Seawall of shallow sea enclosed by channel dam road bridge

Abstract

The invention discloses a seawall of a shallow sea enclosed by a channel dam road bridge. The seawall of the shallow sea enclosed by the channel dam road bridge is characterized in that the seawall is formed by enclosing a plurality of channels which are arranged in parallel on sea-floor foundations; the road bridge is erected on the top part of each channel; each channel consists of dam side walls, a tide control embankment wall and a movable gate; each movable gate is arranged on the tide control embankment wall to constitute a bridge wall of a wave resistance revetment; the dam side walls are arranged on two sides of the bridge wall and fixedly connected with the bridge wall in an H-shaped form; and tide discharge way ports of small type hydroelectric generators are formed in the tide control embankment walls. In comparison with the prior art, the seawall of the shallow sea enclosed by the channel dam road bridge can divide tide and weaken wave, so that the impact damage of the sea tide to the seacoast can be effectively prevented or eliminated; particularly in a typhoon season, the damage decreasing effect is obvious; the stage difference between the rising tide and the falling tide can be retained and expanded for water discharge power generation; in such a way, the tidal potential energy of the shallow sea can be fully utilized; a water area within the seawall is an ideal fairway in which the breeding of marine products can be developed; two sides of the road bridge can be used as boat parking wharfs; and therefore, the utilization rate and the economic benefit of the seawall are improved.

Description

technical field [0001] The invention relates to the technical field of dikes and dams and hydraulic structures, in particular to a sea dike for enclosing shallow seas with trenches, dikes, roads and bridges. Background technique [0002] At present, the seawalls built along the coast are limited to blocking tides and waves to achieve the purpose of flood control and disaster prevention. Seawalls generally adopt a solid wall structure. Thick and heavy embankments have high requirements for the load-bearing foundation of the seawall, which has the disadvantages of large amount of building materials, high cost, single purpose, and only input but no output. [0003] On the coast, islands and sea reefs of our country, there are long and wide shallow sea areas and the high tide and ebb tide in the shallow sea area. In the long waters there are ideal coastal waterways, and in the wide shallow waters there are ideal shallow sea fisheries. The high tide and low tide that occur in ...
