Abstract
Description
Technical Field
[0001] This invention relates to the field of geological and ecological restoration technology, and more specifically, to a construction method for slope support and ecological restoration. Background Technology
[0002] In the construction of infrastructure such as roads, railways, water conservancy, and mines, the formation of artificial slopes is inevitable, and their stability directly determines the safety of subsequent projects and the integrity of the surrounding ecological environment.
[0003] Currently, most traditional slope protection technologies adopt a uniform support method, which can lead to over-support of slopes in stable road sections, resulting in a waste of resources. In high-risk road sections, slopes may become unstable due to insufficient support strength, and the surrounding ecological environment may also be damaged. Summary of the Invention
[0004] The problem addressed by this invention is how to ensure the stability of slope support while avoiding over-support.
[0005] To address the above problems, this invention provides a construction method for slope support and ecological restoration.
[0006] This invention provides a construction method for slope support and ecological restoration, comprising: dividing the slope into multiple construction sections along the horizontal direction according to the geological environment; dividing each construction section into multiple secondary slopes along the vertical direction according to the height of each construction section; and carrying out support construction and / or ecological restoration construction on the secondary slopes according to the height position and slope ratio of the secondary slopes and the construction section in which each secondary slope is located.
[0007] The beneficial effects of the construction method for slope support and ecological restoration of this invention are: This method, by dividing construction sections horizontally according to geological environment, can distinguish the differences in soil and rock stability in different road sections. Furthermore, by dividing secondary slopes vertically, it can accurately identify the stress characteristics and risk levels of slopes at different depths within the same construction section. Based on these divisions, differentiated support schemes can be developed for different secondary slopes. For example, for secondary slopes in stable road sections, only basic support or ecological restoration can be used, avoiding the over-support problem of traditional uniform support models and significantly reducing the consumption of support materials and construction costs. For secondary slopes in high-risk road sections, high-strength support structures combined with ecological restoration are used according to their slope ratio and height location to ensure that the support strength is sufficient to resist the risk of slope instability. This fundamentally avoids safety accidents such as landslides and collapses caused by insufficient support, while also preserving the original ecology of the slope to the maximum extent, reducing the damage to the surrounding environment during construction, and achieving coordinated development of engineering safety and ecological protection.
[0008] Optionally, the step of dividing the slope into multiple construction sections in the horizontal direction according to the geological environment specifically includes: dividing the slope into multiple construction sections in the horizontal direction according to the type of surface soil, the thickness of surface soil, the degree of weathering of the underlying rock layer, and the thickness of the underlying rock layer.
[0009] Optionally, it further includes: classifying the slope into a strong stability level, a high risk level, and a transitional level based on the surface soil type, surface soil thickness, weathering degree of the underlying rock layer, and thickness of the underlying rock layer, and matching each construction section with one of the strong stability level, the high risk level, and the transitional level.
[0010] Optionally, the step of dividing each construction segment into multiple secondary slopes along the height direction according to the height of each construction segment specifically includes: dividing each construction segment into a secondary slope every 10m from bottom to top in the height direction.
[0011] Optionally, the step of carrying out support construction and / or ecological restoration construction on each of the secondary slopes according to their height, slope ratio, and the construction section in which they are located specifically includes: if the secondary slope is located in the construction section of the strong stability level, then support construction combined with ecological restoration construction is adopted; if the secondary slope is located in the construction section of the high risk level, then support construction is adopted; if the secondary slope is located in the construction section of the transition level, then ecological restoration construction is adopted.
[0012] Optionally, the steps of supporting each of the secondary slopes specifically include: anchor bolt construction, anchor cable construction, and lattice beam construction for the secondary slopes.
[0013] Optionally, the steps of carrying out ecological restoration construction on each of the secondary slopes specifically include: carrying out one of the following construction methods on the secondary slopes: hydroseeding, netting, and framework-based grass protection.
[0014] Optionally, it also includes: carrying out drainage construction while carrying out support construction or ecological restoration construction on the secondary slope.
