Talk:Caisson (engineering)

Additional text for review

Moved from article for review here:

"there are many more types in caisson construction, amongst which the floating method is mostly used for shallow waters, The various parts of caisson, or full monolithic cassion is casted at land, and floated on barges, and then sunkun to the place, the ground on which the caisson is to be placed i s neatly dredged, and surface is made levelled, sinking can be accelerated by increasing self weight by adding sand in to the caisson,the main disadavantage can be , workers can not go to the bootom, working conditions are not dry, so quality of concrete should be neatly supervised, any obstacles coming beneath cant be seen , as compared to pnumatic caissions, chances of caisson disease are less, even labour requred is too less, chances of fatl accidents are to less, depth of foundations can ary upto 60 m." —Preceding unsigned comment added by 118.94.153.23 (talk • contribs) 18:14, May 28, 2009 (UTC)

Boat Lift Caissons Needs Work?

The section "Boat lift caissons" describes a canal lock system rather than a means of lifting a boat. I came here looking for the latter trying to learn more about the caissons used to lift the Costa Concordia as mentioned in a BBC article . The Costa Concordia article refers to these things as sponsons. Not sure what the right thing is. -- Cjensen (talk) 17:17, 17 September 2013 (UTC)

It means box, and is used in several ways. · · · Peter (Southwood) ^(talk): 14:03, 3 June 2018 (UTC)

History needed

This article needs a history section. When were caissons first used, and are they still used? If not, what methods of constructing underwater bridge foundations took the place of caissons? Also, there should be a discussion of working conditions for workers in caissons. Historically, this was considered horrible work. Did this ever change? —Anomalocaris (talk) 07:26, 3 June 2018 (UTC)

I don't have any references for history of caissons, but they are still used when needed. Hyperbaric working environments are also used in tunneling. They are avoided when reasonably practicable, as the decompression is a health hazard and costly in unproductive labour time, but the risks are now relatively low as the decompression schedules are well established and treatment is effective in the rare cases where decompression sickness occurs. The work is very much like mining. If you would consider working underground in a confined space, often wet, as horrible work then it would be. For others it is just a slightly different environment to do whatever work they do. If you find me suitable references I could write something up, but it is not on my priority list at present. · · · Peter (Southwood) ^(talk): 14:21, 3 June 2018 (UTC)

Air Lock Diving-Bell Plant

Hi, Caisson editors! I've added this as a see-also in order to be able to take an 'orphan' tag off a DYK on today's main page. I don't know enough about either subject to know where it would be more appropriately inserted, and I'm hoping someone here will be excited to discover this new article, which seems to certainly be worth mentioning in the Caisson article. --valereee (talk) 12:18, 14 June 2019 (UTC)

Wind turbines

An important use of caissons is for foundations used in offshore power generation, wind turbines, ocean current turbines and such. It seems like they should at least be mentioned. 212.100.0.229 (talk) 17:37, 21 February 2024 (UTC)

Schematic cross section is not clear

I don't understand why two structures appear but the text is "Schematic cross section of a presurized caisson" ~2025-41336-94 (talk) 09:44, 17 December 2025 (UTC)

That picture is showing a single structure, a huge cylinder. The reason it looks like two separate structures is the muck tube... That's a large vertical tube in the middle of the caisson. This cross sectional diagram goes right through the middle of the tube, so it gives the appearance of being two separate structures, left and right. If you imagine that muck tube is removed from the picture, then that will give you a better feeling for how the caisson looks. The picture could probably be improved by having the horizontal roof drawn through the muck tube, to let you know it's one solid roof. Noleander (talk) 15:27, 17 December 2025 (UTC)

Thank you! I understand it now. Still maybe other people will have my problem. I am not sure if the image should be modified or not. ~2025-41336-94 (talk) 08:18, 22 December 2025 (UTC)

You can replace the picture if you want. You can find the original picture in wiki Commons, you can download that picture to your computer, and modify it with any image editing application ... such as Inkscape. Then you can upload your new picture to Wiki Commons, and finally update this article to use your new picture. Noleander (talk) 11:23, 22 December 2025 (UTC)
