Description

Technical Field

[0001] This invention relates to the field of slope reinforcement technology, specifically to an ecological reinforcement structure for mine slopes and its construction process. Background Technology

[0002] Mine slope reinforcement refers to measures taken through engineering techniques to improve the stability of open-pit mine slopes. Its aim is to prevent geological disasters such as landslides and collapses, ensuring personnel safety and normal production. Effectively preventing casualties and equipment damage caused by slope instability is particularly significant in deep open-pit mines. Its core function is to enhance the integrity and anti-sliding capacity of the slope's rock and soil, reducing the risk of instability caused by changes in geological conditions or external loads.

[0003] Existing methods for reinforcing mine slopes cannot provide holistic reinforcement and protection of the slope surface, thus affecting slope stability and failing to achieve soil stabilization and ecological restoration. Therefore, they do not meet current needs. To address this, we propose an ecological reinforcement structure for mine slopes and its construction process. Summary of the Invention

[0004] The purpose of this invention is to provide an ecological reinforcement structure for mine slopes and its construction process, in order to solve the problems mentioned in the background art, that existing methods for reinforcing mine slopes cannot form an integral reinforcement and barrier on the slope surface, thereby affecting the stability of the mine slope, and at the same time failing to achieve soil stabilization and ecological restoration.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ecological reinforcement structure for mine slopes, comprising a spliced ​​staircase, wherein the spliced ​​staircase is composed of multiple slope reinforcement mechanisms, each of the slope reinforcement mechanisms comprising a T-shaped slope stabilization unit, wherein multiple horizontal anchor bolt units are installed at the front end of the T-shaped slope stabilization unit, and multiple vertical anchor bolt units are installed at the bottom end of the T-shaped slope stabilization unit, wherein the T-shaped slope stabilization unit comprises a T-shaped frame, wherein a first interlocking retaining strip and a second interlocking retaining strip are fixedly installed at both ends of the T-shaped frame, wherein an installation pressure plate is installed at the upper end of the T-shaped frame, and multiple retaining plates are installed between the T-shaped frame and the installation pressure plate, wherein multiple strip-shaped installation grooves are provided at the lower part of the rear end face of the T-shaped frame, wherein multiple first insertion columns are fixedly installed at the bottom end of the T-shaped frame, and multiple second insertion columns are fixedly installed at the front end of the T-shaped frame, and multiple directional installation through grooves are provided on the inner side of the front end of the T-shaped frame.

[0006] Preferably, both the vertical anchor bolt unit and the horizontal anchor bolt unit include an anchor bolt body. A limit ring is installed on the outer side of the upper end of the anchor bolt body, and multiple pull-out bars are rotatably connected to the outer side of the bottom end of the anchor bolt body. The multiple pull-out bars are arranged in a circle relative to the anchor bolt body, and the angle between the anchor bolt body and the multiple pull-out bars is an acute angle.

[0007] Preferably, the vertical anchor unit further includes a connecting pad that fits and contacts the lower end face of the limiting ring. The connecting pad is fitted onto the outside of the anchor body and fixedly connected to the T-shaped frame. The limiting ring is fixedly connected to the connecting pad.

[0008] Preferably, the plurality of vertical anchor bolt units and horizontal anchor bolt units are arranged linearly along the side of the T-shaped frame, and the plurality of vertical anchor bolt units and horizontal anchor bolt units are arranged in a one-to-one correspondence. The plurality of vertical anchor bolt units and horizontal anchor bolt units are respectively inserted into the inner side of the plurality of strip mounting grooves and directional mounting through grooves.

[0009] Preferably, the T-shaped frame, multiple first plug-in columns, and multiple second plug-in columns are integrally cast in concrete. The upper end of the T-shaped frame is provided with multiple U-shaped grooves arranged in a linear pattern. The retaining plate is inserted into the inner side of the U-shaped groove. The T-shaped frame and multiple retaining plates are fixedly connected by mounting pressure plates. Each retaining plate has multiple water-permeable holes on its outer surface.

[0010] Preferably, one side of the splicing steps is provided with a mine slope, and multiple slope reinforcement mechanisms are arranged linearly along the mine slope. The multiple slope reinforcement mechanisms are connected end to end, and adjacent T-shaped frames are interlocked and installed by a first interlocking stop bar and a second interlocking stop bar.

[0011] Preferably, the plurality of vertical anchor units are coaxial with the first plug-in post, and the anchor body of the vertical anchor unit passes through the limiting ring, the connecting pad and the first plug-in post and is plugged into the inner side of the mine slope. The horizontal anchor unit is coaxial with the second plug-in post, and the anchor body of the horizontal anchor unit passes through the T-shaped frame and the second plug-in post and is plugged into the inner side of the mine slope.

[0012] Preferably, the horizontal anchor unit is installed horizontally, and the angle between the vertical anchor unit and the horizontal anchor unit is an obtuse angle.

