Description

Technical Field

[0001] This application relates to the technical field of ecological slope protection, and in particular to a river channel vegetated ecological slope protection method and construction method. Background Technology

[0002] Ecological slope protection is a slope protection technique that integrates basic knowledge from disciplines such as engineering mechanics, soil science, ecology, and botany to support slopes or side slopes, forming a comprehensive slope protection system composed of plants or a combination of engineering and plants. After the slope is excavated, vegetation is planted, and the interaction between the plants and the rock and soil (root anchoring effect) is used to protect and reinforce the surface of the slope. This method not only meets the requirements for the stability of the slope surface but also restores the damaged natural ecological environment, making it an effective means of slope protection and stabilization.

[0003] Currently, the most common ecological slope protection along riverbanks is vegetated concrete ecological slope protection. This type of protection involves appropriately mixing concrete aggregates with specialized ecological slope protection admixtures and pouring the mixture on-site to form a complete ecological slope protection system suitable for planting and greening. It features high strength, high porosity, structural stability, good freeze-thaw resistance, and effective suppression of soil erosion. It is also adaptable to various planting methods, achieving a green coverage rate of over 95%, improving the ecological environment and landscape, and enabling long-term sustainable ecological slope protection.

[0004] An existing type of plant-based concrete ecological slope protection is shown in the attached figure. Figure 1 As shown, it includes a slope 1 with several planting troughs 11 for filling soil and planting greenery; it also includes several enclosure flanges 12, which correspond one-to-one with the planting troughs 11. The enclosure flanges 12 enclose the corresponding planting troughs 11 to reduce soil erosion.

[0005] However, in the use of existing vegetated concrete ecological slope protection, the water required by the plants mainly comes from rainfall. When the rainfall is small, rainwater falling directly into the planting trough can be stored in the soil and absorbed by the plants, while other rainwater will flow directly into the river along the slope. Moreover, the soil is prone to insufficient water storage after rain, which affects the healthy growth of plants. When the rainfall is large, in addition to rainwater falling directly into the planting trough, rainwater from the bank can also flow down the slope into the planting trough. However, excessive water can easily cause waterlogging damage to the plants, and the impact of the water flow on the plants will affect the growth direction of the plants, which is also not conducive to their healthy growth. Summary of the Invention

[0006] This application provides a riverbank vegetation-based ecological slope protection method and construction method, which enables plants to grow healthily under sufficient water conditions, thereby making the ecological slope protection effective and stable in protecting and stabilizing the slope.

[0007] On the one hand, this application provides a river channel vegetated ecological slope protection method, which adopts the following technical solution:

[0008] A riverbank vegetation-type ecological slope protection includes a slope body and several retaining flanges. The slope body has several planting troughs, and the retaining flanges are disposed on the slope body, enclosing the planting troughs. It also includes several drainage channels, several first filters, several infiltration pipes, and several first water-absorbing components. A water collection trough is formed at the top of the slope body, and a confluence trough is formed at the bottom of the slope body. Several drainage outlets are also formed at the bottom of the slope body, with one end of each outlet connected to the confluence trough and the other end opening towards the river. The drainage channels are located inside the slope body, with several planting troughs distributed on both sides of the drainage channels. The two ends of the drainage channels are respectively connected to the water collection trough and the... The confluence channels are interconnected; both the water collection channel and the confluence channel form openings on the slope; several first filter elements are disposed on the slope and cover the openings of the water collection channel and the confluence channel; several infiltration pipes are disposed in the several planting troughs, and several infiltration holes are opened on the infiltration pipes; one end of some of the infiltration pipes is connected to the water collection channel, and one end of the remaining infiltration pipes is connected to the confluence channel; several first water-absorbing elements correspond one-to-one with the several infiltration pipes; one end of several first water-absorbing elements is located in the infiltration pipes; the other end of some first water-absorbing elements is located in the water collection channel; and the other end of the remaining first water-absorbing elements is located in the confluence channel.

[0009] By adopting the above technical solution, during rainfall, rainwater falling directly into the planting troughs can be stored in the soil and absorbed by plants. Some of the rainwater will be discharged into the river through a collection trough, several drainage channels, a confluence trough, and several drainage outlets. A small portion of the rainwater falling directly onto the slope will flow directly into the river along the slope. When the rainfall is small, the water remaining in the collection trough and confluence trough can enter several planting troughs through several first water-absorbing components to supplement the water for plant growth. When the rainfall is large, the rainwater on the bank will flow towards the slope and enter the collection trough, thereby reducing the amount of rainwater flowing directly down the slope and thus reducing the impact of excessive water flow on plant growth. This allows plants to grow healthily with sufficient water, thus enabling the ecological slope protection to effectively and stably protect and stabilize the slope.

