Horizontal directional drilling for power cables
We pull protective ducts for power cables under roads, railways, rivers and built-up areas, without open trenches.
New power cables often have to pass under roads, yards and watercourses. Horizontal directional drilling takes them from one pit to another, without cutting the road or damaging green areas.
How we work
- We check the route and existing utilities, on plans and by radio detection.
- We drill the pilot bore, tracked from the surface and corrected in real time.
- We ream the bore to the size the diameter requires and pull in the pipe or ducts.
- We reinstate the pits and hand over the work.
Ducts for cables
We usually pull polyethylene protective ducts, one or several in the same pass, through which the cables are then pulled. The number and diameter of the ducts follow the design.
Where it is used
- road and street crossings;
- railway crossings, with a casing;
- river and canal crossings;
- built-up areas and yards, where open trenches would damage paving or green areas.
Permits
Crossing roads, railways and watercourses requires the approval of their owners. Which permit each obstacle needs: trenchless crossings.
What we need for a quote
- the location and the obstacles to be crossed;
- the length of each crossing;
- the network, pipe material and diameter, or the number of ducts;
- the geotechnical study and site plan, if available;
- the desired deadline.
How deep do the ducts run?
As deep as the design and the owner of the obstacle require. Directional drilling keeps the required level along the whole route.
