In civil engineering, a headwall is a small retaining wall placed at the inlet or outlet of a stormwater pipe or culvert. [2] In medicine, a headwall is the wall at the head end of a hospital bedspace. The bed abuts this headwall perpendicularly, which is furnished with equipment such as regulators for supplemental oxygen, regulators for ...
Steel corrugated culvert with a drop on the exhaust end, northern Vermont. Culverts can be constructed of a variety of materials including cast-in-place or precast concrete (reinforced or non-reinforced), galvanized steel, aluminum, or plastic (typically high-density polyethylene). Two or more materials may be combined to form composite ...
The vertical hard basin drop structure, also called a dissipation wall, is the basic type of drop structure.The vertical hard basin drop consists of a vertical cutoff wall, usually built of concrete, that is usually laid perpendicular to the stream flow, and an impact basin, not unlike a stream pool, to catch the discharged water.
Successful pipe designs (e.g. Flexible Pond Leveler, Castor Master, Clemson Pond Leveler) achieve this by protecting the intake end of the pipe with a cylindrical fence enclosure. A beaver swimming along the outside of the fence enclosure is unable to hear or feel the flow of water into the pipe and cannot reach it to block it.
A basement wall is thus one kind of retaining wall; however, the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. [2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
Slurry wall design is undertaken based on bending moment and shear envelope obtained from the stress analysis. In the design of such underground walls, width of the unit is considered as one meter, and the wall is analyzed under plane strain condition. Since the length-to-width ratio of excavations is generally large, plane strain conditions ...
Wikisource has original text related to this article: End Poem (full text) The end credits of the video game Minecraft include a written work by the Irish writer Julian Gough, conventionally called the End Poem, which is the only narrative text in the mostly unstructured sandbox game. Minecraft's creator Markus "Notch" Persson did not have an ending to the game up until a month before launch ...
The term may also be used for the "end walls" of bulkhead flatcars. Mechanically, a partition or panel through which connectors pass, or a connector designed to pass through a partition. In architecture the term is frequently used to denote any boxed in beam or other downstand from a ceiling and by extension even the vertical downstand face of ...
