Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Such as Figure 1-3 As shown, a device for simulating and observing the infiltration characteristics of slope rainfall in deep layers according to the present invention includes: a slope soil observation unit, a deep soil water collection unit, and a rainfall simulation unit.

[0030] Slope soil observation unit: 4mm iron plate is used to make the surrounding partitions for observing the slope soil. The upper and lower sides are not closed, but the surroundings are closed. Different specifications can be set for test requirements, and different slopes can be formed. The box can be backfilled with soil samples of different textures according to the test requirements.

[0031] Deep soil water collection unit: the depth can be set at 1.5-2.5m, which can collect the amount of water infiltration in the soil section at a depth of 1.5-2.5m b...

Abstract

The invention relates to a device and method for simulating and observing the infiltration characteristics of rainfall in deep layers on a slope. The device includes: a slope soil observation unit that can be set with different slopes and soil textures, a deep soil water collection unit that can collect deep seepage of soil water at a specific depth, and a rainfall simulation unit that can simulate different rainfall amounts and rain intensities. The method is as follows: establish a slope soil observation unit, install a deep soil water collection unit in the unit, and use the rainfall simulation unit to set up rainfall events with different characteristics, and determine the occurrence characteristics of water in the water collection unit, including water volume and occurrence time. Under different rainfall conditions, different soil textures, different slope angles, and the characteristics of the deep leakage of soil moisture at a specific depth on the slope provide an experimental basis for the analysis of soil moisture balance in the slope environment.

Description

technical field [0001] The invention relates to the occurrence point and quantitative observation of the deep-layer infiltration process of slope rainfall, in particular to a simulation observation device and method for the characteristics of slope rainfall deep-layer infiltration. Background technique [0002] The amount of soil water infiltration in deep layers is an essential and important quantitative parameter for the study of soil water balance, the process of rainfall replenishment to groundwater, and the study of soil and water conservation on slopes. The way to obtain the deep seepage of soil moisture has not been clear for many years. It is mainly estimated by means of mathematical model simulation, soil moisture content change process, and soil water potential difference. The obtained values ​​vary greatly and are not universal enough. Conduct self-comparative analysis. The method of direct observation of slope soil moisture infiltration is considered to be indep...
