The invention discloses a drainage consolidation apparatus of a soil sample and a preparation method. The drainage consolidation apparatus comprises a bottom plate, a front panel, a rear panel, a left panel, a right panel, an upper pressing plate, two supporting rods, two pressure bearing rods, a lever group and a swing bolt. By utilizing a lever principle, the force is easy to apply, the applied force is easy to control, the load is constant during the consolidation process, and the current situation that no apparatus for performing the drainage consolidation for large-sized soil sample in a laboratory is changed; and compared with the traditional soil sample drainage consolidation way, the apparatus is simple in operation process, simple in structure and easy to disassemble and move.
Description
technical field [0001] The invention relates to a soil sample drainage consolidation device and a preparation method, belonging to the field of test devices. Background technique [0002] With the technological development of the dredging industry, the research on the interaction between water, machine and soil has become more and more in-depth. There are many soil-related processes in dredging construction, such as jetting soil breaking, reamer rake head cutting, etc. The problems they face are very complicated, and often need to be studied through large-scale indoor experiments. In order to prevent the accidental results of the research, repeated experiments are required , at the same time, in order to obtain regular results, it is necessary to provide a single soil condition, which puts forward requirements for the preparation of large-scale soil samples with uniform properties. Moreover, soil sample preparation is the primary link in the process of studying soil propert...
