Working conditions in these caissons were dismal and dangerous.

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

事实证明，些沉箱中工作是非常危险的。

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

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

可能就是数百名布鲁克林大桥上工作的人最终患上沉箱病的原因。

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，些沉箱将陆地上预制。

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

Across all three sites, when it came to  lowering the caissons, hydraulic dampers in each corner helped to absorb the force of  these massive structures hitting the seabed.

所有三个地点，当需要降低沉箱时，每个角落的液压阻尼器都有助于吸收些巨大结构撞击海床的力量。

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.

大门的工作方式可能很聪明，但从建筑的角度来看，可能最令人印象深刻的是巨大的房屋或沉箱。
