Abstract

The invention relates to a side slope testing device for simulating rainfall space time changes. The side slope testing device for simulating rainfall space time changes comprises a rainfall simulating unit, a test platform unit and a data acquisition analyzing unit. The rainfall simulating unit comprises a rainfall loop formed by a water tank, a water pressure pressurizing part, a plurality of electromagnetic valves and a plurality of nozzles which communicate through a water pipe. The water pressure pressurizing part is arranged on a pipeline of the rainfall loop, and the data acquisition analyzing unit separately controls the closing magnitude of the electromagnetic valves to control the drainage flow strength on different pipelines, so that time and space distribution of rainfall is simulated. The side slope testing device for simulating rainfall space time changes, provided by the invention, is simple to operate and has the characteristics of high automatic degree of data acquisition and high repeatability.

Description

technical field [0001] The invention relates to the field of soil water environment test, and in particular relates to a slope test device for simulating temporal and spatial changes of rainfall. Background technique [0002] Due to the complex and diverse components of municipal solid waste, it is difficult to deal with and utilize them. At present, the garbage disposal methods mainly include sanitary landfill, composting and incineration, and sanitary landfill is the main method. And many sanitary landfills are facing closure. Therefore, it is of great significance to study the composition of the capping layer of municipal solid waste landfills. It is currently believed that soil cover has better durability than composite cover, is more adaptable to harsh weather conditions, and is more economical. And the soil covering layer has a certain slope, which is also the problem to be solved by the present invention. [0003] At present, theoretical analysis and numerical simu...
