DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0040] In the existing slope protection system, when encountering heavy rainfall, a large amount of rainwater can easily penetrate into the slope, and the strong rainstorm water will scour the slope surface, reducing the shear strength of the slope, and eventually catalyze the slope to become unstable.

[0041] To solve the above problems, the main concept adopted in this embodiment is: by providing an overflow plate 5 on one side of the intercepting ditch 2 and a drainage pipe 8 inside the slope, water interception and drainage can be achieved during heavy rains, and the water potential can be buffered to prevent rainwater from eroding and infiltrating the slope.

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods;

[0043] The present invention provides a water conservancy and hydropower engineering slope protection system, comprising a slope body 1, a drainage ditch 2 is provided on the surface of the slope body 1, vegetation layers 3 are provided on both sides of the drainage ditch 2, a drainage ditch 4 is provided at the bottom of the slope body 1, and further comprising:

[0044] Overflow plate 5: The number of the overflow plate 5 is at least one, and the overflow plate 5 is connected to one side of the intercepting ditch 2;

[0045] Spring 6: the spring 6 is located inside the intercepting ditch 2, and the spring 6 is connected to the overflow plate 5;

[0046] Drain hole 7: The drain hole 7 is located inside the intercepting ditch 2 and the number is at least one. A switch door 10 is provided at the mouth of the drain hole 7;

[0047] Drain pipe 8: The drain pipe 8 is located at the bottom of the intercepting ditch 2, one end of the drain pipe 8 is connected to the drain hole 7 and the other end is connected to the drain ditch 4;

[0048] Connecting rod No. 1 9: The connecting rod No. 1 9 is located inside the intercepting ditch 2 , and one end of the connecting rod No. 1 9 is connected to a switch door 10 , and the other end is connected to an overflow plate 5 .

[0049] In order to reduce the flow of surface rainwater into the slope, the present invention provides a drainage ditch 2 on the surface of the slope body 1, a vegetation layer 3 is provided on both sides of the drainage ditch 2, and a drainage ditch 4 is provided at the bottom of the slope body 1. The commonly used drainage ditch 2 is excavated inside the slope body. The drainage ditch 2 designed by the present invention is higher than the slope body 1, and an overflow plate 5 is hinged on one side of the drainage ditch 2, and the number of the overflow plate 5 is at least one; a spring 6 is provided inside the drainage ditch 2, one end of the spring 6 is fixedly connected to the inner wall of the drainage ditch 2, and the other end is fixedly connected to the overflow plate 5. Fixed connection; at least one drainage hole 7 is opened inside the intercepting ditch 2, and a switch door 10 is hinged at the mouth end of the drainage hole 7. A No. 1 connecting rod 9 is hinged on the outer surface of the switch door 10, and the other end of the No. 1 connecting rod 9 is hinged to the overflow plate 5. One end of the drainage hole 7 is fixedly connected to the intercepting ditch 2, and the other end is fixedly connected to a drainage pipe 8. One side of the drainage pipe 8 is fixedly connected to the drainage ditch 4. The present invention combines vegetation and the intercepting ditch 2 to consolidate the soil and drain the slope body 1, thereby preventing a large amount of rainwater from seeping into the slope body.

[0050] The construction of water conservancy and hydropower projects will inevitably have a certain impact on the ecology. The first is the increase in rainfall. The construction of water conservancy facilities will increase the air humidity above the construction site. In heavy rain season, the rainfall is heavy, and rainwater flows into the intercepting ditch 2 along the top of the slope. The present invention sets the intercepting ditch 2 on the surface of the slope body 1. On the one hand, it increases the resistance of rainwater flowing down and slows down the water flow. On the other hand, it can prevent rainwater from directly falling on the vegetation layer 3 from top to bottom, causing the vegetation to be washed away. Due to the construction of water conservancy and hydropower projects, great damage is caused to the ecological environment. In order to reduce soil erosion, grass or turf is artificially planted on the slope body 1. However, these are easily washed away in the early stage of planting, so the intercepting ditch 2 is set on the slope. When heavy rain continues, rainwater impacts the overflow plate 5, causing the overflow plate 5 hinged to one side of the intercepting ditch 2 to rotate. The overflow plate 5 deviates and drives the No. 1 connecting rod 9 hinged to it to rotate, and then the No. 1 connecting rod 9 drives the switch door 10 to open, and the rainwater leaks out through the drainage hole 7, and finally discharged into the drain pipe 8 and flows into the drainage ditch 4. At the same time, the rotation of the overflow plate 5 also diverts the water out of the intercepting ditch 2 to avoid the rainwater only being discharged through the drainage hole 7, resulting in excessive drainage and poor drainage. When the rain becomes less, the overflow plate 5 is no longer subjected to the impact force, and the spring 6 drives the overflow plate 5 to rotate to the initial position.

