When you need to dig a trench, you have two basic options: trenching and blasting. Here's why trenching is actually the better choice.
What is trenching?
Trenching is the process of digging a narrow, deep hole in the ground. This process can be done by hand using a shovel, or it can be done with an excavator or other similar machinery. The purpose of trenching is to create a space for utility lines or other objects that need to be buried beneath the ground.
What is blasting?
Blasting, sometimes called rock blasting, is the process of breaking up a rock or other materials using explosives. Blasting is often used in mining and construction projects to remove large sections of rock or soil. It can also be used to create holes for utility lines or other objects that need to be buried beneath the ground.
Why is trenching better than blasting?
Blasting involves using explosives to break up rock and soil, which can be dangerous and disruptive. Trenching is a much safer and quieter process, making it ideal for areas where blasting is not an option.
In addition, trenching is more precise than blasting, so it can be used to dig trenches that are very close to existing structures without damaging them.
What are safety concerns regarding excavation work?
There is always a risk of collapse when excavating, so it is important to be aware of your surroundings and make sure the walls of the trench are stable before entering it.
At what depth does a trench require shoring?
OSHA, the U.S. Occupational Safety and Health Administration, requires that a trench that is five feet deep or more must be shored to prevent collapse. Shoring involves placing supports, such as timbers or metal frames, along the sides of the trench.
Furthermore, any trench over 20 feet deep requires a shoring system designed by an engineer for the safety of everyone involved in the project.
What are the dangers of blasting during excavation?
The primary danger of blasting is the risk of injury or death from flying debris. In addition, blasting can cause damage to nearby buildings and structures, as well as create noise pollution.
What are things you should be looking at prior to excavating?
1. Make sure you have the proper permits and permissions in place before starting any work.
2. Conduct a thorough site assessment to identify any potential hazards, such as underground utilities or unstable ground.
3. Create a detailed excavation plan that takes into account the type of equipment you will be using and the amount of material you need to remove.
4. Be sure to stay aware of your surroundings at all times and never enter an excavation site without a qualified person present.
In conclusion, while blasting gets the job done, there are better, safer, and more controllable options when you need excavating work done for your project.
