Abstract

The invention discloses a sand laying device for model test sediment starting research. The sand laying device comprises a sand containing groove used for containing model sand, an observation plate connected with the top of the sand containing groove, a partition plate embedded in the middle of the sand containing groove, a glass plate covering the top of the sand containing groove, and a concentric-square-shaped water filtering sponge ring surrounding the sand containing groove by one circle. By utilizing the technical scheme provided by the embodiment of the invention, sediment starting experiment research can be carried out on model sand with different properties, the sand paving form and the observation definition after starting are ensured, the test can be smoothly carried out, and the sediment starting flow velocity result is more accurate and reliable.

Description

technical field [0001] The present application relates to the field of water conservancy experiments, in particular to a sand spreading device used for model test sediment start-up research. Background technique [0002] In the field of water conservancy experiments, the sediment tank physical model test is a common research method. The sediment tank model test analyzes the flow and sediment movement in the laboratory according to the river dynamics theory. Simulate the scour and silt near hydraulic structures, and provide technical reference for actual project planning, design, evaluation, etc. [0003] The study of sediment erosion and deposition in the test involves the selection of model sand. Because there are certain differences in the color and material of different model sands, mastering the properties of model sands is directly related to the accuracy of model tests. Among them, the starting flow velocity of model sand is the main factor in the selection of model ...
