Description

Technical Field

[0001] The present invention relates to the technical field of high slope green slope protection, and particularly to a green anchor rod frame beam slope protection structure and method for high slopes in alpine regions. Background Art

[0002] Alpine mountainous areas usually have relatively high altitudes, cool climates, large day-night temperature differences, less rainfall, and can only adapt to the growth of relatively cold-resistant crops. Especially in some places with a high degree of weathering, unstable high slopes are extremely likely to form. The characteristics of such unstable high slopes mainly lie in their high slopes, low strength of rock and soil masses, sparse vegetation, etc. The overall stability is poor, the greening is difficult, and there are frost heaving problems in the soil in alpine cold regions, and the phenomenon of frost heaving damage is relatively frequent, making the treatment of unstable high slopes in alpine regions currently difficult. In addition, drainage problems, especially the problem of water inflow from gullies, need to be considered in alpine mountainous areas to avoid further frost heaving damage to slope protection facilities caused by water accumulation, which all increase the difficulty of slope treatment in alpine mountainous areas.

[0003] Based on this, when treating unstable high slopes in alpine mountainous areas, not only the slope stability problem needs to be considered, but also the vegetation greening problem, frost heaving damage problem, soil erosion, and slope drainage problem need to be considered. However, in the existing technology, when carrying out treatment, most slope protection treatment facilities only consider one-sided technical problems, or many problems have not been solved, which in turn leads to great limitations in the application of slope protection technologies in the existing technology, and there are many drawbacks, and the treatment cannot be carried out persistently and stably.

[0004] Based on this, how to comprehensively treat unstable high slopes in alpine mountainous areas based on the geographical characteristics of alpine mountainous areas and in combination with the above problems is an urgent problem for us to solve. Summary of the Invention

[0005] The purpose of the present invention is to provide a green anchor rod frame beam slope protection structure for high slopes in alpine regions. This structure can perform adaptive elastic displacement adjustments of different sizes at different spatial positions based on the soil frost heaving phenomenon, can well solve the soil frost heaving problem, and the overall formed connection structure can not only limit the amplitude of the adaptive elastic displacement adjustment, but also increase the overall stability of the slope protection structure. At the same time, it can also synchronously solve the problems of drainage, soil erosion, and greening, and has a significant effect on the treatment of high slopes in alpine regions.

[0006] The object of the present invention is mainly achieved through the following technical solutions: A green anchor rod frame beam slope protection structure in alpine regions consists of several filled lattice anchor rod frame components and elastic connection members. The several filled lattice anchor rod frame components are arranged at intervals in an array manner, and any two adjacent filled lattice anchor rod frame components are connected by elastic connection members to connect all the filled lattice anchor rod frame components into a whole. Among them, the filled lattice anchor rod frame component is enclosed by a border, and the inner area of the border is divided into several lattice spaces by partition boards that crisscross each other. Long anchor rod components are arranged at the corner positions of the border, the intersection positions of the partition boards, and the intersection positions of the partition boards and the border. The elastic connection member is composed of an elastic plate body, and several groups of claw components are formed at intervals along the length direction of the elastic plate body. The claw component consists of two relatively spaced claws, the claws are perpendicular to the elastic plate body, and each claw is provided with a short anchor rod component. Several through slots are also arranged on the border. When the filled lattice anchor rod frame components are arranged at intervals, the elastic connection member is arranged at the border positions of two adjacent filled lattice anchor rod frame components, and the two claws of each group of claw components are respectively clamped into the through slots on two adjacent borders.

[0007] Based on the above technical solutions, isolation boards arranged vertically and horizontally are provided in the lattice space, and the isolation boards divide the lattice space into several filling areas with unequal areas. Among the isolation boards, the horizontally arranged isolation boards are also provided with first drainage holes running through them.

