In application, if the soil layer in the pole pit is soft, just use two digging shovels to dig the soil smoothly. If the soil layer is relatively hard, the pull rope 25 can be pulled upwards to disengage the clamping block 51 from the first through hole 230 , and then the upper rod 23 can be pulled out from the base 4 . Insert in the base 31 of the upper end of the upper link 32, loosen the stay cord 25, and insert the block 51 into the through hole 310, so that the upper section bar 23 and the upper link 32 are connected as one. Press down firmly then, make clamping section 321 break away from deck 33, at this moment, can rotate upper section rod 23, drill rod 34 has been drilled into harder soil layer. In order to facilitate operation, a handle 22 is provided on the upper part of the upper section rod 23 for easy rotation operation.

In addition, it is also possible to draw depth lines on the two long operating poles, which is convenient for real-time understanding of the depth of the pole pit.

After actual verification, it was necessary to complete the digging in order to bury the electric poles. The amount of earth to be excavated was 1.5 square meters and took 1 hour and 15 minutes. Now the utility model is used for electric pole digging. When digging a pit, the amount of earthwork that needs to be excavated is only a little more than half a square meter, and it only takes 25 minutes to complete, and only one person is required to work, which saves time for engineering construction and greatly improves work efficiency.

To sum up, the present invention can reduce the excavation amount of earth and rock in the pole pit, and improve the operation efficiency. Simultaneously, for harder soil layers, the present invention can also be broken with drill rod earlier, and then carry out excavation operation with digging shovel. The electric pole pit excavated by the invention is a cylindrical deep pit, and after the electric pole is inserted and erected, less soil and rocks are backfilled and the stability is good.
