At Chioggia and Malamocco different methods  were used to launch the caissons into the water.

在 Chioggia 和 Malamocco，使用了不同方法将沉箱放入水中。

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

首先，让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.

他们边挖边在沉箱上面放上一层层石头。

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

这项工作是在水下密闭舱室中进行， 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建造桥梁。

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

但由于需要额外部队来行任务，为了减少人们接触，目前不再使用沉箱了。

Working conditions in these caissons were dismal and dangerous.

这些沉箱中工作条件恶劣且危险。

As it turns out, working in these caissons was very dangerous.

事实证明，在这些沉箱中工作非常危险。

There are also two shoulder  caissons at all four barriers, which connect the housings to the mainland.

在所有四个障碍处还有两个肩部沉箱，将房屋连接到大陆。

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

他们坐在巨大混凝土沉箱中，这些沉箱是在陆地上预制，然后投入海床上战壕中。

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

在多岩石河床上建造建筑涉及使用一种基本上未经检验技术：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.

OCEANIX 正在韩国建造一座完整漂浮城市，它把所有东西都放在由混凝土沉箱制成平台上。

It'll be made from concrete caissons filled  with sand.

它将由充满沙子混凝土沉箱制成。

This is probably why hundreds of people who worked on the Brooklyn Bridge eventually became sick with caisson disease.

这可能就是为什么在布鲁克林大桥工作百人最终患上了沉箱病。

A high concrete wall will then be built on top of the caissons to protect the island  from strong waves, wind and flooding.

然后将在沉箱顶部建造一堵高高混凝土墙，以保护该岛免受巨浪、风和洪水侵袭。

Anyway, after Simon has finished prepping the  seabed, those caissons are transported over by tugboat and lowered, starting  at the south side of the island.

总之，在西蒙完成海床准备工作后，那些沉箱会被拖船运过来并放下，从岛南侧开始。

The way the gates work may be clever, but  it's the enormous housings, or caissons, that are perhaps most impressive  from a construction point of view.

大门工作方式可能很聪明，但从建筑角度来看，可能最令人印象深刻是巨大房屋或沉箱。

Meanwhile, pre-construction dredging gets  underway at the site location, before another ship lays the foundations for the caissons  to lie on around the perimeter of the island.

与此同时，在另一艘船为沉箱奠定基础之前，施工前疏浚工作在现场进行。
