Description

Technical Field

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

[0002] When conducting slope revegetation ecological restoration in arid and semi-arid regions, under the influence of special climates with little rainfall, concentrated and intense precipitation, slopes are often threatened by severe soil erosion. Soil erosion has led to land degradation and soil nutrient loss, resulting in low seed germination rates and difficult vegetation growth. In addition, sediment deposition and non-point source pollution generated along with soil erosion, as well as harmful substances such as heavy metals existing in the land to be restored, have further seriously affected the ecological restoration effect. To address the above problems, two solutions are commonly adopted at present: one is to use engineering measures such as manually excavating horizontal steps and building terraced fields for restoration, and the other is to directly transplant saplings and sow vegetation for revegetation.

[0003] Engineering measures such as manually excavating horizontal steps and building terraced fields are widely used in soil erosion prevention and control. However, such engineering measures require a large amount of labor and high costs. In actual projects, after manually excavating horizontal steps and building terraced fields, additional vegetation needs to be cultivated to achieve the effect of ecological restoration.

[0004] The method of directly transplanting saplings and sowing vegetation has the effects of slope protection and ecological restoration at the same time. However, the direct transplanting of saplings and sowing of vegetation have high artificial maintenance costs and long vegetation growth cycles. Under the influence of arid and semi-arid climates, the vegetation grows poorly. It is difficult to achieve the effects of soil erosion prevention and control and ecological restoration in the early stage.

[0005] In the ecologically fragile areas of arid and semi-arid regions, the above measures cannot meet the needs of ecological restoration on bare soil slopes with severe soil erosion.

[0052] Further, a second dust-proof net 124 is arranged at the bottom of the outer side wall of the fixing body 12.

[0053] Further, the auxiliary fixing part includes a fixing plate 13. The fixing plate 13 is fixedly connected to the outer side wall of the connection end of the fixing body 12 and the supporting body 11. A round hole 131 is provided on the fixing plate 13. A wooden needle 14 is slidably inserted through the round hole 131. A small ring 141 is arranged on the outer side wall of one end of the wooden needle 14.

[0054] Further, the sediment interception and water purification module 2 includes a water-facing baffle 21 and a backwater-facing baffle 22. The size of the water-facing baffle 21 is larger than that of the backwater-facing baffle 22. A number of large through holes 231 are provided on both the water-facing baffle 21 and the backwater-facing baffle 22. A third dust-proof net 233 is arranged on the large through holes 231. A water purification cavity 23 is formed between the water-facing baffle 21 and the backwater-facing baffle 22. A material package 232 is arranged in the water purification cavity 23. A vegetation growth space 24 is formed between the water-facing baffle 21 and the backwater-facing baffle 22 outside the water purification cavity 23.

[0055] The sediment interception and water purification module 2 has two functions. One is to intercept the slope runoff, purify the water quality, and be able to introduce the excess water into the water-conducting planting module 1 when the runoff is too large;

[0056] Second, 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 inclined, the top of the rainwater collecting surface 31 is higher than the center, a baffle ring edge 311 is arranged around the top of the rainwater collecting surface 31, and a bayonet 32 is arranged at the bottom center of the rainwater collecting surface 31. The rainwater collecting surface 31 is detachably connected to the top of the water-conducting 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 arranged at the top of the irrigation pipe 42, the bottom end of the irrigation pipe 42 is arranged in the water-conducting planting module 1, and an air pressure balance hole 43 is arranged 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 is lowered toward the middle around the rainfall collection module 3 to reach the pore zone 112 for rainwater to enter the top of the water-conducting planting module 1, thereby preventing raindrops from directly hitting the ground and causing splashing erosion, and entering the water storage cavity 111 of the water-conducting planting module 1. Under the influence of gravity, through the water absorption and water-conducting effect of the moisturizing sponge 115, natural rainwater can be stored and directed into the ground using the water storage cavity 111, the moisturizing sponge 115, the high water pipe 121, and the low water pipe 122, 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 water purification module 2 through the medium-sized through hole 113 in the upper middle part of the water-conducting 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 directly hitting the surface into low-erosive runoff with a small flow rate and slow flow rate, thereby reducing soil erosion.

