PURPOSE: A pile measuring sensor is provided to unify sensors being utilized for a shaft loading test and horizontal loading test on pile and to reduce a construction period required for installing a measurement device. CONSTITUTION: A pile measuring sensor comprises a front end fixing unit, a center fixing unit(10), a sensing unit(22), a connection rod, a driving tube(T), and a fixing pin(20). The front fixing unit is fixed to the lower front end of a pile. The center fixing unit is arranged in the middle part of the pile. The sensing unit measures an axial load and an inclination. The connecting rod is installed in between the front end fixing unit or the center fixing unit and the sensing unit. The driving tube is connected to a pressure tube with a pressure liquid connection unit as a medium, thereby being expanded or contracted by using a fluid being supplied through the pressure tube. The fixing pin is touched to the driving tube, thereby being projected to the outside of the front end fixing unit or the center fixing unit or being renewed correspondently to the expansion and contraction of the driving tube.
