Description

Technical Field

[0001] The invention relates to the technical field of land improvement, in particular to a slope soil and water conservation, filtering, drainage and slope consolidation device. Background Art

[0002] Drainage and slope consolidation is achieved by setting up slope drainage ditches, intercepting ditches, underground drainage facilities, etc., to drain water from the surface and inside of the slope in a timely manner, lower the groundwater level, and reduce water infiltration, softening, and hydrostatic pressure on the slope. At the same time, engineering measures such as retaining walls, anti-slip piles, anchor rods, anchor cables, as well as biological measures such as planting trees and grass, are used to enhance the slope's anti-slip force and stability.

[0003] If natural rainfall or irrigation water cannot be properly channeled, it will easily accumulate on the land, causing the soil to be too wet, affecting the respiration of crop roots and hindering their growth. On the other hand, the indiscriminate flow of water will wash away the soil, taking away a large amount of surface soil, causing soil erosion, destroying soil fertility and structure, and reducing land productivity. Therefore, a slope soil and water conservation, filtration, drainage and slope consolidation device is needed.

[0004] However, the existing slope soil and water conservation filtration drainage slope consolidation device has the following shortcomings:

[0005] 1) Currently, the slope soil and water conservation, filtration, drainage and slope consolidation devices on the market all divert natural rainfall water through ditches and pipes to other places to prevent the land from being soaked and causing the soil to become sparse, loose and slippery. However, when the soil is not in contact with water for a long time, it is easy to cause the soil to dry out, affecting plant growth. If the soil surface is exposed to the outside for a long time, it will still cause soil erosion and landslide problems.

[0006] 2) If the excess rainwater is simply diverted to other places, it can only play a surface control role and cannot solve the fundamental problem. When the drainage channel is blocked by debris such as branches and leaves, soil erosion will still occur.

[0007] 3) When filtering a large amount of flowing water, some fine sand will still be lost with the water flow, making the soil and water conservation and slope consolidation work incomplete.

[0008] Therefore, we proposed a slope soil and water conservation, filtration, drainage and slope consolidation device to solve the above problems. Summary of the invention

[0009] The object of the present invention is to provide a slope soil and water conservation filtering, draining and slope stabilizing device. First, this device is buried under the land area to be protected. When natural rainfall occurs, the sod planted in the vegetation trough can prevent the rainwater from directly impacting and contacting the soil surface, reducing the possibility of the soil being washed away by the rainwater. When a large amount of rainwater falls on the ground, if the deep soil is saturated with moisture and no longer absorbs water, and if the surface water is also saturated, the excess rainwater will accumulate on the soil surface, soaking and softening the surface soil, making the soil easily carried away by the water flow. At this time, the vegetation trough separates the surface soil from the deep soil. When the surface soil is saturated with absorption, the rainwater can penetrate through the surface soil in the vegetation trough and leak into the diversion pipe through the filter holes on the filter trough and the diversion pipe. At this time, the filtered rainwater falls from the top of the diversion pipe onto the filter plate. At this time, the rainwater with soil is filtered again. At this time, the flowing liquid directly falls to the bottom of the diversion pipe and flows into the water pipe. At the same time, the filtered soil remains on the filter plate. In order to prevent the just-filtered soil from sliding when it still contains a large amount of moisture, it is blocked by multiple slag retaining plates to prevent it from sliding, so as to extend its time on the filter plate, so that the filtered soil can be thoroughly drained of moisture. Finally, by starting the electric telescopic rod, the slag retaining plate is driven to slide downward, and then the first motor is started to drive the scraper to slide on the filter plate, so that the dry soil is pushed by the scraper and scraped into the slag conveying pipe to solve the above problems.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The device of the present invention is buried in advance under the area of the soil to be protected. When it rains naturally, the turf in the vegetation groove avoids the direct impact of rainwater on the soil, reducing the risk of the soil being washed away. When a large amount of rain falls and the humidity of both the deep soil and the surface soil is saturated, the excess rainwater accumulates on the surface of the soil to form ponding. The soaked soil is prone to softening and loss. At this time, the vegetation groove separates the surface soil from the deep soil. After the surface soil absorbs enough water, the rainwater penetrates through the surface soil in the vegetation groove, flows into the shunt pipe through the filter holes of the filter tank and the shunt pipe, initially filtering out some of the soil carried in the rainwater. Then, the rainwater falls from the top of the shunt pipe to the filter plate, and secondary filtration occurs. The flowable liquid directly falls to the bottom of the shunt pipe and flows into the water pipe, while the soil remains on the filter plate. Considering that the just-filtered soil contains a large amount of water and is prone to sliding, a plurality of slag retaining plates on the filter plate are used to limit and block it, extending its residence time on the filter plate to ensure that the soil is completely drained of water. Finally, the electric telescopic rod drives the slag retaining plate to slide down, and at the same time, the first motor is started to drive the scraper to slide along the filter plate, pushing the dry soil into the muck conveying pipe through the scraper. The spring telescopic rod on the scraper can adaptively expand and contract to ensure that the scraper always adheres to the top of the filter plate, thereby avoiding the problem of excessive water shortage of the soil caused by using traditional ditches to divert water, which makes the soil dry for a long time and affects plant growth, and thus avoiding the problem of soil erosion caused by the long-term exposure of the soil surface due to the lack of good vegetation on the soil surface, increasing the overall stability of the slope protection.

