| titleOfInvention | Device and method for quickly preparing multi-stage mixed proportioning coal rock standard test piece |
| abstract | The invention discloses a device and a method for quickly preparing a multi-stage mixed ratio coal rock standard test piece. For a broken surrounding rock roadway, grouting reinforcement is an effective way for controlling surrounding rock of the roadway, in order to test the specific mechanical property of a coal rock mass after slurry reinforcement with different solid-liquid ratios, the coal rock mass and a grouting material are made into a proportioning coal rock standard test piece under a laboratory scale, the original proportioning coal rock standard test piece is single in preparation method, the span range is large in time efficiency, the forming time and the forming quality cannot be controlled manually, the size of the test piece cannot meet the specific requirements of experimental parameter testing to a great extent, and solids can be settled at the bottom of a model under the influence of gravity in liquid, so that the test piece is inhomogeneous. The three solid-liquid material mixing modes enable the molded test piece to be more homogeneous, and the sealed heating and rotating circulation enable the test piece to be molded more quickly, the problems of manual slurry stirring time and long test piece molding waiting time can be effectively solved, the molding quality of the standard test piece is improved, and the preparation process of the grouting proportioning standard test piece is simplified. |
