Abstract
Description
Technical Field
[0001] The present invention relates to the field of landslide prevention and control, and in particular to a comprehensive landslide ecological protection and prevention system and method in arid and cold regions. Background Art
[0002] Water is crucial to the stability of landslides in arid and cold regions. Short-term heavy rainfall in summer causes the moisture content of shallow loess to increase rapidly, resulting in shallow landslides. In winter, snowfall and freeze-thaw effects can also induce deformation and damage of shallow landslides. In addition, melting snow from the mountains continuously replenishes groundwater, causing landslides to be under the action of groundwater for a long time, making them prone to deep deformation.
[0003] Therefore, in arid and cold regions, landslide deformation is the continuous and combined effect of shallow and deep deformation. Furthermore, the ecological environment in arid and cold regions is fragile. Short-term heavy rainfall and freeze-thaw-induced local shallow slip / slip can cause severe soil erosion and damage the ecological environment. Current landslide prevention and control methods essentially focus on the management of deep sliding zones, failing to comprehensively consider the combined deformation of shallow and deep layers. This makes it difficult to guarantee the effectiveness and long-term effectiveness of the management. The ecological environment in arid and cold regions is fragile. Short-term heavy rainfall-induced local slip and shallow sliding can cause soil erosion and damage vegetation roots. At the same time, large deformations can cause deformation and damage to culverts, resulting in ecological and economic losses. Therefore, this paper proposes a comprehensive landslide ecological protection and prevention system and method for arid and cold regions. Summary of the Invention
[0004] The purpose of the present invention is to provide a comprehensive landslide ecological protection system for arid and cold areas, which has a simple structure and can not only dredge the groundwater and surface water of the landslide, but also achieve comprehensive control and reinforcement of shallow and deep sliding bodies, with better effects.
[0005] To achieve the above-mentioned purpose, the present invention discloses a comprehensive landslide ecological protection and prevention system for arid and cold regions, comprising a channel system arranged along the surface of a sliding body, and a plurality of anti-slide piles arranged vertically side by side on the sliding body;
[0006] The channel system includes a plurality of main channel pipelines and branch channel pipelines branching off from each main channel pipeline;
[0007] Multiple main channel pipelines converge into the drainage ditch, and each branch channel pipeline is forked with multiple underground channel pipelines that extend into the slide body and filter and divert water;
[0008] Adjacent anti-slip piles are connected by protective panels with an arch structure. The arc corners of the protective panels face upwards, the arch feet face downwards and the panels are located behind the anti-slip piles.
[0009] Furthermore, the protective panel is provided with a plurality of reinforced tubes containing liquid therein, each reinforced tube is located in the shallow sliding zone and the circumference thereof is filled with crushed stone material with high thermal conductivity.
[0010] Furthermore, the underground channel pipeline includes an outer pipe and an inner pipe which are coaxially arranged and have a flexible structure;
[0011] A filter layer is filled between the outer tube and the inner tube, and water can be drawn in from the outside of the outer tube, filtered through the filter layer, and enter the inner tube.
[0012] Furthermore, the outer tube and the inner tube are flexible metal tubes, and the outer tube is provided with a plurality of first through holes arranged first along its axis and then in the circumferential direction, and the inner tube is provided with a plurality of second through holes arranged first along its axis and then in the circumferential direction;
[0013] The first through holes and the second through holes are staggered with each other.
[0014] Furthermore, the outer tube is a spring structure;
[0015] The inner tube is provided with a plurality of second through holes which are first arranged along the axis and then in the circumferential direction.
[0016] Furthermore, a drainage pipe is provided on the protective panel, and one end of the drainage pipe is connected to the branch channel pipeline.
[0017] The purpose of the present invention is to provide a construction method for a comprehensive landslide ecological protection system in arid and cold areas. The method is simple and effective, and can achieve comprehensive control and reinforcement of shallow and deep sliding bodies with better effects.
