Method for improving tide coastline dock ship grade and semi-submersible harbor basin

Abstract

The invention discloses a method for improving ship rank of a tidal bank-line wharf and a semi-submerged harbor pool. The method is that: an openable and closable harbor pool similar to a ship lock is designed and constructed at the front edge of the tidal bank-line wharf and is combined with the wharf; after a cargo ship drives into a berth in the harbor pool through a gate of the harbor pool at high tide level, the ship lock is closed, the wharf begins to work; during the ebb-tide, the water level of the harbor pool is decreased to the designed water level of the harbor pool through a water overflow and discharge channel, then a harbor pool water supply system remains the water depth of the harbor pool; when the loading or unloading of the cargo ship is finished, the gate of the harbor pool is opened when the high tide level appears to ensure that the cargo ship drives away the operation harbor pool; the method of the invention adopts a semi-submerged harbor pool which consists of an enclosed pool wall, a harbor pool gate for ship in / out, a water overflow and discharge channel of the harbor pool, a harbor pool water supply system and a harbor pool operation control system; at least one pool wall is the front edge of the wharf, and at least one side is the gate of the harbor pool. The invention has the advantages of: simple and reliable method, small investment and quick effect, can effectively take advantage of the prior tidal wharf to retrofit or construct, can effectively improve the ship rank of the tidal bank-line wharf, has high resource utilization rate and so on.

Description

Technical field [0001] The invention relates to a method capable of improving the ship level of a tidal shoreline wharf and a related semi-submersible harbor basin, which can be widely used in the transformation and upgrading of newly built wharves and old wharves with large tidal range. Background technique [0002] For wharves on tidal shorelines, there is generally a problem that the ship grades are generally low. For example, the wharves built on both sides of the tidal estuary are affected by the tidal water level. If a larger tonnage is berthed at this tidal shoreline wharf When the tide level drops to a low level, large ships will run aground and cannot perform normal loading and unloading operations. Therefore, the level of the wharf ship has a great relationship with the water level of the shoreline when the wharf is constructed; although the tidal water level can meet the requirements for berthing and operation of large ships at high water levels, once the tide water le...

Problems solved by technology

[0002] For wharves on the tidal coastline, there is generally a problem that the ship level is generally low. For example, the wharf built on both sides of the tidal estuary, the size of the ship is affected by the tidal water level. When the tidal water level drops to low water level, large ships will run aground and cannot carry out normal loading and unloading operations

Therefore, the level of wharf ships has a great relationship with the water level of the shoreline when the wharf is built; although the tidal water level can meet the requirements of berthing and operation of large ships at high water levels, once the tidal water level drops to low water levels, it cannot Moor large ships and carry out port operations
