An embankment is a raised wall, bank or mound made of earth or stones, that are used to hold back water or carry a roadway. A road , railway line , or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain , the alternatives being either to have an ...
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
Digging, also referred to as excavation, is the process of using some implement such as claws, hands, manual tools or heavy equipment, to remove material from a solid surface, usually soil, sand or rock on the surface of Earth.
Traverse: an earthen embankment, the same height as the parapet, built across the terreplein to prevent it being swept by enfilade fire. Casemate: a vaulted chamber built inside the rampart for protected accommodation or storage, but sometimes pierced by an embrasure at the front for a gun to fire through.
This may be initiated by either monotonic loading (i.e., a single, sudden occurrence of a change in stress – examples include an increase in load on an embankment or sudden loss of toe support) or cyclic loading (i.e., repeated changes in stress condition – examples include wave loading or earthquake shaking). In both cases a soil in a ...
Ash ponds are generally formed using a ring embankment to enclose the disposal site. The embankments are designed using similar design parameters as embankment dams, including zoned construction with clay cores. The design process is primarily focused on handling seepage and ensuring slope stability.
The driver in the Volvo was trapped inside while the other vehicle continued down an embankment. Fire crews removed a man from a vehicle following a two-car collision on a Fresno, California ...
In trench warfare, soldiers occupy trenches to protect them against weapons fire and artillery. Trenches are dug using manual tools such as shovel and pickaxe or heavy equipment such as backhoe, trencher, and excavator. For deep trenches, the instability of steep earthen walls requires engineering and safety techniques such as shoring.
