Soil infiltrometer

Abstract

The invention relates to the technical field of edaphology, and in particular relates to a soil infiltrometer. The soil infiltrometer comprises a sample container, a first impounding reservoir, a second impounding reservoir and a water pump, wherein the sample container is positioned in the first impounding reservoir; the first impounding reservoir is positioned in the second impounding reservoir; the first impounding reservoir is greater than the sample container; the top of the sample container is opened, and the sample container is used for accommodating a soil sample; the water pump is used for injecting liquid from the second impounding reservoir into the first impounding reservoir, so that the liquid in the first impounding reservoir can flow through the soil sample from the top of the sample container and is discharged from the bottom of the sample container. The invention aims at providing the soil infiltrometer, a test device is simple, the cost is low and the carrying is convenient; a researcher doing a test outdoor can measure a soil infiltration parameter by adopting a constant head test method conveniently.

Description

technical field [0001] The invention relates to the technical field of soil science, in particular to a soil infiltration instrument. Background technique [0002] In recent years, my country's soil science has developed extremely rapidly, and my country's soil classification research has gradually converged with the American system. The Chinese soil classification system has become one of the four major international classification systems. The research on the field of soil is getting more and more in-depth, and there are more and more research methods on soil permeability. Soil permeability is one of the important physical properties of soil. Soil permeability coefficient is an important parameter used to reflect soil permeability, which is often measured in studies of soil water balance, irrigation, drainage, soil improvement, engineering geology, hydrogeology, and soil and water conservation. The development of penetration test devices is also becoming more and more di...

Problems solved by technology

[0003] The constant head test method is a commonly used penetration test method in the laboratory; the constant head test device used in the laboratory has a complex structure and is not easy to carry, which is not conducive to the researchers who conduct tests outdoors to measure the soil permeability coefficient through the constant head test method
