The invention discloses an earth ramming device for simulating the wall ancient law repairing and ramming technology and a using method thereof. The earth ramming device comprises a frame provided with an earth ramming machine. The earth ramming machine is hinged below the top of the frame. An earth ramming angle electric adjusting mechanism is hinged between the earth ramming machine and the frame. A drill chuck is connected below the earth ramming machine. A ramming head assembly is connected to the drill chuck. A bottom plate of the frame is provided with an earth ramming hole for the ramming head assembly to penetrate through. A dust removing mechanism is arranged on the portion, around the earth ramming hole, of the frame. The earth ramming machine, the earth ramming angle electric adjusting mechanism are connected with a controller. The invention further discloses a using method of the earth ramming device for simulating the wall ancient law repairing and ramming technology. Themethod comprises the steps of ramming repair angle adjusting, synchronous dust removing adjusting, ramming head assembly replacing and ramming repair mode controlling. According to the device and method, the ancient law technology in the construction process of ancient building foundations and wall foundations can be reproduced and simplified, thus labor stick ramming and bundle rammer ramming repair practice in the construction process of the ancient building ancient law can be simulated, and meanwhile, single-time ramming repair and continuous ramming repair can be switched at will.