[0025] 2. To maximize the benefit of preventing soil and water loss, while the sod protects the soil surface from being impacted by rainwater, plants with well-developed root systems are selected in the humus soil trough to reinforce the deep soil. Natural materials such as plant branches and leaves are added to the bottom of the isolation board to improve the soil air permeability and the rainwater infiltration efficiency. After its humification, it can promote the formation of soil aggregate structure, improve the ventilation and water permeability, help the growth of the roots of the green plants, retain water and fertilizer while preventing waterlogging. On the other hand, the excess rainwater seeps through the holes in the isolation board and the humus soil trough into the water diversion trough and is discharged through the water pipe. The rainwater flows into the fertilization pipe through the funnel, is blocked by the water collection trough and then led to the slow-release fertilizer box by the pipe on it. In this way, the solid fertilizer inside the slow-release fertilizer box is washed to form fertilizer water. When there is too much fertilizer water, it is diverted by the multi-layer distribution pipe to different soil layers to achieve uniform fertilization, improve the fertility of the soil in the humus soil trough, enable the green plants planted therein to grow better, realize the protection of the deep soil layer, further increase the effect of the device in preventing soil and water loss, and solve the fundamental problem of easy soil loss and landslide.

[0026] 3. When there is too much soil accumulated in the muck conveying pipe, to realize the secondary utilization of this soil, the second motor is started. The second motor drives the spiral conveyor to rotate. During the rotation of the spiral conveyor, the soil accumulated in the muck conveying pipe will be pushed out. The pushed-out soil falls on the conveyor belt. At the same time, due to the rotation of the second motor, with the cooperation of the transmission belt, the upper transmission groove and the lower transmission groove for transmission, the fixed lower transmission wheel rotates accordingly, and then drives the conveyor belt to run synchronously, transporting the soil on the conveyor belt to the ground. The soil collected before has been infiltrated and washed by water, and its fertility has been depleted. Therefore, after it is piled up on the ground, an appropriate amount of fertilizer is added for composting treatment to make the soil regain its fertility for subsequent use, further realizing the ability of the device to prevent soil and water loss, and further increasing the benefit effect of slope soil and water conservation and slope stabilization work.

[0038] The effects achieved by the entire Embodiment 1 are as follows: Rainwater penetrates through the topsoil in the vegetation trough 204, flows into the diversion pipe 202 through the filter holes on the filter trough 203 and the diversion pipe 202, completing the primary filtration and filtering out some soil. The rainwater after the primary filtration falls from the top of the diversion pipe 202 onto the filter plate 206 for secondary filtration. After filtration, the clean rainwater flows by gravity to the bottom of the diversion pipe 202 and then into the water inlet pipe 1, and the filtered soil remains on the filter plate 206. To prevent the freshly filtered wet soil from slipping, a plurality of slag retaining plates 207 are provided. The slag retaining plates 207 block the soil, allowing the soil to stay on the filter plate 206 for a longer time, so that the moisture in the soil is fully drained. After the soil is completely dry, the electric telescopic rod 208 is first started to drive the slag retaining plate 207 to slide downward, and then the first motor 210 is started to drive the scraper 215 to slide along the filter plate 206 to scrape the dry soil into the slag conveying pipe 201, completing the rainwater filtration and soil treatment process.

