First of all, let's start with those caissons,   which will be prefabricated on land.

，我们从那些沉箱开始，这些沉箱将在陆地上预制。

They placed layers of stone on top of the caisson as they dug.

This work was done in underwater chambers called " caissons."

这项是在水下的密闭舱室进行的， 这些舱室被称为“沉箱” 。

These caissons were used to build the bridge under the water.

这些沉箱用于在水下造桥梁。

But with extra troops required to do it right the caissons are not being used to limit the number of people interacting.

但由于需要额外的部队来执行任务，为了减少人们接触的次数，目前不再使用沉箱了。

Working conditions in these caissons were dismal and dangerous.

They sit in huge concrete  caissons that were prefabricated on land then dropped into trenches on the seabed.

Building on the rocky river bed involved the use of a largely untested technology: pneumatic caissons.

在多岩石的河床上造筑涉及使用一种基本上未经检验的技术：气动沉箱。

Anchors and winches are used  to position the caissons, which are ballasted with  water to keep them stable.

锚和绞盘用于定位沉箱，沉箱用水压载以保持稳定。

Barges armed with huge cranes were  then used to pick up the caissons and manoeuvre them to their resting place.

配备巨型起重机的驳船随后被用来搬运沉箱并将它们运到停放处。

OCEANIX, which is constructing an  entire floating city in South Korea, is placing everything on platforms  made from concrete caissons.
