A reinforcement device for high and steep slopes

Abstract

The present invention provides a reinforcement device for high and steep slopes. By setting a growing tube, a water-isolating tube and an outer tube, and setting a first induction matrix and a second induction matrix with different concentrations of effective ingredients in the growing tube and between the growing tube and the outer tube, the root system of the fixed green plants is induced to grow along the axial direction of the growing tube first to penetrate into the interior of the slope, and then to develop along the radial direction of the growing tube to fix the soil in a larger range. At the same time, a cutting component is arranged on the periphery of the growing tube to facilitate the removal of withered fixed green plants. On the one hand, the roots of the fixed green plants are used to reinforce the slope, and on the other hand, the transpiration of the fixed green plants is used to dissipate moisture in the soil into the atmosphere, thereby reducing soil deformation and flow and improving the stability of the slope. Since the soil is fixed and modified mainly by the roots of the fixed green plants, the reinforcement device of the present invention can not only better reinforce the slope, but also have a positive impact on the ecological environment.

Description

Technical Field

[0001] The invention relates to the field of geotechnical engineering, and in particular to a reinforcement device for high and steep slopes. Background Art

[0002] Soil nailing is often used to reinforce high and steep slopes, especially those made of soil or soft rock. This technology is widely favored for its advantages of simple and fast construction and relatively economical cost. However, when faced with complex geological conditions such as deep soft soil layers, the soil is prone to deformation and flow when subjected to stress because the soil usually has the characteristics of high water content, high porosity and low shear strength, which reduces the adhesion and friction between the soil nails and the soil, making the effect of soil nailing reinforcement often unsatisfactory. At this time, it is usually necessary to combine other reinforcement methods, such as foundation replacement method or deep mixing method, to jointly improve the stability of the slope. These auxiliary reinforcement methods usually require a certain degree of soil treatment to change its original properties, which will have a greater adverse impact on the local soil structure and ecological environment. Summary of the invention

[0003] The reinforcement device for high and steep slopes of the present invention optimizes the problem that the reinforcement method for slopes in the prior art has an adverse effect on the ecological environment, and can have a positive impact on the ecological environment.

[0004] To achieve the above object, the present invention provides a reinforcement device for high and steep slopes, comprising:

[0005] An induction tube, the induction tube comprising a growth tube, a water-blocking tube and an outer tube, the growth tube extending from the slope surface to the inside of the slope, the water-blocking tube detachably connected to one end of the growth tube away from the slope surface and connected to the growth tube; the outer tube is sleeved on the outside of the growth tube, the outer tube is provided with a through hole, the through hole passes through from the outer tube to the growth tube, and the through hole of the growth tube is blocked by a degradable material;

[0006] A first induction matrix, wherein the first induction matrix is ​​arranged inside the growth tube;

[0007] A second induction matrix, wherein the second induction matrix is ​​disposed between the outer tube and the growth tube, and the effective component of the second induction matrix is ​​higher than that of the first induction matrix;

[0008] A cutting component, the cutting component is arranged on the outer periphery of the growing tube, the cutting component comprises a cutting tool, and the cutting tool is slidably arranged on the outer side of the growing tube;

[0009] The effective ingredients here refer to hormones such as fertilizers or rooting agents. The reinforcement device of the present invention is mainly used for slopes with deep soft soil layers. When in use, the fixed green plants are planted on the first induction matrix, and the roots of the fixed green plants are inside the growth tube. In the initial stage, the root system of the fixed green plants is restricted by the inner wall of the growth tube and the induction effect of the first induction matrix, and the concentration of the effective ingredients of the second induction matrix is ​​greater than that of the first induction matrix. At this time, the second induction matrix will inhibit the growth of the fixed green plants therein, so the roots of the fixed green plants will develop along the growth tube to the inside of the slope, thereby being deeply implanted in the soil. In addition, since the through hole of the growth tube is blocked by degradable materials, the effective ingredients of the second induction matrix are difficult to diffuse into the inside of the growth tube, which affects the growth of the roots of the fixed green plants at this stage.

