Formwork support (snap in circular template) → Formwork support (reinforcement) → Formwork closure (operate from bottom to top one by one) → Formwork closure (staggered connection to increase firmness) → Reinforcement with steel strips (parallel, consistent strength) → Steel strip spacing of 20-30cm → Four 5 * 10cm wooden squares added around → The bottom circular plane of the template should be 0.5-1cm above the ground and filled with concrete → Typical column head reinforcement (protruding with arbitrary cutting ability) → Demolition of the formwork (dismantling the reinforcement in sequence)
