Description

Technical Field

[0001] The invention belongs to the technical field of greening protection devices, and in particular relates to a greening protection device for railway civil engineering. Background Art

[0002] In the field of civil engineering, railway construction inevitably involves large-scale manual excavation, which directly leads to the formation of numerous slopes. If these slopes are not properly protected and greened, they often cause a series of environmental problems. Specifically, they not only lead to the widespread emergence of secondary bare land, exposing land previously covered with vegetation, but also exacerbate soil erosion and further deteriorate the ecological environment. More seriously, these slopes can become the source of potential shallow landslides, posing a significant threat to the safe operation of railways.

[0003] Traditionally, slope protection in construction projects has been achieved by covering the slope surface with hard materials such as stone, concrete, and blocks. While this method can strengthen the shallow structure of the slope and improve its stability to a certain extent, it inevitably deprives vegetation of the natural environment necessary for growth, resulting in severe damage to the original ecological landscape and its gradual disappearance.

[0004] To improve the ecological environment along railway lines and effectively curb soil erosion, many regions have planned green belts along the railway lines, planting appropriate vegetation to beautify the landscape and restore ecological functions. However, these green belts, particularly those located on slopes, face severe challenges from rainwater erosion. Due to the lack of necessary protective structures on the slopes, the rock and soil are easily eroded by rainwater, making it difficult for plant roots to stabilize, thus threatening the overall stability of the slopes and the durability of the greening effect.

[0005] Therefore, whether or not an objective environment suitable for plant growth can be effectively provided is the key to the success of slope greening. Currently, the greening methods for rock slopes mainly include spray-mixed vegetation technology, organic substrate spraying, cement ecological planting base, and vegetation concrete slope protection and greening technology. Although these technologies have different names, their core principle is to use sprayed concrete soil consolidation technology. However, due to the large slope angle, the sprayed plants are often difficult to fix on such rock slopes. Even if some plants can be fixed, they will find it difficult to survive due to the poor soil and water retention of the rock slopes. As a result, existing greening methods still face many challenges in practical application.

[0006] In view of the above problems, we urgently need a railway civil engineering greening protection device to scientifically and rationally solve the dual challenges faced by slope protection and greening. Summary of the Invention

[0007] In order to solve the technical problems existing in the above-mentioned prior art, the present invention proposes a railway civil engineering greening protection device, which aims to protect the stability of the slope and promote vegetation growth, thereby achieving harmonious coexistence of the ecological environment along the railway.

[0008] The technical solution adopted in the present invention is as follows:

[0009] A railway civil engineering greening protection device includes a slope rock mass, a water storage ditch arranged at the top of the slope rock mass, and a retaining wall and a drainage ditch arranged at the foot of the slope rock mass. Anchor rods are provided in the slope rock mass, and a grid beam and a drainage facility are provided on the slope surface of the slope rock mass. Green plants are planted in the grid beam. The drainage facility includes a drainage ditch and a drainage trough assembly. The drainage ditch is arranged along the slope surface of the slope rock mass, and the tail end of the drainage ditch can guide water to the drainage ditch. The drainage trough assembly is arranged on the grid beam and can guide water in the grid beam to the drainage ditch. A plurality of drip irrigation pipes are connected below the water storage ditch. The drip irrigation pipes are buried in the slope rock mass and located below the green plants. A plurality of drip irrigation holes are opened below the drip irrigation pipes.

[0010] In a further technical solution, the slope rock mass is formed by a continuous arrangement of high and steep slope sections and gentle slope sections, and grid beams are provided on both the high and steep slope sections and the gentle slope sections, and climbing vegetation and / or hanging vegetation as well as mixed vegetation of trees, shrubs and grasses are planted in the grid beams of the gentle slope sections.

[0011] In a further technical solution, a slope protection component and a vegetation bag are provided in the grid beam of the steep slope section. The slope protection component includes a metal mesh and a flexible protective net. The metal mesh and the flexible protective net are sequentially covered on the slope surface of the steep slope section. The vegetation bag is tied to the metal mesh, and the flexible protective net covers the outside of the vegetation bag.

[0012] In a further technical solution, the grid beam includes multiple longitudinal characteristic beams and multiple transverse characteristic beams, the longitudinal characteristic beams and transverse characteristic beams are vertically connected, and the longitudinal characteristic beams of the upper and lower adjacent layers of the grid beams in the steep slope section are staggered to form a mesh structure.

