Description

Technical Field

[0001] This invention belongs to the field of arid steep slope restoration technology, specifically relating to a steep slope structure and irrigation device in arid regions. Background Technology

[0002] Arid regions experience low rainfall, intense evaporation, and scarce water resources. Rainfall is often concentrated in short-duration downpours and is unevenly distributed in time and space. On steep slopes, due to the steep gradient and rapid runoff, rainfall is difficult to infiltrate and store locally. Most rainwater quickly forms surface runoff and is lost along the slope, resulting in low soil moisture content, severe soil erosion, and difficulties in vegetation restoration and crop growth.

[0003] Existing steep slope structures do not adequately consider rainwater collection, storage, and sustainable utilization, resulting in problems such as small water storage capacity, poor seepage prevention, and easy evaporation and infiltration. Furthermore, the water stored after rainfall is difficult to retain for long periods, drying out quickly during the dry season, and ditches are prone to siltation and blockage, making maintenance difficult. Overall, the water storage effect is poor, failing to meet the water conservation, water storage, and drought resistance needs of steep slopes in arid regions. In addition, existing irrigation methods mostly rely on manual water transport, which is labor-intensive, inefficient, and provides unsustainable water supply, making it difficult to achieve on-demand, water-saving, and stable irrigation, and thus requires improvement. Summary of the Invention

[0004] In order to solve all or some of the above problems, the present invention aims to provide a steep slope structure and irrigation device for arid areas, which can improve the problems of difficulty in fully utilizing rainwater on steep slopes in arid areas, discontinuous watering of slope vegetation, and high labor intensity of manual irrigation.

[0005] In a first aspect, the present invention provides a steep slope structure in arid regions, comprising a steep slope body, characterized in that a drainage ditch is provided at the middle position of the slope surface of the steep slope body, so that the slope surface of the steep slope body forms two symmetrically arranged planting areas, each of the planting areas comprising a plurality of alternately arranged planting slopes and planting paths, and each of the planting slopes and planting paths is planted with drought-resistant vegetation. Each of the planting trails is equipped with a water interception ditch, and each of the planting slopes is equipped with a communicating vessel assembly for collecting and storing rainwater. The communicating vessel assembly is connected to the roots of the drought-resistant vegetation through several water-conducting capillaries.

[0006] Optionally, the communicating vessel assembly includes a main communicating pipe and multiple branch communicating pipes. The main communicating pipe is buried in the planting slope. The bottoms of the multiple branch communicating pipes are respectively connected to the main communicating pipe, and the tops are respectively exposed above the planting slope. The water-conducting capillary extends from the corresponding branch communicating pipe into the main communicating pipe.

[0007] Optionally, the main connecting pipe and the branch connecting pipe are respectively arranged in a spiral shape.

[0008] Optionally, the planting path is 0.5-1.5m wide, the drainage ditch is inverted trapezoidal, and the drainage ditch has an upper bottom width of 20-35cm, a lower bottom width of 15-25cm, and a depth of 25-35cm.

[0009] Optionally, the drainage ditch is provided with walking steps. The drainage ditch is 60-80cm wide, the walking steps are 25-35cm high and 45-55cm wide, and there is a gap of not less than 10cm between the two sides of the walking steps and the inner wall of the drainage ditch.

[0010] Optionally, each of the planting walkways is inclined at 5-10° toward the drainage ditch.

[0011] Secondly, the present invention provides an irrigation device for steep slope structures in arid regions, comprising: Irrigation tracks are installed at the top of the steep slope. An irrigation cart for sliding along the irrigation track; An irrigation water tank is installed on the irrigation vehicle; An irrigation pipe assembly is installed on the irrigation tank and is used to spray water or pesticides onto the drought-resistant vegetation on the planting path and the planting slope.

