FILLING IN THE PIT

GENERAL PRECAUTIONS

- To prevent abnormal deformations of tanks and inspection turrets, during filling-in operations always keep the
level of the water inside above the filling-in level.
- Take special care to ensure that the infill material is evenly compacted across the whole external surface of the
tank, to prevent the formation of air pockets which would cause variations in the pressure applied to the tank,
leading to deformation and/or failure.
- Covers and caps must only be removed to fill the tank and absolutely must be in place during filling-in
operations.
- The tank must never be filled when outside the pit.
- NEVER fill in the pit with excavation spoil.
TANKS WHICH MAY ALSO BE EMPTY DURING OPERATION
Apply the infill material in layers of 15/20 cm, first filling the tank with water
and then filling in as shown on the left, with lightweight or lean concrete.
The infill concrete must be liquid so that it covers the entire outer surface of
the tank, up to its top level.
This backfill must provide sufficient support and counterthrust over the
whole outer surface of the tank.
