Description

Technical Field

[0001] The present disclosure relates to the technical field of ecological restoration, and in particular to a high-strength artificial soil layer reconstruction structure and a reconstruction method for a steep rock slope. Background Art

[0002] The spraying technology was first formed in the 1970s and is mainly used in highway slope greening, mine vegetation restoration, urban landscape greening and other projects. In slope ecological restoration projects, artificial soil reconstruction is usually carried out by using technologies such as hanging net spraying, vegetation bags, and hole planting. Among them, the hanging net spraying technology is to mix soil, organic matter, fertilizers, binders, water retaining agents, water and seeds in proportion according to the terrain characteristics of the slope and soil conditions, and then use a sprayer to spray them evenly on the slope surface in layers after mechanical stirring to form a spraying matrix. After the seeds in the matrix develop, a vegetation cover layer is formed, which has the effect of slope protection and greening. Its construction process is simple and low-cost, and it can adapt to slopes of different slopes and rock types by adjusting the ratio of ecological substrates. It is widely used in the slope ecological restoration market.

[0003] However, due to the influence of construction technology, the quality of spraying is difficult to control, especially for steep rock slopes. The surface matrix of spraying is easy to lose strength and gradually peel off under the influence of gravity and atmospheric precipitation, causing the degradation of ecological restoration effect. In recent years, with the further strengthening of the concept of ecological civilization, the requirements for ecological restoration of steep rock slopes have also been further improved. How to ensure the quality and stability of the artificial soil layer sprayed on steep rock slopes is also one of the hot points of slope ecological restoration technology.

[0025] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0026] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0027] Spraying technology is widely used in highway slope greening, mine vegetation restoration, urban landscape greening and other projects. However, in some construction conditions (such as high and steep rock slopes), the quality of spraying technology is difficult to control due to the influence and limitation of construction technology. The surface matrix of the spraying will easily lose strength and gradually peel off under the influence of gravity and atmospheric precipitation, causing the ecological restoration effect to deteriorate and seriously reducing the quality of slope ecological restoration.

[0028] Based on this, the embodiments of the present disclosure provide a high-strength artificial soil layer reconstruction structure and reconstruction method for steep rock slopes. The reconstruction structure and the reconstruction method using the reconstruction structure can significantly improve the stability and anti-scouring performance of the slope ecology compared with the prior art.

[0029] The first aspect of the present disclosure provides a high-strength artificial soil layer reconstruction structure for a steep rock slope, see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The reconstructed structure includes a first grid system 1, a first anchoring system 2, a second anchoring system 3, a gravity reduction system 4, a second grid system 5 and an artificial soil layer 6; the first grid system 1 is arranged on the slope through the first anchoring system 2; the gravity reduction system 4 is arranged on the side of the first grid system 1 away from the slope and is connected to the first anchoring system 2; the second grid system 5 is arranged on the side of the gravity reduction system 4 away from the first grid system 1 and is connected to the first anchoring system 2, and part of the second grid system 5 extends to the top of the slope; the second anchoring system 3 is used to fix the second grid system 5 at the top of the slope; the artificial soil layer 6 is arranged between the first grid system 1 and the second grid system 5, and part of the artificial soil layer 6 extends out of the side of the second grid system 5 away from the slope.

[0030] In the embodiment of the present disclosure, a three-dimensional artificial soil layer 6 skeleton is formed by connecting the first grid system 1, the second grid system 5, the first anchoring system 2, the second anchoring system 3 and the gravity reduction system 4. The three-dimensional artificial soil layer 6 skeleton can effectively support the reconstructed artificial soil layer 6, thereby enhancing the strength and scour resistance of the artificial soil layer 6. At the same time, the gravity reduction system 4 can block the fluid in the artificial soil layer 6, thereby preventing the substrate from sliding down under the action of gravity when the artificial soil layer 6 is sprayed, thereby causing construction defects.

[0031] In some embodiments of the present disclosure, see Figure 1 , Figure 2 The first grid system 1 includes a plurality of first subgrids 11 arranged along the slope direction of the slope, and adjacent first subgrids 11 are overlapped and fixedly connected, wherein the overlap length between adjacent first subgrids 11 is not less than 10 cm.

