Critical Trench Box Safety Tips

The digging of trenches is an important component of a variety of constructions and engineering sites. They are used for laying telephone lines, pipes or any other type of tubular structure that has to be installed underground, such as oil rigs, etc. Sometimes, trenching can become a demanding because the soil used in these areas has excessive levels of moisture. This creates difficulties when trying not only to eliminate any dirt that is accumulated around objects but also keep yourself secure during the procedure since accidentally exposing the skin can result in severe injury.

Trenches are essential for any kind of construction, or repair that needs to be completed in the ground. They are able to prevent collapse depending on the type of soil and the quality. Trench boxes are made using steel/aluminum frame to temporarily secure them before excavation commences. The grout is secured between two layers when necessary, to ensure that there are there are no cracks when placed at the site level.

Pre Installation

Before digging gets underway, it is essential to consider the potential dangers that are involved. This involves knowing what equipment is needed and the number of people have access. It also allows you to think about alternative methods of accomplishing the task without placing your life at risk. A thorough risk assessment should also take place during pre-excavation surveys so that all possible dangers can be easily identified prior to the event; this will help minimize the risk of unexpected problems later on.

Also be aware of the depth of your trench. It will require support from either sloping, or shoring, if you have a an area of 5 feet in width. However, if the trench is deeper than 20 feet, it will require more engineering work. This is due to the lack of straight sides at either end. Anyone who builds above the ground needs to consider the possibility of foundation moving.

The trench should be accessed by a ladder or steps, or by a ramp. Safe access must always be at least 25 feet from workers in the event of an emergency. The trench box may also be used to check for low oxygen levels, toxic gasses and other problems. The setup of these articulated devices is simple, however they increase the chance of stacking them on top of one another because you do not know the height at which your piles will reach into their weak bottom.

Care Take care of the trench

1. Make sure to inspect the trench box or support on a regular basis for any signs of damage, and any movement.

2. On-site, all personnel should wear their safety gear and have a steel-toed boot as well as high-visibility clothing.

3. The heavy equipment and tools must be placed at least three feet from the edge of the trench.

Extraction

Because the ground around trench boxes moves, it is more difficult to set up than to take it out. Chain slings can be used to pull soil out, and there are three options for lifting it. The final method is by using an overhead crane.

1. Straight Pull: This is the most basic of all extraction methods. You simply need to attach your sling to two points and then raise it up.

2. Half Pull: When you use half-pulls, connect it to one side of the trench box and lift as much as possible before moving it to the other side. This will allow you to clear all debris and dirt inside the trench without causing damage to your lawn.

3. Single Pull: You connect one chain leg to your lifting/extraction location. Each panel will be lifted in turns. Use your pull to remove the trench box.
