[0030] <Example 1>
[0031] like Figures 1 to 4 As shown, this embodiment provides a precast sheet pile 10, including first to fourth sides, namely, first side 1, second side 2, third side 3, and fourth side 4. Adjacent sides are perpendicular to each other. The first and third sides are arranged opposite each other, and the second and fourth sides are arranged opposite each other. The first and third sides are used for splicing adjacent precast sheet piles, and the second and fourth sides are used for clamping the precast sheet piles during installation by the pile driver. A cavity 5 is provided in the middle of the precast sheet pile, which can reduce material usage. The first side 1 and the third side 3 are respectively provided with mutually cooperating tenons 11 and tenons 31, so that adjacent tenons and tenons can interlock during splicing of adjacent precast sheet piles, enhancing the stability of the connection. The tenons 11 and tenons 31 extend along the length direction X of the precast sheet pile. In this embodiment, they are the same length as the precast sheet pile, so that the tenons and tenons have a longer length, making the splicing more stable. Those skilled in the art will know that they can also extend at local positions on the first and third sides of the precast sheet pile, and can be varied according to the size and design requirements of the precast sheet pile. In this embodiment, the tenon 11 and tenon 31 can be arc-shaped, allowing for relative translational splicing; alternatively, they can be dovetail-shaped for vertical insertion splicing. The second side surface 2 and the fourth side surface 4 are provided with a plurality of spaced protrusions 21 and grooves 22. The protrusions 21 and grooves 22 extend along the width direction Y of the second and fourth sides, penetrating the first side surface 1 and the third side surface 3. The plurality of protrusions 21 and grooves 22 are spaced along the length X of the precast sheet pile. The concave-convex structure formed on the first and third sides facilitates the clamping of the pile driver, increasing the friction force during clamping; furthermore, it increases the lateral resistance between the sheet pile and the soil, improving its mechanical properties. In the above technical solution, the concave-convex structure formed on the two sides facilitates the clamping of the pile driver; and during installation, it enhances the lateral resistance with the soil, improving its mechanical properties.
[0032] Further, the tenon 11 and the mortise 31 are provided with mutually matched pre-buried engaging members 6, after the tenon 11 and the mortise 31 of adjacent precast piles are spliced, the pre-buried engaging members 6 are matched with each other, the pre-buried engaging members 6 can be steel plates, and are fixedly connected through welding; or can be existing connecting components such as mechanical connecting members.
[0033] Further, the pre-buried engaging members 6 in the mortise 31 are located on both sides of the mortise 31, and the pre-buried engaging members 6 of the tenon 11 are located in the middle part, after assembly, the pre-buried engaging members of the tenon 11 and the mortise 31 are combined together, and support can be formed in the transverse and longitudinal directions, better interlocking effect is obtained, and the connection is more firm.

The convex part 21 or the groove 22 is provided with a through hole 23, facilitating temporary stable clamping of a pile machine.
[0035] As shown in Figures 7 to 9 Further, a convex rib 24 is arranged between adjacent convex parts 21, the convex rib 24 penetrates the groove 22 and is connected to the convex part 21 at both ends, the convex rib 24 is perpendicular to the convex part 21, the convex part 21 enhances the torsional resistance, and the convex rib 24 enhances the bending resistance. The convex part 21 and the convex rib 24 in succession can increase the lateral stiffness of the precast pile and improve the soil retaining effect. A plurality of convex ribs 24 are arranged on the same straight line, the convex rib 24 extends along the length direction of the precast pile, so that the coverage range of the convex rib is increased, and the convex rib 24 is located in the middle part of the groove 22. The through hole 23 is arranged in the groove 22 on both sides of the convex rib 24. A transition surface 25 is arranged between the convex part and the groove, so as to avoid stress being too concentrated between the convex part and the groove, the width of the first side face 1 and the third side face 3 is the same, the width of the second side face 2 and the fourth side face 4 is the same, and the width of the first side face 1 is less than the width of the second side face 2.