[0018] A comprehensive landslide ecological protection and prevention method in arid and cold regions comprises the following steps:
[0019] a. Determine the depth of the shallow sliding zone, deep sliding zone and groundwater level;
[0020] b. Insert the lower ends of multiple parallel anti-slip piles through the deep sliding zone and embed them into the stable stratum to reinforce the deep sliding body; insert the arched protective panel with the arc upward and the arc angle downward through the shallow sliding zone and install it between adjacent anti-slip piles;
[0021] Furthermore, multiple reinforced tubes containing liquid are arranged on the protective panel. The reinforced tubes are located in the shallow sliding zone and are paved with gravel with a high thermal conductivity coefficient on the sides to increase frictional resistance and transfer temperature. The reinforced retaining wall is used to strengthen the shallow sliding body and prevent the shallow sliding from accumulating on the protective panel.
[0022] c. Horizontal or inclined holes are evenly arranged on the landslide, and the inner and outer pipe structures' culverts are inserted into them. Water first enters through the gaps in the outer pipe of the spring structure, then passes through the filter layer to block particles, and finally enters the interior through multiple secondary holes on the inner pipe. This is used to promptly drain groundwater and shallow water caused by short-term heavy rainfall and snowmelt.
[0023] d. Construct multiple branch canal pipelines and main canal pipelines on the slope surface that are connected to the underground canal pipelines in sequence, and divert water from the branch canal pipelines and main canal pipelines to the drainage ditch at the slope corner.
[0024] Compared with the existing technology, this integrated landslide ecological protection and prevention system for arid and cold regions has the following advantages:
[0025] (1) The present invention comprises a channel system comprising a plurality of main channel pipelines and branch channel pipelines branching off from each main channel pipeline. Each branch channel pipeline is provided with a plurality of underground channel pipelines extending into the sliding body and filtering and diverting water, thereby achieving dredging of groundwater and surface water and preventing landslide instability.
[0026] (2) In the present invention, since multiple anti-slip piles are arranged side by side and adjacent anti-slip piles are connected by protective panels with an arched structure, the anti-slip piles are implanted into the landslide to reinforce the deep area, and the protective panels are used to reinforce the shallow sliding caused by short-term rainfall and freeze-thaw, thereby achieving comprehensive control and reinforcement of shallow and deep sliding bodies with better effects. In addition, the arched structure transfers the rear edge thrust caused by the landslide crushing to the protective panel, so that the radial force is converted into the axial force of the anti-slip piles, which significantly changes the force structure of the protective panel, improves the bearing capacity of the protective panel, and can reduce the structural size and reinforcement of the protective panel, thereby reducing costs.
[0027] (3) The present invention provides a plurality of reinforced tubes containing liquid on the protective panel. The reinforced tubes are located in the shallow sliding zone and surrounded by gravel material with high thermal conductivity. Therefore, the reinforced tubes can be used as reinforcement for the reinforced earth retaining wall, interacting with the gravel layer to improve the anti-sliding force, and are suitable for the deformation of the shallow sliding zone. Moreover, the liquid inside the tubes can solidify and liquefy according to the use environment to prevent the soil from freezing.
[0028] (4) Since the culvert pipeline of the present invention includes an outer pipe, an inner pipe and a filter layer therebetween, it provides a sufficient seepage diameter for groundwater filtration and collects the landslide body discharged from the branch pipe. The filter layer is arranged between the inner pipe and the outer pipe, which effectively blocks the soil particles and prevents them from being lost. The outer pipe with a spring structure can adapt to the large shear deformation caused by the uneven deformation of the soil. Without affecting the filtration and drainage, it can effectively withstand the shear of the soil, and the effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0036] The present invention will be further described below with reference to the accompanying drawings.
[0037] like Figure 1 、 Figure 2 As shown, this integrated landslide ecological protection system for arid and cold regions includes a channel system arranged along the surface of a sliding body 14 and a plurality of anti-slide piles 2 arranged vertically side by side on the sliding body 14;
[0038] The channel system includes a plurality of main channel pipelines 41 and branch channel pipelines 42 branching off from each main channel pipeline 41;
[0039] Multiple main channel pipes 41 converge into the drainage ditch 12, and each branch channel pipe 42 is bifurcated with multiple underground channel pipes 5 that extend into the sliding body 14 and filter and divert water;
[0040] Adjacent anti-slip piles 2 are connected by protective panels 3 with an arch structure. The arc corners of the protective panels 3 face upwards, the arch feet face downwards and the panels are located behind the anti-slip piles 2.