[0012] Optionally, the irrigation pipe assembly includes: The irrigation main pipe is connected to the irrigation water tank; Multiple irrigation branch pipes are vertically connected to the main irrigation pipe, and the multiple irrigation branch pipes are correspondingly arranged with the planting walkway and the planting slope. Each irrigation branch pipe is connected to a large irrigation nozzle, a medium irrigation nozzle, and a pesticide nozzle at its bottom. The large irrigation nozzle is used to spray water on the canopy of drought-resistant vegetation, the medium irrigation nozzle is used to spray water on the roots of drought-resistant vegetation, and the pesticide nozzle is used to spray pesticides on drought-resistant vegetation.

[0013] Optionally, the irrigation track includes a plurality of parallel guide rails, each guide rail including a first telescopic rail and a second telescopic rail hinged together, and a jacking mechanism is provided below each of the first telescopic rails and the second telescopic rail, and the telescopic end of the jacking mechanism is hinged to the corresponding first telescopic rail or the second telescopic rail.

[0014] Optionally, each of the first telescopic track and the corresponding second telescopic track is provided with a first magnet at one end that is far apart from each other, and the irrigation vehicle is provided with a second magnet at the front and rear sides, and the magnetic poles of the second magnets repel the corresponding first magnets.

[0015] As can be seen from the above technical solution, the steep slope structure and irrigation device for arid areas provided by the present invention have the following advantages: 1. The slope uses a combination of graded planting walkways, intercepting ditches and communicating vessel components to retain a portion of the water from short-term rainfall near the plant root zone and continue to be used as the soil gradually dries. 2. The drainage ditch in the middle of the slope can receive excess water from each layer in a timely manner, so that the slope water storage and slope drainage are divided into functions. 3. The drainage ditch also serves as a walking passage, which is beneficial for later water replenishment, chemical addition, and maintenance; 4. The mobile irrigation device on the slope top can provide targeted supplementary irrigation for the tree canopy, roots and slope vegetation, reducing the need for workers to directly enter steep slopes for work. 5. The irrigation vehicle's direction of movement can be changed by using liftable and extendable tracks, which reduces reliance on complex traction structures to complete reciprocating irrigation.

[0016] Other features and advantages of the present invention will be set forth in the following description. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be arbitrarily combined with each other.

[0021] Example 1 like Figure 1 The illustration shows Embodiment 1 of the present invention, which discloses a steep slope structure in arid regions, including a steep slope body 1. The steep slope body 1 can be a natural slope, an artificial slope, or a similar slope body after hazard mitigation, slope shaping, and foundation drainage treatment. For ease of explanation, in this embodiment, the direction from the top of the slope to the bottom of the slope is understood as the slope direction, and the direction that traverses the slope surface laterally at the same height is understood as the lateral direction.

[0022] like Figure 1 As shown, a drainage ditch 2 is set along the slope direction in the middle of the slope, and the drainage ditch 2 extends from the top of the slope to the bottom of the slope, so that the drainage ditch 2 divides the slope into two planting areas 3 on the left and right. The two planting areas 3 can be symmetrical, or they can be locally adjusted according to the site boundary.

[0023] like Figure 1 As shown, within each planting area 3, multiple planting slopes 32 and planting paths 31 are sequentially set along the slope direction. The planting path 31 can be understood as a relatively gentle platform-like area formed on the original steep slope, providing planting and maintenance space for drought-resistant vegetation and dividing a long, continuous slope into several shorter segments. The planting slope 32 is a sloping area that maintains the slope between adjacent planting paths 31. By alternating between planting slopes 32 and planting paths 31, the runoff that originally flowed rapidly down the entire steep slope can be divided into multiple segments for treatment.

[0024] In this embodiment, drought-resistant vegetation can be selected based on local climate, soil quality, and restoration goals. For example, drought-resistant shrubs or dwarf trees can be planted on the planting path 31, while drought-resistant herbs, ground cover plants, or slope protection plants with well-developed root systems can be planted on the planting slope 32. It is not required that only one type of plant be planted in different areas; in actual construction, combinations of trees, shrubs, and grasses, shrubs and grasses, or other plant combinations suitable for the local habitat can be used.

[0025] like Figure 1 As shown, each planting walkway 31 is equipped with a water interception ditch 4 to receive rainwater or irrigation wastewater flowing down from the planting slope 32 above, and to allow the water to stay in this layer first, rather than continuing to directly wash the next level of slope.