[0015] Optionally, after the step of supporting and / or ecologically restoring the secondary slope, the method further includes monitoring the secondary slope located at the highest point in each construction segment.
[0016] Optionally, the step of monitoring the secondary slope located at the highest point in each of the construction sections specifically includes: monitoring the slope top displacement, slope top movement speed, and slope top movement direction of the secondary slope located at the highest point in each of the construction sections.

[0022] like Figure 1 and Figure 2 As shown, this invention provides a construction method for slope protection and ecological restoration, including: S100: Based on the geological environment, the slope is divided into multiple construction sections 10 along the horizontal direction; S200: Based on the height of each construction section 10, each construction section 10 is divided into multiple secondary slopes 20 along the height direction; S300: Based on the height and slope of the secondary slope 20, carry out support construction and / or ecological restoration construction on the secondary slope 20.
[0023] In this embodiment, the slope is divided into construction sections 10 according to the geological environment along its horizontal extension direction using the above method. This distinguishes the differences in the stability of the soil and rock masses in different road sections. Furthermore, secondary slopes 20 are divided along the height direction, which can accurately identify the stress characteristics and risk levels of slopes at different depths within the same construction section 10. Based on the above division results, differentiated support schemes can be formulated for different secondary slopes 20. For example, for secondary slopes 20 in stable construction sections, only basic support or ecological restoration is used, avoiding the over-support problem in the traditional uniform support model and significantly reducing the consumption of support materials and construction costs. For secondary slopes 20 in high-risk construction sections, high-strength support structures are used in conjunction with ecological restoration according to their slope ratio and height position to ensure that the support strength is sufficient to resist the risk of slope instability. This fundamentally avoids safety accidents such as landslides and collapses caused by insufficient support, while also preserving the original ecology of the slope to the maximum extent, reducing the damage to the surrounding environment during construction, and achieving the coordinated development of engineering safety and ecological protection.
[0024] Optionally, the step of dividing the slope into multiple construction sections 10 in the horizontal direction according to the geological environment includes: dividing the slope into multiple construction sections 10 in the horizontal direction according to the type of surface soil, the thickness of surface soil, the degree of weathering of the underlying rock layer and the thickness of the underlying rock layer.
[0025] Using the above method, the division of construction section 10 is based on parameters such as surface soil type and surface soil thickness, which can provide a basis for subsequent support and ecological restoration plans. This can ensure that the geological environment within each construction section 10 is consistent and stable, laying the foundation for subsequent differentiated construction.
[0026] In this embodiment, the horizontal direction is the direction of slope extension.
[0027] Optionally, it further includes: classifying the slope into a strong stability level, a high risk level, and a transitional level based on the surface soil type, surface soil thickness, weathering degree of the underlying rock layer, and thickness of the underlying rock layer, and matching each construction section with one of the strong stability level, the high risk level, and the transitional level.
[0028] In this embodiment, for example, the slope is divided into six construction sections 10, namely K0+000~K0+160, K0+513~K0+580, K0+580~K0+634.837, K0+634.837~K0+640, K0+640.000~K0+929.562, and K0+929.562~K1+124.045.
[0029] The surface layer of the section from K0+000 to K0+160 is stiff plastic sandy clay, about 17 to 20 meters thick. The lower part consists of completely weathered granite, strongly weathered granite, and moderately weathered granite. The completely weathered granite is about 15 to 21 meters thick, the strongly weathered granite is about 10 to 12 meters thick, and the moderately weathered granite has not penetrated. This section is classified as a strong stability level.
[0030] The surface layer of the section from K0+513 to K0+580 is stiff plastic sandy clay soil, about 8 to 20 meters thick. The lower part is completely weathered granite, strongly weathered granite, and moderately weathered granite. The completely weathered granite is about 8 to 13 meters thick, the strongly weathered granite is about 17 to 39 meters thick, and the moderately weathered granite has not penetrated. This section is classified as high-risk.
