Pile foundation drilling control method and equipment

The invention relates to a pile foundation drilling control method and equipment. Drilling a pile foundation hole along the axis direction of the steel casing by adopting a drill bit; and in the drilling process, inclination data of the currently-drilled pile foundation hole are obtained, and when it is judged that the current inclination of the current pile foundation hole is larger than a designed inclination threshold value, a drill bit higher than a current drill bit by one level is adopted for drilling to the current hole depth position. And the current drill bit continues to be adopted for drilling in the axis direction of the steel casing, and the steps are repeated till the current drill bit is adopted for drilling to the designed pile bottom elevation. The inclination degree of the drill hole can be judged in time by obtaining the current inclination degree, timely correction is facilitated, and the perpendicularity of the drill hole is guaranteed. And then the drill bit higher than the current drill
