Abstract

The invention relates to the technical field of artificial rainfall simulation, in particular to a side slope rainfall device with controllable horizontal space variability and a method thereof. The device comprises a water supply system, a filter system, a water delivery system, a rainfall system and a voltage control system for controlling rainfall of raindrop nozzles, the rainfall system comprises a rainfall tray and a plurality of raindrop nozzles, the water supply system is communicated to the rainfall tray through the water delivery system, and the filter system is arranged at a water outlet of the water supply system. The aperture of a filter screen of the filter system is smaller than or equal to the aperture of the raindrop nozzles, the rainfall disc is located above the slope test box to be tested, the raindrop nozzles are connected to the rainfall disc, piezoelectric deformation elements are arranged on the raindrop nozzles, and the piezoelectric deformation elements of the raindrop nozzles are connected with the voltage control system. And the voltage control system controls the raindrop nozzle to spray raindrops with different frequencies and sizes in the horizontal direction. According to the invention, different positions have different raindrop frequencies and sizes, and specific variability requirements are met.
