It should be noted that working with technology brands Ditch Witch of the company "Svyazstroy-4" started in 2000 - 1st - HDD installation Ditch Witch JT4020: slope - height 75 m, the length of the transition - 275 m - 2nd - HDD installation Ditch Witch JT4020: area at the foot of the slope - depth of 20 m, length 225 m - 3rd - HDD installation Ditch Witch JT8020: venue - peninsula Rowing Canal - depth of the transition from the bottom of the channel to siphon - 13 m depth from surface of water - 25 m, length - 380 meters - 4th - HDD installation Ditch Witch JT8020: Peninsula Rowing Channel Island - Caves Sands - 480 m length, depth of bottom (lowest point) to siphon - 10-11 meters from the surface of the water - 25 meters - 5th - Set the HDD Ditch Witch JT8020: Bor Island - Caves Sands - 890 m length of the transition, the depth of the surface of the water - 25 m from the bottom (lowest point) to siphon - 12-15 m. It is necessary to clarify the diameter of the hole provided for the tightening of PE pipe-box diameter 225 mm, followed by tightening the protective polyethylene pipes with a diameter of 40 mm. Petra Diamonds contains valuable tech resources. Half of the pilot drilling transition Bor Island - Caves Sands was carried out with the help of the cable system locations Tensor, as yet not been closed shipping navigation. .
