Description

Technical Field

[0001] The invention relates to the technical field of mangrove wetland protection, and in particular to a method for quickly restoring an ecological structure of a degraded mangrove. Background Art

[0002] Mangroves are one of the most valuable forms of coastal wetlands. They are a buffer and transition zone between land and sea, and an ideal home for countless benthic and marine organisms. The organic matter produced by mangroves will be fed back to the mudflats and the ocean in the form of litter, providing a large source of food for the organisms living here, and playing a great role in protecting and promoting biodiversity. In recent years, with the increase in population in coastal areas, rapid economic development and rapid urbanization, coastal engineering construction, overdevelopment, and the total amount of industrial sewage, urban domestic sewage, and agricultural production sewage discharged has continued to increase. The coastal mangrove wetlands have been severely damaged, the area has been sharply reduced, the water and soil have been seriously eutrophicated, and the integrity of biodiversity and ecological structure has been reduced. There are also many coastal industries and coastal new areas, which bring a large amount of sewage and industrial residue discharge, which eventually caused the collapse of the entire mangrove wetland ecological structure.

[0003] In the prior art, a Chinese patent with application number CN202120892600.9 discloses a method for rapidly restoring the ecological structure of degraded mangroves, which absorbs, transforms and degrades organic pollutants by injecting microbial preparations into deep water and soil, thereby repairing the ecological structure of mangroves. Although it can repair and manage the ecological structure of mangrove wetlands to a certain extent by laying a delivery pipeline under the tree planting area, it is costly to lay a delivery pipeline in the soil, and it is not easy to repair and treat the delivery pipeline when it is damaged; and because the root system of mangrove plants is not in a plane, but grows vertically from top to bottom, it is impossible to repair and manage the silt layers of different depths and fully provide nutrients for the plant roots. It can only repair and manage the silt at a single height, and the nutrients provided to the plant roots are not comprehensive, resulting in poor ecological restoration effects of mangrove wetlands. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a method for quickly restoring the ecological structure of degraded mangroves.

[0011] Preferably, a connecting tube is provided between the metal tube and the inner material tube, a plurality of evenly distributed first through holes are provided on the outer side of the inner material tube, and a plurality of second through holes matching with the first through holes are provided on the protective tube.

[0012] Preferably, the driving assembly includes a fixed seat fixed on the metal tube, the fixed seat is rotatably connected to a rotating shaft inside the metal tube, a torsion spring is arranged between the rotating shaft and the fixed seat, a paddle is arranged on the shaft body of the rotating shaft placed in the metal tube, and the end of the rotating shaft away from the fixed seat passes through the metal tube and is fixedly connected to the protective tube.

[0013] Preferably, a guide block for guiding the liquid is fixedly provided in the metal tube, and a movable groove for the movement of the connecting tube is provided on the top of the protection tube.

[0014] Preferably, a sleeve for covering the second through hole is provided on the outer side of the protective tube, a counterweight block is rotatably provided on the bottom of the sleeve, a movable tube is fixedly provided on the top of the sleeve, a telescopic rod is provided between the movable tube and the metal tube, and a movable groove matching with the metal tube is opened on the movable tube.

[0015] Preferably, an air guide plate is provided on the top of the movable tube, and the bottom of the inner material tube is rotatably connected to the positioning rod.

[0016] Preferably, a bending and moving rod is fixedly provided at the bottom of the inner material tube, and the bending and moving rod moves in the silt layer at the bottom of the water area to be repaired.

[0017] Preferably, the bending and moving rod comprises an L-shaped connecting rod fixedly connected to the positioning rod, a plurality of movable tubes are sleeved on the L-shaped connecting rod, a coil spring is arranged between each movable tube and the L-shaped connecting rod, and a moving rod 122 is fixedly provided on the movable tube.

[0018] Preferably, a water pump is further included, wherein the water outlet of the water pump is connected to the water inlet of the first material guide pipe, and the water inlet of the water pump is connected to a soil remediation agent box.

