4. Installation
4.9.2 Optional: connection set
Use appropriate and approved lifting
equipment, operating wrenches and
means of transport for transporting
and opening / closing the cover only.
Observe the maximum load of the shaft
cover also during the construction period.
Cover and extension pipe are generally
load separated, i.e., the extension pipe
is not subject to vertical forces from the
free cover bearing. The free bearing
transfers loads from the surface to the
cover directly to the load-bearing under-
ground.
The cast iron cover can be integrated in
the road surface without any problems.
As soon as the road superstructure is
being prepared, the bearing for the shaft
covers must be created.
Prepare a lean concrete bearing of min.
10 cm for a safe and free load transfer
from the cover to the building ground.
Include an expansion joint between the
bearing and extension pipe.
The bearing surface for the frame must
be even. The frame of the shaft cover
must rest on the bearing with its entire
contact area.
If the cover is outside the road, the
bearing for the cover must be prepared
separately at least from non-cohesive,
compactable material. The professional
compaction with appropriate equipment
is essential (compaction 98 % DPR
according to ZTV StB). If required, a
bearing made of lean concrete makes
sense in this case, too.
Using plate compactors or vibrating rollers
on the shaft covers is not permitted.
Clean the covers, in particular the contact
surfaces, after the work has been com-
pleted and/or after every opening.
Use common hexagonal wrenches M10
to screw connect the cover with the frame.
The optional connection set includes a class D shaft cover.
4.10 Filling the system
After the work has been completed, the
system must be refilled with water up to
the outlet. This is required to ensure the
retention of floatables and light liquids
through the immersion wall.
