An aluminum trench shoring system involves bracing the walls in a trench to prevent it from collapsing. This is a safer approach than shielding which is only designed to protect workers if collapse occurs. Aluminum trench shoring system is used when the ground is unstable. With their spring mounted flexible spindles, the trench shoring boxes can be installed with the “cut and lower” method. The range differs with regard to the thickness of plates and the safe working loads.
When it comes to construction projects, employee safety is always the number one priority. One of the most dangerous situations on any construction site is when workers are working in a trench, which can sometimes be several feet deep and in some cases many miles long. The biggest danger in these jobs is the walls caving in, trapping the workers under dirt and other materials. To make sure this doesn’t happen, companies today use a variety of equipment designed to make most any job safer.
Hydraulic Aluminum Trench Shoring System
Depending on the type of trench and its size, many different types of equipment can be used. Three of the most popular methods involve hydraulic shoring, soldier boarding and beam and plate. Hydraulic shoring uses a combination of hydraulic pistons and either steel plates or heavy plywood to shore up the trench. The plates or plywood are put into place, then the pistons are positioned and activated until they are pressing against the walls, creating a safe and secure work environment.
The beam and plate method involves using steel beams that are driven into the ground, which is followed by inserting steel plates amongst them to shore up the trench walls. On some jobs, wooden planks are used in the place of steel plates. While most people assume trenches are simply done to install pipes or other materials below ground, there are many other types of trenches dug to install such things as manholes. For these trenches, it’s just as important to ensure they are shored up in a safe fashion.
Some of the latest innovations in making these trenches safer involve using fin form material to take advantage of the pressure put on trench walls by the surrounding ground. Rather than making trench walls that are straight, fin form walls are angled slightly when first put into the ground. However, they then use the pressure exerted on them by the surrounding ground to bow out and become straight, thus creating a very tight fit that will almost never waver and collapse. These are used quite often in manhole construction, when spaces can be tight and narrow and the threat of collapse very high.Google+