[0010] Optionally, it also includes several second filters with a filtration accuracy greater than that of the first filter. Water storage tanks are provided at the top and bottom of the slope. The two water storage tanks are located below the water collection tank and the water confluence tank, respectively, and are connected to both the water collection tank and the water confluence tank. The several second filters cover the connection between one water storage tank and the water collection tank, and the connection between the other water storage tank and the water confluence tank. The end of the first water-absorbing element away from the corresponding seepage pipe passes through the corresponding second filter and is located in the corresponding water storage tank.

[0011] By adopting the above technical solution, the first filter element can filter out larger impurities (such as leaves, packaging paper, etc.) that move with the rainwater flow, reducing the probability of larger impurities entering the water collection tank and causing blockage, thereby enabling the drainage channel to stably guide the flow of rainwater; the second filter element can filter out smaller impurities that enter the water collection tank, reducing the probability of smaller impurities entering the water storage tank; the water storage tank can increase the amount of rainwater remaining in the water collection tank and the confluence tank, so that when the plants need to replenish water, the several first water-absorbing elements can release water from the water storage tank into the soil in the planting trough, thereby enabling the several first water-absorbing elements to stably replenish water for the plants.

[0012] Optionally, the first filter element has a plurality of extension rods extending in the same direction. When the first filter element covers the opening of the water collection tank, the plurality of extension rods are located in the water collection tank. The ends of the extension rods abut against the second filter element, and the end of the first water-absorbing element away from the seepage pipe passes through the space between adjacent extension rods and enters the water storage tank.

[0013] By adopting the above technical solution, when small impurities pass through the first filter element and enter the water collection tank, several extension rods can intercept the impurities, preventing them from continuing to move along the rainwater flow after entering the water collection tank, thereby further reducing the probability of blockage after the impurities enter the water collection tank; at the same time, several extension rods can also support the first filter element, improve the structural strength of the first filter element, reduce the impact of external forces (such as stepping) on ​​the first filter element, thereby extending the service life of the first filter element.

[0014] Optionally, the extension rod has a plurality of protrusions evenly distributed along its extension direction. When the end of the first water-absorbing member away from the seepage pipe passes between adjacent extension rods, the first water-absorbing member abuts against the plurality of protrusions and is clamped and positioned.

[0015] By adopting the above technical solution, during the process of several extension rods intercepting impurities, several protrusions can enhance the interception effect of the extension rods on impurities, making it more difficult for impurities entering the water collection tank to move with the rainwater flow. Moreover, the staff can remove the first filter element to carry away the impurities intercepted by the extension rods, which is convenient for impurity cleaning. At the same time, when the ends of several first water suction elements are installed, they can be positioned with the help of several protrusions on the extension rods, thereby improving the positional stability of the end of the first water suction element away from the seepage pipe, so that the end of the first water suction element can be kept in the water storage tank, thereby reducing the probability that the end of the first water suction element will leave the water storage tank due to the flow of rainwater.

[0016] Optionally, it also includes a number of guide members, all of which are disposed inside the drainage channel; each pair of guide members forms a group, and the groups of guide members are distributed at equal intervals along the drainage direction of the drainage channel, with the two guide members in the same group constricting towards the bottom of the slope.

[0017] By adopting the above technical solution, when rainwater enters the collection trough and flows into the drainage channel, several guide members are arranged in pairs and narrow towards the bottom of the slope. When the rainwater passes between the two guide members, water pressure is generated, which drives the rainwater to pass through quickly, thereby accelerating the speed at which the rainwater flows through the drainage channel. When the rainfall is heavy, the rainwater on the bank can be discharged into the river channel quickly and in a timely manner through the collection trough, several drainage channels, the confluence trough, and several drainage outlets. This further reduces the probability that the rainwater on the bank will flow down the slope due to insufficient drainage, thus affecting plant growth.

[0018] Optionally, it also includes several limiting members, which are respectively disposed on both sides inside the drainage channel; two adjacent limiting members on the same side form a group, and the several groups of limiting members correspond one-to-one with the several flow guides; the flow guides are rotatably connected to the drainage channel, and the rotation axis of the flow guides is perpendicular to the slope surface of the slope and close to its own middle position; the two limiting members in a group restrict the rotation range of the flow guides; several through holes are opened on the slope, and the two ends of the through holes are respectively connected to the planting trough and the drainage channel, and the through holes are located between two limiting members in the same group.

