Problems solved by technology
However, in this patent, the water flow is controlled to flow in the pipeline and scour the test piece. Due to the constraints of the shape of the pipeline and the acceleration of the booster pump, the water flow is greatly interfered by unnatural factors, which cannot better simulate the natural field. , such as streams or ditches and other types of natural water flow conditions to achieve research

The invention discloses a test system for simulating the scouring erosion effect of water flow on a test piece, the test system comprises a first water tank used for containing test water and a water outlet arranged on one side of the first water tank, the test system is characterized in that a water outlet groove component is arranged at the water outlet of the first water tank in an obliquely downward connecting manner; a second water tank is connected below the water outlet groove component, a test piece installation groove is formed in the groove bottom face of the lower portion of the water outlet groove component, a water outlet control mechanism capable of controlling the water outlet condition of the first water tank is further arranged, and a temperature control device is further arranged and used for controlling the water temperature for testing. According to the invention, the natural flowing condition of water flow can be better simulated to carry out a water flow scouring test, so that the scouring effect of a natural flowing water body on a tested test piece can be better studied, and the test system has more generalized applicability.
Description
technical field [0001] The invention relates to the technical field of water erosion research, in particular to a test system for simulating the erosion and erosion effect of water flow on a test piece. Background technique [0002] The erosive action of water flow is often responsible for the formation and diversion of river and stream beds. River water not only has an obvious scouring effect on soil riverbeds, but also on some rocks with low hardness, such as sandstone. Limestone, etc. also have a great erosion effect. Therefore, in order to study the scouring and erosion effect of water flow on rocks, it is necessary to do water scouring experiments. In addition, in some artificial water conservancy projects such as ditches, spillways and other water conservancy buildings, it is also necessary to pass the water scouring test to study the effect of water scouring and erosion to provide a theoretical basis for construction guidance. [0003] Existing water scouring test ...
