This is the Venice Lagoon with the three entrances: Lido, Malamocco, and Chioggia.

这是威尼斯泻湖的三个入口：丽都、马拉莫科和基奥吉亚。

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

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

Those manufactured on the Chioggia  side were constructed in a dry dock, which was filled with water, causing the  finished structures to become almost buoyant.

在 Chioggia 一侧制造的那些是在干船坞中建造的，该船坞充满了水， 导致完成的结构几乎可以漂浮。
