Gate bulwark capable of adjusting water flow

The invention discloses a gate bulwark capable of adjusting water flow. The gate bulwark capable of adjusting water flow comprises a bulwark structure unit and is characterized in that the bulwark structure unit comprises a bulwark body and a top prefabricated slab arranged above the bulwark body, a turning device is arranged on the top prefabricated slab, two insertion holes I are formed in the top prefabricated slab, a concrete prefabricated slab gate is arranged on the inner side of the bulwark body, a base plate is arranged at the bottom of the bulwark body, and the concrete prefabricated slab gate is connected with the base plate through an auxiliary rotating shaft. The gate bulwark has the advantages of preventing wave and silt. Under the daily sea conditions, a motor is started to turn and open the gate, the gate bulwark serves as a breakwater at the moment and can resist the influence of a part of small waves and meanwhile does not cause severe in-harbor silting. When strong wave comes, the gate can be closed, the gate bulwark serves as a hollow embankment the wave eliminating effect can be effectively played, and the stability of a water area within a harbor is ensured to facilitate normal berthing and operation of ships.
