Description

Technical Field

[0001] The invention relates to the technical field of slope protection, and in particular to a slope protection structure and method for reducing soil erosion on a slope. Background Art

[0002] As an important water resource system and component of the ecosystem, rivers are of great significance to human life and natural ecology. However, due to the influence of human activities and natural factors, many rivers have long faced problems such as riverbank collapse, soil erosion and water quality deterioration, which have brought many challenges to the ecological environment and human society. Therefore, it is imperative to carry out river management projects to restore the stability and ecological functions of rivers.

[0003] As one of the important design and application methods in river management projects, ecological slope protection has attracted widespread attention for its advantages of effectively protecting river banks, reducing soil erosion, improving water quality, and increasing ecological functions. At present, the commonly used ecological slope protection methods include vegetation blanket slope protection, artificial grass slope protection, vegetation concrete ecological slope protection, etc. Taking vegetation blanket slope protection as an example, the vegetation blanket is a three-layer integral bonding of growth substrates such as seeds and fertilizers with fiber nets and ecological cloth in the production factory. After being transported to the construction site for paving, it is fixed to the surface of the soil or weathered rock slope with special anchors. The purpose of preventing soil erosion is achieved through fiber nets and ecological cloth in the early stage. After the plants grow, the vegetation and root system play a role in deep prevention of scouring and inhibition of soil erosion. It is a perfect combination of preventing water scouring, inhibiting soil erosion and environmental greening.

[0004] The construction process is construction layout - slope trimming - vegetation blanket laying - anchoring and fixing - soil covering - watering and maintenance. In the existing construction process, after the soil covering process is completed, since the surface is plain soil, if it rains or when watering, the surface soil is easily washed away, causing soil erosion, reducing the windproof, heat preservation and moisture retention functions of the soil covering, which may affect the germination of grass seeds and make it difficult to restore the slope vegetation.

[0005] In summary, there are still some problems in the existing vegetation blanket slope protection construction technology. Combined with the current hot spot of recycling waste rubber resources, how to organically combine the two, seek benefits and avoid harm, enhance the protection effect of the slope, and restore the stability and ecological function of the river channel needs further research. Summary of the invention

[0020] On the other hand, the present technical solution proposes a slope protection method for reducing soil erosion on the slope, comprising the following steps:

[0021] S1: Slope leveling: repair and level the slope surface before construction;

[0022] S2: Grooving: Open a groove at the top and foot of the slope;

[0035] ③ Binding and fixing: Use nylon tie to pass through the corresponding overflow hole of the reinforcement and the through hole of the tail cap and then bind and fix them together.

[0036] The above technical solution has the following advantages or beneficial effects:

[0037] 1. The present invention introduces a flexible rubber strip into the existing vegetation blanket slope protection construction. On the one hand, the flexible rubber strip is made of waste rubber material to realize the utilization of waste resources; on the other hand, the flexible rubber strip is buried in the soil in a reinforced manner, and the high friction and high elasticity of the flexible rubber strip are utilized to form a reinforced soil structure, which increases the friction between the flexible rubber strip and the soil, plays a role in consolidating the soil, and improves the stability of the slope.

[0038] 2. The flexible rubber strip is an "8"-shaped structure, which forms multiple honeycomb cells after being linked. The honeycomb cells greatly increase the bite effect between the rubber strip and the soil, and the macroscopic form of this bite force is the interface cohesion. Therefore, the cohesion of the "8"-shaped flexible rubber strip is very significant, and it has a good reinforcement effect. In addition, the "8"-shaped flexible rubber strip is a closed-loop structure. The bite force between the soil and the flexible rubber strip includes the resistance of the horizontal part of the flexible rubber strip to the soil and the restraint of the vertical part to the soil. The flexible rubber strips connected vertically and horizontally to form a closed loop have a significant restraint effect on the soil. The reinforced composite structure formed has high anti-slip ability and can effectively prevent soil erosion.

[0039] 3. The reinforced soil formed by the flexible rubber strip and the soil improves the shear strength of the soil, and can be used to treat the slopes of soft soil layers to increase the bearing capacity or as a stress buffer layer to reduce the stress and deformation of the lower structure.

