Production process of large-caliber SC shape steel mixed pile or column
The invention relates to a production process of a large-caliber SC shape steel mixed pile or column. The production process comprises the following steps: a matched tool is manufactured, disc round steep is stretched, and an outer reinforcement cage and a reinforcing cage rib are manufactured; the outer reinforcement cage is welded with a pull rod, and the reinforcing cage rib is put in the outer reinforcement cage after coating an upper end plate; a middle joiner is connected with a keel, the assembled outer reinforcement cage coats a steel pipe, a head plate is assembled with a steel cylinder, and a steel pipe core rod is coated with a rubber pipe to be inserted in the structural part; a pile top section structure, a pile bottom section structure and a standard section structure are manufactured in sequence and are assembled, the assembled structural part is lifted into a steel mold, the mold is closed, the centrifugation is performed after the pumping of concrete, and the normal-temperature maintenance is performed; when the strength of the concrete reaches 10% of a design value, the steel pipe is pulled out; and when the strength of the concrete reaches 60% of the design value, the mold is disassembled, and the product is formed through assembling. The production process can manufacture an ultralong prestress concrete pipe pile with large diameter.
