Double-layer steel sheet pile cofferdam and construction method thereof
The invention relates to the technical field of traffic engineering, in particular to a double-layer steel sheet pile cofferdam and a construction method thereof.The cofferdam comprises a plurality of first double-layer steel sheet piles and a plurality of second double-layer steel sheet piles which are connected with each other to form a closed-loop structure; the first double-layer steel plate pile comprises two first steel plates and a first connecting plate, the first steel plates and the second steel plates are arranged in a staggered mode in the length direction, the opening directions are opposite, first lock catches are arranged on the two sides of each first steel plate, and the adjacent first steel plates are connected in an inserted mode through the first lock catches; each second double-layer steel plate pile comprises two second steel plates and a second connecting plate, the sections of the two second steel plates are arc-shaped, second lock catches are arranged on the two sides of each second steel plate, and the adjacent first steel plates and second steel plates are connected in an inserted mode through the first lock catches and the second lock catches to form a double-layer closed-loop structure, so that connection is tighter; the water flow hedging effect during single-side leakage is effectively avoided, the overall stress balance is guaranteed, the bearing capacity of the cofferdam is further improved, and the waterproof and leaking stoppage effects are guaranteed.
本发明涉及交通工程技术领域，尤其涉及一种双层钢板桩围堰及其施工方法，围堰包括：若干第一双层钢板桩和若干第二双层钢板桩相互连接，形成闭环结构；第一双层钢板桩包括两个第一钢板和第一连接板，第一钢板和第二钢板在长度方向上错层设置，且开口方向相反，第一钢板的两侧均设置有第一锁扣，相邻第一钢板通过第一锁扣插接；第二双层钢板桩包括两个第二钢板和第二连接板，两第二钢板截面形状均为弧形，第二钢板的两侧均设置有第二锁扣，相邻的第一钢板和第二钢板通过第一锁扣和第二锁扣插接，形成双层的闭环结构，使得连接更加紧密，有效避免单侧泄漏时的水流对冲作用，保证了整体的受力均衡性，进一步提高围堰的承载能力，保证防水堵漏效果。
