Everything about Pound Lock totally explained
A
pound lock is type of
lock that's used almost exclusively nowadays on
canals and
rivers. A pound lock has a chamber (the
pound) with
gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a
flash lock.
History
Pound locks may have been used in antiquity by the
Ptolemaic Greeks and the
Romans as indirect evidence suggests.
Pound locks were created in medieval
China during the
Song Dynasty (960–1279 AD). It was pioneered by the government official and engineer
Qiao Weiyo in 984, mentioned by the Chinese polymath scientist
Shen Kuo (1031–1095) in his book
Dream Pool Essays (published in 1088), and fully described in the
Chinese historical text Song Shi (compiled in 1345).
In medieval
Europe a type of pound lock was first built in 1373 at
Vreeswijk,
the Netherlands. This pound lock serviced many ships at once in a large
basin, yet the true pound lock (for example one for a small basin) came in 1396 with the one built at
Damme near
Bruges.
