Rockfall is affected by multiple factors and is unpredictable in terms of its frequency, suddenness and randomness. It poses a great safety risk to transportation lines, mining equipment and personal safety. Therefore, the area where rockfall may occur needs to be protected.

[0046] Example

[0047] like Figures 1-12 As shown, the rockfall disaster protection pile network according to an embodiment of this application includes: ground 100, preventive protective pile network 200, main protective pile network 300, and support mechanism 400.

[0048] The protective retaining pile net 200 is installed on the flat part of the ground 100, and the main protective retaining pile net 300 is installed on the sloping side of the protective retaining pile net 200 away from the ground 100. The support mechanism 400 is hinged between the protective retaining pile net 200 and the main protective retaining pile net 300. The protective retaining pile net 200 provides the first layer of protection against rockfall disasters, directly protecting against small amounts of falling rocks. The main protective retaining pile net 300 provides reinforced protection against rockfall disasters. If the first layer of protection is damaged by continuous rockfall impacts, the main protective retaining pile net 300 can continue to provide protection. Furthermore, the bottom of the main protective retaining pile net 300 can buffer the impact force after being hit, utilizing the principle of overcoming rigidity with flexibility. This method greatly enhances the protective capability, avoiding the rigid structure of the protective piles from resisting dynamic impacts, reducing damage to the protective piles, and increasing the protective capability. The support mechanism 400 connects the preventive protective pile net 200 and the main protective pile net 300, ensuring that the two protective pile nets are in a vertical state under normal circumstances. If the preventive protective pile net 200 is impacted and tilts, the main protective pile net 300 will tilt towards the preventive protective pile net 200, dispersing the shear force brought by the rolling stones into horizontal and vertical forces, reducing the stress on the entire protective system, improving the protective capability, and increasing the safety effect. At the same time, after clearing the rolling stones, the two protective pile nets can be restored to a vertical state.

[0049] According to some embodiments of this application, such as Figures 1-3 As shown, the ground 100 includes a flat surface 110 and a slope 120, with the flat surface 110 located at the bottom of the slope 120.

[0050] The prevention pile net 200 comprises prevention piles 210 and a prevention net 220, the prevention piles 210 are fixedly installed on the flat surface 110, the prevention net 220 is fixedly installed on one side of the prevention piles 210, the prevention piles 210 are provided as at least two, the two prevention piles 210 are completely same in structure size, the prevention piles 210 are provided with first bases 211 at bottom ends, the first bases 211 are fixedly installed on the flat surface 110 by four first anchor rods 212, damage to the vegetation on the slope surface is avoided, and it is convenient for workers to install and maintain, the four first anchor rods 212 are completely same in structure size, the first bases 211 are provided with first prevention piles 213 at top ends, the first prevention piles 213 are hingedly connected with the first bases 211, so that the first prevention piles 213 can rotate, the first prevention piles 213 are provided as at least two, the two first prevention piles 213 are completely same in structure size, the first prevention piles 213 are provided in a cylindrical shape, a contact surface with the rolling stone is reduced, and the impact force can be dispersed at the same time, the first prevention piles 213 are provided with first clamps 214 at bottom end portions, the first clamps 214 are fixedly installed by double-row bolts, the double-row bolts of the first clamps 214 are penetrated through the top of a first limiting rod 215, so that the first limiting rod 215 is fixed, the bottom end of the first limiting rod 215 cooperates with the first base 211, the rotating direction of the first prevention piles 213 is limited, so that the first prevention piles 213 can only rotate to a side away from the first limiting rod 215, the mesh hole of the prevention net 220 adopts a hole diameter of an inscribed circle diameter of 150mm-300mm, so that the prevention net 220 can block the rolling stone with a diameter greater than the hole diameter.

[0051] The main prevention pile net 300 is installed on a side of the prevention pile net 200 away from the slope surface 120, and is used for reinforcing the prevention of the rolling stone disaster.

[0052] The support mechanism 400 is arranged between the prevention pile net 200 and the main prevention pile net 300, and is used for connecting the prevention pile net 200 and the main prevention pile net 300.

