TECHNICAL FIELD
[0001] The utility model relates to the technical field of water and soil conservation, and specifically relates to a slope drainage structure for water and soil conservation. BACKGROUND
[0002] Water and soil conservation refers to the prevention and control measures taken to prevent and control water and soil loss caused by natural factors and human activities,
[0003] The existing disclosure No. CN217998110U discloses a greening structure for slope water and soil conservation, which solves the problem of low stability of the existing slope surface caused by water erosion and is prone to water and soil loss. The greening structure includes a slope body, a water collecting ditch is arranged at the middle section of the slope body, a filter structure is arranged inside the water collecting ditch, a drainage ditch is arranged at the slope foot of the slope body, a drainage pipe is connected to the bottom of the water collecting ditch in an array manner, the other end of the drainage pipe is connected to the drainage ditch, a retaining frame is arranged on the slope surface of the slope body from the top to the foot in an array manner, a plurality of greening frames and a protective plate fixed to the side wall of the greening frame are arranged inside the retaining frame, a root plant is planted in the greening frame, and part of the retaining frame is connected to the drainage ditch.
[0004] In the current practice of slope water and soil conservation, people usually take a series of measures to achieve the purpose, including setting up drainage ditches and adopting a square grid planting pattern. The main function of the drainage ditch is to effectively guide and discharge surface water, and the purpose of planting is to reinforce the soil through the root system to prevent soil loss. However, in actual operation, the height of the drainage ditch is often set too low. The original intention of such design is to collect more surface water, but when a large amount of surface water flows into the drainage ditch, the slope surface will also be in contact with too much water. In this case, the surface water may cause erosion of the slope, thereby weakening the role of the drainage ditch in water and soil conservation. Therefore, although the drainage ditch is set up to prevent water and soil loss, it does not completely solve the problem of slope erosion. In view of this problem, the above-mentioned slope water and soil conservation greening structure is proposed. This structure sets a water collecting ditch in the middle of the slope to reduce the direct erosion of surface water on the slope. However, this design also has defects because the water collecting ditch is located in the middle of the slope, and the surface water will still erode at least half of the slope. With the passage of time, the soil on this half of the slope will gradually be lost due to continuous erosion, eventually leading to water and soil being washed into the water collecting ditch, which not only affects the stability of the slope, but also may have a negative impact on the drainage function of the water collecting ditch.
[0005] Therefore, those skilled in the art have provided a slope drainage structure for soil and water conservation to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this utility model is to provide a slope drainage structure for soil and water conservation, so as to solve the problem that the existing slope drainage structures mentioned in the background art are not conducive to solving the problem of slope erosion.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A slope drainage structure for soil and water conservation includes: a slope, the surface of which is provided with slope grids, and a water interception ditch is fixedly provided above the slope grids. A front wall is integrally provided on the front side of the water interception ditch. Side slopes are provided on the left and right sides of the slope. A drainage ditch is provided on the surface of the side slopes. A step is integrally provided on the surface of the drainage ditch. A ground ditch is provided at the lower end of the drainage ditch. A planting grid is provided on the outer side of the drainage ditch.
[0009] As a further improvement of this utility model: the front wall of the intercepting ditch is higher than the rear wall of the intercepting ditch, and the intercepting ditch and the drainage ditch are interconnected.
[0010] As a further improvement of this utility model: the cross-section of the drainage ditch is stepped, and the lower end of the drainage ditch is connected to the ground ditch.
[0011] As a further improvement of this utility model: a water diversion ditch is provided at the top of the slope, and the external structure of the water diversion ditch is V-shaped.
[0012] As a further improvement of this utility model: the outlet end of the water diversion ditch is provided with a wedge, and the lower end of the wedge is connected to a fan-shaped opening.
[0013] As a further embodiment of this utility model: the water diversion channel is interconnected through the wedge-shaped opening and the fan-shaped opening, and the lower end of the fan-shaped opening is interconnected with the intercepting ditch, and the external structure of the fan-shaped opening is fan-shaped.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. Side slopes were constructed on both sides of the slope, and drainage ditches were laid on the surface of these side slopes to ensure smooth drainage of water. At the same time, intercepting ditches were specially constructed at appropriate locations on the slope. These intercepting ditches were designed to be relatively high to effectively intercept surface water at higher points on the slope. The purpose of this design is to prevent excessive surface water erosion of the slope, thereby maintaining the stability of the slope's soil structure and preventing soil loss. To further improve the interception effect, the front wall of the intercepting ditch was designed to be higher than the rear wall, which can more effectively intercept surface water and prevent it from flowing out of the intercepting ditch and into the slope. In addition, both ends of the intercepting ditch are connected to the drainage ditch to ensure that the intercepted surface water can flow smoothly into the drainage ditch. Through the guidance of the drainage ditch, the surface water can be diverted downward and discharged into a safe area, thereby effectively avoiding the slope and reducing potential damage to the slope.