[0019] Preferably, it also includes a fencing structure, which is arranged at the edge of the water area to be restored. The fencing structure includes artificial fencing and / or ecological fencing. The artificial fencing includes sandbags or mud bags, and the ecological fencing is made of piles of wood or oyster shells.

[0020] Compared with the prior art, the present invention provides a method for rapidly restoring the ecological structure of degraded mangroves, which has the following beneficial effects:

[0021] 1. The degraded mangroves can quickly restore their ecological structure. The inner material pipe is inserted into the silt layer in the water area to be restored through positioning rods. The soil remediation agent is transported to the silt layer more comprehensively through multiple inner material pipes connected by guide pipes. The soil remediation agent provides the elements required for the growth of mangrove plants, and the soil remediation agent effectively repairs and manages the silt in the water area, absorbs, transforms and degrades organic pollutants, and has good economic, social and ecological benefits. At the same time, the inner material pipe uses vertical plug-in instead of burying in the water and soil, which is convenient for timely treatment of the inner material pipe when it is damaged.

[0022] 2. The degraded mangrove quickly restores its ecological structure by arranging a protective pipe on the outside of the inner material pipe. When the inner material pipe is not being repaired, the protective pipe blocks the first through hole of the inner material pipe to prevent silt and impurities in the water from entering the inner material pipe, causing the inner material pipe to be blocked and affecting the subsequent repair and use of the inner material pipe. When the inner material pipe is being repaired, the soil remediation agent in the guide pipe impacts the toggle plate under the guidance of the guide block, so that the toggle plate drives the protective pipe to rotate through the rotating shaft. After the protective pipe rotates, the second through hole is aligned with the first through hole, so that the soil remediation agent that enters the inner material pipe from the guide pipe through the connecting pipe can flow out from the through hole. When the outflowing soil remediation agent repairs the wetland silt, it can simultaneously limit external substances from entering the inner material pipe through the through hole to ensure the continuous repair and use of the inner material pipe.

[0023] 3. The ecological structure of the degraded mangroves is quickly restored by arranging a casing on the outside of the protective pipe. The bottom of the casing is placed on the upper side of the silt through a counterweight block, so that the casing blocks the part of the protective pipe body on the upper side of the silt, thereby avoiding the overlap of the through holes of the protective pipe and the inner material pipe during the repair work, so that the soil repair agent also flows out of the through holes of the protective pipe placed on the silt layer, resulting in a large amount of soil repair agent sprayed on the surface of the silt layer, causing a waste of the soil repair agent. In addition, the casing can automatically adjust its height according to the insertion depth of the positioning rod under the action of the counterweight block, and has strong applicability.

[0024] 4. The degraded mangrove quickly restores its ecological structure by setting an air guide plate on the top of the mobile tube. When the air guide plate is blown by wind, it drives the mobile tube to rotate. The mobile tube drives the material guide tube to rotate through the telescopic rod. The material guide tube drives the protective tube and the inner material tube connected to it to rotate through the connecting tube, thereby automatically adjusting the outflow range of the soil remediation agent of the inner material tube, making the soil remediation range of the inner material tube more comprehensive, and effectively improving the restoration effect of the mangrove wetland.

[0025] 5. The degraded mangroves can quickly restore their ecological structure. By setting up artificial fences or ecological fences around the waters to be restored, they can serve as barriers to intercept garbage and further restore the ecological structure of the mangroves.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Example 1: Reference Figure 1-10 , a method for rapidly restoring an ecological structure of a degraded mangrove forest, comprising a plurality of inner material pipes 2 arranged in a water area 1 to be restored, and further comprising:

[0041] The material guide pipe 3 includes a metal pipe 301 connected to the inner material pipe 2 and a connecting hose 302 connected to both ends of the metal pipe 301. Two adjacent inner material pipes 2 are connected through the material guide pipe 3.

