摘要
针对聚乙烯塑料管(PE管)埋设于地下用于消防供水时,对其承载变形与土壤重量与地面产生的静负载、运输车辆经过时产生的动负载、管材结构性能和周围土壤结构性能的关系进行了分析,介绍了PE埋地管变形的计算方法和评定标准。
External forces caused by earth and heave vehicle on PE pipe for underground fire protection services are investigated and analyzed. The Spangler Equation is introduced to calculate the pipe deflection. The sufficient pipe stiffness to remain intact and not leak when exposed to external forces is evaluated on acceptable deflection which is not exceed 5 percent of the inside diameter of the pipe.
