摘要
结合工程实例,对公称管径≥500 mm的大管径直埋热水管道的安装方式、设计理论及设计要点进行了探讨,对大管径直埋热水管道的设计、施工提出了建议。只要满足强度和稳定性条件,应优先采用无补偿冷安装方式。在设计时应重点考虑防止局部失稳、加强管件结构及控制管道坡度变化幅度。
The installation mode, design theory and design essentials of directly buried hot-water pipeline with nominal diameter of equal to or greater than 500 mm are discussed, and suggestions on the design and installation of directly buried hot-water pipeline with large diameter are offered. The cool installation mode without expansion should be adopted preferably provided that the conditions of strength and stability are met. Preventing local instability, reinforcing pipeline structure and controlling change amplitude of pipeline slope should be considered importantly in the design.