[0042] A positioning rod 4, which is disposed at the bottom of the inner material pipe 2 and is used to fix the inner material pipe 2 in the silt layer 101 in the water area 1 to be repaired; and

[0043] A protection pipe 5, which is sleeved on the outside of the inner material pipe 2 and is used to prevent impurities in the water area 1 to be repaired from entering the inner material pipe 2;

[0044] A driving component for driving the protective tube 5 to move is arranged in the material guiding tube 3 .

[0045] Furthermore, it also includes a water pump 13, the water outlet of the water pump 13 is connected to the water inlet of the first material guide pipe 3, and the water inlet of the water pump 13 is connected to the soil remediation agent box 131.

[0046] Furthermore, a connecting pipe 3011 is provided between the metal pipe 301 and the inner material pipe 2 , a plurality of evenly distributed first through holes 201 are provided on the outer side of the inner material pipe 2 , and a plurality of second through holes 501 matching with the first through holes 201 are provided on the protective pipe 5 .

[0047] Furthermore, the driving assembly includes a fixed seat 6 fixed on the metal tube 301, the fixed seat 6 is rotatably connected to a rotating shaft 601 inside the metal tube 301, a torsion spring 602 is arranged between the rotating shaft 601 and the fixed seat 6, and a paddle plate 603 is arranged on the shaft body of the rotating shaft 601 placed inside the metal tube 301, and the end of the rotating shaft 601 away from the fixed seat 6 passes through the metal tube 301 and is fixedly connected to the protective tube 5.

[0048] Furthermore, a guide block 3012 for guiding the liquid is fixedly disposed in the metal tube 301 , and a movable groove 502 for the movement of the connecting tube 3011 is provided on the top of the protection tube 5 .

[0049] Specifically, the staff evenly inserts a plurality of positioning rods 4 into the silt layer 101 in the water area 1 to be repaired, especially into the soil near the mangrove plants, so that a plurality of inner material tubes 2 are evenly distributed in the water area 1 to be repaired, and two adjacent inner material tubes 2 are connected by the guide tube 3. The protective tube 5 can shield the first through hole 201 of the inner material tube 2 when no repair work is being performed, so as to prevent silt and impurities in the water body from entering the inner material tube 2, causing the inner material tube 2 to be blocked, and affecting the subsequent repair and use of the inner material tube 2;

[0050] When performing the repair work, the water pump 13 is controlled to run, the water pump 13 extracts the soil repair agent in the soil repair agent box 131, and transports it to the metal pipe 301 through the guide pipe 3. The soil repair agent drives the toggle plate 603 through the guiding effect of the guide block 3012, and the toggle plate 603 drives the protection tube 5 to rotate through the rotating shaft 601, so that the protection tube 5 rotates relative to the inner material tube 2, and the second through hole 501 of the protection tube 5 is aligned with the first through hole 201 of the inner material tube 2. The soil repair agent in the metal pipe 301 is connected to the inner material tube 2. 3011 enters the inner material tube 2 and flows out through the through hole. When the outflowing soil repair agent impacts outward to repair the wetland water body and silt, it can also limit external substances from entering the inner material tube 2 through the through hole, ensuring the continuous repair and use of the inner material tube 2. The soil repair agent repairs the soil while providing the mangrove plants with the elements required for growth; the protection tube 5 and the through hole setting of the inner material tube 2 effectively avoid the need to set a valve or other plugging parts at each through hole of the inner material tube 2 to intercept liquid or isolate silt, thereby reducing the difficulty and cost of installation;

[0051] The present invention facilitates the uniform transportation of soil remediation agents into the silt layer 101 through a plurality of inner material pipes 2, so that the soil remediation agents can effectively repair and treat silt at different heights in the water area, absorb, transform and degrade organic pollutants, and have good economic, social and ecological benefits; at the same time, the inner material pipes 2 use a vertical plug-in method instead of being buried in the water and soil, which is convenient for timely treatment of the inner material pipes 2 when they are damaged.