[0013] In a further technical solution, the drain trough assembly includes a longitudinal drain trough, a first transverse inclined drain trough, a second transverse inclined drain trough and a total drain trough. The longitudinal drain trough is vertically arranged on the longitudinal characteristic beam. The first transverse inclined drain trough and the second transverse inclined drain trough are both vertically arranged on the transverse characteristic beam and are respectively located on both sides of the longitudinal drain trough. The water retained by the upper longitudinal drain trough can be guided into the lower longitudinal drain trough. The total drain trough is installed in the gentle slope section and is located below the water outlet of the corresponding longitudinal drain trough. It is used to receive the water retained by the longitudinal drain trough and guide the water into the drainage ditch.

[0014] In a further technical solution, the first transverse inclined drain trough and the second transverse inclined drain trough are both L-shaped and are inclined toward one side of the lower longitudinal drain trough.

[0015] In a further technical solution, a drainage pipe is connected to the upper side wall of the water storage ditch, and the drainage pipe extends through the slope rock mass and is connected to the drainage ditch.

[0016] In a further technical solution, a water supply pipe is provided at the bottom of the water storage ditch, the diameter of the water supply pipe is smaller than that of the drip irrigation pipe, and the water supply pipe is connected to the drip irrigation pipe. A water stop plug with a diameter larger than that of the water supply pipe is provided in the drip irrigation pipe, and a floating plate is provided in the water storage ditch between the upper and lower inner walls of the drain pipe, and is connected to the water stop plug by a pull rope.

[0017] In a further technical solution, the drip irrigation hole is connected to an extension pipe, and the extension pipe is connected to a plurality of immersion pipes arranged in a divergent shape.

[0018] In a further technical solution, a plurality of drainage ditches are provided and arranged at intervals on the slope surface of the slope rock mass.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. The present invention significantly enhances the overall structural stability of the slope, not only reducing the direct scouring effect of rainwater on the slope, but also effectively inhibiting the occurrence of soil erosion, thereby improving the durability of the greening effect, achieving the harmonious unity of ecological restoration, environmental beautification and slope protection, effectively reducing the risk of geological disasters such as landslides or collapses, and providing safety guarantees for the safe operation of railways.

[0021] 2. When faced with the challenge of rainwater scouring, the present invention uses a drainage system composed of a gutter assembly, a drainage ditch and a drainage ditch to quickly discharge rainwater from the slope and inside the grid beam, thereby effectively preventing the accumulation of rainwater on the slope, reducing the degree of erosion of rock and soil under the accumulation of rainwater, avoiding potential safety hazards caused by excessive water accumulation, and further ensuring the safety and stability of the slope.

[0022] 3. The water storage ditch of the present invention can not only cut off the top and slope surface, greatly reducing the amount of rainwater flowing from the top to the slope surface, thereby effectively reducing the degree of scouring of the slope surface by rainwater, but also has the function of collecting and storing rainwater. In clear weather, the water storage ditch uses the water stored in rainy days through drip irrigation pipes and drip irrigation holes to provide water supply for the green plants on the slope, effectively improving the moisture content of the soil, creating more favorable conditions for the growth and development of plants, and significantly improving the survival rate of green plants. As the roots of green plants take root deeply in the rock and soil, the stability of the slope is further enhanced, which not only reduces the direct scouring effect of rainwater on the slope surface, but also effectively inhibits the occurrence of soil erosion, thereby improving the durability of the greening effect.

[0023] 4. The present invention fully considers the impact of different slopes on the growth and development of vegetation. By planting climbing vegetation and / or hanging vegetation and mixed vegetation of trees, shrubs and grasses on gentle slopes, and using vegetation bag technology instead of traditional planting methods on steep slopes, the slope surface can be quickly covered to form a greening effect. It also significantly improves the survival rate of vegetation, significantly enhances the stability and erosion resistance of the slope, and lays a solid foundation for the ecological restoration of the slope area.

