Description

Technical Field

[0001] The present invention belongs to the technical field of ecological restoration devices, and in particular relates to an ecological restoration device for preventing and controlling soil erosion. Background Art

[0002] When carrying out slope greening ecological restoration in arid and semi-arid areas, the slopes are often threatened by severe soil erosion due to the special climate influence of drought, low rainfall, concentrated and intense precipitation. Soil erosion leads to land degradation and soil nutrient loss, resulting in low seed germination rate and difficulty in vegetation growth. In addition, the siltation and non-point source pollution caused by soil erosion, as well as the presence of heavy metals and other harmful substances in the land to be restored, further seriously affect the effectiveness of ecological restoration. To address the above problems, two solutions are currently commonly used: one is to use engineering measures such as artificial excavation of horizontal steps and construction of terraces for restoration, and the other is to directly transplant seedlings and sow vegetation for greening.

[0003] Engineering measures such as manually excavating horizontal steps and building terraces are widely used to prevent soil erosion. However, these measures are labor-intensive and costly. In practice, these measures often require additional vegetation cultivation to achieve ecological restoration.

[0004] Directly transplanting saplings and sowing vegetation simultaneously offers the benefits of slope protection and ecological restoration. However, this approach carries high maintenance costs and a long vegetation growth cycle. In arid and semi-arid climates, vegetation growth is poor, making it difficult to achieve both soil erosion prevention and ecological restoration in the early stages.

[0005] In ecologically fragile areas in arid and semi-arid regions, the above measures are unable to meet the needs of ecological restoration on bare soil slopes with severe soil erosion.

[0006] Therefore, it is necessary to design an ecological restoration device for preventing and controlling soil erosion to solve the above problems. Summary of the Invention

[0053] Furthermore, the auxiliary fixing part includes a fixing plate 13, which is fixedly connected to the outer wall of the connecting end of the fixing body 12 and the support body 11. A circular hole 131 is opened on the fixing plate 13, and a wooden needle 14 is slidably inserted into the circular hole 131. A small ring 141 is provided on the outer wall of one end of the wooden needle 14.

[0054] Furthermore, the sand-retaining and water-purifying module 2 includes an incoming water surface baffle 21 and a back water surface baffle 22. The size of the incoming water surface baffle 21 is larger than that of the back water surface baffle 22. Both the incoming water surface baffle 21 and the back water surface baffle 22 are provided with a number of large through holes 231. A third dust-proof net 233 is provided on the large through holes 231. A water purification cavity 23 is formed between the incoming water surface baffle 21 and the back water surface baffle 22. A material bag 232 is provided in the water purification cavity 23. A vegetation growth space 24 is formed outside the water purification cavity 23 and between the incoming water surface baffle 21 and the back water surface baffle 22.

[0055] The sediment interception and water purification module 2 has two functions: one is to intercept the slope runoff, purify the water quality, and when the runoff is too large, it can guide the excess water into the water-guiding planting module 1;

[0056] Secondly, when using rainfall and irrigation water, the sand interception and water purification module 2 can store the water overflowing from the water-guiding planting module 1 and use evaporation to increase the air humidity for long-term moisture retention.

[0057] Furthermore, the rainfall collection module 3 includes a rainwater collecting surface 31, the top of the rainwater collecting surface 31 is tilted, the top of the rainwater collecting surface 31 is higher than the center, a baffle ring edge 311 is provided around the top of the rainwater collecting surface 31, and a bayonet 32 ​​is provided at the bottom center of the rainwater collecting surface 31. The rainwater collecting surface 31 is detachably connected to the top of the water-guiding planting module 1 through the bayonet 32.

[0058] Furthermore, the irrigation cover top 4 includes a top cover 41, an irrigation pipe 42 is passed through the center of the top cover 41, a fourth dustproof net 421 is provided at the top of the irrigation pipe 42, the bottom end of the irrigation pipe 42 is provided in the water-conducting planting module 1, and an air pressure balance hole 43 is provided at the top of the irrigation pipe 42, and the air pressure balance hole 43 is located below the top cover 41.

