The outer submerged dike 11 is an outermost barrier of the whole protection unit, is used for separating the open sea from a project implementation area, is a cofferdam with the top height lower than the average sea level, and is mainly designed in such a way that the lower half part of the cofferdam is designed into a watertight structure and is used for preventing high-silt content seawater of a seawater low layer from entering the artificial bay 21 and ensuring that a water body of the artificial bay 21 does not flow out of the sea so as to form a stable water surface with a certain height in the artificial bay 21; the upper half part of the outer submerged dike is of a water permeable structure, such as a concrete fish reef structure and a shellfish reef structure, and is used for inhabiting organisms such as fish and meeting the function of water body exchange;
the inner submerged dike 12 is positioned at the inner side of the outer submerged dike 11, is parallel to the outer submerged dike 11 and forms an artificial inner bay 21 together with the outer submerged dike 11; meanwhile, the inner submerged dike 12 is parallel to the beach shoulder line of the artificial beach 15 and is positioned at the toe position of the artificial beach to protect the stability of the beach and prevent sand of the beach from flowing out into the artificial inner bay 21; the top elevation of the artificial sand beach is slightly higher than the elevation of the toe of the artificial sand beach, and the slopes on the two sides are relatively slow, so that personnel can smoothly enter the artificial bay 21; the construction materials can adopt a form of a semi-permeable and waterproof structure, and are not suitable for adopting permeable structures such as fish reefs, shellfish reefs and the like to prevent sand beach loss, and are not suitable for structures with tips and bulges to prevent people from treading;
in a further optimized scheme, an outer sludge discharge channel 13 is arranged on the outer side of the outer submerged dike 11.
The outer sludge discharge channel 13 is positioned at the outer side of the outer submerged dike 11, is parallel to the outer submerged dike 11, is an inverted triangular or inverted trapezoidal groove which is manually excavated and is lower than the local seabed plane, and when silt-containing tidal water passes through the outer sludge discharge channel 13, due to the increase of water depth and the reduction of flow velocity, silt can be settled and fall into the outer submerged dike and can return to the open sea along with the ebb seawater.
In a further optimized scheme, the artificial tidal-water containing bay comprises an artificial inner bay 21 and a tide inducing channel 22 which are communicated between the outer submerged dike 11 and the inner submerged dike 12, and the bottoms of the artificial inner bay 21 and the tide inducing channel 22 are provided with an inner mud discharging channel 24.
The artificial inner bay 21 is a wide water area with a certain depth formed by manually excavating the silt on the surface layer of the sea bed between the outer two submerged dikes 11 and the inner submerged dike 12, is an important component of coast leisure and landscape, and improves the substrate and the water depth condition of the original coast;
the tide inducing channel 22 is an extension part of two ends of the artificial gulf 21 to the deep water area of the open sea, is generally smaller than the width of the artificial gulf, is mainly used for water body exchange of the artificial gulf 21 and the open sea, guides the clear seawater of the open sea to the artificial gulf 21, and simultaneously carries suspended sludge in the artificial gulf 21 back to the open sea during the tide withdrawal;
the inner sludge discharge channel 24 is an inverted triangular or inverted trapezoidal groove which is located near the central axis of the artificial inner bay 21 and the moisture inducing channel 22 and is lower than surrounding bed surfaces, is formed by artificial excavation, is directly communicated to an open sea deep water area, and is used for discharging sludge water body sprayed and cleaned by the dredging component 23 into the open sea.
The area between the outer submerged dike 11 and the inner submerged dike 12 is manually excavated, silt on the surface layer is removed, and a hard soil layer below the area is excavated, so that the suspension of floating mud is reduced, an artificial inner bay 21 is formed, meanwhile, two ends of the artificial inner bay 21 extend to form a tide inducing channel 22 to the open water depth area of the open sea, and the direct exchange between the artificial inner bay 21 and the sea water of the open sea is realized. After the engineering is implemented, clear seawater in the overseas water depth area enters the artificial gulf 21 along with the tide inducing channels 22 on the two sides in the flood tide process, and is converged in the artificial gulf 21, so that the arching effect on the water body of the artificial gulf 21 is realized, and the impact of silt-containing tidal water entering from the top of the outer submerged embankment 12 can be relieved; because the water depth is increased in the artificial gulf 21, the water velocity of the artificial gulf 21 and the dynamic action of waves are effectively added, so that the cleanness of the artificial beach 15 is kept, and the argillization effect is reduced. The silt suspended by the waves in the artificial gulf 21 can be brought back directly to the open sea deep area with the ebb sea water, thereby maintaining the sea water quality in the artificial gulf 21.
In a further optimized scheme, the dredging component 23 is fixedly mounted at the bottom of the artificial inner bay 21, the dredging component 23 is a high-pressure water spraying cleaning device which is positioned at two sides of the inner sludge discharge channel 24, and the dredging component 23 is electrically connected with the electric energy storage 52 of the floating type photovoltaic power supply unit.
