Steel sheet pile island-building cofferdam and construction method
The invention relates to a steel sheet pile island-building cofferdam and a construction method. The construction method comprises the following steps: constructing a steel platform; constructing a steel sheet pile cofferdam; constructing an island and a cofferdam for filling; constructing an internal cofferdam; and bearing platform construction. The method has the beneficial effects that the steel sheet pile positioning support is adopted to conduct auxiliary guide construction on the Larsen steel sheet pile, the outer side positioning steel plate and the inner side positioning steel plate are positioned and adjusted through the position adjusting grooves and the fixing bolts, the Larsen steel sheet pile is driven between the outer side positioning steel plate and the inner side positioning steel plate, and the construction accuracy and the construction efficiency of the steel sheet pile are improved; the steel support hanging plate structure is adopted for steel support installation between the outer side steel sheet pile and the inner side steel sheet pile, the upper hanging plate and the upper anchor tooth plate are arranged on the upper portion of the steel support hanging plate and hung on the steel enclosing purlin stopping block, and the steel support installation construction efficiency is improved.
本发明涉及一种钢板桩筑岛围堰及施工方法，包括以下步骤：钢平台施工；钢板桩围堰施工；筑岛围堰填筑；内部围堰施工；承台施工。本发明的有益效果是：采用钢板桩定位支架对拉森钢板桩辅助导向施工，外侧定位钢板和内侧定位钢板通过位置调整槽和固定螺栓进行定位调整，拉森钢板桩从外侧定位钢板和内侧定位钢板之间打设，提高钢板桩施工精准度和施工效率；采用钢支撑挂板结构进行外侧钢板桩和内侧钢板桩之间的钢支撑安装，钢支撑挂板上部设置上挂板和上锚齿板挂置于钢围檩止方，提高钢支撑安装施工效率。