[0019] By adopting the above technical solution, under natural conditions and when rainfall is low, the same set of guide components rotates to abut against a corresponding limiting component and widens towards the bottom of the slope. At this time, the speed of rainwater flowing through the drainage channel decreases, and the rainwater can enter the planting trough through the through holes under the guidance of the guide components to replenish water for plant growth. When rainfall is high, i.e., when the water flow through the drainage channel is large, the same set of guide components rotates to abut against another corresponding limiting component and narrows towards the bottom of the slope. At this time, the speed of rainwater flowing through the drainage channel increases, and the guide components can reduce the amount of rainwater entering the planting trough through the through holes, thereby further reducing the probability of plants being affected by waterlogging.

[0020] Optionally, it also includes a plurality of third filter elements, each corresponding to one of the plurality of through holes, the third filter elements covering the connection between the through holes and the drainage channel; the end of the guide near the through hole has a blockage clearing part, and the blockage clearing part contacts the third filter element during the rotation of the guide.

[0021] By adopting the above technical solution, the third filter element can intercept impurities, thereby reducing the probability of impurities entering the through holes and causing blockages, so that rainwater can smoothly enter the planting trough through the through holes to replenish water for plant growth; at the same time, when impurities adhere to the third filter element, the clearing part can scrape them off during the rotation of the guide element, thereby reducing the probability of the third filter element becoming blocked.

[0022] Optionally, it also includes a plurality of second water-absorbing elements, which correspond one-to-one with the plurality of through holes, and the second water-absorbing elements fill the through holes; when the guide element abuts against a limiting element under its own weight, a water storage space is formed between the guide element and the inner sidewall of the drainage channel, and the water storage space communicates with the corresponding through hole.

[0023] By adopting the above technical solution, when the water flow in the drainage channel is small, the same set of guide components will be flared towards the bottom of the slope, so that a water storage space is formed between the guide components and the side wall of the drainage channel. The water storage space can store a certain amount of rainwater. The second water suction component can suck the rainwater in the water storage space into the planting trough according to the needs of plant growth, thereby further ensuring that the plants can grow healthily under sufficient water conditions.

[0024] Optionally, the drainage channel has a constriction structure at one end near the top of the slope, and the constriction structure guides the rainwater flow to contact the end of the guide member away from the through hole.

[0025] By adopting the above technical solution, during the process of rainwater entering the collection tank and flowing into the drainage channel, the constriction structure can guide the rainwater into the drainage channel, so that the rainwater contacts the end of the guide component away from the corresponding through hole during the process of flowing through the drainage channel. This makes it easier to use the flow of rainwater to drive the guide component to rotate, and improves the stability and reliability of the process of the guide component rotating according to the size of the water flow.

[0026] On the other hand, this application also provides a construction method, which adopts the following technical solution:

[0027] A construction method for constructing the aforementioned riverbank vegetation-based ecological slope protection, comprising the following specific steps:

[0028] Several drainage channels and several seepage pipes are pre-positioned on the riverbank using steel reinforcement frames.

[0029] The slope is formed by pouring concrete, and several planting troughs, water collection troughs and confluence troughs are left during the pouring process;

[0030] Several drainage outlets are provided at the bottom of the slope.

[0031] Install several of the first water-absorbing components;

[0032] Install several of the first filter elements to cover the openings of the water collection tank and the confluence tank;

[0033] Soil is filled into several of the planting troughs and suitable plants are planted.

[0034] In summary, this application includes at least one of the following beneficial effects:

[0035] 1. It enables plants to grow healthily in a state of sufficient water, thereby making ecological slope protection effective and stable in protecting and stabilizing slopes;

[0036] 2. It can reduce the probability of impurities entering the water collection tank and causing blockages, so that rainwater on the bank can smoothly flow into the river through the drainage channel;

[0037] 3. It can automatically adjust the flow rate of rainwater in the drainage channel according to different rainfall amounts, thereby reducing the impact of different rainfall weather on the healthy growth of plants;

[0038] 4. The plants in the planting trough can absorb rainwater from the water storage tank and the water storage space according to their own needs through several first water suction devices and several second water suction devices, which facilitates the healthy growth of the plants.