The dredging component 23 comprises a high-pressure pump 232 and a water spraying pipeline 231 communicated with the high-pressure pump 232, and a water spraying opening 233 is formed in the water spraying pipeline 231; high-pressure pump 232 and floating formula photovoltaic power supply unit electric connection, water jet 233 is towards interior mud discharging channel 24 for regularly spray water and clear up the silt on artifical gulf 21 well seabed surface, and collect at interior mud discharging channel 24, its theory of operation is to draw water then the pressurization blowout high-speed rivers through high-pressure pump 232, takes away the silt of deposit at artifical gulf bottom seabed surface. The dredging components 23 are symmetrically arranged at two sides of the inner sludge discharge channel, and after the dredging components start to work, the high-pressure pumps 232 at the two sides start to spray sludge and water oppositely to form underflow. Two underflow flows in opposite directions collide above the inner sludge discharge channel, and the water flow speed is reduced; meanwhile, the inner sludge discharge channel 24 is an inverted trapezoidal channel which is excavated manually, and the bottom elevation of the inner sludge discharge channel is lower than the seabed elevation of the artificial gulf 21, so that sludge carried in two water flows is deposited in the inner sludge discharge channel 24, and the purpose of cleaning the seabed is achieved.
The invention designs the inner mud discharge channel 24 in the artificial tide receiving bay, which is lower than the integral bottom elevation of the artificial tide receiving bay, so that near-bottom mud in the tide receiving bay can be more easily collected and settled, when the mud deposited in the inner mud discharge channel 24 reaches a certain degree, the dredging component 23 can be started, high-pressure water is used for exciting the settled mud, and during the period of heavy tide ebb tide, the air bag water blocking unit is opened, and the silt-containing seawater is discharged to an open sea area by riding ebb tide seawater.
In a further optimized scheme, the air bag type water blocking unit comprises water blocking air bags 31 fixedly installed at two side ports of the outer submerged dike 11 and the inner submerged dike 12, the water blocking air bags 31 are communicated with an inflator pump 32, and the water blocking air bags 31 are fixedly installed on the seabed through fixing pieces 33.
The water-blocking air bags 31 are arranged at two ends of the tide inducing channel 22 and stretch across the inner submerged dikes and the outer submerged dikes, and the water-blocking air bags 31 seal the seawater in the artificial bay 21 and the tide inducing channel 22 after being inflated to form a stable water surface, so that the situation that the landscape and the hydrophilic leisure are influenced because the inner submerged dikes 12 and the bottom bed of the artificial bay 21 are exposed after the tide is ebb is avoided; in addition, when the dredging operation is carried out in the artificial gulf 21, the water-blocking air bag 31 is deflated, so that the seawater containing the mud is discharged to the open sea through the inner mud discharging channel 24;
the inflator pump 32 is provided with two parts which are respectively arranged at two ends of the moisture inducing channel 22 and are close to the water blocking airbag 31, the water blocking airbag 31 is inflated according to functional requirements, and when the seawater in the artificial gulf 21 and the moisture inducing channel 22 needs to be sealed to form stable water surface, the inflator pump 32 inflates the water blocking airbag 31;
the fixing members 33 are a series of steel pipe piles installed on both sides of the water blocking air bag 31, and extend into the seabed to fix the water blocking air bag 31 to prevent the water blocking air bag 31 from drifting horizontally under the action of rising tide and falling tide, thereby stabilizing the water blocking air bag 31.
Because the coast of the muddy coast or the coast easy to be argillized has gentle slope and shallow water depth, the effective underwater beach part is difficult to form on the coast, the function of a sea water bathing place cannot be realized, and the hydrophilic function of the coast is poor. The invention excavates the seabed between the outer submerged dike 11 and the inner submerged dike 12, removes the silt layer on the surface layer to the hard bottom layer to form the artificial inner bay 21, which not only reduces the silt suspension, but also increases the effective water depth before the artificial beach. The invention is further provided with air bag type water-blocking units which are arranged at two ends of the artificial tide-receiving bay. When the water-blocking air bag 31 works, seawater can be blocked in the artificial tide-receiving bay, so that all seawater is prevented from flowing out along with the ebb of tide, the minimum water depth of the artificial tide-receiving bay is kept, and the hydrophilic and landscape functions of the bay are realized.
In a further optimized scheme, the floating garbage collecting unit comprises a floating collecting device 41 floating on the sea surface between the outer submerged embankment 11 and the inner submerged embankment 12, two end parts of the outer submerged embankment 11 and the inner submerged embankment 12 are respectively provided with a garbage storing device 42 for storing floating garbage captured by the floating collecting device 41, and the floating collecting device 41 and the garbage storing device 42 are respectively electrically connected with an electric energy storage 52 of the floating photovoltaic power supply unit.
Further optimization scheme, the collection unit of rubbish floats on the sea includes: the photovoltaic power supply device comprises a plurality of floating collecting devices 41, a garbage storage device 42 and cables (not shown in the figure), wherein the floating collecting devices 41 are circumferentially and fixedly installed at the top of the garbage storage device 42, and the floating collecting devices 41 and the garbage storage device 42 are electrically connected with an electric energy storage 52 of a floating photovoltaic power supply unit through the cables respectively.
