Description

Technical Field

[0001] The utility model belongs to the field of soil and water conservation ecological restoration of barren mountain slopes in western cold and arid areas, in particular to an ecological restoration structure, and relates to a soil and water conservation ecological restoration structure for barren mountain slopes in western cold and arid areas. Background Art

[0002] The slope of the barren mountain terrain is between 20° and 45°. When the rainfall lasts for 10 to 20 minutes and the rainfall intensity is greater than 40 mm / h, runoff will be generated on the slope, resulting in floods, which will cause serious soil and water erosion on the slope. In the past decade, due to climate warming, air pollution and other reasons, the amount of meltwater from ice and snow has increased, the terrain slope is large, and the amount of water formed by seasonal meltwater from ice and snow and rainfall is large, which washes away the surface soil and reduces the soil infiltration capacity, causing serious soil and water erosion. The soil structure of the slope is destroyed by floods, and the organic matter and fine particles in the soil are washed away by floods. The water conservation capacity is reduced, resulting in serious vegetation decline and a situation that cannot be naturally restored.

[0003] The possibility of natural recovery of barren mountain slopes caused by floods, soil erosion (or mudslides) and vegetation decline due to precipitation and snowmelt is extremely small. The reasons are: (1) In spring and summer, due to rainfall or rising temperatures, snowmelt increases, resulting in frequent micro-erosion on barren mountain slopes. A large amount of mineral nutrients and organic matter in the soil are carried downstream with slope erosion, and the fertility of the mountain slope soil continues to decline. At the same time, flood alluvial deposits also damage downstream farmland irrigation and water supply channels; (2) In cold and arid areas, barren mountains have less precipitation, longer winters, and lower vegetation coverage. The slope ecology is fragile. Precipitation damages the soil layer structure of the vegetation on the barren mountain slopes, and the water retention of the slope soil becomes increasingly poor, further deteriorating the vegetation growth environment.

[0004] The snowmelt season in Xinjiang mainly occurs after April. Due to the sharp rise in temperature, the melting snow and ice will cause small floods. This short-duration and high-intensity meltwater runoff damages the soil structure and landform of the barren mountain slopes, resulting in a decrease in the soil moisture conservation capacity of the barren mountain slopes and lower vegetation coverage. From July to August each year, the slope water is composed of rainfall and meltwater from ice and snow. The runoff is relatively large and the convergence speed is fast, which washes away the topsoil of the slope, easily creates pits and gullies on the ground, and causes serious soil erosion. It also causes damage to downstream farmland, roads, channels, bridges and other buildings.

[0005] In summary, the utility model provides a soil and water conservation ecological restoration structure for barren mountain slopes in cold and arid areas in the western region to solve the above-mentioned problems. Summary of the invention

[0038] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0039] Reference Figure 1-7 , is a water and soil conservation ecological restoration structure for barren mountain slopes in cold and arid areas in the western region disclosed by the utility model, comprising a pond 1, a water diversion ditch 2, a small cylinder 3, a water collecting bucket 4 and a straw grid 5, the pond 1 is installed on one side of the water collecting bucket 4, the small cylinder 3 is installed on one side of the water diversion ditch 2, the small cylinder 3 is fixedly connected to the water collecting bucket 4, a drip irrigation pipe 6 is fixedly installed on one side of the water collecting bucket 4, the drip irrigation pipe 6 is cross-laid with the water diversion ditch 2, and the straw grid 5 is laid on the water diversion ditch 2.

[0040] Rainwater and melted snow and ice fall into the pond 1 and are collected. When the saplings 10 are urgently needed to be irrigated, the water in the pond 1 enters the water collecting bucket 4 for irrigation by receiving information. The water diversion ditch 2 can disperse the water volume of the slope convergence and reduce the water flow speed, and drain the convergence water volume generated in the low-lying area. By reducing the distance between the upper and lower water diversion ditches 2, reducing the convergence area, and shortening the convergence time, the peak value of the incoming water can be controlled and resolved. The water flow in the water diversion ditch 2 enters the small cylinder 3, and the small cylinder 3 can filter the water flow. The filtered water flow enters the water collecting bucket 4 and is collected. The water collecting bucket 4 can transport water to the drip irrigation pipe 6, which is convenient for the drip irrigation pipe 6 to irrigate the saplings 10.

