Rising Main Replacement with GRiPSHORE
RISING MAIN REPLACEMENT SUPPORT
As part of the Yorkshire Water AMP 6 programme, the MGF Yorkshire Depot supported Barhale to safely conduct an existing rising main replacement along Wigton Lane in Leeds, using the innovative safety solution GRiPSHORE®.
GRiPSHORE® is MGF’s new lightweight shoring range which combines GRP (Glass Reinforced Plastic) materials with Trench Jacking Theory.
THE SOLUTION
Working with the engineering department at Salford University, MGF’s research and development engineers combined light, flexible GRP materials with Trench Jacking theory to divert the loads from the soil onto the jacks and create a safe working environment quickly.
GRiPSHORE is lightweight enough to transport in a van and very quick to assemble when reactive maintenance is needed for utilities works.
The size and value of the properties along Wigton Lane have earned it the nickname ‘Millionaires Row’ and as the existing main has deteriorated bursts and emergency repairs have caused widespread disruption including road closures and diversions.
The installation of the new main will solve this problem.
The existing main currently pumps waste water from Alwoodley Pumping Station to the local wastewater treatment works along Wigton Lane. The team are laying the new sewer on the opposite side of the carriageway to the existing sewer – so that the existing sewer can stay in use during the works.
The final part of the scheme will involve shutting down Alwoodley Pumping Station and diverting flows into the newly laid rising main.
Barhale commented:
“Vertishore’s provide a lightweight, innovative way of safely supporting excavations within certain types of ground, up to certain depths. Due to the nature of the ground beneath Wigton Lane, the team have been able to utilise this product as a great way of advancing the operation quickly, whilst providing the same levels of safety as the traditional sheet and frame methods.”
THE VERDICT
This project was a success, seeing completion in early 2017.
