The utility model relates to a novel power-pulled soil taking system, which comprises a power supply system, a pulling system and a soil taking and unloading system, wherein the soil taking and unloading system comprises a U-shaped hanging ring, a soil storage sleeve, U-shaped fixed hanging rings connected to the outer sidewall of an opening in the upper end of the soil storage sleeve in a welding way, blade feet connected to the outer sidewall of an opening in the bottom of the soil storage sleeve in the welding way, a limiting rod connected to the inner sidewall of the opening in the bottom of the soil storage sleeve in the welding way, a valve rotating shaft connected with the opening in the bottom of the wall of the soil storage sleeve and a rotating movable valve connected with the valve rotating shaft in the welding way and overturned to realize sealing and opening functions through the valve rotating shaft; the U-shaped hanging ring is connected with the U-shaped fixed hanging rings through a rope, and is connected with a power pulling rope. According to the novel power-pulled soil taking system, the soil taking and unloading system is inserted through the blade feet to realize a soil taking function, and is connected with the pulling system through a connecting pulley B, and a soil unloading function is realized through the rotating movable valve, so that the technical problem that a soil body in a PHC (pre-stressed high-strength concrete) pipe pile with a small aperture is difficult to take out is effectively solved, the cost is lowered, and the working efficiency is improved.