[0016] 2. The main function of the intercepting ditch is to intercept surface water flowing down from the upper slope, thereby preventing the water flow from directly eroding the slope surface and protecting the slope's stability. In addition, longitudinal drainage ditches are set on the side slope of the slope. The function of these drainage ditches is to guide surface water to a predetermined safe discharge point, ensuring that the water flow will not damage the slope. To further optimize the drainage effect, a stepped structure is designed inside the drainage ditch. This design helps to slow down the water flow. At the same time, the drainage ditch adopts a stepped structure to adapt to the drainage needs under different terrain conditions. On the outside of the drainage ditch, special planting grids for vegetation are reserved. This not only helps to stabilize the soil, but also allows the vegetation to further absorb surface water. The stepped drainage ditch design can more effectively slow down the water flow and prevent the drainage ditch from being eroded by excessively rapid water flow, ensuring the long-term stability of the drainage system and the safety of the slope.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figs. 1-4 This utility model provides a slope drainage structure for soil and water conservation, including: a slope 1, a slope grid 6 on the surface of the slope 1, a water interception ditch 5 fixedly opened above the slope grid 6, a water diversion ditch 2 on the top of the slope 1, the external structure of the water diversion ditch 2 being "V" shaped, a wedge 3 at the outlet end of the water diversion ditch 2, and a fan-shaped opening 4 connected to the lower end of the wedge 3, the water diversion ditch 2 being interconnected with the fan-shaped opening 4, and the lower end of the fan-shaped opening 4 being interconnected with the water interception ditch 5, the external structure of the fan-shaped opening 4 being fan-shaped;
[0024] Specifically, the "V"-shaped water diversion ditch 2 designed and installed on slope 1 has the main function of effectively guiding the surface water collected from both sides of slope 1 to the front end of the water diversion ditch 2. The front end of the water diversion ditch 2 is connected to a wedge-shaped structure, which is called the wedge opening 3. After the surface water flows into the wedge opening 3, the surface water will continue to flow along the wedge opening 3 to the fan-shaped opening 4 below. The design of the fan-shaped opening 4 is that the lower opening is relatively large, while the upper opening is relatively small. This design utilizes the characteristics of the fan-shaped structure to evenly distribute the surface water, so that the surface water can gradually disperse along the fan-shaped surface of the fan opening 4. This dispersion method effectively avoids the surface water from being too concentrated, thereby preventing the water flow from eroding the intercepting ditch 5 and ensuring the stability and safety of slope 1.
[0025] The front wall 12 is integrated on the front side of the intercepting ditch 5, the side slopes 7 are provided on the left and right sides of the slope 1, the drainage ditch 8 is provided on the surface of the side slope 7, the steps 11 are integrated on the surface of the drainage ditch 8, the lower end of the drainage ditch 8 is provided with a ditch 9, and the outer side of the drainage ditch 8 is provided with a planting grid 10.
[0026] The front wall 12 of the intercepting ditch 5 is higher than the rear wall of the intercepting ditch 5, and the intercepting ditch 5 and the drainage ditch 8 are interconnected. The cross-section of the drainage ditch 8 is stepped 11, and the lower end of the drainage ditch 8 is interconnected with the ground ditch 9.
[0027] Specifically, the intercepting ditch 5 is located at the top of the slope 1. Its main function is to intercept surface water flow at higher elevations. The front wall 12 of this ditch is designed to be higher than the rear wall, so that when surface water flows out due to rainfall or other reasons, the front wall 12 can effectively block the overflowing water, ensuring that more surface water can flow smoothly into the intercepting ditch 5. Once the surface water enters the intercepting ditch 5, it will flow along the ditch to the pre-designed drainage ditches 8 on both sides. The drainage ditches 8 have a stepped structure 11 inside. The purpose of this stepped drainage ditch 8 is to slow down the water flow. To effectively prevent water flow from scouring and eroding the bottom of drainage ditch 8, surface water, after being slowed down by the stepped drainage ditch 8, will continue to flow down along the drainage ditch 8 and eventually flow into the ditch 9. The function of the ditch 9 is to safely guide the collected water to the predetermined discharge point to ensure that the water flow will not cause damage to the surrounding environment. In addition, planting grids 10 are specially set up on the outside of drainage ditch 8. Various vegetation is planted in these planting grids 10. These vegetation not only beautifies the environment, but more importantly, they can absorb and utilize the water in the water flow, further enhancing the stability of slope 1 and preventing soil erosion.
[0028] The working principle of this utility model is as follows:
[0029] In using this invention, firstly, surface water is guided to the front end of the irrigation ditch 2 at the top of the slope 1. As the water flows into the wedge 3, due to the shape design of the wedge 3, the water is smoothly guided to the fan-shaped opening 4 below. The design of the fan-shaped opening 4 allows the water flow to be dispersed, avoiding the scouring problem caused by the water flow being too concentrated. Subsequently, the water flow dispersed by the fan-shaped opening 4 flows smoothly into the intercepting ditch 5. The front wall 12 of the intercepting ditch 5 is higher than the rear wall, effectively blocking the water flow from overflowing and ensuring that the water flow can completely flow into the drainage ditch 8. The stepped design 11 inside the drainage ditch 8 further slows down the water flow speed and prevents scouring and erosion of the bottom of the drainage ditch 8. Finally, the water flow is guided by the drainage ditch 8 and safely flows into the ditch 9, which guides the water flow to the predetermined discharge point. Throughout the process, the vegetation in the planting grid 10 absorbs and utilizes some of the water, enhancing the stability of the slope 1 and effectively preventing soil erosion.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
