referring to fig. 1-4, a pile foundation self-balancing detection device according to an embodiment of the present utility model includes two connection plates 10 symmetrically arranged up and down, a circumferentially distributed hydraulic expansion device 16 is fixed between the two connection plates 10, the two hydraulic expansion devices 16 are connected through a hydraulic pipe 19, a circumferentially distributed lower displacement rod 17 is fixed on an upper end surface of the connection plate 10 at a lower side, a circumferentially distributed upper displacement rod 15 is fixed on an upper end surface of the connection plate 10 at an upper side, support blocks 13 are respectively arranged on end surfaces of the connection plates 10 at the upper side and the lower side, which are far from the hydraulic expansion device 16, rotating rings 12 are respectively rotatably matched in end surfaces of the connection plates 10 at the upper side and the lower side, which are far from the hydraulic expansion device 16, threaded cavities 22 are respectively arranged in each rotating ring 12, and support components can be arranged in the two threaded cavities 22;

the support assembly comprises a threaded sleeve 18, a telescopic screw 21 is in internal threaded fit with the threaded sleeve 18, a fastener 20 is in rotary fit with the periphery of the telescopic screw 21, and certain friction exists between the fastener 20 and the telescopic screw 21 in rotation, so that the telescopic screw is kept relatively static under the action of larger external force.

Positioning cavities 14 distributed circumferentially are arranged in each supporting block 13, and the positioning cavities 14 are convenient for positioning and welding supporting steel bars.

Each connecting plate 10 is provided with a locating hole 11 in the end face of one side far away from the hydraulic telescopic device 16, one end of each locating hole 11 far away from the hydraulic telescopic device 16 is provided with an opening, and the locating holes 11 are convenient for locating and welding the reinforcement cage.
