The utility model provides a reducing prefabricated concrete tubular pile, including the pile body, the pile body has a hollow structure who is used for filling out the core concrete, and hollow structure's top is round platform shape structure, and its below is cylindrical structure, and the round platform appears the aperture of structure by last down grow from childhood, and it is sharp that the lower extreme of pile body passes through the stake of frustum structural connection, the lower extreme of stake point has a sharp portion of awl, and the both sides of stake point have bar spout, first zhi guanjie and second zhiguanjie respectively, second zhiguanjie can slide about in the bar spout to change the diameter of stake point. The utility model discloses the aperture of the hollow structure's of well pile body round platform shape structure is by last down grow from childhood to increased and filled out the combination degree between core concrete and the pile body, on the other hand, but the stake of reducing is sharp below the pile body, through enlarging the sharp reducible pile body of the diameter side friction resistance in the secret soil layer of impressing of stake, and can be in exerting the secret soil layer of can impressing the pile body under the circumstances of little pressure.
