Trench shoring is a common technique in below-ground excavation. It’s also one of the most dangerous aspects of construction work, which should therefore be approached with caution and foresight. The right tools, combined with the right training and the right crew, will help to ensure that your trench shoring goes off without a hitch.
As with any construction project, trench shoring is subject to a number of requirements which are mandated by law. For example, any trench which is over 5ft in depth is required to have shoring, to ensure the safety of those working within. Soil evaluation also plays a large part in determining which types of tools and procedures should be implemented for any individual project, as do environmental factors such as nearby buildings, transport systems, pipelines or protected green zones.
Technical Requirements
The technical requirements of a trench shoring project are effected by both legal mandates and project specifications. Soil type will directly influence which types of tools are best to use, as well as how deep and how steep a trench excavation can be achieved, both safely and within the technical parameters of the project being carried out. Safety, however, should always be the primary requirement for any construction project irrespective of time, complexity or budget.
Health and Safety
The most important reason for making sure your trench shoring is installed correctly is that of health and safety. Trenches can be incredibly dangerous working environments and many accidents occur each year, some with catastrophic consequences.
The actual act of excavation is the most risky part of the entire excavation process. Because of this, many construction workers tend to prefer to use reinforcement methods that require as little human involvement as possible during the excavation process. Hydraulic shoring, for example, can be installed without the need for anyone to enter the trench.
The Benefits of Hiring a Contractor
Proper installation will also help to ensure that your shoring provides as much structural support as is possible. A qualified and competent contractor should always oversee shoring installation, as they will be able to identify potential risks and prevent them from developing. Contractors are also able to stop construction if an accident was to occur and to correctly oversee end-of-shift procedures which are designed to improve site safety, such as: weather effects, vibration, trench wall movement or bulging.
