Visual experiment system device used for simulating grouting plugging for water inrush of roadways

Abstract

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.

Description

technical field [0001] The invention relates to a visual indoor test system device for plugging research using grouting technology under simulated roadway water inrush conditions. Background technique [0002] In the process of energy mining and tunnel construction, roadway water inrush occurs from time to time. If it is not dealt with in time, it will lead to catastrophic accidents such as submerging mines and underground buildings, causing serious economic losses and casualties. Due to the complexity of engineering geological problems, it is often difficult to find out the source of water inrush and the water guiding structure in a short period of time. The water inrush is concentrated in the water passageway. In order to quickly control the flood and resume production first, it is possible to block the water inrush passageway The method to separate the water inrush area from the production area, stabilize the situation, and then further study how to solve the problem. ...

Problems solved by technology

At present, grouting sealing technology has been used in roadway water inrush rescue and disaster relief projects at home and abroad to obtain some successful experience, but due to the complexity, concealment and unpredictability of engineering geological problems, it is difficult to generalize the problem of roadway water inrush. Some engineering practice experience is not enough to deal with and guide the roadway water inrush grouting plugging treatment under multiple geological conditions and influencing factors
