[0038] In the related art, slope stability and protection engineering is mainly divided into two types, namely rigid support system and ecological protection technology.

[0039] Among them, the rigid support system includes anti-slide piles, anchor rod frame beams, soil nailing walls and soil retaining structures, etc. These measures provide rigid support force through structural elements such as pile bodies and beam bodies to prevent shear slip of the landslide body.

[0040] However, the traditional anti-slide pile has the defects of large diameter, large excavation amount, long concrete pouring period, and serious damage to the landslide body and vegetation during construction. In addition, after the completion of the construction of the rigid structure, it is difficult for the slope surface to naturally restore vegetation, and the landscape effect is poor, and there is a problem of difficult ecological restoration. Furthermore, most support systems are static structures and cannot monitor or actively respond to the sliding development process, that is, they lack active feedback and adjustment mechanisms.

[0041] In contrast, ecological protection technology is represented by ecological blankets, plant fiber nets, and spray-seeding greening, which can compensate for the ecological shortcomings of rigid support systems by setting up degradable plant substrates, water retention layers, and grass seeds on the slope surface to achieve shallow erosion prevention and surface greening.

[0042] However, the strength of the ecological blanket material is limited and cannot effectively resist the deep shear stress of the landslide body, and it is only suitable for shallow soil protection, and has the problem of insufficient bearing capacity. In addition, under the conditions of heavy rainfall, freezing and thawing, or high temperature and dryness, the ecological blanket is easy to damage or age, and its durability and stability are poor. Furthermore, traditional engineering support focuses on mechanical stability, while ecological protection focuses on surface greening, and the two lack effective coordination, leading to a disconnection between structure and ecology.

[0043] Therefore, there are significant technical contradictions in current slope protection: rigid structures are strong but not green, and ecological protection is green but not strong. How to ensure the stability of the slope structure while achieving ecological restoration and intelligent monitoring has become a key problem that needs to be solved in the field of slope protection.

[0044] Therefore, please refer to Figure 1 The embodiments of the present application provide a slope cooperative reinforcement system for slope 10 protection, especially for landslide treatment. The slope cooperative reinforcement system comprises support piles 100, degradable ecological blankets 200 and biological base connectors 300.

[0045] Among them, a plurality of support piles 100 are provided, and the support piles 100 are inserted into the slope 10. At the same time, the degradable ecological blanket 200 is covered on the slope 10.

[0046] In addition, the biological base connector 300 is provided correspondingly with the support pile 100. The biological base connector 300 is connected with the top of the corresponding support pile 100, and the biological base connector 300 is embedded in the degradable ecological blanket 200.

[0047] In the above-mentioned slope cooperative reinforcement system, a plurality of support piles 100 are inserted into the slope 10 to provide deep anti-sliding support. The degradable ecological blanket 200 is covered on the slope 10 and connected to the top of each support pile 100 through the bio-based connector 300, which can not only provide surface protection but also cooperatively form a composite stable system with the support pile 100 to enhance the reinforcement effect on the slope 10. In addition, the degradable ecological blanket 200 gradually degrades under the action of rainfall and biology, and the degradation product is natural organic matter. After degradation, a porous matrix is formed, which is extremely beneficial to the root development of herbs and shrubs, and ultimately forms a natural anchoring layer composed of plant roots, which can realize the mechanical and ecological transition from artificial structure to natural vegetation, is conducive to the natural recovery of slope 10 vegetation, and effectively improves the problem of difficult ecological recovery of the slope 10.

[0048] It should be noted that there is an ecological slope protection means in the related art that uses a cementing liquid to bond sand and gravel to form a porous solidified layer for plant root growth, but it is essentially a chemical solidification type surface stabilization material. The structure is not degradable, forms a hard shell after solidification, and does not have the ability to change flexibly with vegetation growth, making it difficult to form a natural ecological interface with the support pile 100.

