Description

Technical Field

[0001] The invention belongs to the technical field of slope protection, and in particular relates to an organic soil slope protection structure and a construction method thereof. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation include: changing the form of pollutants in the soil or the way they are combined with the soil, reducing their mobility and bioavailability in the environment; reducing the concentration of harmful substances in the soil.

[0003] In the process of soil remediation, soil conditioners are used as soil remediation products made of natural peat or other organic matter rich in organic matter and humic acid. They have the three most significant soil conditioning properties of "water retention, fertilizer increase, and air permeability", so they are widely used in soil remediation. However, traditional soil conditioners mainly use their chemical properties to break soil compaction, loosen soil, improve soil permeability, and reduce soil bulk density. Although this method has a certain role in improving and repairing soil, in soil and terrain conditions with high fluidity of the surface soil such as desertification areas, gully erosion areas, tailings areas, and rock and soil slopes, due to the high fluidity of the surface soil, it is impossible to form a soil holding layer on the soil surface in time. Therefore, when using traditional soil conditioners, they cannot effectively repair and protect the soil structure, which is easy to cause soil erosion.

[0004] Based on this, the present invention proposes an organic soil slope protection structure and a construction method thereof to solve the problems existing in the above-mentioned prior art. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an organic soil slope protection structure and a construction method thereof.

[0020] In a preferred embodiment, a plurality of clamping blocks are further arranged on the outer side of the limiting plate, and the clamping blocks match the limiting grooves provided on the inner wall of the anchor sleeve.

[0021] In a preferred embodiment, the organic soil conditioner comprises, by weight, 25 to 35 parts of wood fiber, 50 to 60 parts of herbal fiber, 5 to 10 parts of natural mineral microspheres containing rubidium, 1 to 4 parts of polypropylene fiber, 2 to 8 parts of colloidal adhesive, 1 to 7 parts of biological awakening agent, and 3-5 parts of polyvinyl acetate.

[0022] In a preferred embodiment, the laying thickness of the soil protection layer is 3-8 mm, and a coagulant is mixed in the soil protection layer, wherein the coagulant includes 85% of hydrocolloid polymer powder, 10% of mineral binder and 5% of concrete binder.

[0023] The present invention provides a second solution: a construction method of an organic soil slope protection structure, comprising:

[0024] Step 1: Level the site

[0025] Level the slope construction site and clear obstacles to obtain a flat slope base;

[0026] Step 2: Lay and fix the metal mesh on the slope base treated in step 1

[0027] Lay the metal mesh along the slope of the base layer, overlap the metal meshes in parallel, and the overlap width is 5 to 10 cm; after laying it flat and smooth, use anchor rods to fix the metal mesh from top to bottom, and after the mesh of the metal mesh is hung into the anchor rod, tie the wire tightly;

[0028] The distance between two adjacent anchors is 50cm, and they are arranged in a plum blossom shape. After the anchors are driven, a layer of soil is laid inside the metal mesh.

[0029] Step 3: Spray an organic soil conditioner containing grass seeds

This protective structure can effectively protect slopes in desertified areas, gully erosion areas, tailings areas, rock and soil slopes and other soils with high surface soil fluidity and terrain conditions by laying metal mesh, soil layer, organic soil layer and soil protection layer in sequence on the slope base, avoiding the flow of surface soil and solving the problem that the existing technology cannot effectively repair the soil structure with high surface soil fluidity.

[0034] 2. This slope protection method applies organic soil conditioner to the organic soil layer, polypropylene fibers are intertwined to form a support body with toughness and hardness, wood fibers and herbaceous fibers can better fill the gaps on the support body, and the colloidal adhesive can fix polypropylene fibers, wood fibers and herbaceous fibers on the soil surface. The biological awakening agent can awaken soil microorganisms, and wood fibers and herbaceous fibers can better provide sufficient nutrients for soil microorganisms. At the same time, due to the different time for wood fibers and herbaceous fibers to become organic matter, plants can continuously obtain nutrients for a relatively long time to meet the needs of plant growth, so that the plant roots can achieve the effect of soil fixation and water conservation, and realize the organic transformation of the slope surface soil layer; at the same time, the organic soil conditioner can form a continuous, porous, absorbable and flexible covering matrix on the soil surface, which can provide plant seeds with a good germination environment of temperature and humidity in harsh environments, and accelerate the process of seed germination and rooting. It is beneficial for plant roots to absorb soil nutrients, take root quickly and form plant communities.