[0008] Based on the above technical solutions, retaining walls are arranged at the bottom partition boards or border positions of each lattice space. The two sides of the retaining wall extend upward into the lattice space to form extension parts to partially enclose the lower area of the lattice space. Second drainage holes are arranged on the retaining wall and its two side extension parts, and the extension parts of two horizontally adjacent retaining walls are closely attached to each other and the second drainage holes of the two are communicated with each other.

[0009] Based on the above technical solutions, the retaining wall is arranged at an angle of 35° - 50° with the plane where the upper lattice space is located.

[0010] Based on the above technical solutions, the elastic plate body and the claw components are integrally cast from epoxy resin elastic concrete.

[0011] Based on the above technical solutions, the distance between two relatively spaced claws is equal to the distance between the through slots on any two adjacent filled lattice anchor rod frame components.

[0012] Based on the above technical solutions, the distance between any two adjacent filled lattice anchor rod frame components is 3 - 5 cm.

[0013] Based on the above technical solution, the jaw is inserted into the through groove and partially extends out, and the length of the jaw extending out of the through groove is 20 - 30 cm.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses a plurality of filled lattice anchor frame components arranged at intervals in an array manner, so as to carry out regional protection on the high slope area, increase the slope stability. At the same time, all the filled lattice anchor frame components are connected into a whole by elastic connection members, so that all the filled lattice anchor frame components in the high slope area exist in an integral structure, and then the stability of the integral slope protection structure is realized through the integral connection structure, thus realizing the stability and durability of the whole slope.

[0015] 2. A plurality of filled lattice anchor frame components of the present invention are arranged at intervals in an array manner. Thus, when the soil frost heaving problem occurs, a single filled lattice anchor frame component can adaptively change its displacement based on soil expansion, uneven uplift, etc., and will not break or be damaged due to the integral structure, and can better adapt to the surface changes brought by soil frost heaving. At the same time, based on the elastic connection function of the elastic connection members, it can also ensure the displacement change range of all the filled lattice anchor frame components, so as to ensure that all the filled lattice anchor frame components can change their displacements within a reasonable range, ensure the stability of all the filled lattice anchor frame components, and also, based on the elastic effect, enable all the filled lattice anchor frame components to reset adaptively after the change and form an integral slope protection structure, and ensure the stability and safety of the integral slope protection structure when adapting to soil frost heaving changes.

[0016] 3. The present invention can form several areas for filling soil and greening through the lattice space, and can be further divided into more filling areas under the action of the isolation board. Thus, it not only plays a role in greening, preventing soil erosion, but also can increase the species diversity of greening vegetation. Furthermore, reasonable vegetation can be selected for mixed planting based on the vegetation characteristics, further playing a role in soil fixation.

[0017] 4. By setting the retaining wall structure, the present invention can play a blocking role, not only effectively preventing the soil loss in each lattice space, but also playing a certain role in water blocking and water storage, so as to ensure the soil fixation effect and the vegetation irrigation problem; and through the design of the first drainage hole and the second drainage hole, it can also ensure good drainage effect for each lattice space, so as not to cause the aggravation of soil frost heaving due to excessive water storage, and thus ensure the drainage effect of the whole slope while ensuring soil fixation and irrigation.

[0018] 5. The extension parts of two adjacent retaining walls of the present invention in the horizontal direction are closely attached to each other, and the second drainage holes of the two are communicated with each other, so that the entire row of retaining walls can be connected. Furthermore, when a local retaining wall faces the water coming from above the slope, the water can be blocked and drained to other retaining walls more quickly, thereby slowing down the impact of the incoming water, increasing the drainage area, ensuring the irrigation water demand of all lattice spaces, and achieving the drainage effect more quickly.

