[0002] In the treatment of fractured rock slopes, the geological structure of fractured rock slopes is mainly characterized by faults, with northeast and northwest trending faults dominating, and small faults are relatively well-developed underground. In terms of regional structure, fault structures are relatively well-developed, especially extensional normal faults, which cut longitudinally and transversely. The main faults near the working area are the Sijiaofang Fault and the Nanding Fault.

[0003] For example, Chinese invention patent No. 2020111876772 discloses a support structure for fractured rock slopes. By laying two layers of concrete on the fractured rock slope, the overall stability and firmness of the support device are enhanced through dual measures. At the same time, a waterproof layer is set between the two concrete layers to prevent external water from entering the first concrete layer, making the support device extremely stable.

The motor, gears, and chain assembly are assembled. The gears are fixedly mounted on the shaft of the motor and mesh with the outer side of the chain in the chain assembly. The motor of the power assembly B113 is fixedly mounted on the upper baffle of the support assembly 112. The gears on both sides of the chain assembly have threaded holes in the middle. The threaded holes of the gears on both sides of the chain assembly of the power assembly B113 are threaded onto the threaded rod 111. The gears on both sides of the power assembly B113 are movably mounted in the grooves of the upper baffle of the support assembly 112. The control plate A114 is fixedly mounted on the upper end of the support assembly 112. The control plate A114 works in conjunction with the support rod B308 to push the support rod B308 open.Specifically, the motor of power unit A108 drives the lead screws on both sides of lead screw assembly 107 to rotate, which in turn moves the movable sleeve 106 to a designated position. This, in turn, moves the connecting collar 105 to a designated position, which in turn moves the connecting rod A104 to push the clamping plate 101 to tilt at a certain angle according to the actual situation. The motor of power unit B113 starts, driving the gears of power unit B113 to rotate, which in turn drives the chain assembly of power unit B113 to rotate. This, in turn, moves the threaded rod 111, which in turn moves the clamping plate 101 to a designated position. The threaded rod 111 cooperates with the connecting rod A104 to ensure that the clamping plate 101 is in close contact with the rock wall surface, pressing the clamping plate 101 firmly against the rock wall to prevent rock wall collapse during construction. After use, power units B113 and A108 are reversed to restore the equipment.

[0041] In one optional embodiment of the present invention, in addition to the same parts as in the previous embodiment, the anti-falling part 2 includes: an anti-falling rod 201, a base plate B202, a perforated support plate A203, a perforated support plate B204, a fixing post 205, a sprocket set A206, and a wheel B207.

Specifically, the entire equipment is pushed to the designated position, and the side of the perforated support plate B204 contacts the rock wall. According to the actual situation, multiple steep slope clamping parts 1, anti-falling parts 2, and support parts 3 are connected by connecting rods. There is a certain distance between the two steep slope clamping parts 1, anti-falling parts 2, and support parts 3. Rotating the control wheel of the sprocket set A206 drives the sprocket set A206 to rotate, thereby driving the fixed column 205 to move, so that the lower end of the fixed column 205 is in close contact with the ground, thereby fixing the equipment in the designated position on the ground through the fixed column 205.

[0043] When a rock falls from the rock face and lands on the fall arresting bar 201, it presses down on the bar. The spring at the bottom of the fall arresting bar 201, the perforated connecting block 305, and the cylindrical pad 306 reduce the potential energy of the falling rock, weakening its impact. This allows the rock to slide off the fall arresting bar 201 to the bottom of the rock face and accumulate, preventing it from injuring people below.

[0044] In one optional embodiment of the present invention, in addition to the same parts as in the previous embodiment, the support part 3 includes: control plate B301, control plate C302, support rod A303, adjusting block 304, connecting block with holes 305, cylindrical pad 306, connecting plate C307, support rod B308, lower baffle 309, and telescopic rod 310.

