Description

Technical Field

[0001] The utility model relates to the technical field of highway design, in particular to a roadbed water flow scouring simulation experimental research device for highway design. Background Art

[0002] Scour and water damage is a common failure mode in roadbed engineering. With the continuous expansion of domestic engineering construction sites, erosion and water damage problems have become increasingly prominent. It has now become a hot topic of concern in roadbed engineering in the fields of highways, railways, water conservancy, etc. At present, domestic research methods and devices for roadbed erosion mainly focus on two aspects. The first emphasizes the impact of rainfall on roadbed erosion. This type of utility model mainly simulates different rainfall amounts, rainfall intensities, and rainwater to qualitatively analyze the impact of rainfall on the changes in the surface morphology of the roadbed and the impact on the moisture content and mechanical properties of the filler soil, and attempts to establish a quantitative relationship between rainfall and the degree of roadbed erosion. In fact, for most engineering roadbeds, the catchment area behind the slope exceeds the slope surface. The overwash formed by the convergence of rainfall behind the slope is the most important influencing factor of roadbed surface erosion and destruction. For rainfall, the splashing effect of raindrops will cause different degrees of crusting of the surface soil of the roadbed, which will make the soil pores smaller. The reduction of seepage and the advancement of runoff generation time have increased the complexity of the study on water flow and roadbed erosion. At the same time, the simulation of rainfall is difficult to match the actual environment on site. The height of rainfall, the density of raindrops, and the change of rainfall intensity during rainfall cannot be realized in the simulation, which hinders the further in-depth development of roadbed erosion research. The second study is the effect of runoff on roadbed erosion. This type of utility model adopts the method of applying a beam of water flow at the top of the slope to erode the roadbed. It can quantitatively analyze the influence of water flow rate and flow velocity on the amount of sand washed on the roadbed and the depth of gullies. However, in actual roadbed projects, rainwater will first converge behind the slope. The scouring water flow initially proceeds in the form of overflow, and gradually erodes to form gullies or shallow gully runoff over time. At the same time, the effect of seepage on roadbed erosion and stability cannot be ignored. In engineering, it is often necessary to control the amount of seepage to maintain the stability of the roadbed, but the seepage on the slope surface is not considered in this type of device.

[0003] In the prior art, the roadbed water flow flushing device is used because the materials used for roadbed simulation are mostly mud and sand. Therefore, after being flushed by water flow, the mud and sand will block the pipeline of the simulation device, so it needs to be improved. Utility Model Content
