摘要: 通过对消防围堵用围堤受力进行分析,建立了围堤设置参数的计算模型,提出聚氨酯围堤使用时围堤能阻挡流体的高度与其厚度呈正比关系,阻燃聚氨酯与水泥结合后,能承受的水平拉力与其厚度的二次方成正比。以改性阻燃聚氨酯为围堵材料,通过试验确定了计算模型的参数,并对计算模型的误差进行了确定。

Abstract: This paper analyzes the force acting on containment dikes used in firefighting spill control and establishes a calculation model for dike setup parameters. It proposes that the height of fluid that a polyurethane dike can block during use is directly proportional to its thickness. When flame-retardant polyurethane is combined with cement, the horizontal tensile force it can withstand is proportional to the square of its thickness. Using modified flame-retardant polyurethane as the containment material, the parameters of the calculation model are determined through experiments, and the error of the model is assessed.
