Claims

[Scope of utility model registration request]

A small-diameter pipe 6 is connected to the rear end of a pilot pipe 4 buried in advance between the starting shaft 1 and the arrival shaft 3 via the excavation head 5, and while the small-diameter pipe 6 is propelled by the propulsion device 2. The excavation head 5 excavates the ground in front of the small diameter pipe 6, and the earth and sand excavated by the excavation head 5 is turned into a slurry and carried out through the slurry pipe 11 disposed in the pilot pipe 4, The slurry pipe 11 is connected to the sand pump 14 installed in the reaching shaft 3, and the slurry is sucked directly from the slurry pipe 11, and the slurry is transported to the ground using the lifting height of the sand pump 14.The small diameter pipe is buried underground. Machine soil removal device.
