Description

An ecological restoration bank protection structure Technical Field

[0001] The present invention relates to the technical field of water conservancy construction, and in particular to an ecological restoration bank protection structure. Background Art

[0002] Ecological restoration is a comprehensive approach to remediating polluted environments, guided by ecological principles and based on bioremediation. It combines various physical, chemical, and engineering measures to achieve optimal results and minimize costs through optimized combinations. The successful implementation of ecological restoration requires the involvement of multiple disciplines, including ecology, physics, chemistry, botany, microbiology, molecular biology, cultivation, and environmental engineering. The repair and maintenance of damaged ecosystems involves a variety of ecological theories, including ecological stability, ecological plasticity, and steady-state transformation.

[0003] For example, the Chinese patent document with publication number CN215819453U discloses a bank protection structure for ecological restoration of river and lake wetland outlets. During construction, a planting frame is placed in a flower pit, the fixing rod on the second planting frame is pulled and rotated, and the elastic rubber sleeve is compressed. The slot on the fixing rod is engaged with the support rod, and the convex slider is engaged with the convex slide groove to connect the planting frames. When adjusted to a certain position, the fixing rod is pulled and rotated, and then released. The elastic rubber sleeve will push the fixing rod to engage with the fixing slot. This can be repeated to fix the connection between multiple planting frames, and then the flowers can be planted in the planting frames.

[0004] However, the technical solution disclosed in the above patent document still has limitations in actual operation. Because when the planting frame is placed in the flower pit, although the planting frame will be connected to the embankment, the planting frames are abutted against each other (not completed by concrete pouring), and there are gaps between adjacent planting frames. Due to heavy rain or strong winds, the bottom of the planting frame is greatly impacted. When part of the soil at the bottom of the planting frame is washed away, holes appear at the bottom of the planting frame, which makes the bottom of the planting frame loose and greatly increases the probability of the planting frame sliding (or tilting) on ​​the embankment, affecting the use of the planting frame and the growth of plants.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] As shown in Figures 1 to 12, the present invention provides an ecological restoration revetment structure suitable for use on slope surfaces, comprising: a paving net 1, the paving net 1 being laid from the highest point of the slope to the lowest point of the slope, the surface of the paving net 1 having a plurality of planting holes 2; a plurality of sash blocks 3, all of which are detachably connected to the surface of the paving net 1, the sash blocks 3 having limiting holes 12, each limiting hole 12 on the sash block 3 corresponding to a set number of planting holes 2; a water retainer, the water retainer being fixedly disposed within the sash block 3, the water retainer being located at one end of the sash block 3 away from the lowest point of the slope; Among them, the water retainer has a plug-in part 4 and a blocking part 5. The width of the plug-in part 4 is equal to the width of the planting hole 2. The plug-in part 4 can be inserted into the slope along the planting hole 2. The blocking part 5 is connected to the end of the plug-in part 4 away from the slope and is located in the slattice block 3. The end surface of the blocking part 5 away from the plug-in part 4 exceeds the end surface of the slattice block 3 away from the plug-in part 4. The blocking part 5 can be pressed against the surface of the slope. When the plug-in part 4 is inserted into the slope, the blocking part 5 blocks and gathers water that spreads from the edge of the end of the slattice block 3 away from the low point of the slope and guides it to the surface of the laid net 1 on both sides of the slattice block 3.

[0043] The present invention can reinforce the slope surface and block water flow by cooperating with the laying net 1, the plug-in portion 4 and the barrier portion 5, so as to reduce the impact of water scouring on the slope surface. Specifically, the laying net 1 is directly laid from the upper part of the slope to the lower part of the slope (during the laying process, piles can be first driven into the slope with reference to FIG3 , and then the laying net 1 and the slope can be fixed). Thereafter, the sash block 3 is installed on the laying net 1 (the laying net 1 and the sash block 3 can be fixed with bolts or other components during installation). When the sash block 3 is installed, the plug-in portion 4 is guided to be inserted into the slope. At this time, the barrier portion 5 blocks and gathers water spreading from the edge of the end of the sash block 3 away from the lower part of the slope and guides it to the surface of the laying net 1 on both sides of the sash block 3.

