Technical Field

[0001] The invention relates to an ecological restoration device for a high and steep slope of a mine and a use method thereof, and belongs to the field of slope restoration. Background Art

[0002] When carrying out ecological restoration of slopes, the soil of the slopes must be reinforced first to prevent rainwater erosion before the vegetation has taken root, causing serious soil loss on the slopes and affecting vegetation growth. The commonly used method is to cover the slopes with concrete. Although this can prevent soil loss, the cost of using concrete is high, and the concrete covers most of the soil, affecting soil water absorption, resulting in the vegetation planted on the slopes not having enough water for its growth. Therefore, it is necessary to make improvements. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problems existing in the background technology and to provide an ecological restoration device for high and steep slopes in mines and a method for using the same.

[0006] A method for using a mine steep slope ecological restoration device, the method comprising the following steps:

[0007] Step 1: When it rains, rainwater from the upper surface of the steep slope flows into the pipe through the water diversion trough, and finally flows into the drainage trough along the pipe for discharge;

[0008] Step 2: When rainwater on the steep slope flows downward to the position of the fixed pipe, it will flow into the interior of the fixed pipe through the through hole, and then flow into the pipeline along the connecting pipes on both sides and be discharged.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention drains water through pipes, connecting pipes and fixed pipes, which can more effectively drain excess water, reduce the scouring of soil by water flow, and thus slow down soil loss; and the present invention only needs to open a small number of grooves on the steep slope, without the need to cover the slope over a large area, and does not affect soil water absorption, thereby achieving the purpose of not affecting vegetation growth.

[0013] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0014] Specific implementation method 1: Figure 1-3 As shown, this embodiment records an ecological restoration device for high and steep slopes in a mine, including a steep slope 1, a pipeline 2, a connecting pipe 3 and an interception device 4; a plurality of transverse and vertical grooves 13 are provided on the slope surface of the steep slope 1; the pipeline 2 is installed in the vertical groove 13, and a through hole 22 is provided on the pipeline 2; one end of the connecting pipe 3 is fixedly connected in the through hole 22, and the other end of the connecting pipe 3 is fixedly connected to the interception device 4.

[0015] The interception device 4 includes a fixed tube 41; the fixed tube 41 is fixedly connected to the connecting tube 3, and a spiral plate 43 is fixedly connected to the inner wall of the fixed tube 41; a plurality of through holes 42 arranged along the direction of the central axis of the fixed tube 41 are provided on the outer circumferential surface of the fixed tube 41.

[0016] The through hole 42 on the outer circumferential surface of the fixed pipe 41 is arranged toward the steep slope 1 at the upper end of the fixed pipe 41 , so that the rainwater 5 accumulated above the fixed pipe 41 can flow into the fixed pipe 41 through the through hole 42 .

[0017] The center of the spiral plate 43 is fixedly connected with a shaft 44; a ventilation slot 45 is provided at a downward position of the outer circumferential surface of the shaft 44. The function of the ventilation slot 45 is that after the rainwater 5 inside the fixed pipe 41 evaporates, part of the wind energy blowing from both sides of the fixed pipe 41 to the fixed pipe 41 flows into the gap of the spiral plate 43 near the middle position through the ventilation slot 45, so that the soil retained in the middle position of the spiral plate 43 is driven by the wind to be discharged through the through hole 42.

[0018] The end of the connecting pipe 3 close to the pipeline 2 is fixedly connected with an arc plate 31 located inside the pipeline 2. The arc plate 31 is used to change the wind direction of the wind flowing into the pipeline 2.

[0019] A plurality of air inlets 21 are arranged on the outer circumferential surface of the pipe 2 to facilitate the flow of outside air into the pipe 2.

[0020] A drainage trough 12 connected to the pipeline 2 is provided at the bottom of the steep slope 1 ; a water diversion trough 11 connected to the pipeline 2 is provided at the top of the steep slope 1 .