[0040] 4. Laying out ecological sticks along the contour lines can shorten the slope length, disperse slope runoff, and intercept runoff sediment, thereby stabilizing the slope soil and seeds. It plays an important role in reducing slope flow and flow velocity, and can effectively reduce soil erosion. At the same time, the ecological sticks are low in cost, simple in process, and have better ecological effects.

[0041] 5. The eco-rod is fixed with a cable-type fixing device and is equipped with a supporting member. Relying on the "pulling force" of the fixing member and the "supporting force" of the supporting member, double fixation is achieved, with good fixing effect, increased adhesion, stable force, and prevention of the eco-rod from falling off due to later rain erosion; in addition, the supporting member is coordinated with the second anchor and the reinforcement member, with a simple structure, convenient construction, interlocking integration, and stable support.

[0056] In order to make the objects, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, rather than all the embodiments.

[0057] Embodiment 1:

[0058] like Figure 1 - Fig.12 As shown, this embodiment proposes a slope protection structure for reducing soil erosion on a slope 1, which mainly includes a vegetation blanket 4, an ecological rod 6, a reinforcement net 8 and other parts, which are described in detail below:

[0059] The slope protection structure includes a vegetation blanket 4 laid on the slope surface, and the two ends of the vegetation blanket 4 are respectively fixed to the top 2 and the foot 3 of the slope; in this embodiment, the two ends of the vegetation blanket 4 can be fixed in a conventional manner, that is, by pouring concrete after grooving to form a concrete top 5 for fixing.

[0060] The vegetation blanket 4 mentioned in this embodiment, also known as ecological blanket, environmentally friendly vegetation blanket 4, plant fiber blanket, and anti-scouring vegetation blanket 4, is a natural high-strength slope protection and greening material. It is laid on the slope 1 and is green and beautiful. It is a kind of anti-scouring slope protection and greening material made of grass seeds, natural plant fibers, geotextiles, etc. through advanced equipment. It is an ideal slope protection and greening material for river ecological management, reservoir dam protection, etc.

[0061] The slope protection structure also includes a number of interception bodies arranged at intervals along the contour line direction on the surface of the vegetation blanket 4. The interception bodies are arranged at intervals along the slope surface direction. The interception bodies divide the surface of the vegetation blanket 4 into a number of unit areas, and change the original flat slope surface of the vegetation blanket 4 into an up and down undulating structure to reduce slope scour; the interception body is composed of a number of ecological rods 6 arranged, and the ecological rods 6 are fixed on the slope surface; the purpose of introducing the ecological rods 6 in this embodiment is: the ecological rods 6 arranged along the contour line can shorten the slope length, disperse the slope runoff, and have the function of intercepting runoff sediment, thereby stabilizing the soil and seeds of the slope 1, playing an important role in reducing the slope flow and reducing the flow rate, and can effectively reduce soil and water loss; at the same time, the ecological rods 6 have low cost, simple process, and better ecological effect. The ecological rods 6 can better reduce soil and water loss, provide a better living environment for plants, and have a simple structure and convenient construction.

[0062] On the other hand, changing the originally flat and smooth slope surface into an up-and-down undulating structure can reduce the scouring speed of the slope surface, play a blocking and speed-reducing role, and thus reduce soil erosion.

[0063] It should be noted that the eco-stick 6 is a long or cylindrical eco-bag. Usually, an eco-bag with a length of more than 1 meter is called an eco-stick 6. The eco-stick 6 is also called a vegetation stick, an ecological long bag, a slope protection long bag, a slope 1 greening bag, a vegetation bag, etc., and because the eco-stick 6 is made of geotextile, it is also called a geotextile bag. The eco-stick 6 is made of a high-strength non-woven geotechnical material formed by cross-laying and needle-punching of polypropylene artificial fibers. It has the characteristics of strong corrosion resistance, UV resistance, aging resistance, non-toxicity, non-combustibility, good stability, and no extension of cracks. The length of the eco-stick 6 can be customized as needed. The eco-stick 6 contains plant seeds, soil, matrix, etc. mixed in a certain ratio, which are stacked and fixed on the slope 1, and vegetation can grow by watering.

