  2. Culvert - Wikipedia

    en.wikipedia.org/wiki/Culvert

    A culvert is a structure that channels water past an obstacle or to a subterranean waterway. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material. In the United Kingdom, the word can also be used for a longer artificially buried watercourse. [1]

  3. Low-water crossing - Wikipedia

    en.wikipedia.org/wiki/Low-water_crossing

    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 ...

  7. Tremie - Wikipedia

    en.wikipedia.org/wiki/Tremie

    The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4]The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water above it, thus limiting washing out of the cement content of the fresh concrete at the exposed upper surface.
