Description

TECHNICAL FIELD

[0001] The utility model relates to high and steep slope engineering afforestation technical field, specifically, relate to a kind of solidification and re-greening structure of acidification high and steep slope. BACKGROUND

[0002] In the exploitation process of non-ferrous metal mine, especially when using open-pit mining method, a large number of high and steep slopes are often generated. The PH value of high and steep slope is less than 4.5, and the slope is between 45° and 75°. These slopes not only have complex geological conditions, but also are affected by acid mine water seepage and heavy metal pollution, forming a special environment of acidification high and steep slope. In this environment, the soil pH value is extremely low, the heavy metal content is high, and the natural vegetation is difficult to grow, which leads to the decrease of slope stability, the aggravation of water and soil loss, and even the occurrence of natural disasters such as landslide and collapse, posing a serious threat to the safety of mine operation, surrounding ecological environment and personnel life and property safety.

[0003] At present, for the repair of acidification high and steep slope in non-ferrous metal mine, various methods have been tried inside and outside the industry, including but not limited to spray seeding afforestation, plant bag afforestation, guest soil covering afforestation and engineering reinforcement afforestation. However, these traditional methods have encountered a series of problems in practical application, as follows:

[0004] Spray seeding afforestation: the mixture of grass seeds, soil, fertilizer and water is sprayed onto the slope by a spray seeding machine to realize afforestation. However, on the extremely acid and bare rock slope, the effect is not good due to the lack of suitable soil and the vulnerability to water damage, the vegetation coverage is low, and it is difficult to maintain stability, with high subsequent maintenance cost.

[0005] Plant bag afforestation: the afforestation materials and seeds are put into bags and fixed on the slope for afforestation. However, this method has extremely high implementation cost on high and steep slope, and the plant bags are easy to slide down due to the particularity of the slope, so the afforestation effect is unstable.

[0006] Guest soil covering afforestation: foreign soil is covered on the slope to improve the soil conditions and plant vegetation. This method is difficult to implement in areas with serious heavy metal pollution because the cost of obtaining and transporting guest soil is high, and it is difficult to maintain soil stability on high and steep slope.

[0007] Engineering reinforcement afforestation: the slope is reinforced by engineering means such as anchor rod, hanging net and concrete, and then afforestation is carried out. Although it can effectively improve the stability of the slope, the engineering cost is high, the environment is damaged, and the afforestation layer is often thin, the vegetation has poor stress resistance and is easy to degrade.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] During the mining process of non-ferrous metal mines, especially when using open-pit mining methods, a large number of steep slopes are often generated. These steep slopes have a pH value of less than 4.5 and a slope angle between 45° and 75°. These slopes not only have complex geological conditions but are also affected by acidic mine water seepage and heavy metal pollution, forming a special environment of acidified steep slopes. In this environment, due to the extremely low soil pH value and high heavy metal content, natural vegetation cannot grow, leading to reduced slope stability, accelerated soil erosion, and even natural disasters such as landslides and collapses. This poses a serious threat to the safe operation of the mine, the surrounding ecological environment, and the safety of people and property.

[0044] Currently, various methods have been tried both within and outside the industry for the restoration of acid-affected steep slopes in non-ferrous metal mines, including but not limited to hydroseeding, vegetation bag planting, topsoil covering, and engineering reinforcement. However, these traditional methods have encountered a series of problems in practical applications, as follows:

[0045] Hydroseeding: A mixture of grass seeds, soil, fertilizer, and water is sprayed onto slopes using a hydroseeding machine to achieve greening. However, on highly acidic and bare rocky slopes, the effect is poor due to the lack of suitable soil and susceptibility to water damage. The vegetation coverage is low, difficult to maintain, and has high subsequent maintenance costs.

[0046] Vegetation bag greening: Greening materials and seeds are placed in bags and fixed to the slope for greening. However, this method is extremely costly to implement on steep slopes, and due to the special characteristics of the slope, the vegetation bags are prone to slipping, resulting in unstable greening effects.

[0047] Guest soil covering greening: cover the outside soil on the slope to improve the soil condition and plant vegetation. This method is difficult to implement in areas with serious heavy metal pollution because the cost of obtaining and transporting the guest soil is high, and it is difficult to maintain soil stability on high and steep slopes.

[0048] Engineering reinforcement greening: reinforce the slope by means of anchor rod, hanging net, concrete and other engineering means, and then green. Although it can effectively improve the stability of the slope, the engineering cost is high, the environment is damaged, and the green layer is often thin, the vegetation resistance is poor, and it is easy to degrade.

[0049] The main purpose of the utility model is to provide a solidification and re-greening structure for acidification of high and steep slopes, to solve the problems of high cost and unstable greening effect in the prior art during repair.

