Abstract

The invention discloses a steel sheet pile, a steel sheet pile cofferdam and a construction method of the steel sheet pile cofferdam. The steel sheet pile comprises a steel sheet pile body, and the steel sheet pile body comprises two oppositely-arranged connecting end faces. A male connector is arranged on one of the connecting end faces in a protruding mode. A first connecting block and a secondconnecting block are arranged on the male connector, and the first connecting block and the second connecting block are arranged in a staggered mode. A female joint is convexly arranged on the other connecting end surface. A groove is formed in the end, away from the connecting end face, of the female connector, and a third connecting block and a fourth connecting block are arranged in the groove.The third connecting block and the fourth connecting block are arranged in a staggered manner. The first connecting block and the second connecting block on the male connector and the third connecting block and the fourth connecting block on the female connector are matched and clamped together, a firmer clamping mode is achieved, and in the using process, the male connector and the female connector are not prone to being damaged.

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...