[0045] The upper end of the control board B301 is a baffle, and shafts are installed at both ends on one side of the baffle. The lower parts of the shafts on both sides of the control board B301 are fixedly installed in the holes of the perforated connecting block 305. The shaft at the lower part of the control board C302 is rotatably installed in the hole at the upper end of the support rod A303. The upper part of the support rod A303 is slidably installed in the hole of the adjusting block 304. A spring is installed on the outer side of the upper part of the support rod A303, and the spring is connected to the adjusting block 304. The hole on one side of the adjusting block 304 is rotatably installed on the upper part of the lead screw assembly 107. The connecting shaft is mounted on the connecting block 305; the holes on both sides of the connecting block 305 are fixedly installed on the lower part of the shaft of the control board B301. There are two connecting blocks 305 with holes, and there is a certain distance between them; the shaft on one side of the cylindrical pad 306 is slidably installed in the groove on the side of the connecting block 305 with holes, and the end of the shaft on the side of the cylindrical pad 306 is connected to the bottom of the groove on the side of the connecting block 305 with holes by a spring; the connecting plate C307 is fixedly installed on the rear side of the lower connecting block 305 with holes, and the connecting plate C307 is fixedly installed on the rear side of the lower connecting block 305 with holes. 07 has a groove on one side, and a shaft is installed in the groove; one end of the support rod B308 is rotatably mounted on the shaft of the connecting plate C307, and the side of the support rod B308 contacts the control plate A114, through which the control plate A114 tilts the support rod B308; the upper end of the lower baffle 309 is fixedly mounted on the lower end of the connecting block 305 with holes; the upper end of the telescopic rod 310 is fixedly mounted on the baffle below the lower baffle 309, and the lower end of the telescopic rod 310 is fixedly mounted on the base plate A109; specifically, the telescopic rod 3... 10. The retraction causes the lower baffle 309 to move downward, thereby causing the perforated connecting block 305 and control plate B301 to move downward. The downward movement of the perforated connecting block 305 causes the cylindrical pad 306 to move, so that the cylindrical pad 306 is placed behind the anti-fall bar 201. The anti-fall bar 201 pushes the cylindrical pad 306 into the groove of the perforated connecting block 305. The cylindrical pad 306 is placed behind the anti-fall bar 201, supporting the anti-fall bar 201 so that the anti-fall bar 201 can maintain its original shape when subjected to the impact force of the stone.

[0046] The control panel B301 moves down, pushing the control panel C302 down, thereby pushing the support rod A303 to overcome the tension of the spring. Under the restriction of the adjusting block 304, the bottom of the support rod A303 is pressed into the soil, so that the support rod A303 supports the equipment. The perforated connecting block 305 moves down, causing the connecting plate C307 to move down. Under the action of the control panel A114, the support rod B308 tilts, inserting the bottom end of the support rod B308 into the soil, so that the support rod B308 supports the equipment.

[0047] After the equipment is used, the telescopic rod 310 is pushed out, causing the lower baffle 309 to move upward, which in turn causes the control board B301 and the perforated connecting block 305 to move upward. Then, the cylindrical pad 306 returns to its original shape under the action of the spring, and the support rod A303 returns to its original shape under the action of the spring. The support rod A303 is then retracted, and the perforated connecting block 305 moves upward, causing the support rod B308 to move upward, which in turn causes the support rod B308 to detach from the ground.

[0048] A protection method for fractured rock slopes, characterized by comprising the following steps:

[0049] a. First, push the entire equipment to the designated position and fix it in place. Then, connect the multiple steep slope clamping parts, anti-falling parts, and support parts with connecting rods according to the actual situation.

[0050] b. Adjust the clamping plate to ensure it is in close contact with the rock wall and firmly pressed against the rock wall to prevent the rock wall from collapsing during construction;

[0051] c. Insert the lower ends of support rods A and B into the soil to fix and support the equipment, preventing the equipment from tilting due to stress on the income meter and causing it to lose its function;

[0052] d. When a rock falls from the rock face onto the fall arresting bar, the spring reduces the impact force of the rock, allowing it to slide off the fall arresting bar to the bottom of the rock face and accumulate.