[0050] The solidification and re-greening structure for acidification of high and steep slopes provided by the present application has a position to be repaired, and the solidification and re-greening structure for acidification of high and steep slopes comprises:

[0051] A drainage ditch 1 is provided at the platform and edge of the high and steep slope;

[0052] A fixed net 2, a vegetation layer 3, a solid waste-based curing agent layer 4 and a non-woven fabric 5 are sequentially laid on the slope surface of the high and steep slope;

[0053] Among them, the fixed net 2 comprises a plurality of mesh holes arranged in an array, and the size of each mesh hole is 5cm×5cm.

[0054] Specifically, as shown in Figure 1 The solidification and re-greening structure for acidification of high and steep slopes provided by the present application comprises a drainage ditch 1 provided at the platform and edge of the high and steep slope. The way of providing the drainage ditch 1 at the platform and edge of the high and steep slope belongs to the prior art, and the specific construction method is disclosed in patent No. CN202010313392.2. Then, a fixed net 2, a vegetation layer 3, a solid waste-based curing agent layer 4 and a non-woven fabric 5 are sequentially laid on the slope surface of the high and steep slope. Among them, the fixed net 2 is a galvanized iron wire mesh, and the size of the mesh hole is 5cm×5cm. The vegetation layer 3 comprises tree seeds, shrub seeds and herb seeds. The weight ratio of the tree seeds, the shrub seeds and the herb seeds is (2-8):(10-20):(25-40). The solid waste-based curing agent layer 4 comprises 3-5 parts of S95 grade slag and 4-6 parts of composite alkali. The S95 grade slag belongs to the prior art, and the specific details are disclosed in patent No. CN101805142. The 4-6 parts of composite alkali belong to known materials, and the specific details are disclosed in patent No. CN114804675B.

[0055] The utility model provides a kind of solidification and re-greening structure of acidification high steep slope, by setting up intercepting and draining ditch 1 at high steep slope platform and edge, effectively prevent rainwater from the scouring of slope, reduce soil erosion, enhance the stability of slope.Fixed net 2 uses 18# galvanized iron wire net, mesh size 5cm×5cm, can effectively fix soil and vegetation, prevent the sliding and erosion of slope surface, provide good growth medium simultaneously, promote the extension of plant root system.

[0056] Vegetation layer 3 can not only quickly realize slope greening by imitating natural configuration of arbor shrub grass three-dimensional structure, but also form multi-level biological protection system, enhance the weathering resistance and soil conservation capacity of slope.Solid waste-based curing agent layer 4 includes S95 grade slag powder and composite alkali, uses solid waste material as curing agent, not only reduces repair cost, but also realizes the resource utilization of industrial solid waste, meets the requirements of environmental protection and sustainable development.

[0057] The use of non-woven fabric 5 covering layer can effectively maintain soil humidity, promote seed germination and seedling growth, and at the same time avoid the damage of rainwater scouring to new vegetation.

[0058] The use of solid waste-based curing agent realizes the environmental protection disposal and resource utilization of industrial solid waste, which helps to reduce environmental pollution.

[0059] The construction process of the solidification and re-greening structure is simple, the solidified soil layer forms quickly, greatly shortens the engineering period and reduces the personnel safety risk.The solidification and re-greening structure efficiently solves the problems of soil conservation, ecological restoration and anti-scouring of acidification high steep slope, has high vegetation coverage, forms arbor shrub grass three-dimensional community structure, not only enhances the stability of slope, but also beautifies the environment, realizes the dual benefits of ecology and landscape.

[0060] Further, the thickness of vegetation layer 3 is 8cm to 12cm; and / or,

[0061] The thickness of solid waste-based curing agent layer 4 is 3cm to 4cm.

[0062] The thickness of vegetation layer 3 is designed to be 8cm to 12cm, and this thickness selection aims to provide sufficient soil and growth medium support to ensure that the roots of arbor shrub plants can grow stably.The thicker vegetation layer 3 can improve the water retention and air permeability of the substrate, provide a good growing environment for plants, and effectively prevent soil erosion and enhance the stability of the slope.In addition, this thickness can promote the rapid growth of vegetation, form an effective covering layer in a short period of time, thereby reducing the exposure and erosion of the slope.

