Embodiment
Referring to Fig. 1, Fig. 5, one kind simulation current under the conditions of sunshine, rainfall and slacking wash away to reservoir stability rock mass
The device of effect includes test cabin 1 and the spiral agitator axle 4 being located in the test cabin, and test cabin 1 is preferably barrel-shaped,
Spiral agitator axle 4 is provided with spiral agitator blade 5, and spiral agitator axle 4 is connected with the motor 6 outside test cabin 1, electricity
Motivation 6, which is rotated, drives agitator rotation to be that the water in test cabin 1 is produced along container inner wall mobilization dynamic, along the circumference of test cabin 1 week
Four rock sample containers 2 are respectively equipped with the long quartering, the edge of rock sample container 2 connects with the side edge of test cabin 1 and with test cabin 1
It is logical.The inwall of rock sample container 2 is provided with sealant, such as Fig. 4 is provided with qi of chong channel ascending adversely pad 13 between the inwall of rock sample container 2 and sealant, punching
Air cushion 13 is connected with high-pressure air source, and souring of the different flow rate of water flow to rock sample is simulated with this, thus realize part rock sample by
To current scour, by storehouse bank rock mass state (the only local rock in reality of current scour under more real simulating natural condition
Stone is washed away by current).
During work, rock sample 3 is placed in the rock sample container 2, and the side surface portion of rock sample 3 is placed in rock sample container, part
It is exposed in test cabin 1, when the spiral agitator axle 4 in test cabin 1 drives spiral agitator blade 5 to rotate, makes test cabin water
