Description
Technical Field
[0001] The utility model relates to the technical field of steep cliff water collection and drainage, in particular to a soil steep cliff water collection and drainage structure. Background Technique
[0002] Soil steep cliffs are widespread in some mountainous areas in North China and Northwest China. Due to the long-term rain erosion of the mountain body, steep cliffs are formed, and the soil body is in danger of collapsing and falling at any time, seriously threatening the safety of farmland water conservancy and people's lives and property in surrounding villages. At present, mountain ecological restoration technologies are mostly used in industries such as mine restoration and road traffic slope protection. With the booming development of the agricultural economy, the number of agricultural economic construction projects has increased accordingly, and the governance methods that can comprehensively consider agricultural economic construction and ecological environment restoration are not yet perfect.
[0003] For typical valley-like construction sites, the slopes of the mountains on both sides are relatively large, and the steepest part of the slope can be close to 90°. It is a typical loess cliff landform. Coupled with the usual rain erosion, some local soil bodies are in jeopardy. In order to improve the slope stability and ensure the site safety, a soil steep cliff water collection and drainage structure is needed to improve the project quality, save construction costs, ensure the stability of the mountain body and the safety of villages, farmland, and landscape facilities in the valley, and improve the productivity of the agricultural ecosystem. Summary of the Invention
[0004] The purpose of the utility model is to solve the problems raised in the background technique, and provide a soil steep cliff water collection and drainage structure.
[0005] The technical solution of the utility model to achieve the above purpose is as follows:
[0006] A soil steep cliff water collection and drainage structure, including a soil steep cliff body, a water collection tank, a flow channel, a filter layer, a drainage baffle, a water inlet, a drainage pipe, a drainage ditch, and a flexible water pipe. A water collection tank is opened on the soil steep cliff body. There are multiple water collection tanks, which are distributed on the soil steep cliff body from top to bottom in sequence. Multiple flow channels are opened on the soil steep cliff body. The upper and lower ends of each flow channel are connected to a water collection tank respectively. One end of the lowermost flow channel is connected to a water collection tank, and the other end of the lowermost flow channel is connected to a drainage ditch. The height of the upper end of each flow channel is higher than the height of the filter layer in the water collection tank to which it is connected. The filter layer is located in the water collection tank and is fixedly connected to the water collection tank. The drainage baffle is located in the water collection tank and is fixedly connected to the water collection tank. The drainage baffle is located below the filter layer. An inlet is opened on the drainage baffle. One end of the drainage pipe is fixedly connected to the water collection tank, and the other end of the drainage pipe is fixedly connected to the drainage ditch. A flexible water pipe is installed at the place where each drainage pipe is connected to each other.
[0007] Preferably, green plants are provided on the soil steep cliff body, and the green plants are planted on the soil steep cliff body.
[0008] Preferably, the filter layer is divided into three layers, which are a gravel layer, a gravel soil layer, and a fine pebble layer from top to bottom in sequence, and the particle size of the filter layer gradually increases from top to bottom.
[0009] Preferably, a fixing bracket is provided on the drainage pipe. One end of the fixing bracket is fixedly connected to the drainage pipe, and the other end of the fixing bracket is fixedly connected to the soil cliff body.
[0010] Preferably, a baffle is provided on the drainage ditch, and the baffle is fixedly connected to the drainage ditch.
[0011] The utility model provides a soil cliff water collection and drainage structure, which has the following beneficial effects:
[0012] Through its structural design, during the construction of the device of the utility model, taking the contour line as the benchmark, balanced slope cutting and filling are carried out to reduce the slope rate of the soil cliff body, ensure the stability of the soil cliff body. After the slope cutting and filling of the soil cliff body, a water collection trough and a flow channel are built on the top and slope surface of the soil cliff body. A drainage baffle and a filter layer are sequentially laid from bottom to top in the water collection trough. After the water collection trough and the flow channel are built, each water collection trough is connected to the drainage ditch at the bottom of the slope through a drainage pipe. The places where the drainage pipes are connected to each other are connected by flexible water pipes. By using the drainage facilities combining the rigid drainage pipes and the flexible water pipes arranged, the drainage is ensured to be unobstructed, thereby reducing the scouring of rainwater on the slope body.
[0013] During normal drainage, the accumulated water collected at the top of the soil cliff body will be collected into the water collection trough. After being filtered by the filter layer in the water collection trough, impurities such as sediment in the accumulated water are filtered out. The filtered accumulated water enters the bottom of the water collection trough through the water inlet on the drainage baffle and flows into the drainage ditch through the drainage pipe. The filtered accumulated water can be used as agricultural water. When the rain is too heavy and other situations cause too much accumulated water, the accumulated water that cannot be processed by the filter layer in the upper water collection trough will flow into the lower water collection trough along the flow channel and be filtered by the filter layer in the lower water collection trough, preventing the situation that the drainage system cannot handle the excessive rainwater and causing scouring of the soil cliff body. Compared with the prior art, the utility model prevents the scouring of the soil cliff body by accumulated water through the way of gradually draining the soil cliff body, and at the same time, the accumulated water can be filtered. The filtered accumulated water can be used as agricultural water, increasing the agricultural industrial structure and promoting the development of agricultural economy.

