A trench is a type of excavation or depression in the ground that is generally deeper than it is wide (as opposed to a swale or a bar ditch), and narrow compared with its length (as opposed to a simple hole or pit). [1] In geology, trenches result from erosion by rivers or by geological movement of tectonic plates.
An excavation lake (also a flooded gravel pit) is an artificial lake, which usually has its origins in the excavation of gravel or sand for construction materials or in some other kind of surface mining. In many cases, the excavation holes are landscaped according to the land restoration required by law.
Excavation may be classified by type of material: [1]: 13.1 Topsoil excavation; Earth excavation; Rock excavation; Muck excavation – this usually contains excess water and unsuitable soil; Unclassified excavation – this is any combination of material types; Excavation may be classified by the purpose: [1]: 13.1, 13.2
Construction along Ontario Highway 401, widening the road from six to twelve travel lanes. A construction project is a complex net of construction contracts and other legal obligations, each of which all parties must carefully consider. A contract is the exchange of a set of obligations between two or more parties, and provides structures to ...
A well is an excavation or structure created on the earth by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump, or using containers, such as buckets that are raised mechanically or ...
Archaeological excavation is an unrepeatable process, since the same area of the ground cannot be excavated twice. [24] Thus, archaeology is often known as a destructive science, where you must destroy the original evidence in order to make observations.
A crawler excavator, also known as a track-type excavator or tracked excavator, is a type of heavy construction equipment primarily used for excavation and earthmoving tasks. It is characterized by its tracked undercarriage, which provides superior mobility and traction compared to wheeled excavators, especially in soft, uneven, or unstable ...
Engineering geology is the application of geology to engineering study for the purpose of assuring that the geological factors regarding the location, design, construction, operation and maintenance of engineering works are recognized and accounted for. [1]
