An excavation is a process that involves the removal of materials to form an elevated section of land. This can be done before an engineering project starts or for building purposes. There are a number of different types of excavations. They all serve specific purposes and require different techniques to be applied. Some are underground and some are above ground. Each type of excavation requires specialized equipment. Regardless of the type of excavation you have, there are a few things you should know to help you protect your employees and keep your construction site safe.
Underground excavation is often performed for utilities. It can include tunnels, pipes, and shafts. These are built for transportation and other passages. Aside from the specialized equipment, excavations are conducted with additional precautions.
What Are the 3 Types of Excavation?
Rock excavation can be one of the most difficult types of excavation. Rock is not stable and can be difficult to remove. Special equipment and explosives are needed. Blasting and drilling are also used in rock excavation septic install. While these methods may be used, the rock must be removed in an orderly manner. If the rock is too hard to break, it can create a barrier for construction projects.
Soil excavation is another type of excavation. Essentially, this type of excavation involves the removal of the soil layer below the topsoil. The resulting material can be used to build a structure’s foundation or drainage ditches. Depending on the situation, the materials can be used for fill, grading, or mixing with concrete.
Muck excavation is a similar procedure to that of soil excavation. However, muck is typically a mix of water and soil. During the process, muck is removed from the excavation site and spread to dry. Large excavation vehicles can be used to spread the muck.
Another type of excavation is roadway excavation. Roadways are usually constructed using this method. During this process, materials are used to create embankments and clear the way for roadways. Using this technique, storm drain pipes are installed under roadways. In addition, storm drains are also placed along the sides of a road to alleviate stagnation and flooding.
Muck can also be categorized as an unclassified type of excavation. Because this category is unspecified, it can be more difficult to determine what kind of material has been removed. Sometimes, the soil is mixed with other materials, making it difficult to tell what the original material was. For this reason, a physical test is required. You may find a ribbon test, penetrometer, or thumb test.
Underwater excavation is a challenging procedure. Although a professional can ensure the proper foundation for the construction project, underwater sediments can pose hurdles.
Topsoil excavation is the removal of the topmost layer of dirt and vegetation. It is done to remove any materials that might cause a building to sink. Usually, the topsoil is cleared before the foundation of a building is laid. Depending on the needs of the job, you may need to drill into the rock to clear the surface.
