| How does it work? | |

Typically, utility installation or renewal will involve gaining access at either end of the run via pits excavated to the depth of the service to be laid or renewed. Equipment will then be placed in one or both of the pits and installation will take place beneath the area of ground between the pits. Or, as is the case with Horizontal Directional Drilling, the bore path can be guided to enter and exit the ground following the desired trajectory. |

The size of the pits will obviously depend on the technique employed
and the size of service in question. When laying services up to
about 32mm in diameter the Launch and Receive pits can be as small
as 750mm x 150mm and be 20 meters apart. A quick sum will show
that you are looking at about 15 times less excavation than a trench!
(see Open-Cut vs Trenchless
Comparison). |
