Technical field
The utility model profit relates to a kind of mountain torrents STUDY OF DEBRIS FLOW technology, is mainly used to measure nature raceway groove and water trough model test debris flow slurry flow velocity.
Background technology
Mountain torrents rubble flow worldwide extensive development.In China, mountain torrents rubble flow is also one of main geologic hazard type.For the comparatively systematic research of rubble flow, China starts from last world sixties.STUDY OF DEBRIS FLOW develops into today, no matter is the rubble flow that nature breaks out, or the debris flow slurry of flume test, and debris flow velocity is all important indicators for research rubble flow.
Add up existing debris flow velocity measurement method and technological means, roughly have the several methods such as leading fluid-velocity survey method, buoy method, laser velocimetry, strain gauge method, hydrometry.Tap fluid-velocity survey method can only measure the flow velocity of rubble flow tap, truly can not reflect the change of the omnidistance flow velocity of a battle array time rubble flow.Buoy rule can only measure the surface velocity of debris flow body, and when the Material texture chosen kicks the beam, buoy float is subject to the impact of fluidised form; When material is overweight, buoy float, from startup to synchronized with slurry, needs the regular hour.The material of laser velocimetry to test has higher requirement, generally need to reject sticky particle part, and the unit weight of slurry is generally unsuitable for more than 1.5t/m
3.Strain gauge rule needs placement sensor, when the too little meeting of range of inductor by inductor impact damage, if inductor range is too large, is difficult to the flow velocity accurately measuring slurry because peak value is too large.Hydrometry is when measuring slurry flow with electronic scale, and the data recorded often comprise the kinetic energy data of slurry; When accessing with the timing of basin device, then more loaded down with trivial details and labor capacity is larger.
