What is open area excavation?


Open area excavation generally includes the excavation of an entire development footprint or substantial sections known to contain intact archaeology. Such excavation also includes surveying to map the exposed elements and best practice recording of all resident structures and deposits.

Keeping this in consideration, what are the three methods of excavation?

There are number of excavation methods which are used for deep foundation construction such as full open cut method, bracing excavation, anchored excavation, island excavation methods,zoned excavation, top down construction methods etc. These excavation techniques are discussed.

Furthermore, what are the types of excavation? Excavation by Material

  • Topsoil Excavation. As the name suggests, this type of excavation involves the removal of the exposed or the topmost area of the earth’s surface.
  • Rock Excavation.
  • Muck Excavation.
  • Earth Excavation.
  • Cut and Fill Excavation.
  • Trench Excavation.
  • Basement Excavation.
  • Dredging.

Consequently, what is the purpose of excavation?

Excavation is the process of moving earth, rock or other materials with tools, equipment or explosives. Excavation is used in construction to create building foundations, reservoirs and roads. Some of the different processes used in excavation include trenching, digging, dredging and site development.

What excavation reveals?

In archaeology, excavation is the exposure, processing and recording of archaeological remains. An excavation site or “dig” is a site being studied.

What is the fastest way to dig a trench?

  1. Loosen hard soil using a pick axe.
  2. Define the sides of the trench using the point of your shovel.
  3. Pull soil out of the bottom of the trench with a grub hoe once it becomes too deep to use a shovel.
  4. Place all the soil that you pull out of the trench on one side.

What are archaeological methods?

The archaeological method helps scientists uncover artifacts responsibly. When archaeologists begin the excavation, they don’t just start plowing shovels into the ground. First they create a grid system to help record where objects are unearthed. Then they gently start moving the earth one tiny trowel full at a time.

What is the difference between horizontal and vertical excavation?

In vertical excavation, the archeologist may use test units to identify and/or remove strata. In horizontal excavation, the archeologist may plow strips along the surface of the site to expose any objects lying near the surface.

How do you dig deep trenches?

The drainage spade is made for digging shallow rough trenches up to about 12 inches deep and 5 inches wide. The narrow round point is great for penetrating sod, hard soil, and dirt with rocks. The long length of the blade makes it easy to dig shallow trenches for drainage and utility lines.

What is excavation in safety?

General Trenching and Excavation Rules

Keep heavy equipment away from trench edges. Keep surcharge loads at least 2 feet (0.6 meters) from trench edges. Know where underground utilities are located. Test for low oxygen, hazardous fumes and toxic gases. Inspect trenches at the start of each shift.

How deep can excavator dig?

A 4,000- to 6,000-pound mini excavator can dig a 10-foot-deep hole. Larger 10,000- to 12,000-pound mini excavators allow dig depths as deep as 14 feet.

Why is recording necessary during and after excavation?

It is often (and correctly) said that excavation is also destruction. Careful, consistent, and accurate recording is necessary in any archaeological undertaking; it is essential for archaeological interpretation and it is one of the basic tasks of site conservation and preservation.

What is the synonym of excavation?

Synonyms: barb, dig, jab, slam, shot, shaft, archeological site, digging, jibe, gibe, mining. dig, excavation, archeological site(noun) the site of an archeological exploration. “they set up camp next to the dig”

What are archaeological techniques?

The first step in an archaeological excavation is surveying the area. This can be done either with remote sensing or direct visual observation. Archaeologists conducting a survey. Archaeologists also use non-invasive techniques to survey sites known as remote sensing.

Is archeology a science?

Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities.

What are the hazards of excavation?

The hazards and risks are usually:

The undermining of nearby structures causing their collapse into the excavation. Damage to underground services during excavation work causing electrocution, explosion, gas escape, flooding etc. Ingress of water causing flooding.

How do you make excavations safe?

10 Excavation Safety Tips
  1. Inspect trenches daily before work begins.
  2. Check weather conditions before work, be mindful of rain and storms.
  3. Keep heavy equipment away from trench edges.
  4. Be mindful of the location of utilities underground.
  5. Always wear proper protective equipment.
  6. Don’t work beneath raised loads.

Why is Archaeology important today?

Why is Archaeology Important? Archaeology provides us with the opportunity to learn about past cultures through the study of artifacts, animal bones and sometimes human bones. Studying these artifacts helps to provide us with some insight about what life was like for people who left behind no written record.

What is Isarchaeology?

Archaeology is the study of the human past. Archaeologists use the material remains of human activities to reconstruct the behaviors and beliefs of prehistoric peoples. One of the most unique features of the science of archaeology is its ability to study human behavior over spans of hundreds or even thousands of years.

What is footing in construction?

Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation and prevent settling. A footing is placed below the frost line and then the walls are added on top.

What is construction grade?

Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.

What is cut and fill in construction?

In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor.
