Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of environmental remediation equipment, and particularly relates to an ecological remediation treatment device and method for green mine construction. BACKGROUND

[0002] When ecological remediation treatment is performed on abandoned mines, planting grass and trees is one of ecological remediation measures, different types of plants are planted in different regions of the abandoned mine, which can enhance the water and soil conservation capacity of the abandoned mine region and improve the ecological environment of the abandoned mine imperceptibly. For the steep slope region of the abandoned mine, since the rocks are exposed and the soil is scarce, and the working environment is relatively harsh, it is suitable to plant herbaceous or low shrub species. According to the specific construction process, the plants can be planted by the methods of guest soil spray seeding and net hanging, grass planting bag planting and the like. In the guest soil spray seeding and net hanging process, since the operation difficulty is low and the environmental adaptability is strong, the process is widely used in mine steep slope remediation operation. In order to enhance the fixing effect of the soil and the grass seeds in the spray seeding and net hanging process, the spatial structure of the three-dimensional net is used to enhance the fixing effect of the soil and the grass seeds, thereby reducing the influence of rainwater erosion on the steep slope after operation. However, in the initial stage after spray seeding, the soil and grass seeds on the three-dimensional net are still not ideal in terms of loss under the erosion of rainwater, which causes the ecological remediation operation of the steep slope to be not ideal.

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application will be further described below in combination with specific embodiments.

[0044] As shown in Figures 1 to 11 , the ecological restoration management device for green mine construction of the present application comprises a slope net 1 and an anchor rod 11, the slope net 1 is covered on a mine steep slope, the anchor rod 11 is fixedly installed on the mine steep slope, and the slope net 1 is fixedly connected with the anchor rod 11;

[0045] It also comprises an anti-erosion assembly, the anti-erosion assembly is fixedly installed on the slope net 1, and the anti-erosion assembly is used for blocking rainwater from eroding the slope net 1;

[0046] The anti-erosion assembly comprises an installation pad 2, the installation pad 2 is fixedly installed on the slope net 1 at equal intervals;

[0047] The anti-erosion assembly comprises an installation pad 2, the installation pad 2 is fixedly installed on the slope net 1 at equal intervals;

[0048] The anti-erosion assembly comprises an installation pad 2, the installation pad 2 is fixedly installed on the slope net 1 at equal intervals;

[0049] The anti-erosion assembly comprises an installation pad 2, the installation pad 2 is fixedly installed on the slope net 1 at equal intervals;

[0050] The anti-erosion piece 21 is made of slow-permeation fiber material, and the anti-erosion piece 21 is rolled into an incomplete cylindrical structure, and the incomplete cylindrical structure is designed to be open upward;

[0051] After the mine is abandoned, because the land is barren and the soil is scarce, when green plants are used for repair and treatment, usually, the guest soil needs to be filled, and for high and steep slope, because of the geographical environment restriction, the soil fixation is difficult, therefore, when the high and steep slope is treated, usually, the herbaceous, low shrub plants with low soil demand are planted, and the net spraying technology greatly reduces the difficulty of the high and steep slope grass planting process, and in order to further enhance the rainwater resistance of the soil, grass seeds and the like fixed on the steep slope, the anti-scouring assembly is arranged on the slope net 1, the rainwater scouring resistance is enhanced, the loss degree of the soil and the like sprayed on the mine steep slope is reduced, and then the treatment rate of the steep slope is accelerated;

