5.10.1
Alternative to Concrete Backfill (For Wet Sites Without Risers Only)
•
The option of securing the Tricel Pumping Chamber to a reinforced concrete slab or Deadman
anchor by way of straps may also be used, as shown below:
•
Tricel accepts no responsibility for the design of the concrete slab/Deadman anchor.
This solution should be designed by an on-site structural engineer to suit site conditions.
•
The straps should be positioned as close to the bolted joints as possible.
•
The reinforced concrete slab/ Deadman anchor must be installed after the level of the
ground water has been lowered, if necessary.
•
Once the Tricel Pumping Chamber has been secured by the straps, the backfilling with
concrete or gravel can commence.
5.10.2
Sloping ground
When the slope of the ground is 5% or more, it is recommended to install a retaining wall to protect the tank
from lateral thrust. Concrete backfill may also in some cases be sufficient to protect the tank. A qualified
structural engineer must determine if a retaining wall is required in the presence of a steep slope as shown in
the picture below:
