A method for installing an anchor assembly for a prefabricated wind power generation foundation, which is applied to the anchor assembly for a prefabricated wind power generation foundation described in claims 1 to 8, characterized in that: The following steps are involved: S1, multiple plastic sleeves 1 (7) are arranged at equal intervals in the casting mold of the upper foundation ring so as to be cast together with the upper foundation ring, multiple plastic sleeves 2 (11) are arranged at equal intervals in the casting mold of the lower foundation segment, and two lower anchor plates (9) are arranged at both ends of the plastic sleeves 2 (11) so as to be cast together with the lower foundation segment; S2. Each support screw rod (1701) is arranged in a circular shape at equal intervals on the positioning holes of the positioning ring (16). A washer three (1703) is sleeved on the lower end of the support screw rod (1701) and connected to a hexagonal nut three (1702). Another hexagonal nut three (1702) is connected to the upper part of the support screw rod (1701). The two hexagonal nuts three (1702) fix the positioning ring (16), and the embedded plate (1704) is embedded in the foundation cushion layer. S3, the pins (1501) are distributed in the positioning holes of the positioning ring (16) at equal intervals, a washer four (1503) is sleeved on the lower end of the pin (1501) and connected to a hexagonal nut four (1502), and another hexagonal nut four (1502) is connected to the upper end, so that the two hexagonal nuts four (1502) are in contact with the positioning ring (16); S4, an anchor hole at the bottom of the lower foundation segment is sleeved on the pin (1501), and the lower foundation segment is fitted with the positioning ring (16). After all the lower foundation segments are assembled, the positioning pin 2 (15) is removed from the positioning ring (16); S5. Sleeve a rubber gasket (8) on the upper end of the second plastic sleeve (11), and insert the first positioning pin (10) into the large concave hole reserved in the lower base segment; S6. Connect the small concave hole at the bottom of the upper foundation ring to the corresponding positioning pin 1 (10), so that the upper foundation ring is placed on the lower foundation segment; S7, the anchor rod (2) in the positioning anchor bolt is passed through the plastic sleeve 1 (7), the rubber washer (8), and the lower plastic sleeve 2 (11) in sequence, the lower end of the anchor rod (2) is connected to the washer 2 (12) and the hexagonal nut 2 (13) in sequence, and the upper end of the anchor rod (2) is connected to the positioning hexagonal nylon nut (5); S8, pass the anchor bolt hole of the upper anchor plate (18) through the anchor rod (2) and place it on the positioning hexagonal nylon nut (5), so that the upper anchor plate (18) is set at the water level, and the upper end of the anchor rod (2) is then connected with a washer (4) and a hexagonal nut (3) in sequence; S9. The anchor rod (2) of the common anchor bolt is passed through the upper anchor plate (18), the sealing plug (6), the plastic sleeve 1 (7), the rubber washer (8), and the plastic sleeve 2 (11) in sequence. The lower end of the anchor rod (2) is connected to the washer 2 (12) and the hexagonal nut 2 (13) in sequence. The upper end of the anchor rod (2) is connected to the washer 1 (4) and the hexagonal nut 1 (3) in sequence.
