The invention discloses a steel trestle pile foundation ring cutting method pile implanting process in a bare rock area. The steel trestle pile foundation ring cutting method pile implanting process in the bare rock area comprises the following steps of preparing for construction, hoisting, placing and reinforcing a drilling platform, placing a drilling tool steel pipe pile, preparing before drilling, carrying out drilling and finishing drilling. The steel trestle pile foundation ring cutting method pile implanting process in the bare rock area resolves the pile implanting problem that hammering or vibration construction can not be adopted for a steel trestle pile foundation in the bare rock area, the steel pipe pile with the pile end welded to alloy steel drilling teeth is driven by a revolving drilling machine on a construction platform, and after a rock surface is drilled by a certain depth, the steel pipe pile is directly embedded on a base rock. The steel trestle pile foundation ring cutting method pile implanting process in the bare rock area is suitable for the shallow coverage or bare rock area, simple in work procedure, easy to operate, and safe and reliable in construction.