[0044] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0045] Reference Figure 2 and Figure 3 This application discloses a riverbank vegetation-type ecological slope protection, including a slope body 1, several drainage channels 2, and several first water-absorbing components 3. The slope body 1 is located on one side of the river, with an inclined slope surface, and has several planting troughs 11 on the slope surface for filling with soil and planting plants; the drainage channels 2 are all located inside the slope body 1, and rainwater from the bank flows towards the slope body 1, first flowing into the interior of the slope body 1 and then through the drainage channels 2 to finally drain into the river; the two ends of the several first water-absorbing components 3 are located at the planting troughs 11 and inside the slope body 1, respectively, and rainwater inside the slope body 1 can enter the soil in the planting troughs 11 through the first water-absorbing components 3 to provide soil for plant growth. When the rainfall is insufficient to meet the water needs of plant growth, the first water-absorbing components 3 can replenish the rainwater in the slope body 1 into the planting troughs 11; when the rainfall is too heavy and the rainwater from the bank flows down the slope body 1, the rainwater will enter the interior of the slope body 1 and flow along the drainage channels 2 to finally drain into the river, thereby reducing the impact of water flow on plant growth.

[0046] Reference Figure 2The slope 1 has platform structures 13 at both its top and bottom, and the two ends of the slope surface of the slope 1 are respectively connected to the two platform structures 13. A number of planting troughs 11 are evenly distributed along the edge trajectory of the slope 1 on the slope surface, and also evenly distributed along the slope's inclination direction. In this embodiment, preferably, the planting troughs 11 are divided into two rows on the slope surface of the slope 1, with the two rows of planting troughs 11 respectively close to the two platform structures 13. For ease of illustration, only a portion of the ecological slope protection is shown in the accompanying drawings.

[0047] The slope 1 has several retaining flanges 12 on its surface, each corresponding to a planting trough 11. The retaining flanges 12 extend outwards along a direction perpendicular to the slope surface, enclosing the planting troughs 11 along their edges. After soil is filled into the planting troughs 11 and plants are planted, the retaining flanges 12 prevent rainwater flowing along the slope surface from directly entering the planting troughs 11, effectively reducing the probability of waterlogging and plant death. Simultaneously, the retaining flanges 12 effectively reduce soil erosion during rainfall, ensuring healthy plant growth in the planting troughs 11.

[0048] Reference Figure 2 and Figure 4 The slope 1 has a water collection trough 14 along its edge on the platform structure 13 at its top, and a confluence trough 15 along its edge on the platform structure 13 at its bottom. Both the water collection trough 14 and the confluence trough 15 penetrate the top of the platform structure 13 to form an opening. The drainage channel 2 is a square pipe structure buried inside the slope 1. The length of the drainage channel 2 is parallel to the slope direction of the slope 1, and several planting troughs 11 are symmetrically distributed on both sides of each drainage channel 2. The two ends of the drainage channel 2 are connected to the water collection trough 14 and the confluence trough 15, respectively. The slope 1 also has several drainage outlets 16 along the horizontal direction on the platform structure 13 at its bottom. The drainage outlets 16 are evenly distributed along the edge of the slope 1. One end of the drainage outlet 16 is connected to the confluence trough 15, and the other end of the drainage outlet 16 leads to the river channel. Rainwater on the bank flows towards slope 1, first entering the collection trough 14, then flowing through several drainage channels 2 into the confluence trough 15, and finally discharging into the river channel through several drainage outlets 16. In this embodiment, preferably, the two ends of the inner wall of the bottom of the drainage channel 2 are connected to the bottom wall of the collection trough 14 and the bottom wall of the confluence trough 15, respectively, and the bottom wall of the drainage outlet 16 is connected to the bottom wall of the confluence trough 15, so as to facilitate the thorough discharge of rainwater along the above path.

[0049] In this embodiment, to reduce the entry of external impurities into the confluence channel 15 through the drain outlet 16, thereby reducing the probability of blockage of the drain outlet 16 or the confluence channel 15 due to impurities, filter screens 4 are fixedly installed on the slope 1 at the openings of several drain outlets 16 near the river channel. Since the filter screen 4 is a common existing technology, it will not be described in detail here.

[0050] Furthermore, the riverbank vegetation-type ecological slope protection also includes several first filter elements 5. Each first filter element 5 has a plate-like structure and several filter holes for filtering garbage larger than a certain size (in practical applications, the size of the filter holes on the first filter element 5 can be freely adjusted according to needs). Several first filter elements 5 are placed on the openings at the top of the water collection tank 14 and the confluence tank 15, with adjacent first filter elements 5 arranged in sequence with their width sides abutting each other. Applying upward force to the first filter elements 5 allows them to be removed.

