水力开挖机组是80年代初为开挖养鱼塘而开发的挖掘机械新品种。近年来,已在水利、城建、河道与港口、市政建设等工程施工中,获得日益广泛的推广和应用。目前已有数千套机组活跃在全国各工地,年完成土方量近一亿立方米。是一种很有发展前途的土方开挖机械。该机模拟自然界水流冲刷原理,借助水力(水压为250～450kPa)冲切,泥浆泵吸排,可连续完成挖、装、卸、运、填、实等多道工序,
The hydraulic excavation unit is a new type of excavation machinery developed for the excavation of fish ponds in the early 1980s. In recent years, it has been increasingly popularized and applied in construction projects such as water conservancy, urban construction, rivers and ports, and municipal construction. Thousands of units have been active at various sites throughout the country, and the annual amount of earthwork completed is nearly 100 million cubic meters. It is a very promising earth excavation machine. The machine simulates the principle of natural water erosion, with the help of hydraulic (water pressure 250 ~ 450kPa) punching, mud pump suction row, can be completed continuously digging, loading, unloading, transport, filling, and other multi-process,
