Long and narrow deep foundation pit construction cofferdam structure and use method thereof
The invention discloses a long and narrow deep foundation pit construction cofferdam structure in the technical field of construction cofferdams. The long and narrow deep foundation pit construction cofferdam structure comprises a cofferdam main body; the cofferdam main body is formed by connecting multiple S-like steel plate piles with each other in sequence; walings are arranged at the middle parts of the long edges of the internal side of the cofferdam main body; first supporting columns are arranged between the left and right opposite walings; and diagonal bracings are arranged between theend parts of the first supporting columns and the walings. According to the long and narrow deep foundation pit construction cofferdam structure, the designed S-like steel plate piles have higher occlusive waterproof effects during using; and moreover, the steel plate piles can rotate for a large angle without affecting the occlusive waterproof effects; in actual application, the steel plate piles are more actual and reasonable; in particular at the corners of the cofferdam, the steel plate piles can still keep very good waterproof effects without being provided with additional waterproof structural designs; and compared with an existing steel plate pile cofferdam design, the designs of the S-like steel plate piles and a cofferdam method thereof have the advantages that the use is more convenient and the waterproof effect is better.
本发明公开了施工围堰技术领域的一种狭长深基坑施工围堰结构，该围堰结构包括有围堰主体，所述围堰主体由多个类S型钢板桩依次连接而成，所述围堰主体的内侧长边中部设置有围囹，左右相对的围囹之间设有第一支撑柱，所述第一支撑柱的端部与围囹之间设有斜撑，本发明设计的类S型钢板桩在使用时，具有更高的咬合防水效果，且该种钢板桩之间能够大角度旋转而不影响咬合防水效果，在实际应用时更实际合理，尤其在围堰拐角处，其不需要设置另外的防水结构设计，仍能保持很好的防水效果，本方案中类S型钢板桩及其围堰方法的设计相比于现有钢板桩的围堰设计，使用更方便，防水效果更佳。
