Placement Of Charges
|
|
--------------------
|
|
|
|
In demolition work, the greatest problem is the actual placement of
|
|
the charges. When an individual is working on a large structure such as a
|
|
building or a bridge, it is imperative that he have an understanding of the
|
|
directional force of explosives, and the structure's weaknesses. These
|
|
large-type structures are built to bear up under abnormal stress, so the
|
|
chances are good, unless the charges are placed correctly, that the sabotage
|
|
will have little or no effect.
|
|
When attempting the demolition of a building, the first thing to do is
|
|
to determine the weakest point in the structure. This is the point where a
|
|
charge can be placed and well-tamped, and will result in maximum destruction.
|
|
A large building will usually take more than just one charge. The best bet is
|
|
to place large explosive charges on either side of a weak point in the
|
|
foundations. These charges should be tamped from the outside, so as to drive
|
|
the force inward.
|
|
There are several basic methods of planting explosives. The advantage
|
|
to most of the ones listed below is that they have a natural tamping factor,
|
|
built-in.
|
|
|
|
[1> Bury the explosive beneath the object of destruction.
|
|
[2> Drill a bore hole into the object and fill with explosives.
|
|
[3> Form a brace to hold the explosives tight against the object of
|
|
destruction. A good brace can be made from wood placed on a diagnol, with one
|
|
end jammed into the ground.
|
|
[4> Place a charge out in the open, with the tamping material surrounding it,
|
|
and directing its force.