[0032] It is understandable that the area of ​​some slopes is large, and the specifications of the first subgrids 11 are limited, so multiple first subgrids 11 need to be spliced ​​to form a cover for the slope. However, it has been found that if the first grid system 1 is formed by splicing multiple first subgrids 11 together, the effect is not good in the subsequent use of the reconstructed structure (it will fail before the predetermined service life of the reconstructed structure), and there will be a phenomenon of looseness at the connection between adjacent first subgrids 11, which will lead to the failure of the reconstructed structure. Based on this, the method of first overlapping and then fixing the adjacent first subgrids 11 can significantly solve this problem. In subsequent further research, it was found that there are relatively ideal data for the overlap between adjacent first subgrids 11 (which can not only meet the service life of the reconstructed structure, but also reduce the number of first subgrids 11 used and reduce the construction cost of the reconstructed structure), that is, the length of the overlap between adjacent first subgrids 11 is not less than 10cm. It can be further understood that when the overlap length between adjacent first subgrids 11 is 10cm, it can meet the requirements under the predetermined service life of the reconstructed structure.

[0033] Of course, in some embodiments, the overlapping length between adjacent first sub-grids 11 may be greater than 10 cm.

[0034] As an example, the first subgrid 11 may be a flexible coconut net having a plurality of holes, wherein the flexible coconut net may have a diameter of 5 mm and the hole diameter may be 6×6 cm.

[0035] In some embodiments of the present disclosure, see Figure 1 , Figure 2 , Figure 5 , the first sub-grid 11 disposed near the top of the slope has a first bending section 111; wherein the width of the first bending section 111 is between 40 and 60 cm. For example, the length of the first bending section 111 can be 40 cm, 45 cm, 50 cm, 55 cm and 60 cm. It should be noted that in other embodiments, the length of the first bending section 111 is not limited thereto. In the embodiment of the present disclosure, the friction between the top of the first sub-grid 11 and the slope can be increased by setting the first bending section 111, thereby preventing the first sub-grid 11 from sliding down during paving, thereby ensuring the construction quality.

[0036] In some embodiments of the present disclosure, the first subgrid 11 disposed on both sides of the slope has a second bending section 112; wherein the width of the second bending section 112 is between 40 and 60 cm. For example, the length of the second bending section 112 can be 40 cm, 45 cm, 50 cm, 55 cm, and 60 cm. It should be noted that in other embodiments, the length of the second bending section 112 is not limited thereto. In the embodiments of the present disclosure, the connection strength between the first subgrid 11 and the slope can be further improved by providing the second bending section 112, so as to further reduce the phenomenon of sliding during the laying of the first subgrid 11.

[0037] As an example, the first sub-grid 11 arranged near the top of the slope has a first bending section 111; wherein the width of the first bending section 111 is between 40 and 60 cm; the first sub-grid 11 arranged near both sides of the slope has a second bending section 112; wherein the width of the second bending section 112 is between 40 and 60 cm.

[0038] It is understandable that in Figure 5 In the figure, relevant examples are given for the first bending section 111 and the second bending section 112. Since the first bending section 111 and the second bending section 112 are difficult to illustrate with drawings during the back pressure, dotted lines are used in the drawings of this application to indicate the folds of the first bending section 111 and the second bending section 112.

[0039] In some embodiments of the present disclosure, see Figure 2 The first anchoring system 2 includes a first anchor rod 21 arranged in an array on the slope surface; the first anchor rod 21 is fixedly connected to the first sub-grid 11; in some embodiments, the contact between the first sub-grid 11 and the first anchor rod 21 can be tied with wire.

[0040] As an example, the length of the first anchor rod 21 is between 50 and 100 cm; for example, the length of the first anchor rod 21 can be 50 cm, 60 cm, 70 cm, 80 cm, 90 cm or 100 cm. It should be noted that in other embodiments, the length of the first anchor rod 21 is not limited thereto.

[0041] In some embodiments, the first anchor rod 21 can be made of hot-rolled steel strip with a diameter of 14 cm. When the first anchor rod 21 is inserted into the slope, the hole inclination angle of the first anchor rod 21 can be between 5° and 20°. At the same time, the first anchor rod 21 should be inserted into the bedrock of the slope to a certain depth during construction. For broken or relatively broken rock masses, the anchor rod can be installed by "grouting first and then inserting the rod" to ensure the stability of the first anchor rod 21.