[0041] Specifically, in view of the characteristics of arid and cold regions such as short-term heavy rainfall in summer, freeze-thaw in winter and spring, and groundwater recharge from snowmelt in high mountains, the sliding body 14 in the arid and cold regions can be divided into a shallow sliding zone 15 and a deep sliding zone 13. That is, the groundwater in the sliding body 14 receives corresponding water recharge to form a groundwater level 16, forming a shallow area above the landslide body 14 and a deep area deep inside.
[0042] Determine the groundwater conditions in the landslide area and, based on the groundwater level 16 and the corresponding sliding zone location, especially the groundwater outcropping location, set a horizontal drainage ditch 12 at an appropriate location at the bottom of the sliding body 14;
[0043] One end of the culvert pipeline 5 extends deep into the interior of the sliding body 14, and the other end is led out to the surface and connected to the branch pipeline 42, leading the groundwater into the branch pipeline 42, and the branch pipeline 42 then collects the water flow into the main pipeline 41. The water collected by each main pipeline 41 can be led out from the drainage ditch 12 and the drainage channel 11, and the drained groundwater is collected at the slope corners and residential areas for use by people and livestock.
[0044] Anti-slip piles 2 are implanted in the sliding body 14 to reinforce the deep area. Adjacent anti-slip piles 2 are connected to each other by protective panels 3. That is, in the shallow area, protective panels 3 are used to connect the anti-slip piles 2 to form a retaining wall similar to that used to reinforce shallow sliding caused by short-term rainfall and freeze-thaw.
[0045] Short-term heavy rainfall in arid and cold areas will cause local deformation and damage in shallow areas. Accumulation is carried out behind the anti-slip piles 2 to increase the structural stress of the protective panel 3. In addition, local damage will destroy the soil arch effect of the soil behind the piles, so that the force transmitted to the piles by the rear edge thrust gradually decreases, while the force acting on the protective panel 3 increases. The protective panel 3 is subjected to greater pressure and tension and is more prone to damage. Therefore, the protective panel 3 is set to an arch structure. The arch structure can convert radial force into axial force. The anti-slip piles 2 are connected to each other through the arch structure, which can make full use of the characteristics of concrete that is strong in compressive resistance and weak in tensile strength, and convert the nearly horizontal thrust at the rear edge of the landslide into the axial force of the protective panel 3 structure and transmit it to the anti-slip piles 2, significantly improving the structural stress state of the protective panel 3 and saving materials.
[0046] like Figure 3 As shown, the protective panel 3 is provided with a plurality of ribbed tubes 31 containing liquid therein, each ribbed tube 31 is located in the shallow sliding zone 15 and is surrounded by a crushed stone material having a high thermal conductivity.
[0047] Specifically, the liquid-containing reinforced pipe 31 can be used as a reinforcement for a reinforced earth retaining wall. It uses a pipe with high tensile strength and low elongation, such as a PVC reinforcement pipe, and is filled with a liquid, such as water. Not only is the overall flexible structure suitable for deformation of the shallow sliding belt 15, but the liquid inside can solidify and liquefy according to the use environment to prevent the soil from freezing.
[0048] The reinforced tube 31 is located in the shallow sliding zone 13, and an improved gravel material with a high thermal conductivity is provided near the surrounding side. That is, the gravel material forms a gravel layer 32 wrapped around the outside of the reinforced tube 31. The reinforced tube 31 and the gravel layer 32 not only interact with each other to improve the anti-slip force, but also the gravel layer 32 quickly transfers the soil temperature to the reinforced tube 31 in winter, preventing the soil from freezing due to low temperature.
[0049] like Figure 4 、 Figure 5As shown, the underground channel pipeline 5 includes an outer pipe 51 and an inner pipe 54 which are coaxially arranged and have a flexible structure;
[0050] A filter layer 53 is filled between the outer tube 51 and the inner tube 54 , and water can be drawn in from the outside of the outer tube 51 , filtered through the filter layer 53 , and enter the inner tube 54 .
[0051] Specifically, the culvert pipe 5 is a key structure in the channel system. The overall flexible structure has a certain degree of rigidity to prevent the flexible metal pipe from being squeezed and blocked after installation. It can also be adjusted to be flexible and retractable to prevent the culvert pipe 5 from being damaged due to deformation during landslide deformation and severe groundwater fluctuations, which may prevent groundwater from being discharged in time and cause landslide instability.
