Embodiment Construction

[0060] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0061] Such as figure 1 The rainfall erosion measurement box shown includes a box body 1 and a tilting mechanism 2. The box body 1 is used to carry soil. The box body 1 can be welded by a plurality of steel plates with a length, width and height of 2000mm*1000mm*800mm. Cuboid without cover;

[0062] Tilting mechanism 2 is connected with box body 1, is used for pushing box body 1 and makes the height of one end of box body 1 lower than the height of the other end of box body 1; That is to say, the effect of tilting mechanism 2 is to make box body 1 The tilt occurs, generally according to the length direction, one end is high and the other end is low, and the tilt is realized.

[0063]After the push of the tilting mechanism 2, the end surface of the lower end of the box body 1 is provided with drainage holes 3, preferably a plura...

Abstract

The invention relates to the technical field of water and soil loss, and particularly relates to a rainfall erosion measuring box. The rainfall erosion measuring box comprises a box body and a tilting mechanism, wherein the box body is used for bearing soil, and the tilting mechanism is connected with the box body for pushing the box body to make one end of the box body lower than the other end of the box body; a drainage hole is formed in the end face at one end which is lower when the box body is pushed by the tilting mechanism; a water collector is arranged above the end face and used for collecting water reserved by inclining soil on the top face of the box body. The invention further relates to a soil erosion amount measuring method with the rainfall erosion measuring box. The box provided by the invention can simulate a field environment in a laboratory or other non-field environments to measure water and soil loss, particularly, data of direct surface runoff and interflow can be acquired, and thus the box is convenient for scientific analysis and research workers to use.

Description

technical field [0001] The invention relates to the technical field of soil erosion, in particular to a rainfall erosion measurement box and a method for measuring soil erosion. Background technique [0002] In the process of development and utilization of mineral resources, due to changes in geological conditions induced by human activities, large-scale disorderly mining has caused serious damage to the ecosystem in history, and serious geological environmental problems have caused a series of problems in the mining process, such as Serious geological disasters, severe rocky desertification, barren vegetation, occupying a large amount of land, serious soil erosion, direct or indirect pollution of water sources and air pollution. In the process of mine management, it often causes secondary damage to the ecosystem, and different slope and soil thickness control measures play an important role in the benefits of water and soil conservation. Therefore, aiming at the above poin...