[0042] As another example, the distance between adjacent first anchor rods 21 is between 0.5 and 1.5 m. For example, the distance between adjacent first anchor rods 21 may be 0.5 m, 0.8 m, 1.2 m or 1.5 m. It should be noted that in other embodiments, the distance between adjacent first anchor rods 21 is not limited thereto.

[0043] It can be understood that in the embodiment of the present disclosure, the first anchor rods 21 are arranged in an array on the slope surface, and adjacent first anchor rods 21 refer to first anchor rods 21 adjacent along the length direction of the slope and first anchor rods 21 adjacent along the width direction of the slope. Of course, the number of first anchor rods 21 arranged in some steep slope areas or local anti-steep areas can be adjusted (the distance between adjacent first anchor rods 21 may not be limited to 0.5~1.5m).

[0044] In some embodiments, see Figure 2 , Figure 4 The gravity reduction system 4 includes an array of eco-rods 41 ; wherein, along the width direction of the slope, the sides of adjacent eco-rods 41 that are close to each other are fixedly connected to the same first anchor rod 21 .

[0045] As an example, the eco-rod 41 can be made of materials such as PP fiber bags, and the bags are filled with planting soil, organic materials, organic fertilizers and compound fertilizers. The eco-rod 41 is arranged perpendicular to the axial direction of the first anchor rod 21, and the spacing between adjacent eco-rods 41 along the length direction of the slope is between 1 and 2 meters. Along the width direction of the slope, both ends of the eco-rod 41 can be fixed to the anchor rod with iron wires.

[0046] As another example, for steep slopes above 70° or when the thickness of the artificial soil layer 6 is greater than 12 cm, hard materials such as wooden boards can be arranged in intervals with the ecological rods 41 .

[0047] In some embodiments, the second grid system 5 includes a plurality of second sub-grids 51 arranged along the slope direction of the slope and a third sub-grid 52 arranged at the top of the slope; the second sub-grids 51 are connected to the third sub-grids 52; adjacent second sub-grids 51 are overlapped and fixedly connected, wherein the overlap length between adjacent second sub-grids 51 is not less than 10 cm.

[0048] It should be noted that, in this embodiment, the second sub-grid 51 can be tied and fixed to the first anchor rod 21 through a wire mesh.

[0049] As an example, the material of the second sub-grid 51 and the third sub-grid 52 can be plastic galvanized wire mesh, and the second sub-grid 51 and the third sub-grid 52 both have a plurality of mesh ports, and the specification of the mesh ports is 5×5 cm.

[0050] In some embodiments of the present disclosure, the second anchoring system 3 includes a plurality of second anchor rods 31 arranged along the length direction of the top of the slope; the second anchor rods 31 pass through the third sub-grid 52, and the second anchor rods 31 and the third sub-grid 52 can be fixedly connected by wire binding.

[0051] As an example, the second anchor rod 31 can be set at the top of the slope to fix the third sub-grid 52, thereby improving the fixing effect of the second grid system 5 on the slope. Further, the second anchor rod 31 can be made of hot-rolled steel strip with a diameter of 18 cm, and the length of the second anchor rod 31 can be between 50 and 100 cm.

[0052] Meanwhile, it should be noted that, in some embodiments, in the reverse slope area of ​​the slope, the laid second sub-grid 51 is far away from the slope surface, and rivets and other measures can be used to bring the wire mesh close to the rock wall.

[0053] In some embodiments of the present disclosure, see Figure 2 The artificial soil layer 6 includes a base layer 61 and a surface layer 62 which are stacked.

[0054] As an example, the base layer 61 may include planting soil, organic materials for habitat substrates, cement and habitat substrate improvers, etc.; the surface layer 62 may include plant seeds. Specifically, before spraying the artificial soil layer 6, the artificial soil layer 6 needs to be stirred evenly and then sprayed on the slope surface in batches, with each spraying thickness of 2 cm. After reaching a certain intensity, the next spraying is carried out until the designed thickness is reached.

[0055] In some embodiments of the present disclosure, the distance between the second grid system 5 and the first grid system 1 is 0.5 to 0.7 times the thickness of the artificial soil layer 6. For example, the distance between the second grid system 5 and the first grid system 1 can be 0.5 times, 0.6 times, 0.66 times, or 0.7 times the thickness of the artificial soil layer 6. It should be noted that in other embodiments, the relationship between the distance between the second grid system 5 and the first grid system 1 and the thickness of the artificial soil layer 6 is not limited to this.

