HSI 90/HSI 150. How to set in concrete correctly.
Installation: Connecting of duct for the single wall insert with plug-in
socket HSI 150-GSM
Following the process of setting in concrete and before
1
connecting the cable duct and remove the pipe cover
from the plug-in socket
At the HSI 150-GSM 160/X, the protective foil is removed
and the pipe cover of the plug-in socket is tapped in the
centre of the marked area and removed before connecting
the cable duct.
Before the process of installing the duct begins, the
bottom of the trench must be free from water and the
bottom bedding layer must be created by a professional
in accordance with the installation guidelines provided
by the duct manufacturer.
Mark the insertion depth (see table) on the cable duct.
2
Coat the inside of the plug-in socket with GMT lubricant,
and push the cable duct into the plug-in socket up to the
mark.
• Due to the relatively high coefficient of expansion
of thermoplastics, the longitudinal expansion of
the pipes at high temperatures must be taken
into account.
• The trench above the pipeline zone must be re-
filled according to the use of the pipeline route.
Compacting with heavy compacting equipment
is allowed only from a minimum covering of 30
cm above the pipe crown. High loads on the
covered pipeline during the building work, e.g.
driving over with heavy building machinery, must
be avoided.