[0060] When soil and water loss occurs, through the blocking effect of the incoming water surface baffle 21 of the sediment and water purification module 2, the device can slow down the flow velocity and sediment-carrying capacity of the incoming water above, causing the sediment in the runoff to settle and accumulate, and inhibiting the loss of soil particles on the slope surface; through the blocking effect of the third dust-proof net 233, the sediment in the runoff is left outside the incoming water surface baffle 21, and the runoff enters the water purification cavity 23 of the sediment and water purification module 2; through the adsorption effect of the adsorbent polymer material package 232 in the water purification cavity 23, water is stored and heavy metal and other pollutants in the runoff are purified, so as to achieve the purpose of reducing runoff and purifying water quality. In addition, during the water collection period after rainfall, the blocking of runoff sediment by the device intensifies, resulting in an increase in the water potential of the incoming water. When the storage volume in the water purification cavity 23 reaches the maximum, the runoff purified by the adsorbent polymer material package 232 can enter the water storage cavity 111 of the water guiding and planting module 1 through the medium-sized through hole 113 in the upper part of the water guiding and planting module 1, and further use the water storage cavity 111, the thin-layer moisture-retaining sponge 115, the high water-conducting pipe 121 and the low water-conducting pipe 122 to store water and introduce it into the ground, thereby reducing runoff and soil and water loss.

[0061] When rainfall or purified runoff enters the water storage cavity 111 of the water guiding and planting module 1, it can be fully mixed with the water-soluble slow-release fertilizer package 114 therein. The water containing nutrients seeps into the soil layers at different depths through the high water-conducting pipe 121 and the low water-conducting pipe 122, promoting the germination of seeds and the growth of roots in the seed package 15. During the dry period, by using the water connection pipe on the irrigation cover 4, the irrigation water can be directly injected into the water storage cavity 111 to achieve the same effect. Artificial irrigation requires the irrigation soil to reach the saturated water content, and the irrigation water fills the water storage cavity 111 and fully wets the adsorbent polymer material package 232 in the water purification cavity 23. During the dry period after rain, the device can avoid direct sunlight on the vegetation seedlings to improve the survival rate of the vegetation. In addition, through the water evaporation effect of the adsorbent polymer material package 232 in the water purification cavity 23 and the shading and condensation effect of the rainwater collection surface, the humidity and temperature of the surrounding air and the inside of the water guiding and planting module 1 are maintained, promoting vegetation growth and reducing soil water evaporation. In addition, the sediment blocked by the incoming water surface baffle 21 often has high fertility. The wooden needles 14 have a certain water guiding and soil pore increasing effect while fixing the device, facilitating the rooting and development of vegetation. According to the phototropism and hydrotropism of vegetation, the continuously growing vegetation can break away from the semi-enclosed vegetation growth space 24 for protecting seedlings, achieving the effect of vegetation revegetation from point to area.

[0062] When the water volume in the water storage cavity 111 of the water-conducting planting module 1 is small, the water flow will directly enter the ground through the water-conducting pipes on both sides of the fixed body 12. When the water volume in the water storage cavity 111 increases and the water level rises, the water flow will successively enter the low water-conducting pipe 122 and the high water-conducting pipe 121 in the middle and then enter the ground, so as to increase the water-conducting efficiency. In addition, the medium-sized through holes 113 arranged in the upper and middle parts of the water-conducting planting module 1 connect the water storage cavity 111 with the purified water cavity 23. When the water volumes of different water passages reach the maximum, the water storage space can be increased.

[0063] Generally, on gentle slopes, they are arranged staggeredly along the contour lines. At the places where rills develop on the slope surface, cut-off ditches are directly arranged. At the places where larger gullies develop, they are arranged in a combined and obliquely inserted manner.