[0056] See also Figure 6 A second aspect of the present disclosure provides a method for reconstructing a high-strength artificial soil layer on a steep rock slope, the method comprising: S1: Setting a first grid system 1 on the slope surface.

[0057] Specifically, before setting the first grid system 1 on the slope surface, it is necessary to drain and clean the top of the slope.

[0058] The drainage operation can be carried out in the following manner: when draining the top of the slope, a drainage ditch 7 can be set at a distance from one end of the top of the slope (of course, a water retaining sill can also be set, and the embodiment of the present disclosure takes the drainage ditch 7 as an example for explanation), and drainage ditches are set on both sides of the slope, and the drainage ditches are connected to the drainage ditch 7 so that the collected water at the top of the slope can be led to the outside of the slope.

[0059] Further, the intercepting ditch 7 can be made of concrete structure or flexible material. Meanwhile, rapids troughs and energy dissipation pools can be arranged in steep slope areas.

[0060] The cleaning operation can be carried out in the following ways: cleaning the slope surface according to the slope topography and rock conditions, removing loose deposits and dangerous rock on the surface of the slope to ensure the safety of the slope, and at the same time carrying out small-scale cutting and backfilling to ensure the overall flatness of the slope.

[0061] Setting the first grid system 1 on the slope surface includes: the first grid system 1 includes a plurality of first sub-grids 11. When setting the first grid system 1, the plurality of first sub-grids 11 are laid one by one on the slope surface, and adjacent first sub-grids 11 are overlapped and fixedly connected, wherein the overlap length between adjacent first sub-grids 11 is not less than 10 cm.

[0062] Furthermore, it is necessary to back-press the first sub-grid 11 near the top of the slope to form a first bending section 111, and control the width of the first bending section 111 to be between 40 and 60 cm; and it is necessary to back-press the first sub-grid 11 near the side of the slope to form a second bending section 112; wherein, the width of the second bending section 112 is controlled to be between 40 and 60 cm.

Meanwhile, the horizontal and vertical spacing between adjacent first anchor rods 21 is maintained at 1 m.

[0065] S3: Arrange the gravity reduction system 4 on the first grid system 1 , and connect the gravity reduction system 4 to the first anchoring system 2 .

[0066] Specifically, as an example, the gravity reduction system 4 can be an ecological rod 41. Furthermore, the ecological rod 41 can be made of materials such as PP fiber bags, and the specifications are 8 to 12 cm in diameter according to the thickness of the spraying layer, and the bags are filled with planting soil, organic materials, organic fertilizers and compound fertilizers. In addition, along the width direction of the slope, both ends of the ecological rod 41 can be fixed to the first anchor rod 21 with iron wires, and the adjacent ecological rods 41 are fixed to the same first anchor rod 21 on the side close to each other.

[0067] S4: a second grid system 5 is arranged on the gravity reduction system 4 , a part of the second grid system 5 extends to the top of the slope, and the second grid system 5 is connected to the first anchoring system 2 .

[0068] Specifically, after the gravity reduction system 4 is installed, a second grid system 5 is set on the slope surface, for example, a second subgrid 51 is set on the slope surface, and a third subgrid 52 is set on the top of the slope. The second subgrid 51 is tied and fixed to the first anchor rod 21 by wire.

[0069] S5: Use the second anchoring system 3 to fix the portion of the second grid system 5 located at the top of the slope.

[0070] Specifically, the second anchoring system 3 includes a plurality of second anchor rods 31, which are inserted into the top of the slope, and the third subgrid 52 is fixed to the second anchor rods 31 using wires, thereby fixing the third subgrid 52 on the top of the slope.

[0071] S6: After the second grid system 5 is installed, the artificial soil layer 6 is sprayed.

[0072] Specifically, after the second grid system 5 is installed, the base layer 61 and the surface layer 62 are sprayed on the second grid in sequence to form the artificial soil layer 6. On the day after the artificial soil layer 6 is sprayed, a non-woven fabric (or straw curtain) can be used to cover the spraying surface to perform slope maintenance, including pest control, fertilization, watering, and seedling replacement.
