The invention discloses a pile extracting clamp which is integrally of a T shape. The pile extracting clamp comprises a horizontally-arranged hollow transverse tube and a vertically-arranged hollow longitudinal tube; wherein the upper end and the lower end of the hollow longitudinal tube are opened; the upper end of the hollow longitudinal tube is communicated with the hollow transverse tube; a front side plate and a rear side plate of the hollow longitudinal tube are provided with a plurality of rows of preserved holes from top to bottom; a horizontal moving chuck is arranged in a left half section of the hollow transverse tube; and a horizontal fixed chuck is arranged in a right half section of the hollow transverse tube. According to the clamp, actions forces are applied onto an H-shaped steel flange plate and a web plate; the area of the action forces is large; the centralized stress is reduced; the damage to the pile is reduced; in addition, the clamp is very convenient to operate.
