The utility model relates to a transmission line is the ground auger for the engineering, ground auger can continue especially, and its structural feature lies in, still including the structure that continues, the drilling rod buries the festival including the ground auger and continues the festival with the ground auger, and the ground auger buries upper end and the ground auger of festival and continues the lower end of festival and respectively weld and have a butt joint, and two butt joint cross -sections are constructed the samely, the structure that continues is including transmission sleeve and joint coupling, and transmission sleeve cup joints ground auger the continue butt joint of the lower end of festival of upper end and the ground auger of festival of burying, and the oppositevertex in transmission sleeve of two butt joints at this moment touches and connects, the transmission sleeve cover inlays in the joint coupling, and the cross -section of joint coupling is unanimouswith the drilling rod. Its advantage lies in, have creep into quick, continue reliable, advantage such as install and remove the convenience, uplift force is big, the suitability is strong.