[0031] The surface layer of the section from K0+580 to K0+634.837 is stiff plastic sandy clay soil, about 0 to 8 meters thick. The lower part is completely weathered granite, strongly weathered granite, and moderately weathered granite. The completely weathered granite is about 3 to 8 meters thick, the strongly weathered granite is about 28 to 38 meters thick, and the moderately weathered granite has not penetrated. This section is classified as high-risk.
[0032] The surface layer of the section from K0+634.837 to K0+640 is stiff plastic sandy clay soil, about 0 to 8m thick. The lower part is completely weathered granite, strongly weathered granite, and moderately weathered granite. The thickness of the completely weathered granite is about 6 to 17m, the thickness of the strongly weathered granite is about 22 to 43m, and the moderately weathered granite has not penetrated. This section is classified as a transitional danger level.
[0033] The surface layer of the section from K0+640.000 to K0+929.562 is stiff plastic sandy clay soil, about 0 to 5 meters thick. The lower part is completely weathered granite, strongly weathered granite, and moderately weathered granite. The thickness of the completely weathered granite is about 6 to 17 meters, the thickness of the strongly weathered granite is about 22 to 43 meters, and the moderately weathered granite has not penetrated. This section is classified as a transitional danger level.
[0034] The surface layer of the section from K0+929.562 to K1+124.045 is stiff plastic sandy clay soil, about 0 to 6m thick. The lower part is completely weathered granite, strongly weathered granite, and moderately weathered granite. The completely weathered granite is about 6 to 17m thick, the strongly weathered granite is about 22 to 43m thick, and the moderately weathered granite has not penetrated. This section is classified as strongly stable.
[0035] Optionally, the step of dividing each construction segment 10 into multiple secondary slopes 20 along the height direction according to its own height specifically includes: dividing each construction segment 10 into a secondary slope 20 every 10m from bottom to top in the height direction.
[0036] The above methods can quantify and subdivide the standards, thereby more accurately adapting to the stress characteristics and stability requirements of slopes at different heights, avoiding insufficient construction precision caused by excessively large construction section heights, and also providing a basis for the standardization of subsequent construction processes and the controllability of construction quality.
[0037] In this embodiment, if the height of the last slope after segmentation is less than 10m, the height of the last slope is calculated according to the actual dimensions.
[0038] Of course, in other embodiments, secondary slopes 20 can also be divided in the height direction according to other values.
[0039] Optionally, the steps for supporting each secondary slope 20 include: anchor bolt construction, anchor cable construction, and lattice beam construction for the secondary slope 20.
[0040] In this embodiment, the requirements for anchor bolt construction are as follows: a dedicated anchor bolt machine is used for dry drilling, and the hole diameter, positioning deviation, inclination, and drilling depth are strictly controlled; the anchor bar is made using sleeve connection; pure cement grout is used as the grouting material, and the water-cement ratio and grout strength are controlled; the anchor bolt is a full-length bonded type and undergoes strict anti-corrosion treatment (such as setting PVC sleeves at the hole opening and ensuring the thickness of the protective layer); a basic anchor bolt test is conducted before construction.
[0041] In this embodiment, the requirements for anchor cable construction are as follows: dry drilling should be used, and appropriate anchorage models should be selected; steel pipes should be reserved for anchor cables on piles; pure cement grout should be used as the grouting material, and the water-cement ratio and grout strength should be controlled; multiple anti-corrosion treatments should be applied to the outer anchor head, free section, and anchorage section of the permanent anchor cable; a two-stage grouting construction process should be adopted; anchor cable tensioning should be carried out after the grout strength reaches 80% of the design value, and the tensioning sequence, load, and stress should be strictly controlled; basic anchor cable tests should be conducted and monitored before construction.
[0042] In this embodiment, the requirements for the construction of the lattice beam are as follows: before construction, remove loose soil from the slope and fill the grooves; use semi-embedded grooved formwork for in-situ casting, and the concrete strength grade shall not be lower than C25; the fabrication and installation of steel bars shall comply with the specifications; and expansion joints shall be set at regular intervals for the lattice beam.
[0043] Optionally, the steps for ecological restoration construction of each secondary slope 20 include: hydroseeding, netting, and framework-based grass protection construction.
