كيف يتم بناء أعمدة الجسور في وسط البحر؟ السر الهندسي الذي لا يعرفه أحد

How are bridge piers built in the middle of the sea, surrounded by water on all sides? In this video, we reveal the engineering secret used to build bridges over seas and oceans: the caisson technique, which allows for the construction of strong underwater foundations. If you've ever wondered how bridges are built over the sea, or how workers operate underwater during construction, this video will reveal the entire process in a simple and engaging way.
