Perpendicularity and penetration auxiliary device for hammering construction of precast pile and using method of perpendicularity and penetration auxiliary device

The invention provides a precast pile hammering construction perpendicularity and penetration auxiliary device and a using method thereof.The precast pile hammering construction perpendicularity and penetration auxiliary device comprises a penetration ring, pushing pieces, a controller and an alarm, the penetration ring is used for placing a precast pile in pile foundation construction, the four pushing pieces are all arranged on the penetration ring and distributed in a cross shape, and roller range finders are arranged on the pushing pieces and comprise rollers; the roller is arranged at the tail end of the pushing piece and makes contact with the precast pile, the controller is fixed to the penetration ring and used for processing the distance measured by the roller range finder and the extension value of the pushing piece, and the alarm gives an alarm when the distance measured by the roller range finder meets the penetration limit value. The device can assist in adjusting the perpendicularity and penetra
