Description

Technical Field

[0001] The utility model relates to the technical field of mine pit backfill repair and anti-seepage, in particular to a mine pit steep slope anti-seepage system based on high molecular polymer mineral anti-seepage materials. Background Art

[0002] Mine pits are formed during the mining process of mineral resources. At present, the main method of repairing mine pits is backfilling. At present, solid waste is used to fill the mine pits, but there is a problem of seepage pollution of pollutants, so anti-seepage treatment is required. At present, the conventional treatment of steep slopes in mine pits mainly adopts engineering measures such as excavation, backfilling, and mesh spraying on steep rock slopes to achieve the construction conditions for laying anti-seepage membranes.

[0003] There are many deficiencies in the existing technology, such as extremely high requirements for the anti-seepage foundation layer of the mine slope, great construction difficulty, large earthwork volume, high project investment, high requirements for slope geology, and easy occurrence of problems such as settlement and deformation of the anti-seepage layer of the slope or local instability of the surface layer of the slope. For example, the Chinese patent with publication number CN112523264A uses the hanging mesh spraying technology to level and passivate the slope base before paving, which has problems such as high construction cost, great difficulty and great hidden dangers of the spraying layer; the Chinese patent with publication number CN217782093U needs to process the slope to improve the anti-skid stability of the protective structure and the anti-seepage membrane, which has problems such as complex construction technology, great excavation difficulty, and slope disturbance instability.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 present invention, rather than all of the embodiments.

[0019] Reference Figure 1-2A mine steep slope anti-seepage system based on high molecular polymer mineral anti-seepage materials includes a drainage mechanism, a drainage guide mechanism, an anti-seepage mechanism and an anchoring mechanism arranged on the mine steep slope 1. Each mechanism cooperates with each other to achieve effective anti-seepage of the mine steep slope 1.

[0020] The drainage mechanism is the basic component of the whole system, which includes a blind ditch 3 set on the steep slope 1 of the mine. The blind ditch 3 can effectively gather and guide water flow. Inside the blind ditch 3, there is a prefabricated drainage blind ditch block 4 that fits tightly and tightly. This design minimizes the possibility of water leakage. The prefabricated drainage blind ditch block 4 is equipped with an efficient and reliable pumping component 5. The pumping component 5 consists of a high-performance pump and precision pipes, which can quickly and effectively pump out the accumulated water in the blind ditch 3 to ensure the timeliness and effectiveness of drainage.

[0021] The drainage mechanism plays a key role in water diversion in the system, including the inner geocell 6 and the drainage pipe 7 set on the steep slope 1 of the mine. The inner geocell 6 is reasonably positioned and arranged, and the graded pebbles filled inside it are strictly screened, with a uniform particle size of 40 mm. This specific particle size of graded pebbles can ensure that the inner geocell 6 has good porosity and permeability, allowing water to pass smoothly and achieve efficient water diversion. One end of the drainage pipe 7 is precisely extended into the steep slope 1 of the mine, and the other end is precisely extended into the inner geocell 6, forming a coherent water diversion channel. The drainage pipes 7 are arranged at different heights of the steep slope 1 of the mine. This careful arrangement can comprehensively collect seepage water from different parts. Moreover, the upward inclination angle of the drainage pipe 7 relative to the horizontal plane is precisely controlled to be 5°. This subtle angle design is conducive to the self-flow discharge of water under the action of gravity, greatly reducing the drainage resistance and significantly improving the drainage efficiency.

[0022] The anti-seepage mechanism is an important barrier to prevent water infiltration, including an outer geocell 2 set on the steep slope 1 of the mine. The outer geocell 2 is filled with a high-molecular polymer mineral anti-seepage material with excellent performance. It is a material used in anti-seepage engineering with good anti-seepage performance and chemical stability. This material has excellent anti-seepage performance, can effectively block the infiltration of external moisture, and provides reliable protection for the steep slope 1 of the mine. The laying of the outer geocell 2 and the inner geocell 6 starts from the bottom of the slope foot of the steep slope 1 of the mine. The laying process is rigorous and orderly, advancing upward layer by layer, and carefully laying each step to ensure that the entire slope is covered without omission, forming a continuous and solid anti-seepage layer.

[0023] The anchoring mechanism provides stable support and fixation for the entire system, including the T-shaped anchor rod 8 installed on the steep slope 1 of the mine pit. The T-shaped anchor rod 8 adopts advanced drilling and grouting technology to be firmly anchored on the steep slope 1 of the mine pit. The length of the T-shaped anchor rod 8 is 1.2m, which can ensure that the anchor rod has sufficient anchoring depth in the steep slope 1 of the mine pit, thereby providing a strong and stable anchoring force. At the same time, the T-shaped anchor rod 8 is perpendicular to the direction of the steep slope 1 of the mine pit. This vertical arrangement can maximize the anchoring effect, effectively prevent the displacement or deformation of each mechanism during use, and ensure the stability and reliability of the entire system.

[0024] Working principle of the utility model: First, the drainage mechanism starts to work. The dark ditch 3 on the steep slope 1 of the mine pit effectively gathers the water flow from the slope surface, and the prefabricated drainage dark ditch block 4 that fits tightly inside it minimizes the possibility of water leakage to the surrounding. The pumping assembly 5 in the prefabricated drainage dark ditch block 4 is composed of a high-performance pump and precision pipes, which can quickly and effectively pump out the accumulated water in the dark ditch 3, ensuring the timeliness and effectiveness of drainage, avoiding the accumulation of accumulated water at the foot of the slope, and reducing the adverse effects of water pressure on the slope. Then, the drainage mechanism comes into play. The inner geocell 6 set on the steep slope 1 of the mine pit has good porosity and permeability due to the 40mm graded pebbles filled inside, so that the water flow on the slope surface can pass smoothly, realizing efficient water diversion. One end of the drainage pipe 7 extends into the steep slope 1 of the mine pit to collect seepage from different parts, and the other end extends into the inner geocell 6 to form a coherent water diversion channel. Moreover, the drainage pipes 7 arranged at different heights of the steep slope 1 of the mine pit are designed to be inclined upward at 5° relative to the horizontal plane, which uses gravity to allow water to flow out by itself, greatly reducing drainage resistance, significantly improving drainage efficiency, and avoiding the accumulation of water inside the slope. Then, the anti-seepage mechanism plays a key anti-seepage role. Then, the backfill material 9 composed of graded pebbles is filled to the bottom surface to make it flush, and then the outer geocell 2 is carefully laid upward layer by layer and on each step to form a continuous cover. The high-molecular polymer mineral anti-seepage material filled inside the outer geocell 2, with its excellent anti-seepage performance, effectively blocks the infiltration of external moisture, provides reliable protection for the steep slope 1 of the mine pit, and ensures the dryness and stability of the inside of the mine pit. Finally, the anchoring mechanism provides stable support and fixation for the entire system. The T-shaped anchor rod 8 installed on the steep slope 1 of the mine pit is firmly anchored in the steep slope 1 of the mine pit through advanced drilling and grouting technology. The length of 1.2m ensures that the anchor rod has sufficient anchoring depth in the steep slope 1 of the mine pit, providing a strong and stable anchoring force. The T-shaped anchor rod 8 is arranged perpendicular to the direction of the steep slope 1 of the mine pit, maximizing the anchoring effect, effectively preventing the displacement or deformation of the drainage mechanism, drainage guide mechanism and anti-seepage mechanism due to various forces during use, thereby ensuring the stability and reliability of the entire system, so that the entire system can function effectively for a long time.

[0025] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent substitutions or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