[0064] In the slope protection structure, a plurality of reinforcing members 81 are provided on the surface of the vegetation blanket 4 in the unit area, and the reinforcing members 81 are fixedly connected to the slope surface; the reinforcing members 81 are formed by flexible rubber strips made of waste rubber; the middle part of the reinforcing members 81 is tied and gathered to form an "8"-shaped structure as a whole; adjacent reinforcing members 81 are tied and fixed to form a reinforcing net 8; after a plurality of reinforcing members 81 are chained, a plurality of honeycomb cells 82 are constructed.

[0065] It should be noted that, in some embodiments, the reinforcing member 81 may be a waste annular triangular belt, which is connected in the middle to form an "8"-shaped structure. In some embodiments, the reinforcing member 81 may also be made of waste tires, which are cut into a plurality of annular tire strips, which are connected in the middle to form an "8"-shaped structure.

[0066] In the slope protection structure, the surface of the vegetation blanket 4 in the unit area is covered with topsoil 9, and the reinforcement members 81 are buried in the topsoil 9 to form a reinforced soil structure.

[0067] In the above, the present invention introduces a flexible rubber strip into the existing vegetation blanket 4 slope protection construction, and its purpose is: on the one hand, the flexible rubber strip is made of waste rubber material to realize the utilization of waste resources; on the other hand, the flexible rubber strip is embedded in the soil in a reinforced manner, and the high friction and high elasticity of the flexible rubber strip are used to form a reinforced soil structure, which increases the friction between the flexible rubber strip and the soil, plays a role in consolidating the soil, and improves the stability of the slope 1. On the other hand, the flexible rubber strip has high elasticity and has its own deformation function, and can be adaptively deformed according to the soil; the reinforced soil formed by the flexible rubber strip and the soil improves the shear strength of the soil, and can handle the soft soil layer slope 1 to improve the bearing capacity or serve as a stress buffer layer to reduce the stress and deformation of the lower structure.

[0068] In this solution, the flexible rubber strip is an "8"-shaped structure, which can form multiple honeycomb cells 82 after being linked. The honeycomb cells 82 greatly increase the bite effect between the rubber strip and the soil, and the macroscopic form of this bite force is the interface cohesion. Therefore, the cohesion of the "8"-shaped flexible rubber strip is very significant, and has a good reinforcement effect. In addition, the "8"-shaped flexible rubber strip is a closed-loop structure. The bite force between the soil and the flexible rubber strip includes the resistance of the horizontal part of the flexible rubber strip to the soil and the restraint of the vertical part to the soil. The flexible rubber strips connected vertically and horizontally to form a closed loop have a significant restraint effect on the soil. The reinforced composite structure formed has high anti-slip ability and can effectively prevent soil erosion.

[0069] In addition, in the present embodiment, the setting of the eco-rod 6 can not only shorten the slope length and disperse the slope runoff, but also has the function of intercepting runoff sediment and stabilizing the soil of the slope 1; it can also intercept the topsoil 9. The eco-rod 6 is permeable to water but not to soil. It is set on the slope surface and can intercept part of the soil. The soil trapped in the slope runoff water can be well intercepted by the eco-rod 6, thereby reducing soil and water loss.

[0070] The vegetation in the ecological rod 6 and the vegetation blanket 4 can form a thriving root system, which is combined with the slope body into a homogeneous whole, so that the artificial slope 1 and the original natural slope 1 will not separate or collapse. Moreover, as time goes by, the increasingly strong vegetation root system makes the slope 1 structure more stable and firm, forming a natural, living and permanent ecological project.

[0071] In this embodiment, the eco-rod 6 is fixed to the slope surface by a fixing member 7, and the fixing member 7 includes an "8"-shaped lock buckle 72 made of waste rubber, which is pressed on the top of the eco-rod 6, and the two ends of the lock buckle 72 are respectively fixed to the slope surface by first anchors 71, forming an inclined cable style. In this embodiment, the lock buckle 72 can be made of waste V-belts or tire strips formed by cutting waste tires.