[0035] 3. This protective structure can effectively ensure the fixing effect of the metal mesh on the slope base through the structural setting of the anchor rod. At the same time, the prestressed positioning plate can be expanded outward by adjusting the nut to form a prestressed anchoring force, thereby fixing the position of the anchor rod in the slope base, effectively ensuring the anchoring and slope management effect.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 10 The present invention provides a technical solution: a construction method of an organic soil slope protection structure, comprising:

[0049] Step 1: Level the site

[0050] Level the slope construction site and clear obstacles to obtain a smooth slope base for construction 6;

[0051] Step 2: Lay and fix the metal mesh 4 on the slope base 6 treated in step 1

[0052] Lay the metal mesh 4 along the slope of the slope base 6, and overlap the metal meshes 4 in parallel with each other, with an overlap width of 5 to 10 cm; after paving smoothly, fix the metal mesh 4 from top to bottom with anchor rods 5, and after the mesh of the metal mesh 4 is hung into the anchor rods, tighten the wires, wherein the spacing between two adjacent anchor rods is 50 cm and arranged in a plum blossom shape, and after the anchor rods 5 are installed, lay a soil layer 3 in the mesh of the metal mesh 4;

[0053] Step 3: Spray an organic soil conditioner containing grass seeds:

[0054] Mix the vegetation seeds and the organic soil conditioner, and spray the mixed organic soil conditioner containing the grass seeds with a sprayer to a thickness of 2-5 mm to form an organic soil layer 2;

[0055] Step 4: Finally, a soil protection layer 1 with a thickness of 3 to 8 mm is adhered to the surface of the organic soil layer 2, and after the seeds in the organic soil layer 2 germinate and grow, an ecological protection structure of the slope is formed;

[0056] The schematic diagram of the relationship between the laid metal mesh 4, the anchor rod 5, the organic soil layer 2, the soil protection layer 1 and the plants is shown in FIG. Figure 1 shown.

[0057] It should be noted that the above slope is a stable slope with excavated stone and a slope ratio not steeper than 1:0.5. After laying and fixing the metal mesh 4, it is necessary to cover the soil or fill the soil (soil layer 3); interception and drainage facilities need to be set up on the top of the excavated slope. At the same time, the above slope to be repaired is any one or more of poor soil, soil and rock slope and rock slope; among which, poor soil can be compacted soil, saline-alkali land, pickled soil with a salt content of more than 300g / kg, etc.; abandoned rock area or soil and rock area after mining, etc.

[0058] In a preferred embodiment, Figure 1 As shown, the soil protection layer 1 can be any kind of soil collected nearby, such as soil from saline-alkali land, pickled soil, compacted soil, etc. In specific implementation, the coagulant is mixed with the above soil and then sprayed onto the outside of the organic soil layer 2 of the area to be repaired.

[0059] It should be noted that the above-mentioned coagulant can be a coagulant for making low-strength bricks, and the coagulant mainly includes: 85% hydrocolloid polymer powder, 10% mineral binder and 5% concrete binder.

[0060] It is worth noting that, in the above-mentioned embodiment, by covering the soil protection layer 1 on the outside of the organic soil layer 2, the microorganisms in the organic soil layer 2 can be better awakened to ensure the growth of vegetation.

[0061] In a preferred embodiment, Figure 1 As shown, the organic soil layer 2 includes an organic soil conditioner and vegetation seeds mixed therewith; the vegetation seeds include any one or more of shrub seeds, herbaceous plant seeds and tree plant seeds, such as a mixture of shrub seeds and herbaceous plant seeds, wherein the shrub seeds can be a mixture of seeds of multiple shrubs, and the herbaceous plant seeds can be a mixture of seeds of multiple herbaceous plants.

[0062] It should be noted that the above-mentioned organic soil conditioner, calculated by weight, contains 25-35 parts of wood fiber, 50-60 parts of herb fiber, 5-10 parts of natural mineral microspheres containing rubidium, 1-4 parts of polypropylene fiber, 2-8 parts of colloidal adhesive, 1-7 parts of biological awakening agent, and 3-5 parts of polyvinyl acetate.

[0063] Among them, in the above organic soil conditioner:

[0064] The wood fiber is wood fiber that has been mechanically treated and heat treated, and the wood fiber can be wood fiber such as pine fiber, willow fiber, etc. In addition, the wood fiber can also come from wood processing scraps such as scraps generated in the furniture production process.

[0065] The herb fiber is a herb fiber that has been heat-treated and pasteurized, and the herb fiber can be cereal fiber, alfalfa fiber, jute fiber, etc., and can include 30% to 90% cereal straw and 10% to 70% alfalfa. In order to facilitate the degradation of wood fiber and herb fiber, and at the same time make the looseness and air permeability of the mesh structure meet the growth requirements of plants, the length of the wood fiber, the length of the herb fiber and the length of the polypropylene fiber are 5 to 30 mm.

