Description

Technical Field

[0001] The invention belongs to the technical field of marine engineering and water environment engineering, and specifically relates to an ecological restoration device for an ocean beach and a method for using the device. Background Art

[0002] In recent years, due to the discharge of land-based pollutants and the generation of large amounts of suspended sediment by nearshore projects, natural wetlands have been reduced, and the "vegetation" of some coastal mudflats has been rapidly disappearing, or due to the continuous accumulation of sand from the estuary, some mudflats are turning into a "desert". For example, the coastal zones around Hainan Island and Beihai, Guangxi, have rapidly disappeared seagrass beds that are in urgent need of restoration. Similarly, in the Yangtze River estuary, Hengsha Island alone has hundreds of square kilometers of bare beaches without any vegetation, and the seabed is turning into a "desert". Bare beaches have caused many fish to lose their habitats, reducing biodiversity, density, and serious decline in biological resources, showing a trend of ecological desertification.

[0003] The bare beach has become a typical "desert" on the seabed because there are no plants on the beach surface. Many fish and aquatic organisms have lost their habitats, and the biodiversity is seriously insufficient. The most effective way to restore this kind of bare beach is to plant seaweed artificially, but aquatic plants cannot be planted on the bare beach, and the sown grass seeds will be quickly washed away by the tide. Secondly, grass seeds and grass seedlings are difficult to grow directly on the sand.

[0004] Seagrass is a natural ecological barrier in the coastal zone. Seagrass beds growing in patches can reduce wave energy and current energy, maintain the stability of the seabed, and play an important role in consolidating the seabed matrix and maintaining the coastline. The purpose of artificially planting seagrass on the beach is to improve the ecological environment of the sea area, create a good environment for marine life to live, and provide a place for fish to reproduce, grow, feed and shelter, so as to achieve the purpose of protection, proliferation and increase of fish catch.

[0005] Current situation: Artificial planting of seaweed on the beach is difficult, labor-intensive, inefficient, and has a low survival rate. Even if it is planted on the seabed, it is often washed away by the seabed currents before it takes root. For example, in the open waters of Gaolong Bay on the east coast of Hainan Island, a "seabed soil grid" is made, that is, iron sheets are used to fix the size of the planting grids, and at the same time, the fishing nets are pressed down so that they can catch the loose bottom sediment, thereby slowing down the water flow in the microenvironment, settling suspended matter, and capturing nutrients, thereby stabilizing the bottom sediment and fixing the seaweed plants. However, this method is inconvenient to operate underwater, and the grid is difficult to completely fix the planting soil and seaweed, resulting in a low survival rate of seaweed.

[0006] The Chinese invention patent CN116508702A under the prior art provides a beach seaweed planter and fish reef device and its installation method. The planter takes a section of bamboo tube and uses it vertically for planting. The planting area and utilization rate are obviously low, and it is difficult to place it in the water.

[0007] The existing methods have defects such as high labor consumption, high material consumption, lack of environmental protection, and unstable component fixation. In short, the cost is high, implementation is difficult, and the expected effect cannot be achieved. Therefore, it is necessary to study and improve the existing seaweed planting technology.

[0008] In summary, the ocean beach is in urgent need of aquatic ecological restoration technology or equipment to control the desertification of marine waters and provide habitats for various bait organisms at the bottom of the food chain. How to artificially plant seaweed to improve the ecological environment of the beach, it is urgent to innovate the planting model of aquatic plants on the beach to change the harsh environment of the ocean beach, and innovative ecological restoration methods are needed.

[0023] Therefore, the ecological restoration device for the ocean beach of the present invention has the following beneficial effects:

[0024] (1) A new resource-saving, low-carbon and environmentally friendly seaweed planting technology was proposed to solve the problem of planting aquatic plants on bare beaches.