[0041] The width of the straw grid 5 is 2 m. Straw bundles are laid at the bottom of the water diversion ditch 2. The upper part of the water diversion ditch 2 is planted with saplings 10. The part of 0.8 m is covered with loose soil inside and below the water diversion ditch 2. The length of the straw grid 5 is determined by the length of the water diversion ditch 2. The square straw grid 5 has a contractible function in the length direction. Therefore, the length of the straw grid 5 is determined according to the terrain conditions. The square straw grid 5 woven from straw stalks has the characteristics of telescopic ability and equilateral shape. The sides of the straw grid 5 are aligned with the terrain slope. The angle formed by the straw grid 5 is 30°, so the sides of the straw grid 5 hinder the flow rate of water and reduce the flow rate and confluence time of water. The straw grid 5 covers the water diversion ditch 2. The straw grid 5 itself has the ability to absorb water, absorbs part of the rainwater, and maintains the humidity of the lower part. The straw grid 5 below the water diversion ditch 2 slows down the confluence time of rainwater, protects the side ridge of the water diversion ditch and loose soil, and reduces the evaporation of the soil under the straw grid 5, so as to maintain the soil moisture for a long time. The form of the straw grid 5 is determined to be square through experiments.

[0042] The drip irrigation pipe 6 is connected to the drip irrigation pipe 6 after the electromagnetic valve 2 405 installed at the rear of the water collection bucket 4. The drip irrigation water diversion ditch is irrigated in the opposite direction. The intersection of the drip irrigation pipe 6AB and BC is directly connected. Figure 6As shown, sewage and water are discharged through a straight-through method, and the head end of the drip irrigation pipe 6 is designed to maintain a drop of 0.5m. Self-pressure drip irrigation is formed when water is supplied through the drop. The design of the water diversion ditch 2, the water collection bucket 4 and the drip irrigation pipe 6 is based on the slope conditions. The mountain is composed of a ridge 8, a saddle 12 and a valley 11. The water diversion ditch 2 is designed in a bidirectional direction of the ridge 8 from the valley 11 (the gradient of the water diversion ditch 2 is determined according to the actual terrain conditions); a water collection bucket 4 is set at the end of each water diversion ditch 2; the drip irrigation pipe 6 is connected to the water diversion ditch 2 from the end of the water diversion ditch 2. The ditch 2 supplies water in the reverse direction (a hole is drilled between the drip irrigation pipe 6 and the root point of the planted sapling 10 to install a dripper, and only the sapling 10 is irrigated. One sapling 10 is planted at each junction of the water diversion soil ditch 2 and the drip irrigation pipe 6). The two drip irrigation pipes 6 are connected with a straight connection at the junction of the valley 11, and sewage and drainage can be discharged when necessary. The control of the number of saplings 10 planted is that each water diversion soil ditch 2 can be connected to 1-5 drip irrigation pipes 6 after the solenoid valve 2405 at the end. When the planting density of the saplings 10 needs to be adjusted, the drip irrigation pipe 6 needs to be added, and the layout position is as follows Figure 7 As shown, the number and density of planted seedlings 10 can be increased.

[0043] Reference Figure 2 In this embodiment, a windbreak wall 101 and a dirt screen cover 102 are fixedly installed on the top of the pond 1, a sewage pipe 103 is fixedly installed on the side wall of the pond 1, a sewage valve 104 is fixedly installed in the sewage pipe 103, an emergency water supply pipe 105 is fixedly installed on the bottom of the side wall of the pond 1, and a solenoid valve 106 is fixedly installed in the emergency water supply pipe 105.

[0044] Since there is more precipitation in the mountainous areas in summer and thicker snow in winter, but the wind is strong on the sunny side of the mountainous areas and the wind blows away the snow, a pond 1 is built on the top of the mountain in the form of an elliptical basin. A windbreak wall 101 is set upstream to collect more rainwater and ice and snow. The sewage net cover 102 can filter the water flowing into the pond 1. Opening the sewage valve 104 can facilitate the sewage inside the pond 1 to be discharged through the sewage pipe 103. When the saplings 10 are urgently needed to be irrigated, the solenoid valve 106 receives the information and opens, and the water in the pond 1 enters the water collection bucket 4 through the emergency water supply pipe 105, which is convenient for watering the saplings 10.

[0045] Reference Figure 3 The water diversion ditch 2 of this embodiment is divided into an outer slope 201, an inner slope 202, a ditch bottom 203 and a mountain side 204.

[0046] The water diversion ditch 2 is mainly designed to disperse and converge the water in the low-lying areas of the mountainous area. According to the terrain conditions, the water diversion ditch 2 is excavated and constructed in the low-lying areas of the mountainous area. The water diversion ditch 2 is arranged along the contour line as much as possible, and the angle between the contour line and the water diversion ditch 2 is less than or equal to 10 degrees. The flow velocity of the slope (gradient) of the water diversion ditch 2 must satisfy that the flow velocity of the water diversion ditch 2 is greater than the non-silting flow velocity and less than the non-flushing flow velocity (V non-silting < V design < V non-flushing). The form of the water diversion ditch is close to a trapezoidal channel. The water flows in the ditch bottom 203 between the inner slope 202 and the mountain side 204, and the bulge formed by the outer slope 201 and the inner slope 202 can be used to block water.

