Large pipes made to order for rail drainage project

Rocla® recently supplied special pipes for drainage works along a rail line which were custom designed and manufactured to withstand lateral loadings and aggressive conditions.

The drainage pipes were part of the Revesby Turnback project, which will improve the efficiency of rail services in southwest Sydney through the construction of a turnback (train turnaround track) and new terminating platform at Revesby Railway Station.

For the new drainage works around the station and railway corridor, consulting engineers Hyder requested special reinforced concrete pipes with the strength to withstand lateral loading and enhanced durability to cope with the expected semi-aggressive water conditions.

The performance criteria specified by Hyder required a concrete pipe material with special requirements for the reinforcing, concrete strength mix and cover to reinforcement.

Rocla®’s engineering department provided a custom pipe solution that allowed the pipes to be manufactured to the strict durability requirements, with a water absorption ratio of less than 6% (in compliance with the new standard AS4058: 2007).

Rocla® supplied 103 metres of 1800mm diameter RRJ pipes and 310 metres of 1500mm RRJ pipe to the lead contractor, Thiess United KG Joint Venture.
