Connecting The Shaft Extension With A Shaft Adapter - Rehau Rausikko C3 X Einbau Und Wartung

05.07 Connecting the shaft extension with a shaft
adapter
A riser pipe ID500 of the required length is fitted on the
upper shaft element. Before connecting, a circular opening
of approx. 600 mm diameter must be cut out of the geotex-
tile filter, or, in the case of a retention, from the plastic liner
sheet. The geotextile filter or the plastic liner sheet with the
circular opening must be positioned over the opening of the
C3 shaft segment before connecting the shaft adapter.
The shaft extension is to be installed as follows:
1. For connecting the riser pipe,
insert the C3 shaft adapter in the
upper opening of the last shaft
element.
2. Cut the shaft extension pipe
with a fine-tooth saw to the desired
length. The cut is to be made along
the middle of a trough at a right
angle to the pipe axis without cutting open the section. Burrs
and bumps in the cutting surface are to be removed with a
scraper, a file or a knife if required.
