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。

Here and there in the road and fields lay buckles and bits of harness leather, canteens flattened by hooves and caisson wheels, buttons, blue caps, worn socks, bits of bloody rags, all the litter left by the marching army.

路上或田里，到处可以看到带扣，马嚼子和马鞍的碎皮件，还有踏遍的水壶、弹药箱的轮子、钮扣、军帽、破袜子和血污的破布，以及行军时丢下的种种七零八碎的东西。

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

这项工作是水下的室中进行的， 这些室被称为“沉箱” 。

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

OCEANIX 正韩国建造一座完的漂浮城市，它把所有东西都放由混凝土沉箱制成的平台上。

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

石的河床上建造建筑涉及使用一种基本上未经检验的技术：气动沉箱。

Working conditions in these caissons were dismal and dangerous.

这些沉箱中的工作条件恶劣且危险。

This meant that the work had to stop and the caissons had to be fixed in order to continue the work, and so, like most construction projects, it took much longer than they had planned.

这意味着工作不得不暂停，沉箱必须得到修复才能继续施工，因此，像大数建筑工程一样，实际耗时比计划的要长得。

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

所有四个障碍处还有两个肩部沉箱，将房屋连接到大陆。

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

他们边挖边沉箱上面放上一层层石头。

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

事实证明，这些沉箱中工作非常危险。

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。

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

这些沉箱用于水下建造桥梁。

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，另一艘船为沉箱奠定基础之前，施工前的疏浚工作现场进行。

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

它将由充满沙子的混凝土沉箱制成。

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

这可能就是为什么布鲁克林大桥工作的数百人最终患上了沉箱病。

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

他们坐巨大的混凝土沉箱中，这些沉箱是陆地上预制的，然后投入海床上的战壕中。

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

Chioggia 和 Malamocco，使用了不同的方法将沉箱放入水中。

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这些巨大结构撞击海床的力量。

These pictures show that it will probably be  either made of watertight caissons placed on the seabed and surrounded by seawalls, or  built up with sand as an artificial island.

这些图片显示，它可能是由放置海床上并被海堤包围的防水沉箱制成，或者是用沙子建成的人工岛。

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，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，从岛的南侧开始。
