Erection of Poles – The poles are usually pressed directly into the

ground. The heavier poles are erected by the derrick pole method
and the lighter ones by the dead man method. These methods of
erecting pillars are described as follows.

(a) Derrick Pole Method


The paths on which the pillars are to be erected. The pillar to be
erected on that path is first laid. A derrick pole is erected by pulling
it with the help of a rope so that it rests near the bottom of the pole
to be erected. This pole is placed so that the bottom of the pole is
above the pit and on the opposite side of the skid board placed in
the pit. As shown in Figure (1), in this Method, the pole is tied with
five ropes a little below its summit so that the edge does not bend
while erecting the pole.

Rope number 2 is tied tightly to the top of the pole, as shown in


Figure (1), and this rope passes through the pulley on the derrick
pole. It is pulled by hand in the direction shown in Fig. (1). Rope No.
3 is tied on the pole. This rope is pulled to make the pole stand.
Along with this rope, number 2 is also pulled, and with the help of a
skid board, the pole slips down into the pit. In this position, the rope
is raised vertically using 1,3, and 4.