[0049] In contrast, the degradable ecological blanket 200 in the above-mentioned slope cooperative reinforcement system has the characteristic of gradually degrading into a root matrix, and the degradation period is controllable. The natural root anchoring layer formed after the degradation of the degradable ecological blanket 200 has a shear strength superior to that of the artificial solidified layer, and the structural performance is enhanced, which is a "structure gradually replaced by nature" mechanism.

[0050] In addition, the degradable ecological blanket 200 completes the functions of surface scouring and the like during the service period, and then does not leave non-degradable waste, does not form a permanent artificial cover layer, does not hinder the development of plant deep root system, and does not change the natural hydraulic characteristics of the slope 10 soil body, thereby improving the sustainability and life cycle performance of the entire slope 10. That is, the degradation of the degradable ecological blanket 200 realizes seamless switching from artificial materials to natural structures.

[0051] Furthermore, the degradable ecological blanket 200 can gradually become soft over time and naturally integrate with the symbiotic structure of the root system, which can avoid the risk of overall surface slippage caused by high-strength solidified layers, and is more safe and reliable.

[0052] In some embodiments, the degradable ecological blanket 200 is made of mycelium-coconut fiber composite material, forming a multi-layer honeycomb-like breathable structure.

[0053] Among them, the mycelium can degrade in a humid environment within one year, and the degradation period can be controlled within 6-12 months. The mycelium in the degradable ecological blanket 200 is converted into organic matter after degradation and forms a porous root matrix, which is beneficial to promoting the formation of a stable root anchoring layer by plant roots and realizing ecological-mechanical integrated protection.

[0054] In addition, the mycelium naturally has water retention, anti-erosion, organic matter conversion ability, and root germination promotion ability. During the degradation process, the mycelium forms a symbiotic system with the rhizosphere microorganisms, promotes the rhizosphere soil structure granulation, and improves the anti-erosion ability of the slope 10 soil body, having a biological symbiosis-ecological promotion effect.

[0055] Optionally, the content of the mycelium in the degradable ecological blanket 200 is 40%-60%.

[0056] For example, the content of the mycelium can be 40%, 45%, 50%, 55%, 60%, or any value between 40% and 60%.

[0057] For example, the degradable ecological blanket 200 is formed by 3D printing using mycelium-coconut fiber composite materials.

[0058] Further, in some embodiments, the surface of the degradable ecological blanket 200 is provided with a pH-responsive adhesive layer, so that the degradable ecological blanket 200 can adjust the strength automatically.

[0059] Specifically, the pH-responsive adhesive automatically solidifies and enhances in an acidic environment (such as rain), so that the degradable ecological blanket 200 can adapt to the anti-erosion requirements under different climate conditions.

[0060] In some embodiments, the bio-based connector 300 is made of polylactic acid-starch composite material.

[0061] Understandably, the polylactic acid-starch composite material has a certain structural strength, and the bio-based connector 300 made of polylactic acid-starch composite material can be stably connected with the top of the corresponding supporting pile 100. On this basis, the bio-based connector 300 is embedded in the degradable ecological blanket 200, and is limited by the degradable ecological blanket 200, that is, the overall stress cooperation between the degradable ecological blanket 200 and each supporting pile 100 can be realized, a composite stable system is formed, and the reinforcement effect on the slope 10 is enhanced. In this process, the bio-based connector 300 plays a role in structural force transmission.

[0062] In addition, the bio-based connector 300 made of polylactic acid-starch composite material can also be naturally degraded, and does not affect the growth of vegetation after degradation, and has an ecological transition function.

[0063] For example, the bio-based connector 300 is formed by 3D printing using polylactic acid-starch composite materials.

[0064] Further, in some embodiments, the surface of the bio-based connector 300 is provided with a bioactive coating.

[0065] In use, the bioactive coating can promote microbial adhesion and enhance the binding force between the degradable ecological blanket 200 and the ground soil.