[0021] The cross section of the groove 13 is half of the cross section of the corresponding pipe 2 or fixed pipe 41. The pipe 2 and the fixed pipe 41 divide the steep slope 1 into multiple areas, and the fixed pipe 41 blocks the rainwater 5 from flowing downward to other areas, so as to avoid the rainwater 5 from gathering into a large flow of water during the downward flow, thereby reducing the scouring of the soil during the downward flow of the rainwater 5.

[0022] The diameter of the pipeline 2 is greater than the diameter of the connecting pipe 3 .

[0023] A method for using a mine steep slope ecological restoration device, the method comprising the following steps:

[0024] Step 1: When it rains, rainwater 5 on the upper plane of the steep slope 1 flows into the pipe 2 through the water diversion trough 11, and finally flows into the drainage trough 12 along the pipe 2 for discharge;

[0025] Step 2: When the rainwater 5 on the steep slope 1 flows downward to the position of the fixed pipe 41 , it will flow into the interior of the fixed pipe 41 through the through hole 42 , and then flow into the pipeline 2 along the connecting pipes 3 on both sides and be discharged.

[0026] The working principle of the present invention is: when it rains, rainwater 5 on the upper plane of the steep slope 1 flows into the pipe 2 through the water diversion groove 11, and finally flows into the drainage groove 12 along the pipe 2 for discharge;

[0027] When the rainwater 5 on the slope of the steep slope 1 flows downward to the position of the fixed pipe 41, since the depth of the groove 13 where the fixed pipe 41 is located is smaller than the fixed pipe 41, the fixed pipe 41 is partially exposed on the steep slope 1 to prevent the rainwater 5 from flowing downward, and a through hole 42 is provided on the fixed pipe 41, and the rainwater 5 accumulated at the fixed pipe 41 flows into the fixed pipe 41 through the through hole 42. Since the fixed pipe 41 drives the spiral plate 43 to be arranged in a horizontal direction, when the depth of the rainwater 5 in the fixed pipe 41 increases to exceed the width of the spiral plate 43, it flows through the gap between the spiral plates 43 until the gap between the spiral plates 43 in the lower half of the fixed pipe 41 is completely filled with rainwater 5, and the excess rainwater 5 flows into the connecting pipe 3. , and then discharged through the pipe 2. Since the rainwater 5 in the fixed pipe 41 flows in from the steep slope 1, it will be mixed with a small amount of soil. The spiral plate 43 can limit the rainwater 5 from being directly discharged into the connecting pipe 3. The rainwater 5 flowing into the fixed pipe 41 from the steep slope 1 will remain in the gap between the spiral plates 43, reducing the soil from flowing into the pipe 2 along with the rainwater 5. In addition, since the fixed pipe 41 is provided in the transverse groove 13 on the steep slope 1, the fixed pipe 41 is partially exposed at the upper end of the steep slope 1, so that the rainwater 5 can be discharged along the fixed pipe 41 at the upper end of each fixed pipe 41, reducing the rainwater 5 from gathering into a large water flow in the process of flowing downward, thereby avoiding the rainwater 5 from scouring the soil on the steep slope 1, thereby reducing soil loss;

[0028] After the rain stops, the outside air enters the pipe 2 through the air inlet 21, and then changes the wind direction after being blocked by the arc plate 31, so that the air flows into the fixed pipe 41, accelerates the evaporation of water in the fixed pipe 41, and accelerates the dehydration and drying of the soil retained in the fixed pipe 41. When the water in the fixed pipe 41 is completely evaporated, the outside wind enters the fixed pipe 41 through the air inlet 21, flows along the setting direction of the spiral plate 43, and finally flows out through the through hole 42. During the flow of wind, the soil in the gap of the spiral plate 43 is driven to move with the wind until it is discharged from the through hole 42 and falls back on the steep slope 1, which can not only further reduce soil loss, but also reduce the soil in the gap of the spiral plate 43, avoid excessive accumulation of soil, resulting in a decrease in the water storage capacity in the gap of the spiral plate 43, and affect subsequent soil interception.
