PURPOSE: A rotary valve for grouting concrete is provided to automatically connect distribution pipes installed in a certain position to supply pipes sequentially. CONSTITUTION: A supply pipe(1) is connected to a supply pipe connecting part(40) installed in one side of an outer frame(10). A connecting device(21) of a rotary plate(20) is connected to the other side of the supply connecting part by a connecting pipe(50). The connecting device is adhered to a connecting pipe(11) formed on the front end of the outer frame. A distribution pipe(2) is connected to the connecting pipe thus concrete is transferred to the distribution pipe from the supply pipe. If the supply pipe is combined to the supply pipe connecting part, the concrete injected from the supply pipe by the rotation of the rotary plate is injected to the distribution pipe selectively via the connecting pipe. Thus, the concrete is grouted in a certain position.
