River evolution experimental facility

Abstract

The invention discloses a river evolution experimental facility. A seepage separating slot is formed in the central position of a water tank, the front end of the seepage separating slot is provided with a water inlet front pond communicated with the seepage separating slot, the water inlet end of a water inlet pipe is connected to a water supply tank, and the water outlet end of the water inlet pipe extend into the water inlet front pond. A seepage outflow channel is arranged at the rear end of the water tank, a river outflow channel is arranged at the rear end of the seepage separating slot, and the seepage outflow channel is arranged under the river outflow channel. A desilting rinsing bucket is arranged under an outlet of the river outflow channel, and a water collecting tank is arranged under the seepage outflow channel. The lower portion of the water collecting tank is connected with a drain chamber through a circulation line. The front end of the bottom of the water tank is connected with the front end of a second support in a hinged mode, and a slope adjusting device is arranged at the rear end of the water tank. A blower, a spray thrower, an illuminator tube, and an image collector are arranged in an experiment shed on the top of the water tank. The river evolution experimental facility has the beneficial effects of being capable of adjusting slope, simulating illumination, dropping water, blowing wind and recycling utilizing simulating water.

Description

technical field [0001] The invention belongs to a hydraulic engineering experimental device, in particular to a slope-adjusted river evolution experimental device that can simulate illumination, precipitation and wind. Background technique [0002] Indoor model experiment is a commonly used technical means to study practical water conservancy engineering problems, especially in river evolution simulation in recent years. The natural model experiment method is a basic method to study the development of rivers, which can generalize and simulate the long-term evolution process of natural rivers in a short period of time. There are various forms of natural rivers. It is important to use artificially shaped rivers to simulate the dynamic process and laws of the evolution and development of curved, branched and wandering rivers in nature, and to study the influence of different water, sediment and riparian boundary conditions on the evolution and development. Theoretical value, b...

AI Technical Summary

Problems solved by technology

Existing studies on the evolution and development of rivers have achieved many results, but there are three deficiencies: First, most of the models are built indoors, and the scale of the devices is large and heavy. The area is large and the flexibility is small; the second is that the influence of seepage loss is not fully considered

At present, the research on river channel seepage is mostly limited to regional statistical analysis, and there are still few studies on seepage characteristics and laws in the process of river evolution, which need to be considered and calculated in detail in the theoretical model and experimental process; third, for traditional river engineering model experiments , the adjustment of the slope of the river is manual excavation, which is time-consuming and labor-intensive
