      (一)注重前期的准备工作。给排水的管线管根据专业分为:生活/生产给水管、消防给水管、废水管、污水管等,生活给水管还可以细分为高区和低区给水。各种给水管的专业不同,设计和施工部门也就不同,要在有限的城市空间中减少各类的关系碰撞,必须对前期的管线规划工作进行合理的布置和详细的设计,使各类管线按各自的设计位置敷设,避免后期施工的混乱和返工现象。

      (六)沉降因素的考虑。城市排水管线的敷设中,有些地方会出现沉降的情况,为了保证管线的安全,不仅要按规定的设计方法、标准进行,还要考虑沉降因素的情况处置。例如,某城市地势平缓,中间有条从北向南的大河,经过现场的考察,施工地容易出现沉降情况,最大值可能达到250mm,当管线穿过隔堤,容易造成破口,所以必须大量减少管线穿过隔堤的数量。为了减少沉降差异,可以在管道的隔堤上下游设置伸缩量为300mm的柔性接口;为了防止沉降情况出现的倒流,可以在第一个检查井设置300mm的跌水,过渡段设置短管衔接;为了清淤可以设置沉泥井。管材和接口尽量选择柔性管材材料,给水管道和消防管道使用HDPE复合管,排水管使用UPVC管。
