A chain pump is two large wheels, one above the other, connected by a chain. On the chain are hung buckets. Below the bottom wheel is a pool with the water source. As the wheel is turned, the buckets dip into the pool and pick up water. The chain then lifts them to the upper wheel, where the buckets are tipped and dumped into an upper pool. The chain then carries the empty buckets back down to be refilled.
The pool at the top of the gardens could then be released by gates into channels which acted as artificial streams to water the gardens. The pump wheel below was attached to a shaft and a handle. By turning the handle, slaves provided the power to run the contraption. An alternate method of getting the water to the top of the gardens might have been a screw pump.
This device looks like a trough with one end in the lower pool from which the water is taken with the other end overhanging an upper pool to which the water is being lifted. Fitting tightly into the trough is a long screw. As the screw is turned, water is caught between the blades of the screw and forced upwards.
When it reaches the top, it falls into the upper pool. Turning the screw can be done by a hand crank. A different design of screw pump mounts the screw inside a tube, which takes the place of the trough. In this case the tube and screw turn together to carry the water upward. Screw pumps are very efficient ways of moving water and a number of engineers have speculated that they were used in the Hanging Gardens. Strabo even makes a reference in his narrative of the garden that might be taken as a description of such a pump.
One problem with this theory, however, is that there seems to be little evidence that the screw pump was around before the Greek engineer Archimedes of Syracuse supposedly invented it around B.
Garden Construction Construction of the garden wasn't only complicated by getting the water up to the top, but also by having to avoid having the liquid ruining the foundations once it was released.
Since stone was difficult to get on the Mesopotamian plain, most of the architecture in Babel utilized brick.
The bricks were composed of clay mixed with chopped straw and baked in the sun. These were then joined with bitumen, a slimy substance, which acted as a mortar.
Unfortunately, because of the materials they were made of, the bricks quickly dissolved when soaked with water. For most buildings in Babel this wasn't a problem because rain was so rare. However, the gardens were continually exposed to irrigation and the foundation had to be protected. Diodorus Siculus, a Greek historian, stated that the platforms on which the garden stood consisted of huge slabs of stone otherwise unheard of in Babel , covered with layers of reed, asphalt and tiles.
Over this was put "a covering with sheets of lead, that the wet which drenched through the earth might not rot the foundation. Upon all these was laid earth of a convenient depth, sufficient for the growth of the greatest trees. When the soil was laid even and smooth, it was planted with all sorts of trees, which both for greatness and beauty might delight the spectators. Diodorus tells us they were about feet wide by feet long and more than 80 feet high.
Other accounts indicate the height was equal to the outer city walls, walls that Herodotus said were feet high. In any case the gardens were an amazing sight: A green, leafy, artificial mountain rising off the plain. It is thought that King Nebuchadnezzar built the Hanging Gardens to look like her homeland and make her less homesick. Question : Who were the gardens built for? Question : Can you visit the Hanging Gardens today?
Answer: No, they no longer exist. Nature and Science. Search Search for: Search. They are a set of gardens built thousands of years ago, in around B. She was from a place called Media, which today is in north-west Iran and south-east Turkey. Hanging Gardens of Babylon Facts The gardens were up to 75 feet high and it is thought that the plants tumbled down over a kind of pyramid-shaped stone structure.
The whole thing looked like a mountain! To make the gardens, the King had to build really deep foundations. Many believe that if the gardens did exist they would have been located south of Bagdad in Iraq.
Some historians and archaeologists believe that the gardens did exist and were destroyed by war and erosion. Some believe it was earthquakes that eventually devastated and destroyed the gardens. They grew from many different levels of terraces similar to balconies. It actually means overhanging instead of just hanging. A Greek historian named Diordorus Siculus described the gardens as being feet wide by feet long. He also said that the walls were more than 80 feet high. What he unearthed resembled what Diordorus Siculus had described.
This would have made it possible to irrigate the plants. Recent excavations have found traces of aqueducts near Nineveh, which would have supported such a garden.
