The invention relates to a visual experiment system device used for simulating grouting plugging for water inrush of roadways. The visual experiment system device can be used for conducting visual grouting plugging test research based on indoor simulation of grouting plugging of roadways of different inclinations and curvatures on different water inrush pressure and flow rate conditions. The visual experiment system device comprises eight parts including a flowing water system, a roadway model system, a grouting system, a video and picture recording system, a flow monitoring system, a data acquisition system, a support system and a waste liquor collecting system. The flowing water system comprises a water source pipe, a header tank, a water drainage pipe, a water inrush pipeline, control valves and a water tank bracket; the roadway model system comprises a transparent pipeline and crushed aggregates; the grouting system comprises a high-pressure grouting machine, a grouting pipeline and a pressure gauge; the video and picture recording system comprises four digital cameras; the flow monitoring system comprises two flow totalizers; the data acquisition system comprises four pressure sensors and a DT data acquisition instrument; the support system comprises an expansion bracket, an expansion table and a scale; the waste liquor collecting system comprises a waste liquor pipe and a waste liquor barrel.