[0019] Meanwhile, based on the above-mentioned green anchor rod frame beam slope protection structure in alpine regions, the present invention also provides a green anchor rod frame beam slope protection method for high slopes in alpine regions, which includes the following steps. S1 Slope brushing Brush the unstable high slope to form multiple free faces from top to bottom along the high slope, and reserve platforms between adjacent free faces. S2 Free face construction S21 Construction of filled lattice anchor rod frame components Drill holes and excavate the foundation trench according to the design requirements on the corresponding free face, install steel bars and formwork, and pour concrete to form the frame, partition board and retaining wall. Reserve the second drainage holes for the retaining wall; after completion, install the long anchor rod components and carry out tension cable setting and anchor sealing. Pour concrete to form the isolation board. Reserve the first drainage holes for the horizontally arranged isolation boards, and arrange and install the isolation boards in a vertical and horizontal arrangement. Pour concrete for reinforcement at the joints between the isolation boards, and at the joints between the isolation boards and the frame or partition board. Complete the construction of all filled lattice anchor rod frame components on the corresponding free face in the same way. S22 Construction of elastic connection components Pour concrete to form the elastic plate body and the claw assembly. Reserve the anchor holes for the claws of the claw assembly. Place the elastic plate body at the frame positions of two adjacent filled lattice anchor rod frame components, and ensure that the two claws of each claw assembly are respectively inserted into the through grooves on the adjacent two frames, and press the part of the claw inserted into the through groove into the slope soil body by 15 - 25 cm; after completion, install the short anchor rod components through the anchor holes and carry out tension cable setting and anchor sealing. Complete the construction of all elastic connection components on the corresponding free face in the same way. S3 Construction of intercepting and draining ditches Horizontally set conventional shallow intercepting ditches at each platform and at the slope toe position. Set conventional shallow drainage ditches on both sides of the slope, and all the conventional shallow intercepting ditches are communicated with the conventional shallow drainage ditches on both sides. S4 Backfilling and greening construction Fill the filled area with imported soil. The quality index of the imported soil is 70-80, the soil pH value is 8-8.3, the total nitrogen content is 1.0-1.4‰, the total phosphorus content is 1.96-2.06‰, the total potassium content is 2.1-2.7%, the available nitrogen content is 0.05-0.08‰, the available phosphorus content is 0.01-0.03‰, the available potassium content is 0.09-0.13‰, the organic matter content is 1.2-2%, and the total salt content is 0.65-0.76‰; After filling with imported soil, plant cold-resistant plants, and the construction is completed.

[0020] The overall implementation steps of this slope protection method are simple and convenient. The structural design of the filled lattice anchor frame component and the elastic connection component increases the overall stability of the entire slope protection structure. At the same time, it can also adapt to the problem of uneven surface uplift caused by soil frost heave, can adaptively adjust the spatial position slightly, and ensure the initial construction state. It has strong adaptability and is not easily damaged. Combined with the retaining wall and lattice space setting, it realizes the soil fixation and greening of the slope at the same time, and can also achieve the self-irrigation effect of vegetation while ensuring the retaining and drainage effects. Therefore, the slope treatment is more comprehensive and thorough, and the slope can be stably treated for a long time, which is suitable for large-scale popularization and application.

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figures 1-9 As shown, the first embodiment of the present invention discloses a green anchor frame beam slope protection structure for high slopes in high-cold areas, which is composed of a plurality of filled-in lattice anchor frame assemblies 1 and elastic connecting members 2. The plurality of filled-in lattice anchor frame assemblies 1 are arranged in an array manner, and any two adjacent filled-in lattice anchor frame assemblies 1 are connected by an elastic connecting member 2 to connect all the filled-in lattice anchor frame assemblies 1 as a whole; wherein the filled-in lattice anchor frame assemblies 1 are surrounded by a frame 3, and the internal area of ​​the frame 3 is divided into a plurality of lattice spaces 5 by criss-crossing partitions 4, and the corner positions of the frame 3, the staggered positions of the partitions 4, and the partitions 4 Long anchor rod assemblies 6 are provided at the intersection positions with the frame 3; the elastic connecting member 2 is composed of an elastic plate body 7, and the elastic plate body 7 has a plurality of groups of claw assemblies formed at intervals along the length direction, and the claw assembly is composed of two claws 8 relatively spaced apart, and the claws 8 are perpendicular to the elastic plate body 7, and each of the claws 8 is provided with a short anchor rod assembly 9; a plurality of through grooves 10 are also provided on the frame 3, and when the filled-type lattice anchor rod frame assemblies 1 are arranged at intervals, the elastic connecting member 2 is arranged at the frame 3 positions of two adjacent filled-type lattice anchor rod frame assemblies 1, and the two claws 8 of each group of claw assemblies are respectively inserted into the through grooves 10 on the two adjacent frame 3.

