The present invention relates to an excavating screw for conducting a trial excavation at a position where an electric pole or an earth wire is to be installed, when constructing a mechanizing electric pole or performing earth connection. To be more particular, during trial excavation for locating buried objects before burying the earth wire and standing the electric pole, the waste of manpower can be reduced by performing mechanized excavation using an excavating screw and also working hours can be significantly reduced. In particular, the burying supporting power of the electric pole or the earth wire being constructed later can be sufficiently secured by excavating only a necessary part in order to maintain the bearing capacity of the soil. In addition, the present invention relate to an auger crane having a camera for locating buried objects and an excavating screw for a backhoe, which can prevent damage to buried objects and safety accidents accordingly by rapidly detecting the buried objects during a trial excavation through continuous observation on the lower ground surface being excavated during excavation. |
