The invention relates to the technical field of concrete pipe piles, in particular to a stable concrete pipe pile and a using method thereof, the stable concrete pipe pile comprises a plurality of concrete pipes, and connectors are arranged at the ends of the concrete pipes. According to the stable concrete pipe pile and the using method thereof, the steel sheets on the outer side of the concrete pipe are used for supporting the concrete pipe along the pipe sleeve, the limiting length of the pipe sleeve to the concrete pipe is prolonged, the acting force of the concrete pipe to the inserting opening in the pipe sleeve is reduced, and when the steel sheets enter soil along with the concrete pipe, the spiral deflection appearance of the steel sheets is subjected to the counteraction of the soil; when the pile tip moves downwards in the soil, the steel sheets bent upwards rotate and tighten anticlockwise, the steel sheets bent downwards rotate and tighten clockwise, the concrete pipe is pushed to rotate to a cer
