in the step S08, after the steel structure column (4) is installed, after passing inspection, secondary concrete pouring of the cup opening (3) is carried out, the secondary concrete pouring of the cup opening (3) adopts expansion concrete pouring, watering is carried out in advance before pouring the concrete of the cup opening, and the concrete pouring is fully vibrated and compacted.
9. The rapid installation and precise adjustment method for the cup-type foundation steel structure column according to claim 8, wherein the rapid installation and precise adjustment method is characterized by comprising the following steps: in the step S01, the maintenance time is not less than 7 days; in the step S02, roughening is carried out after the concrete strength reaches 1.2MP, the roughening depth is 1-2cm, and the post feet are washed clean after roughening the contact surface of the concrete post; in the step S04, the exposed thread part of the embedded adjusting bolt (5) is protected by winding a transparent adhesive tape; in the step S05, in order to prevent the cup opening template at the inner side of the short column from floating upwards when concrete is poured, screws are respectively fixed on four sides of the cup opening, and a fixed steel pipe is installed through a butterfly buckle; in the step S06, the curing time is not less than 7 days; in the step S07, after the basic strength of the short column (2) reaches 75% of the design strength, the steel structure column (4) is hoisted in the square direction; in the step S08, the concrete grade is improved by one step compared with the concrete grade of the short column (2), and the secondary poured concrete is 0.5cm more than the designed elevation, so that shrinkage cracking is prevented when the concrete is solidified.
10. The rapid installation and precise adjustment method for the cup-type foundation steel structure column according to claim 7, wherein the rapid installation and precise adjustment method is characterized by comprising the following steps of: in the step S04, embedded adjusting bolts (5) are embedded in the four directions of the front, the rear, the left and the right of the cup rim (3) on the short column (2), and in the step S07, the verticality and the elevation of the steel structure column (4) are adjusted by the aid of the embedded adjusting bolts (5) in the four directions.