[0051] The slope 1 is provided with water storage tanks 17 in the platform structure 13 at the top and bottom. The water storage tanks 17 extend towards both ends along the edge trajectory of the slope 1. The two water storage tanks 17 are located below the water collection tank 14 and the confluence tank 15, respectively. The water storage tanks 17 are connected to the corresponding water collection tank 14 or the corresponding confluence tank 15 and the connection openings face upwards.

[0052] The riverbank vegetation-type ecological slope protection also includes several second filter elements 6. Each second filter element 6 is also a plate-like structure, and the first filter element 5 also has several filter holes for filtering debris smaller than a certain size (in practical applications, the size of the filter holes on the second filter element 6 can be freely adjusted according to needs). Several second filter elements 6 are placed over the opening at the top of the water storage tank 17, with adjacent second filter elements 6 arranged in abutting position along their width sides. Applying upward force to the second filter elements 6 allows them to be removed.

[0053] After the rainwater on the bank flows towards the slope 1, it passes through several first filters 5 and enters the collection tank 14. The first filters 5 located at the top of the slope 1 can intercept larger impurities (such as leaves, packaging bags, etc.) that move with the rainwater flow, reducing the probability of larger impurities entering the collection tank 14. Subsequently, several second filters 6 located at the top of the slope 1 can intercept smaller impurities that enter the collection tank 14 with the rainwater, reducing the probability of smaller impurities entering the storage tank 17, thereby enabling the storage tank 17 located at the top of the slope 1 to retain a certain amount of relatively pure rainwater after the rain.

[0054] After rainwater falls directly onto the slope surface of slope 1, as it flows down the slope, several first filters 5 located at the bottom of slope 1 can intercept larger impurities washed to the bottom of slope 1 by the rainwater, reducing the probability of these larger impurities entering the collection channel 15. Subsequently, several second filters 6 located at the bottom of slope 1 can intercept smaller impurities that enter the collection channel 15 with the rainwater, reducing the probability of these smaller impurities entering the water storage tank 17. This allows the water storage tank 17 at the bottom of slope 1 to retain a certain amount of relatively pure rainwater after the rain.

[0055] To reduce the occurrence of impurities being washed directly into the river by rainwater, it is preferable that the platform structure 13 at the bottom of the slope 1 has a retaining structure 18 on the side closest to the river. The retaining structure 18 not only intercepts impurities, but also facilitates the subsequent cleaning of impurities located at the bottom of the slope 1 by cleaning personnel.

[0056] Reference Figure 4 Furthermore, one side of the first filter element 5 extends outward in a direction perpendicular to its own plane with several extension rods 51. The extension rods 51 are cylindrical in shape. The positions of the extension rods 51 on the first filter element 5 are staggered with the positions of the filter holes on the first filter element 5, and the spacing between adjacent extension rods 51 is equal.

[0057] After several first filter elements 5 and several second filter elements 6 are installed on the slope 1, the ends of several extension rods 51 on the same filter element that are away from the first filter element 5 abut against the corresponding second filter element 6 and the bottom wall of the water collection tank 14. That is, the several extension rods 51 support the first filter element 5, thereby improving the load-bearing capacity of the first filter element 5 and extending its service life. At the same time, when impurities pass through the filter holes on the first filter element 5 and enter the water collection tank 14 or the confluence tank 15, the several extension rods 51 can intercept the impurities, effectively preventing the impurities from continuing to move with the rainwater flow, thereby reducing the probability of impurities entering the drainage channel 2 with the rainwater or moving towards the drain outlet 16 with the rainwater.

[0058] Furthermore, the extension rod 51 has a plurality of protrusions 511 evenly distributed along its own axis, preferably the protrusions 511 having an overall spherical structure. The plurality of protrusions 511 can improve the extension rod 51's ability to intercept impurities, and at the same time, since the surface of the protrusions 511 with the spherical structure is smooth, it can reduce the probability of impurities forming blockages at the plurality of extension rods 51.

[0059] Furthermore, the riverbank vegetation-type ecological slope protection also includes several infiltration pipes 7 for easy installation of the first water-absorbing component 3. Preferably, the infiltration pipes 7 are circular tubular structures, and the several infiltration pipes 7 correspond one-to-one with several planting troughs 11 on the slope 1. The infiltration pipes 7 are located in the planting troughs 11, the axis of the infiltration pipes 7 is parallel to the slope surface of the slope 1, and the position of the infiltration pipes 7 in the corresponding planting troughs 11 is centered.