[0026] In this embodiment, the intercepting ditch 4 can be set near the boundary area between the planting path 31 and the upper planting slope 32, and extend along the path. At the same time, when the intercepting ditch 4 adopts an inverted trapezoidal cross section, the upper opening is relatively wide, which facilitates the reception of water from the slope and also facilitates the later manual removal of small amounts of soil, fallen leaves and gravel that have entered the ditch.

[0027] like Figure 1As shown, the width of the planting walkway 31 can be selected within the range of 0.5-1.5m. For example, for slope sections where dwarf trees need to be planted and a certain maintenance space is required, a planting walkway 31 approximately 1m wide can be used. The top width of the intercepting ditch 4 can be 20-35cm, the bottom width can be 15-25cm, and the depth can be 25-35cm. For example, the top width of the intercepting ditch 4 is approximately 30cm, the bottom width is approximately 20cm, and the depth is approximately 30cm.

[0028] like Figure 1 As shown, to concentrate excess water on the same planting walkway 31 towards the middle of the slope, each planting walkway 31 can be inclined laterally at 5-10° towards the drainage ditch 2. Simply put, at the same height, the position near the outer edge of the steep slope can be slightly higher, and the position near the middle drainage ditch 2 can be slightly lower. When rainfall is heavy or irrigation exceeds the amount of water available to the plants in this layer for a short period, water will gradually move along the walkway and intercepting ditch 4 towards the lower middle part, eventually entering the drainage ditch 2, thus preventing rainwater from stagnating locally on the planting walkway 31 for extended periods.

[0029] like Figure 1 As shown, walking steps 7 are installed in the drainage ditch 2, and the walking steps 7 are set up step by step along the slope. Workers can step on the steps to reach the top of the slope or the planting walkway 31 at different heights. In this way, the drainage ditch 2 not only serves the function of drainage, but also takes into account the function of maintaining passage, so there is no need to set up a continuous pedestrian walkway in the planting area 3, thereby reducing the occupation of the vegetation area.

[0030] In this embodiment, the width of the drainage ditch 2 can be 60-80cm, preferably 70cm. The height of the walking steps 7 can be 25-35cm, preferably 30cm. The width of the steps can be 45-55cm, preferably 50cm. A gap of not less than 10cm, preferably 15cm, is maintained between each side of the walking steps 7 and the inner wall of the drainage ditch 2. This gap provides a continuous channel for water flow and small amounts of mud, sand, and gravel carried in by the water, so that even if the steps occupy part of the cross-section of the middle of the drainage ditch 2, water can still flow downward from both sides of the steps.

[0031] like Figure 1 As shown, each planting slope 32 is equipped with a communicating vessel assembly 5 for collecting and storing rainwater, and the communicating vessel assembly 5 is connected to the roots of drought-resistant vegetation through several water-conducting capillary lines 6. The communicating vessel assembly 5 is used to store a portion of short-term rainwater or irrigation water near the root zone. Compared with setting up a large-scale water storage layer throughout the slope, this local water storage method makes it easier to control the scope of water action, so that the water mainly serves the nearby vegetation, rather than soaking the entire slope for a long time.

[0032] like Figure 1As shown, the communicating vessel assembly 5 includes a main communicating pipe 51 and multiple branch communicating pipes 52. The main communicating pipe 51 is buried in the soil of the planting slope 32, serving as a relatively centralized water storage space. The multiple branch communicating pipes 52 are integrally formed and connected to the main communicating pipe 51, and the upper end of the branch communicating pipes 52 is partially exposed on the slope surface so that water can enter from the pipe opening during rainfall or artificial watering, while the rest of the pipe body remains within the soil layer.

[0033] In this embodiment, the communicating vessel assembly 5 can be made of transparent or semi-transparent material, or at least a transparent observation section can be set in a position that is easy to observe, so that maintenance personnel can observe whether there is water stored in the communicating vessel assembly or whether a lot of soil has entered through the transparent part, and can also judge the moisture status of the root zone in combination with the surrounding soil conditions.