[0025] (2) The components of the present invention are standardized, and the same components are easy to use, standardized, and factory-made; the structure is simple, safe and reliable. The materials are easy to develop and produce, and can be placed on the beach surface, and the planting soil can be kept from being lost.

[0026] (3) Bare beaches cannot grow plants. The restoration device is not only a carrier for aquatic plants, but also protects their growth. After falling onto the beach, they slowly take root in the sand. The planting tube is friendly and provides a habitat for plankton, thus providing a food chain for fish.

[0027] (4) The main body of the repair device is made of bamboo tubes. Bamboo resources are abundant, the material is natural, and has good biological affinity, which is particularly suitable for aquatic life. The main body of the repair device is a bamboo planting tube, which can only be decomposed after more than ten years in the sea. It is natural and pollution-free. When it rots and decomposes, it can also form lignin, which will not damage the environment and can continue to provide nutrition for aquatic plants and aquatic animals. When the planting tube material rots and decomposes, the aquatic plants have already grown into patches, and the beach has been completely cured.

[0028] (5) Since the center of gravity of the repair device is always below the center of buoyancy, it can be ensured that it falls horizontally to the beach surface, thereby achieving the purpose of planting seaweed on the bare beach. The user lowers the repair device horizontally according to the arrangement position on the boat. Since the overall specific gravity of the repair device is greater than the specific gravity of water, and the center of buoyancy is always above the center of gravity, it can sink in the water in a horizontal posture. The center of gravity of the repair device is below the point of buoyancy, similar to a "tumbler". Under the self-control of its own structure, during the sinking process, although it shakes, it will fall to the surface of the bare beach in a horizontal posture, and through its own weight and the continuous shaking of the device by the ocean current, the landing piles are continuously inserted into the sand until the bamboo tube completely falls to the ground.

[0029] (6) The present invention uses the principle of sand vibrating into piles. After the piles are driven into the sand, the waves reciprocate to impact the repair device, and the piles swing left and right and continue to drive into the sand until the planting tube is completely consistent with the beach surface. No manual control is required, and no power is required. The planter can land smoothly, ensuring the landing and growth of seaweed. The seaweed planting structure that can create a micro-silt environment is used to form a biological matrix, providing living and foraging space for benthic organisms, enhancing ecological functions, and producing good ecological effects.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments and drawings specifically illustrate the ecological restoration device for the ocean beach of the present invention and its use method.

[0041] <Example 1>

[0042] Figure 1 is a top view of an ecological restoration device for an ocean beach according to Embodiment 1 of the present invention; Figure 2 It is a longitudinal cross-sectional view of the ecological restoration device for the ocean beach according to Example 1 of the present invention.

[0043] in, Figure 2 The accompanying figure (a) is a side cross-sectional view of the ecological restoration device for the ocean beach without planting soil and aquatic plants; the accompanying figure (b) is a side cross-sectional view of the ecological restoration device for the ocean beach when it is projected onto the ocean beach.

[0044] like Figure 1 and Figure 2 As shown, this embodiment provides an ecological restoration device 100 for an ocean beach, including a planting unit 10 , a fixing unit 20 and a buoyancy unit 30 .

[0045] Figure 3 It is a radial cross-sectional schematic diagram of the ecological restoration device for ocean beach in Example 1 of the present invention when it does not include a fixed unit and a buoyancy unit.

[0046] like Figure 1 to Figure 3 As shown, the planting unit 10 includes a planting tube 11 , planting soil 12 , a cushion material 13 and a plug 14 .

[0047] The planting tube 11 is a long cylindrical structure that is horizontally arranged and closed at both ends. It is made of a thicker section of about 2m in length in the middle and lower part of a mature bamboo, and all the bamboo nodes in the bamboo tube are removed.

[0048] Figure 4 It is a schematic diagram of a radial cross section of the planting tube of Example 1 of the present invention.

