At the same time, in the propulsion device that buries the pipe while discharging excavated earth and sand with a screw auger, an auger bit is attached to the tip of the screw auger, and the inner peripheral surface of the shoe, which the auger bit contacts with its own weight, is eccentrically placed. form,
A tube propulsion device characterized in that the center of the orgabit is substantially aligned with the center of the shoe.

Claims

[Scope of utility model registration request]

In addition to providing a guide tube at the tip of the tube with a shoe that can correct deviation, a casing pipe is placed inside the tube following the guide tube, and a screw auger is inserted into the inside of the casing pipe, and the screw auger excavates soil. In a propulsion device that buries a pipe while discharging it and pushing it forward, an auger bit is attached to the tip of the screw auger, and the inner peripheral surface of the shoe that the auger bit contacts with its own weight is eccentrically formed.
A tube propulsion device characterized by aligning the center of an orgabit with the center of a shoe.
