Ship lock, refers to a kind of "navigation building". In natural rivers, because of the regulation of flow, canalization navigation and the restriction of topographic conditions and water surface gradient on the canal, a step-shaped vertical section is required to form a concentrated water surface drop. The vessel must be moved directly through the drop by means of a special navigable building. Modern navigable buildings are most commonly used in ship locks. It is a box-shaped structure, consisting of upstream and downstream navigation channels and upstream and downstream gate head connecting chambers. The lock chamber is a chamber-shaped chamber for berthing a ship (or a fleet), and the water level in the lock chamber is adjusted by filling water or draining water in the lock chamber, so that the ship vertically ascends and descends between upstream and downstream water levels, and the water level difference of a concentrated channel is passed. When boats and ships went upstream by the low reaches, indoor water level falls to flushing with the low reaches water level, then opens the gate of low reaches lock head, and the lock room is gone into to the ship, closes the gate, and the watering is waited that the water level rises to flush the back with the upper reaches water level, opens the lock head gate of upper reaches, and the ship can go out the floodgate and navigate to the upper reaches through upper reaches approach channel. When the ship runs from upstream to downstream, the brake-passing operation procedure is opposite to the brake-passing operation procedure.
