Abstract
The invention discloses an experimental device and method for underwater material scouring plane effect, comprising: an outer water tank, a base connected to the bottom of the outer water tank, and a monitoring component arranged above the top of the outer water tank; Carrying fluid containing tracer particles, the groove wall of the outer water tank is provided with a bearing member, the bearing member can be partially or completely submerged in the fluid, and an inner drum is arranged in the outer water tank; the base A power device is arranged inside, and the power device is drivingly connected with the inner drum; the monitoring assembly includes a support member, a capture member suspended on the support member, and an imaging member disposed in the inner drum , the developing member is connected with the supporting member through a guide rod. By applying the technical solution of the present application, scouring is generated by the self-rotation of the inner drum, and the erosion force is lasting and stable, which is suitable for long-term experiments, and the device does not need to provide a water circulation system, which 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 the scouring plane effect of underwater materials. Background technique [0002] In the field of hydraulic structures, especially in wading structures such as dams, embankments, bridges, etc., 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 lead to the construction of the building. The characteristics of the surface material change, and even affect key physical indicators such as elastic modulus and linear expansion coefficient. At present, the researchers' understanding of the erosion characteristics of the fluid flow is still at a very macroscopic stage, and there is no quantitative analysis device that can be used for theoretical basis and microscopic characteristics. SUMMARY OF THE INVENTION [0003] ...
