Description
Technical Field
[0001] This utility model relates to the field of drainage and diversion technology, and in particular to a drainage and diversion device for high slopes. Background Technology
[0002] During slope construction, the drainage system of high slopes is a key facility to ensure slope stability and project safety. Affected by factors such as rainfall infiltration, groundwater activity and surface runoff, high slopes are prone to water accumulation. If drainage is not smooth, it may lead to soil saturation, reduced strength, or even induce geological disasters such as landslides.
[0003] Traditional drainage schemes for high slopes mainly include surface drainage ditches and blind drains, which have many limitations. For example, surface drainage ditches are easily affected by the accumulation of fallen leaves, silt, and debris, leading to frequent blockages. Furthermore, long-term water flow can damage the structure, reduce drainage efficiency, and increase maintenance costs. Although blind drains can divert groundwater through gravel layers, their simple structure makes them difficult to cope with sudden rainstorms or large-volume runoff, and they are prone to local water accumulation or overflow, failing to guarantee the stability of high slopes. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a drainage and diversion device for high slopes, which is mainly used for drainage and diversion of high slopes, so as to make the water flow in a predetermined direction, cope with sudden rainstorms or large-volume runoff, avoid disorderly water flow erosion of the slope, and reduce the erosion of the slope soil.
[0005] This utility model discloses a high slope drainage and diversion device, including a slope body, which includes a slope top, a slope surface, and a slope bottom. A water storage tank is provided at the slope top, and an inclined bottom plate inclined towards the slope surface is provided at the bottom of the water storage tank. A drainage ditch is provided at the slope bottom, and a protective baffle is provided on the side of the drainage ditch away from the slope top, the protective baffle being higher than the side of the drainage ditch closer to the slope top. A diversion channel is provided on the slope surface along the inclined direction of the slope surface, the diversion channel including two intersecting drainage channels. One end of the drainage channel is connected to the water storage tank, and the bottom of the drainage channel is located below the inclined bottom plate. The other end of the drainage channel is connected to the drainage ditch. A water collection tank parallel to the water storage tank is also provided on the slope surface. The lower end of the diversion channel above the water collection tank is connected to the water collection tank, and the upper end of the diversion channel below the water collection tank is connected to the water collection tank.
[0006] Furthermore, the top of the water storage tank and the top of the water collection tank are both equipped with filter screens, and a protective net is provided on the slope surface above the flow guide channel.
[0007] Furthermore, the slope surface is also provided with blocking piles located on the side of the water collection trough near the bottom of the slope. The blocking piles include vertical piles and connecting plates. Multiple vertical piles are spaced apart on the slope surface between two intersecting drainage ditches. The connecting plates are horizontally arranged on the vertical piles and fixedly connected to each vertical pile.
[0008] As a preferred embodiment, the connecting plates are multiple and spaced apart on the vertical pile along the height direction of the vertical pile.
[0009] Furthermore, the protective baffle is provided with columns at both ends, and a net is provided between the two columns to prevent falling off.
[0010] As a preferred embodiment, each of the columns is provided with a warning reflector on its side wall.
[0011] Furthermore, the drainage ditch is equipped with anti-slip piles, and a plurality of anti-slip piles are spaced apart along the length of the drainage ditch, with the bottom of the anti-slip piles located in the stratum below the drainage ditch.
[0012] Furthermore, the drainage ditch has a V-shaped cross-section.
[0013] The beneficial effects of this utility model are as follows: This high slope drainage and diversion device achieves segmented collection of water flow on the slope by setting up a water storage tank at the top of the slope, a water collection tank on the slope surface, and a drainage ditch at the bottom of the slope. This helps to cope with sudden rainstorms or large-volume runoff and prevents excessive water flow from directly scouring the slope surface. By setting up a diversion channel on the slope surface between the water storage tank, the water collection tank, and the drainage ditch, the water in the water storage tank is guided to the water collection tank, and then the water in the water collection tank is guided to the drainage ditch. At the same time, the water flow on the slope surface also collects into the intersecting drainage channels, and finally into the drainage ditch for drainage. This allows the water flow to flow in a predetermined direction, reducing the disorderly scouring of the slope by the water flow, reducing the erosion of the slope soil by the water flow, and ensuring the stability of the slope.

