| titleOfInvention | Sample preparation device for coarse-grained soil triaxial test and application method thereof |
| abstract | The invention discloses a sample preparation device for a coarse-grained soil triaxial test, and belongs to the technical field of soil body testing apparatus. The sample preparation device comprises a pressure chamber pedestal, an outer pressure chamber cylinder, a rubber membrane, porous stone, an inner pressure chamber cylinder, an isolating cloth cover, a funnel, a cylindrical compaction device and an annular compaction device, wherein the porous stone is arranged inside a groove in the pressure chamber pedestal; the lower end of the outer pressure chamber cylinder is fixed on the pressure chamber pedestal; the rubber membrane tightly covers the inner surface of the outer pressure chamber cylinder; the inner pressure chamber cylinder for containing coarse aggregates is arranged inside the outer pressure chamber cylinder; the isolating cloth cover tightly covers the outer surface of the inner pressure chamber cylinder. The invention further discloses an application method of the device. The sample preparation device disclosed by the invention cannot cause deformation of the coarse aggregates; meanwhile, the rubber membrane is protected by a sand layer to avoid breakage; the specimen can be prevented from oversize disturbance due to the cylinder lifting process in the pressure chamber; the sample preparation device is quick in specimen filling speed and high in efficiency, and can effectively ensure normal operation of the test. |
