Earth pillar imitation experiment device aiming at reclamation soil and coal ash matrix in mining area

Abstract

The utility model discloses an earth pillar imitation experiment device aiming at reclamation soil and a coal ash matrix in a mining area. The earth pillar imitation experiment device aiming at the reclamation soil and the coal ash matrix in the mining area comprises a transparent pillar body, a movable plate, a stainless steel wire gauze net, a chassis, a support frame and an underwater level imitation component, wherein the chassis is fixed at one end of the pillar body, the support frame is connected with the chassis, the lateral wall of the pillar body is provided with a row of water potential sensor installation holes, a row of salt content sensor installation holes, a row of temperature sensor installation holes, two rows of air vents and a row of sampling holes, the movable plate and the stainless steel wire gauze net are both contained inside the pillar body, and the underwater level imitation component is connected with the bottom of the chassis. The earth pillar imitation experiment device aiming at the reclamation soil and the coal ash matrix in the mining area has the advantages of completing the experiments such as capillary water rise, imitation of soil water and salt movement imitation under the condition of atmospheric precipitation, imitation of soil water and salt movement imitation under the condition of evaporation, soil water and salt movement imitation under the condition of controlling the variation of underwater level, achieving the dynamic monitoring of the water slat movement state in the coal-ash-filled reclamation soil and the coal ash matrix in the mining area, and figuring out a reclamation mode most suitable for the growth of crops.
