Problems solved by technology

Therefore, the inland waterway regulation technology and the tidal estuary channel regulation technology cannot be used to control the shoreline water depth and channel water depth of coastal ports.
[0005] To sum up, in the field of water transport engineering, there is still a lack of regulation methods suitable for the water depth of the port coastline and waterway when the sediment concentration in the entire sea area is large.

Embodiment 1

[0038] see figure 1 , figure 2, in the sea area 2 where the tidal current is mainly reciprocating, on both lateral sides of the harbor waters or channel waters, one side relies on the land area 1 or natural island 1, and the other side is in the sea area 2, basically following the main trend of the ebb tide 3, Continuous and straight diversion dikes or bank walls 5, 6, 7 are set in the main direction of rising tide 4, and tidal channels are formed between diversion dikes or bank walls 5, 6, 7 on both sides, and the tidal channels are divided into channel entrance sections in the longitudinal direction A9, channel inner section 8 and channel opening door section B10, the channel width of channel inner section 8 is basically the same, the channel width of channel opening door section A9, channel opening door section B10 is from channel inner section 8 to channel opening door Gradually enlarged, in the shape of "flare-shaped entrances at both ends, and a narrow and long channe...

Embodiment 2

[0040] see image 3 , figure 2 , on the basis of Embodiment 1, the artificial island bank 13 is set to form the artificial island 17 as the land area of ​​the port, and the diversion dikes or banks 5, 6, 7 on both sides of the strait-shaped deep-water tidal channel are used as the deep-water shoreline of the port, and pass The connecting bridge 16 connects the land area 1 or the natural island 1 and the artificial island 17 .

Embodiment 3

[0042] see Figure 4 , figure 2 , in the sea area 2 where the tidal current is mainly reciprocating, on the lateral sides of the harbor waters or channel waters, relying on natural islands 1 or directly in the sea area 2, basically follow the main direction of the ebb tide 3 and the main direction of the rising tide 4 to set continuous and parallel Straight diversion dikes or bank walls 5, 6, 7 form an artificial island 17, and a tidal channel is formed between diversion dikes or bank walls 5, 6, 7 on both sides. The inner section 8 and the passage door section B 10, the passage width of the passage inner section 8 is basically the same, the passage width of the passage opening door section A 9 and the passage opening door section B 10 gradually enlarges from the passage inner section 8 to the passage opening door, showing The shape of "trumpet-shaped entrances at both ends, narrow and long passage in the middle", thus forming a strait-shaped deep-water tidal passage in the ...

Abstract

The invention belongs to the field of marine traffic engineering, in particular to a strait deepwater tide channel regulated and formed by using bidirectional beam water effect. The technical scheme is achieved as follows: continuous and straight guide dikes or guaywalls are arranged basically along the main flow direction of flooding and ebbing tide in a sea area by mainly taking reciprocating flow as tidal current so as to form the strait deepwater tide channel with two ends having broadening doors and middle being a narrow channel, the channel forms an in-port water area or deepwater route, and the continuous and straight guide dikes or guaywalls at two sides of the channel form a port deepwater shoreline. The invention has the advantages that the bidirectional beam water effect leads the total sand-holding capacity of water flow not to be less than the sand content of a water body, water depth is maintained for a long time after foundations of the in-port water area and the router water area are deepened; the formed strait tide channel has straight and long shoreline, wide water area, high water area flow velocity of the channel, big water depth, small back-silting and good fluid state. The invention is used for regulating the coastal harbor shoreline water depth and the route water depth.

Description

Technical field: [0001] The invention belongs to the field of waterway engineering, and in particular relates to a strait-shaped deep-water tidal channel as a deep-water coastline and a deep-water channel, which is formed by using the "two-way water beam effect" to regulate the water depth of the shoreline and waterway of a coastal port. Background technique: [0002] Shoreline water depth and waterway water depth are one of the basic and key conditions for the construction of coastal port waterways. With the continuous development of international and domestic trade, the development of international and domestic shipping presents a trend of large-scale ships, trunk routes, and deep-water ports, and the requirements for coastline water depth and waterway water depth of coastal ports are getting higher and higher. Although coastal ports continue to shift to deep-water areas, due to the limited natural water depth along the coastline and the natural water depth of the channel,...