[0013] A construction process for an ecological reinforcement structure for mine slopes includes the following steps: S1: The T-shaped frame, multiple first interlocking columns, and multiple second interlocking columns are integrally cast using concrete. The T-shaped frame is then installed on the mine slope. First interlocking strips and second interlocking strips are installed at both ends of the T-shaped frame, so that each pair of adjacent T-shaped frames can be interlocked with each other through the first interlocking strips and the second interlocking strips, thereby improving the overall connection strength of the splicing steps and blocking rainwater from the mine slope. S2: At this time, multiple slope reinforcement mechanisms form a splicing ladder on the mine slope. By installing multiple splicing ladders on the mine slope from low to high, the mine slope can be fully reinforced. After the T-shaped slope reinforcement unit is installed, multiple vertical anchor units and horizontal anchor units are assembled simultaneously. S3: Specifically, multiple vertical anchor bolt units and horizontal anchor bolt units are respectively inserted into the inner side of multiple strip-shaped installation slots and directional installation through slots, so that the anchor bolt body in the vertical anchor bolt unit passes through the connecting pad and the first insertion post and is inserted into the inner side of the mine slope. At the same time, the anchor bolt body in the horizontal anchor bolt unit passes through the T-shaped frame and the second insertion post and is inserted into the inner side of the mine slope. Thus, the anchor bolt body can effectively maintain a stable connection with the mine slope through multiple pull-out strips. S4: The angle between the vertical anchor unit and the horizontal anchor unit is an obtuse angle. The T-frame can achieve the reinforcement effect of the mine slope through multiple vertical anchor units and multiple horizontal anchor units. The vertical anchor units are protected by the strip installation groove, which effectively prevents the vertical anchor units from being corroded by rainwater falling from the mine slope. S5: Simultaneously, the strip installation slot and directional installation through slot can provide installation space for vertical anchor bolt units and horizontal anchor bolt units. Multiple retaining plates are installed between the upper end of the T-shaped frame and the installation pressure plate, and each retaining plate has water permeable holes on its outer surface. Thus, the retaining plates facilitate water permeability between the upper end of the T-shaped frame and the mine slope when backfilling with soil, preventing soil loss and facilitating ecological stability restoration.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a first and a second interlocking strip to interlock and install each pair of adjacent T-shaped frames, thereby improving the overall connection strength of the splicing steps and blocking rainwater from the mine slope. Multiple slope reinforcement mechanisms form a splicing step on the mine slope. By installing multiple splicing steps sequentially from low to high on the mine slope, the mine slope can be fully reinforced. The anchor body can effectively maintain a stable connection with the mine slope through multiple pull-out strips, and the angle between the vertical anchor unit and the horizontal anchor unit is an obtuse angle. The T-shaped frame can achieve the reinforcement effect of the mine slope through multiple vertical anchor units and multiple horizontal anchor units. 2. This invention protects the vertical anchor bolt units by using strip-shaped installation grooves, effectively preventing rainwater from causing corrosion on the mine slope. Simultaneously, the strip-shaped installation grooves and directional installation channels provide installation space for both vertical and horizontal anchor bolt units. Each retaining plate has permeable holes on its outer surface, facilitating water permeability between the upper end of the T-shaped frame and the mine slope during soil backfilling, preventing soil erosion and promoting ecological restoration.

A mine slope is provided on one side of the spliced ​​staircase 1, and the multiple slope reinforcement mechanisms are arranged linearly along the mine slope and connected end to end. Each slope reinforcement mechanism includes a T-shaped slope reinforcement unit 2, which includes a T-shaped frame 201. A first interlocking baffle 202 and a second interlocking baffle 203 are fixedly installed at both ends of the T-shaped frame 201, respectively. Adjacent T-shaped frames 201 are interlocked with each other through the first interlocking baffle 202 and the second interlocking baffle 203, thereby improving the overall connection strength of the spliced ​​staircase 1 and blocking rainwater from the mine slope. A mounting plate 205 is installed on the upper end of the T-shaped frame 201. Multiple retaining plates 204 are installed between the T-shaped frame 201 and the mounting plate 205. Multiple U-shaped grooves arranged linearly are provided on the upper end of the T-shaped frame 201. The retaining plates 204 are inserted into the inner side of the U-shaped grooves. The T-shaped frame 201 and the multiple retaining plates 204 are fixedly connected by the mounting plate 205. The outer surface of each retaining plate 204 is provided with multiple water-permeable holes. The retaining plates 204 facilitate water permeability between the upper end of the T-shaped frame 201 and the mine slope when backfilling with soil, thereby preventing soil loss and facilitating ecological stability restoration. The lower part of the rear end face of the T-shaped frame 201 is provided with multiple strip-shaped installation slots 206. Multiple first plug-in posts 208 are fixedly installed at the bottom end of the T-shaped frame 201, and multiple second plug-in posts 209 are fixedly installed at the front end of the T-shaped frame 201. The T-shaped frame 201, the multiple first plug-in posts 208 and the multiple second plug-in posts 209 are integrally cast with concrete. The inner side of the front end of the T-shaped frame 201 is provided with multiple directional installation through slots 207. The vertical anchor bolt unit 3 is protected and installed through the strip-shaped installation slots 206, which effectively prevents the vertical anchor bolt unit 3 from being corroded by rainwater falling from the mine slope.

