Abstract

Disclosed herein is a hydroplaning debris-flow simulation apparatus which includes an inclined flume provided with a plurality of water permeation units.

First claim

What is claimed is:

1. A hydroplaning debris-flow simulation apparatus, comprising an inclined flume,
a debris supply unit disposed above the inclined flume wherein the debris supply unit stores debris therein and supplies debris into the flume;
a gate located between the debris supply unit and the flume that is operated to control the amount of debris supplied to the flume;
the flume comprising a plurality of water permeation units,
wherein the plurality of water permeation units are provided in the bottom and opposite sidewalls of the flume,
wherein the water permeation units are provided in each of the flumes at positions spaced apart from each other in a longitudinal direction of the flume,
wherein each of the water permeation units comprises a porous plate or a hollow plate, and
wherein water supply control valves are respectively connected to parts of the water permeation units that are provided on the bottom and opposite sidewalls of the flume so that amount of water that is supplied into each part of the water permeation unit can be controlled by the water supply control valves wherein the water mixes with the debris supplied to the flume to simulate a wet ground surface.

2. The hydroplaning debris-flow simulation apparatus as set forth in claim 1 , wherein the flume comprises a plurality of flumes arranged at positions spaced apart from each other at regular intervals or parallel to each other.

3. The hydroplaning debris-flow simulation apparatus as set forth in claim 2 , wherein the flumes respectively comprise a plurality of gates provided at different positions in the flumes, each of the gates controlling discharge of debris-flow.

4. The hydroplaning debris-flow simulation apparatus as set forth in claim 3 , wherein each of the flumes comprises
a water-pressure gauge or a load cell provided on each of an upper portion, a medial portion and a lower portion of a bottom of the flume, the water-pressure gauge measuring a water pressure in the flume, the load cell measuring a load of the debris-flow.

5. The hydroplaning debris-flow simulation apparatus as set forth in claim 3 , wherein the water permeation units are provided in each of the flumes at positions spaced apart from each other in a longitudinal direction of the flume.

6. The hydroplaning debris-flow simulation apparatus as set forth in claim 3 , further comprising
a water supply pump coupled to the water permeation units, the water supply pump supplying water to the water permeation units so that the water is drawn into the flume.

7. The hydroplaning debris-flow simulation apparatus as set forth in claim 3 , wherein each of the water permeation units comprises a porous plate or a hollow plate that supplies water into the flume only through a predetermined open portion, and
the water permeation units have a same structure and are provided in at least one of the flumes.

8. The hydroplaning debris-flow simulation apparatus as set forth in claim 3 , wherein each of the water permeation units comprises a porous plate or hollow plate that supplies water into the flume only through a predetermined open portion, and
the water permeation units having different structures are combined in at least one of the flumes.
