Bottomcutting

Bottomcutting is a term used in the context of construction and excavation to describe a specific technique used to remove soil or rock from an area. It involves digging a small trench or cut at the foot of a slope or embankment to prevent or reduce the risk of erosion or instability.

The primary purpose of bottomcutting is to reduce the angle of the slope to a more stable level, thereby preventing soil or rock from sliding or falling. This is typically done in areas where the natural slope is too steep or unstable, posing a threat to nearby structures or infrastructure.

To execute a bottomcutting operation, a shallow trench is dug at the base of the slope, typically just below the level of the surrounding terrain. The excavated soil or rock is then removed and either dumped nearby or transported to a designated disposal area.

Important factors to consider when performing a bottomcutting operation include the type of soil or rock being excavated, the depth and angle of the slope, and the potential impact on nearby structures or the environment. In some cases, alternative techniques such as stabilization with geotextiles or soil grouting may be more effective or cost-efficient.

Bottomcutting is commonly employed in various settings, including road construction, tunneling, and mining. It can also be used to prevent landslides or erosion in sensitive ecosystems such as riverbanks or coastal areas. The technique requires careful planning and execution to ensure safety and minimize environmental damage.
