Principle of lock in Jinan moat

The lock of Jinan moat adopts the connector principle. The principle of communication means that several containers with interconnected bottoms are filled with the same liquid. When the liquid does not flow, the liquid level of each container in the communication device is always kept at the same level. The ship lock uses the connector principle to make the ship sail safely between the upstream and downstream or between the two banks.