[0034] like Figure 1 As shown, the main connecting pipe 51 and the branch connecting pipe 52 are arranged in a spiral shape. Within the limited burial range on the slope, the spiral path can increase the pipe length, thereby increasing the water capacity. At the same time, rainwater needs to travel a longer path after entering before migrating between different pipe sections, which can slow down the rapid concentration of water in a certain location.

[0035] like Figure 1 As shown, one end of the water-conducting capillary 6 can extend into the connecting main pipe 51 or contact the water storage inside the connecting main pipe 51, while the other end extends to the vicinity of the roots of the drought-resistant vegetation. "Vicinity of the roots" refers to the soil area where the plant's main root system can absorb water. It is not required that the capillary 6 directly contact the plant's root surface. When the root zone is relatively dry, the water in the connecting main pipe 51 can gradually migrate towards the root zone along the capillary 6, forming a relatively slow water replenishment.

[0036] In other embodiments, an impermeable covering layer can be provided on the outside of the non-water supply section between the water storage structure and the root zone of the water-conducting capillary 6 to reduce water loss to non-target soil layers midway and allow more water to reach the vicinity of the root zone.

[0037] During rainfall or irrigation, the soil moisture content on the slope increases, and some water flows from the exposed connecting branch pipe 52 into the connecting main pipe 51 and is temporarily stored. At the same time, the intercepting ditch 4 intercepts the water flowing along the slope. As rainfall continues, if the water storage space and soil can no longer absorb more water, the excess water will flow along the sloping planting path 31 to the drainage ditch 2, forming a pattern of first utilizing the water locally and then smoothly draining the excess rainwater.

[0038] Once the drought phase begins, there is no longer significant runoff on the slope, and some of the water previously stored in the main pipe 51 remains near the root zone. As the root zone dries out, the water-conducting capillaries 6 allow this water to gradually migrate towards the root zone, thus extending the utilization time of a single rainfall or irrigation. In practical applications, artificial watering can be focused on the exposed openings of the branch pipes 52, rather than flooding the entire slope with large volumes of water. This allows for control of the overall slope moisture content while prioritizing available water near the plant roots.

[0039] Example 2 like Figure 2 The illustration shows Embodiment 2 of the present invention, which discloses an irrigation device for a steep slope structure in arid regions. The device includes an irrigation track 8, an irrigation vehicle 9, an irrigation water tank 10, and an irrigation pipe assembly 11. The irrigation track 8 is positioned on the top of the slope. The irrigation vehicle 9 moves along the irrigation track 8 at the top of the slope. The irrigation water tank 10 is mounted on the irrigation vehicle 9, and the irrigation pipe assembly 11 is mounted on the irrigation water tank 10. Because the irrigation water tank 10 and the irrigation pipe assembly 11 can move together with the irrigation vehicle 9, workers can mainly complete water addition, chemical addition, and control at the top of the slope, without needing to carry water supply equipment into each level of the steep slope.

[0040] like Figure 2 As shown, the irrigation track 8 includes multiple parallel guide tracks 81, which together support and guide the irrigation vehicle 9. Each guide track 81 includes a first telescopic track 811 and a second telescopic track 812, and the first telescopic track 811 and the second telescopic track 812 are hinged together.

[0041] In this embodiment, the telescopic track can be understood as a track itself having a socket structure that can change the effective length. For example, hollow track segments with different cross-sectional dimensions can be interlocked, so that one segment can extend or retract relative to the other segment.

[0042] like Figure 2 As shown, a jacking mechanism 813 is respectively installed below each of the first telescopic rails 811 and the second telescopic rails 812. One end of the jacking mechanism 813 can be connected to the slope top foundation or a fixed support position, and the telescopic end is hinged to the corresponding first telescopic rail 811 or second telescopic rail 812. When the jacking mechanism 813 extends, the corresponding rail segment is raised; when the jacking mechanism 813 shortens, the corresponding rail segment descends. Because there is a hinged relationship between adjacent rail segments, the rails can form a continuous inclined trend when different positions are raised to different heights.