[0044] In the present invention, the laying net 1 can preliminarily fix the entire slope to prevent the soil on the slope surface from collapsing and sliding significantly; at the same time, the formation of multiple planting holes 2 can plant plants, and after the plug-in part 4 is inserted into the planting hole 2, the soil in the planting hole 2 can be prevented from being washed away, thereby further reducing the impact of the scouring.

[0045] In some embodiments, the laying net 1 includes a plurality of water guide bars 6 and a plurality of shaping bars 7 laid from the upper part of the slope to the lower part of the slope, each shaping bar 7 is connected to all the water guide bars 6, and all the shaping bars 7 are perpendicular to the water guide bars 6, the planting holes 2 are arranged between adjacent water guide bars 6 and adjacent shaping bars 7, and the sash blocks 3 are connected to the shaping bars 7 by connecting members (the connecting members can be selected from bolts or other structures);

[0046] A water guide groove 8 is provided on the surface of each water guide bar 6 , and the water guide groove 8 can guide water to flow from the high part of the slope to the low part of the slope.

[0047] Since the water is discharged toward the surface of the laying net 1 on both sides of the lattice block 3, in order to prevent the water on the surface of the laying net 1 from accumulating in the planting hole 2, the water is gathered through the water guide trough 8 and discharged from the set position toward the set direction.

[0048] At the same time, the planting holes 2 are arranged between adjacent water guide strips 6 and adjacent shaping strips 7. The specific structure can be referred to Figures 1-3. After the water guide strips 6 and the shaping strips 7 are spliced ​​together, they will become a mesh structure.

[0049] In some embodiments, the plug-in portion 4 includes a fixed cover 9 and a blocking block 10 and a guide block 11 that can be inserted into the slope at the same time. The guide block 11 is arranged on the side of the blocking block 10 away from the limiting hole 12. The fixed cover 9 is arranged at the end of the blocking block 10 close to the laying net 1, and the end face of the fixed block is fixedly connected to the blocking block 10 and the guide block 11 at the same time. The fixed cover 9 is a hollow structure, and the end of the blocking portion 5 close to the plug-in portion 4 is inserted into the hollow cavity of the fixed cover 9 and fixedly connected to the fixed cover 9.

[0050] The structure of the sash block 3, the plug-in portion 4, and the barrier portion 5 in the present invention is shown in Figures 4 and 5. Two plug-in portions 4 and two barrier portions 5 are provided, and there is a gap between the two plug-in portions 4. A water guide bar 6 is located in the gap. The following is an example with reference to Figures 4 and 5:

[0051] Although the plug-in part 4 can be inserted into the slope along the planting hole 2, water can easily flow into the planting hole 2 from both sides of the plug-in part 4. Therefore, when the plug-in part 4 is inserted into the slope, the blocking block 10 is facing the water flow, and the guide block 11 will be on the side of the blocking block 10. Referring to Figures 3 and 4, when the water flow contacts the blocking block 10, a part of it will flow along the guide block 11 toward the side away from the center area of ​​the limiting hole 12 (that is, enter the water guide groove 8 on the water guide bar 6 on both sides of the sash block 3), and the other part will flow away from the water guide groove 8 on the water guide bar 6 in the gap. In this way, a large amount of water can be prevented from entering the area where the planting hole 2 is located from the contact point between the bottom of the laying net 1 and the slope.

[0052] In some embodiments, the barrier portion 5 includes an isolation strip 13 fixedly connected to the inner wall of the lattice block 3 and a water guide cover 14. The number of planting holes 2 corresponding to the end of the lattice block 3 close to the upper part of the slope is the same as the number of water guide covers 14.

[0053] The water outlet of the water guide cover 14 is located on the side surface of the water guide cover 14 away from the limiting hole 12. The side walls of the water guide strip 6 and the fixed cover 9 are provided with splicing grooves 15 at positions corresponding to the water outlet of the water guide cover 14.

