Description

Technical Field

[0001] This disclosure relates to the field of ecological restoration technology, and more specifically, to an ecological restoration structure for steep sandy silt slopes. Background Technology

[0002] Among related technologies, common ecological restoration methods for sandy silt slopes in the Loess Plateau region include: pit planting, horizontal terrace planting, fish-scale pit planting, and direct planting with living piles. Among these, pit planting, horizontal terrace planting, and fish-scale pit planting share similar principles, all creating suitable planting spaces on the slope and possessing a certain degree of soil and water conservation. However, due to construction technology limitations, the application of these methods on steep sandy silt slopes is limited. For example, when the slope is very steep, it is not only difficult to form planting pits, horizontal terraces, and fish-scale pits, but human disturbance may even cause new soil erosion and shallow landslides. While direct planting with living piles can adapt well to different slopes and soil layers, it also has some obvious drawbacks: First, due to the limitations of construction technology, it can only be used for planting some arborescent plants; second, arborescent plants grow slowly, and the vegetation cover is insufficient in the early stages of plant growth, so the improvement of soil and water loss in the treatment area will not be very obvious; third, after the trees have formed a forest, the tree species will increase the sliding force of sandy silt slopes, especially during the rainy season, which can easily cause shallow landslides.

[0003] Therefore, there is an urgent need to design an ecological restoration structure that can be applied to sandy silt slopes in the Loess Plateau region.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0035] In related technologies, ecological restoration of sandy silt slopes in the Loess Plateau region faces numerous challenges. Therefore, this disclosure provides an ecological restoration structure for steep sandy silt slopes (it is understood that the restoration structure provided in this disclosure is applicable not only to the ecological restoration of sandy silt slopes in the Loess Plateau region but also to slopes in other geological conditions), to achieve ecological restoration of sandy silt slopes in the Loess Plateau region. In this disclosure, see [link to relevant documentation]. Figure 1 , Figure 2 The slope 1 has a slag chute 11 and a soil accumulation area 12 arranged sequentially from top to bottom. The repair structure includes multiple first stabilizing structures 2 and second stabilizing structures 3. Multiple planting holes 111 are provided on the slag chute 11. The planting holes 111 facilitate the planting of plants on the slag chute 11. Multiple first stabilizing structures 2 are provided on one side of the planting holes 111 to stabilize the plants in the planting holes 111. Multiple second stabilizing structures 3 are provided on the soil accumulation area 12 to stabilize the slope of the soil accumulation area 12.

[0036] In this embodiment, a first stabilizing structure 2 is provided in the slag chute 11 to stabilize the plants planted in the slag chute 11, thereby solving the problem of slag chute sliding on the slope of the slag chute 11. A second stabilizing structure 3 is provided in the soil accumulation area 12 to stabilize the soil accumulation area 12, thereby reducing the slope instability caused by uneven deformation of the soil accumulation area 12. In this way, the combination of the first stabilizing structure 2 and the second stabilizing structure 3 can significantly reduce the problem of soil and water loss on the slope 1.

[0037] In some embodiments of this disclosure, see Figure 2 The first stabilizing structure 2 includes multiple stabilizing piles 21; wherein the multiple stabilizing piles 21 are set on the slag chute area 11, and the multiple stabilizing piles 21 are set corresponding to the planting holes 111. The set stabilizing piles 21 can play a certain stabilizing role for the growth of plants in the planting holes 111, so as to ensure the normal growth of plants while reducing the slag chute problem on the slope of the slag chute area 11.

[0038] It should be noted that in this embodiment, the number of stabilizing stakes 21 is not specifically limited, as long as the number of stabilizing stakes 21 corresponds to the number of planting holes 111 and can stabilize the plants in the planting holes 111.

[0039] Furthermore, in some embodiments, a portion of the stabilizing pile 21 extends beyond the corresponding slope, wherein the length of the stabilizing pile 21 extending beyond the slope is between 20 and 30 cm. For example, the length of the stabilizing pile 21 extending beyond the slope can be 20 cm, 24 cm, 28 cm, or 30 cm. It should be noted that in other embodiments, the length of the stabilizing pile 21 extending beyond the slope is not limited to this.

[0040] In some embodiments of this disclosure, see Figure 2 , Figure 3 The first stabilizing structure 2 also includes a stabilizing plate 22; the stabilizing plate 22 is connected to the portion of the stabilizing pile 21 that extends out of the slope. The stabilizing plate 22 forms a working platform for the workers, thus facilitating their work while stabilizing the vegetation in the slag dumping area 11.

[0041] As an example, along the width of the slag chute 11, multiple stabilizing plates 22 corresponding to multiple stabilizing piles 21 are integrally set. It is understood that the stabilizing plates 22 corresponding to multiple stabilizing piles 21 can be a single piece of stabilizing plate 22. In this way, on the one hand, the utilization efficiency of the first stabilizing structure 2 can be improved, and on the other hand, a single piece of stabilizing plate 22 makes it easy for workers to move freely on it, providing a working platform for workers.

[0042] In some embodiments of this disclosure, the width direction of the stabilizing plate 22 is the same as the length direction of the stabilizing pile 21, and one side of the stabilizing plate 22 contacts the slope surface of the slope 1 along the width direction of the stabilizing plate 22. This arrangement allows the stabilizing plate 22 to provide a working platform for workers while adjacent stabilizing plates 22 can form a closed space, reducing the problem of soil slurry slurry in the slurry sluice area 11. It should be noted that the width direction of the stabilizing plate 22 refers to the direction perpendicular to the plane of the slope 1.

