Description

Technical Field

[0001] This utility model relates to the technical field of integrated coastal protection, specifically a marine ecological revetment structure. Background Technology

[0002] Ecological seawalls refer to seawalls that replace or modify traditional seawalls through bioremediation techniques while ensuring their defensive functions. They not only possess the protective functions of traditional seawalls but also maintain biodiversity, create healthy habitats for marine life, and provide people with spaces to enjoy the sea.

[0003] Existing devices do not combine the functions of seawall revetment to improve vegetation coverage and resist erosion. As a result, existing seawall revetments are mostly inadequate in terms of ecological function. They not only provide limited space for vegetation growth, but also make it difficult for vegetation to survive or be washed away by seawater. Based on the shortcomings of existing technology, this utility model designs a marine ecological revetment structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a marine ecological revetment structure that has the advantages of improved vegetation coverage and erosion resistance compared to seawall revetment.

[0005] This utility model provides the following technical solution: a marine ecological revetment structure, including a revetment body, a shore step provided on the upper surface of the revetment body, an ecological protection mechanism provided on the revetment body to facilitate the use of ecological plants for revetment, and a fixing mechanism provided between the revetment body and the ecological protection mechanism to facilitate the fixing of the ecological protection mechanism.

[0006] An ecological protection structure, comprising vegetation bags, ecological overflow bricks, hollow retaining walls, and four-legged hollow square bricks, wherein the vegetation bags are placed on the upper surface of the bank steps, the ecological overflow bricks are placed on the upper surface of the bank steps, the hollow retaining walls are placed on the upper surface of the first bank steps, and the four-legged hollow square bricks are placed at the front edge of the main body of the bank protection structure.

[0007] As a preferred embodiment of this utility model, the fixing mechanism includes a base plate, a hinge seat, a rotating seat, a spike, a connecting arm, a hinge joint, a lower pressure plate, a through hole, and a mounting bolt. The base plate is fixedly connected to the upper surface of the bank step, the hinge seat is fixedly connected to the upper surface of the base plate, the rotating seat is rotatably connected within the hinge seat, the spike is fixedly connected to the rotating seat, the connecting arm is fixedly connected to one side of the rotating seat, the hinge joint is slidably inserted into the groove of the connecting arm, the lower pressure plate is fixedly connected to the upper surface of the hinge joint, the through hole is opened through the upper surface of the bank revetment body, and the mounting bolt is inserted through the through hole.

[0008] In a preferred embodiment of this invention, the lower surface of the planting bag is in contact with the upper surface of the lower pressure plate.

[0009] As a preferred technical solution of this utility model, the interior of the planting bag is filled with soil and plant seeds, the top and sides of the ecological overflow brick are provided with grooves, and the top groove of the ecological overflow brick is provided with soil and plants, the hollow retaining wall is hollow semi-circular and has holes on the surface, and the four-legged hollow square brick is hollow in shape.

[0010] As a preferred embodiment of this utility model, the bottom end of the mounting bolt is inserted and fixed inside the revetment body.

[0011] As a preferred technical solution of this utility model, the ecological overflow brick is provided with planting bags on both sides.

[0012] As a preferred embodiment of this invention, the spiked connector is located at the bottom of the planting bag.

[0013] As a preferred technical solution of this utility model, the slope ratio of the combined revetment body and the ecological protection mechanism is 1:2.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This marine ecological revetment structure, by setting up vegetation bags, with the interior of the vegetation bags filled with soil and suitable muddy coastal species, windproof and wave-resistant, salt-tolerant plants, can meet the protection function of the main revetment surface under the scouring action of water flow, and can also provide the necessary space for vegetation growth. The vegetation further reduces the scouring effect of water flow, thereby achieving the dual effect of taking into account both ecology and protection.

[0016] By installing ecological overflow bricks with grooves on their top and sides, and planting muddy coastal species, wind-resistant and wave-resistant, and salt-tolerant plants in the soil within these grooves, the ecological effect of the bank protection is enhanced. This results in a vegetation coverage rate of over 40% on the main body of the bank protection, while also improving the smoothness of the bank surface and providing better stability under the action of waves. This helps maintain bank stability and prevent erosion.

[0017] By setting up hollow retaining walls, which are hollow semi-circular with holes on the surface, silt can be stored in the holes as the mud and sand erode. The silt can provide a resting space for muddy coastal organisms such as shrimp and crabs, and at the same time, it can play a role in preventing and dissipating waves.

[0018] By using hollow square bricks with four legs, the high porosity and roughness of the bricks facilitate plant growth and provide attachment conditions for algae and shellfish, thus promoting the restoration of biodiversity.

[0019] 2. This marine ecological revetment structure involves placing a base plate on the shore step where vegetation bags will be placed, then inserting mounting bolts through through holes into the revetment body to fix the base plate. At this point, two spikes are pried open to the sides to maintain verticality, and the connecting arm is used to lift the lower pressure plate. The vegetation bag is then placed vertically downwards on the revetment body above the base plate. During the downward movement, the vegetation bag contacts and embeds itself in the spikes. As it continues to move downwards, the vegetation bag also contacts the lower pressure plate, pressing it down and causing the connecting arm to rotate downwards via the hinge joint. Simultaneously, the downward-moving connecting arm, through a rotating seat, drives the spikes to rotate inwards, further enhancing the fixation of the vegetation bag. The connection and fixation are achieved when the vegetation bag is completely placed on the shore step. This device facilitates improved stability after the vegetation bag is placed.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 A marine ecological revetment structure includes a revetment body 1, a shore step 101 on the upper surface of the revetment body 1, an ecological protection mechanism 2 on the revetment body 1 to facilitate the use of ecological plants for revetment, a fixing mechanism 3 between the revetment body 1 and the ecological protection mechanism 2 to facilitate the fixing of the ecological protection mechanism 2, and the slope ratio of the revetment body 1 and the ecological protection mechanism 2 after combination is 1:2.