[0053] e. Once this section of construction is completed, the equipment can be moved to a new location for further work.

[0054] Working principle: Push the entire equipment to the designated position, and the side of the perforated support plate B204 contacts the rock wall. According to the actual situation, connect multiple steep slope clamping parts 1, anti-falling parts 2, and support parts 3 through connecting rods. There is a certain distance between two steep slope clamping parts 1, anti-falling parts 2, and support parts 3. Rotate the control wheel of the sprocket set A206 to drive the sprocket set A206 to rotate, thereby driving the fixed column 205 to move, so that the lower end of the fixed column 205 makes close contact with the ground, thereby fixing the equipment in the designated position on the ground through the fixed column 205.

[0055] The retraction of the telescopic rod 310 causes the lower baffle 309 to move downward, thereby causing the perforated connecting block 305 and the control plate B301 to move downward. The downward movement of the perforated connecting block 305 causes the cylindrical pad 306 to move, so that the cylindrical pad 306 is placed behind the anti-fall rod 201. The anti-fall rod 201 pushes the cylindrical pad 306 into the groove of the perforated connecting block 305. The cylindrical pad 306 is placed behind the anti-fall rod 201, supporting the anti-fall rod 201 so that the anti-fall rod 201 can maintain its original shape when subjected to the impact force of stones.

[0056] The control panel B301 moves down, pushing the control panel C302 down, thereby pushing the support rod A303 to overcome the tension of the spring. Under the restriction of the adjusting block 304, the bottom of the support rod A303 is pressed into the soil, so that the support rod A303 supports the equipment. The perforated connecting block 305 moves down, causing the connecting plate C307 to move down. Under the action of the control panel A114, the support rod B308 tilts, inserting the bottom end of the support rod B308 into the soil, so that the support rod B308 supports the equipment.

[0057] After the equipment is used, the telescopic rod 310 is pushed out, which drives the lower baffle 309 to move upward, thereby driving the control board B301 and the perforated connecting block 305 to move upward. Then, the cylindrical pad 306 returns to its original shape under the action of the spring, and the support rod A303 returns to its original shape under the action of the spring. The support rod A303 is then retracted, and the perforated connecting block 305 moves upward, which drives the support rod B308 to move upward, thereby causing the support rod B308 to detach from the ground.

[0058] The motor of power unit A108 drives the lead screws on both sides of lead screw assembly 107 to rotate, which in turn moves the movable sleeve 106 to a designated position. This moves the connecting collar 105 to a designated position, which in turn moves the connecting rod A104 to push the clamping plate 101 to tilt at a certain angle according to the actual situation. The motor of power unit B113 starts, which drives the gear of power unit B113 to rotate, which in turn drives the chain assembly of power unit B113 to rotate. This drives the threaded rod 111 to move, which in turn moves the clamping plate 101 to a designated position. The threaded rod 111 cooperates with the connecting rod A104 to ensure that the clamping plate 101 is in close contact with the rock wall surface, pressing the clamping plate 101 firmly against the rock wall to prevent the rock wall from collapsing during construction. After use, power units B113 and A108 are reversed to restore the equipment.

[0059] When a rock falls from the rock face and lands on the fall arresting bar 201, it presses down on the fall arresting bar 201. Under the action of the spring at the bottom of the fall arresting bar 201, the perforated connecting block 305, and the cylindrical pad block 306, the potential energy of the falling rock is reduced, the impact force of the rock is weakened, and the rock can slide off the fall arresting bar 201 to the bottom of the rock face and accumulate, so that the falling rock cannot injure people below.

[0060] This design prevents rockfalls and falls from injuring people, and it is also disassembled for easy relocation.