[0024] During application, a plurality of filled lattice anchor rod frame assemblies 1 are arranged at intervals in an array, and it is only necessary to cover the entire slope design area. The interval distance between adjacent filled lattice anchor rod frame assemblies 1 is subject to the installation of the elastic connection member 2. After the construction of each filled lattice anchor rod frame assembly 1 is completed, it is anchored and positioned by the long anchor rod assembly 6. The elastic connection member 2 is installed between adjacent filled lattice anchor rod frame assemblies 1. During installation, the elastic connection member 2 is arranged at the frame edge 3 of two adjacent filled lattice anchor rod frame assemblies 1 and fixed by the short anchor rod assembly 9. Both claws 8 of each set of claw assemblies are respectively clamped into the through grooves 10 on the adjacent two frame edges 3, and then all the filled lattice anchor rod frame assemblies 1 are connected into an integral slope protection structure through the elastic connection member 2.

[0025] Specifically, soil frost heave refers to the phenomenon that during the freezing process of soil, due to the volume expansion of water when it freezes, the soil volume increases, resulting in the ground heaving. The main causes of frost heave include the expansion of the soil mass caused by the freezing of water in the soil and the growth of ice bodies, as well as the uneven heaving of the ground surface.

[0026] Based on this, in this embodiment, the frame edges 3 of two adjacent filled lattice anchor rod frame assemblies 1 are clamped by the claws 8. When a single filled lattice anchor rod frame assembly 1 experiences uneven heaving due to soil frost heave, the claws 8 can connect the adjacent single filled lattice anchor rod frame assemblies 1, thereby reducing the excessive spatial displacement change amplitude of a single filled lattice anchor rod frame assembly 1. At the same time, it can also limit the spatial displacement change amount of each filled lattice anchor rod frame assembly 1 through the mutual connection effect, and provide mutual forces to maximize the offset of the surface action. During this process, based on the elastic effect of the elastic plate body 7, the overall elastic connection member 2 can adapt to the change and perform a certain elastic extension, and can also pull adjacent filled lattice anchor rod frame assemblies 1 towards each other based on its elastic effect, ensuring that all filled lattice anchor rod frame assemblies 1 will not loosen, slip, etc. When the ground surface returns to its original state, it can also pull adjacent filled lattice anchor rod frame assemblies 1 towards each other based on its elastic effect to maximize the restoration of the design position, thereby facilitating the stability and durability of the slope protection structure.

[0027] Furthermore, the slope protection structure of this embodiment utilizes several split filled lattice anchor frame assemblies 1 laid on the slope, which can undergo independent spatial displacement changes with each other, and can undergo spatial displacement changes of different amplitudes and sizes with each other. A single filled lattice anchor frame assembly 1 is not easy to break or damage. At the same time, based on the connecting action of the elastic connecting member 2, all the filled lattice anchor frame assemblies 1 form an integral structure, the overall stability of the slope protection structure is increased, and it can also adapt to the spatial displacement changes of a single filled lattice anchor frame assembly 1, and thus can adapt to the surface uplift and unevenness caused by soil frost heave in high-altitude cold areas. The elastic connecting member 2 is elastic, and can be based on the displacement changes of a single filled lattice anchor frame assembly 1 without being easily damaged. It can also restrain the single filled lattice anchor frame assembly 1 under the elastic action, reduce the displacement change amplitude, and quickly retract the single filled lattice anchor frame assembly 1 after the change to reset it, thereby ensuring the stability of the facility. At the same time, each filled lattice anchor frame assembly 1 of the present embodiment is formed with a plurality of lattice spaces 5, and vegetation can be planted by utilizing the lattice spaces 5 to solve the problem of slope greening.