[0028] Please see Figure 3 Ecological protection structure 2 includes a vegetation bag 201, an ecological overflow brick 202, a hollow retaining wall 203, and a four-legged hollow square brick 204. The vegetation bag 201 is placed on the upper surface of the bank step 101, the ecological overflow brick 202 is placed on the upper surface of the bank step 101, the hollow retaining wall 203 is placed on the upper surface of the first bank step 101, and the four-legged hollow square brick 204 is placed at the front edge of the bank protection body 1. The lower surface of the vegetation bag 201 is in contact with the upper surface of the lower pressure plate 307. The interior of the vegetation bag 201 is filled with soil and plant seeds. The top and sides of the ecological overflow brick 202 have grooves, and the top groove of the ecological overflow brick 202 is filled with soil and vegetation. The hollow retaining wall 203 is hollow and semi-circular with holes on the surface. The four-legged hollow square brick 204 is hollow with four legs. The ecological overflow brick 202 has vegetation bags 201 on both sides.

[0029] By setting up vegetation bags 201, which are filled with soil and suitable muddy coastal species, windproof and wave-resistant, salt-tolerant plants, the protection of the main revetment 1 under the action of water flow erosion is met, and the necessary space for vegetation growth is provided. The vegetation further reduces the erosion effect of water flow, thereby achieving the dual effect of ecological protection.

[0030] By installing ecological overflow bricks 202, with grooves on the top and sides of the bricks, and planting muddy coastal species, wind-resistant and wave-resistant, and salt-tolerant plants in the soil within these grooves, the ecological effect of the revetment is enhanced. This results in a vegetation coverage rate of over 40% for the main revetment 1, while also improving the smoothness of the revetment surface and providing better stability under the action of waves. This effectively maintains the stability of the shoreline and prevents erosion.

[0031] By setting up a hollow retaining wall 203, which is a hollow semi-circular shape with holes on the surface, silt can be stored in the holes as mud and sand erode. The silt can provide a resting space for muddy coastal organisms such as shrimp and crabs, and at the same time, it can play a role in preventing and dissipating waves.

[0032] By setting up a four-legged hollow square brick 204, and the four-legged hollow square brick 204 being in a four-legged hollow shape, high porosity and roughness are facilitated, which is conducive to plant growth, providing conditions for algae and shellfish to attach, and promoting the restoration of biodiversity.

[0033] Please see Figure 4-5 The fixing mechanism 3 includes a base plate 301, a hinge seat 302, a rotating seat 303, a spike 304, a connecting arm 305, a hinge joint 306, a lower pressure plate 307, a through hole 308, and a mounting bolt 309. The base plate 301 is fixedly connected to the upper surface of the step 101, the hinge seat 302 is fixedly connected to the upper surface of the base plate 301, the rotating seat 303 is rotatably connected inside the hinge seat 302, and the spike 304 is fixedly connected to the rotating seat 303. The connecting arm 305 is fixedly connected to one side of the rotating seat 303, the hinge joint 306 is slidably inserted into the groove of the connecting arm 305, the lower pressure plate 307 is fixedly connected to the upper surface of the hinge joint 306, the through hole 308 is opened through the upper surface of the revetment body 1, the mounting bolt 309 is inserted through the through hole 308, the bottom end of the mounting bolt 309 is inserted and fixed in the revetment body 1, and the spike 304 is movably inserted into the bottom of the planting bag 201.

[0034] By providing spikes 304, connecting arms 305, hinge joints 306, and lower pressure plates 307, the stability of the planting bags 201 on the bank steps 101 is improved by inserting them into the planting bags 201 and fastening them inward. By providing through holes 308 and mounting bolts 309, the bottom plate 301 is connected to the bank protection body 1, preventing the bottom plate 301 from detaching from the bank protection body 1.

[0035] Working principle: When a marine ecological revetment structure is used, in the initial state, the shore step 101 is first set on the upper surface of the revetment body 1. The vegetation bags 201 and ecological overflow bricks 202 are placed alternately on the shore step 101. Hollow retaining walls 203 and four-legged hollow square bricks 204 are respectively set on the first step of the shore step 101 and the front end of the revetment body 1 to improve the vegetation coverage and enhance the ecological level of the shoreline. The fixing mechanism 3 set between the shore step 101 and the vegetation bags 201 can effectively fix the vegetation bags 201 to prevent the vegetation bags 201 from being washed away by large waves.

[0036] When it is necessary to improve the stability of the planted bag 201 after placement, first place the base plate 301 on the bank step 101 where the planted bag 201 is to be placed. Then, insert the mounting bolt 309 through the through hole 308 into the bank revetment body 1 to fix the base plate 301. At this time, pry the two spikes 304 apart to keep them vertical and use the connecting arm 305 to lift the lower pressure plate 307. Then, place the planted bag 201 vertically downward on the bank revetment body 1 above the base plate 301. During the downward placement process, the planted bag 201 will... The spikes 304 contact and penetrate the interior of the plant bag 201. During the continuous downward movement, the plant bag 201 will also contact the lower pressure plate 307 and press down the lower pressure plate 307 so that it pushes the connecting arm 305 to rotate and move downward through the hinge joint 306. At the same time, the downward moving connecting arm 305 drives the spikes 304 to rotate and buckle inward through the rotating seat 303 to further improve the fixation of the plant bag 201 until the plant bag 201 is completely placed on the bank step 101 to achieve connection and fixation. This device facilitates the improvement of the stability of the plant bag 201 after placement.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
