A gooseneck tunnel, an indentation in the floor structure, that meshes with the gooseneck on dedicated container semi-trailers, is a mandatory feature in the bottom structure of 1AAA and 1EEE (40- and 45-ft high-cube) containers, and optional but typical on standard height, forty-foot and longer containers.

Barrel, barrel-arched (cradle, wagon): A round roof like a barrel (tunnel) vault. Catenary: An arched roof in the form of a catenary curve. Arched roof, bow roof, [11] Gothic, Gothic arch, and ship's bottom roof. Historically also called a compass roof. [12] [13] Circular Bell roof (bell-shaped, ogee, Philibert de l'Orme roof): A bell-shaped roof.
A gooseneck is a semi-rigid, flexible joining element made from a coiled metal hose. Similar to its natural counterpart , it can be bent in almost any direction and remain in that position. [ 1 ] Areas of application for goosenecks are movable brackets for lights , magnifying glasses , microphones and other devices. [ 2 ]
PPI – the predecessor of the UIC gauges had the maximum dimensions 3.15 by 4.28 m (10 ft 4 in by 14 ft 1 in) with an almost round roof top. UIC A: The smallest (slightly larger than PPI gauge). [5] Maximum dimensions 3.15 by 4.32 m (10 ft 4 in by 14 ft 2 in). [6] UIC B: Sligtly larger than the UIC on the roff level. [5]
Gooseneck vent with check valve being repainted. A gooseneck (or goose neck) is a 180° pipe fitting at the top of a vertical pipe that prevents entry of water. Common implementations of goosenecks are ventilator piping or ducting for bathroom and kitchen exhaust fans, ship holds, landfill methane vent pipes, or any other piping implementation exposed to the weather where water ingress would ...
Hoophouses have existed at least since the 1940s, but they are much more commonly used with each passing decade, and their design continues to evolve. Because of the wide variety of constantly changing designs, in reality there is an entirely continuous spectrum from high tunnels through low tunnels to the simplest row covers, although they are ...
A barrel vault, also known as a tunnel vault, wagon vault or wagonhead vault, is an architectural element formed by the extrusion of a single curve (or pair of curves, in the case of a pointed barrel vault) along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design.
The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks , determines the ...