[0052] Specifically, in the steep slope treatment, the artificial treats the steep slope of the treatment area, in the cleaning process, gradually remove the protruding, loose rock and other objects, to avoid the rock falling in the later stage to cause security risks, but also to a certain extent, the flattening of the steep slope, paving the way for the subsequent slope net 1, then the staff on the pre-planned anchoring point drilling anchor hole slot, and the anchor rod 11 is installed in the anchor hole slot, and adopts the concrete pouring and other fixed means, the anchor rod 11 is stably fixed on the steep slope, then the slope net 1 is gradually unfolded, hung from the top of the steep slope, when hanging, the slope net 1 is hung on the anchor rod 11, the evenly distributed anchor rod 11 is used to fix the slope net 1, and the steel wire, rope and other components are used to reinforce the fixed position of the slope net 1 and the anchor rod 11. It should be noted that the slope net 1 used in the present application can be a three-dimensional net, a wire mesh, or a composite net formed by stacking a three-dimensional net and a wire mesh. Since the anti-erosion assembly has been manufactured and connected to the slope net 1 during the manufacturing process of the slope net 1, the staff can adjust the anti-erosion assembly installed on the slope net 1 simultaneously when the slope net 1 is hung. After the slope net 1 is hung, the anti-erosion sheets 21 arranged at equal intervals on the slope net 1 are in an incomplete cylindrical structure under the support of the elastic support, i.e., the anti-erosion sheets 21 are in an incomplete circular shape, and since the anti-erosion sheets 21 are rolled upward, the incomplete cylindrical shape formed by the anti-erosion sheets 21 is open upward. After the anti-erosion sheets 21 are rolled, the slope net 1 is exposed, and since the anti-erosion sheets 21 are in a three-dimensional shape, the exposed area of the slope net 1 is large. At this time, the staff sprays the slurry mixed with soil, grass seeds, nutrients and other substances onto the slope net 1 with the cooperation of the spraying machine. Under the adhesion of the slurry itself and the interception of the structure of the slope net 1, the slurry is fixed on the steep slope. It should be noted that during the spraying process, since the anti-erosion sheets 21 are in a cylindrical shape, the range of the anti-erosion sheets 21 adhering to the slope net 1 is small. After adjusting the spraying angle of the slurry, the slurry can be sprayed on the slope net 1 as much as possible. After the spraying of the slurry is completed, the grass seeds can grow and develop. During this process, when the weather turns cloudy and it rains, the raindrops fall on the slope net 1 and the anti-erosion sheets 21. When the rainfall is small, the rainwater is absorbed by the soil sprayed on the slope net 1, providing water for the growth of grass. When the rainfall is large, the water flows into the soil, increasing the water content of the soil. Under the action of gravity, the excess water gradually flows downward, gradually entering the cylindrical structure surrounded by the anti-erosion sheets 21 and the bag-shaped structure formed by the interception ring sheet 22 and the anti-erosion sheets 21. As the amount of water and soil entering the cylindrical structure increases, the elastic support deforms gradually under the action of gravity, causing the anti-erosion sheets 21 to gradually unfold. On the one hand, as the unfolding degree of the anti-erosion sheets 21 increases, the covering degree of the anti-erosion sheets 21 to the slope net 1 gradually increases,Further gradually reduce the rain on the slope of the soil on the net 1 erosion, on the other hand, with the anti-erosion piece 21 gradually unfolded, the bottom of the bag-shaped structure formed by the interception of the piece and the anti-erosion piece 21 is lower, resulting in the probability of water flowing into its interior is greater, further accelerate the expansion speed of the anti-erosion piece 21, and finally the anti-erosion piece 21 is completely unfolded, and when the rain becomes small until stop, the intercepted rain in the bag-shaped structure formed by the interception ring piece 22 and the anti-erosion piece 21, then slowly infiltrate the anti-erosion piece 21, continuously supplement the water for the grass on the slope net 1, until the water loss, at this time, under the action of the elastic support, the anti-erosion piece 21 is rolled again, facilitating the grass to replenish the light.

[0053] The present application is provided by setting the anti-erosion assembly, by using the weight of rain in heavy rain, forcing the anti-erosion assembly to unfold, and further providing a barrier for the soil on the slope net 1, reducing the erosion of the soil sprayed on the slope by rain, improving the efficiency of planting grass, and the existence of the anti-erosion piece 21 with water and soil interception function can also realize the water and soil fixation function to a certain extent, further enhance the fixation effect of the sprayed soil and grass seeds, and accelerate the repair and management rate of the steep slope of the mine.

[0054] As a preferred embodiment of the present application, the elastic support is composed of an elastic metal sheet 23 and a telescopic strip 24, the elastic metal sheet 23 is fixedly attached to the anti-erosion piece 21, and the telescopic strip 24 is fixedly connected to the elastic metal sheet 23 at one end and to the mounting pad 2 at the other end.

[0055] The telescopic strip 24 is made of water-absorbing and swelling rubber material;

[0056] The elastic support is made of an elastic metal sheet 23 and a telescopic strip 24, and the telescopic strip 24 is made of water-absorbing and swelling rubber material, so that when it is not raining, the water content of the telescopic strip 24 is low, and at this time, the length of the telescopic strip 24 is small, under the pulling action of the telescopic strip 24 and the elastic action of the elastic metal sheet 23, the elastic metal sheet 23 and the anti-erosion piece 21 form a cylindrical structure, and due to the support of the elastic metal sheet 23, the cylindrical structure is close to a regular circle, and when it rains, the telescopic strip 24 gradually absorbs water and swells, the length of the telescopic strip 24 increases, and under the elastic recovery action of the elastic metal sheet 23, the elastic metal sheet 23 and the anti-erosion piece 21 gradually unfold, and finally form a sheet structure, which shields and protects the slope net 1, and cooperates with the pulling and pressing action of the weight of rain to accelerate the unfolding rate of the anti-erosion piece 21, and further reduce the erosion effect of the rain on the sprayed soil and other objects.