[0044] In this embodiment, the requirements for hydroseeding are as follows: level the slope, wet-sow a mixture of materials (including seeds, compound fertilizer, soil stabilizer, etc.) of a certain thickness (e.g., 100mm), cover it with non-woven fabric immediately after spraying, and carry out post-sowing management (irrigation, fertilization, pest and disease control).
[0045] In this embodiment, the requirements for the netting and grass planting construction are as follows: clean up the residual concrete on the slope, lay and fix the rust-proof and corrosion-proof machine-woven galvanized hook flower net; spray the organic substrate twice (base layer and surface layer), the spraying thickness is determined according to the slope (e.g., 15cm thick), cover with non-woven fabric after spraying, and carry out post-sowing management.
[0046] In this embodiment, the requirements for the construction of the skeleton grass protection are as follows: for slopes that have been basically stabilized, after cleaning the slope surface, a herringbone skeleton and water-cutting ribs are built using C25 precast blocks. After the skeleton construction is completed, grass is sprayed inside the skeleton. After spraying, non-woven fabric can be used for covering and maintenance.
[0047] In one specific embodiment, the step of carrying out support construction and / or ecological restoration construction on each of the secondary slopes 20 according to their height position and slope ratio and the construction section 10 in which each of the secondary slopes 20 is located specifically includes: if the secondary slope 20 is located in the construction section 10 of the strong stability level, then support construction combined with ecological restoration construction is adopted; if the secondary slope 20 is located in the construction section 10 of the high risk level, then support construction is adopted; if the secondary slope 20 is located in the construction section 10 of the transition level, then ecological restoration construction is adopted.
[0048] In this embodiment, for example, the section from K0+000 to K0+160 is classified as highly stable, requiring a combination of support construction and ecological restoration. Specifically, the section from K0+000 to K0+160 has three secondary slopes 20 arranged sequentially from bottom to top. The first secondary slope 20 uses a frame structure with anchor bolts for protection, and hydroseeding is applied within the frame, with a slope ratio of 1:1. The second secondary slope 20 uses a herringbone frame with wire mesh and grass planting for protection, with a slope ratio of 1:2. The third secondary slope uses wire mesh and grass planting for protection, with a slope ratio of 1:2.
[0049] In this embodiment, the section from K0+513 to K0+580 is classified as high-risk, so support construction is adopted. Specifically, the section from K0+513 to K0+580 has five secondary slopes arranged from bottom to top. The first, second, third, fourth, and fifth slopes are all protected by frame beams and anchor cables, and the slope ratios are 1:1, 1:1, 1:1, 1:0.75, and 1:0.75, respectively.
[0050] In this embodiment, the section from K0+580 to K0+634.837 is classified as high-risk, and therefore, support construction is employed. Specifically, the section from K0+580 to K0+634.837 has seven secondary slopes 20 arranged sequentially from bottom to top. The first secondary slope 20 is protected by anchor cable frame beams with a slope ratio of 1:1.5. The second, third, fourth, fifth, sixth, and seventh secondary slopes 20 are protected by anchor cables combined with frames and anchor bolts, with slope ratios of 1:1.5, 1:1.5, 1:1.25, 1:1, 1:1.5, and 1:0.75, respectively.
[0051] In this embodiment, the section from K0+634.837 to K0+640 is a transitional level, with five secondary slopes 20 arranged sequentially from bottom to top. Ecological restoration construction should be adopted. Specifically, the first, second, third, and fourth secondary slopes 20 are protected by herringbone mesh and grass planting, with a slope ratio of 1:2. The fifth secondary slope 20 is protected by hydroseeding and grass planting, with a slope ratio of 1:2.
[0052] In this embodiment, the section from K0+640.000 to K0+929.562 is a transitional level, with five secondary slopes 20 arranged sequentially from bottom to top. Ecological restoration construction should be adopted. Specifically, the first, second, third, and fourth secondary slopes 20 are all protected by herringbone mesh and grass planting, with a slope ratio of 1:2. The fifth secondary slope 20 is protected by hydroseeding and grass planting, with a slope ratio of 1:2.
