以地埋线代替架空线,已成为当前农村电网建设的一条重要途径。我县的拖拉机手在手扶拖拉机配鼠道犁开暗沟的基础上,经过不断摸索改进,试验成功了一条多快好省埋地埋线的方法。他们在鼠道犁的犁头后面焊上一个拉环,系上电线,通过鼠道犁把电线引进洞道。开始也碰到很多困难,因为光打洞,洞深八十厘米,拉力就达两吨左右。而地埋线要求深一米,加上带四根线,拉力更重,钢丝绳易断,拖拉机固定也 Taking buried wire instead of overhead wire has become an important way for rural power grid construction at present. The tractor hand in our county, on the basis of walking tractor with plowshare and undergrowth, through continuous exploration and improvement, succeeded in a trial of a method of burying more and more burying land. They welded a pull ring behind the plowshare of the rat plow, tied it to a wire, and introduced it into the tunnel through a plow. The beginning also encountered many difficulties, because the light hole, hole depth of 80 cm, pulling up to about two tons. The buried line requires one meter deep, plus with four lines, pulling more weight, wire rope easily broken, tractor fixed
