Abstract

The invention discloses an artificial rainfall simulation device for debris flow testing. The pressure of a water tank can be flexibly adjusted conveniently through the device, corresponding pressurecan be set according to the underlying conditions and rainfall characteristics of an area, so as to further control the rainfall type; the concentration phenomenon of area point rainstorm can be simulated through regulating the internal pressure of sub water tanks; through closing one or more of the sub water tanks, and the rainfall process under windy weather can be simulated, and the rainstorm type can be simulated through overlapping the rainfall area; the rainfall data can be input through a computer system, the rainfall type can be accurately and rapidly controlled by controlling a pressure control valve through a controller; and the pressure control valve can be used for well filtering solid particles, phytoplankton and the like in river water, so that the energy conservation and environment protection can be achieved, and the service life of a nozzle can be prolonged.

Description

technical field [0001] The invention relates to the technical field of debris flow start-up tests, in particular to an artificial rainfall simulation device for debris flow tests. Background technique [0002] Debris flow is a solid-liquid two-phase fluid filled with a large amount of sand, stones and boulders. It has the characteristics of sudden outbreak, strong handling impact and silting ability, and has great destructive power. The nature of debris flow determines that its formation requires sufficient water sources. The water source that causes debris flows in my country mainly comes from heavy rain, which manifests itself as a disaster when the rainfall reaches a certain critical rainfall value. Therefore, the determination of critical rainfall is of great significance for studying the formation mechanism of debris flow, analyzing and predicting the characteristics of future activities of debris flow, and guiding the design of debris flow prevention and control proje...
