Build a Telephone exchange via Directional Drilling and Trenchers Edit

Directionl drilling CC owner Andrei(082 569 9154) recently did a project in Sandton where he trenced from driveway to driveway using a VibratoryPlow and TrenchingEquipment. Using a Horizontal directional drill he tunneled under each residents driveway. A 70mm pipe was layed through which the telephone wires and fiber optics were pulled via a wire for the DsLam telephone exchange. A Rod Pusher, Soil displacement mole, Piercing tool and HDD are the equipment used for trenchless pipe laying. An alternative method is to TelephonePoles for a DsLam exchange.


Head tracking Edit

GL- 505: the advanced 3-dimensional portable horizontal drilling tracking system

The GL-505 is the portable HDD tracking system, which automatically displays the 3-dimensional drill head positioning information in graphics. With GL-505, you can literally see through the ground. The display information is clear and unambiguous: it shows the position of the drill head as it is. The GL-505 does all of the processing automatically and continuously, providing the picture of what is going on under the surface.
Along with the positioning information, the transmitter telemetry and the steering data are displayed: the orientation of the drill head, the pitch, the temperature, and the battery status.
The transmitter uses the coded PSK modulation, which allows operating the tracker in the conditions of the severe interference from the power lines, industrial equipment and such. The operating frequency is optimized for the maximum locating distance.
The GL-505 family includes the locator, the wireless remote display for the operator of the HDD rig, and the variety of the downhole transmitters.

The locator was build using the BlackFin™ BF-531 DSP from Analog Devices. The DSP is running the sophisticated algorithms required to "see" through the ground.


Horizontal Directional Drill (HDD) Edit

http://www.horizontaldrill.com/services/hillsidestability.htm On Ebay used HDD vary in price between $8000 and $20000.

FTTH (Fiber to the Home) contractors in America use a HDD to lay fiber from the pavement to home. See: http://www.ditchwitch.com/dwcom/Category/CategoryView/11 attachment:hddDitchWitchJT921.jpg

Rod pushers Edit

Ditch Witch rod pushers are compact, economical, powerful and easily transportable solutions for long-distance trenchless installation of pipe, interduct, conduit and cable. Bore with directional control to 200 feet (61 m) or more with the P40; 500 feet (152 m) or more with the P80. http://www.ditchwitch.com/dwcom/Equipment/ProductFullSpecView/161 attachment:rodpusher.jpg

User Rod pushers about $3000 on Ebay

Piercing Tool Edit

The PT20, PT30 and PT40 will provide a low cost method of installing utility service lines under sidewalks, driveways, streets or other areas in which larger traditional trenching methods aren't feasible. Ditch Witch Piercing Tools perform short- to medium-range compaction boring projects, pipe ramming and pushing, and pipe pulling. On Ebay used DitchWitch piercing tools are $3000. http://www.ditchwitch.com/dwcom/Equipment/ProductFullSpecView/143

Soil displacement moles Edit

The GRUNDOSTEER on-board transmitter sonde provides pitch, roll and depth information, whilst above the ground a hand-held receiver/ locating device tracks the exact lateral and depth position and forward progress of the machine. This information can be passed on from the person tracking the machine back to the steering operator, therefore both operators always have a clear picture about the location of the machine.

The head is 75mm in diameter and can bore upto 60m. HDPE pipe can be installed by using the air hose to pull in the pipe after the bore is completed. The tool does not require any special drilling fluid to work properly. The Grundosteer is ideal for installations where directional drill rigs are impractical. A pit has to be dug for both the operator and Grundosteer.

Planar Construction project in Houghton Edit

Planar Construction layed CableFlex underground ducting accross boundaries in Houghton for residential homes setting up a fiber CctvCameras nework. Using GroundPenetratingRadar the owner Corrie Scheepers mapped out the underground topology marking any pipes. Adjacent each house he installed DrillBoxes from which the house connects to the backbone running down the perimeter. a Galvanised wire is blown through the CableFlex via a parashoot and compressor. With this Steel-wire the fiber and copper cables are pulled under the property boundaries to each home. The CableFlex ran down the length of the joint perimeter wall of the houses. Phone Corrie Scheepers Planar(083 413 1027) to lay cables under the road. Make a video of it, send it to Icasa and upload it to http://www.youtube.com as explained under LegalPerspective.

His next project was to link two banks branches in JHB CBD 15m underground a total distance of 100m using a soil displacement mole. See http://www.tttechnologies.com
