The invention provides a drilling verticality monitoring and deviation rectifying method along with a drilling process, and relates to the field of auxiliary devices and methods for drilling cast-in-place pile construction. The drilling verticality monitoring and deviation rectifying method along with the drilling process comprises the following steps that S1, a drilling machine is in place, and after the drilling position is confirmed, the drilling machine is moved to a construction position; and S2, a verticality monitoring system and a drill bit deviation rectifying system are installed, firstly, a verticality inductor is placed in a drill bit of the drilling machine and fixed, three positioning emission receivers are arranged on the ground around a hole to be drilled, the three positioning emission receivers are connected with a computer terminal through cables, and the drill bit is provided with a hydraulic deviation rectifying device. According to the method, the verticality of the inner wall of the dri
