Abstract

The invention discloses an evaluation instrument of soil mass corrosion resistance under wind erosion, water erosion and coupling erosion, and aims at simulating the real wind erosion, water erosion and coupling erosion environments of a soil mass, and reflecting the characteristic of resisting wind erosion, water erosion and coupling erosion, of the soil mass. The following technical scheme is adopted: the evaluation instrument comprises a horizontally-arranged base, wherein a soil sample box is arranged on the base; an inlet and an outlet are formed at the both ends in the length direction of the soil sample box respectively; the inlet is connected with a blower or a water source; the outlet is connected with a data collection and processing system for measuring the soil mass corrosion resistance; an included angle is formed between the soil sample box in the length direction and the horizontal surface of the base; the position of the inlet is higher than that of the outlet; the soil sample box comprises a soil sample chamber for placing a soil sample; the soil sample chamber is communicated with the inlet and the outlet; a rainfall frame is arranged at the upper end of the soil sample chamber; the rainfall frame is fixed on the base through a pipeline; the pipeline is connected with the water source; a plurality of spray heads communicated with the pipeline are arranged on the rainfall frame; the spray heads are 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...
