Abstract
The invention discloses an experiment device for simulating flow and scouring around a pipeline and an experiment method. The experiment device for simulating flow and scouring around the pipeline comprises a riverbed model, a circulating mechanism, a pipeline mechanism and an observation mechanism. According to the experiment device for simulating flow and scouring around the pipeline, the flow can be controlled by selecting different riverbed media to simulate different riverbed types, changing the laying mode of the pipeline and adjusting the power of a water pump according to experiment requirements, and the law of flow and scouring around the pipeline is studied by changing three control factors of the model. The whole experiment device is a closed system, and the water consumption ofthe experiment is reduced on the premise that the experiment effect is met, so that experiment implementation is more environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of pipeline water damage model experiments, in particular to an experimental device and an experimental method for simulating flow around a pipeline and its erosion. Background technique [0002] With the rapid development of domestic pipeline projects, the mileage of various pipelines has increased rapidly, such as water supply pipelines, drainage pipelines, gas pipelines, heat pipelines, and long-distance oil and gas pipelines. At present, various pipelines are widely distributed, and the geological conditions along the line are complex, and some geological disasters will inevitably occur, which will affect the safe operation of pipelines. [0003] Geological disasters are increasingly harmful to the safe operation of pipelines, accounting for about 12%-20% of the accident rate during operation according to statistics, and geological disasters caused by "water" are very common along pipelines. [0004] In...
