The invention discloses an indoor analog experiment device for roadbed slope
erosion. The indoor analog experiment device comprises a movable liftable slope
analog device and an artificial rainfall
analog device, wherein the movable liftable slope
analog device comprises a base device, a panel groove device and a
slope gradient adjusting device, the base device and the panel groove device are connected together through a movable hinge, and the panel groove device can rotate freely around the hinge; the artificial rainfall analog device comprises a
water supply device, a support device and a spraying device, the
water supply device comprises a
water supply pool, a
water pipe, a water pump, an adjusting valve, a
branch valve and a hydrometric
propeller, the support device comprises movable wheels, an expansion bracket, a transverse support rod and a longitudinal support rod, and the spraying device comprises a water guide
pipe and a prayer head. According to the indoor analog experiment device, a large amount of roadbed slope
erosion data is obtained under different working conditions and different rainfall conditions within a short period of time. The indoor analog experiment device is simple in structure, convenient to operate, safe and reliable, low in cost and high in efficiency, and is convenient to popularize and apply.
