A soil sample drainage consolidation device and preparation method

Abstract

The invention discloses a soil sample drainage consolidation device and a preparation method thereof. The soil sample drainage consolidation device comprises a bottom plate, a front panel, a rear panel, a left panel, a right panel, an upper pressing plate, two support rods, two bearing pressure rods, a lever group, a swing bolt and a water collecting tray. The soil sample drainage consolidation device is capable of collecting discharged water during a soil sample solidification process through the water collecting tray, so that the displacement volume is measured; compared with a traditional soil sample drainage consolidation mode, the soil sample drainage consolidation device is simple in operation process, simple in structure and easy to detach and carry, and can be used for changing the situation that no drainage consolidation device for large-scale soil samples exists in a laboratory.

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...

Problems solved by technology

[0004] Purpose: Aiming at the problem that the current drainage consolidation method is not suitable for large-scale soil samples, this invention proposes a drainage consolidation device and preparation method for soil samples, which uses the principle of leverage to double the applied load of soil samples, and the applied pressure is convenient for adjustment and consolidation. The load is stable during the process, and the drainage volume can be measured to estimate the moisture content and property changes of the soil sample in real time, and the structure is simple, the operation is simple, and there is no energy consumption.
