Abstract
The invention discloses an experiment device and method for a scouring plane effect on an underwater material. The experiment device comprises an outer water tank, a base connected to the bottom of the outer water tank and a monitoring component arranged at the upper part of the top of the outer water tank, wherein the outer water tank is used for bearing fluid containing tracer particles; bearingcomponents are arranged on a tank wall of the outer water tank and can be completely or partially immersed into the fluid; an inner rotating cylinder is arranged in the outer water tank; a power device is arranged in the base and is in transmission connection with the inner rotating cylinder; the monitoring component comprises a supporting component, capture components suspended on the supportingcomponent and developing components arranged in the inner rotating cylinder; and the developing components are connected to the supporting component through a guide rod. Through the application of the experiment device and the experiment method, scouring is generated through the inner rotating cylinder in an autorotation manner, the erosion acting force is lasting and stable and is suitable for long-period experiments, and furthermore, a water circulation system does not need to be provided, so that the experiment device is more energy-saving.
Description
technical field [0001] The invention relates to the field of material testing, in particular to an experimental device and method for an underwater material scouring plane effect. Background technique [0002] In the field of hydraulic structures, especially in dams, embankments, bridges and other wading structures, since part of the structure of the building is in the underwater position for a long time, it is inevitable that the long-term erosion and erosion of the building by the water flow will be formed, resulting in The characteristics of the material on the surface of the object change, and even affect key physical indicators such as elastic modulus and linear expansion coefficient. At present, researchers' understanding of fluid flow state and erosion characteristics is still at a very macroscopic stage, and there is no quantitative analysis device that can be used for theoretical basis and microscopic characteristics. Contents of the invention [0003] In view of...