[0039] Embodiment 2, according to Figure 2 - Figure 4 As shown, the vegetation slope protection assembly 3 further includes a water diversion trough 301. The water diversion trough 301 is fixedly connected to the outside of the water inlet pipe 1. The water diversion trough 301 is communicated with the water inlet pipe 1. The top of the water diversion trough 301 is fixedly connected to the humus soil trough 302. An isolation plate 303 is arranged inside the humus soil trough 302. The isolation plate 303 is fixedly connected to the fertilizer application pipe 304. A funnel 306 is fixedly connected to the top of the fertilizer application pipe 304. A plurality of distribution pipes 305 are communicated with the outside of the fertilizer application pipe 304. The inside of the fertilizer application pipe 304 is fixedly connected to the slow-release fertilizer box 308. The slow-release fertilizer box 308 is filled with solid fertilizer. A water collection trough 307 is arranged on the top of the slow-release fertilizer box 308. A plurality of water flow grooves are formed on the top of the slow-release fertilizer box 308.

[0040] The effects achieved by the entire Embodiment 2 are as follows: Place plant branches and leaves at the bottom of the partition board 303 to improve the air permeability of the soil and allow rainwater to penetrate more quickly. The plant branches and leaves are buried between the partition board 303 and the humus soil groove 302. After humification, the soil here will form an aggregate structure. The aggregate structure can make the soil aerated and permeable, supply oxygen to the roots of green plants, help the roots grow, good water permeability can also avoid waterlogging, and the soil's water and fertilizer retention capacity will also become stronger. Excess rainwater passes through the holes in the partition board 303 and the humus soil groove 302, seeps into the water diversion groove 301, and then flows into the water pipe 1 and is discharged. At the same time, when rainwater flows into the fertilizer application pipe 304 through the funnel 306, it is blocked by the water collection tank 307 and flows on the top of the water collection tank 307. Then, through the pipeline on the water collection tank 307, it flows concentratedly to the surface of the slow-release fertilizer tank 308. Finally, the rainwater flows along the flow groove on the surface of the slow-release fertilizer tank 308 to the solid fertilizer in the slow-release fertilizer tank 308, washing down some substances on the surface of the solid fertilizer to form fertilizer water. When there is too much fertilizer water in the fertilizer application pipe 304, it automatically sends the fertilizer water to different soil layers through the multi-layer distribution pipe 305 outside the fertilizer application pipe 304 to evenly fertilize the soil in different soil layers.

[0041] Embodiment 3, according to Figure 4 - Figure 8 As shown in the figure, the muck recycling component 4 further includes a second motor 403. The second motor 403 is fixedly connected to the outside of the screw conveyor 402. The screw conveyor 402 is rotatably connected to the inside of the muck conveying pipe 201. The outer dimension of the screw conveyor 402 is smaller than the inner dimension of the muck conveying pipe 201. The outer cross-sectional area of the slag blocking plate 207 is smaller than the area of the slideway opened on the inner side of the filter plate 206. The filter plate 206 is slidably connected to the slag blocking plate 207 through the slideway opened on the inner side. An upper transmission groove 404 is opened on the inner side of one end of the screw conveyor 402. A transmission belt 405 is sleeved on the inner side of the upper transmission groove 404. The other end of the transmission belt 405 is sleeved with a lower transmission groove 406 on the inner side. A lower transmission wheel 407 is fixedly connected to the outside of the lower transmission groove 406. The outside of the lower transmission wheel 407 is in transmission connection with the conveyor belt 408. The other end of the conveyor belt 408 is sleeved with an upper transmission wheel 409. The outside of the upper transmission wheel 409 is rotatably connected to a bracket 410. The bracket 410 is threadedly connected to the ground through bolts. A protective cover 401 is sleeved on the outside of the lower transmission wheel 407 and the lower transmission wheel 407. A connecting plate is fixedly connected to the outside of the protective cover 401. The connecting plate is rotatably connected to the lower transmission wheel 407. Anti-slip layers are provided on the surfaces of the upper transmission groove 404 and the lower transmission groove 406.

[0042] The effect achieved by the entire Embodiment 3 is as follows: When there is a lot of soil accumulated in the muck conveying pipe 201, in order to reuse this soil, the second motor 403 is started. The motor drives the screw conveyor 402 to rotate. The screw conveyor 402 pushes the soil accumulated in the pipe outwards. The pushed-out soil falls onto the conveyor belt 408. At the same time, because the second motor 403 is rotating, the transmission belt 405 cooperates with the upper transmission groove 404 and the lower transmission groove 406 to drive the fixed lower transmission wheel 407 to rotate as well. The conveyor belt 408 runs synchronously to transport the soil to the ground. The fertility of the collected soil is relatively weak. Therefore, after piling it on the ground, an appropriate amount of fertilizer is added for composting to restore the fertility of the soil for future use.