[0063] The thickness of the solid waste-based solidifying agent layer 4 is designed to be 3-4 cm, aiming to fully exert the performance of the solidifying agent while maintaining a balance between cost and construction efficiency. The solidifying agent layer of this thickness can effectively fix the slope gravel and acidified waste soil, improve the stability of the slope structure, and prevent landslides and collapses. At the same time, the thickness of the solidifying agent layer is moderate, which can ensure sufficient strength and durability to resist extreme weather conditions and the growth pressure of plant roots without increasing excessive material cost and construction difficulty. Further, the solidifying and greening structure further comprises:

[0064] The fixing structure comprises a plurality of first fixing rods, one end of each of the first fixing rods sequentially penetrating through the non-woven fabric 5, the solid waste-based solidifying agent layer 4, the vegetation layer 3, and the fixing net 2, and being uniformly inserted into the top of the position to be repaired;

[0065] The diameter of each first fixing rod is 14-16 mm.

[0066] One end of each first fixing rod sequentially penetrates through the non-woven fabric 5, the solid waste-based solidifying agent layer 4, the vegetation layer 3, and the fixing net 2, and is deeply inserted into the bedrock or stable soil layer of the slope, ensuring that all the repaired layers are tightly connected, and enhancing the integrity and stability of the solidifying and greening structure. This can effectively prevent the displacement and erosion of the vegetation layer 3 and the solid waste-based solidifying agent layer 4 under adverse weather conditions, especially for high and steep slopes, and such deep anchoring is the key to preventing slope landslides and soil loss.

[0067] By pre-providing the fixing structure, i.e., a plurality of first fixing rods with a diameter of 14-16 mm on the top of the slope, the subsequent steps of net fixing and mixture spraying in the construction process can be simplified, ensuring that the net and the solidifying and greening material can be quickly and accurately installed in place, reducing the construction time and improving the construction efficiency.

[0068] The presence of the fixing structure provides additional support and protection for the vegetation layer 3, especially during the initial growth stage of the vegetation, which can protect the seedlings from damage by the external environment. This helps the vegetation to form quickly, improves the speed of slope greening and ecological restoration, and can achieve a high plant coverage rate in a relatively short time to form an effective biological protection layer.

[0069] The use of first fixing rods with a moderate diameter not only provides sufficient fixing force, but also reduces material cost and construction difficulty. Compared with using thicker or more fixing materials, the fixing structure of the present application realizes reasonable control of cost while ensuring the stability of the slope, thereby reducing the economic burden of the overall repair project.

[0070] The diameter and anchoring depth of the first fixing rod can be adjusted according to the specific geological conditions and acidification degree of the slope, providing flexibility to adapt to different complex environments. This adjustability enables the solidification and greening structure to be widely applied to various types of acidified high and steep slopes, including metal mining areas, highway construction and mine reclamation scenes, and has strong applicability and promotional value.

[0071] Further, each fixing structure further comprises:

[0072] a plurality of second fixing rods, one end of the plurality of second fixing rods sequentially penetrating the non-woven fabric 5, the solid waste-based solidifying agent layer 4, the vegetation layer 3 and the fixing net 2, and being uniformly inserted into the slope surface at the position to be repaired;

[0073] wherein the diameter of each second fixing rod is 14 mm.

[0074] The arrangement of the second fixing rod provides multiple-point support for the vegetation layer, promotes the growth and extension of plant root systems into deep soil of the slope, increases the contact area between the root system and the soil, improves the soil fixation capacity of the plant and the biological stability of the slope, and accelerates the restoration of the slope ecosystem.

[0075] By uniformly arranging a plurality of second fixing rods on the slope surface, the steps of net laying and mixed material spraying and seeding in the construction process are simplified, ensuring that each layer of repair material can be stably fixed at the predetermined position, reducing the uncertainty in construction, improving the construction quality and efficiency, and shortening the construction period of the overall repair project.

[0076] The diameter of the second fixing rod is 14 mm, which is more delicate compared to the diameter of the first fixing rod. This not only provides sufficient fixing strength, but also reduces the amount of material used and construction costs. At the same time, the reasonable distribution of the second fixing rods reduces the damage to the soil of the slope, achieving the goals of resource conservation and environmental protection.

[0077] Further, the distance between each adjacent two first fixing rods is 2.5-3 m; and / or,

[0078] the distance between each adjacent two second fixing rods is 2.5-3 m; and / or,

[0079] the distance between the first fixing rod and the adjacent second fixing rod is 2.5-3 m.

[0080] Starting from the top of the slope, the first fixing rods are uniformly arranged with a distance of 2.5-3 m between adjacent two, ensuring the stability of the top of the slope. After laying the fixing net 2, the second fixing rods are uniformly arranged along the slope surface at a distance of 2.5-3 m, penetrating the non-woven fabric 5, the solid waste-based solidifying agent layer 4, the vegetation layer 3 and the fixing net 2, and penetrating into the soil of the slope surface, forming deep reinforcement of the slope.