[0066] In some embodiments, the support pile 100 comprises a corrugated pipe 110, a filling body 120, and a shape memory alloy ring 130.

[0067] The corrugated pipe 110 is inserted into the slope 10. The filling body 120 is filled in the corrugated pipe 110 to improve the overall shear and uplift resistance. The corrugated pipe 110 and the filling body 120 cooperate to realize the deep anti-slide support function of the foundation, and the surface of the corrugated pipe 110 has multiple grooves to enhance the frictional resistance of the pile-soil interface.

[0068] For example, the filling body 120 uses high-performance cement-based or epoxy mortar.

[0069] In addition, the shape memory alloy ring 130 is arranged on the inner wall of the corrugated pipe 110 along the circumference of the corrugated pipe 110.

[0070] Please refer to Figure 2 Specifically, the shape memory alloy ring 130 has a memory effect. Taking the landslide treatment application scenario as an example, when the landslide body displaces, the deformation of the soil body causes the deformation of the corrugated pipe 110, and the corrugated pipe 110 and the shape memory alloy ring 130 generate friction and heat. After the displacement of the landslide body exceeds a threshold value, the shape memory alloy ring 130 is activated, expands through phase change, and applies pressure to the soil around the pile along the radial direction through the radially freely deformable corrugated pipe 110, forming a circumferential extrusion to the surrounding mortar and soil, enhancing the compactness and frictional resistance of the soil around the pile, and playing a self-compaction-reinforcement role, effectively inhibiting the expansion of the landslide.

[0071] For example, the shape memory alloy ring 130 is locally fixed on the inner wall of the corrugated pipe 110 by a high-temperature-resistant glue. The material of the shape memory alloy ring 130 is a nickel-titanium-based alloy, and the activation temperature is set to trigger the phase change when the horizontal displacement of the landslide body exceeds 5 mm. At this time, the volume of the shape memory alloy ring 130 expands by about 3%-5%.

[0072] In some embodiments, a plurality of shape memory alloy rings 130 are arranged, the axes of the shape memory alloy rings 130 coincide with the axis of the corrugated pipe 110, and the plurality of shape memory alloy rings 130 are arranged along the axis direction of the corrugated pipe 110.

[0073] At this time, the plurality of shape memory alloy rings 130 are uniformly distributed in the corrugated pipe 110, and each shape memory alloy ring 130 can uniformly extrude the surrounding mortar and soil through the corrugated pipe 110, better inhibiting the expansion of the landslide.

[0074] Further, in some embodiments, the support pile 100 is a micro pile.

[0075] Understandably, the micro pile has a small diameter, and is constructed by using a light drilling machine, so that soil disturbance can be reduced.

[0076] In this embodiment, the diameter of the micro pile is 100mm-150mm.

[0077] In some embodiments, a carbon fiber reinforcing rib is further arranged in the corrugated pipe 110, so as to improve the bending and uplift bearing capacity of the micro pile.

[0078] Please refer to Figure 1 and Figure 3 , further, in some embodiments, the above-mentioned slope cooperative reinforcement system further comprises a response unit 400, and the response unit 400 comprises a cable 410.

[0079] The cable 410 is arranged in the degradable ecological blanket 200, the bio-based connecting piece 300 and the filling body 120, and the cable 410 is electrically connected with the shape memory alloy ring 130.

[0080] When it is monitored that the deformation of the landslide body exceeds a threshold value, or the deformation rate or strain of the landslide body is abnormal, the response unit 400 can supply power to the shape memory alloy ring 130 through the cable 410, so as to trigger the shape memory alloy ring 130 to heat and expand. Thus, the response unit 400 and the shape memory alloy ring 130 cooperate, and can actively respond to and inhibit the sliding condition of the landslide body.

