在土方施工中,挖掘侧沟也是一项重要的工程,如田间路边沟渠的开挖、清淤,靠近建筑物的上下水道管路基沟的开挖等。目前国内工程机械、农业机械、建筑机械等行业所设计生产的各类液压挖掘机,均没有考虑侧沟的开挖和清淤。因此,各类侧沟只能用人工挖掘, In earthwork construction, excavation of side ditches is also an important project, such as excavation of ditches in the field roadsides, dredging, excavation of the foundation ditches of upper and lower sewers in buildings. At present, all kinds of hydraulic excavators designed and manufactured by domestic construction machinery, agricultural machinery, construction machinery and other industries do not consider excavation and dredging of side ditches. Therefore, all kinds of side ditch can only be manually excavated,