[0019] Please see Figures 3 to 5 The front end of the T-shaped slope stabilization unit 2 is equipped with multiple horizontal anchor bolt units 4, and the bottom end of the T-shaped slope stabilization unit 2 is equipped with multiple vertical anchor bolt units 3. The multiple vertical anchor bolt units 3 and horizontal anchor bolt units 4 are arranged linearly along the side of the T-shaped frame 201. The multiple vertical anchor bolt units 3 and horizontal anchor bolt units 4 are set one-to-one. The multiple vertical anchor bolt units 3 and horizontal anchor bolt units 4 are respectively inserted into the inner side of multiple strip installation slots 206 and directional installation through slots 207. The horizontal anchor bolt units 4 are installed horizontally, and the included angle between the vertical anchor bolt units 3 and the horizontal anchor bolt units 4 is an obtuse angle.

[0020] Please see Figures 4 to 6 Both the vertical anchor bolt unit 3 and the horizontal anchor bolt unit 4 include an anchor bolt body 501. A limit ring 502 is installed on the outer side of the upper end of the anchor bolt body 501. Multiple anti-pull strips 503 are rotatably connected to the outer side of the bottom end of the anchor bolt body 501. The multiple anti-pull strips 503 are arranged in a circle relative to the anchor bolt body 501. The angle between the anchor bolt body 501 and the multiple anti-pull strips 503 is an acute angle. The anchor bolt body 501 can effectively maintain a stable connection with the mine slope through the multiple anti-pull strips 503. The vertical anchor unit 3 also includes a connecting pad 301 that is in contact with the lower end face of the limiting ring 502. The connecting pad 301 is fitted onto the outside of the anchor body 501 and fixedly connected to the T-shaped frame 201. The limiting ring 502 is fixedly connected to the connecting pad 301. The multiple vertical anchor units 3 are coaxial with the first insertion post 208. The anchor body 501 in the vertical anchor unit 3 passes through the limiting ring 502, the connecting pad 301 and the first insertion post 208 and is inserted into the inner side of the mine slope. The horizontal anchor unit 4 is coaxial with the second insertion post 209. The anchor body 501 in the horizontal anchor unit 4 passes through the T-shaped frame 201 and the second insertion post 209 and is inserted into the inner side of the mine slope, so that the T-shaped slope stabilization unit 2 can maintain stable installation through the multiple vertical anchor units 3 and the multiple horizontal anchor units 4.

[0021] A construction process for an ecological reinforcement structure for mine slopes includes the following steps: S1: The T-shaped frame 201, multiple first insertion columns 208 and multiple second insertion columns 209 are integrally cast using concrete. Then, the T-shaped frame 201 is installed on the mine slope. First interlocking strips 202 and second interlocking strips 203 are installed at both ends of the T-shaped frame 201, so that each two adjacent T-shaped frames 201 are interlocked with each other by the first interlocking strips 202 and the second interlocking strips 203, which improves the overall connection strength of the splicing ladder 1 and blocks rainwater from the mine slope. S2: At this time, multiple slope reinforcement mechanisms form a splicing ladder 1 on the mine slope. By installing multiple splicing ladders 1 sequentially from low to high on the mine slope, the mine slope can be fully reinforced. After the T-shaped slope reinforcement unit 2 is installed, multiple vertical anchor bolt units 3 and horizontal anchor bolt units 4 are assembled simultaneously. S3: Specifically, multiple vertical anchor bolt units 3 and horizontal anchor bolt units 4 are respectively inserted into the inner side of multiple strip mounting slots 206 and directional mounting through slots 207, so that the anchor bolt body 501 in the vertical anchor bolt unit 3 passes through the connecting pad 301 and the first insertion post 208 and is inserted into the inner side of the mine slope. At the same time, the anchor bolt body 501 in the horizontal anchor bolt unit 4 passes through the T-shaped frame 201 and the second insertion post 209 and is inserted into the inner side of the mine slope. Thus, the anchor bolt body 501 can effectively maintain a stable connection with the mine slope through multiple pull-out strips 503. S4: The angle between the vertical anchor unit 3 and the horizontal anchor unit 4 is an obtuse angle. The T-shaped frame 201 can achieve the reinforcement effect of the mine slope through multiple vertical anchor units 3 and multiple horizontal anchor units 4. The vertical anchor unit 3 is protected by the strip installation groove 206, which effectively prevents the vertical anchor unit 3 from being corroded by rainwater falling from the mine slope. S5: Simultaneously, the strip-shaped installation groove 206 and the directional installation through groove 207 can provide installation space for the vertical anchor bolt unit 3 and the horizontal anchor bolt unit 4. Multiple retaining plates 204 are installed between the upper end of the T-shaped frame 201 and the installation pressure plate 205, and each retaining plate 204 has water-permeable holes on its outer surface. Thus, the retaining plates 204 facilitate water permeability between the upper end of the T-shaped frame 201 and the mine slope when backfilling with soil, avoiding soil loss and facilitating ecological stability restoration.
