轮胎压路机(又名气胎碾)和振动压路机(又名振动碾)是填筑工程中不可缺少的两种压实设备。振动压路机已开始使用于大秦铁路施工中,但轮胎压路机在铁路施工中还很少使用。其实,振动压路机的效能更适用于颗粒松散的砂性土壤,而轮胎压路机对于粘性土壤则具有更高的压实效能,国内在水利和公路等部门已大量采用轮胎压路机,他们都能证实这一点。因此应按照不同的填料性质选用不同的压实机具,以求得最佳压宴效果和最大的经济效益。
Tire roller (also known as pneumatic tire grind) and vibration roller (also known as vibration grind) is an indispensable filling construction of two kinds of compaction equipment. Vibratory roller has been used in Daqin railway construction, but the tire roller is still rarely used in railway construction. In fact, the performance of vibratory roller is more suitable for loam particles of loose soil, while the tire roller for sticky soil has a higher compaction efficiency, the domestic water conservancy and highway departments have extensive use of tire roller, they can confirm this point . Therefore, different packing materials should be used according to the nature of different compaction equipment, in order to achieve the best pressure feast effect and the greatest economic benefits.
