国外开沟机技术现状及产品特点

Present Technology Situation and Features of Foreign Trencher

开沟机是一种用于土方施工中的开沟机械,与挖掘机的功能具有许多相似之处,二者均具有入土（土壤或岩石）、碎土和取土功能,不同之处在于开沟机能连续作业,施工效率高,地表破坏小,特别适合铺设管路,即使在岩石等坚硬的地质条件下,开沟机也能开挖出形状规则的沟槽。

Trencher is a kind of ditching machinery for earth work.It has many similarities and differences functions with the excavators. The similarities of the both are digging (soil or rock),crushing and loading. The differences are that trencher can be continuous operation with high efficiency and small surface damage,especially for the laying of pipes.It also can make a regular groove even in hard rock and other geological conditions.In this paper,we will introduce the present technology situation and features of the foreign trencher.
