Hole opening device for construction project detection

The utility model discloses a perforating device for construction project detection, which comprises two support brackets for supporting the whole device and a transverse support plate for connecting the support brackets, and the transverse support plate is fixedly connected with the two support brackets respectively. According to the perforating device for construction engineering detection, through mutual cooperation of the supporting bracket, the transverse supporting plate, the perforating mechanism and the lifting mechanism, the perforating mechanism is effectively supported through the supporting bracket, so that the whole perforating mechanism can always move in the vertical direction relative to the ground in the whole perforating process, and the perforating efficiency is improved. According to the tapping device for the pickaxe drill rod, the situation that the tapping direction deviates in the tapping process, and consequently the tapping effect is affected is avoided, meanwhile, through the arrang
