3.3.11 Leak test
WARNING
Danger of injury caused by incorrect execution
■
Any resulting buoyancy forces acting on the cover plate due to the water
filling must be compensated for by applying an additional load to the shaft
structure.
All drainage systems on private ground must be leaktight (only applies to Germany. Provisions in
other countries can vary).
The requirements and provisions for the leak test sequence must be enquired about for each
individual country.
IMPORTANT
■
Leak tests must be executed on the whole plant by a specialist company before
backfilling the excavation pit.
■
Fill the separator chamber first.