[0010] In the second stage, the effective ingredients of the second induction matrix will diffuse into the soil around the reinforcement device through the through holes, so that the concentration of the ingredients in the second induction matrix and the surrounding area is reduced to a suitable range for the growth of the root system of the fixed green plants, which is beneficial for the roots of the fixed green plants at this stage to extend laterally to a wider range, thereby fixing more soil. At the same time, the fixed green plants can also absorb moisture from the soil through their roots, and dissipate the moisture into the atmosphere through transpiration, thereby reducing the water content and pore water pressure of the soil. It helps to reduce soil deformation and flow and improve the stability of the slope. Since the reinforcement device of the present invention mainly fixes and modifies the soil through the roots of fixed green plants, it can have a positive impact on the ecological environment.

[0011] Since the reinforcement device of the present invention is mainly used for slopes with thick soft soil layers and high soil moisture content, moisture can easily penetrate into the growth tube, reducing the air permeability in the growth tube and adversely affecting the growth of the roots of the fixed green plants. The provision of the waterproof tube can discharge excess moisture in the growth tube, improve the air permeability in the growth tube, and be beneficial to the growth of the roots of the fixed green plants.

[0012] After the fixed green plants wither, the reinforcement effect on the slope will decrease, because the roots of the fixed green plants have grown into the soil of the slope, and it is difficult to replace the fixed green plants. The cutting component can cut off the roots of the fixed green plants along the outer contour of the growing tube. At this time, the growing tube connected to the withered fixed green plants can be removed from the watertight tube, and the growing tube planted with new fixed green plants can be installed on the watertight tube. It can be seen that the reinforcement device of the present invention has high maintenance convenience.

[0013] As an optional technical solution, it also includes a guide cone arranged inside the growing tube, the guide cone is arranged at the end where the growing tube is connected to the water-blocking tube, the bottom of the guide cone is connected to the inner wall of the growing tube, the tip of the guide cone faces the slope, and the top of the guide cone is provided with a plurality of connecting holes along the direction from the tip of the guide cone to the bottom of the guide cone; the outer wall of the growing tube is partially hollowed out corresponding to the bottom of the guide cone. The end of the root of the fixed green plant is highly active, and after reaching the end of the growing tube, it is affected by the guide cone and grows along its surface until it reaches the bottom of the guide cone, and extends from the outer wall of the growing tube to the outside of the growing tube.

[0014] As an optional technical solution, the cutting tool is annular and sleeved on the outside of the growing tube, and the cutting tool blade faces the slope surface and / or the inside of the slope;

[0015] The cutting component also includes a connecting portion, which is connected to the cutting tool and extends from the cutting tool to the end of the growing tube close to the slope. If the fixed green plant withers and dies during the use of the fixing device, the cutting tool can be slid axially along the growing tube through the connecting portion to cut off the root system of the fixed green plant extending into the slope soil, making it easier to replace the growing tube and fix the green plant.

[0016] As an optional technical solution, the cutting component further includes a retaining frame, the retaining frame is rotatably connected to the growing tube, the cutting tool is axially connected to the retaining frame along the growing tube and extends between the outer tube and the growing tube, and the blade of the cutting tool faces the circumference of the growing tube and is arranged corresponding to the through hole of the growing tube. If the fixed green plant withers and dies during the use of the fixing device, the cutting tool can be slid along the circumference of the growing tube by rotating the retaining frame, thereby cutting off the root system of the fixed green plant extending into the slope soil, making it easier to replace the growing tube and fix the green plant.

[0017] As an optional technical solution, the retaining frame is sleeved on the outside of the growing tube, and gear teeth are respectively provided on the inside of the retaining frame and on the outside of the growing tube and the corresponding positions of the retaining frame; the cutting component also includes a driving gear, which is provided between the growing tube and the retaining frame and meshes with the gear teeth on the outside of the growing tube and the retaining frame. By rotating the driving gear, the retaining frame and the growing tube can rotate relative to each other, so that the cutting tool cuts off the extended root system of the fixed green plant.

[0018] As an optional embodiment, the cutting component further includes a drive shaft, which is connected to the drive gear and is used to connect to a drive device. The root system of the fixed green plant may be relatively tough and strong, and the soil will also produce resistance to the cutting tool, which makes it difficult for the cutting tool to cut the root system. By setting the drive shaft, a drive device capable of outputting a large torque can drive the drive gear, thereby completing the cutting of the root system.

[0019] As an optional technical solution, the high and steep slope includes underground drainage facilities, and the waterproof tube is connected to the underground drainage facilities. As mentioned above, the waterproof tube can collect excess moisture in the growth tube. The waterproof tube is connected to the underground drainage facilities and can discharge the collected moisture from the underground drainage facilities, thereby improving the air permeability inside the fixing device and providing favorable conditions for the growth of the roots of the fixed green plants.

