Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site .
In civil engineering a shaft is an underground vertical or inclined passageway. Shafts are often entered through a manhole and closed by a manhole cover. They are constructed for a number of reasons including: For the construction of a tunnel; For ventilation of a tunnel or underground structure, aka ventilation shaft
A common need in engineering drawings is to instruct the user to do activity X in accordance with technical standard Y. For example, "Weld all subassemblies IAW AWS XYZ.123" means "Weld all subassemblies in accordance with American Welding Society standard number XYZ.123" (the number is hypothetical in this example). The word "per" is ...
Suction line (#3) is an intake line for the mud pump to draw drilling fluid from the mud tanks. Swivel (#18) is the top end of the kelly that allows the rotation of the drill string without twisting the block. Traveling block (#11) is the moving end of the block and tackle. Together, they give a significant mechanical advantage for lifting.
For the third time in the year, Venus will be the foundation for a planetary alignment, as it shines with Jupiter and the crescent moon before sunrise on Tuesday, Aug. 19. The trio will be easy to ...
Shallow foundations of a house versus the deep foundations of a skyscraper. Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground.
The actor went on to ask the villainous character if he enjoyed Carrey’s portrayal. "You know, they brought me in a couple days to do some consulting," he answered with a wink, adding that he ...