[0024] 5. The present invention effectively solves the risk of overflow caused by excessive water accumulation in the water storage ditch in the case of heavy or continuous rainfall through the design of the drainage pipe. The cooperation of the floating plate, the pull rope and the water stop plug effectively controls the amount of water supplied to the green plants by the drip irrigation pipe, which can ensure the growth and development of green plants and prevent the stability of the rock and soil structure caused by excessive soil moisture content, providing a solid guarantee for the safety, stability and ecological restoration of the slope.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See Figures 1-6 The present invention provides a railway civil engineering greening protection device, comprising a slope rock mass 1, a water storage ditch 2 arranged at the top of the slope rock mass 1, and a retaining wall 3 and a drainage ditch 4 arranged at the foot of the slope rock mass 1. Anchor rods 5 are provided in the slope rock mass 1, and a grid beam and a drainage facility are provided on the slope surface of the slope rock mass 1. Green plants are planted in the grid beam. The drainage facility comprises a drainage ditch 6 and a drainage trough assembly. The drainage ditch 6 is arranged along the slope surface of the slope rock mass 1, and the tail end of the drainage ditch 6 can guide water to the drainage ditch 4. The drainage trough assembly is arranged on the grid beam and can guide the water in the grid beam to the drainage ditch 6. A plurality of drip irrigation pipes 7 are connected below the water storage ditch 2. The drip irrigation pipes 7 are buried in the slope rock mass 1 and are located below the green plants. A plurality of drip irrigation holes are opened below the drip irrigation pipe 7.

[0035] This greening protection device is designed to protect the stability of the slope and promote the growth of vegetation, thereby achieving harmonious coexistence of the ecological environment along the railway. Through the combined design of anchor rods 5, grid beams and retaining walls 3, the overall structural stability of the slope is significantly enhanced, reducing the risk of geological disasters such as landslides or collapses. When faced with the challenge of rainwater erosion, this greening protection device uses a drainage system composed of a drainage trough assembly set on the grid beam, a drainage ditch 6 on the slope surface of the slope rock mass 1, and a drainage ditch 4 at the foot of the slope rock mass 1. Its operation effectively reduces the erosion of water on the slope, further ensuring the safety and stability of the slope. Specifically, the drainage trough assembly set on the grid beam can quickly and effectively guide rainwater accumulated on the slope surface and inside the grid beam to the drainage ditch 6, avoiding potential safety hazards caused by excessive water accumulation. The drainage ditch 6 is used to collect rainwater on the slope and smoothly guide this water to the drainage ditch 4 at the foot of the slope rock mass 1, ensuring that the accumulated water can be quickly and thoroughly discharged from the slope area, thereby effectively preventing the accumulation of rainwater on the slope and reducing the degree of erosion of rock and soil under the accumulation of rainwater. In addition, the greening protection device also sets a water storage ditch 2 at the top of the slope rock mass 1. This design not only can cut off the top and the slope, but also greatly reduces the amount of rainwater flowing from the top to the slope compared to traditional slope structures, thereby effectively reducing the degree of rainwater erosion on the slope. In addition, the water storage ditch 2 also has the function of collecting and storing rainwater. In clear weather, the water storage ditch 2 uses the water stored during rainy days through the drip irrigation pipe 7 and drip irrigation holes to provide water supply for the green plants on the slope, effectively improving the moisture content of the soil, creating more favorable conditions for the growth and development of plants, and significantly improving the survival rate of green plants. As the roots of the greening plants take root deeply in the rock and soil, the stability of the slope is further enhanced. This not only reduces the direct scouring effect of rainwater on the slope, but also effectively inhibits soil erosion, thereby improving the durability of the greening effect. At the same time, the growth and flourishing of greening plants further beautify the environmental landscape of the slope, achieving a harmonious unity of ecological restoration, environmental beautification, and slope protection. This effectively reduces the risk of geological disasters such as landslides and collapses, and provides security for the safe operation of the railway.

[0036] In a specific embodiment, see Figure 1 and Figure 4 The slope rock mass 1 is formed by a high steep slope section 8 and a gentle slope section 9 which are arranged continuously at intervals. The high steep slope section 8 and the gentle slope section 9 are both provided with grid beams. Climbing vegetation and / or hanging vegetation as well as mixed vegetation of trees, shrubs and grasses are planted in the grid beams of the gentle slope section 9.

[0037] The design of the high-steep slope section 8 and the gentle slope section 9 fully considers the impact of different slopes on the growth and development of vegetation. Specifically, the high-steep slope section 8 has a steep slope, poor soil and poor water retention capacity, which makes the vegetation growth environment relatively harsh. In contrast, the gentle slope section 9 provides more favorable conditions for the growth of vegetation because of its gentle slope, fertile soil and easy water retention. By planting climbing vegetation and / or hanging vegetation in the grid beams of the gentle slope section 9, these vegetation can climb or hang quickly, and can quickly cover and beautify the high-steep slope section 8, forming a vertical greening effect. At the same time, in the gentle slope section 9, in addition to planting climbing and / or hanging vegetation, mixed vegetation of trees, shrubs and grasses is also rationally arranged to construct a multi-level ecosystem, which can not only protect the seedlings of climbing and / or hanging vegetation, increase the survival rate of climbing vegetation and hanging vegetation, but also further enhance the overall greening effect of vegetation. Furthermore, by rapidly covering the steep slope section 8 with vegetation from the gentle slope section 9, the steep slope section 8 provides necessary shade and protection for the seedlings there. This helps reduce the damage these seedlings suffer from direct exposure to strong sunlight and adverse weather conditions, significantly increasing their survival rate. This design not only enhances the slope's protective capabilities but also significantly improves the overall greening effect, laying a solid foundation for ecological restoration in the slope area.

