摘　　要：管道细土回填是管道铺设过程的关键环节,直接影响管道的建设质量、运行安全及使用寿命,在山区和戈壁地段,施工现场缺乏足够的回填细土,因而制约管道施工的顺利进行。介绍了管道细土回填的要求,回填土的来源以及细土回填设备的发展。指出可在挖掘机或装载机上安装筛分破碎铲斗,既能筛分细土又能直接破碎石块形成细土,可以获得符合要求的回填细土;通过在挖掘机上加装撒灰料斗、管侧压实振动夯实机等液压快换接头,配合管道细土回填设备,能够进行塌陷管道外露灾害的防治处理。Fine soil backfilling is a key step in pipeline laying. It directly affects the construction quality, operation safety and service life of pipeline. In the mountains and Gobi deserts, the lack of enough fine soil for backfilling can restrict pipeline construction process. In this paper, the requirements for fine soil backfilling, the source of backfill and development of backfilling equipments are introduced. It is proposed that the screening and crushing bucket installed on excavators or loaders can not only screen fine soil, but also crush stones to fine soil, subject to relevant requirements. In addition, as supplement to the backfilling equipment, some hydraulic quick couplings, such as ash hopper and pipe-side vibration compactor, can be added to the excavator, so as to prevent and handle the exposure of collapse pipeline.