[0043] In this embodiment, the jacking mechanism 813 adopts a remotely controllable lifting support rod, or an electric linear lifting mechanism. Of course, in places with corresponding hydraulic conditions, a hydraulic lifting mechanism can also be used.

[0044] In this embodiment, the bottom of the irrigation vehicle 9 is equipped with multiple sets of pulleys, which cooperate with the corresponding tracks. Furthermore, the pulleys can be equipped with anti-derailment structures to ensure that the irrigation vehicle 9 remains constrained by the tracks even when there is a certain degree of inclination. The pulley structure can employ flanged rollers, rollers with locking mechanisms, or other conventional forms capable of rolling along the tracks and limiting lateral derailment.

[0045] like Figure 2 As shown, the irrigation pipe assembly 11 includes a main irrigation pipe 111 and multiple branch irrigation pipes 112. The main irrigation pipe 111 is horizontally connected to the irrigation vehicle 9, and the multiple branch irrigation pipes 112 extend vertically downward from the main irrigation pipe 111. Because there are multiple planting walkways 31 and planting slopes 32 on the slope, different branch irrigation pipes 112 can have different downward extension lengths, allowing the sprinklers to correspond to different heights of the tree canopy, root zone, or drought-resistant grass area. In other words, when the irrigation vehicle 9 moves laterally at the top of the slope, the multiple branch pipes effectively guide the sap supply from the top of the slope to the vicinity of vegetation at different heights.

[0046] like Figure 2 As shown, each irrigation branch pipe 112 is equipped with a large irrigation nozzle 113, a medium irrigation nozzle 114, and a pesticide sprayer 115 at its bottom. The large irrigation nozzle 113 is used to spray water towards the canopy area of ​​drought-resistant shrubs or dwarf trees, providing relatively large coverage. The medium irrigation nozzle 114 is used to spray water towards the soil around the tree roots, ensuring that water reaches the root zone rather than being sprayed entirely onto the branches and leaves. The pesticide sprayer 115 is used to spray appropriate pesticides when pest and disease control or maintenance is required. In actual use, one or more nozzles can be selected to operate according to the specific operational objectives; it is not required that all nozzles be on simultaneously.

[0047] In some embodiments, dust blowing nozzles may be added to the irrigation branch pipe 112, and a blower mechanism may be installed on the irrigation vehicle 9. The dust blowing nozzles can blow air toward the intercepting ditch 4 or the surface of the walkway to push lighter dust, fallen leaves or small particles of debris toward the central drainage ditch 2, helping to keep the drainage paths of the intercepting ditch 4 and the walkway unobstructed.

[0048] In this embodiment, the irrigation main pipe 111 and the irrigation water tank 10 are kept in fluid communication, and the specific liquid supply method can be determined according to the conditions of the equipment at the top of the slope. For example, when the water tank has a sufficient liquid level, water can be supplied using the liquid level pressure difference. When a more stable spraying pressure is required, a conventional liquid supply mechanism can also be configured to deliver water or chemical solution into the irrigation main pipe 111.

[0049] To enable the irrigation vehicle 9 to move along the track without relying on a continuous traction device, this embodiment utilizes a jacking mechanism 813 to change the height of different positions on the track. For example, when the irrigation vehicle 9 moves from the first end to the second end, several sections of the track near the first end can be raised sequentially, with the higher the section closer to the first end, the greater the elevation. In this way, the track forms a downward trend from the first end to the middle, allowing the irrigation vehicle 9 to slide along the track at a lower elevation under its own weight.

[0050] Specifically, as the irrigation truck 9 moves to the right, the leftmost track is raised by 60cm, the adjacent track by 40cm, and the next track by 20cm, while the remaining tracks remain lower, creating a gradually descending track. The 60cm, 40cm, and 20cm heights mentioned above are just examples illustrating the working method; the actual raising height should be determined based on the track length, the weight of the irrigation truck 9, rolling resistance, and the permissible speed on site. When the irrigation truck 9 needs to move in the opposite direction, the previously raised side can be lowered, and the other side raised using the same method, reversing the direction of descent. In this way, the irrigation truck 9 can move back and forth by varying the track height. Since the raising and lowering mainly occur at the top of the slope, workers do not need to pull the irrigation truck 9 along the steep slope, reducing the need for strenuous operations on the slope.

