Gate type seawall

Abstract

The invention relates to ocean engineering and discloses a gate type seawall. The gate type seawall comprises a plurality of seawall body structural units (12), wherein each of the seawall body structural unit (12) comprises a pile foundation (1) arranged underwater and a truss (3) arranged above the pile foundation (1), the truss (3) is provided with a support (7) wherein a rotating shaft (6) is arranged, and a gate (5) is arranged on the rotating shaft (6) and is controlled to open and close through a crane (10). The gate type seawall can give consideration to advantages of a solid dyke and a hollowed dyke; the gate is in an opened state under a daily sea state, the gate type seawall is equivalent to the hollowed dyke, can block part of daily moderate seas, has little influence to a tidal current field and cannot increase sediment deposition in ports; and the gate is closed during an extreme sea state, the gate type seawall is equivalent to the solid dyke, can effectively block rough seas generated during the extreme sea state from entering into a port region, thereby ensuring the safety of ships and personnel in the ports.

Description

technical field [0001] The invention relates to ocean engineering, in particular to a gate type breakwater. Background technique [0002] The breakwater is a water structure built to block the impact of waves, protect the harbor basin, maintain a stable water surface to protect the port from bad weather, and allow ships to berth and operate safely. Commonly used breakwaters include solid breakwaters (referred to as solid dikes) and permeable breakwaters (referred to as permeable dikes). [0003] Solid dikes are more effective against waves because waves can hardly penetrate solid dikes. However, solid dikes block the tidal current very obviously, and have great changes in the tidal current field near the port area. In sea areas with high sediment content, sediment deposition in the port area is often caused, which makes the water depth in the port area continuously decrease and increases the port area. dredging volume. For some small ports with poor economic benefits, suc...

Problems solved by technology

However, waves can pass through the dike, which is effective in blocking small waves in daily sea conditions. However, in extreme sea conditions, large waves can easily enter the port through the embankment, making the wave condition in the port area worse, causing damage to ships and breaking of cables and other serious accidents, even endangering the life safety of the crew
