Pile foundation-cement soil annular contact surface test mold

The utility model relates to a pile foundation-cement soil annular contact surface test mould which comprises a bottom plate, two side plates, two fixed baffles, an inner ring baffle and a driving piece, the bottom plate is arranged in a square shape, the two fixed baffles are vertically installed on the two opposite side faces of the bottom plate respectively, and the inner ring baffle is arranged on the bottom plate. The two side plates are vertically installed on the other two opposite side faces of the bottom plate respectively, a pouring cavity is defined by the bottom plate, the side plates and the fixing baffles jointly, and the inner ring baffle is installed in the pouring cavity in a sliding mode and can move in the direction close to or away from one fixing baffle under driving of the driving part. Through the arrangement, a sample simulating the pile foundation-cement soil annular contact surface can be obtained by using the mold, an engineer can conveniently carry out a test, the simulation test c