[0053] In the related art, the fixation of the prevention pile adopts the anchor rod to directly anchor the inside of the ground 100, and this is a rigid structure, and the rigid structure is used to resist the dynamic impact, so that the disadvantage of "double the work and half the result" exists in principle, and the prevention pile is prone to serious deformation or direct damage when subjected to overload impact.

[0054] According to some embodiments of the present application, as Figure 1 and Figures 4-9As shown, the main protection pile net 300 comprises a main protection pile 310, a main protection net 320 and a buffer 330, the main protection pile 310 is fixedly installed on the upper surface of the buffer 330, the main protection net 320 is arranged on the side of the main protection pile 310 away from the slope surface 120, so that the main protection net 320 can remove the impact force to a certain extent with the help of other components, the buffer 330 comprises a fixed plate 331, a second anchor rod 332, a vertical rod 333, a horizontal rod 334, a first spring 335, a second spring 336, an outer shell 337 and a protective shell 338, the fixed plate 331 is fixedly installed on the upper surface of the flat surface 110 through the second anchor rod 332, the vertical rod 333 is fixed on the upper surface of the fixed plate 331, the horizontal rod 334 is slidably penetrated through the bottom of the vertical rod 333, the first spring 335 is sleeved on the outer surface of the horizontal rod 334, the second spring 336 is fixedly installed on the top end of the vertical rod 333, the outer shell 337 is fixedly installed on the inner wall top end of the protective shell 338, the outer shell 337 is sleeved on the vertical rod 333 and the horizontal rod 334, so that the protective shell 338 can make linear displacement on the upper end of the fixed plate 331, so as to achieve the effect of buffering and unloading force for the main protection pile 310.

[0055] As shown in the figure, Figure 5 As shown, the main protection pile 310 comprises a second base 311, a second protection pile 312, a second clamp 313 and a second limiting rod 314, the second base 311 is bolted on the upper surface of the protective shell 338, the second protection pile 312 is hinged to the second base 311, the second clamp 313 is fixedly sleeved on the bottom of the second protection pile 312, the second clamp 313 is fixedly installed by double-row bolts, the top end of the second limiting rod 314 is sleeved on the double-row bolts of the second clamp 313, and the bottom end of the second limiting rod 314 cooperates with the upper surface of the second base 311.

[0056] It should be noted that the mesh of the main protection net 320 adopts a hole diameter of an inscribed circle diameter of 100㎜-150㎜, which can block the rolling stones that the pre-protection pile net 200 cannot block, and the main protection net 320 is fixedly installed on the main protection pile 310 by cooperating with a shackle, a supporting rope and a pressure reducing ring, so as to buffer and reduce the impact force on the main protection net 320 as much as possible by taking advantage of the soft overcomes the hard, and avoid overloading and damaging the main protection net 320.

[0057] As shown in the figure, Figures 6-9 As shown, the vertical rod 333, the horizontal rod 334, the second spring 336 and the outer shell 337 are all arranged as four, the four vertical rods 333, the horizontal rods 334, the second springs 336 and the outer shells 337 cooperate one by one, the top end of the vertical rod 333 is provided with a limiting block, the second spring 336 is fixed on the upper surface of the limiting block at the top end of the vertical rod 333, the first spring 335 is arranged at both ends of the horizontal rod 334, two first springs 335 and one horizontal rod 334 cooperate, the bottom of the outer shell 337 is provided with holes on both sides, and the both ends of the horizontal rod 334 are penetrated through the holes on both sides of the bottom of the outer shell 337.

[0058] It should be noted that the installation direction of the horizontal rod 334 is the direction pointing to the slope surface 120.