[0020] As an optional technical solution, it also includes a retaining ring, which is arranged at the end of the outer tube close to the watertight tube. The retaining ring helps to prevent the second inducing matrix in the outer tube from leaking from the bottom of the outer tube when the reinforcement device is installed.

[0021] As an optional technical solution, the outer tube is made of a degradable material. When the roots of the fixed green plants extend to the inside of the outer tube, the outer tube is partially or completely degraded, making room for the growth of the roots, thereby preventing the outer tube from limiting the growth range of the roots and facilitating the roots to fix a larger range of soil.

[0022] As an optional technical solution, the bottom of the watertight tube is conical, which helps to reduce the resistance when the reinforcement device is installed.

[0023] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0024] The reinforcement device for high and steep slopes of the present invention is provided with a growing tube, a water-isolating tube and an outer tube, and a first induction matrix and a second induction matrix with different concentrations of effective ingredients are provided inside the growing tube and between the growing tube and the outer tube, so as to induce the root system of the fixed green plants to first grow along the axial direction of the growing tube to penetrate into the interior of the slope, and then develop along the radial direction of the growing tube to fix the soil in a larger range, and at the same time, a cutting component is provided on the periphery of the growing tube to facilitate the removal of withered fixed green plants. On the one hand, the roots of the fixed green plants are used to reinforce the slope, and on the other hand, the transpiration of the fixed green plants is used to dissipate the moisture in the soil into the atmosphere, thereby reducing the deformation and flow of the soil and improving the stability of the slope. Since the soil is fixed and modified mainly by the roots of the fixed green plants, the reinforcement device of the present invention can not only better reinforce the slope, but also have a positive impact on the ecological environment.

[0045] Soil nailing is often used to reinforce high and steep slopes, especially those made of soil or soft rock. This technology is widely favored for its advantages of simple and fast construction and relatively economical cost. However, when faced with complex geological conditions such as deep soft soil layers, the soil is prone to deformation and flow when subjected to stress because the soil usually has the characteristics of high water content, high porosity and low shear strength, which reduces the adhesion and friction between the soil nails and the soil, making the effect of soil nailing reinforcement often unsatisfactory. At this time, it is usually necessary to combine other reinforcement methods, such as foundation replacement method or deep mixing method, to jointly improve the stability of the slope. These auxiliary reinforcement methods usually require a certain degree of soil treatment to change its original properties, which will have a greater adverse impact on the local soil structure and ecological environment.

[0046] In addition, planting fixed green plants on the slope is also a common auxiliary reinforcement method, but the fixing effect on deep soft soil layers is not good. The soil strength of soft soil layers is usually low, which means that the bonding force between soil particles is weak and the soil is easily deformed under external forces. This low-strength soil environment is not conducive to the anchoring and growth of plant roots, because the root system needs a stable soil environment to provide support and nutrients. The stability of soft soil layers is also poor, and it is prone to settlement and sliding. This unstable soil environment will cause additional pressure and interference on plant roots during growth, thus affecting their normal growth and expansion. Soft soil layers usually contain high moisture, which will lead to a decrease in the oxygen content in the soil and affect the respiration of plant roots. At the same time, high water content will also make the soil soft and deformable, further exacerbating the difficulty of root growth. The nutrient content in soft soil layers is often low, lacking the necessary elements required for plant root growth. This will cause the plant roots to face the problem of insufficient nutrients during growth, thus affecting their growth rate and expansion ability. The growth of plant roots requires a stable soil environment and sufficient nutrient support. In soft soil layers, due to the existence of the above-mentioned unfavorable factors, it is often difficult for the roots to form a stable growth environment, resulting in restricted root growth and poor slope reinforcement effect of plants.

[0047] Based on this, the present invention provides a reinforcement device for high and steep slopes, which is provided with a growing tube, a water-isolating tube and an outer tube, and a first induction matrix and a second induction matrix with different concentrations of effective ingredients are provided inside the growing tube and between the growing tube and the outer tube, so as to induce the root system of the fixed green plants to grow along the axial direction of the growing tube first to penetrate into the interior of the slope, and then to develop along the radial direction of the growing tube to fix the soil in a larger range, and at the same time, a cutting component is provided on the periphery of the growing tube to facilitate the removal of withered fixed green plants. On the one hand, the roots of the fixed green plants are used to reinforce the slope, and on the other hand, the transpiration of the fixed green plants is used to dissipate the moisture in the soil into the atmosphere, thereby reducing the deformation and flow of the soil and improving the stability of the slope. Since the soil is fixed and modified mainly by the roots of the fixed green plants, the reinforcement device of the present invention can not only better reinforce the slope, but also have a positive impact on the ecological environment.