It is characterized in that a water collection trough 2 is opened on the soil cliff body 1. There are multiple water collection troughs 2, which are distributed on the soil cliff body 1 from top to bottom in sequence. Multiple flow channels 3 are opened on the soil cliff body 1. The upper and lower ends of each flow channel 3 are respectively connected to a water collection trough 2. One end of the lowermost flow channel 3 is connected to a water collection trough 2, and the other end of the lowermost flow channel 3 is connected to the drainage ditch 8.

The drainage baffle 5 is located in the water collection trough 2 and is fixedly connected to the water collection trough 2. The drainage baffle 5 is located below the filter layer 4. A water inlet 6 is opened on the drainage baffle 5. One end of the drainage pipe 7 is fixedly connected to the water collection trough 2, and the other end of the drainage pipe 7 is fixedly connected to the drainage ditch 8. A flexible water pipe 9 is installed at the connection point of each drainage pipe 7.
[0021] In the present utility model, green plants 10 are provided on the soil cliff body 1, and the green plants 10 are planted on the soil cliff body 1; the roots of the green plants 10 planted on the soil cliff body 1 solidify the slope surface to prevent soil erosion and the formation of debris flows.
[0022] In the present utility model, the filter layer 4 is divided into three layers, and from top to bottom, they are a gravel layer, a crushed stone soil layer, and a fine pebble layer. The particle size of the filter layer 4 gradually increases from top to bottom, and the particles of any layer are not allowed to pass through the pores of the adjacent coarser layer. In this way, it can better play the role of filtering soil and draining water.
[0023] In the present utility model, a fixing frame 11 is provided on the drainage pipe 7. One end of the fixing frame 11 is fixedly connected to the drainage pipe 7, and the other end of the fixing frame 11 is fixedly connected to the soil cliff body 1; the rigid drainage pipe 7 is supported by the fixing frame 11 on the drainage pipe 7 to strengthen the strength of the drainage pipe 7 and make the drainage pipe 7 more stable.
[0024] In the present utility model, a shielding baffle 12 is provided on the drainage ditch 8, and the shielding baffle 12 is fixedly connected to the drainage ditch 8; the shielding baffle 12 on the drainage ditch 8 can prevent foreign objects from entering the drainage ditch 8.
[0025] In this implementation: During construction, with the contour line as the reference, balanced slope cutting and filling are carried out to reduce the slope rate of the soil cliff body 1 and ensure the stability of the soil cliff body 1. After slope cutting and filling of the soil cliff body 1, a water collection trough 2 and a flow channel 3 are built on the top and slope surface of the soil cliff body 1. A drainage baffle 5 and a filter layer 4 are successively laid in the water collection trough 2 from bottom to top. The filter layer 4 is divided into three layers, which are a gravel layer, a gravel soil layer, and a fine pebble layer from top to bottom, with the particle size gradually increasing. The particles of any layer are not allowed to pass through the pores of the adjacent coarser layer. In this way, it can better play the role of filtering soil and draining water. After the water collection trough 2 and the flow channel 3 are built, each water collection trough 2 is connected to the drainage ditch 8 at the bottom of the slope through a drainage pipe 7. The connection points of the drainage pipes 7 are connected by a flexible water pipe 9. By using the drainage facilities combining the rigid drainage pipes 7 and the flexible flexible water pipes 9 arranged, the drainage is ensured to be unobstructed, thereby reducing the scouring of the slope by rainwater. The rigid drainage pipe 7 is supported by a fixing frame 11 on the drainage pipe 7 to strengthen the strength of the drainage pipe 7 and make the drainage pipe 7 more stable.
[0026] During normal drainage, the accumulated water collected at the top of the soil cliff body 1 will be collected into the water collection trough 2. After being filtered by the filter layer 4 in the water collection trough 2, the sediment and other impurities in the accumulated water are filtered out. The filtered accumulated water enters the bottom of the water collection trough 2 through the water inlet 6 on the drainage baffle 5 and flows into the drainage ditch 8 through the drainage pipe 7. The baffle 12 on the drainage ditch 8 can prevent foreign objects from entering the drainage ditch 8. The filtered accumulated water can be used as agricultural water. When it rains too much and the accumulated water is excessive, the accumulated water that cannot be processed by the filter layer 4 in the upper water collection trough 2 will flow along the flow channel 3 into the water collection trough 2 of the next layer and be filtered by the filter layer 4 in the water collection trough 2 of the next layer, preventing the situation that the rainwater is too large and the drainage system cannot handle it, resulting in scouring of the soil cliff body 1. The roots of the green plants 10 planted on the soil cliff body 1 solidify the slope surface to prevent soil erosion and the formation of mudslides.