[0052] Example 2: Reference Figure 3 , Figure 7 , Figure 8 and Fig. 9 , a rapid restoration ecological structure for degraded mangroves. On the basis of Example 1, further, a sleeve 7 for covering the second through hole 501 is provided on the outer side of the protective tube 5, a counterweight block 701 is rotatably provided at the bottom of the sleeve 7, a moving tube 8 is fixedly provided on the top of the sleeve 7, a telescopic rod 801 is provided between the moving tube 8 and the metal tube 301, and a moving groove 802 matching the metal tube 301 is opened on the moving tube 8.

[0053] Specifically, a sleeve 7 is sleeved on the outside of the protective tube 5, and the bottom of the sleeve 7 is placed on the surface of the silt layer 101 through a counterweight block 701. The counterweight block 701 has a certain weight to prevent the tube body from being displaced under the impact of the water body. The sleeve 7 blocks the tube body portion of the protective tube 5 placed on the surface of the silt layer 101 to prevent the protective tube 5 from overlapping with the through hole of the inner material tube 2 during the repair work, causing the soil remediation agent to flow out of the through hole of the protective tube 5 placed above the water, resulting in a large amount of soil remediation agent being sprayed on the surface of the silt layer 101, causing a waste of the soil remediation agent. In addition, the sleeve 7 can automatically adjust its height according to the insertion depth of the positioning rod 4 in the water area under the action of the counterweight block 701, and has strong applicability.

[0054] Example 3: Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A rapid restoration ecological structure for degraded mangroves. Based on Example 2, further, an air guide plate 9 is provided on the top of the movable tube 8, and the bottom of the inner material tube 2 is rotatably connected to the positioning rod 4.

[0055] Furthermore, a bending and moving rod 10 is fixedly provided at the bottom of the inner material tube 2, and the bending and moving rod 10 moves in the silt layer 101 at the bottom of the water area 1 to be repaired.

[0056] Furthermore, the bending and pushing rod 10 includes an L-shaped connecting rod 12 fixedly connected to the positioning rod 4, a plurality of movable tubes 121 are sleeved on the L-shaped connecting rod 12, a coil spring is arranged between each movable tube 121 and the L-shaped connecting rod 12, and a pushing rod 122 is fixed on the movable tube 121.

[0057] Specifically, an air guide piece 9 is arranged on the top of the mobile tube 8. When the air guide piece 9 is blown by the wind, it drives the mobile tube 8 to rotate. The mobile tube 8 drives the material guide tube 3 to rotate through the telescopic rod 801. The material guide tube 3 drives the protective tube 5 and the inner material tube 2 connected thereto to rotate through the connecting tube 3011, thereby automatically adjusting the outflow range of the soil repair agent of the inner material tube 2, so that the soil repair range of the inner material tube 2 is more comprehensive, avoiding the repair dead corner, and effectively improving the repair effect of the mangrove wetland;

[0058] When the inner material tube 2 rotates, the bent and moved lever 10 moves the silt in the silt layer 101, so that gaps and channels appear between the silt layers 101, thereby facilitating the soil remediation agent flowing out of the inner material tube 2 to fully penetrate into the silt layer 101, and fully absorbing, transforming and degrading the organic pollutants in the silt layer 101;

[0059] When the bending and pushing rod 10 may encounter plant roots or stones firmly fixed in the soil layer during rotation, when the pushing rod 122 is subjected to force, the movable tube 121 is stationary relative to the rotating L-shaped connecting rod 12, and automatically avoids the stones or plant roots to avoid affecting the normal loosening and through-hole action of the bending and pushing rod 10 as a whole on the silt.

[0060] Example 4: Reference Figure 1 , a rapid restoration ecological structure for degraded mangroves, based on Example 3, further includes a fence structure 11, the fence structure 11 is arranged at the edge of the water area 1 to be restored, the fence structure 11 includes artificial fences and / or ecological fences, the artificial fences include sandbags or mud bags, and the ecological fences are made of wooden piles or oyster shells.