[0028] In order to further adapt to the geographical characteristics of high slopes in high-cold mountainous areas, the lattice space 5 of this embodiment is provided with vertically and horizontally arranged isolation plates 11, which divide the lattice space 5 into several filling areas of different areas; among the isolation plates 11, the horizontally arranged isolation plates 11 are also penetrated with several first drainage holes 12. The lattice space 5 is divided into several filling areas of different areas. After the filling is completed, vegetation of different types and characteristics can be planted in different filling areas based on needs, which can not only enrich the vegetation types, but also be mixed according to the characteristics of different vegetation to ensure the vegetation planting effect and better achieve the soil consolidation effect; at the same time, in order to avoid the problem of soil frost heave caused by water accumulation, the first drainage hole 12 is also penetrated in each horizontally arranged isolation plate 11 in this embodiment, so that the first drainage hole 12 can drain the excess water in the lattice space and evenly distribute the soil moisture content in each filling area in the lattice space.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a retaining wall 13 is provided at the bottom partition 4 or frame 3 of each of the lattice spaces 5, and both sides of the retaining wall 13 extend toward the upper lattice space 5 to form an extension portion 14 to partially surround the lower area of ​​the lattice space 5; second drainage holes 15 are provided on the retaining wall 13 and the extension portions 14 on both sides thereof, and the extension portions 14 of two laterally adjacent retaining walls 13 are tightly fitted to each other and the second drainage holes 15 of the two are connected to each other.

[0030] In specific implementation, due to the high slope gradient, serious weathering phenomenon, and the possible problem of water inflow from gullies, the soil filled in the lattice space 5 is extremely easy to erode. Coupled with the low average annual rainfall and the difficulty of vegetation survival, when protecting high slopes in alpine regions at present, how to conserve soil and ensure the survival of vegetation is an extremely important issue.

[0031] Based on this, in this embodiment, retaining walls 13 are correspondingly arranged below each lattice space 5, and the retaining walls 13 and their extended parts 14 are used to locally enclose the lower region of the lattice space 5. Furthermore, based on the design of the retaining walls, soil erosion in each lattice space can be well blocked. At the same time, when it rains or there is water inflow from gullies, it can also play a certain role in blocking and storing water, ensuring the water use of the vegetation in each lattice space, and effectively solving the problems of vegetation irrigation and soil consolidation.

[0032] Specifically, the extended part 14 is a plate structure formed by bending the two sides of the retaining wall 13 towards the two end parts of the lattice space. It can not only form a semi-closed space structure with the retaining wall 13, but also better avoid the design position of the long bolt assembly 6.

[0033] At the same time, considering that excessive water storage will exacerbate the problem of soil frost heave, in this embodiment, a second drain hole 15 is further provided. Thus, alone or in combination with the first drain hole 12, it can ensure good drainage effect for each lattice space, preventing excessive water storage from exacerbating soil frost heave. Furthermore, while ensuring soil consolidation and irrigation, the overall drainage effect of the slope is also guaranteed.

[0034] Furthermore, the extended parts 14 of two adjacent retaining walls 13 in the horizontal direction are closely attached to each other and the second drain holes 15 of the two are communicated with each other, so that the entire row of retaining walls 13 can be connected. Then, when a local retaining wall 13 faces a large flow of water from above the slope (such as water inflow from a gully), the water can be blocked and can be drained more quickly to other retaining walls 13 and into the lower lattice space 5, thereby slowing down the impact of the incoming water and increasing the drainage area, ensuring the irrigation water demand of all lattice spaces 5 and achieving a faster drainage effect.

[0035] In specific application, multiple second drain holes 15 can be provided on the retaining wall 13, and they can be arranged at the bottom, middle or top of the retaining wall 13. In this embodiment, considering the problem of vegetation irrigation, they are arranged at the top of the retaining wall 13 to facilitate a certain water storage effect of the retaining wall 13.

