[0026] Since the vegetation coverage rate of the spoil ground is very low, when it rains, the soil is impacted by the rainwater and is easily carried away by the rainwater, resulting in soil loss. Moreover, the soil carried away by the rainwater will be deposited in places where the water flow velocity is gentle, causing damage to the surrounding ecological environment.
[0027] Therefore, this application provides a soil erosion prevention structure for the spoil ground, aiming to solve the technical problem of serious soil loss in the spoil ground.
[0028] Please refer to Figure 1 , the soil erosion prevention structure of the spoil ground mainly includes a retaining wall 1, a gravel layer 2, a stone layer 3, and a water collecting trough 4; the retaining wall 1 is built at the bottom of the slope of the spoil ground, giving the spoil ground a clear boundary and effectively avoiding the problem of the collapse and spread of the spoil ground.
[0029] On one side of the retaining wall 1 close to the waste dump, a gravel layer 2, a stone layer 3, and green plants 11 are successively laid along the slope of the waste dump. The green plants 11 are composed of vegetation with well-developed roots. The particle size of the stones in the gravel layer 2 is smaller than that of the stones in the stone layer 3. When it rains, the rainwater carries the soil on the waste dump and flows downward along the slope of the waste dump. First, the green plants 11 slow down and block it in the first step, and then successively pass through the stone layer 3 and the gravel layer 2 for the second block and filtration, so as to block the soil in the muddy water as much as possible, thereby achieving the purpose of reducing the soil loss of the waste dump. At the same time, during the growth process of the green plants 11, their roots will spread to the stone layer 3, thus forming a net-like root system between the stone layer 3, greatly improving the effect of the stone layer 3 in filtering muddy water and enhancing the ability of the stone layer 3 to prevent soil loss. Moreover, over time, the soil layer around the green plants 11 increases, achieving the effect of raising the soil for the vegetation and being beneficial to the growth of the vegetation.
[0030] In this embodiment, the height of the retaining wall 1 is greater than the lowest point of the gravel layer 2 and less than the highest point of the gravel layer 2. When the rain is relatively small, due to the water impermeability of the retaining wall 1, the water flow is likely to deposit on the side of the retaining wall 1 close to the waste dump, so as to increase the water content at the edge of the waste dump. During the growth process of the vegetation in the green plants 11, it will spread towards the side where the retaining wall 1 is located, thereby reducing the force on the retaining wall 1 and effectively reducing the risk of the retaining wall 1 collapsing. When the rain is relatively large, the rainwater can conveniently flow over the retaining wall 1 and continue to flow downward, reducing the force on the retaining wall 1 and extending the service life of the retaining wall 1.
[0031] On the side of the retaining wall 1 away from the waste dump, a water accumulation tank 4 is provided. A net plate 5 is covered on the water accumulation tank 4, and a sandy soil layer 12 is laid on the net plate 5, and turf 6 is provided on the sandy soil layer 12. When the rain is relatively large, after being filtered, the relatively clear rainwater flows over the retaining wall 1 and then flows onto the turf 6. Subsequently, after being filtered by the turf 6, the sandy soil layer 12, and the net plate 5, it enters the water accumulation tank 4 for storage for subsequent use during drought or is diverted out by the water accumulation tank 4. When the rainwater passes through the turf 6 layer, the soil in the muddy water is filtered out, thereby achieving the purpose of reducing soil loss. The deposited soil also becomes loose and permeable under the action of the roots of the turf 6, enabling the water to flow into the water accumulation tank 4. Moreover, due to the deposition of the soil, the turf 6 is also easier to grow and survive.
[0032] In this embodiment, it can be imagined that the highest water level of the water accumulation tank 4 is flush with the installation height of the net plate 5 to prevent the water level in the water accumulation tank 4 from being too high and causing the turf 6 to die due to waterlogging.
[0033] In this embodiment, the particle size of the stones in the gravel layer 2 is 20 millimeters to 40 millimeters.
[0034] In this embodiment, the particle size of the stones in the stone layer 3 is greater than 5 centimeters.
[0035] In some specific embodiments, a barrier net 7 is embedded in the gravel layer 2. The barrier net 7 forms a framework structure in the gravel layer 2, which can effectively increase the stability of the gravel layer 2 and effectively avoid the problem that the gravel layer 2 is washed away or flushed during heavy rain.
[0036] In some specific embodiments, a water retaining wall 8 is provided on the other side of the turf 6 relative to the retaining wall 1, so as to form a groove between the retaining wall 1 and the water retaining wall 8. In the weather with heavy rain, the rainwater cannot be discharged into the water accumulation tank 4 in time. The rainwater is diverted through the groove and discharged in time, making the drainage planned.
[0037] In some specific embodiments, a water pump 9 is provided in the water accumulation tank 4, and a nozzle 10 for spraying water onto the turf 6 is provided on the water retaining wall 8. The water outlet end of the water pump 9 is connected to the nozzle 10 through a pipeline. In the dry season, the water in the water accumulation tank 4 can be sprayed onto the turf 6 through the water pump 9 and the nozzle 10, so as to ensure the normal survival of the turf 6.
[0038] In some specific embodiments, the nozzles 10 are arranged at intervals along the water retaining wall 8, effectively ensuring that all the turf 6 can be sprayed.
[0039] The embodiments of the present application have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application or the improvement of the technology in the market, or to enable other ordinary technicians in the technical field to understand the disclosed embodiments.
