Shoring is a term
that refers to the practice of bracing the structure with the help of temporary
and strong structures to prevent collapse of the materials. While many people
may get confused between the terms shoring and shielding, they are totally
different. Shoring is the process of popping up structure to prevent collapse
of earth while shielding is use of safety methods to protect the workers in
case of a collapse.
Different techniques used in Trench shoring
- Soil Nailing
In this technique,
the soil nailing contractor uses
reinforcing, strong and elongated bars to insert them into the pre-drilled
holes. After that, they are sealed with binding material to hold the walls,
excavations, and soil slopes.
They are generally
planted in semi-downward incline without creating any tension. The soil nailing contractor normally uses
the lone soil nail heads or sprayed concrete.
- Beam and plate
In this technique,
beams are planted firmly on ground and they are reinforced with the steel
plates in between. The soldier boarding that uses wood planks also use similar
mechanism. This kind of shoring is normally used for excavation that may span
longer duration of time.
- Hydraulic shoring
In this method,
hydraulic pistons are popped up until they push against trench walls. Plywood
or steel plates are used with pistons. This kind of shoring is one of the
easiest methods amongst others.
By following the
safety rules every time, shoring can be used effectively without any accidents
or risks. Moreover, with the right equipment and supplies, it can be done
without any hassles.