[0048] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings. Example 1

[0049] This embodiment provides a reinforcement device 100 for a high and steep slope. The present invention provides a reinforcement device 100 for a high and steep slope, comprising:

[0050] The induction tube includes a growth tube 1, a watertight tube 2 and an outer tube 3. The growth tube 1 extends from the slope surface of the slope 200 to the inside of the slope 200. The watertight tube 2 is detachably connected to the end of the growth tube 1 away from the slope surface and is connected to the growth tube 1. The outer tube 3 is sleeved on the outside of the growth tube 1. The outer tube 3 is provided with a through hole 11. The through hole 11 passes through the outer tube 3 to the growth tube 1. The through hole 11 of the growth tube 1 is blocked by a degradable material.

[0051] A first induction matrix 4, which is arranged inside the growth tube 1;

[0052] A second induction matrix 5, which is disposed between the outer tube 3 and the growth tube 1, and the effective components of the second induction matrix 5 are higher than those of the first induction matrix 4;

[0053] A cutting component 6, which is arranged on the outer periphery of the growing tube 1. The cutting component 6 comprises a cutting tool 61, which is slidably arranged on the outer side of the growing tube 1;

[0054] The reinforcement device 100 of the present invention is mainly used for the slope 200 with a thick soft soil layer 300. When in use, the fixed green plant 202 is planted on the first induction matrix 4, and the root of the fixed green plant 202 is inside the growth tube 1. In the initial stage, the root system of the fixed green plant 202 is restricted by the inner wall of the growth tube 1 and the induction effect of the first induction matrix 4, and the concentration of the effective component of the second induction matrix 5 is greater than that of the first induction matrix 4, so that the second induction matrix 5 will inhibit the growth of the fixed green plant 202 therein, and the root system of the fixed green plant 202 will develop along the growth tube 1 to the inside of the slope 200, thereby being deeply implanted in the soil. In addition, since the through hole 11 of the growth tube 1 is blocked by a degradable material, the effective component of the second induction matrix 5 is difficult to diffuse into the inside of the growth tube 1, which affects the growth of the root system of the fixed green plant 202 at this stage.

[0055] In the second stage, the degradable material is degraded, and the effective ingredients of the second induction matrix 5 will diffuse into the soil around the reinforcement device 100 through the through hole 11, so that the concentration of the ingredients in the second induction matrix 5 and the surrounding area is reduced to a suitable range for the growth of the root system of the fixed green plants 202, which is beneficial for the roots of the fixed green plants 202 to extend laterally to a wider range at this stage, thereby fixing more soil. At the same time, the fixed green plants 202 can also absorb moisture from the soil through the root system, and dissipate the moisture into the atmosphere through transpiration, thereby reducing the water content and pore water pressure of the soil. It helps to reduce soil deformation and flow and improve the stability of the slope 200. Since the reinforcement device 100 of the present invention mainly fixes and modifies the soil by fixing the roots of the green plants 202, it can have a positive impact on the ecological environment.

[0056] Since the reinforcement device 100 of the present invention is mainly used in the slope 200 with a thick soft soil layer 300, the soil moisture content is relatively high, and the moisture can easily penetrate into the growth tube 1, reducing the air permeability in the growth tube 1, and having an adverse effect on the growth of the roots of the fixed green plants 202. The provision of a waterproof tube 2 can discharge excess moisture in the growth tube 1, improve the air permeability in the growth tube 1, and facilitate the growth of the roots of the fixed green plants 202.

[0057] After the fixed green plants 202 wither, the reinforcement effect on the slope 200 will decrease. Since the roots of the fixed green plants 202 have grown into the soil of the slope 200, it is difficult to replace the fixed green plants 202. The cutting component 6 can cut off the roots of the fixed green plants 202 along the outer contour of the growing tube 1. At this time, the growing tube 1 connected to the withered fixed green plants 202 can be removed from the water-isolating tube 2, and the growing tube 1 planted with new fixed green plants 202 can be installed on the water-isolating tube 2. It can be seen that the reinforcement device 100 of the present invention has high maintenance convenience.

