-The GROUND MOLE provides accurate horizontal boresbeneath roads, railways without trenching the ground.By boring with Ground Mole, underground supply linessuch as pipelines for gas, water, communication and engerycables can easly be furnished underground without anydamage to the structures on the ground. Furthermore, daily life is not disturbed while operating.- FABU GROUND MOLE rockets are manufactured indiameters of 77 mm., 97 mm., 132 mm., 160 mm., 190 mm.and 240 mm. The diameter of the hole to be bored determines the diameter of the rocket to be purchased.- The Ground Mole operates underground, moves in horizontaldirection with forward and backward motion. 1. Minimum manpower is used in target determination and start up. > DiameterAir ConsumptionWeight Length MODEL I N C H M MKG I N C H M M LBS P S I B A R C F M M 3 / M I N FK 240 9.4524073.7187387 935425 6262 7.5 FK 1907.4819073.2185987 528240 6210 6.0 FK 1606.3016073.1185787 411187 6140 4.0 FK 1325.2013263.6161587 231105 6105 3.0 FK 973.829760.1152887 14365 652 1.5 FK 773.037759.6151587 8639 642 1.2 2 . D e p t h D e t e r m i n a t i o n : The movement axis of the rocket should be in the depth (h) of 12-15 times of the diameter of the rocket.3. The longer the distance to be bored, more sensitive the target determination is, therefore good observation and precise aligment is essential.4. Distance to be bored : Distance to be bored depends on the appropriacy of the ground formation, theair temperature and the air pressure applied. In general use, a distance of 100 meters can be performed.5. Starting plate is placed approximately 40 cm. away from the surface to be bored and is fixed on the ground in the direction of the arrow by means of four ground spikes. 6. Rocket is placed on the starting plate and tightened by means of roller bolt. 7. Target is determined. 8. For forward motion of the rocket the air hose is turned to the right, for backward motion of the rocket the air hose is turned to the left till the end. 9. It must be checked that the air hose is turned to the right while the rocket is on the starting plate. Otherwise, the gear part and the other moving parts of the roller can be damaged.10. Air feeding valve is openned half until the rocket leaves the plate completely and then the valve is fully openned.11. Boring speed is 5-10 meters/hour in average in a soil or clay formation when the air pressure is 87 PSI - 6 Bars . 12. To remove the rocket from the bore: The plate is removed, the air feeding valve is closed and the air hose is turned to the left till end. Then, the air feeding valve is openned and the rocket starts moving back. >
