After the lifting tool 3 is inserted into the first groove 11 or the second groove 21, it is connected to the convex sheet pile 1 or the concave sheet pile 2 by a pin (not shown) passing through the first pin hole 4 and the second pin hole 5.

[0028] In this embodiment, as Figure 2 and Figure 3 shown, convex joint portions 12 are respectively provided on both sides of the convex sheet pile 1. The convex joint portion 12 includes a protruding section 121 formed at the lower section of one side of the convex sheet pile 1 and a pre-buried I-beam 122 formed at the upper section of one side of the convex sheet pile 1. One side wing plate of the pre-buried I-beam 122 is located in the convex sheet pile 1, and the other side exposes the convex sheet pile 1 and is flush with the protruding section 121.

By analogy, all the sheet piles that need to be used are connected to each other.

[0036] Of course, in other embodiments, the concrete sheet piles also have other structures, for example, the prefabricated assembled concrete sheet piles include a sheet pile body and a hanger detachable from the sheet pile body, and the two sides of the sheet pile body are respectively provided with a convex part and a concave part. That is, the structure of each sheet pile is the same, with a convex part on one side and a concave part on the other side. During operation, the first sheet pile is inserted first, assuming that the left side of the sheet pile is a concave part and the right side is a convex part, and then the second sheet pile is inserted from the right side of the first sheet pile. The second sheet pile is also a structure of a concave part on the left side and a convex part on the right side. The second sheet pile is inserted from top to bottom on the right side of the first sheet pile, so that the concave part of the second sheet pile is sleeved on the convex part of the first sheet pile, and then the third sheet pile is connected, and so on.
