Summary: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 rea