[0059] Therefore, when the rolling stone impacts the second guard pile 312, the second limiting rod 314 abuts against the second base 311, and the second guard pile 312 is limited from rotating. The second guard pile 312 is fixed on the protection shell 338, the protection shell 338 is sleeved on the upper end of the fixed plate 331 through the four housings 337, the vertical rod 333 is fixed on the fixed plate 331, the horizontal rod 334 is slidably penetrated through the vertical rod 333, the horizontal rod 334 is further penetrated through two holes in the bottom of the housing 337, and the part of the horizontal rod 334 in the housing 337 is sleeved with the first spring 335. The top end of the vertical rod 333 in the housing 337 is fixed with the second spring 336. Therefore, the impact force will make the protection shell 338 descend and displace away from the slope surface 120, and the first spring 335 and the second spring 336 buffer the impact force borne by the protection shell 338 and the second guard pile 312. When the rolling stone falls on the ground 100, the first spring 335 and the second spring 336 make the protection shell 338 and the second guard pile 312 return to the normal position, so that the main guard pile net 300 greatly improves the protection ability by using the method of softness overcoming hardness, and avoids the rigid structure of the guard pile resisting the dynamic impact, reduces the damage of the guard pile, and increases the protection ability.

[0060] In the related art, after the guard pile net is tilted by the impact of the rolling stone, the damaged equipment can only be manually maintained and replaced, and the protection ability sharply decreases during this period. Once a large number of rolling stones impact again, unpredictable danger and loss may occur.

[0061] According to some embodiments of the present application, as Figures 10-12As shown, the support mechanism 400 comprises a fixing member 410, a first connecting rod 420 and a connecting member 430. The fixing member 410 comprises a bottom plate 411, fixing rods 412 and elastic members 413. The bottom plate 411 is bolted to the upper surface of the second base 311. The bottom ends of the fixing rods 412 are fixed to the upper surface of the bottom plate 411. Two fixing rods 412 are arranged. The bottom ends of the elastic members 413 are fixed to the bottom plate 411. The elastic members 413 are arranged between the two fixing rods 412. The first connecting rod 420 is hingedly connected to the top ends of the elastic members 413. The end of the first connecting rod 420 away from the elastic members 413 is hingedly connected to the connecting member 430. The connecting member 430 comprises a second connecting rod 431, a third clamping hoop 432 and a fourth clamping hoop 433. The second connecting rod 431 is hingedly connected to the position between the two fixing rods 412. The second connecting rod 431 is hingedly connected to the first connecting rod 420 at a position below the hinged connection between the second connecting rod 431 and the fixing rods 412. The end of the second connecting rod 431 close to the first protective stake 210 is hingedly connected to the third clamping hoop 432. The end of the second connecting rod 431 close to the main protective stake 310 is hingedly connected to the fourth clamping hoop 433. The third clamping hoop 432 is slidingly sleeved on the first protective stake 213. The fourth clamping hoop 433 is slidingly sleeved on the second protective stake 312. When the second connecting rod 431 rotates around the hinged connection between the second connecting rod 431 and the fixing rods 412, the first protective stake 213 and the second protective stake 312 can slide in the two clamping hoops, so that the two protective stakes can be inclined to each other.

[0062] It should be noted that a spring is installed in the elastic member 413. The elastic force generated by the spring is slightly greater than the pressure of the equipment, so that the equipment can be restored to the vertical state when the equipment is not hit or pressed by rolling stones.

[0063] Further, the height of the second protective stake 312 is 1-1.5 times the height of the first protective stake 213. The initial position of the fourth clamping hoop 433 slidingly installed on the second protective stake 312 is higher than the initial position of the third clamping hoop 432 slidingly installed on the first protective stake 213.

