5.2.4 Connection of several tanks
Use the connection kit and DN 50 high-temperature
pipes to connect several tanks together. The connection
kit consists of 4 DN 50 special seals, 4 DN 50 HT pipes,
2 tension belts and lubricant.
Use the drill surfaces provided on the top and bottom of
the tanks to connect the individual tanks. You should
create the openings for the connections with a core drill
with a Ø of 58 mm. Drill on opposing sides of the two
tanks so that they can be assembled accordingly later
on. Insert the DN 50 special seal in the openings. You
should grease the seal with lubricant so that it is easier
to guide the pipes into the seals.
Use the wide side to push together the tanks in the
trench. When sliding the tanks together, slide the con-
nection pipes (DN 50 high-temperature pipe) into the
openings. Push the tanks together until the ribbing of the
two tank halves interlock and the tanks are touching
each other.
Lash the tanks together in the trench with tension belts
so that they don't move when you fill them. Fit the ten-
sion belts to the eyes on the side of the tank and the side
of the tank connection.
The connection pipes must not be shortened.
5.3

Insertion and filling

The tanks must be inserted, impact-free, into the pre-
pared trench using suitable equipment.
To prevent deformation, fill the tanks with water until
they are 1/3 full before filling the trench (check seal
integrity now). Then fill and seal the trench until it is 1/3
full with layers of max. 300 mm. You should then fill the
tank until it is 2/3 full and fill the trench with layers of
max. 300 mm until it is 2/3 full, etc..
The individual layers as well as the medial support
column must be well-compacted (manuel tamper).
Damage to the tank must be avoided during compac-
tion. Mechanical compaction machines must not be
used under any circumstances. The coating must be at
least 500 mm wide. Ensure that there is sufficient com-
paction, particularly in the bottom area between the
tanks.
Filling material:
• Chipping, 2/5 mm grit, topsoil
•
Excavated soil, filling sand, top soil, loam and other cohesive soils are not suitable for fill-
ing!