[0081] In this embodiment, the cable 410 comprises a main cable 411 and a plurality of branch cables 412. The main cable 411 is arranged in the degradable ecological blanket 200 and the bio-based connecting piece 300. The branch cable 412 is arranged in the bio-based connecting piece 300 and the filling body 120, and the branch cable 412 is electrically connected with the main cable 411 and the shape memory alloy ring 130 respectively.

[0082] Understandably, the branch cable 412 is arranged corresponding to the support pile 100, each branch cable 412 is electrically connected with a plurality of shape memory alloy rings 130 in the corresponding support pile 100 at the same time, and each main cable 411 is electrically connected with a plurality of branch cables 412.

[0083] In this embodiment, the response unit 400 is communicatively connected with a data acquisition and intelligent control module. The data acquisition and intelligent control module acquires a series of data, including but not limited to the displacement of the landslide body, the internal strain of the landslide body, the ground rainfall and the soil pore water pressure, and controls the response unit 400 to supply power to the shape memory alloy ring 130 according to the data.

[0084] For example, when the displacement of the landslide body exceeds the first displacement threshold, the data acquisition and intelligent control module determines that the landslide body is slightly deformed and records it. When the displacement of the landslide body exceeds the second displacement threshold, the data acquisition and intelligent control module determines that the landslide body is severely deformed and controls the response unit 400 to start the shape memory alloy ring 130 response, that is, to power the shape memory alloy ring 130 to make it expand and squeeze the soil around the pile. The second displacement threshold is greater than the first displacement threshold.

[0085] It can be understood that for the case where the displacement of the local area of the landslide body exceeds the second displacement threshold, the data acquisition and intelligent control module only needs to control the response unit 400 to start the shape memory alloy ring 130 response in the corresponding area.

[0086] For example, when the surface rainfall exceeds the first rainfall threshold, the data acquisition and intelligent control module issues a warning. When the surface rainfall exceeds the second rainfall threshold, the data acquisition and intelligent control module determines that the landslide risk is high and controls the response unit 400 to start the local or overall shape memory alloy ring 130 response. The second rainfall threshold is greater than the first rainfall threshold.

[0087] It can be understood that both the surface rainfall and the soil pore water pressure are indirect monitoring methods. When the surface rainfall is too large, landslides are likely to occur, and an increase in soil pore water pressure can directly trigger landslide failure. For landslide monitoring, surface rainfall monitoring and soil pore water pressure monitoring are often more prescient and sensitive than displacement monitoring.

[0088] In some embodiments, the above-mentioned slope cooperative reinforcement system further comprises a monitoring unit 500. The monitoring unit 500 is in communication connection with the response unit 400, and the monitoring unit 500 comprises an optical fiber sensing network, which is arranged in the degradable ecological blanket 200, the bio-based connecting piece 300 and the filling body 120.

[0089] In use, the optical fiber sensing network can detect slope surface strain, slope surface humidity, slope surface pH value, slope surface temperature, slope surface micro-deformation, internal strain of the pile body of the supporting pile 100, internal displacement of the pile body of the supporting pile 100 and other data, providing a basis for the response unit 400 to start the shape memory alloy ring 130 response.

[0090] In this embodiment, the optical fiber sensing network comprises a strain grating and a distributed optical fiber sensor. The type of the optical fiber sensor can be determined according to the measurement object (such as humidity, temperature, etc.).

[0091] In this embodiment, the optical fiber sensing network is in communication connection with the data acquisition and intelligent control module, and transmits the collected data to the data acquisition and intelligent control module for landslide monitoring and stability analysis.

[0092] The monitoring unit 500, the data acquisition and intelligent control module and the response unit 400 cooperate together, and remote monitoring, threshold setting and partition triggering control of the shape memory alloy ring 130 can be realized.

