5 times the line length already driven down. 5. Measurement ground resistance.11:3 11 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. What are the soil conditions? Normal and loose soil steel pipe 17 mm sufficient. • the extension rods are fitted with a guide pin, which during work pushed into the preceding rod. The earth line locked the hardened steel tip with the leading rod. Based on that and the maximum earthing resistan- ce can estimated how much line is needed. 3. When the appropriate value reached, driving interrup- ted and the last extension tube is withdrawn (and can therefore be reused). Start the driving locking the line into the hardened tip with the leading rod. Arrange parallel earth connection necessary. Splicing and bran- ching the earth line contact crimped by means Elpress through connectors or branching sleeves and tools. In the event interrupted driving, start again distance least 1. Determine the soil resistivity. . Hard and rocky soil- steel rod mm (type HD) should used. Resistivity different soil conditions. heavier soil/at greater depth, a power hammer should used. Plan the earth connection. - the rod continues and the line stops; the line has come loose and can pulled up or the tip has folded. Practical advice: 1. 3. Driving starts. 2. 1. If the stone does not shatter after about 10 seconds, you must start over. mm² line should folded double before the tip attached. • earthing resistance can measured continuously. loose soil, a sledgehammer and impact stud suffi- cient. Make sure that the line maintains the same speed down into the soil the rod. parallel earth connection possible? 2. Preferably measure the earthing resi- stance continuously while driving down the earth line. NOTE: Do not rotate the driving sleeve during the work. 4. 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. - both stop; stone rock has been found