[0060] For several seepage pipes 7 located near the top of the slope 1, one end is fixedly connected to the wall of the planting trough 11 away from the top of the slope 1, and the other end extends obliquely upward and passes through the slope 1 to communicate with the water collection trough 14; for several seepage pipes 7 located near the bottom of the slope 1, one end is fixedly connected to the wall of the planting trough 11 away from the bottom of the slope 1, and the other end extends obliquely downward and passes through the slope 1 to communicate with the confluence trough 15. The portion of the seepage pipe 7 located in the planting trough 11 has several seepage holes 71, which allow the interior of the seepage pipe 7 to communicate with the planting trough 11.

[0061] The first absorbent element 3 is a strip structure with a circular cross-section. The first absorbent element 3 is absorbent and flexible. In this embodiment, the first absorbent element 3 is preferably a sponge strip. In other embodiments, the first absorbent element 3 can also be a cotton strip, etc.

[0062] A number of first water-absorbing elements 3 correspond one-to-one with a number of seepage pipes 7. One end of the first water-absorbing element 3 enters the seepage pipe 7 and fills the interior of the seepage pipe 7, while the other end is located in the water collection tank 14 or the confluence tank 15. For the end of the first water-absorbing element 3 that is away from the seepage pipe 7, some of the second filter elements 6 have pre-reserved perforations 61 for it to pass through. After entering the water collection tank 14 or the confluence tank 15, it will pass through the corresponding second filter element 6 through the corresponding perforation 61 and abut against the bottom wall of the corresponding water storage tank 17.

[0063] Furthermore, preferably, after the end of the first water-absorbing component 3 furthest from the seepage pipe 7 enters the water collection tank 14 or the confluence tank 15, it first passes through the gap between several adjacent extension rods 51 on the first filter component 5, and then passes through the perforation 61 into the water storage tank 17; and after the first water-absorbing component 3 passes through the gap between the adjacent extension rods 51, the periphery of the first water-absorbing component 3 will simultaneously abut against the four protrusions 511 on the two adjacent extension rods 51, so that the position of the first water-absorbing component 3 in the water collection tank 14 or the confluence tank 15 is relatively stable after the first water-absorbing component 3 is installed, reducing the influence of rainwater flow on its positional stability, so that the first water-absorbing component 3 can stably play the role of water absorption.

[0064] After rainfall, the water storage tank 17 at the top and bottom of the slope 1 will retain a certain amount of rainwater. When the soil moisture content in the planting trough 11 is lower than a certain level (i.e., the plants do not need enough water), the rainwater in the water storage tank 17 can enter the soil through the corresponding first water absorption device 3, keeping the soil moist and thus replenishing water for the healthy growth of the plants.

[0065] Reference Figure 3 Furthermore, the riverbank vegetation ecological slope protection also includes several guide members 21, which are installed inside several drainage channels 2. In this embodiment, preferably, four guide members 21 are installed inside each drainage channel 2. The guide members 21 are generally plate-shaped structures, with two guide members 21 forming a group. The two guide members 21 in the same group are located near the inner walls on both sides of the drainage channel 2. The two groups of guide members 21 are evenly distributed along the length of the drainage channel 2, and each group of guide members 21 is located between different adjacent planting troughs 11.

[0066] The plane of the guide member 21 is perpendicular to the slope surface of the slope 1. When rainwater forms a large flow and enters the drainage channel 2, each set of guide members 21 can narrow towards the bottom of the slope 1. When rainwater flows between two guide members 21 of the same set, the water pressure and the flow velocity increase due to the gradually decreasing flow area, resulting in a narrowing phenomenon. This allows the water to flow into the confluence channel 15 in a timely manner and finally be discharged through several drainage outlets 16.

[0067] Furthermore, the guide member 21 is rotatably connected to the drainage channel 2, the rotation axis of the guide member 21 is perpendicular to the slope surface of the slope 1, and the rotation axis of the guide member 21 is close to the middle position of the guide member 21.

[0068] The riverbank vegetation ecological slope protection also includes several limiting members 22 for limiting the rotation range of the guide member 21. Several limiting members 22 are fixedly installed on the inner walls of both sides of several drainage channels 2. In this embodiment, since each guide member 21 requires a set of limiting members 22 (i.e., two limiting members 22) to limit its own rotation range, a total of eight limiting members 22 are installed in each drainage channel 2 (four on each inner wall).

[0069] On the slope 1, through holes 19 are provided between the drainage channel 2 and the adjacent planting trough 11 to connect the two. The river vegetated ecological slope protection also includes several third filter elements 8, which also have several filter holes (not shown in the attached figure) to filter out small impurities. The several third filter elements 8 correspond one-to-one with the several through holes 19. The third filter elements 8 are fixedly installed at the end of the corresponding through hole 19 near the adjacent drainage channel 2, thereby reducing the probability of small impurities entering the through hole 19 from the drainage channel 2.