[0049] like Figures 1 to 4 As shown, the planting tube 11 has several pairs of slots distributed along the length direction, each pair of slots includes an upper slot 11a located at the upper side and a lower slot 11b located at the lower side. The spacing between each pair of slots distributed along the length direction of the planting tube 11 is 20 cm.

[0050] The upper notch 11a and the lower notch 11b of the same pair of notches are located at the two ends of the same radial direction of the planting tube 11. The upper notch 11a and the lower notch 11b are square, 12 to 15 cm wide and 15 to 20 cm long.

[0051] The planting tube 11 has a plurality of insertion holes 11c at both ends in the length direction along the radial direction.

[0052] The planting soil 12 is disposed inside the planting tube 11 for the growth of aquatic plants 40. Specifically, in this embodiment, the planting soil 12 is a 1:1 mixture of plant debris and soil, and the height of the planting soil 12 in the planting tube 11 does not exceed 2 / 3 of the radial inner diameter of the planting tube 11.

[0053] The aquatic plant 40 grows in the planting soil 12, the branches and leaves 40a of the aquatic plant 40 grow out from the upper notch 11a, and the root system 40b of the aquatic plant 40 passes through the lower notch 11b and takes root in the sand layer of the beach.

[0054] like Figure 3 As shown, the mat material 13 is a straw mat woven from plant fibers, and its mesh inner diameter is 10 to 15 mm. The mat material 13 matches the inner surface of the planting tube 11 to form an arc shape and covers the area where the lower groove 11b is located, so as to prevent the planting soil 12 from leaking from the lower groove 11b and allow the roots 40b of the aquatic plants 40 to pass through.

[0055] like Figure 1 and Figure 2 As shown, the plug 14 includes a bamboo piece 141 and a bamboo raft wall 142 .

[0056] At one end of the planting tube 11 , at least two bamboo pieces 141 are inserted through the insertion hole 11 c along the radial direction of the planting tube 11 .

[0057] The bamboo raft wall 142 is arranged at both ends of the inner part of the planting tube 11 and abuts against the bamboo piece 141 to prevent the planting soil 12 from leaking from both ends of the planting tube 11. Specifically, in this embodiment, each bamboo piece 141 is fixed to the bamboo raft wall 142 by at least two places tied with ropes.

[0058] Figure 5 It is a radial cross-sectional schematic diagram of the ecological restoration device for the ocean beach in Example 1 of the present invention without planting soil and cushion material.

[0059] like Figure 1 to Figure 5 As shown, the fixing unit 20 includes a slot 21 and a ground stake 22 .

[0060] The card slot 21 is a U-shaped structure made of strip plastic steel, which is carded to the radial periphery of the planting tube 11 without blocking the upper notch 11a and the lower notch 11b of the planting tube 11. There are 3 card slots 21 and they are evenly distributed along the length direction of the planting tube 11.

[0061] Specifically, in this embodiment, the three slots 21 cooperate with each other to fix a group (2) of planting tubes 11 in parallel, and a fixing nail 1 is also penetrated between the contacting walls of the slots 21 and the planting tubes 11 so that radial relative rotation will not occur between the slots 21 and the planting tubes 11.

[0062] The ground pile 22 is correspondingly arranged at the bottom of the slot 21, and is used to be inserted and fixed in the sand layer of the beach. Specifically, the ground pile 22 in this embodiment is made of square plastic, and the pile length is not more than 15 cm.

[0063] The buoyancy unit 30 includes a buoyancy block 31 and a counterweight block (not shown).

[0064] The size of the buoyancy block 31 matches the slot 21, and it is detachably installed on the upper part of the slot 21 so that the center of gravity of the ecological restoration device 100 for the ocean beach is located below its buoyancy center. The buoyancy block 31 is used to provide buoyancy for the slot 21 and the planting tube 11 embedded therein so that the upper slot 11a faces upward and the lower slot 11b faces downward, ensuring that the ecological restoration device 100 for the ocean beach is in a horizontal state as a whole on the beach.

