挖掘机的优缺点以及使用范围。

日期:2018-10-31   来源:/
挖掘机作为土石方作业施工的首要机械之一,它具有产量大、效率高的长处,缺陷是机动性差。选用大型挖掘机施工时需考虑的要素是工程量的巨细,运送条件和地形条件等。在公路工程施工中,比较合理的做法是:遇到大工程量像填筑高路堤和开挖较大的路堑时,安排施工时选用挖掘机合作运送车辆。
Excavator is one of the most important machines in earthwork construction. It has the advantages of large output and high efficiency. The defect is poor mobility. When choosing large excavators for construction, it is necessary to consider the size of the project, transportation conditions and terrain conditions. In the construction of highway engineering, it is more reasonable to use excavators to transport vehicles when large quantities of works such as filling high embankment and excavating large cutting are encountered.