[0093] It should be noted that the cable 410 and the optical fiber sensing network are both pre-embedded in the degradable ecological blanket 200, the bio-based connecting piece 300 and the filling body 120. The internal cable through channel and the optical fiber through channel of the bio-based connecting piece 300 serve as a signal bridging node from deep monitoring to surface monitoring, conduct the strain or displacement signal from the inside of the support pile 100 to the optical fiber sensing network in the degradable ecological blanket 200, so that the deep stress change can be captured by the surface sensing network; and also serve as a triggering node for response feedback, provide a signal return path, ensure the stability of the node, ensure that the signal is reliable and not attenuated, not empty, so that the position of the response unit 400 is coordinated with the monitoring unit 500. Which area is abnormal, triggers the shape memory alloy ring 130 in the corresponding support pile 100.

[0094] Please refer to Figure 3 and Figure 4 The construction process of the above-mentioned slope cooperative reinforcement system is as follows:

[0095] First step, measurement and lofting:

[0096] Determine the laying range of the support pile 100 and the degradable ecological blanket 200 according to the range of the landslide body.

[0097] Second step, hole forming and grouting:

[0098] Small drilling machine is used to form holes, and the hole depth is determined according to the buried depth of the sliding surface, generally 3-8 m. The corrugated pipe 110 is inserted into the hole, and the filling body 120 is poured to form a pile. Each pile is arranged in a quincunx shape in the landslide body.

[0099] Third step, installation of shape memory alloy ring 130:

[0100] The shape memory alloy ring 130 is installed at a predetermined position in the corrugated pipe 110 and connected with the support cable 412 in the response unit 400.

[0101] Fourth step, laying of degradable ecological blanket 200:

[0102] Lay the degradable ecological blanket 200 on the slope surface, so that the degradable ecological blanket 200 and the top of each support pile 100 are firmly connected through the bio-based connecting piece 300.

[0103] Fifth step, laying of monitoring network:

[0104] Install the optical fiber sensing network and connect the signal line to the monitoring host. The monitoring host can be the data acquisition and intelligent control module.

[0105] Sixth step, system debugging:

[0106] After the test of sensing, signal transmission and shape memory alloy ring 130 activation, the closed-loop system is confirmed to be in normal operation and put into use.

[0107] In summary, in the above-mentioned slope cooperative reinforcement system, a plurality of support piles 100 are inserted into the slope 10 to provide deep anti-slide support. The degradable ecological blanket 200 is covered on the slope 10 and connected to the top of each support pile 100 through the bio-based connector 300, which can not only provide surface protection but also cooperatively form a composite stable system with the support pile 100 to enhance the reinforcement effect on the slope 10. In addition, the degradable ecological blanket 200 gradually degrades under the action of rainfall and biology, and the degradation product is natural organic matter. After degradation, a porous matrix is formed, which is extremely beneficial to the root development of herbs and shrubs, and ultimately forms a natural anchoring layer composed of plant roots, which can realize the mechanical and ecological transition from artificial structure to natural vegetation, and is conducive to the natural recovery of the slope 10 vegetation, effectively improving the problem of difficult ecological recovery of the slope 10.

[0108] Among them, the support pile 100 adopts a micro pile, which can realize low disturbance and rapid construction of the soil body. The response unit 400 cooperates with the monitoring unit 500, so that the shape memory alloy ring 130 can be automatically activated when the landslide body slips out of limit, forming a self-sensing-self-reinforcing closed loop. In addition, the monitoring unit 500 also has long-term monitoring capability, which can realize long-term monitoring and remote early warning of landslide body deformation, humidity and acid-base environment.

[0109] The above-mentioned slope cooperative reinforcement system integrates the functions of structural reinforcement, ecological restoration and intelligent monitoring, and has the advantages of short construction period, small disturbance, strong sustainability and long-term self-repairing capability. It is suitable for protection and reinforcement engineering of complex geological environment such as landslide, dangerous rock and highway and railway slope, and can significantly improve the stability and ecological coordination of the slope 10.

[0110] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combination of these technical features does not exist contradictory, it should be considered as the scope of the description.

[0111] The above-mentioned embodiments only express several implementation ways of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