[0053] In this embodiment, the section from K0+929.562 to K1+124.045 is classified as highly stable, with six secondary slopes 20 arranged sequentially from bottom to top. Therefore, a combination of support construction and ecological restoration should be employed. Specifically, the first and second secondary slopes 20 are protected using a grid beam structure with a slope ratio of 1:1. The third, fourth, and fifth secondary slopes 20 are protected using a herringbone framework with netting and grass planting, with slope ratios of 1:1.5, 1:2, and 1:2, respectively. The sixth secondary slope 20 is protected using hydroseeding with a slope ratio of 1:2.
[0054] Optionally, it also includes: carrying out drainage construction while performing support construction or ecological restoration construction on the secondary slope 20.
[0055] The above methods can eliminate the adverse effects of rainwater or groundwater on the secondary slope 20 during construction. On the one hand, they can promptly drain surface water that seeps into the secondary slope 20 during support or ecological restoration operations, avoiding problems such as softening of expansive soil and liquefaction of sandy soil. On the other hand, they can reduce the pore water pressure of the secondary slope 20 in advance, preventing local collapse of the secondary slope 20 due to water pressure accumulation, and providing a stable construction environment for the support structure (or ecological substrate) to ensure the effectiveness of subsequent projects.
[0056] Optionally, the drainage construction steps for the secondary slope 20 specifically include: setting up at least one of the following on the secondary slope 20: top intercepting ditch, platform drainage ditch, slope toe ditch, slope rapid flow channel, drainage ditch, and gravel blind ditch.
[0057] In this embodiment, the cut-off drainage ditch is located at the crest of the secondary slope 20, 5.0 m outside the slope edge line. The section of the drainage ditch is determined as needed. The drainage ditch is made of C20 cast-in-place concrete. A 50×50cm rectangular drainage ditch is used when the ground slope is gentler than 1:5, and a 50×hcm trapezoidal drainage ditch is used when the ground slope is steeper than 1:5. The location of the hillside drainage ditch can be adjusted appropriately based on the actual conditions after excavation.
[0058] In this embodiment, the platform intercepting ditch is set on the secondary slope of the multi-stage excavation platform 20, and a 40×40cm platform drainage ditch is adopted.
[0059] In this embodiment, a cover plate is provided at the toe of the secondary slope 20 of the slope toe ditch.
[0060] In this embodiment, the slope chute is used to concentrate the intercepted water at the top of the slope and the drainage from the platform into the drainage ditch at the foot of the slope.
[0061] In this embodiment, horizontal and vertical gravel blind drains are set at the bottom of the fill body where drainage conditions are poor or groundwater is abundant. The vertical blind drain is set inside the fill body, and the horizontal gravel blind drain needs to be set with a certain slope and the slope shall not be less than 0.3%. The surface of the blind drain is wrapped with geotextile.
[0062] In this embodiment, to avoid the adverse effects of groundwater on the stability of the secondary slope 20, inclined drainage pipes and gravel drainage blind ditches below the slope toe should be installed.
[0063] Optionally, after the steps of supporting and / or ecologically restoring the secondary slope 20, the following may also be included: S400: Monitor the secondary slope 20 located at the highest point in each construction section 10.
[0064] By using the above method, deformation signals at the highest point of the secondary slope 20 can be captured, allowing for early identification of potential instability trends and preventing the risk from spreading to the entire construction section 10. Optionally, the step of monitoring the secondary slope 20 located at the highest point in each construction segment 10 specifically includes: monitoring the slope top displacement, slope top movement speed, and slope top movement direction of the secondary slope 20 located at the highest point in each construction segment 10, thereby ensuring the safety of construction.
[0065] Optionally, the steps for monitoring the top displacement, top movement speed, and top movement direction of the secondary slope 20 located at the highest point in each construction section 10 include: setting up observation markers at the top, the ramp, and the toe of the secondary slope 20; and using a total station to observe the observation markers at the top, the ramp, and the toe.
[0066] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
