Abstract

The invention discloses a steel sheet pile, a steel sheet pile cofferdam and a construction method for a steel sheet pile cofferdam; the steel sheet pile includes: a steel sheet pile body, the steel sheet pile body includes two oppositely arranged connection end faces; a male joint, the The male connector is protrudingly arranged on one of the connection end faces; a first connection block and a second connection block are arranged on the male connector, and the first connection block and the second connection block are misplaced; the female connector, the female connector The joint is protruded on the other connecting end face; the female joint is formed with a groove at the end away from the connecting end face, and a third connecting block and a fourth connecting block are arranged in the groove; the third connecting block The block and the fourth connection block are misplaced; the first connection block and the second connection block on the male joint cooperate with the third connection block and the fourth connection block on the female joint. Together, a more robust clamping connection is achieved, and the male connector and the female connector are not easily damaged during use.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a steel sheet pile, a steel sheet pile cofferdam and a construction method for the steel sheet pile cofferdam. Background technique [0002] Traditional steel sheet piles form a cofferdam by connecting multiple steel sheet piles together, and set internal supports within the multiple steel sheet piles to strengthen the stability of the cofferdam. [0003] In traditional steel sheet piles, a bending groove is provided at the joint of the steel sheet pile, and a bending protrusion is provided on the corresponding other steel sheet pile. By clamping the bending protrusion in the bending groove, the gap between the two steel sheet piles is A sealed connection is formed to achieve the effect of water stop; however, the bending groove is easily deformed by force during use, resulting in gaps at the joints of the steel sheet piles, which affects the practicabilit...
