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 Figure 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, and in particular relates to a channel-shaped deep water tidal channel which is formed through dredging by using a 'two-way water control effect'. The technical proposal is to set continuous and straight diversion dikes or quays basically along a main stream direction of ebb and flow in a sea area where reverse current is given a priority so as to form the channel-shaped deep water tidal channel in a shape of 'horn shaped mouth gates at two ends and a long and narrow passage in the middle', wherein the channel forms a basin for shipping or a deep water channel; and the diversion dikes or the quays at the two sides of the channel form a port deep water coastline. The technical effects of the channel-shaped deep water tidal channel are as follows: the 'two-way water control effect' allows the overall sediment transport capacity of flow to be not less than the water sediment concentration; and the water depth of the basin for shipping and a sea-route water area after basic construction deepening is maintained for a long term; and the formed channel-shaped tidal channel has the advantages of straight coastline, long coastline, wide water area breadth, fast channel water area flow rate, deep water depth, small back silting, and good flow pattern. The 'two-way water control effect' is applied to regulating the depths of coastal port coastlines and sea routes.

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,...
