Embodiment Construction

[0020] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0021] like figure 1 and figure 2 As shown, in order to observe the soil moisture infiltration process in the ring after the infiltration ring is struck into the soil, the present invention designs a detachable indoor test soil tank device. The device consists of a detachable soil tank, a detachable infiltration ring and a see-through plexiglass plate. After the infiltration ring is hit into the soil in the soil tank, the soil in the ring is radially cut into two halves with a steel plate, and one of the half rings and the soil therein are removed. Use a plexiglass plate to seal and fix the soil in the remaining half-ring for a visual test of the soil moisture infiltration process and to obser...

Abstract

The invention discloses a visual testing device for observing the infiltration process of soil moisture in a ring-type infiltration instrument, and a method using the same. The visual testing device comprises two half soil bins, half soil bin connecting plates, a perspex sheet, bolts for fixing the perspex sheet and the half soil bin connecting plates, bolts for fixing the two half soil bins, a partitionable infiltration ring and an infiltration ring connecting plate. With the device and the method, the influence of preferential flow to the whole soil infiltration process can be observed, so that basis is provided for further studying the infiltration process of soil moisture in a ring can be provided, and effective basis is provided for analyzing the accuracy of measuring results of the ring-type infiltration instrument and providing an improved device for eliminating the influence of the preferential flow.

Description

technical field [0001] The invention relates to the field of measurement of soil infiltration characteristics, and more particularly relates to a visual test device and method for soil moisture infiltration process in a ring type infiltration instrument. Background technique [0002] Soil infiltration performance refers to the maximum possible infiltration rate of soil under given conditions, which is an inherent property of soil; it is closely related to soil erosion, soil erosion, crop irrigation management, and solute transport. Many scholars believe that the measurement of soil infiltration performance is an indicator of soil properties, so there are many measurement methods of soil infiltration rate, such as double ring method, disc infiltration method, artificial rainfall method, rainfall-inflow-water accumulation method, rainfall - Inflow-production flow method, line source inflow measurement method, etc. Among them, the double-loop infiltration meter is a widely use...
