An evaluation instrument for soil erosion resistance under wind erosion, water erosion and coupled erosion

Abstract

The invention discloses an evaluation instrument for soil erosion resistance under wind erosion, water erosion and coupled erosion, with the purpose of simulating the real soil wind erosion, water erosion and coupled erosion environment, and reflecting the characteristics of soil resistance to wind erosion, water erosion and coupled erosion , the technical scheme adopted is: including a base set horizontally, a soil sample box is set on the base, an inlet and an outlet are respectively provided at both ends of the soil sample box in the length direction, the inlet is connected to a blower or a water source, and the outlet is connected to measure Data collection and processing system for soil corrosion resistance. The soil sample box has an included angle between the length direction and the horizontal plane of the base. The position of the entrance is higher than the position of the exit. The soil sample box includes a soil sample room for placing soil samples , the soil sample chamber communicates with the inlet and the outlet, the upper end of the soil sample box is provided with a precipitation frame, the precipitation frame is fixed on the base through a pipeline, and the pipeline is connected with the water source, and the described precipitation frame is provided with a number of pipes connected Nozzle, the nozzle is located at the upper end of the soil sample chamber.

Description

technical field [0001] The invention belongs to the technical field of geotechnical tests, and in particular relates to an evaluation instrument for soil corrosion resistance under wind erosion, water erosion and coupled erosion. Background technique [0002] At present, the test equipment and measurement methods for the anti-corrosion properties of soil under the action of flowing water and wind erosion are relatively extensive, and the obtained results are difficult to truly reflect the anti-corrosion properties of soil. The known simulated rainfall system is too extensive in terms of equipment and operation methods, and it is difficult to accurately measure the anti-corrosion characteristics of soil under the conditions of water erosion and wind erosion. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention proposes an evaluation instrument for soil erosion resistance under wind erosion, water erosion and coupled erosi...