[0038] In a specific embodiment, see Figure 2 The grid beam of the steep slope section 8 is equipped with a slope protection component and a vegetation bag. The slope protection component includes a metal mesh and a flexible protective net 10. The metal mesh and the flexible protective net 10 are sequentially covered on the slope surface of the steep slope section 8. The vegetation bag is tied to the metal mesh, and the flexible protective net 10 covers the outside of the vegetation bag.

[0039] Since the vegetation growth environment in the steep slope section 8 is relatively harsh, traditional planting methods are difficult to ensure the effective survival and growth of vegetation. Therefore, this greening protection device uses vegetation bag technology to replace traditional planting methods, which not only improves the survival rate of vegetation, but also effectively reduces long-term maintenance costs. Specifically, the vegetation bag is filled with a mixture of soil and seeds suitable for local climate and soil conditions. The seeds used are all plant species with well-developed root systems, strong adaptability, and rapid growth, such as vine plants. These plants can not only quickly climb and cover the slope surface, but also effectively fix the soil through their strong root systems. During the use of the vegetation bag, by tying the vegetation bag to the metal mesh and then covering the outside with a flexible protective net 10, the vegetation bag can be effectively prevented from being displaced or damaged by wind or rain erosion, providing additional protection for the seeds and seedlings in the vegetation bag, while ensuring the smooth penetration and absorption of water and nutrients. As the seeds germinate and the vegetation grows, its roots gradually penetrate into the rock and soil, forming a strong soil-fixing network, which significantly enhances the stability and erosion resistance of the steep slope section 8 and effectively prevents soil and water loss. At the same time, the vegetation cover also reduces the direct impact of rainwater on the slope surface of the steep slope section 8, ensuring the integrity and safety of the slope surface.

[0040] In a specific embodiment, see Figure 3 The grid beam includes multiple longitudinal characteristic beams 11 and multiple transverse characteristic beams 12. The longitudinal characteristic beams 11 and the transverse characteristic beams 12 are vertically connected. The longitudinal characteristic beams 11 of the upper and lower adjacent layers of the grid beam of the steep slope section 8 are staggered to form a mesh structure.

[0041] The perpendicular intersection of longitudinal characteristic beams 11 and transverse characteristic beams 12 not only enhances the overall stability and load-bearing capacity of the grid beams, but also provides a solid support framework for vegetation growth. In the steep slope section 8, the staggered arrangement of longitudinal characteristic beams 11 in the upper and lower layers of the grid beams creates a mesh structure. This not only optimizes the force distribution within the grid beams, but also enables each beam to more effectively share and resist external loads, thereby improving the stability and safety of the entire slope structure.

[0042] In a specific embodiment, see Figure 1 and Figure 2The drain trough assembly includes a longitudinal drain trough 13, a first transverse inclined drain trough 14, a second transverse inclined drain trough 15 and a total drain trough 16. The longitudinal drain trough 13 is vertically arranged on the longitudinal characteristic beam 11. The first transverse inclined drain trough 14 and the second transverse inclined drain trough 15 are both vertically arranged on the transverse characteristic beam 12 and are respectively located on both sides of the longitudinal drain trough 13. The water left by the upper longitudinal drain trough 13 can be guided to the longitudinal drain trough 13 below. The total drain trough 16 is installed in the gentle slope section 9 and is located below the water outlet of the corresponding longitudinal drain trough 13. It is used to receive the water left by the longitudinal drain trough 13 and guide the water into the drainage ditch 6.

[0043] A drainage network consisting of longitudinal troughs 13, first transverse inclined troughs 14, second transverse inclined troughs 15, and a main trough 16 efficiently collects and directs water from the slope or vegetation through step-by-step guidance and dispersion. This prevents water accumulation on the slope, effectively reduces soil erosion caused by prolonged water accumulation, and significantly reduces the risk of slope instability due to water saturation. Within this drainage network, the main trough 16 collects collected rainwater and directs it into the drainage ditch 6, ensuring an efficient and orderly drainage process and providing a solid guarantee for the stability and safety of the slope.