[0047] Reference Figure 5 In this embodiment, a filter cover 301 is fixedly installed on the top of the small cylinder 3, sand particles 302 are installed in the small cylinder 3, a filter screen 303 is fixedly installed on the side wall of the small cylinder 3, a second sewage pipe 304 is fixedly installed on the bottom of the small cylinder 3, and a second sewage valve 305 is fixedly installed in the sewage pipe 304.

[0048] The filter cover 301 can filter the water flow entering the small cylinder 3, and the water flow in the water diversion ditch 2 enters the small cylinder 3. The sand particles 302 in the small cylinder 3 can filter the water flow for the first time. The filtered water flow settles at the bottom of the small cylinder 3, and the sedimentation is the second filtration. The settled water flow enters the filter screen 303, and the filter screen 303 can filter the water flow for the third time. The filter screen 303 can be connected with the water collecting bucket 4, and the filtered water flow enters the water collecting bucket 4 to be stored. Open the second sewage valve 305, and the sediment at the bottom of the small cylinder 3 flows out through the second sewage pipe 304. The small cylinder 3 is filled with sand particles 302 inside and has a filter screen 303 on the side. Its size is determined by the rainfall intensity and the terrain slope. A height of 20 cm is left between the sand particles 302 in the small cylinder 3 and the top of the small cylinder 3. A filter screen 303 is set on the side of the small cylinder 3 filled with sand particles 302, and the height of the filter screen 303 is below 20 cm from the top of the small cylinder 3.

[0049] Reference Figure 5 In this embodiment, an exhaust pipe 401 is fixedly installed on the top of the water collecting barrel 4, and an exhaust valve 402 is fixedly installed in the exhaust pipe 401. A drip irrigation water supply pipe 403 and a sewage pipe 404 are fixedly installed on the side wall of the water collecting barrel 4, and a solenoid valve 405 and a sewage valve 406 are fixedly installed in the drip irrigation water supply pipe 403 and the sewage pipe 404 respectively.

[0050] The water collection bucket 4 is also a cylinder, and its height and diameter are determined by the slope of the midstream mountain area and the distribution of precipitation. The water collection bucket 4 is used to store excess water during rainfall. When it does not rain for more than 10 days (or the soil moisture content drops to the wilting coefficient), the soil moisture content detector (transceiver and receiver) in the field notifies the network system, and the system automatically opens the electromagnetic valve 2 405 through the program, and the water in the water collection bucket 4 flows into the drip irrigation water supply pipe 403, and the drip irrigation water supply pipe 403 is connected to the drip irrigation pipe 6, and the water in the drip irrigation water supply pipe 403 flows into the drip irrigation water supply pipe 403. Enter the drip irrigation pipe 6 to facilitate drip irrigation of the saplings 10 by the drip irrigation pipe 6. When the water in the water collecting bucket 4 reaches the lowest designed water level, the solenoid valve 2 405 is automatically closed through the prompt of the alarm balloon 7 to stop the drip irrigation operation. When the rainfall intensity is large or the water collecting bucket 4 is full of water, the alarm balloon 7 reaches the top point of the water collecting bucket 4 under the action of buoyancy, and the alarm balloon 7 gives an alarm prompt again. The solenoid valve 2 405 is automatically opened to carry out drip irrigation operations. By opening the drain valve 3 406, the drain pipe 3 404 can conveniently discharge the sewage inside the water collecting bucket 4.

[0051] Reference Figure 4 and Figure 6 In this embodiment, an alarm balloon 7 is fixedly installed in the water collecting barrel 4, and the water collecting barrel 4 is installed on the ridge 8. A foundation pit 9 is excavated on one side of the water diversion ditch 2, and saplings 10 are planted in the foundation pit 9. There are valleys 11 between the ridges 8, and saddles 12 are formed between the ridges 8, and saplings 10 are planted in the valleys 11.

[0052] If the rainfall lasts for a long time and the water collecting bucket 4 is almost full of water, the alarm system automatically opens the electromagnetic valve 2 405 to prevent the water in the water collecting bucket 4 from overflowing. The system receives the moisture content information through the soil detector, prompts the irrigation time, and detects the dynamics of the water amount in the water collecting bucket 4. The water collecting bucket 4 is installed on the ridge 8 to facilitate the downward flow of water. The water in the water diversion ditch 2 flows into the foundation pit 9, which can water the saplings 10 inside the foundation pit 9, which is beneficial to ecological restoration.

[0053] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
