AN APPARATUS FOR RAINFALL SIMULATION IN CENTRIFUGAL MODEL TEST

摘要

The present invention relates to a raining apparatus for a rainfall simulation in a centrifugal model test, which, for measuring displacement occurring in a model ground structure when it rains, installs the model ground structure on a soil tank installed on a centrifugal unit, makes the model ground structure rotates at a high speed, and provides rain artificially for the model ground structure. In particular, the raining apparatus of the present invention comprises: a first bracket and a second bracket to be installed a certain distance on the top end of the soil tank; a first rainwater spray pipe installed on the first bracket to be able to rotate with a number of nozzles installed at a certain interval; a second rainwater spray pipe installed on the second bracket to be able to rotate with a number of nozzles installed at a certain interval; a water tank with water stored inside; a compressor for giving pressure to the inside of the water tank and supplying the water stored inside to the first rainwater spray pipe and the second rainwater spray pipe; and a measuring cup placed on the surface of the model ground structure, in which the water discharged through the first rainwater spray pipe and the second rainwater spray pipe is stored. The raining apparatus of the present invention can accurately and easily measure what impact water (rainwater) has on an actual ground structure in an experimental way.