[0070] The through-hole 19 is located on the slope 1 between two limiting members 22 in the same group. When there is no rainwater flowing through the drainage channel 2 or the amount of rainwater flowing through is small, the guide member 21 will rotate under its own gravity until its end near the adjacent through-hole 19 abuts against the corresponding lower limiting member 22. At this time, the two guide members 21 in the same group are flared towards the bottom of the slope 1. When rainwater flows through the two guide members 21 in the same group, a flow expansion phenomenon will occur. As the area through which the water flows increases, the water pressure and the speed of the water flow decrease, and even backflow may occur, resulting in vortex formation and loss of kinetic energy, thereby prolonging the time for rainwater to flow through the drainage channel 2. When rainwater flows through the drainage channel 2 at a lower speed, some rainwater can flow towards the through-hole 19 under the guidance of the guide member 21, so that some rainwater can enter the soil in the planting trough 11 through the through-hole 19, supplementing water for the healthy growth of plants.

[0071] When the amount of rainwater flowing through the drainage channel 2 is large, the end of the guide member 21 furthest from the adjacent through hole 19 experiences a greater impact force from the water flow. This allows it to overcome its own weight and rotate until the end closest to the adjacent through hole 19 abuts against the corresponding upper limiting member 22. At this point, the two guide members 21 in the same group converge towards the bottom of the slope 1, causing a narrowing phenomenon when rainwater flows between them. The guide member 21 guides the rainwater to flow quickly through the drainage channel 2, while reducing the amount of rainwater flowing into the planting trough 11 through the through hole 19. This facilitates the timely discharge of rainwater flowing from the bank towards the slope 1 through the drainage channel 2 and ultimately from several drainage outlets 16, thereby reducing the impact of rainwater flowing down the slope 1 into the planting trough 11 on the healthy growth of plants.

[0072] Furthermore, the end of the flow guide 21 near the adjacent through hole 19 has a cleaning part 211. During the rotation of the flow guide 21, the cleaning part 211 abuts against the two limiting members 22 respectively, thereby limiting the rotation range of the flow guide 21. The cleaning part 211 is elastic and can be bent and deformed. Preferably, the cleaning part 211 is made of rubber. During the rotation of the flow guide 21, the cleaning part 211 can contact the surface of the adjacent third filter element 8, thereby cleaning the surface of the third filter element 8 and further reducing the probability of impurities forming a blockage on the surface of the third filter element 8.

[0073] Furthermore, the riverbank vegetation-type ecological slope protection also includes several second water-absorbing components 9, each corresponding to a number of through holes 19. The second water-absorbing components 9 are installed in the corresponding through holes 19 and fill the corresponding through holes 19. In this embodiment, it is preferable that both the second water-absorbing components 9 and the first water-absorbing components 3 are sponge strips.

[0074] The preferred guide member 21 is attached to the two inner walls of the drainage channel 2 on both sides along the rotation axis. When the end of the guide member 21 near the adjacent through hole 19 abuts against the corresponding lower limiting member 22, the side of the guide member 21 near the adjacent through hole 19 and the inner wall surface of the drainage channel 2 will form a water storage space 24. When rainwater flows through the drainage channel 2, some rainwater will remain in the water storage space 24, and the water storage space 24 is connected to the through hole 19.

[0075] At this time, when the soil moisture content in the planting trough 11 is still low (i.e., the water required for plant growth is still insufficient), the rainwater in the water storage space 24 can enter the soil in the planting trough 11 through the corresponding second water-absorbing element 9 to replenish the water for healthy plant growth.

[0076] Furthermore, to ensure that rainwater flows from the collection trough 14 into the drainage channels 2, it is concentrated in the middle of the drainage channels 2, facilitating contact between the rainwater and the ends of the guide members 21 away from the unblocking section 211 as it flows through the drainage channels 2. This allows the rainwater to smoothly drive the guide members 21 to rotate and abut against the corresponding upper limiting members 22 when the flow rate reaches a certain level. The drainage channel 2 has a constriction structure 23 at its end near the collection trough 14. After entering the drainage channel 2 through the constriction structure 23, the rainwater in the collection trough 14 is concentrated in the middle of the drainage channel 2 and flows down.