[0043] Understandably, the installation of the stabilizing plate 22 and the stabilizing pile 21 can form a working platform for workers, which facilitates the construction of the repair structure; at the same time, it can also shorten the construction period of the repair structure and save construction costs to a certain extent.

[0044] In some embodiments of this disclosure, see Figure 1 , Figure 2 The second stabilizing structure 3 includes multiple vegetation bags 31; the multiple vegetation bags 31 are distributed within the soil accumulation area 12. The multiple vegetation bags 31 can stabilize the soil accumulation within the soil accumulation area 12, thereby reducing the slope instability problem caused by uneven deformation of the soil accumulation area 12.

[0045] As an example, see Figure 1Along the length of the soil accumulation area 12, there are multiple rows of planting bags 32, each row of planting bags 32 having multiple planting bags 31, with the planting bags 31 of adjacent rows of planting bags 32 being staggered. Plants can be sown or propagated by cuttings in the planting bags 31 according to the vegetation setting requirements.

[0046] In some embodiments of this disclosure, see Figure 1 The repair structure also includes multiple anti-slide piles 4; these piles 4 are located at the bottom of the slope 1, and are evenly distributed along the width of the slope 1. The anti-slide piles 4 can fix the toe of the slope 1 to prevent slope instability.

[0047] It should be noted that in this embodiment, there are multiple anti-slide piles 4, but this embodiment does not impose a specific limit on the number of anti-slide piles 4, as long as they can achieve the stability of the slope toe of the slope 1.

[0048] It is understood that in some implementations, anti-slide piles 4 may not be installed in the repair structure, and this application will not elaborate on this in detail.

[0049] In some embodiments of this disclosure, see Figure 1 , Figure 2 The repair structure also includes a raised embankment 5; the raised embankment 5 is located at the top of the slope 1, and the side of the raised embankment 5 away from the slope surface forms a blocking space with the plane where the top of the slope 1 is located. The raised embankment 5 can block the incoming water from the top of the slope 1 and reduce the erosion of the area to be treated by rainwater.

[0050] In some embodiments of this disclosure, see Figure 1 , Figure 2 The repair structure also includes a drainage ditch 6; the drainage ditch 6 is located at the top of the slope 1, on the side of the raised embankment 5 away from the slope surface. The drainage ditch 6 can collect water from the top of the slope 1, and the collected water can be used to irrigate the plants in the slag sluice area 11 and the vegetation bags 31 in the waterlogged area.

[0051] As an example, the restoration structure may also include a raised embankment 5 and a drainage ditch 6. The raised embankment 5 is located at the top of the slope 1, with the side of the raised embankment 5 away from the slope surface forming a blocking space with the plane where the top of the slope 1 is located. The drainage ditch 6 is located at the top of the slope 1, on the side of the raised embankment 5 away from the slope surface. The combination of the raised embankment 5 and the drainage ditch 6 can, on the one hand, intercept water coming from the top of the slope 1, reducing rainwater erosion of the area to be treated; on the other hand, the collected rainwater can be reused for later irrigation and maintenance of the slope vegetation. This improves water resource utilization while reducing slope safety risks.

[0052] In summary, the restoration structure disclosed herein can comprehensively consider the characteristics of soil and water loss at the toe, face, and top of slope 1, as well as the direction of ecological restoration, and carry out vegetation restoration on the basis of stabilizing the slope structure, thus achieving safety, economy, and applicability.

[0053] Furthermore, the repair structure disclosed herein is implemented in the following manner:

[0054] S1: At the toe of slope 1 in the proposed treatment area, determine whether anti-slide piles 4 need to be installed based on the slope's stability. It is understood that the installation of anti-slide piles 4 is determined by on-site personnel based on the slope's stability; in some repair structures, anti-slide piles 4 may not be required.

[0055] S2: Planting bags 31 are laid within the area between the top of the anti-slide pile 4 and the soil accumulation area 12, and plants can be sown or cut into the planting bags 31 according to the vegetation setting requirements.

[0056] S3: Horizontally lay out the contour lines within the range from the slag chute area 11 to the top of the slope. Starting from the lower part of the slag chute area 11, drive stabilizing piles 21 at equal intervals along the contour lines. If it is difficult to drive the stabilizing piles 21, a hand-held drilling machine can be used for pilot drilling. The length of the stabilizing piles 21 exposed on the slope surface is between 20 and 30 cm. Lay stabilizing boards 22 on the exposed wooden piles. One side of the stabilizing board 22 is laid close to the slope surface. The stabilizing board 22 and the stabilizing piles 21 are fixed with iron nails or other means. The stabilizing board 22 and the stabilizing piles 21 together form a working platform.

[0057] S4: The working platform is located close to the stabilizing pile 21 and the stabilizing plate 22. Planting holes 111 are dug according to the plant planting spacing, and plants are planted according to the vegetation setting requirements.

[0058] S5: Set up raised embankment 5 and intercepting ditch 6 in the water inflow area at the top of the slope.

[0059] It should be noted that the above-mentioned construction method for the repair structure adopts a step-by-step approach from the toe of the slope to the top of the slope. However, in other embodiments, the construction method for the repair structure is not limited to this (for example, it can be implemented from the top of the slope and the toe of the slope at the same time). This disclosure will not elaborate on this aspect.

[0060] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
