The invention relates to a two-position reversing valve device for non-granular grouting. The device comprises an outer sleeve, a ratchet transposition mechanism and a nozzle, wherein the ratchet transposition mechanism is arranged in the outer sleeve, and is provided with a movable one-way valve part, a two-position reversing valve part and a spring sliding shaft part. The device is arranged between a drill bit and a drill rod, a mechanical signal transmission and control mode is adopted, normal drilling and grouting signals are transmitted through drilling fluid, and during grouting, a normal drilling circulating medium passage is closed, a grouting passage is opened, and wall protection grout is jetted to a hole wall through the nozzle; at the end of grouting, the normal drilling signal is transmitted, a drilling fluid passage is opened, the grouting passage is closed, and the drilling fluid passes through a drill rod hole, and flows through the circulating medium passage and a gap between the drill rod and a borehole, and flows out of the borehole in a way of carrying residues. The device is simple in structure, high in machinability and safety, applicable to the reversing conduction of a medium during drilling and wall protection, convenient to operate and reliable in use, and the wall protection and drilling efficiency can be greatly improved.