[0066] The colloidal adhesive includes cellulose powder, anionic polyimide crystals and VAE powder. While being able to meet the viscosity requirements of the organic soil conditioner, the colloidal adhesive has the characteristics of being non-toxic, environmentally friendly and easy to degrade. In addition, the colloidal adhesive also has an anti-ultraviolet effect. Through testing, it is found that its degradation rate is generally about 12 months.

[0067] The pyrolysis-containing natural mineral microspheres include volcanic rocks and other broken rocks. Through testing, it was found that the mixture of volcanic rocks and other broken rocks can contain 64 kinds of minerals that can be used by plants or microorganisms, which can ensure better reproduction of soil microorganisms and better growth of plants. In order to enable the pyrolysis-containing natural mineral microspheres to be better utilized and to achieve a sustained-release effect, the diameter of the above-mentioned pyrolysis-containing natural mineral microspheres is 3 to 7 mm.

[0068] The biological awakening agent includes any one or more of monosaccharides, starch, protein, amino acids, vitamins and folic acid. The awakening effect on soil microorganisms can be ensured by adding the biological awakening agent.

[0069] By adding polyvinyl acetate, the water retention rate of the flexible porous fiber matrix formed by the organic soil conditioner covering the soil surface can be more than 1200% of the original soil water retention rate;

[0070] When the above organic soil conditioner is used, polypropylene fibers play a supporting role, and polypropylene fibers are degradable non-toxic organic matter; wood fibers and herbal fibers are mixed to play a filling role, and at the same time, wood fibers and herbal fibers supplement the carbon source required for plant growth after degradation; natural mineral microspheres containing chlorine can supplement minerals for plant growth; and the colloidal adhesive can fix polypropylene fibers, wood fibers and herbal fibers. Biological awakening agents are used to awaken microorganisms on the surface of the soil and provide nutrients to these microorganisms to promote the degradation of wood fibers and herbal fibers by microorganisms. They can not only regulate the pH value of the soil surface to suit plant growth, but also provide sufficient nutrients for plant growth, so that the growing plants can obtain relatively developed root systems. A developed plant root system is conducive to water conservation and soil consolidation.

[0071] It is worth noting that the preparation method of the above organic soil conditioner specifically includes the following steps:

[0072] Step S1: preparing the biological awakening agent into a biological awakening solution, wherein the ratio of the biological awakening agent to water in the biological awakening solution is 1:15 to 1:25;

[0073] Step S2: adding a gel adhesive to the biological awakening solution;

[0074] Step S3: soaking the wood fiber and the herbal fiber in the biological awakening solution for no less than 24 hours respectively;

[0075] Step S4: coating the bio-awakening solution onto the natural mineral microspheres containing rubidium;

[0076] Step S5: mixing the soaked wood fibers, the soaked herbal fibers, the coated natural mineral microspheres containing chlorine and the polypropylene fibers;

[0077] Through the above method, the biological awakening agent is coated on the surface of wood fiber, herbal fiber and natural mineral microspheres containing ruthenium, etc. On the one hand, it can ensure the uniformity of the dispersion of the biological awakening agent, and on the other hand, it can directly contact with the soil to awaken soil microorganisms.

[0078] In a preferred embodiment, Figure 1 and Figure 2As shown, the metal mesh 4 is anchored on the slope base 6 by anchor rods 5. Specifically, the upper end of the anchor rod 5 is a cut slope. When the "「" type anchor rod is used to fix the metal mesh 4, the anchor rod should be vertically nailed into the slope along the uppermost edge of the mesh, and the elbow should be nailed into the slope upward; when the "∩" type anchor rod is used to fix the metal mesh 4, the anchor rod opening is vertically nailed into the slope along the uppermost edge of the mesh downward; and when the metal mesh 4 is fixed by the anchor rods 5, the metal mesh 4 is fixed in a cross-arrangement manner using different lengths.

[0079] It should be noted that if Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in order to achieve an effective anchoring effect when anchoring and fixing the metal mesh 4, the anchor rod 5 is designed to include an anchor rod sleeve 51 and a prestressed anchoring mechanism arranged in the anchor rod sleeve 51; the anchor rod sleeve 51 is a hollow sleeve structure with anchoring threads arranged on the outer surface, and the front end of the anchor rod sleeve 51 is a conical structure with external threads, which is convenient for anchoring it in the slope base 6 when in use. A limited clamping block is arranged at the tail end of the anchor rod sleeve 51 to cooperate with the metal mesh 4, so that the anchor rod sleeve 51 can be overlapped on the outside of the metal mesh 4 to fix the metal mesh 4 regardless of whether it is a "" type structure or a "∩" type structure.