[0077] The implementation principle of a river channel vegetation-based ecological slope protection method in this application embodiment is as follows:

[0078] During rainy weather, rainwater on the bank will flow through several first filters 5 into the water collection tank 14, then through several drainage channels 2 into the confluence tank 15, and finally through several drainage outlets 16 into the river. After rainfall, a certain amount of rainwater will remain in the water storage tanks 17 at the top and bottom of the slope 1. When the plants in the planting trough 11 need to replenish water, the rainwater in the water storage tank 17 can enter the soil in the corresponding planting trough 11 through several first water absorption components 3.

[0079] When the rainfall is small, several guide components 21 will be in a state that causes the rainwater flowing through the drainage channel 2 to narrow, reducing the speed of the rainwater flowing through the drainage channel 2, and allowing the rainwater to enter several water storage spaces 24 for storage. After the rain, when the plants need to replenish water, the rainwater in the water storage space 24 can also enter the soil in the corresponding planting trough 11 through the corresponding second water absorption component 9.

[0080] When the rainfall is heavy, several guide components 21 will rotate under the action of the rainwater flow to a state that causes the rainwater flowing through the drainage channel 2 to expand, thereby speeding up the speed at which the rainwater on the bank flows towards the slope 1 and is discharged. This reduces the probability that the rainwater will flow down the slope 1 and directly into the planting trough 11. It also reduces the amount of rainwater entering the planting trough 11 through the through hole 19, thereby effectively reducing the probability of waterlogging damage to plants.

[0081] This application discloses a construction method for constructing the above-mentioned riverbank vegetation ecological slope protection, the specific steps of which are as follows:

[0082] S1. Pre-treat the slopes on both sides of the river channel.

[0083] The slopes on both sides of the river channel were leveled, compacted, and reinforced to ensure that the slope inclination and flatness met the required standards.

[0084] S2, Several drainage channels 2 and several seepage pipes 7 are pre-positioned on the river slope by steel reinforcement.

[0085] After fixing and installing several guide components 21, several limiting components 22 and several third filter components 8 on several drainage channels 2, mark the installation positions of several drainage channels 2 and several seepage pipes 7 on the slopes of both sides of the river. Then build a steel frame to fix the positions of several drainage channels 2 and several seepage pipes 7 on the slopes, thereby improving the overall structural strength after the ecological slope protection is formed.

[0086] S3. Pour concrete to form slope 1, and leave several planting troughs 11, water collection troughs 14 and confluence troughs 15 during the pouring process.

[0087] Using wooden boards, steel plates, and other materials as templates, and in conjunction with steel reinforcement frames, a space to be poured is formed with the same shape as the slope 1. Concrete is then poured into the space to be poured. After the concrete solidifies, a slope 1 with several planting troughs 11, water collection troughs 14, and confluence troughs 15 is formed.

[0088] S4. Water storage tanks 17 are opened at the top and bottom of the slope 1.

[0089] A water storage tank 17 is opened on the bottom wall of the water collection tank 14, and a water storage tank 17 is also opened on the bottom wall of the confluence tank 15. The corresponding second filter element 6 is arranged neatly to cover the openings of the two water storage tanks 17.

[0090] S5. Several drainage outlets 16 are opened at the bottom of the slope 1.

[0091] Several drainage outlets 16 are opened at the bottom of the slope 1, and filter screens 4 are fixedly installed at the openings of the drainage outlets 16 near the river channel.

[0092] S6. Install several first water-absorbing components 3 and several first filter components 5 to cover the openings of the two water storage tanks 17.

[0093] One end of the first water-absorbing element 3 is inserted into the corresponding seepage pipe 7 and the inside of the seepage pipe 7 is filled with the first water-absorbing element 3. The other end of the first water-absorbing element 3 is positioned by means of several extension rods 51 on the corresponding first filter element 5 and then passed through the corresponding second filter element 6 and placed in the water storage tank 17. At the same time, the installation of several first filter elements 5 is completed, so that several first filter elements 5 cover the opening of the water collection tank 14 and the opening of the confluence tank 15.

[0094] S7. Make several through holes 19 to connect the planting trough 11 with the drainage channel 2.

[0095] After the through hole 19 is opened, the interior of the drainage channel 2 is connected to the planting trough 11 through the third filter element 8 and the through hole 19. Then, the second water-absorbing element 9 is placed in the through hole 19 so that the second water-absorbing element 9 fills the through hole 19.

[0096] S8. Fill several planting troughs 11 with soil and plant suitable plants.

[0097] First, fill several planting troughs 11 with soil so that the soil covers the drainage pipes 7 and the through holes 19, and then plant the plants in the soil.

[0098] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
