Prestressed concrete corrugated sheet pile and preparation method thereof

The invention relates to a prestressed concrete corrugated sheet pile and a preparation method thereof, and belongs to the technical field of construction engineering. The prestressed concrete corrugated sheet pile solves the problems that an existing corrugated sheet pile is poor in soil blocking and water retaining effect and prone to damage at a corrugated sheet pile joint in the transportationprocess. The prestressed concrete corrugated sheet pile comprises a corrugated pile body, wherein a tenon is arranged on one side in the length direction of the corrugated pile body in a penetratingmode, and a first groove is formed in the other side of the corrugated pile body in a penetrating mode; the cross section of the tenon and the cross section of the first groove are both semicircular;the tenon can be embedded into the first groove and can rotate in the first groove; a second groove is formed in the concave surface of the first groove in the length direction of the corrugated pilebody in a penetrating mode;
