Abstract

The invention relates to a soil infiltration process measuring instrument, in particular to an improved double-ring infiltration process visual test device. The device comprises an inner arc plate and an outer arc plate, a horizontal fixed plate and a vertical fixed plate which are respectively connected with the inner arc plate and the outer arc plate, a vertical connecting plate, and a transparent perforated organic glass plate. In order to observe an advancing process of a wetting front in an infiltration process of a double-ring infiltration test, the device solves the problems that a vertical moisture content distribution test has defects and the influence of preferential flow on the infiltration test is not considered. The improved double-ring infiltration process visual test device is simple in structure and low in manufacturing cost; a double-ring infiltration device is combined with the organic glass plate, so that the change of the wetting front can be observed, and the change of moisture contents of different positions can be measured.

Description

technical field [0001] The invention relates to the field of field soil infiltration characteristic tests, in particular to an improved visual test device for the water infiltration process in a double-ring infiltration instrument. Background technique [0002] Infiltration is the process of rainfall, irrigation, flooding and other water entering the soil, and is an important part of the soil water cycle. Soil infiltration affects surface runoff and groundwater recharge. The in-situ infiltration test is an important method to measure the vertical permeability coefficient of the soil layer in the aerated zone in the field. Occupies an important position in the acquisition of , and the double-ring method is commonly used. The double-ring method is to ensure that the inflow and infiltration of the inner ring water is a vertical one-dimensional infiltration, so as to solve the vertical saturated permeability coefficient of the soil layer. The double ring is two concentric rin...
