3.3 Installation
Carefully move the container into the excavated pit, e.g. by suspending it on cords, and align it
horizontally, taking the working space width into account.
Fill the container halfway to the top with water. For retention cisterns, outflow must be temporarily
halted, for example, by fixing the outflow throttle valve in a raised position.
Fill in the space between the outside of the container and the wall of the excavated pit in layers of
100 mm, compacting each layer (Figure 6).
A3: Backfilling material as defined under Item 2.1
A4: Filling as defined under Item 2.2
For walk on: 1 operation per layer using a hand tamper
For drive on with a car: 3 operations using a hand tamper (Figure 10a)
For drive on with a commercial vehicle: 3 operations using a hand tamper, 500 mm wide (Figure
10b)
Do not use machines for compaction in this area unless you have consulted us first.
Then: Fill the hole in the container with backfill material (A3*). Filling the hole must be done with
special care. Absolutely no hollow spaces may remain .