[0054] The isolation strip 13 is fixedly connected to the water guide cover 14. There is a gap between the surface of the isolation strip 13 and the inner side wall of the end of the sash block 3 away from the lower part of the slope. A plurality of filter blocks 16 corresponding to the number of the water guide covers 14 are arranged in the gap. The surface of the water guide cover 14 has water inlets 17 at positions corresponding to the filter blocks 16.

[0055] A dirt storage groove 18 is provided on a surface of the filter block 16 on one side away from the water guide cover 14 , and a guide arc surface is provided on the surface of the filter block 16 at the edge of the dirt storage groove 18 .

[0056] In some embodiments, a guide bevel 19 is provided in the water guide cover 14 , and the guide bevel 19 can guide the water flowing into the water guide cover 14 to the water guide groove 8 .

[0057] Once the water flow is large, it cannot flow away quickly from the water guide groove 8 on the water guide bar 6, so water accumulation occurs at the high slope and in contact with the paving net 1. Once the water flow accumulates more, it will spread out from the end of the slat block 3 close to the high slope, and then the spreading water flow will carry some debris (such as sand or leaves, etc.) into the restriction hole 12. When the water flow enters, the water flow will first be blocked by the isolation bar 13, and then enter the water inlet 17 after being filtered by the filter block 16. At the same time, when the water flow is filtered, the debris will enter the sewage storage tank 18 through the guide arc surface. Then the water flow entering the water inlet 17 will flow in the water guide cover 14, and then flow along the guide oblique block 19 into the water guide groove 8. Taking Figures 4 and 5 as examples, this is the water guide bar 6 on both sides of the slat block 3.

[0058] In some embodiments, a bulging platform 20 is provided at the bottom of the sewage storage tank 18, a storage cylinder 21 is sleeved in the sewage storage tank 18 and abuts against the surface of the bulging platform 20, an adjustment cavity 22 is provided in the filter block 16, and a lifting bar 23 connected to the bulging platform 20 is provided in the adjustment cavity 22. The lifting bar 23 can expand its own volume after the bulging platform 20 is pressurized to guide the debris on the surface of the filter block 16 into the sewage storage tank 18.

[0059] As time goes by, some debris tends to accumulate on the filter block 16. In order to prevent the debris from clogging the filter block 16 and causing the water flow to be unable to be filtered (although multiple sash blocks 3 and multiple blocking parts 5 are arranged in a row, the function of the multiple blocking parts 5 is to divert the water flow. Once the first one fails to filter, the subsequent filtering pressure increases).

[0060] When debris enters the sewage storage tank 18, it will accumulate on the storage cylinder 21 (the storage cylinder 21 can be a mesh structure). As the amount of accumulation increases, the storage cylinder 21 will compress the bulging platform 20 (the bulging platform 20 can be a sac-like structure filled with gas). As the bulging platform 20 is compressed, the lifting bar 23 will expand its own volume, thereby increasing the size of the adjustment cavity 22. Then, the surface of the filter block 16 will bulge, thereby guiding the debris on the surface of the filter block 16 into the sewage storage tank 18.

[0061] In the present invention, the filter block 16 can be a sponge or a honeycomb structure covered with a filter mesh, such as a honeycomb structure made of silica gel.

[0062] In some embodiments, a dividing strip 24 is provided on the side surface of the isolation strip 13 away from the filter block 16, and there is a gap between the isolation strip 13 and the dividing strip 24. A baffle block 26 is provided in this gap, and the side surface of the baffle block 26 away from the slope exceeds the side surface of the dividing strip 24 away from the slope.

[0063] The function of the flow block 26 is to further block the water flow so that the water flow will not cause pressure on the subsequent filtering operation due to excessive flow rate.

[0064] In some embodiments, the two end edges of the baffle block 26 are at least flush with the two end edges of the isolation strip 13 . This arrangement is to prevent the water flow from flowing away from the two sides of the baffle block 26 .

[0065] In some embodiments, a lifting platform 25 communicating with the bulging platform 20 is provided at the bottom of the compartment, and the lifting platform 25 can lift the spoiler 26 .