[0058] The growing tube 1 is detachably connected to the waterproof tube 2. As mentioned above, the waterproof tube 2 needs to penetrate the deep soft soil layer 300. The detachable connection between the growing tube 1 and the waterproof tube 2 allows the growing tube 1 to be connected to waterproof tubes 2 of different lengths, so as to cope with deep soft soil layers 300 of different thicknesses, which is conducive to improving the flexibility of the reinforcement device 100 in the present invention. In some embodiments, the waterproof tube 2 can penetrate into and communicate with areas such as soil layers or rock layers with low water content, and discharge the water collected from the growing tube 1.

[0059] It should be noted that the fixed green plants 202 should be selected from deep-rooted slope protection plants that are more tolerant to a wet environment, such as Pennisetum, Pampas grass, and Amorpha fruticosa, etc., which are not limited in this embodiment.

[0060] It should be noted that the effective ingredients of the first induction matrix 4 and the second induction matrix 5 refer to mineral nutrient matrices such as nitrogen, phosphorus, potassium, etc., organic matter matrices such as humic acid, hormone matrices such as rooting agents, and microbial matrices such as nitrogen-fixing bacteria. The first induction matrix 4 and the second induction matrix 5 are made of the above-mentioned effective ingredients mixed with soil with good air permeability. In practice, the appropriate ratio should be selected according to factors such as the specific variety of the fixed green plants 202, and this embodiment is not limited here.

[0061] Exemplarily, the degradable material may be polylactic acid, starch plastic or paper material, etc. Example 2

[0062] On the basis of Example 1, the reinforcement device 100 further includes a guide cone 12 disposed inside the growing tube 1, the guide cone 12 is disposed at the end where the growing tube 1 is connected to the water-blocking tube 2, the bottom of the guide cone 12 is connected to the inner wall of the growing tube 1, the tip of the guide cone 12 faces the slope, and the top of the guide cone 12 is provided with a plurality of connecting holes 121 in the direction from the tip of the guide cone 12 to the bottom of the guide cone 12; the outer wall of the growing tube 1 is partially hollowed out corresponding to the bottom of the guide cone 12. The end of the root of the fixed green plant 202 is highly active, and after reaching the end of the growing tube 1, it is affected by the guide cone 12 to grow along its surface until it reaches the bottom of the guide cone 12, and extends from the outer wall of the growing tube 1 to the outside of the growing tube 1.

[0063] As an optional embodiment, the growing tube 1 is detachably connected to the waterproof tube 2. As mentioned above, the waterproof tube 2 needs to penetrate the deep soft soil layer 300. The detachable connection between the growing tube 1 and the waterproof tube 2 allows the growing tube 1 to be connected to waterproof tubes 2 of different lengths, so as to cope with deep soft soil layers 300 of different thicknesses, which is conducive to improving the flexibility of the reinforcement device 100 in the present invention. In some embodiments, the waterproof tube 2 can penetrate into and communicate with areas such as soil layers or rock layers with low water content, and discharge the water collected from the growing tube 1.

[0064] Furthermore, the high and steep slope 200 includes an underground drainage facility 201, and the watertight tube 2 is connected to the underground drainage facility 201. As mentioned above, the watertight tube 2 can collect excess water in the growth tube 1. The watertight tube 2 is connected to the underground drainage facility 201, and the collected water can be discharged from the underground drainage facility 201, thereby improving the air permeability inside the fixing device and providing favorable conditions for the growth of the roots of the fixed green plants 202. In addition, when the conditions for connecting the watertight tube 2 to the underground drainage facility 201 are not met, the watertight tube 2 can also penetrate the soft soil layer 300 to reach other geological layers with lower water content and discharge excess water.

[0065] As an optional technical solution, the cutting tool 61 is annular and sleeved on the outside of the growing tube 1, and the cutting tool 61 is facing the slope and / or the inside of the slope 200;

[0066] The cutting member 6 also includes a connection portion 65, which is connected to the cutting tool 61 and extends from the cutting tool 61 to the end of the growing tube 1 close to the slope. If the fixed green plant 202 withers and dies during the use of the fixing device, the cutting tool 61 can be slid axially along the growing tube 1 through the connection portion 65 to cut off the root system of the fixed green plant 202 extending into the soil of the slope 200, making it easier to replace the growing tube 1 and fix the green plant 202.