[0051] As a specific implementation of the present invention, a protection component 11 is provided near one side of the overflow plate 5 , and the number of the protection component 11 is at least one. The protection component 11 provides protection for the vegetation layer 3 .

[0052] In the early stage of vegetation planting, vegetation is easily washed away by rain and is difficult to survive, which damages the ecological protection of the slope and requires ecological engineering to be repaired, wasting a lot of manpower and funds. Therefore, the present invention sets a protective component 11 on one side of the overflow plate 5 to further protect the vegetation.

[0053] As a specific embodiment of the present invention, the protection component 11 includes:

[0054] No. 2 connecting rod 111: one side of the No. 2 connecting rod 111 is connected to the overflow plate 5;

[0055] Slide plate 112: a fixing block 113 is provided on the surface of the slide plate 112, and the fixing block 113 is connected to the second connecting rod 111;

[0056] Base 114: A first slide groove 115 is provided on the surface of the base 114, and at least two second slide grooves 116 are provided at the bottom of the base 114;

[0057] No. 3 connecting rod 117: There are two No. 3 connecting rods 117, one side of which is connected to the No. 1 chute 115;

[0058] Protective plate 118: There are two protective plates 118, one side of which is provided with a fixing plate 119, and the fixing plate 119 is connected to the third connecting rod 117;

[0059] Slider 120 : There are two sliders 120 , and the sliders 120 are slidably connected to the second slide groove 116 .

[0060] As a specific implementation of the present invention, a plastic film 12 is connected to one side of the protection plate 118 and two sides of the base 114 .

[0061] See also Figure 4-6 The protection assembly 11 of the present invention includes a second connecting rod 111, a slide plate 112, a base 114, a third connecting rod 117, a protection plate 118 and a slide block 120. One end of the No. 2 connecting rod 111 is hinged to the overflow plate 5, and a fixed block 113 is fixedly connected to the surface of the slide plate 112, and the other end of the No. 2 connecting rod 111 is hinged to the fixed block 113; a No. 1 slide groove 115 is provided on the surface of the base 114, and at least two No. 2 slide grooves 116 are also provided at the bottom of the base 114; there are two No. 3 connecting rods 117, and one end of the No. 3 connecting rod 117 is hinged to a connecting block, and the connecting block is slidably connected to the No. 1 slide groove 115 and the outer surface of the connecting block is fixedly connected to the slide plate 112; there are two protective plates 118, and a fixed plate 119 is fixedly connected to one side of the protective plate 118, and the fixed plate 119 is hinged to the No. 3 connecting rod 117; there are two sliders 120, one end of which is slidably connected to the No. 2 slide groove 116, and the other end is fixedly connected to the protective plate 118.

[0062] When the protective assembly of the present invention is not attacked by heavy rain, the protective plates 118 on both sides are retracted on the surface of the base 114 and are close to each other in a closed state. When the overflow plate 5 is subjected to the pressure of heavy rain, it rotates, so that the No. 2 connecting rod 111 pushes the fixed block 113 hinged thereto. When the fixed block 113 drives the slide plate 112 to move on the No. 1 slide groove 115 opened on the surface of the base 114, since the slide plate 112 is fixedly connected to the connecting block and the connecting block is hinged to one end of the No. 3 connecting rod 117, when the slide plate 112 moves on the No. 1 slide groove 115, the slide plate 112 drives the No. 3 connecting rod 117 to rotate outward. One end of 117 is hinged to the fixed plate 119 and the fixed plate 119 is fixedly connected to the protective plate 118, so when the No. 3 connecting rod 117 rotates, it pushes the protective plates 118 on both sides away from each other and thus opens, and the protective plates 118 are fixedly connected to the slider 120. When the protective plate 118 is opened, it drives the slider 120 to move in the No. 2 slide groove 116, ensuring the deployment path of the protective plate 118. Since the protection range of the protective plate 118 is limited, a plastic film 12 is connected to both sides of the base 114 on one side of the protective plate 118. When the protective plate 118 is opened, the plastic film also unfolds, thereby reducing the erosion of grass by rainwater to the greatest extent.

[0063] As a specific implementation of the present invention, drainage holes 13 are evenly distributed on both sides of the intercepting ditch 2.

[0064] When heavy rain pours down, in order to promote smooth drainage, drainage holes 13 are evenly distributed on both sides of the intercepting ditch 2. Part of the rainwater flows into the drainage holes 7 and is discharged to the drainage pipe 8, and part of the rainwater flows through the drainage holes 13 layer by layer into the drainage ditch 4 at the bottom of the slope.