[0044] In a specific embodiment, the first transverse inclined drain trough 14 and the second transverse inclined drain trough 15 are both L-shaped and inclined toward one side of the lower longitudinal drain trough 13 .

[0045] Both the first transverse inclined drain trough 14 and the second transverse inclined drain trough 15 are L-shaped, with their outer edges acting as baffles to prevent water from splashing during flow and further eroding the slope rock and soil, reducing the risk of soil erosion. The first and second transverse inclined drain troughs 14, 15 are tilted toward one side of the longitudinal drain trough 13 below, ensuring that water flows smoothly and efficiently along a predetermined path into the longitudinal drain trough 13, providing strong support for efficient drainage.

[0046] In a specific embodiment, see Figure 1 and Figure 4 A drainage pipe 17 is connected to the upper side wall of the water storage ditch 2, and the drainage pipe 17 extends through the slope rock mass 1 and is connected to the drainage ditch 6.

[0047] The design of the drain pipe 17 effectively eliminates the risk of overflow caused by excessive water accumulation in the water storage ditch 2. In the event of heavy or sustained rainfall, the water level in the water storage ditch 2 will continue to rise. Once the water level in the water storage ditch 2 reaches the height of the drain pipe 17, the excess rainwater will quickly flow through the drain pipe 17 into the drainage ditch 6 and be efficiently discharged along the path of the drainage ditch 6 to the drainage ditch 4. This reduces the impact of heavy or sustained rainfall on the greening protection device and provides a solid guarantee for the safety, stability and ecological restoration of the slope.

[0048] In a specific embodiment, see Figure 4 and Figure 5 A water supply pipe 18 is provided at the bottom of the water storage ditch 2. The diameter of the water supply pipe 18 is smaller than that of the drip irrigation pipe 7, and the water supply pipe 18 is connected to the drip irrigation pipe 7. A water stopper 19 with a diameter larger than that of the water supply pipe 18 is provided in the drip irrigation pipe 7. A floating plate 20 is provided in the water storage ditch 2 between the upper and lower inner walls of the drain pipe 17, and is connected to the water stopper 19 through a pull rope 21.

[0049] Through the coordinated operation of the float plate 20, the pull rope 21, and the water stopper 19, when the water level in the water storage ditch 2 reaches a preset height, the float plate 20 rises with the rising water level. Leveraging the traction of the pull rope 21, the water stopper 19 is pulled tightly against the water supply pipe 18, thereby triggering the water stopper 19's sealing mechanism. During rainfall, the amount of water supplied to the green plants by the drip irrigation pipe 7 is significantly reduced, thereby preventing geotechnical structural stability issues that may arise from excessive soil moisture. As the rainfall subsides, the water level in the water storage ditch 2 gradually drops due to the effective drainage of the drain pipe 17. At this point, the float plate 20 descends with the lowering water level, disengaging the water stopper 19 from the water supply pipe 18 and ensuring that the water supply pipe 18 is unobstructed. This allows the drip irrigation pipe 7 to once again provide the appropriate amount of water to the green plants, ensuring the appropriate moisture conditions for their growth and development, thereby effectively supporting the implementation of slope greening projects, ecosystem restoration, and long-term maintenance and management.

[0050] In a specific embodiment, see Figure 6 The drip irrigation hole is connected to an extension pipe 22, and the extension pipe 22 is connected to a plurality of immersion pipes 23 arranged in a divergent shape.

[0051] The extension pipe 22 and the immersion pipe 23 arranged divergently on the extension pipe 22 ensure that the irrigation water can be evenly and deeply distributed in the soil, effectively avoiding the uneven plant growth caused by excessive concentration or severe shortage of local water, effectively improving the soil moisture condition, and providing more favorable environmental conditions for plant growth.

[0052] In a specific embodiment, a plurality of drainage ditches 6 are provided and arranged at intervals on the slope surface of the slope rock mass 1 .

[0053] Through the joint action of multiple drainage ditches 6, the overall drainage efficiency of the greening protection device is effectively improved, the accumulation of rainwater on the slope is prevented, and the degree of erosion of rock and soil under the accumulation of rainwater is greatly reduced, providing a strong guarantee for the stability of the slope and ecological restoration.
