- 福建某项目埋地高密度聚乙烯管道,在一次台风过后出现了浮起及管道变形现象,采用地基加固和管沟回填等措施后,有效地控制了高密度聚乙烯管道浮起和变形。文章介绍了地基加固的方法以及管沟回填的步骤及要求,并从理论上分析了回填土的密实度与管道变形的关系。
After a typhoon attack, pipeline floating and deformation phenomena were observed in a high density polythene pipeline in Fujian province. By adopting foundation improvement and ditch backfilling, such phenomena were effectively controlled. This paper describes the foundation improvement method and the procedure and requirement of ditch backfilling, analyzes theoretically the relation between backfilled soil compactness and pipeline deformation.