[0064] When the slope 120 has more rolling stones or the impact force of the rolling stones is larger, and the first protective pile 213 is forced to incline towards the second protective pile 312, the second connecting rod 431 rotates around the hinge between the second connecting rod 431 and the fixed rod 412, the second connecting rod 431 is hinged with the third clasp 432 and the fourth clasp 433, and the third clasp 432 and the fourth clasp 433 are respectively slidably connected with the first protective pile 213 and the second protective pile 312, the bottom end of the first protective pile 213 is hinged and can only incline towards the second protective pile 312 under the limitation of the first limiting rod 215, the bottom end of the second protective pile 312 is hinged and can only incline towards the first protective pile 213 under the limitation of the second limiting rod 314, therefore, under the rotation of the second connecting rod 431, the fourth clasp 433 moves towards the top end of the second protective pile 312, at the same time, the third clasp 432 moves towards the bottom end of the first protective pile 213, and then the first protective pile 213 and the second protective pile 312 synchronously incline towards each other, at the same time, because the installation position of the first connecting rod 420 is slightly lower than the hinge between the second connecting rod 431 and the first connecting rod 420, when the end of the second connecting rod 431 close to the third clasp 432 rotates downwards, the end of the first connecting rod 420 close to the second connecting rod 431 starts to move downwards, the length of the first connecting rod 420 is fixed, and the other end of the first connecting rod 420 is hinged to the top end of the elastic member 413, therefore, a pushing force is applied to the elastic member 413, causing the elastic member 413 to contract inwardly, at this time, the first protective pile 213 and the second protective pile 312 complete the mutual inclination action, and most of the impact force of the rolling stones on the first protective pile 213 is transmitted to the second protective pile 312, the inclined second protective pile 312 converts the transmitted impact force into a downward vertical force and a horizontal force away from the slope 120, and then transmits the two forces to the protective shell 338, and the protective shell 338 and the fixed plate 331, i.e. the ground 100, further buffers the force through the first spring 335 and the second spring 336, and finally transmits the force to the ground 100. This design disperses the shearing force brought by the rolling stones into horizontal and vertical forces, reduces the stress on the entire protection system, improves the protection ability, increases the safety effect, further reduces the probability of damage to the protection system, and when the rolling stones are cleaned, the first protective pile 213 and the second protective pile 312 can be restored to the vertical position under the rebound force of the elastic member 413, reducing the maintenance workload of the staff.

[0065] Specifically, the working principle of the rockfall protection pile net is as follows: when the amount of rolling stones is small or the impact force of the rolling stones is small, the first protection pile 213 can directly block the rolling stones in cooperation with the pre-protection net 220; when the amount of rolling stones is large (continuous rolling stones) or the impact force of the rolling stones is large, the pre-protection pile net 200 is tilted towards the main protection pile net 300 under the large force, at this time, the second connecting rod 431, the third clamping hoop 432 and the fourth clamping hoop 433 are rotated at the top end of the fixed rod 412 under the force, the bottom end of the first protection pile 213 and the second protection pile 312 are hinged and can only be rotated towards each other under the action of the first limiting rod 215 and the second limiting rod 314, thereby making the first protection pile 213 and the second protection pile 312 complete the tilting action, at the same time, the first connecting rod 420 extrudes the elastic element 413 inward, the bottom end of the second protection pile 312 drives the protection shell 338 to displace on the fixed plate 331 in a direction away from the first protection pile 213, and the most impact force of the rolling stones is dispersed into downward force and force in a direction away from the first protection pile 213 through the tilted second protection pile 312, so that the impact force of the rolling stones on the protection system is buffered, dispersed and reduced as much as possible, and at the same time, the elastic force of the first spring 335, the second spring 336 and the elastic element 413 after being pressed can restore the entire protection system to the initial protection state after the rolling stones are cleaned or the pressure applied to the protection system is insufficient. This design does not need to install equipment on the slope 120, so that the vegetation on the slope 120 is protected, and the vegetation itself can also block the rolling stones to a certain extent. The protection system itself uses the method of using softness to overcome hardness, so that the protection capacity is improved, and the cooperation between the double protection further increases the service life and safety performance of the protection system, and facilitates the installation and maintenance of the staff.

[0066] It should be noted that the specific model specifications of the first anchor rod 212, the first clamping hoop 214, the pre-protection net 220, the second clamping hoop 313, the main protection net 320, the second anchor rod 332, the first spring 335, the second spring 336, the third clamping hoop 432 and the fourth clamping hoop 433 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0067] The structure and principle of the first anchor rod 212, the pre-protection net 220, the main protection net 320 and the second anchor rod 332 are clear to those skilled in the art, and will not be described in detail here.