[0057] As a preferred embodiment of the present application, the fixing bolt 25 is installed on the mounting pad 2, the anti-scouring sheet 21 and the elastic metal sheet 23 are fixedly installed on the mounting pad 2 through the fixing bolt 25, the fixing bolt 25 and the elastic metal sheet 23 away from the slope net 1 are provided with the connecting groove 27, and the telescopic strip 24 is fixedly installed with the fastening bolt 26 at both ends, and the telescopic strip 24 is detachably fixedly connected with the elastic metal sheet 23 and the anti-scouring sheet 21 through the fastening bolt 26 and the connecting groove 27.

[0058] The fixing bolt 25 is arranged to enhance the superimposed fixing effect of the mounting pad 2, the anti-scouring sheet 21 and the elastic metal sheet 23, so as to avoid the anti-scouring assembly from falling off the slope net 1, and the connecting groove 27 and the fastening bolt 26 are arranged to detachably connect the telescopic strip 24 with the elastic metal sheet 23 and the anti-scouring sheet 21, so that the telescopic strip 24 is not assembled after the manufacturing is completed, at this time, the elastic metal sheet 23 is not subjected to external force and is in a straight sheet structure, which is convenient for folding and winding the slope net 1, and before use, the workers assemble the telescopic strip 24 on the elastic metal sheet 23 and the anti-scouring sheet 21 through the fastening bolt 26, so as to wind the elastic metal sheet 23 and the anti-scouring sheet 21, thereby enhancing the use convenience of the device.

[0059] As a preferred embodiment of the present application, the overturning net 3 is fixedly installed on the side wall of the mounting pad 2, and the overturning net 3 is fixedly installed with the traction cable 31 away from the mounting pad 2, and two adjacent traction cables 31 are fixedly connected with each other.

[0060] The overturning net 3 extends upward away from the mounting pad 2, the overturning net 3 is made of flexible three-dimensional net material, and in the initial state, the overturning net 3 deflects downward under the action of gravity, and the overturning net 3 sheet shields the corresponding anti-scouring sheet 21;

[0061] In order to further enhance the fixing effect of the mixed slurry of the sprayed soil and the grass seed, the overturning net 3 is arranged between the adjacent two installation pads 2, and the bottom end of the overturning net 3 is fixedly connected with the installation pad 2. After the slope net 1 is hung, the overturning net 3 is overturned downward under the action of gravity. On the one hand, the overturning net 3 shields the cylindrical anti-scouring sheet 21, and when the slurry is sprayed, the probability of the slurry being sprayed on the anti-scouring sheet 21 is reduced. On the other hand, the anti-scouring sheet 21 supports the overturning net 3, so that the overturning net 3 is unfolded in space, cooperates with the slope net 1, and increases the slurry spraying and adhering area. After the slurry is sprayed, the staff manually pulls the traction cable 31. Under the pulling of the traction cable 31, the overturning net 3 gradually fits the slope net 1, and at this time, the adhering surface of the slurry on the overturning net 3 and the slope net 1 is located between the overturning net 3 and the slope net 1. On the one hand, compared with direct surface spraying, the design of this place increases the depth of the slurry, which is convenient for fixing the slurry. It should be known that in other embodiments of the present application, the overturning net 3 can be sprayed again after overturning, further increasing the fixed thickness of the slurry on the slope. On the other hand, under the interception of the overturning net 3, the probability of the slurry being washed off the overturning net 3 and the slope net 1 is reduced.

[0062] As a preferred embodiment of the present application, the anchor rod 11 is fixedly installed with a wire ring 4 through a clamp. A tapered groove 41 is formed in the inner wall of the wire ring 4. Symmetrically designed friction blocks 42 are elastically installed in the tapered groove 41 through springs 43. The traction cable 31 passes through the gap between the friction blocks 42. The wire ring 4 is used for one-way locking of the traction cable 31.

[0063] The installation pad 2, the anti-scouring sheet 21 and the width are all less than the width of the slope net 1. The edges of the adjacent two groups of slope nets 1 are overlapped;

[0064] By installing the wire ring 4, when the traction cable 31 is not pulled, the excessive length of the traction cable 31 is large, so that the overturning net 3 is not limited. When the traction cable 31 is pulled upward, under the action of friction, the friction blocks 42 push the springs 43 to move upward. When the traction cable 31 has a downward moving trend, the friction blocks 42 move to the bottom end of the tapered groove 41. Under the limitation of the tapered groove 41, the friction blocks 42 gradually approach, thereby increasing the friction force on the traction cable 31, and further one-way locking the traction cable 31. After the overturning net 3 fits the slope net 1, the overturning net 3 cannot be overturned again. At this time, under the action of the traction cable 31 and the wire ring 4, the overturning net 3 is indirectly connected with the anchor rod 11, cooperates with the anchor rod 11 to fix the slope net 1, and further enhances the fixing effect of the device on the slope.
