Reinforcement cage for drilled press-grouting piles and molding device thereof

The invention discloses a reinforcement cage for drilled press-grouting piles and a molding device thereof, and aims to solve the problem of weak structural strength in the connecting place of two reinforcement cage units. The reinforcement cage for the drilled press-grouting piles comprises at least two sections of reinforcement cage units; and the reinforcement cage units are connected end to end; the reinforcement cage units comprise two opposite stiffening ribs, multiple main reinforcements fixed with the two stiffening ribs at the same time, and spiral hoops spirally fixed with the multiple main reinforcements. The reinforcement cage for the drilled press-grouting piles is characterized in that external threads are arranged at the upper and lower ends of the main reinforcements; the external threads on the lower sides are in threaded fit with connecting sleeves; and the upper and lower ends of the connecting sleeves are of opening structures.
