5. Installation and assembly
5.2.3 Installation below HGV-bearing surfaces
The shaft can only be driven over with HGV in conjunction
with a self-supporting, iron-reinforced concrete plate. To
ensure that no additional forces or effects of HGV-bearing
are transferred to the tanks, the dimensions and strength of
the concrete plate must be statically calculated.
max. 500
If you have any questions in this regard, please contact your
GRAF-Team.
5.2.4 Installation adjacent to surfaces used by vehicles
If the underground tanks are installed adjacent to surfaces
>H
which are used by heavy vehicles weighing over 3,5 t, the
minimum distance away from these surfaces is at least the
H
depth of the trench.
5.2.5 Connection of several tanks
>500
Two or more tanks are connected via the
assembly surfaces by means of GRAF special
seals and basic pipes (to be provided at
construction site).
The apertures must be drilled to the
corresponding size using only the GRAF special crown bit. It must be ensured that the distance between
the tanks is at least 500 mm. The pipes must project at least 50 mm into the tanks.
