Steel sheet pile cofferdam construction process
The invention discloses a steel sheet pile cofferdam construction process. The steel sheet pile cofferdam construction process comprises the steps of preparation before construction, guide pile driving construction, steel sheet pile inserting and driving construction, steel sheet pile folding construction, inner support installation, seepage-proofing and leakage-stopping treatment and bottom sealing concrete. The steel sheet pile cofferdam construction process has the beneficial effects that the side pressure of a soil body in a cofferdam to steel sheet piles is reduced through the steel sheet pile cofferdam mode, the pile length is properly decreased, and compared with a traditional cofferdam structure, the steel sheet pile consumption is greatly reduced; due to the fact that the steel sheet piles are located on the water side of the cofferdam, overwater driving and pulling are convenient, the construction difficulty of cofferdam engineering is effectively lowered, the cofferdam construction quality is improved, the construction progress is accelerated, and the construction period is shortened; and the steel sheet piles have a good seepage-proofing effect and good anti-scouring performance, compared with a traditional earth-rock cofferdam, the cofferdam upstream face protection and seepage-proofing workload can be greatly reduced, and the steel sheet pile cofferdam structure has better adaptability and feasibility.
本发明公开了一种钢板桩围堰施工工艺，包括施工前准备、导向桩打入施工、钢板桩插打施工、钢板桩合拢施工、安装内支撑、防渗堵漏处理、封底混凝土。本发明的有益效果是：钢板桩围堰的方式减少了堰内土体对钢板桩的侧压力，使桩长适当缩短，与传统的围堰结构相比，钢板桩用量大大减少；由于钢板桩位于围堰临水侧，水上打拔方便，有效降低围堰工程的施工难度，提高围堰施工质量，加快施工进度，缩短施工工期；且钢板桩具有较好的防渗效果及抗冲刷性能，与传统的土石围堰相比，可大大减少围堰迎水面防护及防渗工作量，这种钢板桩围堰结构具有更好的适应性和可行性。
