Construction method for steel sheet pile cofferdam in high-flow-speed sandy gravel area
The invention relates to a bridge bearing platform foundation construction technology, and particularly discloses a construction method for a steel sheet pile cofferdam in a high-flow-speed sandy gravel area. The construction method comprises the following steps that S1, a guide frame is positioned; S2, a streaming protection pile is inserted and driven; S3, steel sheet piles for positioning are inserted and driven; S4, a steel sheet pile cofferdam positioning guide frame is installed through a drilling platform; S5, other steel sheet piles are inserted and driven; S6, closing the steel sheet pile cofferdam; S7, enclosing purlins and inner supports are mounted; S8, bottom sealing concrete is poured; S9, a steel sheet pile cofferdam foundation pit is excavated; and S10, the steel sheet pile cofferdam is dismantled. The construction method for the steel sheet pile cofferdam in the high-flow-speed sandy gravel area is easy to operate, the construction process is safe and reliable, and the construction cost is low.
本发明涉及桥梁承台基础施工技术，具体公开了一种大流速砂卵石区域的钢板桩围堰施工方法，包括如下步骤：S1、导向架定位；S2、插打绕流防护桩；S3、插打用于定位的钢板桩；S4、利用钻孔平台安装钢板桩围堰定位导向架；S5、插打其他钢板桩；S6、钢板桩围堰合拢；S7、安装围檩和内支撑；S8、浇筑封底混凝土；S9、挖掘钢板桩围堰基坑；S10、钢板桩围堰拆除。本发明的大流速砂卵石区域的钢板桩围堰施工方法操作简单，施工过程安全可靠，施工费用低。