[0072] In some embodiments, if the original slope 1 has poor soil quality and is not conducive to the growth of vegetation, the following operation can be adopted:

[0073] The space between the vegetation blanket 4 and the slope is filled with foreign soil, which is organic planting soil, and a number of reinforcing members 81 are buried in the foreign soil, which are fixed to the slope by second anchors 11. The reinforcing members 81 are also arranged in the organic planting soil, which can play a good role in soil consolidation.

[0074] In this embodiment, the first anchor 71 and the second anchor 11 are both U-shaped structures.

[0075] In some embodiments, considering that the reinforcing member 81 has poor water permeability and each area is relatively separated, which is not conducive to water infiltration, a number of overflow holes 801 are opened along the circumference of the reinforcing member 81; the overflow holes 801 can connect each honeycomb cell 82 to facilitate water infiltration; in addition, the roots of thriving vegetation can also enter the overflow holes 801, connecting each honeycomb cell 82 to form a well-connected root network, thereby reinforcing the entire slope and helping to reduce soil erosion.

[0076] In this embodiment, the middle part of the reinforcement member 81 is tied and fixed after being passed through the corresponding overflow hole 801 through the nylon tie 10. The overflow hole 801 is not only used for water overflow and root penetration, but also can be used as an installation point for tying the reinforcement member 81. When in use, the nylon tie 10 is passed through the overflow hole 801 to achieve the middle part of the reinforcement member 81 to be tied, forming a tied portion 811, which is convenient for installation.

[0077] On the other hand, this embodiment also proposes a slope protection method for reducing soil erosion on a slope, comprising the following steps:

[0078] S1: Slope leveling: The slope surface should be repaired and leveled before construction; 3 to 4 days before the slope leveling construction, the slope 1 should be sprayed with herbicides, and herbicides that do not seal the ground should be selected; dead weeds, grass roots, construction waste, large stones and other things that are not conducive to the growth of slope protection grass seeds on the slope 1 should be removed. After these are removed, the slope 1 should be leveled with an iron rake, which is conducive to better attachment of the vegetation blanket 4 to the slope 1.

[0079] Note: There should not be a large amount of gravel, tree roots, stumps or other garbage with a particle size larger than 50mm on the slope. No protruding or sunken parts are allowed, and they should be compacted. All water accumulation within the paving work range should be removed. 2) If there is no natural topsoil on the slope (foundation) or the thickness of the topsoil is less than the thickness specified in the drawings, the topsoil should be added until it meets the requirements of the drawings.

[0080] S2: Grooving: dig a groove at the top 2 and the foot 3 of the slope, with a depth and width of no less than 30cm×30cm.

[0081] Note: The cross-sectional form and depth of the trench must meet the requirements of the construction drawings. If there is a large amount of water in the trench, relevant drainage measures must be taken to prevent the trench wall from collapsing.

[0082] S3: Laying: Measure the length of the slope, cut the length of the vegetation blanket 4 not less than the length of the slope plus the depth of the grooves at both ends, move the vegetation blanket 4 to the laying position, and adjust the laying position; the two ends of the vegetation blanket 4 are fixed by pouring concrete into the grooves to form a concrete top 5. Of course, the slope foot 3 can also be fixed without grooving, for example, it can be fixed by gabion stone cages.

