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

[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] 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.

[0036] The experimental equipment that can observe the migration of the soil wetting front and collect the soil midflow in layers mainly includes: the waterproof device 6 at the bottom, the tempered glass 2 on the side, the fine gauze 9, the iron net 10, the layered collection device 7 for the soil midflow, and the guide. flow device4.

[0037] Among them, (1) the waterproof device 6 at the bottom ...

Abstract

The invention discloses a device for collecting a subsurface flow via vertical extrusion. The device comprises a sleeve and a drive rod; the drive rod is positioned in the sleeve; scales are arrangedon the outer wall of the sleeve, and the upper end of the sleeve is open while the lower end of the same is connected with a taper part; multiple radial holes are formed in different axial positions of the sleeve; a telescopic moving component is arranged in each radial hole; one side, facing the interior of the sleeve, of each telescopic moving component stretches into the sleeve and is providedwith a lower bevel; a telescopic collection cavity is arranged on one side, facing the outside of the sleeve, of each telescopic moving component; a soil moisture sensor is arranged in the telescopiccollection cavity; first push pieces of which the quantity is consistent with that of the telescopic moving components are arranged on the drive rod; the first push pieces are used for pushing the telescopic moving components outwards; an upper bevel matched with the corresponding lower bevel is arranged on the bottom surface of each first push piece. The device provided by the invention has the advantages that the soil with different depths can be collected and the water content of the soil can be analyzed, so that the migration condition of the soil wetting front and the response relation thereof to rainfall can be more objectively reflected.

Description

technical field [0001] The invention relates to the technical field of hydrological experiment research, in particular to a device for collecting soil midflow through vertical extrusion. 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 surfaces...
