Test device and method for simulating the effect of spur dike on water flow

Abstract

The invention discloses a test device and method for simulating the effect of a spur dike on the water flow, and belongs to the field of physical mechanic model tests. The test device is composed of a test module, a light source module, a data collection module and a control module; the test module is composed of foundation test components of the spur dike water flow test; the light source module and the data collection module are attached to the test module; the control module controls other modules of the device; an integrated device is adopted, the particle picture speed measuring technology is designed and introduced for finishing the spur dike water flow test process, and the beneficial effects of being less in manpower consumption, high in efficiency, low in test cost, energy-saving, environment-friendly, suitable for the wider station range, high in test precision and the like are achieved.

Description

technical field [0001] The invention relates to the field of hydraulic physical model tests, in particular to a physical model test device and method for simulating the action of spur dikes on water flow. Background technique [0002] In the field of waterway regulation, setting spur dikes on both sides of the river regulation section according to the river regulation requirements is a very effective river regulation engineering technical solution. Among them, the spur dam is a hydraulic structure widely used in waterway improvement projects. It mainly plays the role of narrowing the river bed, guiding water to the channel, adjusting the direction of water flow, changing the velocity of water flow, scouring shoals, and guiding sediment. Therefore, spur dikes are widely used in domestic and foreign river regulation projects: in the deep water channel regulation project of the Yangtze River Estuary, a group of spur dikes is set up correspondingly for converging water into the ...

AI Technical Summary

Problems solved by technology

[0004] Among the published technical schemes for spur test, most of spur flow tests rely on temporarily constructed water tanks, which have the disadvantages of many instruments required for the test, complicated test steps, large space occupation during the test, and excessive manpower consumption during the test. At the same time, there is still a lack of technical schemes for spur dike tests that are highly professional, easy to operate, and can significantly reveal the hydraulic characteristics of each section under the action of spur dikes; Insufficient display of the flow velocity distribution of the water flow section under the disturbance of the spur dike, and the demonstration effect is not obvious, etc.
