The invention discloses a strong ramming machine pile-forming monitoring device. The strong ramming machine pile-forming monitoring device can automatically detect state signals of a rammer hook and determine the number of times of ramming which is finished by a rammer according to the state signals of the rammer hook. Then, the determined number of times of ramming is displayed to a user through a display, and the user can conveniently know the work process of pile forming or hole forming in time. The strong ramming machine pile-forming monitoring device can automatically record the number of times of ramming, a machine is used for counting, an obtained result of the number of times of ramming is accurate and reliable, an engineering supervision unit or managers of a construction side can conveniently supervise and manage to a great extent, and the workloads of on-spot constructors are reduced.
