢板桩围堰内设置多道围檩和内支撑；S6、对钢板桩围堰的底部进行二次封底；S7、利用抽水泵抽取钢板桩围堰内的积水后，在封底混凝土上浇筑承台；S8、承台成型后，拆除钢板桩围堰。本发明的深覆盖砂卵石层的钢板桩围堰施工方法操作简单，施工过程安全可靠，施工进度快。
