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 simulated observation device and method for deep infiltration characteristics of slope rainfall. The device comprises a slope soil body observation unit capable of setting different slopes and soil textures, a deep soil water catchment unit capable of collecting soil water deep infiltration of a specific depth slope, and a rainfall simulation unit capable of simulating different rainfall and rainfall intensity. The method comprises the following steps: establishing the slope soil body observation unit, installing the deep soil water catchment unit in the unit, setting rainfall events of different characteristics by utilizing the rainfall simulation unit, and by measuring the water quantity occurrence characteristics in the catchment unit, including water quantityand time of occurrence, determining the soil water deep infiltration quantity characteristics of the specific depth slopes at different slope angles on different soil textures under different rainfall conditions, and providing an experiment basis for soil water balance analysis for 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...