Detailed Implementation
[0019] The present invention will be further described below.
[0020] This utility model provides a high slope drainage and diversion device, mainly used for high slope drainage and diversion. It includes a slope body 11, which comprises a slope top 111, a slope surface 112, and a slope bottom 113. The slope top 111 is provided with a water storage tank 12, and the bottom of the water storage tank 12 is provided with an inclined bottom plate 13 inclined towards the slope surface 112. The slope bottom 113 is provided with a drainage ditch 16, and a protective baffle 17 is provided on the side of the drainage ditch 16 away from the slope top 111, the protective baffle 17 being higher than the side of the drainage ditch 16 closest to the slope top 111. The slope surface 112 is provided with... A flow channel 14 is provided along the inclined direction of the slope surface 112. The flow channel 14 includes two intersecting drainage channels 141. One end of the drainage channel 141 is connected to the water storage tank 12 and the bottom of the drainage channel 141 is located below the inclined bottom plate 13. The other end of the drainage channel 141 is connected to the drainage ditch 16. A water collection tank 15 parallel to the water storage tank 12 is also provided on the slope surface 112. The lower end of the flow channel 14 located above the water collection tank 15 is connected to the water collection tank 15, and the upper end of the flow channel 14 located below the water collection tank 15 is connected to the water collection tank 15.
[0021] like Figures 1-4As shown, the high slope drainage and diversion device includes a slope body 11. A water storage tank 12 is provided at the top 111 of the slope body 11. The bottom of the water storage tank 12 is provided with an inclined bottom plate 13 that slopes towards the slope surface 112, so as to guide the water stored in the water storage tank 12 to flow and discharge along the inclined direction of the slope surface 112, preventing rainwater from accumulating at the bottom of the water storage tank 12, and allowing it to flow along the inclined bottom plate 13 at the bottom of the water storage tank 12 to the drainage ditch 141 connected thereto, ensuring the normal water storage and drainage function of the water storage tank 12 and improving drainage efficiency. A drainage ditch 16 is provided at the bottom 113 of the slope, which is used to collect the water flow on the slope and guide it to a river or In the subsequent water treatment system, a protective baffle 17 is provided on the side of the drainage ditch 16 away from the top of the slope 111. The height of the protective baffle 17 is higher than the side of the drainage ditch 16 near the top of the slope 111 to prevent water in the drainage ditch 16 from overflowing, avoid water flow erosion of the slope bottom 113, protect the structural stability of the slope bottom 113, and also guide the water flow in the drainage ditch 16. A flow guiding channel 14 is provided on the slope surface 112. The flow guiding channel 14 is set along the inclined direction of the slope surface 112 so that the water flow on the slope surface 112 can be collected in the flow guiding channel 14 for drainage. The flow guiding channel 14 includes two intersecting drainage channels 141. Specifically, two drainage channels 141 are arranged in a diamond shape on the slope surface 112. This arrangement increases the drainage path and improves drainage capacity, ensuring that rainwater can be quickly discharged to the drainage ditch 16 from different directions, reducing localized water accumulation on the slope surface 112. One end of each drainage channel 141 is connected to a water storage tank 12, and the bottom of the drainage channel 141 is located below the inclined base plate 13. This allows water in the water storage tank 12 to be completely guided along the drainage channel 141 to the drainage ditch 16 at the bottom of the slope 113, preventing disorderly water flow from eroding the slope and reducing soil erosion. A water collection trough 15, parallel to the water storage tank 12, is also provided on the slope surface 112. The lower end of the guide channel 14 above 15 is connected to the water collection trough 15, and the upper end of the guide channel 14 below the water collection trough 15 is connected to the water collection trough 15. By setting the water collection trough 15 in the middle of the slope surface 112, the water collection trough 15 is used to realize the secondary