[0036] As a specific implementation, the retaining wall 13 is set at 35° to 50° with the plane where the upper lattice space 5 is located. During implementation, the filling lattice anchor frame assembly 1 where the lattice space 5 is located is basically constructed on the slope surface in a downward tilted manner. Based on different design requirements, the general tilt angle is 30° to 55°. Therefore, after construction, the angle between the overall retaining wall 13 and the horizontal plane is about 80° to 90°, which is basically maintained vertically with the horizontal plane, so that it can better achieve the function of blocking soil or water.

[0037] like Figure 6 , Figure 7 and Figure 8 As shown, the elastic plate body 7 and the claw assembly are cast in one piece by epoxy resin elastic concrete. Epoxy resin elastic concrete is a concrete material that can undergo a certain degree of elastic deformation when subjected to load. It is mainly composed of cement sand, aggregate and other materials mixed in a scientific proportion, and special additives may be added to enhance its performance. It has good ductility, elasticity and fracture resistance. Furthermore, when the filled lattice anchor frame assembly 1 changes in spatial displacement due to soil frost heave, the elastic plate body 7 and the claw assembly can adapt to the change, and at the same time give a certain pulling force for restraint, and will not be damaged itself, which is conducive to long-term use.

[0038] As a specific implementation, the spacing between the two relatively spaced claws 8 is equal to the spacing between any two adjacent through slots 10 on the filled lattice anchor frame assembly 1. With such a design, after the construction of the filled lattice anchor frame assembly 1 is completed, the claws 8 can be accurately inserted into the through slots 10 to ensure the installation of each elastic connecting member.

[0039] As a further implementation, the spacing between any two adjacent infilled lattice anchor frame assemblies 1 is 3 to 5 cm. In application, in order to avoid excessive spacing between adjacent infilled lattice anchor frame assemblies 1, exposing more slope surfaces, and also to give the infilled lattice anchor frame assemblies 1 a certain displacement space margin, in this embodiment, when the spacing is set to 3 to 5 cm, not only can the above-mentioned problem be solved, but also during construction, different infilled lattice anchor frame assemblies 1 can be better constructed separately based on the slope amplitude change, thereby increasing construction convenience.

[0040] As a specific implementation manner, the jaw 8 is snapped into the through groove 10 and partially protrudes, and the length of the jaw 8 protruding from the through groove 10 is 20-30 cm. During application, the part of the jaw 8 protruding from the through groove 10 can be pressed into the soil of the lower slope to increase the stability of the jaw 8 and prevent it from detaching from the through groove 10. At the same time, since part of the jaw 8 is in the soil, it can also provide greater support force in combination with the soil, thereby preventing the filling type lattice anchor rod frame assembly 1 from being damaged or displaced under the action of tension, and overall improving the positioning effect of the elastic connection member 2.

[0041] The above is the specific content of the green anchor rod frame beam slope protection structure for high slopes in alpine regions. For better understanding and implementation, as Figure 10 、 Figure 11 shown, the second embodiment of the present invention also provides a green anchor rod frame beam slope protection method for high slopes in alpine regions based on it, including the following steps: S1 Slope brushing Brush the unstable high slope to form multiple stepped free faces a from top to bottom along the high slope, and reserve a platform b between adjacent free faces a; In this step, slope brushing includes construction steps such as cleaning floating stones, mechanical slope brushing, manual slope brushing, and filling and tamping in accordance with the construction sequence, which can be achieved based on the existing technology, and will not be specifically described in this embodiment.

[0043] In the specific implementation process, after the measurement and layout, and the construction of the support platform are completed, drill holes and excavate the foundation trench according to the design requirements of the filling type lattice anchor rod frame assembly 1, and install formwork to pour the frame 3, partition 4 and retaining wall 13. And in order to increase the overall structural stability, install steel bars in the formwork as the internal skeleton structure of the frame 3, partition 4 and retaining wall 13.
