全风向梯度集沙仪的研制

Research and Development of Gradient Sand Sampler for All Wind Direction

兰新铁路风区防风沙工程的建设对保证列车风区安全行驶至关重要,而掌握风沙流规律是防沙工程设计的基础,为此,根据历史大风特征统计分析结果研制了全风向梯度集沙仪,对风沙流进行现场观测。全风向梯度集沙仪为兰新铁路第二双线防沙减灾工程的建设提供了基础数据依据。

It is vital that the sand prevention engineering ensures the operation safety in the wind area along Lanzhou-Xinjiang railway, and the wind sand flow rules is the base for designing the sand prevention engineering. According to the characteristics of historical wind data, the sand sampler for all wind direction is developed to measure the saint flow. The gradient sand sampler for all wind direction will provide the basic data for sand prevention engineering of the second Lanzbou-Xinjiang double lines.
