| titleOfInvention | Sample making devices for coal seam hydraulic fracturing test |
| abstract | The utility model relates to a sample making devices is used in coal seam hydraulic fracturing test, include: a supporting member; a base plate fixed to the supporting member with a rectangular groove; the enclosing pressure plate comprises four plate bodies enclosing into a rectangular frame and is clamped in the groove of the substrate to form a rectangular cavity with an open upper end; the partition plate comprises a first partition plate and a second partition plate which are vertically distributed, and can be placed in the rectangular cavity to divide the rectangular cavity into a plurality of sample cavities; and the pressing plates are correspondingly distributed with the plurality of sample cavities and connected with a pressurizing device for pressurizing the samples in the sample cavities. When each layer of structure layer is poured, slurry is kept uniform and flat in the die in a vibration mode, bubbles mixed inside the slurry are extruded out, and it is guaranteed that each sample after waiting for setting is relatively uniform, so that samples with approximately uniform structures can be obtained, and high-quality test raw materials are provided for a fracturing test. |