[0059] When rainfall occurs, rainwater passes through the rainwater collection surface 31 that descends toward the center around the rainfall collection module 3 and reaches the pore zone 112 for rainwater entry provided above the water-guiding planting module 1, thereby preventing raindrops from directly hitting the ground and causing splash erosion, and enters the water storage cavity 111 of the water-guiding planting module 1. Under the influence of gravity, through the water absorption and water-guiding effects of the moisturizing sponge 115, natural rainwater can utilize the water storage cavity 111, the moisturizing sponge 115, the high water pipe 121, and the low water pipe 122 for water storage and introduction into the ground, thereby reducing the efficiency of rainwater conversion into surface runoff and reducing soil erosion. In addition, when the rainfall intensity is large and reaches the maximum soil infiltration rate, the rainwater in the water storage cavity 111 can enter the water purification cavity 23 of the sand-trapping and water purification module 2 through the medium-sized through-hole 113 in the upper middle portion of the water-guiding planting module 1, and further utilize the adsorption effect of the adsorbent polymer material package 232 in the water purification cavity 23 to store water. When the maximum storage capacity of the device is reached, the excess runoff will seep out through the large through-holes 231 of the sediment interception and water purification module 2. The device converts the highly erosive rainfall that directly hits the surface into low-erosive runoff with a small flow rate and slow velocity, reducing soil and water loss.

[0060] When soil erosion occurs, through the blocking effect of the incoming water surface baffle 21 of the sand-blocking and water-purifying module 2, the device can slow down the flow rate and sand-carrying force of the water from above, causing the sediment in the runoff to settle and accumulate, thereby inhibiting the loss of soil particles on the slope; through the blocking effect of the third dust-proof net 233, the sediment in the runoff is retained outside the incoming water surface baffle 21, and the runoff enters the water purification cavity 23 of the sand-blocking and water-purifying module 2; through the adsorption effect of the adsorbent polymer material package 232 in the water purification cavity 23, water is accumulated and pollutants such as heavy metals in the runoff are purified, thereby achieving the purpose of reducing runoff and purifying water quality. In addition, during the runoff period after rainfall, the device blocks more runoff sediment, causing the water level of the incoming water to rise. When the storage capacity in the clean water cavity 23 reaches the maximum, the runoff purified by the adsorptive polymer material package 232 can enter the water storage cavity 111 of the water-guiding planting module 1 through the medium-sized through hole 113 in the upper middle part of the water-guiding planting module 1, and further utilize the water storage cavity 111, the thin layer of moisturizing sponge 115, the high water pipe 121, and the low water pipe 122 to store water and guide it into the ground, thereby reducing runoff and reducing soil erosion.

[0061] When rainfall or purified runoff enters the water storage cavity 111 of the water-conducting planting module 1, it mixes thoroughly with the water-soluble slow-release fertilizer package 114 therein. Nutrient-containing water penetrates into soil layers at varying depths through the upper and lower water conduits 121, 122, promoting seed germination and root growth in the seed packages 15. During droughts, irrigation water can be injected directly into the water storage cavity 111 using the water pipe connected to the irrigation cover 4, achieving the same effect. Artificial irrigation requires the irrigated soil to reach saturated water content, with the irrigation water filling the water storage cavity 111 and fully moistening the adsorbent polymer package 232 in the water purification cavity 23. During the dry period following rain, this device can prevent direct sunlight from reaching young plants, thereby improving their survival rate. Furthermore, through the evaporation of water from the adsorbent polymer package 232 in the water purification cavity 23 and the shading and condensation effect of the rainwater collection surface, the surrounding air and the interior of the water-conducting planting module 1 are moisturized and cooled, promoting plant growth and reducing soil moisture evaporation. Furthermore, the sediment intercepted by the incoming water baffle 21 is often highly fertile. The wooden needles 14, while securing the device, also serve to guide water and increase soil porosity, facilitating the rooting and growth of vegetation. Due to the vegetation's phototropism and hydrotropism, the growing vegetation can escape from the semi-enclosed vegetation growth space 24 protecting the seedlings, achieving a comprehensive and comprehensive vegetation restoration effect.

[0062] When the water volume in the water storage cavity 111 of the water-conducting planting module 1 is low, the water flows directly into the ground through the water pipes on both sides of the fixed body 12. As the water volume in the water storage cavity 111 increases and the water level rises, the water flows sequentially into the lower water pipe 122 and then the higher water pipe 121 in the middle, thus increasing water diversion efficiency. Furthermore, a medium-sized through-hole 113 in the upper portion of the water-conducting planting module 1 connects the water storage cavity 111 with the water purification cavity 23. When the water volume in each water channel reaches its maximum, the water storage space is increased.

[0063] On general slopes, the system is laid out in a staggered pattern along the contour lines. Where gullies are well developed, the system is laid directly at the gully head. Where larger gullies are well developed, the system is laid out in a combined oblique pattern.