[0065] As a specific implementation of the present invention, a filter screen is provided at the mouth of the drain hole 7 .

[0066] When rainwater is discharged into the drainage hole 7, sand and soil on the surface of the slope will be brought in. In order to prevent the sand and soil from clogging the drainage hole 7, a filter screen is arranged at the mouth of the drainage hole 7 to ensure smooth drainage.

[0067] As a specific implementation of the present invention, a concrete protective layer is sprayed on the surface of the intercepting ditch 2.

[0068] In order to reduce the surface runoff from entering the slope and reduce the infiltration of rainwater, a concrete protective layer is sprayed on the surface of the intercepting ditch 2, which also improves the surface strength of the intercepting ditch 2 and extends the service life of the intercepting ditch 2.

[0069] As a specific implementation of the present invention, a breeding pen 14 is provided inside the vegetation layer 3 , the number of the breeding pen 14 is at least one, and grass is provided inside the breeding pen 14 .

[0070] As a specific implementation of the present invention, the bottom of the breeding pen 14 is evenly provided with small through holes.

[0071] In the construction of water conservancy and hydropower projects, groundwater is also one of the important factors affecting the stability of the slope. Vegetation can not only protect the slope but also not affect the discharge of groundwater, thus protecting the entire ecological environment. However, vegetation must have suitable soil and fertilizer for planting. The present invention is provided with a vegetation breeding fence 14, in which vegetation grows. Fertilizer and soil can be laid in the breeding fence 14 for grass growth. At the same time, small through holes are provided at the bottom of the breeding fence 14 to promote the breathing of grass and the discharge of surface water.

[0072] As a specific implementation of the present invention, the material of the spring 6 is ultra-high strength steel.

[0073] In order to ensure the safety of the present invention in practice, the material of the spring 6 is set to be ultra-high strength steel, which has high strength and good toughness, and can ensure normal use in heavy rain.

[0074] The specific workflow is as follows:

[0075] In order to reduce the flow of surface rainwater into the slope, the present invention provides a drainage ditch 2 on the surface of the slope body 1, and a vegetation layer 3 is provided on both sides of the drainage ditch 2. The bottom of the slope body is covered with a drainage ditch 4. The commonly used drainage ditch 2 is excavated inside the slope body. The drainage ditch 2 designed by the present invention is higher than the slope body 1. An overflow plate 5 is hinged on one side of the drainage ditch 2, and the number of the overflow plate 5 is at least one; a spring 6 is provided inside the drainage ditch 2, one end of the spring 6 is fixedly connected to the inner wall of the drainage ditch 2, and the other end is fixed to the overflow plate 5. Connection; at least one drainage hole 7 is opened inside the intercepting ditch 2, and a switch door 10 is hinged at the mouth end of the drainage hole 7. A No. 1 connecting rod 9 is hinged on the outer surface of the switch door 10, and the other end of the No. 1 connecting rod 9 is hinged to the overflow plate 5. One end of the drainage hole 7 is fixedly connected to the intercepting ditch 2, and the other end is fixedly connected to a drainage pipe 8. One side of the drainage pipe 8 is fixedly connected to the drainage ditch 4. The present invention combines vegetation and the intercepting ditch 2 to consolidate the soil and drain the slope body 1, thereby preventing a large amount of rainwater from seeping into the slope body.

[0076] The construction of water conservancy and hydropower projects will inevitably have a certain impact on the ecology. The first is the increase in rainfall. The construction of water conservancy facilities will increase the air humidity above the construction site. In heavy rain season, the rainfall is heavy, and rainwater flows into the intercepting ditch 2 along the top of the slope. The present invention sets the intercepting ditch 2 on the surface of the slope to increase the resistance of rainwater flowing down and slow down the water flow. On the other hand, it can prevent rainwater from directly falling on the vegetation layer 3 from top to bottom, causing the vegetation to be washed away. Due to the construction of water conservancy and hydropower projects, great damage is caused to the ecological environment. In order to reduce soil erosion, grass or turf are artificially planted on the slope, but these are easily washed away in the early stage of planting, so the intercepting ditch 2 is set on the slope. When heavy rain continues, rainwater impacts the overflow plate 5, causing the overflow plate 5 hinged to one side of the intercepting ditch 2 to rotate. The overflow plate 5 deviates and drives the No. 1 connecting rod 9 hinged to it to rotate, and then the No. 1 connecting rod 9 drives the switch door 10 to open, and the rainwater leaks out through the drainage hole 7, and finally discharged into the drain pipe 8 and flows into the drainage ditch 4. At the same time, the rotation of the overflow plate 5 also diverts the water out of the intercepting ditch 2 to avoid the rainwater only being discharged through the drainage hole 7, resulting in excessive drainage and poor drainage. When the rain becomes less, the overflow plate 5 is no longer subjected to the impact force, and the spring 6 drives the overflow plate 5 to rotate to the initial position.

