1. With built-in crusher mechanism, the pipe jacking operation through water-storing gravel layer is feasible..
2. Since the machine is of pressurized slurry type, it permits the pipe jacking operation over a long distance.
3. The hydraulic drive permits a free change in the number of revolutions within a specified range.
4. Because of its drive through the casing, no jacking load is applied direct to PV pipes to be berried.
5. Since the machine is compact in size, the operation can be started from a round shaft of 2 m in dia-meter.(when 1-m pipe is used)
6. The split recovery is possible from manhole IDΣ900m/m
