Trench support
Trench support
Shoring involves the use of shores or props to hold up or support some unstable or weak thing. When the workers are excavating, shoring systems are used for the safety of the workers and to speed up the excavation work. This is known as trench shoring.Trench shoring is the process of bracing the walls of a trench to prevent collapse and cave-ins. The phrase can also be used as a noun to refer to the materials used in the process.
Several methods can be used to shore up a trench. Hydraulic shoring consists of using hydraulic pistons which are pumped outward till they press against the walls of the trench. Usually, prefabricated struts and aluminium or steel wale systems are used in this method.
Another method is called beam and plate, in which steel I-beams are driven into the ground and steel plates are slid in amongst them.
The other type of shoring is known as pneumatic shoring. It performs the same functions like the hydraulic shoring, except that it utilizes air pressure instead of hydraulic pressure. The major limitation of this kind of shoring is that it requires an air compressor to work.
Hydraulic shoring is very popular as it is faster and easier to use. Other methods are generally used for long term applications and larger excavations.
