することを特徴とする管埋設装置。 A casing with an auger screw inserted inside the pipe to be buried is installed, and the excavated soil is passed through the casing by the rotation of the auger screw while excavating the ground at the tip with the excavation head installed at the tip of the auger screw. Transport the soil to the shaft side and remove it.
In a pipe burying device that buries a pipe underground by pressing the rear end of the pipe at the same time, there is a stirring blade disposed on the circumferential surface of the rod part of the auger screw at the rear of the excavation head; a pinch valve having an expansion and contraction body made of a flexible material that is disposed around a rod portion in the rear portion and expands and contracts in directions toward and away from the rod portion by supplying and discharging fluid; and the expansion and contraction body of the rod portion. A pipe burying device comprising: a rotary tube rotatably fitted to a contact surface of the stirring blade; and a slurry material supply means for supplying slurry material to a portion of the stirring blade.
