Abstract

The invention discloses a rain-intensity-controllable unsaturated soil infiltration simulation system which comprises a test bench with pulleys at the bottom part; a water supply tank, an overflow water tank and a model tank are arranged on the test bench, the model tank is a top-opening round bucket, a plurality of separators respectively with a reserved hole at the center are arranged inside the model tank, a drain valve is arranged at the bottom of the model tank, a water supply pump is arranged in the water supply tank, the water supply pump is connected to the overflow water tank by a water supply pipe, the overflow water tank is connected to the water supply tank with an overflow water pipe, a raindrop generator is connected to the bottom of the water supply tank, the raindrop generator includes a guide pipe, a regulating valve, a syringe needle and a dead plate, a funnel is fixed on the lower surface of the dead plate, and a discharge hole of the funnel is arranged above an opening of the top of the model tank; to the rain-intensity-controllable unsaturated soil infiltration simulation system performs point-to-point control through the raindrop generator, and is accurate in rainfall and high in test precision.

Description

technical field [0001] The invention relates to an unsaturated soil rainwater infiltration simulation system, in particular to an unsaturated soil rainwater infiltration simulation system with controllable rain intensity. Background technique [0002] Soil is a common porous medium in engineering, and its permeability is an important property, while the common soil in geotechnical engineering is mainly unsaturated soil, so the research on unsaturated soil has attracted the attention of researchers at home and abroad, and the permeability law is An important research content. The rainfall simulation device in the existing soil infiltration simulation device often uses the way of main pipe and branch pipe to supply water, or sprays in the way of shower, which has high difficulty and imprecise control of rainfall intensity, especially in the case of uneven rainfall under the condition of light rain intensity , Rainfall test accuracy is low. Contents of the invention [0003...