[0051] like Figure 2 As shown, each of the first telescopic rails 811 and the corresponding second telescopic rails 812 has a first magnet 12 at its far ends, and a second magnet 13 is provided on the front and rear sides of the irrigation vehicle 9, with adjacent first magnets 12 and second magnets 13 having the same magnetic poles facing each other. When the irrigation vehicle 9 approaches the end of the rail, the repulsive magnetic force gradually increases, which can form a non-contact buffer for the irrigation vehicle 9, reducing the possibility of the vehicle body directly impacting the end of the rail. When the end is lifted by the pushing mechanism 813 and the rail begins to descend in the opposite direction, the repulsive magnetic force can assist the irrigation vehicle 9 in quickly leaving the end, reducing the external force required to overcome static resistance when starting.

[0052] The following describes the operation process of this embodiment using a complete irrigation process as an example: Before the operation, the staff checked the drainage ditch 2, intercepting ditch 4, and communicating vessel assembly 5 at the top of the slope for any obvious blockages. They also determined whether additional water was needed based on recent rainfall, plant condition, and the water storage in the communicating vessel assembly 5. If there had been sufficient rainfall recently and the communicating vessel assembly 5 still had usable stored water, the number of irrigations could be reduced or the spraying time shortened. If the drought continued, the amount of water to be added could be increased.

[0053] When irrigation is needed, irrigation water or chemicals are first added to the irrigation tank 10. Then, according to the planned direction of movement, the pushing mechanism 813 on one side is raised step by step, so that the track is in a state of descending to the other side. The irrigation vehicle 9 begins to move along the track under the action of gravity, and the irrigation main pipe 111 and each irrigation branch pipe 112 move synchronously with the vehicle.

[0054] When the irrigation truck 9 passes through an area planted with dwarf trees or shrubs, the large irrigation nozzles 113 can be turned on to spray water onto the tree canopy. When it is necessary to replenish the root zone with water, the canopy spray can be turned off or reduced, and the medium-sized irrigation nozzles 114 can be turned on to allow water to fall directly around the tree roots. If the drought-resistant grasses on the planted slope 32 need watering, the position of the branch pipes or nozzles corresponding to that slope can be adjusted to cover the area where the herbaceous plants are located. Since different branch pipes correspond to different heights, the irrigation truck 9 can cover multiple layers of the slope in one lateral movement.

[0055] If pest and disease control is required, the pesticide sprayer 115 can be used during the same movement. To avoid mixing the pesticide solution with ordinary irrigation water, an independent storage space and corresponding liquid path can be used. If the device is also equipped with a dust blowing function, the blower mechanism can be activated when the irrigation truck 9 passes over the intercepting ditch 4, and the dust blowing nozzles can push loose dust and small particles of debris along the ditch towards the central drainage ditch 2, making it easier for subsequent rainfall or irrigation wastewater to flow along the ditch.

[0056] When the irrigation vehicle 9 reaches the other end of the track, it first stops spraying and then adjusts the jacking mechanism 813 to gradually raise the track at that end and lower the original high end, thus creating a reverse track slope. The irrigation vehicle 9 then returns in the opposite direction. During the return process, the large irrigation nozzle 113, medium irrigation nozzle 114, or pesticide nozzle 115 can be re-selected based on the position of the plants in the planting area 3 on the other side. In this way, a single round trip can complete the watering or maintenance of multiple planting layers on both sides of the slope.

[0057] The steep slope structure and irrigation system are used as a coordinated system. During rainfall, natural water is mainly retained and utilized through walkways, intercepting ditches 4, and communicating vessel components 5. Excess water is promptly drained through the central drainage ditch 2. During periods of sustained drought, water is replenished by irrigation trucks 9 at the top of the slope. This approach makes slope water management more on-demand. For slope restoration in arid regions, this method considers both continuous water supply to the root zone and provides a clear path for overall slope drainage and maintenance.
