DN1200 network – Montpellier South Link

As part of the BRL network extension programme, and in particular the third tranche of work on the Montpellier South Link project, it was decided to supply and lay a DN1200 RCCPs (Reinforced Concrete with steel Cylinder Pipes) network over a linear distance of approximately 6200 metres in Lattes near Montpellier, France.

This project was divided into two main sections, “Mas Rouge” and “Rieu Coulon”, and required the use of various processes involving pipes of the specific size required:

• Pipes for open-cut laying;
• Sinker pipes for laying in watercourses;
• Pipes for laying inside ducts.