[0052] As a technical solution, the outer tube 51 and the inner tube 54 are conventional flexible metal tube structures, and the outer tube 51 is provided with a plurality of first through holes 52 arranged first along its axis and then in the circumferential direction, and the inner tube 54 is provided with a plurality of second through holes 55 arranged first along its axis and then in the circumferential direction;
[0053] The first through holes 52 and the second through holes 55 are staggered with each other;
[0054] A first through hole 52 is provided on the outer tube 51, and a second through hole 55 is provided on the inner tube 54, so as to provide a sufficient seepage diameter for groundwater filtration. A filter layer 53 is provided between the inner tube 54 and the outer tube 51 to filter soil particles and prevent the corresponding through holes from being blocked. Groundwater is collected into the branch channel 42 through the two layers of casing and discharged out of the landslide body.
[0055] This structure has great strength and integrity, can resist the deformation of the sliding body 14, and prevent structural damage; at the same time, the structure can be a prefabricated structure, which can be directly inserted into the sliding body 14 through drilling, which is convenient for construction and has a certain guarantee of structural quality.
[0056] like Figure 6 As shown, further, the outer tube 51 is a spring 56 structure;
[0057] The inner tube 54 is provided with a plurality of second through holes 55 arranged first along its axis and then in the circumferential direction;
[0058] That is, the flexible outer tube is made of spring 56, which can adapt to the large shear deformation caused by uneven deformation of the soil. Without affecting filtration and drainage, it can effectively withstand the shear of the soil, resulting in better effect.
[0059] Furthermore, a drainage pipe is provided on the protection panel 3, one end of which is connected to the branch channel 42;
[0060] Therefore, a drainage pipe is provided in the protective panel 3 to promptly discharge the shallow groundwater caused by rainfall and freeze-thaw out of the sliding body 14, thereby reducing the water content of the shallow area and improving the stability of the shallow area.
[0061] This is a comprehensive ecological protection and prevention method for landslides in arid and cold regions. It requires arranging a channel system on the landslide area in the arid and cold region to divert groundwater to a drainage ditch 12. A plurality of anti-slide piles 2 and arched protective panels 3 between adjacent anti-slide piles 2 are arranged on the landslide to effectively reinforce the deep area 13 and the shallow sliding zone 15.
[0062] First, the depths of the shallow sliding zone 15, the deep sliding zone 13, and the groundwater level 16 are determined;
[0063] Then, the lower ends of multiple parallel anti-slip piles 2 are passed through the deep sliding belt 13 and embedded into the stable stratum to reinforce the deep sliding body 13; the protective panel 3 of the arched structure is passed through the shallow sliding belt 13 with the arc angle facing downward and installed between adjacent anti-slip piles 2, and multiple reinforced tubes 31 containing liquid are arranged on the protective panel 3; during construction, backfill soil and crushed stone materials with high thermal conductivity are filled in layers, and the reinforced tubes 31 are arranged in the crushed stone materials, which effectively increases the frictional resistance and transfers the temperature, so that the crushed stone materials and the reinforced tubes 31 form a reinforced retaining wall, which is not only used to reinforce the shallow sliding body 15 and the accumulation of shallow sliding on the protective panel 3, but also effectively prevents the soil from freezing in a low temperature environment and causing shallow sliding;
[0064] Then, horizontal or inclined holes are evenly arranged on the landslide, and a flexible culvert pipe 5 filled with a filter layer 53 is inserted into it. Water first enters through the gaps in the outer pipe 51 of the spring 56 structure, then passes through the filter layer 53 to block the particles, and then enters the interior through multiple second through holes 55 on the inner pipe 54. It is used for culvert drainage, such as spring outcropping points, to promptly drain groundwater and shallow water caused by short-term heavy rainfall and snowmelt, thereby improving the stability of the landslide.
[0065] On the slope surface, build a branch channel pipe 42 and a main channel pipe 5 connected to the underground channel pipe 5 in sequence, so that water flows from the branch channel pipe 42 and the main channel pipe 41 to the drainage ditch 42 at the slope corner;
[0066] Specifically, multiple main channel pipelines 41 are arranged along the slope of the sliding body 14. Each main channel pipeline 41 is provided with multiple branch channel pipelines 42 arranged in a bifurcated manner. Each branch channel pipeline 42 is bifurcated with a culvert pipeline 5 extending deep into the sliding body 14. The channel system is used to dredge groundwater and surface water to prevent landslide instability.