[0083] S4: Anchoring of the vegetation blanket 4: fixing the vegetation blanket 4 on the slope surface with steel nails;

[0084] Notes in S3-S4: 1) The laying direction of the vegetation blanket 4 should be determined according to the force direction of the material, the hydrological conditions of the river channel and other factors, and should meet the requirements of the construction drawings. 2) When laying the vegetation blanket 4, pay attention to distinguishing the front and back sides, and maintain appropriate tightness during the laying process to adapt to the deformation of the foundation. 3) Try to avoid construction in hot weather to avoid excessive heat absorption. 4) During the laying process, workers must not wear shoes with spikes. Concrete slope protection blocks must not be unloaded directly on the vegetation blanket 4, and pointed steel bars must not be used as prying tools. It is strictly forbidden to hit stones on the vegetation blanket 4 and any construction work that may damage the vegetation blanket 4. 5) The overlap method and overlap length of the vegetation blanket 4 should meet the requirements of the construction drawings and relevant specifications. The overlap direction is in the direction of the water flow. If the vegetation blanket 4 is found to be damaged, it should be repaired or replaced immediately. 6) The vegetation blanket 4 damaged during the construction process should be repaired in time according to the supervisor's instructions. The damaged vegetation blanket 4 should be replaced with a qualified vegetation blanket 4 to cover the damaged part, and relevant overlapping measures should be taken, and steel nails should be used to strengthen the anchoring.

[0085] If necessary, the road surface can be hardened at the top 2 and the foot 3 of the slope.

[0086] S5: Interceptor construction:

[0087] A number of spaced ecological rods 6 are arranged along the slope direction, and the ecological rods 6 are arranged in rows, and multiple ecological rods 6 in each row form an interception body; the ecological rods 6 are fixed to the surface of the vegetation blanket 4 through the fixing parts 7. During construction, the lock buckle 72 is pressed on the surface of the ecological rod 6, and the two ends of the lock buckle 72 are fixed to the slope through the first anchor nail 71 to realize the hanging of the ecological rod 6; the interception body divides the blanket surface of the vegetation blanket 4 into a number of unit areas, and changes the original flat slope of the vegetation blanket 4 into an up and down undulating structure.

[0088] S6: Install reinforcement 81:

[0089] The reinforcing member 81 is made of waste rubber to form an "8"-shaped structure; according to the size of the slope, multiple reinforcing members 81 are linked together to form a reinforcing net 8, and then the reinforcing net 8 is laid in the unit area and fixed with multiple second anchors 11; after the reinforcing members 81 are laid, a number of honeycomb cells 82 are formed on the slope; the linkage between the reinforcing members 81 can be fixed by tying with nylon ties 10, and the service life is long.

[0090] S7: Covering:

[0091] The surface of the vegetation blanket 4 in each unit area is covered with topsoil 9, and the reinforcement members 81 are buried in the topsoil 9 to form a reinforced composite structure;

[0092] Notes: 1) The quality and thickness of the covering soil shall be strictly in accordance with the design requirements, and the particles of the covering soil shall not be too large. 2) During the covering process, if there are landscape requirements and other factors that require the placement of landscape stones or other landscape materials on the vegetation blanket 4, effective measures should be taken to prevent the landscape stones or other landscape materials from rolling on the slope surface, and to prevent mechanical handling from damaging the laid vegetation blanket 4. 3) If the soil on the original slope contains construction waste and other harmful components, foreign soil or technical measures to improve the soil should be used to meet the basic conditions for plant growth.

[0093] In this embodiment, the thickness of the soil covering can be 1-3 cm, which is determined according to the actual situation. In order to conveniently determine the soil covering thickness, the height of the flexible rubber strip can be used as a reference point. For example, if the designed soil covering thickness is 2 cm, then when making the flexible rubber strip, the flexible rubber strip can be directly cut to a height of 2 cm. In this way, when covering the soil, the flexible rubber strip can be used as a reference point for the soil covering thickness, which facilitates the realization of uniform soil covering.

[0094] S8: Maintenance: Watering and maintenance should be carried out scientifically and reasonably to ensure the growth needs of plants. The vegetation blanket 4 needs to be watered once in the morning and evening within 15 days after laying, once a day during 16 to 30 days, and twice a week during 31 to 60 days. The amount of water each time should be enough to soak the 10cm soil layer (except for natural rainfall) to ensure the growth needs of plants.

