Abstract

The invention discloses a soil saturation experiment and permeation experiment compound device. The device mainly comprises a soil saturation experiment device and a soil permeation experiment device. The soil saturation experiment device and the soil permeation experiment device are connected through a transparent pipeline with double scales and a connecting pipeline. The upper end of the transparent pipeline can be connected with a gas pressurizing device with air pressure value reading function, and the whole compound device is supported by a bottom support. The device is a simple experiment device integrating a soil saturation experiment and a soil permeation experiment uniquely in the prior art, the device can be made of organic glass or stainless steel, rubber and other low cost materials, operability of a soil sample determination experiment is promoted on the whole, for the determination experiment with the large soil sample class number, labor resources are saved, the utilization efficiency of the device and time is improved, the gas pressurizing device is used for determination of ordinary soil sample parameters and especially can be used for soil sample parameter determination with high clay content and dense soil particle arrangement, the experiment time can be greatly shortened, and the time cost is reduced.

Description

technical field [0001] The invention relates to the technical field of geotechnical tests, in particular to a composite device for soil saturation experiments and infiltration experiments. Background technique [0002] In many fields such as soil physical properties, agricultural water conservancy engineering and hydrogeology, it is necessary to understand and master the movement law of soil moisture. Soil saturated moisture content and soil permeability coefficient are two basic parameters to master the law of soil water movement. For the soil with a low clay content, it is not necessary to soak the soil under high water pressure during the soil soaking stage of the soil saturation experiment. It is only necessary to ensure that the water level is slightly lower than the upper port of the ring knife. Generally, it can be saturated in about 24 hours; Similarly, too much pressure is not required in normal pressure or variable pressure permeability coefficient experiments. Ho...
