Question

Make sentence on railway embankment

Answer 1

A road, railway line or canal is 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 unacceptable change in level or detour to follow a contour. A cutting is used for the same purpose where the land is originally higher than required.

MaterialsEdit

Embankments are often constructed using material obtained from a cutting. Embankments need to be constructed using non-aerated and waterproofed, compacted (or entirely non-porous) material to provide adequate support to the formation and a long-term level surface with stability.

Answer 2

An embankment is a thick wall of earth that is built to carry a road or railway over an area of low ground, or to prevent water from a river or the sea from flooding the area.
