The invention provides an experiment device for carbonate rock corrosion speed under a karst-region soil environment, aims to solve the problems that current corrosion experiments under the soil environment can only measure the corrosion test piece weight loss, detection data is single, and sufficient data support cannot be provided for corrosion researches, and belongs to the field of corrosion researches. The experiment device comprises a tank with an upper-end opening, a water guide pipeline and an air guide pipeline, wherein a draining hole is formed in the bottom of the tank, fiber cloth or a multilayer screen is laid at the upper-end opening of the tank, a water receiving tank is arranged at the bottom of the tank, one end of the water guide pipeline is communicated with the bottom of the water receiving tank, and one end of the air guide pipeline is communicated with the tank lateral wall above the water receiving tank.
Description
technical field [0001] The invention relates to a dissolution rate experiment device, which belongs to the field of soil dissolution research. Background technique [0002] The dissolution test piece method is one of the methods to quantitatively evaluate karstification and its carbon sink strength. It is to place uniformly prepared standard carbonate rock test pieces in the air, on the soil surface and at different depths of the soil for a certain period of time (usually a hydrological year). Then take it out and weigh it, and indirectly calculate the strength of the karst carbon sink at the place where the test piece is buried according to the reduction of the test piece. This method is widely used in the study of karst carbon sink. On the surface or buried in the soil at different depths, the final measurement result is only the weight loss of a single dissolution test piece, lacking the collection and research of relevant data in the soil environment.
