Abstract: A trencher (machine) is a device used for digging trenches, used for laying pipes & cables, for setting up drainage or in preparation for trench warfare strategy. Also irrigation is very necessary for cultivation of crops. Usually rivers are far from agri-lands, which creates difficulty to irrigate. To overcome this problem of irrigation, pipeline have been developed which connects river with agri-lands. In present days, it is been followed manually with heavy machines, which results in high economic costs and time. Trenchless methods are attractive solutions in areas where difficult ground conditions exist, high groundwater table, or urban settings with highly congested infrastructure render open trench excavation highly undesirable. Such settings may include pipeline routings under a river, heavily travelled roadways, or railroad line.