[0077] In the early stage of vegetation planting, vegetation is easily washed away by rain and is difficult to survive, which damages the ecological protection of the slope and requires ecological engineering to be repaired, wasting a lot of manpower and funds. Therefore, the present invention sets a protective component 11 on one side of the overflow plate 5 to further protect the vegetation.

[0078] See also Figure 4-6 The protection assembly 11 of the present invention includes a second connecting rod 111, a slide plate 112, a base 114, a third connecting rod 117, a protection plate 118 and a slide block 120. One end of the No. 2 connecting rod 111 is hinged to the overflow plate 5, and a fixed block 113 is fixedly connected to the surface of the slide plate 112, and the other end of the No. 2 connecting rod 111 is hinged to the fixed block 113; a No. 1 slide groove 115 is provided on the surface of the base 114, and at least two No. 2 slide grooves 116 are also provided at the bottom of the base 114; there are two No. 3 connecting rods 117, and one end of the No. 3 connecting rod 117 is hinged to a connecting block, and the connecting block is slidably connected to the No. 1 slide groove 115 and the outer surface of the connecting block is fixedly connected to the slide plate 112; there are two protective plates 118, and a fixed plate 119 is fixedly connected to one side of the protective plate 118, and the fixed plate 119 is hinged to the No. 3 connecting rod 117; there are two sliders 120, one end of which is slidably connected to the No. 2 slide groove 116, and the other end is fixedly connected to the protective plate 118.

[0079] When the protective assembly of the present invention is not attacked by heavy rain, the protective plates 118 on both sides are retracted on the surface of the base 114 and are close to each other in a closed state. When the overflow plate 5 is subjected to the pressure of heavy rain, it rotates, so that the No. 2 connecting rod 111 pushes the fixed block 113 hinged thereto. When the fixed block 113 drives the slide plate 112 to move on the No. 1 slide groove 115 opened on the surface of the base 114, since the slide plate 112 is fixedly connected to the connecting block and the connecting block is hinged to one end of the No. 3 connecting rod 117, when the slide plate 112 moves on the No. 1 slide groove 115, the slide plate 112 drives the No. 3 connecting rod 117 to rotate outward. One end of 117 is hinged to the fixed plate 119 and the fixed plate 119 is fixedly connected to the protective plate 118, so when the No. 3 connecting rod 117 rotates, it pushes the protective plates 118 on both sides away from each other and thus opens, and the protective plates 118 are fixedly connected to the slider 120. When the protective plate 118 is opened, it drives the slider 120 to move in the No. 2 slide groove 116, ensuring the deployment path of the protective plate 118. Since the protection range of the protective plate 118 is limited, a plastic film 12 is connected to both sides of the base 114 on one side of the protective plate 118. When the protective plate 118 is opened, the plastic film also unfolds, thereby reducing the erosion of grass by rainwater to the greatest extent.

[0080] When heavy rain pours down, in order to promote smooth drainage, drainage holes 13 are evenly distributed on both sides of the intercepting ditch 2. Part of the rainwater flows into the drainage holes 7 and is discharged to the drainage pipe 8, and part of the rainwater flows through the drainage holes 13 layer by layer into the drainage ditch 4 at the bottom of the slope.

[0081] When rainwater is discharged into the drainage hole 7, sand and soil on the surface of the slope will be brought in. In order to prevent the sand and soil from clogging the drainage hole 7, a filter screen is arranged at the mouth of the drainage hole 7 to ensure smooth drainage.

[0082] In the construction of water conservancy and hydropower projects, groundwater is also one of the important factors affecting the stability of the slope. Vegetation can not only protect the slope but also not affect the discharge of groundwater, thus protecting the entire ecological environment. However, vegetation must have suitable soil and fertilizer for planting. The present invention is provided with a vegetation breeding fence 14, in which vegetation grows. Fertilizer and soil can be laid in the breeding fence 14 for grass growth. At the same time, small through holes are provided at the bottom of the breeding fence 14 to promote the breathing of grass and the discharge of surface water.

[0083] In order to ensure the safety of the present invention in practice, the material of the spring 6 is set to be ultra-high strength steel, which has high strength and good toughness, and can ensure normal use in heavy rain.
