Assembling the and telescopic dome shaft
6.1
Assembling the telescopic dome shaft
The telescopic dome shaft enables infinite adaptation of the tank
to given site surfaces with earth coverage of between 455 mm
and 655 mm (Mini telescopic dome shaft) or 455 mm and
755 mm (Maxi telescopic dome shaft).
For assembly purposes, the enclosed profile seal (material
EPDM) is inserted into the tank dome's sealing groove and is
coated generously with soft soap (do not use mineral oil-based
lubricants, as these attack the seal). The telescope is then
greased, inserted and aligned with the surface of the site.
6.2
Telescopic dome shaft on which persons may walk
Important:
To prevent loads from being transferred onto the
tank, round-grain gravel
(max. grain size 8/16) is filled in in
layers around the telescope
and is evenly compacted.
Damage to the tank dome
and telescope must be avoided
during this step. The cover is then positioned and is sealed to
prevent entry by children.
Tighten the threaded connection
on the cover so tightly that it cannot be opened by a child!
6.3
Telescopic dome shaft over which passenger cars may drive
If the tank is installed under areas used by passenger cars, the
collar area of the telescope
(colour anthracite) must be
supported with concrete
(load class B25 = 250 kg/m²). The
layer of concrete to be installed must be at least 300 mm wide
and approx. 200 mm high all around. The permitted coverage
above the shoulder of the tank is min.
700 mm
and max.
1000
mm
. There are different possibilities for lengthening the
tank dome (315 mm): telescopic dome shaft with cast iron lid
or Begu (max. effective length 440 mm) as well as the Adapter
(max. effective length 300 mm).
Attention:
Use the cast cover under all circumstances.
6.4
BEGU telescopic dome shaft
On installation under areas used by cars with a maximum weight
of 3,5 t, the telescope
is supported as described in point 6.3.
The concrete rings
(Ø 600 mm) and a cast frame
with star-
shaped load distribution for mounting the cast cover are then
installed (observe earth coverage of at least 700 mm,
max. 1200 mm). The cast frame must have a supporting area of
approx. 1 m².
