在对城市热力管网进行设计的过程当中,当管道覆土的深度过浅的时候,那么就会影响到管道竖向的稳定问题,从而导致管道局部发生凸出的问题,甚至严重的时候会供出地面的情况;而当管道覆土过深的时候,那么就会致使管道外的护管表面的实际的温度不断的升高,甚至会超过要求的温度范围,为了能够确保外表面的温度保持正常的状态,一定要合理的、科学的增加管道保温层的厚度问题,这就在一定程度上增加了工程材料的支出。此外,如果管道覆土的深度过深的时候,就会致使沟槽挖方工作量有很大的增加,这就大大的增加了施工的难度以及工程造价,这也在一定程度上埋下了安全问题。所以,合理的、科学的进行设计管道的埋深是现阶段设计人员一定要加强重视的内容,希望本篇文章能够对相关的工作人员或者是单位提供一定的帮助。
In the process of designing the heat pipe network in urban areas, when the depth of soil covering pipelines is too shallow, then the vertical stability of the pipelines will be affected, causing the pipelines to protrude locally, even in severe cases The situation on the ground; and when the pipe over the soil when too deep, then it will lead to the pipe outside the pipe surface of the actual temperature continues to rise, or even exceed the required temperature range, in order to be able to ensure the temperature of the outer surface to maintain normal State, we must be reasonable and scientific to increase the thickness of pipe insulation, which to some extent, an increase of expenditures on construction materials. In addition, if the depth of pipe overburden too deep, it will lead to a significant increase in the workload of the trench excavation, which greatly increased the difficulty of construction and project cost, which also to some extent laid the security issues . Therefore, reasonable and scientific design pipeline depth is the designer at this stage must pay more attention to the content, I hope this article to the relevant staff or units to provide some help.