[0067] The culvert pipeline 5 includes an outer pipe 51, an inner pipe 54, and a filter layer 53 located between the outer and inner pipes 51 and 54. Groundwater or surface water can sequentially enter the filter layer 53 through the first through-hole 52 of the outer pipe 51 for filtration, and then enter the inner pipe 54 through the second through-hole 55 for drainage, preventing soil particles from entering the culvert pipeline 5. The first through-hole 52 and the second through-hole 55 are staggered, providing a sufficient seepage path for groundwater filtration. In addition, the culvert pipeline 5 also includes a flexible metal pipe to prevent the culvert pipeline 5 from being damaged or blocked due to extrusion deformation during landslide deformation or severe groundwater fluctuations, thereby preventing groundwater from being discharged in a timely manner.
[0068] Taking into account the shallow and deep deformation, the anti-slip piles 2 are implanted in the landslide and below the deep sliding zone 13 at the lower end to reinforce the deep area; adjacent anti-slip piles 2 are connected to each other by protective panels 3, that is, the shallow sliding zone 15 uses protective panels 3 to connect the anti-slip piles 2 to form a retaining wall similar to that caused by short-term rainfall and freeze-thaw; the arched structure of the protective panel 3 can cause the rear edge thrust caused by the landslide to act on the protective panel 3, so that the radial force is converted into the axial force of the anti-slip pile 2, which significantly changes the force structure of the protective panel 3, improves the bearing capacity of the protective panel 3, and can reduce the structural size and reinforcement of the protective panel 3, thereby reducing costs.
[0069] This is a comprehensive landslide ecological protection and prevention system in arid and cold regions. The construction steps specifically include the following:
[0070] First, the basic conditions of the landslide body are obtained, including the size of the sliding body14, the depth of the sliding zone, rock and soil parameters, groundwater level16 and drainage volume, etc., and regional weather information is collected, such as rainfall data, temperature data, snowfall thickness, etc., to provide basic data for structural design.
[0071] The height of the protective panel 3 and the length of the anti-slip piles 2 are then determined based on the thickness of the shallow sliding zone 15 and the thickness of the deep sliding zone 13, respectively. The limit equilibrium method can be used to calculate the thrust of the sliding body 14 and determine the layout position, cross-sectional dimensions, and spacing of the anti-slip piles 2. In other words, the anti-slip piles 2 are designed and constructed so that they pass through the deep sliding zone 13 and are embedded in the stable stratum to reinforce the deep sliding body.
[0072] Then, a protective panel 3 is designed and constructed, and multiple reinforced tubes 31 are arranged on the protective panel 3. That is, the optimal span of the arched protective panel 3 is calculated based on material mechanics and the maximum thrust of the sliding body 14, and the arch height, cross-sectional dimensions, and reinforcement of the arch structure are obtained. During construction, backfill soil and crushed stone materials with high thermal conductivity are filled in layers, and the reinforced tubes 31 are arranged within the crushed stone materials. This effectively increases frictional resistance and temperature transfer, so that the crushed stone materials and reinforced tubes 31 form a reinforced retaining wall.
[0073] Then, holes are dug on the sliding body 14 for installing the anti-slip piles 2. Concrete is poured into the holes up to the connection with the protective panel 3. Connecting reinforcement is installed at the connection between the anti-slip piles 2 and the protective panel 3. The anti-slip piles 2 and the protective panel 3 are cast as a whole. After the anti-slip piles 2 and the protective panel 3 are solidified, a filter layer is installed at the rear edge of the protective panel 3 and filled and compacted, and a drainage channel is set.
[0074] Finally, a culvert pipeline 5 is set up at the location where surface water is exposed and on the slope by using construction methods such as drilling or open excavation. For example, nearly horizontal / inclined holes are evenly distributed on the slope, and the flexible double-tube structure culvert pipeline 5 is inserted. The outlet end of the culvert pipeline 3 is connected to the main channel pipeline 41 through the branch channel pipeline 42, and the drainage is collected and discharged to the drainage ditch 12 at the foot of the slope.
