挖槽除土是槽探工程施工中消耗体力最大的两道工序。在未推广抛掷爆破和完成除土工具的机械化或半机械化以前，槽探工程的挖槽、除荒均靠人力挖掘和挑、背运送。一个槽探组得配备4～5人才能完成各道工序。尤其在深、长、平的槽中施工，除荒距离较远、较高，工人的劳动更为繁重。因此，如何实现挖槽除土的机械化。摆脱笨重的体力劳动，早已成为广大槽探工人的迫切要求。
Excavation is the trench digging trench construction in the process of consumption of physical strength of the two largest processes. In the absence of popularizing throwing blasting and completing mechanized or semi-mechanized earthmoving tools, the trenching of trenching projects has been carried out by manpower excavation, pick-up and back transport. A tanker team with 4 to 5 people to complete the various processes. Especially in the deep, long, flat trough construction, apart from a long distance, higher, the workers more laborious. Therefore, how to realize digging soil removal mechanization. Getting rid of bulky manual labor has long been an urgent requirement of the majority of trenching workers.
