摘要
针对浙江沿海某成品油输油管道站场站外埋地管线受到侧向和轴向推力,且管线两侧均无法移动,导致站内管线应力集中,造成部分管线位移的问题,采取了站内外管线上方降低荷载、站内管线更换可调节管托、固定墩增加混凝土方桩支护、站外管线平衡压带更换配重块等措施,释放了管线应力,保证了管线的安全运行。
The buried pipeline outside an oil product pipeline station in Zhejiang coastal area is subject to lateral and axial thrust,and both sides of the pipeline cannot move,resulting in stress concentration and displacement of some pipelines.In order to solve the problem,the measures,such as reducing the load above the pipelines inside and outside the station,replacing the adjustable pipe bracket for the pipelines inside the station,increasing the concrete square pile support for the fixed pier,and replacing the counterweight with the balance pressure belt for the pipelines outside the station,are taken to release the pipeline stress and ensure the safe operation of the pipelines.