collection and distribution of water flow on the slope surface 112, disperse the accumulation of water flow, so that rainwater can flow into the guide channel 14 more evenly and efficiently, further improving drainage efficiency to adapt to the situation of larger water flow or abundant rain during the rainy season, while enhancing the stability of the drainage system of the slope surface 112; multiple water collection troughs 15 can be set at intervals on the slope surface 112 to adapt to slopes with different rainfall intensities and water flow rates.Meanwhile, a corresponding inclined base plate 13 can also be provided at the bottom of the water collection trough 15. The inclined direction of the inclined base plate 13 is also set along the inclined direction of the slope surface 112. The bottom of the drainage ditch 141 connected to the water collection trough 15 is lower than the inclined base plate 13 located in the water collection trough 15, so that the water in the water collection trough 15 can flow completely into the drainage ditch 16 along the drainage ditch 141. This high slope drainage and diversion device achieves the purpose of segmented collection and graded discharge of water flow on the slope by setting up a water storage tank 12 at the top 111 of the slope, a water collection tank 15 on the slope surface 112, and a drainage ditch 16 at the bottom 113 of the slope. This is to cope with sudden rainstorms or large-volume runoff and prevent excessive water flow from directly scouring the slope surface 112. By setting up a diversion channel 14 on the slope surface 112 between the water storage tank 12, the water collection tank 15, and the drainage ditch 16, the water in the water storage tank 12 is guided along the setting direction of the drainage ditch 141 to the water collection tank 15, and then the water in the water collection tank 16 is discharged into the drainage ditch 16. Water within section 5 is guided into drainage ditch 16, thus directing the water flow. Simultaneously, water flowing from slope surface 112 also converges into the intersecting drainage channels 141, ultimately draining into drainage ditch 16. This ensures the water flows in a predetermined direction, reducing disorderly erosion of the slope and minimizing soil erosion, thereby guaranteeing slope stability. The orientation of drainage channels 141 can be precisely planned based on the topography, water flow direction, and engineering requirements of the high slope, ensuring the water flows in a predetermined direction, preventing disorderly erosion of the slope, and reducing soil erosion.
[0022] To prevent the accumulation of fallen leaves, mud, and debris from clogging the flow channel 14, such as... Figure 1 , Figure 3As shown, filter screens 21 are provided on the top of the water storage tank 12 and the top of the water collection tank 15, and a protective net 31 is provided on the slope surface 112 above the diversion channel 14. The filter screens 21 are installed on the top of the water storage tank 12 and the water collection tank 15 and are arranged in a covering manner. During operation, when encountering strong winds or the rainy season, the filter screens 21 can filter out larger impurities in the water flow, preventing fallen leaves and branches from falling into the water storage tank 12 and the water collection tank 15, and preventing the water flow from the water storage tank 12 or the water collection tank 15 to the drainage ditch 141, thus preventing blockage of the drainage ditch 141, thereby ensuring the normal operation of the diversion channel 14 and the entire drainage diversion device. The protective net 31 is installed above the diversion channel 14, perpendicular to the slope surface 112. The support piles 32 are installed above the drainage channel 14, covering the entire slope surface 112 of the drainage channel 14. This prevents fallen leaves and soil from falling into the drainage ditch 141, causing blockage and affecting the drainage channel 14's flow guidance effect. The protective net 31 can effectively withstand large external forces and water flow impacts, effectively intercepting larger debris and preventing leaves and branches from entering the drainage system and clogging the drainage channel 14. The filter 21 can be made of metal, which is more robust and can prevent heavy objects from damaging it. It can effectively intercept impurities and prevent them from entering the drainage channel 14 and causing blockage, ensuring the smooth operation of the entire drainage diversion device.
