6.1 Fitting telescopic dome shaft
The telescopic dome shaft allows the tank to be variably
adjusted to the given ground surface. For assembly, the profile
seal (EPDM material) of the tank dome is generously rubbed
with soft soap (do not use mineral oil-based lubricants, as these
attack the seal). The telescope is then also greased, inserted
and levelled to the ground surface.
6.2 Telescopic dome shaft (pedestrian loading)
To prevent loads from being transferred to the tank, the
telescope is filled in layers (< 300 mm) with round grain
gravel (max. grain size 8/16) and compacted evenly.
Damage to the container tank dome
avoided. Then place the manhole cover in position, screw the
cover lock shut with a hexagon spanner and tighten it so that it
cannot be opened without tools.
6.3 Telescopic dome shaft (driven on by cars)
If the container is installed under car traffic areas, the
telescopic must be underlaid with concrete
B25 = 250 kg/m²) in the collar area. The concrete layer to be
filled must be at least 300 mm wide and approx. 200 mm high
all round.
Only for telescopic manhole for cars: Close the manhole cover
with a hexagon spanner and tighten it so that it cannot be
opened without tools.
6.4 Universal telescopic dome shaft
For installation under lorry traffic areas, the telescope
shimmed as described in point 6.3 above. The cast frame
provided by the customer or the concrete rings
provided by the customer are then installed to distribute the
load on the cover. The cast frame must have a bearing surface of
approx. 1 m² so that the load forces cannot be transferred to the
manhole casing under any circumstances.
Attention: It is essential to use a class D cover.