[0065] Specifically, the buoyancy block 31 in this embodiment is a rectangular EPS foam board, and its thickness is determined according to the required buoyancy. The required buoyancy is generally determined by the overall specific gravity of the device being twice the specific gravity of water.

[0066] A support plate 31 a is provided at the bottom of the buoyancy block 31 . One side of the support plate 31 a is hinged to the slot 21 , and the other side of the support plate 31 a is locked to the slot 21 .

[0067] The counterweight block (not shown) is arranged at the bottom of the slot 21 to increase the gravity of the ecological restoration device 100 for the ocean beach and prevent the buoyancy of the buoyancy block 31 from being too large and thus affecting the sinking of the ecological restoration device 100 for the ocean beach.

[0068] This embodiment also provides a method for using an ecological restoration device for an ocean beach, comprising the following steps:

[0069] S10, the planting tubes 11 made of bamboo material are clamped into three slots 21 in a group (2 tubes) side by side, and then at each slot 21, at least two fixing nails are used to penetrate the slot 21 and the wall of the planting tube 11 for fixing.

[0070] S20, locking the buoyancy block 31 on the clamping groove 21 through the support plate 31a, so that the buoyancy block 31 and the clamping groove 21 cooperate with each other to be fixed in the radial direction of the planting tube 11.

[0071] S30, pouring planting soil 12 and seeds of aquatic plants 40 into the planting tube 11 through the upper groove 11a, wherein suitable aquatic plants should be selected according to different sea areas, for example, sea calamus or sea scutellaria should be selected for Guangtan, Hengsha Island, Shanghai.

[0072] S40, the user puts down the ecological restoration device 100 for the light beach of the ocean assembled in step S10 to step S30 horizontally on the boat according to the arrangement position, because the overall specific gravity of the device is greater than the specific gravity of water, and the buoyancy center is always above the gravity center, so that it can sink in the water in a horizontal posture. The center of gravity of the ecological restoration device 100 for the light beach of the ocean is below the point of buoyancy, similar to a "tumbler". Under the self-control of its own structure, during the sinking process, although it shakes, it will fall to the surface of the light beach in a horizontal posture, and through its own weight and the continuous shaking of the device by the ocean current, the landing pile 22 is continuously inserted into the sand until the planting tube 11 is completely on the ground.

[0073] After the ground pile 22 is driven into the sand, the waves reciprocate and impact the device, and the ground pile 22 swings left and right and continuously drives into the sand until the planting tube 11 completely matches the beach surface. The seaweed planting structure that can create a micro-silt environment is used to form a biological matrix, providing a living and foraging space for benthic organisms, enhancing the ecological function and producing a good ecological effect.

[0074] The root system 40b of the plant penetrates the sparse large mesh mat material 13 at the bottom of the planting device and slowly penetrates into the sand layer of the beach. As the plant grows, the growing plant root system 40b organically combines the ecological restoration device 100 of the ocean beach with the beach and continuously expands outward, forming new plants growing outside the ecological restoration device 100 of the ocean beach, from point to surface. After the beach vegetation spreads, it provides a suitable benthic habitat and food source for benthic organisms.

[0075] <Example 2>

[0076] Figure 6 It is a schematic diagram of the radial cross-section of a single planting tube of the ecological restoration device for the ocean beach according to Example 2 of the present invention.

[0077] like Figure 6 As shown, this embodiment provides an ecological restoration device 101 for an ocean beach, comprising a planting unit 10 , a fixing unit 20 ′ and a buoyancy unit 30 .

[0078] Planting Unit 10 The planting unit 10 includes a planting tube 11 , planting soil 12 , a cushion material 13 and a plug 14 .

[0079] The fixing unit 20 ′ includes a slot 21 ′ and a ground stake 22 .

[0080] The arrangement of the planting unit 10, the ground piles 22 and the buoyancy unit 30 is substantially similar to that of the first embodiment and will not be repeated.

