| description | The utility model discloses a bridge pile foundation small strain measuring point quick positioning simple device which comprises an operating rod, a positioning framework and a positioning needle, the whole structure is simple, machining and manufacturing are easy, recycling can be achieved, meanwhile, operation of constructors is facilitated, and the arranged excitation point positioning needle is arranged at the center of a pile foundation to serve as a rotating center. The vertical connecting rod is used as a rotating shaft, the vertical connecting rod is rotated through the handle so as to drive the positioning framework to rotate, and three measuring point positions which are convenient and rapid to polish and accurate in relative position can be rapidly found on the top face of the pile head on the basis of the three vertex angles of the regular-triangle-shaped positioning framework. And it is ensured that small strain detection data reflect the integrity of the pile foundation more truly.
