摘要
针对管道胸线以下外弧面与槽底基面形成的腋角回填区施工质量问题,分析了影响腋角回填质量的因素,探讨了在膨胀土地区PCCP管道腋角回填的施工技术要求,并进行了应用探讨,取得了较好的工程效果,据此提出大管径PCCP管道腋角回填的监控重点。
Regarding quality problems with axillary angle of backfilling area formed by outer surface below chest and bottom of the channel base, factors that have influences on quality of backfilling are evaluated. Technical requirements for backfilling of axillary angle in expansive soil area are discussed. Its application has achieved good result that helps to propose monitoring focus during backfilling of axillary angle of large diameter PCCP.
