Distance To An Upstream Underground Tank - Graf SICKER-BLOC COMPACT 300 Anleitung

Examples of suitable traffic areas are:
Car parking spaces
Accesses for parking areas
Private roads
Access routes
According to RStO12 these areas belong to load category Bk0.3. This means a number of 300,000 equiv-
alent 10-tonne axle crossings, spread over a lifetime of 50 years.
Installation in the vicinity of the following traffic areas is not permitted:
Public roads or traffic areas
Traffic areas with speeds >30 km/h
Traffic areas without load limits regulated by marking
Traffic areas without constructional restrictions
Areas with a regular volume of 8 trucks (with a total weight of 30 tonnes) per day
Traffic areas in the vicinity of air, rail, port operations or other land use of special vehicles
GRAF can be contacted in the event of a different installation situation or ambiguous traffic areas, such as
a crossing or installing a heavy-duty crane.
Public roads are subject to substantially greater static loads so a sufficient distance must be maintained
from them. The distance (A) should be selected such that the forces arising (static and dynamic) from the
public roads do not impact on the system.

3.1.6 Distance to an upstream underground tank

If the infiltration elements are installed behind a rainwater harvesting system, a sedimentation tank or a
small wastewater treatment system, it must be ensured that no seepage water enters the excavation pit of
the underground tank. The distance A to be maintained is the difference between the installation depth of
the underground tank and the infiltration system, multiplied by 1.5. However, the minimum distance be-
tween the underground tank and infiltration system must not be less than 2 m.