[0081] The only difference between this embodiment and the first embodiment is that the number of the clamping grooves 21 ′ is 3 and only one planting tube 11 is clamped along the length direction of the planting tube 11 .

[0082] The method of using the ecological restoration device for the ocean beach in this embodiment is generally similar to that in Example 1 and will not be repeated.

[0083] Functions and Effects of the Embodiments

[0084] An ecological restoration device for an ocean beach provided according to the present embodiment comprises: a planting tube, which is a long cylindrical structure arranged horizontally and closed at both ends, and the planting tube is provided with a plurality of pairs of slots along the length direction, and each pair of slots comprises an upper slot located on the upper side and a lower slot located on the lower side; planting soil, which is arranged inside the planting tube and is used for the growth of aquatic plants; a cushion material, which is laid on the inner bottom of the planting tube and covers the lower slot, and is used for preventing the planting soil from leaking from the lower slot and for the roots of aquatic plants to pass through; a slot, which is a U-shaped structure, which is clamped on the radial periphery of the planting tube, and the number of the slots is at least 3 and is evenly distributed along the length direction of the planting tube; a ground pile, which is arranged at the bottom of the slot and is used for being inserted and fixed in the sand layer of the beach; and a buoyancy block, which is detachably mounted on the upper part of the slot so that the center of gravity of the ecological restoration device for an ocean beach is located below its buoyancy center.

[0085] Therefore, the ecological restoration device for the ocean beach of this embodiment has the following beneficial effects:

[0086] (1) A new resource-saving, low-carbon and environmentally friendly seaweed planting technology was proposed to solve the problem of planting aquatic plants on bare beaches.

[0087] (2) The components of this embodiment are standard, and the same components are easy to use, easy to standardize and factory-produce; the structure is simple, safe and reliable. The materials are easy to develop and produce, and can be placed on the beach surface, and the planting soil can be kept from being lost.

[0088] (3) Bare beaches cannot support plant growth. The restoration device is both a carrier of aquatic plants and a protective device for their growth. After falling onto the beach, the plants slowly take root in the sand. The bamboo tubes are friendly and provide a habitat for plankton, thus providing a food chain for fish.

[0089] (4) The main body of the repair device is made of bamboo tubes. Bamboo resources are abundant, the material is natural, and has good biological affinity, which is particularly suitable for aquatic life. The main body of the repair device is made of bamboo tubes, which can only be decomposed after more than ten years in the sea. It is natural and pollution-free. When it rots and decomposes, it can also form lignin, which will not damage the environment and can continue to provide nutrition for aquatic plants and aquatic animals. When the planting tube material rots and decomposes, the aquatic plants have already grown into patches, and the beach has been completely cured.

[0090] (5) Since the center of gravity of the repair device is always below the center of buoyancy, it can be ensured that it falls horizontally to the beach surface, thereby achieving the purpose of planting seaweed on the bare beach. The user lowers the repair device horizontally according to the arrangement position on the boat. Since the overall specific gravity of the repair device is greater than the specific gravity of water, and the center of buoyancy is always above the center of gravity, it can sink in the water in a horizontal posture. The center of gravity of the repair device is below the point of buoyancy, similar to a "tumbler". Under the self-control of its own structure, during the sinking process, although it shakes, it will fall to the surface of the bare beach in a horizontal posture, and through its own weight and the continuous shaking of the device by the ocean current, the landing piles are continuously inserted into the sand until the bamboo tube completely falls to the ground.

[0091] (6) This embodiment uses the principle of sand vibrating into piles. After the piles are driven into the sand, the waves reciprocate to impact the repair device, and the piles swing left and right and continue to drive into the sand until the planting tube is completely consistent with the beach surface. No manual control is required, and no power is required. The planter can land smoothly, ensuring the landing and growth of seaweed. The seaweed planting structure that can create a micro-silt environment is used to form a biological matrix, providing living and foraging space for benthic organisms, enhancing ecological functions, and producing good ecological effects.