[0043] The working principle of the entire device is as follows: This device is pre-buried under the soil area to be protected. When encountering natural rainfall, the turf planted in the vegetation trough 204 plays a buffering role, blocking the direct impact of rainwater on the soil surface and reducing the risk of the soil being scattered by rain erosion. When the rainfall is relatively large, causing the humidity of the deep soil to reach the saturation state and unable to absorb water anymore, and the humidity of the surface soil is also saturated, at this time, the excess rainwater will accumulate on the soil surface. The large amount of accumulated water soaking for a long time softens the surface soil, and it is prone to erosion under the action of water flow. In this situation, the vegetation trough 204 separates the surface soil from the deep soil by itself. After the surface soil absorbs water and reaches saturation, the rainwater penetrates through the surface soil in the vegetation trough 204, and then flows into the inside of the shunt pipe 202 through the filter holes opened on the filter trough 203 and the shunt pipe 202 to complete the preliminary filtration. The rainwater after the initial filtration then continues to seep downward along the shunt pipe 202 and falls from its top onto the filter plate 206 below for secondary filtration. At this stage, the purified flowable liquid falls to the bottom of the shunt pipe 202 under the action of gravity and flows into the drain pipe 1. At the same time, the soil particles blocked by the filter plate 206 during the filtration process cannot penetrate the filter plate 206 and thus remain on its surface. Since the just-filtered and water-saturated soil particles are prone to sliding, the device forms a limit through multiple slag blocking plates 207 to prevent the soil from sliding, ensuring that the residence time of the soil on the filter plate 206 is extended so that the water contained in it can be fully drained until the soil is completely dry. Then, the electric telescopic rod 208 is started to drive the slag blocking plate 207 to slide downward, and then the first motor 210 is started to drive the scraper 215 to closely adhere to the filter plate 206. Under the push of the scraper 215, the dry soil is scraped off the filter plate 206 and enters the muck conveying pipe 201.

[0044] In order to maximize the efficiency and effect of preventing soil and water loss, while the sod protects the surface of the soil, by planting green plants with relatively developed root systems in the humus soil tank 302, the maintenance and reinforcement of the deep soil are increased. Plant branches and leaves are added to the bottom of the isolation board 303 to increase the air permeability of the soil, so that the rainwater increases the infiltration efficiency. When the plant branches and leaves buried between the isolation board 303 and the humus soil tank 302 undergo a humification reaction, the soil here forms an aggregate structure. The aggregate structure can increase the air permeability and water permeability of the soil, provide oxygen for the roots of the green plants and promote the growth of the roots. Its good water permeability can also avoid waterlogging and improve the water and fertilizer retention capacity of the soil. Excessive rainwater penetrates through the holes in the isolation board 303 and the humus soil tank 302 into the water diversion tank 301 and flows out through the water pipe 1. At the same time, when the rainwater enters the fertilizer application pipe 304 through the funnel 306, it is blocked by the water collection tank 307 and flows on its top surface. Then, the rainwater is guided and concentrated through the pipeline on the water collection tank 307 to the surface of the slow-release fertilizer tank 308. Finally, the rainwater flows through the flow groove on the surface of the slow-release fertilizer tank 308 to the solid fertilizer inside the slow-release fertilizer tank 308. At this time, the rainwater washes away part of the fertilizer substances on the surface of the solid fertilizer to form fertilizer water. When there is too much fertilizer water in the fertilizer application pipe 304, the fertilizer water flows out through the multi-layer distribution pipes 305 outside the fertilizer application pipe 304 to different soil layers, and uniformly fertilizes the soil in different soil layers, further increasing the fertility of the soil in the humus soil tank 302.

[0045] When there is too much soil accumulated inside the muck conveyor pipe 201, in order to make the soil reusable, the second motor 403 drives the screw conveyor 402 to rotate. When the screw conveyor 402 rotates, it takes out the soil accumulated inside the muck conveyor pipe 201. At this time, the taken-out soil falls on the conveyor belt 408. While the second motor 403 rotates, through the transmission between the transmission belt 405 and the upper transmission groove 404 and the lower transmission groove 406, the lower transmission wheel 407 fixed thereto is driven to rotate. At this time, the conveyor belt 408 runs synchronously to drive the soil on it to the ground. Since the soil collected in this way is all affected by water infiltration and scouring, its fertility is weak. Therefore, the soil is piled up on the ground and fertilizer is added to compost it for subsequent use.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
