Embodiment 1

[0028] The invention provides a device for extracting cracks and pores on the soil surface, specifically as figure 1 with figure 2 As shown, it includes a fixed frame, a camera device 1, a studio 2 and a soil sample fixing platform; in this embodiment, the camera device 1 is a camera or a digital mobile phone.

[0029] The photographic device 1 is fixed on the fixed frame, the lens of the photographic device 1 is set vertically downward, the studio 2 is located below the photographic device 1, and the top surface of the studio 2 is provided with a photographing hole 3, and the photographing hole 3 is arranged opposite to the lens of the photographic device 1 The side wall of the studio 2 is provided with a soil sample placement hole 4 for placing soil samples for experiments. The soil sample placement hole 4 is convenient for placing the experimental soil sample on the soil sample fixed platform. After the soil sample is placed, the soil sample Place hole 4 and close like th...

Abstract

The invention provides a device and a method for extracting soil surface crack pores, and relates to the basic technical field of soil. The device comprises the following steps that a photo taking device is fixed on a fixing frame; a lens of the photo taking device is arranged in a downward direction; a photostudio is positioned under the photo taking device; a shooting hole is formed in the top surface of the photostudio, and is arranged in a way of being opposite to the lens of the photo taking device; a soil sample placing hole is formed in one side wall of the photostudio; a soil sample fixing platform is arranged inside the photostudio and is positioned right under the shooting hole; the soil sample fixing platform comprises a base and a placing platform; the base is fixed onto the bottom of the photostudio; the placing platform is fixed on the base; a soil sample placing groove is formed in the middle of the fixing platform; a plurality of target points are arranged around the soil sample placing groove; the included angle between the two adjacent target points is 45 degrees. The device and the method have the advantages that the operation is convenient; the test and controlprecision is high; the change process of each parameter of soil surface cracks / pores and the like can be clearly shown again; the application range is wide.

Description

technical field [0001] The invention relates to the field of soil foundation technology, in particular to a device and method for extracting cracks and pores on the soil surface. Background technique [0002] Soil fissures are an important parameter to characterize soil runoff and erosion processes. Fissures will increase soil preferential flow and the occurrence of large fissure water, which will reduce soil block stability, shear strength, and increase soil parameters such as hydrological conductivity. Fissures will change the distribution of water, air, and temperature in the soil, but it is currently difficult to quantitatively extract soil fissures. [0003] Therefore, the quantitative extraction of the number and distribution of soil fissures is beneficial to the analysis of soil parameters and the control of surface runoff and soil erosion. Contents of the invention [0004] In order to overcome the deficiencies in the above-mentioned prior art, the present inventi...
