1. A testing device for a resistance between a concrete and a wall, comprising a counter-force frame, a driving mechanism, an outer cylinder (18), a rotor, and a plurality of pressurization mechanisms, wherein a bottom of an inner side of a counter-force frame is provided with the driving mechanism, an output shaft of the driving mechanism is connected to the lower shaft (10) of the rotor, the rotor is placed inside the outer cylinder (18), space between the rotor and the outer cylinder (18) is filled with a concrete specimen (24); the pressurization mechanisms are symmetrically arranged at a top of the concrete specimen (24), tail end of each of the plurality of pressurization mechanisms is mounted on the upper portion of the counter-force frame, wherein axial load is applied vertically downward to the concrete specimen; the counter-force frame is structurally fixed with the outer cylinder (18) through supporting columns (23), thereby forming an integrated load-bearing system to restrain radial expansion and ensure stable pressurization; and the plurality of pressurization mechanisms, the rotor and the driving mechanism are connected to a data receiver (28); and the rotor comprises a rotor base plate (11) and rotor side walls (15), a lower rotor shaft (10) penetrates the rotor base plate (11), a top of the lower rotor shaft (10) is connected to an upper rotor shaft (13) by means of a torque sensor (16), and the upper rotor shaft (13) is connected to the rotor side walls (15) by means of spoke plates (14).