[0092] Further, the planting tube is made of the thicker section of the middle and lower part of the mature bamboo, and the bamboo joints in the bamboo tube are all removed. The bamboo tube is used to facilitate the planting of seaweed and provide a seaweed growth base bed. The two functions are combined into one. Bamboo is used as a planting carrier. Bamboo resources are rich, ecological and friendly. The bamboo cavity is large and suitable for filling with planting soil. Seaweed seedlings grow in the bamboo tube and are protected to survive. The bamboo tube is an ideal base bed shelter for seaweed. When the seaweed roots are strong and the leaves are lush, they slowly grow out of the notches on the bamboo tube body, and the root system passes through the lower notch and takes root in the sand, thereby completing the seaweed planting. If the planting soil is piled on the beach, the waves are constantly washed away and the seaweed cannot take root. Planting soil is set in the cavity of the bamboo, and the shell of the bamboo tube protects the seaweed to grow in the cavity. The seaweed branches and leaves extend from the notches set on the bamboo tube, and the root system continuously extends to the beach sand, splits and sprouts, and continuously grows around the bamboo tube. It can improve the microcirculation around the roots of aquatic plants and create a relatively suitable growth environment for them.

[0093] Furthermore, the two ends of the planting tube in the length direction have a plurality of insertion holes in the radial direction, and plugs are also arranged at the two ends of the planting tube in the length direction, and the plugs include bamboo pieces and bamboo raft walls. At one end of the planting tube, at least two bamboo pieces are arranged through the insertion holes in the radial direction of the planting tube, and the bamboo raft walls are arranged at the two ends of the planting tube and abut against the bamboo pieces. Such an arrangement can prevent the planting soil in the planting tube from leaking out from the two ends.

[0094] Furthermore, the planting soil is a mixture of plant debris and soil in a ratio of 1:1, and the height of the planting soil in the planting tube does not exceed 2 / 3 of the radial inner diameter of the planting tube. The planting soil can increase nutrition and is conducive to the extension of plant roots.

[0095] Further, each bamboo sheet is fixed to the bamboo raft wall by rope binding at least at two places. Such arrangement enables the plug to be more securely arranged at both ends of the planting tube.

[0096] Furthermore, the mat material is a straw mat made of plant fibers, the inner diameter of the mesh is 10-15 mm, and the mat material matches the inner surface of the planting tube to form an arc shape and covers the area where the lower notch is located. This arrangement can prevent the planting soil from leaking from the lower notch and allow the roots of aquatic plants to pass through.

[0097] Furthermore, the clamping groove does not block the notch, and a fixing nail is also provided between the wall surfaces of the clamping groove and the planting tube that contact each other. In this way, radial relative rotation does not occur between the clamping groove and the planting tube.

[0098] Furthermore, the size of the buoyancy block matches the card slot, and the bottom of the buoyancy block has a support plate, one side of the support plate is hinged to the card slot, and the other side is locked with the card slot. The buoyancy block is made of EPS foam board, which is a lightweight material with low water absorption, corrosion resistance, antifreeze, oxidation resistance, and UV resistance. It is not eroded by seawater, chemicals, oil stains, and aquatic organisms, and is pollution-free and environmentally friendly. It is light in weight and has high mechanical strength. The service life is at least 10 years, and except for strong natural forces and improper human use, it almost does not require any maintenance and repair costs. It is easy, fast, and flexible to assemble, and the overall modular structure can meet the needs of various conditions and is cheap.

[0099] Furthermore, the ecological restoration device for the light ocean beach also includes a counterweight block, which is arranged at the bottom of the slot. Such an arrangement can increase the gravity of the ecological restoration device for the light ocean beach, and avoid the buoyancy of the buoyancy block being too large to affect the sinking of the ecological restoration device for the light ocean beach.
