The invention relates to a device for testing ecological slope protection of ecologic rock and
soil mechanics under
simulated rainfall condition, which is mainly used for studying scouring (or
erosion) characteristics test of rock and soil slope by artificial rainfall and belongs to the field of
geotechnical engineering and
environmental engineering. The test device comprises an
automatic variable slope test rack, a test soil bin and a
rainfall simulator with adjustable
rain intensity, wherein a rotary support is composed of a guide rail, a
crank, a
crank brake, an upper shaft and a device for preventing backward sliding; a
fixed bearing support is composed of a lower shaft, a bearing seat, a bending guide groove, a
capstan and a lower shaft caging device; the
rainfall simulator with adjustable
rain intensity is disposed on the variable slope test race through a support and includes a
rainfall simulator, a
pressure sensor, a vibrator, a
barometer, a
relief valve, etc. The inventive test device has the advantages of simple structure, adjustable
rain intensity, uniform rainfall, automatic online collection of air pressure,
water pressure and rainfall amount of the rainfall simulator and reduced time and labor force for loading the test soil bin.