[0061] Specifically, artificial fences or ecological fences are set up around the water area 1 to be restored, so as to intercept garbage around the sea area outside the mangrove area. The multiple fence structures 11 form an ecological barrier to intercept garbage, further restore the ecological structure of mangroves, ensure the normal growth of plants, purify the mangrove wetlands, and play a role in treating both the symptoms and the root causes.

[0062] Working principle: The staff evenly inserts multiple positioning rods 4 into the silt layer 101 in the water area 1 to be repaired, especially near the mangrove plants, so that multiple inner material tubes 2 are evenly distributed in the water area 1 to be repaired. Two adjacent inner material tubes 2 are connected by the guide tube 3. When no repair work is being carried out, the protective tube 5 blocks the first through hole 201 of the inner material tube 2 to prevent silt and impurities in the water body from entering the inner material tube 2, causing the inner material tube 2 to be blocked, affecting the subsequent repair and use of the inner material tube 2;

[0063] A casing 7 is sleeved on the outer side of the protection pipe 5, and the bottom of the casing 7 is placed on the surface of the silt layer 101 through a counterweight block 701. The counterweight block 701 has a certain weight to prevent the pipe body from being displaced under the impact of the water body. The casing 7 shields the part of the pipe body of the protection pipe 5 placed on the surface of the silt layer 101;

[0064] When performing the repair work, the water pump 13 is controlled to run, and the water pump 13 extracts the soil repair agent in the soil repair agent box 131 and transports it to the metal pipe 301 through the guide pipe 3. The soil repair agent drives the toggle plate 603 through the guiding effect of the guide block 3012. The toggle plate 603 drives the protection tube 5 to rotate through the rotating shaft 601, so that the protection tube 5 rotates relative to the inner material tube 2. The second through hole 501 of the protection tube 5 is aligned with the first through hole 201 of the inner material tube 2. The soil repair agent in the metal tube 301 enters the inner material tube 2 through the connecting pipe 3011 and flows out through the through hole. When the outflowing soil repair agent impacts outward to repair the wetland water body and silt, it can also limit external substances from entering the inner material tube 2 through the through hole, so as to ensure the continuous repair and use of the inner material tube 2. The soil repair agent repairs the soil while providing the mangrove plants with the elements required for growth;

[0065] An air guide piece 9 is arranged on the top of the mobile tube 8. When the air guide piece 9 is blown by wind, it drives the mobile tube 8 to rotate. The mobile tube 8 drives the material guide tube 3 to rotate through the telescopic rod 801. The material guide tube 3 drives the protective tube 5 and the inner material tube 2 connected thereto to rotate through the connecting tube 3011, thereby automatically adjusting the outflow range of the soil remediation agent of the inner material tube 2, so that the soil remediation range of the inner material tube 2 is more comprehensive, avoiding the occurrence of repair dead corners;

[0066] When the inner material tube 2 rotates, the bent and moved lever 10 moves the silt in the silt layer 101, so that gaps and channels appear between the silt layers 101, thereby facilitating the soil remediation agent flowing out of the inner material tube 2 to fully penetrate into the silt layer 101, and fully absorbing, transforming and degrading the organic pollutants in the silt layer 101;

[0067] When the bending and moving rod 10 may encounter plant roots or stones firmly fixed in the soil layer during the rotation process, when the lever 122 is subjected to force, the movable tube 121 is stationary relative to the rotating L-shaped connecting rod 12, and automatically avoids the stones or plant roots, so as to avoid affecting the normal loosening and through-hole action of the bending and moving rod 10 as a whole for the silt;

[0068] The present invention facilitates the uniform transportation of soil remediation agents into the silt layer 101 through a plurality of inner material pipes 2, so that the soil remediation agents can effectively repair and treat silt at different heights in the water area, absorb, transform and degrade organic pollutants, and have good economic, social and ecological benefits; at the same time, the inner material pipes 2 use a vertical plug-in method instead of being buried in the water and soil, which is convenient for timely treatment of the inner material pipes 2 when they are damaged.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
