Problems solved by technology

[0005] Although the existing device that directly observes the movement of soil moisture through a glass window makes the observation more intuitive, the movement of moisture inside the soil is more complicated. The glass window only reflects part of the facts, and cannot accurately understand the inside of the soil layer that is invisible to the naked eye. Demonstration of the soil wetting front

Embodiment Construction

[0038] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] combine Figure 1 to Figure 4 As shown, a soil tank can be used to observe the migration of the soil wetting front and collect the soil flow in layers. The length, width and height of the soil tank in the experimental design are 5m×2m×1.3m, which can simulate the rainfall process on a large scale. Response relationship of different underlying surface, slope, rainfall intensity and previous soil moisture content to soil moisture migration.

[0040] The experimental equipment that can observe the migration of the soil wetting front and collect the soil midflow in layers mainly includes: a horizontal rotary extrusion collection soil midflow device, a bottom waterproof device 6, a side tempered glass 2, a fine gauze net 9, an iron net 10, Soil midstream layered collection device 7 and diversion device 4.

[0041] Among them, (1) the water...

Abstract

The invention discloses a device for horizontally rotating and extruding the middle flow of collected soil, which comprises a sleeve and a driving rod. The driving rod is located in the sleeve. There are multiple radial holes at different positions, and a telescopic moving part is arranged in each radial hole. One side of the telescopic moving part extends into the sleeve and is provided with two first guide surfaces. The other side of the telescopic moving part A telescopic collection cavity is provided, and a soil moisture sensor is provided in the telescopic collection cavity, and the first pusher is provided on the driving rod with the same number as the telescopic moving parts; the advantage is that it can be buried in the soil and can collect and collect soil at different depths. Analysis of its water content, thus making it more objective to reflect the migration of the soil wetting front and its response to rainfall.

Description

technical field [0001] The invention relates to the technical field of hydrological experiment research, in particular to a horizontal rotary extrusion device for collecting soil midstream. Background technique [0002] Under the dual influence of climate change and human activities, the evolution of water cycle in the basin is undergoing profound changes. Climate change affects the hydrological cycle by changing precipitation, temperature, sunshine, wind, relative humidity, etc., and then changes the temporal and spatial distribution of precipitation, runoff, evaporation, soil moisture and other hydrological elements. Human activities affect the hydrological cycle process by changing the underlying surface of the basin and the spatio-temporal distribution pattern of water. Therefore, the response relationship between soil moisture change and runoff during the rainfall process, or the response relationship between different slopes, rainfall intensities, and underlying surfa...
