Steel plate pile and earth dam combined cofferdam and cofferdam construction method
The invention relates to the technical field of bridge engineering construction and provides a steel plate pile and earth dam combined cofferdam which comprises an inner-layer steel plate pile, an outer-layer steel plate pile, and an earth dam filling area defined by the inner-layer steel plate pile and the outer-layer steel plate pile. According to the steel plate pile and earth dam combined cofferdam, the step-slope and the occupied river channel width of the earth dam cofferdam can be limited, the cofferdam construction operating range can be controlled, the water blocking area of the cofferdam is reduced, the impervious capacity is improved, and the overall stability of the cofferdam is high.
本发明涉及桥梁工程施工技术领域，提供一种钢板桩与土坝组合围堰，包括内层钢板桩、外层钢板桩、以及内层钢板桩与外层钢板桩围合形成的土坝填充区域。其能够限制土坝围堰放坡与占用河道宽度，控制围堰施工作业范围，减小围堰阻水面积、提高抗渗能力、围堰整体稳定性强。