[0023] To prevent objects on the slope from rolling down the slope into the drainage ditch 16 or accumulating on the diversion channel 14, such as Figure 1 , Figure 4As shown, the slope surface 112 is also provided with blocking piles 51 located on the side of the water collection trough 15 near the bottom of the slope 113. Each blocking pile 51 includes a vertical pile 511 and a connecting plate 512. Multiple vertical piles 511 are spaced apart on the slope surface 112 between two intersecting drainage ditches 141. The connecting plate 512 is horizontally positioned on the vertical piles 511 and fixedly connected to each vertical pile 511. By providing blocking piles 51 on the slope surface 112, and with these blocking piles 51 located on the side of the water collection trough 15 near the bottom of the slope 113, the slope is effectively protected. This is to intercept falling soil, rocks, dead branches, and other objects from above the slope and control them in the upper part of the slope, preventing them from falling into the drainage ditch 16 below the slope and affecting the drainage effect of the drainage ditch 16; the blocking pile 51 includes vertical piles 511 and connecting plates 512. Multiple vertical piles 511 are spaced apart on the slope surface 112 located between two intersecting drainage ditches 141, which does not affect the normal use of the water collection trough 15 and the drainage ditch 141, and can also enhance the stability of the slope surface 112 and prevent soil on the slope surface 112 from falling. By controlling the spacing between adjacent vertical piles 511, objects rolling down the slope can be effectively intercepted, ensuring the normal use of the drainage ditch 16 and the drainage channel 141 located below the blocking piles 51. Furthermore, multiple vertical piles 511 are connected into a whole by connecting plates 512, improving the overall strength and stability of the blocking piles 51, while ensuring the blocking piles 51's effectiveness in intercepting falling objects. As a preferred method, to ensure that the blocking piles 51 can intercept soil and rocks of different sizes, multiple connecting plates 512 are used and arranged vertically. The piles 511 are spaced apart along the height direction on the vertical piles 511. By adding connecting plates 512, the connecting plates 512 are spaced apart along the height direction on the vertical piles 511, reducing the spacing between adjacent connecting plates 512. This ensures that the blocking piles 51 can intercept soil and rocks of different sizes. Furthermore, by adding connecting plates 512, the strength and overall stability of the vertical piles 511 can be improved, further enhancing the impact resistance of the blocking piles 51 and ensuring their interception effect, thereby ensuring the drainage and diversion efficiency of the drainage diversion device.
[0024] To prevent debris and rocks from rolling down the slope and damaging roads, buildings, people, or equipment below, such as... Figure 1 , Figure 4 As shown, the protective baffle 17 has posts 171 at both ends, and a fall-prevention net 61 is provided between the two posts 171. By setting the fall-prevention net 61 between the protective baffles 17, when a large object rolls down, it can be blocked a second time by the fall-prevention net 61, and it can also prevent unauthorized personnel from climbing onto the slope. Through the fall-prevention net 61, it can also effectively intercept rocks rolling down the slope due to weathering, rainwater erosion, earthquakes, etc., and prevent falling rocks from damaging roads, buildings, personnel, and equipment below; furthermore, as Figure 1, Figure 4 As shown, each of the columns 171 is provided with a warning reflector 71 on its side wall; specifically, the warning reflector 71 is located in the middle of the column 171 and is arranged symmetrically. When in operation, the warning reflector 71 can be used to warn personnel and drivers. At night or in low light conditions, it can reflect vehicle lights or other light sources to warn vehicles and pedestrians and avoid safety accidents such as collisions.
[0025] To ensure the stability of the slope and the normal use of drainage ditch 16, such as Figure 1 , Figure 3 As shown, anti-slip piles 41 are installed in the drainage ditch 16. Multiple anti-slip piles 41 are spaced apart along the length of the drainage ditch 16, and the bottom of the anti-slip piles 41 is located in the stratum below the drainage ditch. By inserting the anti-slip piles 41 into the stable stratum below the drainage ditch, the anchoring effect of the stable stratum soil and rock is used to balance the landslide thrust, thereby stabilizing the slope and preventing the drainage ditch 16 from sliding or deforming under the scouring of rainwater, thus ensuring the normal drainage function of the drainage ditch 16. At the same time, because anti-slip piles 41 are installed in the drainage ditch 16, stones and other objects falling from the slope cannot fall into the drainage ditch 16 and cause blockage, thereby ensuring the normal drainage function of the drainage ditch 16.
[0026] To prevent sediment from settling in the drainage ditch 141 and clogging it, thus affecting the flow of water, the drainage ditch 141 has a V-shaped cross-section (not shown in the figure). By designing the cross-section of the drainage ditch 141 as V-shaped, the water flow speed can be increased, allowing the water flowing in the drainage ditch 141 to easily carry the sediment away from the drainage ditch 141 and into the collection tank 15 or drainage ditch 16, thereby reducing the accumulation of sediment in the drainage ditch 141 and improving drainage efficiency.