[0095] Embodiment 2:

[0096] Continue to refer to the attached Figure 1 - Fig.12 In this embodiment, considering that the fixation of the eco-rod 6 by the fixing member 7 alone may be unstable, especially when it rains heavily, the water in front of the eco-rod 6 will have a greater effect on the eco-rod 6, which may cause the eco-rod 6 to fall off. In order to avoid this problem, the following measures are also implemented:

[0097] The entire slope protection structure also includes a supporting member for supporting the ecological rod 6, the supporting member includes a dowel 12, the bottom end of the dowel 12 is fixedly inserted on the slope surface, and the structure of the dowel 12 is U-shaped; it also includes a top rod 13 for supporting the top dowel 12, one end of the top rod 13 is connected to a U-shaped clamping head 131, and the clamping head 131 can be clamped and connected with the dowel 12, that is, the clamping head 131 can be clamped at the top position of the dowel 12 to form a top support; at least the middle area of ​​the reinforcement member 81 is fixed to the slope surface by the second anchor 11 On the top; the other end of the top rod 13 is fixedly connected with a "Y"-shaped tail cap 132, and a through hole 1321 is opened on the tail cap 132, and the tail cap 132 can be clamped with the top of the second anchor 11, that is, the tail cap 132 can be clamped with the top of the second anchor 11; and the overflow hole 801 corresponding to the through hole 1321 and the reinforcing member 81 is penetrated and tied with a nylon tie 10, and the nylon tie 10 binds and fixes the second anchor 11, the reinforcing member 81 and the top rod 13 together to form a bottom support. The second anchor 11 is inserted and fixed in the gathering portion 811. The upper and lower ends of the flexible rubber strip are thicker than the gathering portion 811. The second anchor 11 is fixed in the gathering portion 811 and is not easy to slip, and can form a strong supporting point. It is very appropriate to use the second anchor 11 as the base point for installing the top rod 13. Moreover, the length of the gathering portion 811 can be changed according to actual conditions. The required length can be determined by tying a suitable nylon tie 10. In this way, the position of the second anchor 11 can be installed according to actual conditions, thereby providing convenient conditions for facilitating the installation of the top rod 13 and having few limitations on use.

[0098] This embodiment proposes a slope protection method for reducing soil erosion on a slope. Based on the method in the first embodiment, the method further includes the following steps: S6 also includes installing a supporting member. The specific method is as follows:

[0099] ① Install the dowel 12: insert the dowel 12 under the eco-rod 6 for support;

[0100] ② Installing the push rod 13: One end of the push rod 13 is clamped on the top of the dowel 12 through the clamping head 131, and the other end of the push rod 13 is clamped on the top of the second anchor 11 through the tail cap 132;

[0101] ③ Binding and fixing: Use a nylon tie 10 to pass through the overflow hole 801 corresponding to the reinforcement member 81 and the through hole 1321 of the tail cap 132 and then bind and fix them into one.

[0102] In this embodiment, the ecological rod 6 is fixed by a cable-type fixing member 7 and is provided with a supporting member. Relying on the "pulling force" of the fixing member 7 and the "supporting force" of the supporting member, double fixation is achieved, with good fixing effect, increased adhesion, stable force, and prevention of the ecological rod 6 from falling off due to later erosion by rainwater; in addition, the supporting member is coordinated with the second anchor member and the reinforcing member 81, with a simple structure, convenient construction, interlocking integration, and stable support.

[0103] In summary: after the vegetation blanket 4 is laid on the slope 1, the grass seeds germinate, and the strong grass roots of the plants are closely integrated with the geotextile and the slope 1 to control hydraulic erosion and soil loss, and achieve the purpose of anti-scouring and flow resistance; at the same time, the growth of plants can achieve better landscape effects and ecological restoration functions, and return rivers and lakeshores to nature; before the turf grows, it can protect the land surface from erosion by wind and rain, and stabilize the grass seeds in the early stage of sowing. After the plants grow up, the composite protective layer can withstand the scouring of high water levels and high flow rates of rainwater (river water); it can replace concrete, asphalt, riprap, stone masonry and other slope protection materials, and can be widely used for slope protection of rivers, dams, roads, railways, hillsides, municipal gardens, etc.

[0104] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
