The invention provides a jet-type hole forming tool. The jet-type hole forming tool comprises a Luoyang shovel with a hollow shovel handle, an air supply pipeline is connected to an air inlet of the tail end of the shovel handle, and an air blowing hole facing to a shovel body is formed in the other end of the shovel handle. The width of the shovel body is greater than the diameter of the shovel handle. The jet-type hole forming tool uses the shovel body at the front end of the Luoyang shovel to cut soil mass, the soil mass cut by the Luoyang shovel is blown by an air jet formed by high pressure air generated by an air compressor, the soil mass is discharged from a gap between the Luoyang shovel and hole bodies, disturbance to the soil mass is less, hole collapse is not prone to being caused, the hole collapse rate is low, power consumption is low, energy is saved, the construction speed is high, hole forming efficiency is high, and the construction period can be effectively shortened.Meanwhile, the number of construction personnel is small, the use position of equipment is flexible, a required working face is small, and disassembly and installation are convenient.
