The tops of the outer leg 3 and the inner leg 4 respectively slide and extend into the outer slot 8 and the inner slot 7 at the bottom of the outer frame 1.

[0031] The jack 6 is located below the inner frame 2, and the jack 6 is used to apply pressure to the pile body to detect its bearing capacity and deformation conditions.

[0032] A U-shaped frame 5 is slidably arranged between the four outer legs 3 and the four inner legs 4. Pulley 12 is installed at the four corners of the bottom of the U-shaped frame 5 to realize the movement of the device. In addition, hydraulic cylinders 10 are installed at the four corners of the bottom of the outer frame 1. One end of the piston rod of the hydraulic cylinder 10 is fixedly connected to the top of the U-shaped frame 5.
