管推進機。 A propulsion device 1 installed in the shaft 2 propels a small-diameter pipe 4 with a leading pipe 5 attached to the tip into the ground, and a cutter head 6 installed at the tip of the leading pipe 5 transports the excavated earth and sand to the leading pipe 5. And in a small diameter pipe propulsion machine that discharges soil by a screw conveyor 7 provided in the small diameter pipe 4, the screw conveyor 7 in the lead pipe 5 and the drive device 9 in the shaft 2 are provided.
A hollow drive shaft 8 provided in a small-diameter pipe 4 connects between the two, and the water sent from the drive shaft 8 to the screw conveyor 7 is used to slurry the earth and sand excavated by the cutter head 6 to form a sludge drain pipe. A seal 7 is installed at the rear of the screw conveyor 7 to maintain the mud pressure in the cutter head 6.
A small-diameter tube propulsion machine that uses both an auger type and a muddy water pressurization type.
