The plastic steel sheet pile 1 includes a sheet pile base 101 and protruding edges 102 and concave edges 104 on both sides of the sheet pile base 101. Two sheet pile bases 104 are connected to both sides of the precast concrete pile 2. 1. The connecting sleeves 401 and connecting blocks 402 on both sides of the precast concrete pile 2 are respectively connected to the protruding edge 102 and the concave edge 104 on a sheet pile base 101; when assembling adjacent plastic steel sheet piles 1, the protruding edge 102 on one sheet pile base 101 can be engaged with the concave edge 104 on another sheet pile base 101; the cross section of the protruding edge 102 is circular, and the interior of the concave edge 104 is provided with a groove with a circular cross section, which increases the stress area and makes the connection more secure.
[0023] As a technical optimization of this utility model, the connecting sleeve 401 and the concave edge 104 have the same shape, the convex edge 102 and the connecting block 402 have the same shape, and multiple hollow guide sleeves 403 are equidistantly arranged inside the precast concrete pile 2. The guide sleeves 403 are perpendicular to the through grooves 3 on the precast concrete pile 2. Multiple tie rods 404 are fixed on the connecting sleeve 401, and the tie rods 404 pass through the guide sleeves 403. The guide sleeves 403 and the precast concrete pile 2 are integrally cast and formed. When the guide sleeves 403 and the precast concrete pile 2 are connected... After molding, other components can be installed as needed. The tie rod 404 passes through the guide sleeve 403, so that the connecting sleeve 401 abuts against the precast concrete pile 2. The connecting block 402 is installed on the other side, so that the connecting block 402 engages with the tie rod 404. The tie rod 404 engages with the connecting block 402. The end of the tie rod 404 is threadedly connected to a nut 405, which abuts against the connecting block 402. Rotate the nut 405 so that it abuts against the connecting block 402. The connecting block 402 and the connecting sleeve 401 abut against both sides of the precast concrete pile 2.
[0024] As a technical optimization of this utility model, the docking block 402 is provided with a plurality of waist-shaped grooves 406, and the nut 405 is located in the waist-shaped grooves 406; thus reducing the space occupied.
[0025] As a technical optimization of this utility model, the bottom end of the precast concrete pile 2 is fixed with a edging 5, which is V-shaped, so that the end of the precast concrete pile 2 is inclined, making it easier for the precast concrete pile 2 to be inserted into the soil.
[0026] As a technical optimization of this utility model, the sheet pile foundation 101 is provided with multiple reinforcing ribs 103, and the reinforcing ribs 103 are in the form of semi-cylindrical structures.
[0027] In use, the guide sleeve 403 and the precast concrete pile 2 are integrally cast. After the guide sleeve 403 and the precast concrete pile 2 are formed, other components can be installed as needed.

The connecting block 402 is installed on the other side, so that the connecting block 402 engages with the tie rod 404. Then, the nut 405 is rotated so that the nut 405 abuts against the connecting block 402. The connecting block 402 and the connecting sleeve 401 abut against both sides of the precast concrete pile 2. The nut 405 is located in the waist-shaped groove 406, which reduces the space occupied. Alternatively, the connecting block 402 can be directly welded to the tie rod 404. Then, a pile driver is used to insert the plastic steel sheet pile 1 and the precast concrete pile 2 into the soil. In the soil, when assembling adjacent plastic steel sheet piles 1, the protruding edge 102 on one sheet pile base 101 is engaged with the concave edge 104 on another sheet pile base 101. When connecting plastic steel sheet piles 1 and precast concrete piles 2, the connecting sleeve 401 on the precast concrete pile 2 is connected to the protruding edge 102 on one side of the sheet pile base 101, and the connecting block 402 on the precast concrete pile 2 is connected to the concave edge 104 on another sheet pile base 101. This makes the connection between the sheet pile base 101 and the precast concrete pile 2 more secure, and facilitates the alternating use of plastic steel sheet piles 1 and precast concrete piles 2. The cross-section of the protruding edge 102 is circular, and the interior of the concave edge 104 has a groove with a circular cross-section, which increases the stress area and makes the connection more secure.