[0066] When the bulging platform 20 is compressed, the bulging platform 20 will also introduce some gas into the lifting platform 25. Then the lifting platform 25 expands and lifts the baffle block 26, so that the baffle block 26 can intercept more water. That is, as more and more debris is on the filter block 16, the baffle block 26 can intercept more and more water, so that the subsequent barrier part 5 in the sash block 3 will not be too difficult to intercept.

[0067] In the present invention, the lifting platform 25, the bulging platform 20 and the lifting bar 23 can all be selected as a sac-like structure, and the three are connected by a catheter. Once the bulging platform 20 is pressurized, the lifting platform 25 and the lifting bar 23 will expand. Once the bulging platform 20 is restored, the excess gas in the lifting platform 25 and the lifting bar 23 will enter the bulging platform 20, causing the lifting platform 25 and the lifting bar 23 to be restored.

[0068] When the present invention is used, the laying net 1 is first laid from the upper part of the slope to the lower part of the slope (during the laying process, piles can be driven into the slope with reference to FIG3 , and then the laying net 1 and the slope can be fixed), and then the sash block 3 is installed on the laying net 1 (the laying net 1 and the sash block 3 can be fixed with bolts or other components during installation). When the sash block 3 is installed, the guide plug-in portion 4 is inserted into the slope along the planting hole 2.

[0069] The structure of the sash block 3, the plug-in portion 4, and the barrier portion 5 in the present invention is shown in Figures 4 and 5. Two plug-in portions 4 and two barrier portions 5 are provided, and there is a gap between the two plug-in portions 4. A water guide bar 6 is located in the gap. The following is an example with reference to Figures 4 and 5:

[0070] When the plug-in portion 4 is inserted into the slope, the blocking block 10 is facing the water flow, and the guide block 11 will be on the side of the blocking block 10. Referring to Figures 3 and 4, when the water flow contacts the blocking block 10, a part of it will flow along the guide block 11 toward the side away from the center area of ​​the limiting hole 12 (that is, enter the water guide groove 8 on the water guide bar 6 on both sides of the sash block 3), and the other part will flow away from the water guide groove 8 on the water guide bar 6 in the gap. In this way, a large amount of water can be prevented from entering the area where the planting hole 2 is located from the contact point between the bottom of the paving net 1 and the slope.

[0071] Afterwards, once the water flow is large, it cannot flow away quickly from the water guide groove 8 on the water guide bar 6, so water accumulation is formed at the high part of the slope and in contact with the paving net 1. Once the water flow accumulates more, it will spread out from the end of the slat block 3 close to the high part of the slope. The spreading water flow will then carry some debris (such as sand or leaves, etc.) into the restriction hole 12. When the water flow enters, the water flow will first be blocked by the isolation bar 13, and then enter the water inlet 17 after being filtered by the filter block 16. At the same time, when the water flow is filtered, the debris will enter the sewage storage tank 18 through the guide arc surface. The water flow entering the water inlet 17 will then flow in the water guide cover 14, and then flow along the guide oblique block 19 into the water guide groove 8. Taking Figures 4 and 5 as examples, this is the water guide bar 6 on both sides of the slat block 3.

[0072] When debris enters the sewage storage tank 18, it will accumulate on the storage cylinder 21 (the storage cylinder 21 can be a mesh structure). As the amount of accumulation increases, the storage cylinder 21 will compress the bulging platform 20 (the bulging platform 20 can be a sac-like structure filled with gas). As the bulging platform 20 is compressed, the lifting bar 23 will expand its own volume, so that the adjustment cavity 22 will increase. Then the surface of the filter block 16 will bulge, thereby guiding the debris on the surface of the filter block 16 into the sewage storage tank 18. When the bulging platform 20 is compressed, the bulging platform 20 will also introduce part of the gas into the lifting platform 25. Then the lifting platform 25 will expand and lift the baffle block 26, so that the baffle block 26 will intercept more water. That is, as the amount of debris on the filter block 16 increases, the baffle block 26 will intercept more water, so that the difficulty of interception by the barrier part 5 in the subsequent grid block 3 will not be too great.