[0080] Furthermore, a plurality of clearance grooves 511 are layered on the anchor sleeve 51, and a prestressed positioning plate 52 is rotatably arranged in the clearance groove 511. The prestressed positioning plate 52 is rotatably installed in the clearance groove 511 through a torsion spring, and the prestressed positioning plate 52 is an L-shaped plate structure. A clearance platform 521 is also arranged at the lower end of the prestressed positioning plate 52 to match the prestressed anchoring mechanism. Under normal conditions, the prestressed positioning plate 52 is engaged in the clearance groove 511 along the length direction of the clearance groove 511. When in use, the prestressed anchoring mechanism is adjusted to make the prestressed positioning plate 52 rotate outward along its installation axis, forming a structure similar to an umbrella frame that is stretched outward and penetrates into the soil pores of the outer slope base 6, so as to achieve the positioning effect of the anchor sleeve 51 in the slope base 6. By using a torsion spring to rotatably install the prestressed positioning plate 52 in the clearance groove 511, the torsion force of the torsion spring can be used to fix the position of the prestressed positioning plate 52 in the clearance groove 511, so that the prestressed positioning plate 52 will not affect the anchor sleeve 51 during the anchoring process of the anchor rod 5.

[0081] Furthermore, the prestressed anchoring mechanism includes a plurality of movable disks 53, connecting strands 55 and limit disks 56. The movable disks 53 are movably arranged in the positioning plate 52, and are used in conjunction with the yielding platform 521 and the limit platform 512 arranged on the inner side of the anchor sleeve 51; the connecting strands 55 are arranged between two adjacent movable disks 53, and are used to connect the adjacent movable disks 53 and the movable disk 53 with the limit disk 56, so as to form a transmission structure that can both reduce the weight and can linkage-adjust the prestressed positioning plate 52 to rotate outward; the limit disk 56 is movably arranged at the upper end of the anchor sleeve 51, and is used in conjunction with the limit groove 513 arranged on the inner side of the upper end of the anchor sleeve 51, and an adjusting screw 58 is also arranged at the upper end of the limit disk 56, and the adjusting screw 58 passes through the plug 57 on the upper side of the anchor sleeve 51, and is threadedly connected to the adjusting nut 59.

[0082] It should be noted that, through the arrangement of the above-mentioned structure, after installation, the movable disk 53 is located at the lower side of the yield plate 521, the yield plate 521 is located at the lower side of the limit platform 512, and the distance between the yield plate 521 and the limit platform 512 can meet the rotation requirements of the yield plate 521. Therefore, after the anchor sleeve 51 is anchored at the corresponding position and depth, the staff adjusts the relative position relationship between the adjusting nut 59 and the adjusting screw 58 by rotating the adjusting nut 59, thereby adjusting the position of the movable disk 53 and the limit plate 56 in the anchor sleeve 51, so that the prestressed positioning plate 52 rotates outward along its installation axis, forming a structure similar to an umbrella frame that is stretched outward and penetrates into the soil pores of the outer slope base layer 6, so as to achieve the positioning effect of the anchor sleeve 51 in the slope base layer 6.

[0083] It is worth mentioning that:

[0084] In order to avoid the influence of gravity on the position of the movable disk 53 and the limit disk 56 in the anchor sleeve 51 after installation, a spring 54 is further provided at one end close to the tapered end of the lower end of the anchor sleeve 51. The upper end of the spring 54 is connected to the movable disk 53 at the corresponding position, so as to fix the position of the movable disk 53 at the front end by using the spring 54 when in use.

[0085] In order to prevent the limiting platform 512 from affecting the installation of the movable disk 53 during the installation of the movable disk 53, the limiting platform 512 is evenly arranged on the inner wall of the anchor sleeve 51 and used in conjunction with the clearance guide groove 532 provided on the movable disk 53, that is, when in use, by rotating the movable disk 53, when the limiting platform 512 and the clearance guide groove 532 at the corresponding position are in the same position, it is convenient to lower the movable disk 53 from the inner side of the anchor sleeve 51 to the position where it needs to be installed. At the same time, in order to facilitate the movable disk 53 after installation to push the clearance plate 521 to rotate when moving upward, a push plate 531 is also provided on the movable disk 53 to be used in conjunction with the clearance plate 521, and the push plate 531 moves in close contact with the inner wall of the anchor sleeve 51.

[0086] In order to avoid synchronous rotation of the limit plate 56 and the adjusting nut 59 during adjustment, which would affect the adjustment, a plurality of clamping blocks 561 are provided on the outer side of the limit plate 56 . The clamping blocks 561 are used in conjunction with the limit grooves 513 provided on the inner wall of the anchor sleeve 51 to limit the limit plate 56 .

[0087] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
