Caisson (engineering) - Wikipedia
In geotechnical engineering, a caisson (/ ˈkeɪsən, - sɒn /; 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.

Caisson vs. Cofferdam: What’s the Difference? - HSI Services Inc
2020年3月6日 · Both caissons and cofferdams are watertight structures that can be used in the construction of submerged water areas. The difference, however, lies within the scope of the project. Caissons are permanent structures found in the initial design construction, whereas cofferdams are temporary structures installed for necessary repairs or maintenance.
Dewatering 101: Complete Guide to Cofferdams - HSI Services Inc
2020年3月13日 · Caissons, cofferdams, inflatable water dams–what are these terms and how do they relate to your construction project? To stay ahead in your construction progress and successfully complete your work, having a dewatering solution is key. Get the inside look of one of the best inventions in water construction with our guide to cofferdams.
The most common methods for dewatering include sumps, wells and wellpoints. Sumps provide localized, very shallow dewatering (less than 3 feet) and consist of pumping from perforated drums or casings in a gravel-filled backhoe pit. Sumps work best in tight, fine grained soils, or very coarse, bouldery deposits.
caisson in the dewatering construction of urban infrastructure can be avoided because of the less excavation and impact on the adjacent buildings. The open caisson structure is mainly named after its construction method. In a word, it is an underground structure built by sinking to a certain underground elevation by some means.
Cofferdams are temporary enclosures to keep out water and soil so as to permit dewatering and construction of the permanent facility (structure) in the dry. A cofferdam involves the interaction of the structure, soil, and water. The loads imposed include the hydrostatic forces of the water, as well as the dynamic forces due to currents and waves.
Understanding the Fundamentals of Caisson Drilling for Engineers
Caisson drilling is a method used in engineering to create deep foundation structures. It involves drilling cylindrical shafts into the ground and filling them with concrete or other structural materials. How does caisson drilling work? Caisson drilling works …
Cofferdams: Uses, Types, Design, and Construction - Structville
2022年11月7日 · A cofferdam is a structure used to keep soil and/or water out of an area where construction work must be done to a depth below the surface. The effects of water penetration must always be taken into consideration in any calculations, even though the total exclusion of water is frequently unnecessary and occasionally not practicable.
Water Filled Temporary Cofferdam Barriers For Construction
AquaDam is a water-filled cofferdam perfect for providing flood control on construction sites. Its clever design features two water-tight polyethylene tubes enclosed within a woven outer sleeve, forming a robust but temporary water barrier.
Eiffel 101: 6 Types of Caissons | Eiffel Trading
Caissons are concrete, wood, or steel structures utilized for the purpose of dewatering as the foundations of bridges, ports, piers, and quay walls are constructed. Generally, caissons are permanent structures and become a part of the final product of deep foundations.
