NOTE: Do
not rotate the driving sleeve during the
work.
• the extension rods are fitted with a
guide pin, which during work pushed
into the preceding rod. Start the driving locking the line
into the hardened tip with the leading
rod. Based on
that and the maximum earthing resistan-
ce can estimated how much line is
needed.
- both stop; stone rock has been found. When the appropriate
value reached, driving interrup-
ted and the last extension tube is
withdrawn (and can therefore be
reused).
Practical advice:
1. Arrange parallel earth
connection necessary.
- the rod continues and the line stops; the
line has come loose and can pulled up
or the tip has folded.
• earthing resistance can measured
continuously. Preferably measure the earthing resi-
stance continuously while driving down
the earth line.
4. Resistivity different soil conditions.
3.
5.5 times the
line length already driven down. Plan the earth connection.
. Determine the soil resistivity.
3. The earth line locked the hardened
steel tip with the leading rod.

What are the soil conditions?

In the event interrupted driving, start

power hammer should used. does not, there are the following
possibilities:
- more rods than line required; the rod
may have been bent and then runs
parallel the surface the soil and the
line does not follow the pipe through the
ground.

Structure and operation the system
Elpress systems consist the
following parts:
• hardened steel tip
• leading rod
• extension rod
• driving sleeve/impact sleeve
• earth line (not supplied Elpress)
This feature simple
• the earth line inserted into the
hardened steel tip and clamped the
leading rod. Measurement ground resistance.
If the stone does not shatter after about
10 seconds, you must start over. Splicing and bran-
ching the earth line contact crimped
by means Elpress through connectors or
branching sleeves and tools. loose soil, a
sledgehammer and impact stud suffi-
cient
