[0012] S1, determine the placement position of the prefabricated base, dig a limiting groove for matching the lower end of the prefabricated base at the placement position according to the site slope, hoist the prefabricated base with the built-in adjustment steel column into the limiting groove, and connect and fix the adjacent prefabricated bases with the channel steel beam;

[0013] S2, adjusting the adjusting steel column according to the required height, and using rough flat anchor bolts to sequentially penetrate the rough flat screw holes of the short column and the rough flat screw holes of the steel column to achieve rough flatness;

[0014] S3, adjusting the fine-leveling nut threadedly connected to the fine-leveling bolt according to the required height to move the adjusting steel plate to the required position, then cutting off the fine-leveling bolt above the upper surface of the adjusting steel plate, and welding the adjusting steel plate to the bolt;
