Abstract
The invention discloses a multi-field coupling effect indoor column immersion test device. The device comprises a sample bearing barrel, a stress transmitting cushion block, a temporary liquid storagepool, a bottom sealing cushion block and a control valve. The bottom sealing cushion block and the bottom of the sample bearing barrel are combined. The temporary liquid storage pool is located on the upper part of a sample in the sample bearing barrel. The stress transmitting cushion block is located on the upper part of the temporary liquid storage pool. The control valve comprises a liquid inflow control valve and a liquid outflow control valve. The device is simple and effective, has strong applicability, and effectively solves the problem that the existing device has a single purpose andpoor effects.
Description
technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a multi-field coupling action indoor column immersion test device. Background technique [0002] The study of the mechanical properties and deformation laws of rock-soil bulk bulk has been a hot topic in the field of geotechnical engineering in recent years. Mining has important guiding significance. At present, heap leaching and in-situ leaching have become an effective and economical extraction process for extracting useful components in lean ore, tailings, rare earth ores and other minerals. For useful components in low-grade ores, refractory ores, and waste rocks, heap leaching is a relatively effective extraction method; however, due to the stress field and the The seepage field generated by the infiltration of ore leaching solution and the coupling effect of chemical field and other fields are destroyed, which changes the effective stress born...