[0081] Further, the first fixing rod comprises:

[0082] a first fixing part, the first fixing part being inside the position to be repaired, the length of the first fixing part being 35-40 cm;

[0083] a second fixing part, the second fixing part being arranged at one end of the first fixing part away from the inside of the position to be repaired, the second fixing part being outside the position to be repaired, the length of the second fixing part being 10-15 cm.

[0084] The first fixing part penetrates into the inside of the slope, and the length thereof is set to be 35-40 cm, which can ensure that the fixing rod is effectively anchored in the stable soil layer or rock layer of the slope, greatly enhancing the anti-sliding, anti-weathering and anti-erosion properties of the slope. Through deep anchoring, the solidification and greening structure can better resist the action of natural forces and maintain long-term stability.

[0085] The second fixing part is arranged at the distal end of the first fixing part and is outside the slope, and the length thereof is set to be 10-15 cm, which can effectively fix the galvanized iron wire mesh and the non-woven fabric 5, prevent displacement of the fixed net 2, the solid waste solidifying agent layer 4 and the vegetation layer 3 under the action of external forces such as wind and rainfall, thereby protecting the vegetation on the solidification and greening layer and ensuring that the growth environment of the plants is not destroyed, accelerating the process of slope greening and ecological restoration.

[0086] Further, the first fixing part and the second fixing part are integrally formed; or,

[0087] The first fixing part and the second fixing part are detachably arranged.

[0088] When the first fixing part and the second fixing part are integrally formed, this design simplifies the assembly steps in the on-site construction process, improves the installation efficiency, and at the same time ensures the overall strength and structural stability of the fixing rod. The integrally formed fixing rod can quickly penetrate through each layer of repair material during installation and reach the predetermined insertion depth, reducing the additional damage to the slope during construction and ensuring the integrity of the solidification and greening structure and the slope reinforcement effect.

[0089] The first fixing part and the second fixing part are detachably arranged, which provides convenience for later maintenance and replacement. During the process of ecological restoration of the slope, if the vegetation coverage of some areas decreases or the fixing effect weakens, the fixed net or non-woven fabric can be adjusted locally or the part of the first fixing part penetrating into the inside of the slope can be replaced by detaching the second fixing part, without the need to re-construct the entire fixing structure. This flexibility reduces maintenance costs, avoids secondary damage to the slope, and also facilitates optimization and adjustment according to the actual situation of the slope at different stages.

[0090] Whether it is integrated or detachable, the design of the first fixing rod can adapt to the changing construction environment and geological conditions. Integrated is suitable for stable construction conditions and requires quick installation. Detachable is more suitable for complex construction conditions or needs to be adjusted according to the site conditions. The choice of the two connection methods makes the solidification and greening structure of the utility model better adapt to different types of acidification high and steep slopes, and improves the adaptability and success rate of the repair project.

[0091] Further, the second fixing rod comprises:

[0092] The third fixing part is inside the position to be repaired, and the length of the third fixing part is 20-25 cm;

[0093] The fourth fixing part is provided at one end of the third fixing part away from the inside of the position to be repaired, and the fourth fixing part is outside the position to be repaired, and the length of the fourth fixing part is 10-15 cm.

[0094] Further, the third fixing part and the fourth fixing part are integrally formed; or,

[0095] The third fixing part and the fourth fixing part are detachably arranged.

[0096] Further, the fixing net 2 is a galvanized iron wire mesh.

[0097] The third fixing part is positioned inside the slope, and the length is 20-25 cm, which can penetrate into the slope body and ensure the close connection between the solidification and greening layer and the slope matrix. The length of the fourth fixing part is set to 10-15 cm, which is located outside the slope, and can effectively fix the galvanized iron wire mesh and the non-woven fabric 5, prevent the displacement of the fixing net 2 in the initial stage of plant growth, and protect the seedlings from damage by natural factors such as weathering and water erosion. This provides a safe and stable environment for the initial growth of vegetation and accelerates the greening process of the slope.

[0098] When the third fixing part and the fourth fixing part are integrally formed, the structural strength and construction efficiency of the second fixing rod are ensured, and the on-site assembly time is reduced. The detachable arrangement provides convenience for later maintenance and replacement, without the need to replace the fixing rod as a whole, reduces the maintenance cost, and improves the sustainability of the slope repair system.

[0099] The fixing net 2 adopts a galvanized iron wire mesh, which has good corrosion resistance and can maintain long-term stability and carrying capacity even in an acidification environment. The galvanized iron wire mesh is used in cooperation with the integrally formed or detachable second fixing rod, which further enhances the durability and biochemical chemical reinforcement effect of the entire solidification and greening structure.