[0067] As an optional embodiment, the growing tube 1 is threadedly connected to the watertight tube 2, and the reinforcement device 100 also includes a cutting component 6, which includes a retaining frame 62 and a cutting tool 61. The retaining frame 62 is rotatably connected to the growing tube 1, and the cutting tool 61 is axially connected to the retaining frame 62 along the growing tube 1 and extends between the outer tube 3 and the growing tube 1. The blade of the cutting tool 61 is arranged corresponding to the through hole 11 of the growing tube 1. The fixed green plant 202 may wither and die during the use of the fixing device, affecting the fixing effect on the soil. At this time, the growing tube 1 is rotated to separate the growing tube 1 from the watertight tube 2. At this time, the root system of the withered fixed green plant 202 rotates with the growing tube 1, and the cutting component 6 is fixed, so that the cutting tool 61 cuts off the root system, and then the growing tube 1 and the cutting component 6 are taken out from the inside of the slope 200 together, and the growing tube 1 with a new fixed green plant 202 is replaced, which is conducive to improving the convenience of maintenance of the reinforcement device 100.

[0068] As an optional embodiment, a retaining ring 31 is further included. The retaining ring 31 is arranged at the end of the outer tube 3 close to the watertight tube 2. The retaining ring 31 helps to prevent the second inducing matrix 5 in the outer tube 3 from leaking from the bottom of the outer tube 3 when the reinforcement device 100 is installed.

[0069] As an optional embodiment, the material of the outer tube 3 is a degradable material. When the roots of the fixed green plants 202 extend to the inside of the outer tube 3, the outer tube 3 is partially or completely degraded, which can make room for the growth of the roots, avoid the outer tube 3 limiting the growth range of the roots, and help the roots fix the soil in a larger range.

[0070] As an optional embodiment, the bottom of the watertight tube 2 is tapered. The tapered bottom of the watertight tube 2 helps to reduce the resistance when the reinforcement device 100 is installed. Example 3

[0071] On the basis of Example 1, the cutting component 6 further includes a holder 62, the holder 62 is rotatably connected to the growing tube 1, the cutting tool 61 is axially connected to the holder 62 along the growing tube 1 and extends between the outer tube 3 and the growing tube 1, and the blade of the cutting tool 61 faces the circumference of the growing tube 1 and is arranged corresponding to the through hole 11 of the growing tube 1. If the fixed green plant 202 withers and dies during the use of the fixing device, the cutting tool 61 is slid along the circumference of the growing tube 1 by rotating the holder 62, thereby cutting off the root system of the fixed green plant 202 extending into the soil of the slope 200, which is convenient for replacing the growing tube 1 and fixing the green plant 202.

[0072] As an optional technical solution, the holder 62 is sleeved on the outside of the growing tube 1, and gear teeth are respectively provided on the inside of the holder 62 and the corresponding positions of the outside of the growing tube 1 and the holder 62; the cutting component 6 also includes a driving gear 63, which is arranged between the growing tube 1 and the holder 62 and meshes with the gear teeth on the outside of the growing tube 1 and the holder 62. By rotating the driving gear 63, the holder 62 and the growing tube 1 can be rotated relative to each other, so that the cutting tool 61 cuts off the extended root system of the fixed green plant 202.

[0073] In addition, a plurality of support gears 631 may be arranged between the retaining frame 62 and the growth tube 1. The support gears 631 and the driving gears 63 are arranged at intervals along the circumference of the growth tube, so that the retaining frame 62 and the growth tube 1 remain coaxial during relative rotation under the action of the driving gear 63, which is beneficial to maintaining the cutting effect of the cutting tool 61.

[0074] As an optional embodiment, the cutting component 6 further includes a driving shaft 64, which is connected to the driving gear 63, and the driving shaft 64 is used to connect the driving device. The root system of the fixed green plant 202 may be relatively tough and strong, and the soil will also produce resistance to the cutting tool 61, which makes it difficult for the cutting tool 61 to cut the root system. By providing the driving shaft 64, the driving device that can output a large torque can drive the driving gear 63, thereby completing the cutting of the root system.

[0075] The driving device may be any type of motor, and may include a transmission mechanism such as a reducer. The driving shaft 64 and the driving gear 63 may be connected by a flat key or a spline to form a split structure, or the driving gear 63 may be formed on the driving shaft 64, so that the driving shaft 64 is an integrated structure of a gear shaft.
