Part pole should be planted below the soil surface is 1/6 of the length of the pole. So the depth of the hole depends on the length / height of the pole to be installed. On soft ground the bottom of the pole should be installed pads (concrete blocks) so that the poles embedded in the soil long 1/6 pole. From Figure 4-1 it appears that for the length of the pole 13 meters above the ground portion is 10.2 meters, 11 meters to the long pole that is above ground portion is 9.2 meters, and for a length of 9 meters mast section above the ground is 7.5 meters.
Work establish concrete pole begins by preparing the plans pole placement. Of the plans can be determined number of poles required and also determined the location where the pole will be established (marked with stakes). Next to erect the mast-do-langah following steps:
1) Prepare the working tools and equipment needed to set up the pole,
2) Distribute these poles to the location where the location of the pole will be erected,
3) Dig a hole at each place that will set up the pole,
4) If the excavation is ready, then the activities set up a pole can be done. Establish concrete pole low voltage (9 meters) can be done in two ways; first manually (conventional), which use a crane-hand and by using buffer (stairs). This method is carried out mainly in the pole planting locations that are difficult to reach with a tow truck. At low voltage pole (9 meters) it is most likely to occur.
Establishing the pole by hand done as follows:
1) Before the ladder to support the elevated pole, first concrete pole lifted by crane-arm,
2) tied a tow chain-hand on the center pole. -Hand crane is suspended from an iron tripod prepared for this job.
3) If a slab of concrete has begun dinailkkan, then followed with a ladder or other prop to push upwards.
4) In addition to controlling the direction of a slab of concrete at the time appointed, mounted rope slapped four (4) or 3 (three) stretched to a different direction, attached to the position (15-20)% of the upper end of the pole, to control the direction of the pole at when lifted.
5) Furthermore, the pole is pulled / pushed upward while control of the direction of the slap rope, until the base of the pillar approach and enter the hole.
6) For reinforced concrete pole before diuruk ground, note the direction of the bolt hole for an croos penempat arm.
7) If the direction of the hole is not in accordance with the pole just turn the tie on a pole, then the pole is rotated in accordance with the direction of the hole where the bolt is desired.
Furthermore Uruk with soil around the pole until solid. For the soft soil at the base of the pole needs to be installed or given foundation pads. Second, set up a pole with a lifter faster and practical, does not require a lot of manpower (see Figure 4-4). After the hole where the pole is prepared, then the pole is quite removed with lifter, and further assistance is needed to steer so that the base of the pole
