3.3 Earthworks
IMPORTANT
■
Always remove the coalescence insert from the plant and store them safely during the
construction stage.
■
Protect the outlet opening of the outlet submersible pipe on site against soiling
or pollution.
■
The coating of the tank must be protected against damage, e.g. falling stones,
during filling.
3.3.1 Specifications
Installation site
■
Separator plants must be installed near the source of the light liquids.
■
Separator plants are to be constructed as far as possible outside areas subject to
traffic movements, but still be accessible for self-monitoring, maintenance as well as
removal and emptying.
■
Separator plants for light liquids should not be operated in flood-prone areas.
■
The plant must be easily accessible for cleaning vehicles.
■
The parking places for cleaning vehicles should be paved.
Installation depth
In Germany, the minimum depth for frost-free earthworks is regulated in DIN 1054. In
this standard, the depth is cited as min. 80 cm, but can be stipulated even higher due to
supplementary regional ordinances or empirical meteorological values.
Installation in groundwater
When the structural prerequisites make a buoyancy safeguard necessary, then the following
proposal for buoyancy safeguard applies:
The tank will have drill holes drilled in the factory, including delivery of short structural steel
pieces for connection to the on-site in-situ concrete structure to be erected by the customer.
Please note that we do not provide a reinforcement plan and that the calculation as well as an
associated reinforcement plan must be inspected and approved by a structural engineer (client's
obligation). We would be happy to do this for you for a fee.
Excavated pit
■
Excavation and back-filling per DIN 18300
■
Embankment / work space / shoring per DIN 4124
■
With normal ground conditions, a profile-following, compacted sand or gravel bed with
levelling accuracy will suffice.
■
Maximum ground pressure is 15.5 N/cm²
