给出了管道伸缩量及轴向力的计算公式,对比分析了固定支(吊)架+导向活动支(吊)架+补偿器方式与固定支(吊)架+导向活动支(吊)架+自然补偿等常见方式的优缺点。提出了轴向、横向滑动支(吊)架方式,管道可在支(吊)架限定范围内自由滑动,该方式已在多个工程中成功应用,并取得良好的使用效果。
The calculation formulas of the telescopic amount and the axial force of the pipeline are given, and the comparison between the way of the fixed support (crane) + the guide movable support (crane) + compensator and the fixed support (crane) + guide movable support + Natural compensation and other common ways the advantages and disadvantages. The axial and transverse sliding support system is proposed. The pipeline can slide freely within the limits of the support system. This method has been successfully applied in many projects and has achieved good results.
