如果对铁路的土质路堤边坡不进行压实处理,就会降低路基的稳定性,影响工程质量。将挖掘机上的工作装置换成压实装置,则能解决边坡压实问题。 这种压实装置由框架式的承重结构和带有棱、槽的辊组成（见图）,用液压传动,液压马达与分流器直接连接,并装一个二级减速器。 If the soil embankment slope of the railway is not compacted, it will reduce the stability of roadbed and affect the quality of the project. The excavator on the work of the device replaced by compaction device, you can solve the slope compaction problem. This compaction device consists of a frame-like load-bearing structure and a roller with ribs and grooves (see picture). It is hydraulically driven. The hydraulic motor is directly connected to the diverter and equipped with a two-stage gear unit.
