Overview of the requirement:

• Pressure relief wells within the retaining walls
• Inflow rate: 5L/s per 100m of structure
• Diameter of wells 250mm
• Depth of wells: 15m deeper than final excavation level
• Wells filled with aggregates type 6C
• 2 Wells per row every 20m (best case) or every 5m (worst case) all along Burton Green Tunnel and Burton Green Retaining Structure (from area GT5 to area RW1)
• The pressure relief wells would evacuate any artesian pressure that could destabilize the ground during excavation works. Underneath the top slab, transversal ditches would be installed at every row of wells to drain inflow waters from the wells to the edge ditches running at toe of embankments toward the temporary balancing ponds
• The wells are trimmed as excavation works progress toward final excavation level.
• When final excavation level is reached, sleeves of the baseslab thickness are installed at each well location. These sleeves are embedded in the baseslab
• During baseslab works, water is evacuated through baseslab permanent ditches toward exit of tunnel and pumped away.
• When baseslab is complete, the sleeves are sealed with end plates and grouted. At that stage, the structure can withstand the uplift pressure.
