Their design depends upon the nature of the embankment and does not depend upon the type or parts of the bridge. [ 1 ] The soil and fill supporting the roadway and approach embankment are retained by the wing walls, which can be at a right angle to the abutment or splayed at different angles.
The culvert is a highly intact example of the standard design for brick culverts on the Southern and Western Railway. The culvert follows the design approved by the Engineer in Chief for construction of the line, Abraham Fitzgibbon, in 1863 and comprises floors and sides of sandstone with an arched roof of bricks.

About 75m north of the wing-wall culvert is an extensive ashlar masonry retaining wall. The wall curves to cross a gully where a former bridge was located. The span of the bridge has now been infilled with a large diameter concrete pipe surrounded by cement mortared stone blocks probably deriving from nearby structures such as the wing-walled ...
Accidents from culvert failure can also occur if a culvert has not been adequately sized and a flood event overwhelms the culvert, or disrupts the road or railway above it. Ongoing culvert function without failure depends on proper design and engineering considerations being given to load, hydraulic flow, surrounding soil analysis, backfill and ...

Headwall and corrie lake Cwm Idwal. In physical geography and geology, the headwall of a glacial cirque is its highest cliff.The term has been more broadly used to describe similar geomorphic features of non-glacial origin consisting of a concave depression with convergent slopes typically of 65 percent or greater forming the upper end of a drainage valley.
The wings are longer than the ones on previous versions of that airplane—a design change that helps increase the craft’s overall fuel efficiency. NASA’s weird wing design could lead to ...
The size of the culverts (often concrete pipes) is usually selected to allow the water to flow below the roadway and provide a dry crossing surface for most of the year. During periods of high water flow (e.g. spring runoff or flash floods), water will flow over the top of the crossing, as the culverts are not large enough to carry these flood ...
