Description

Technical Field

[0001] The present invention relates to the technical field of slope protection engineering, and particularly to a combined active-passive net flexible protection device. Background Art

[0002] Flexible slope protection devices mainly include active nets, passive nets, curtain nets, shed tunnels, etc. According to their respective protection principles, they can all play a good role in protecting falling rocks for their applicable slope types. The active net can effectively stabilize falling rocks in the short term. However, with the continuous weathering of slope rocks, the accumulated falling rocks in the protection net increase continuously, and the phenomenon of "bulging" will occur in the protection net, resulting in a large amount of cleaning work. Over time, it may cause the collapse of the protection net. In addition, the loss of prestress exerted by the longitudinal and transverse support ropes of the protection net on the rocks easily leads to the failure of the active net. During the process of intercepting falling rocks, the mesh of the passive net will undergo large deformation. If the passive net is set too low, the large buffer distance will inevitably damage the highway and the passive net; if the passive net is set too high, it cannot protect the falling rocks on the lower slope of the passive net. In addition, the passive net only plays a role in slowing down the rolling speed of falling rocks. Even after deceleration, the falling rocks are still likely to roll onto the highway, bringing risks to vehicle traffic on the highway. Summary of the Invention

[0003] The purpose of the present invention is to provide a combined active-passive net flexible protection device, which intercepts falling rocks through the passive net and slows down the rolling speed of the falling rocks, and fixes the decelerated falling rocks into the active net through the active net, avoiding the risk brought by the falling rocks rolling onto the highway to vehicle traffic.

[0004] To achieve the above purpose, the present invention provides a combined active-passive net flexible protection device, including: a passive protection device, an active protection net, a movable anchor rod, a baffle, a baffle support rod, and a baffle hinge seat. The passive protection device is arranged on the slope on one side of the road surface. The passive protection device includes a passive protection net. The baffle is arranged on the slope through the baffle hinge seat. One end of the baffle support rod is hinged to the side of the baffle away from the passive protection device, and the other end of the baffle support rod is locked through the movable anchor rod movably installed on the slope. One end of the active protection net is connected to the passive protection net, and the other end of the active protection net is connected to the movable anchor rod.

[0005] Optionally, the combined active-passive net flexible protection device further includes: a sliding plate, a sliding seat, and a pre-buried pipe. The sliding seat is arranged on the slope. The sliding plate is slidably arranged in the sliding seat. The pre-buried pipe is arranged in the slope on one side of the sliding seat. The baffle support rod is hinged to the sliding plate. The movable anchor rod is slidably arranged in the pre-buried pipe.

The width of the chute of the movable anchor chute is smaller than the aperture of the movable anchor hole. The diameter of the movable anchor rod near the active protection net is larger than the diameter of the movable anchor rod far from the active protection net. When the movable anchor rod slides in the direction close to the active protection net, the end of the movable anchor rod far from the active protection net slides into the movable anchor hole, and the sliding plate can be away from the baffle hinge seat through the movable anchor chute.

[0007] Optionally, a slider is arranged in the embedded pipe. The slider is connected to the movable anchor rod to prevent the movable anchor rod from slipping out of the embedded pipe.

[0008] Optionally, an elastic member is arranged on one side of the slider away from the movable anchor rod.

[0009] Optionally, a first connecting seat is arranged on one side of the sliding plate close to the baffle hinge seat, and a second connecting seat is arranged on one side of the baffle hinge seat close to the sliding plate. The first connecting seat and the second connecting seat are connected by a chain block.

[0011] Optionally, the passive protection device further includes: fixed anchor rods, upper pull anchor ropes, steel columns, steel column hinge seats and side pull anchor ropes. The steel column hinge seats are arranged on the slope, the steel columns are arranged on the steel column hinge seats, the passive protection net is arranged on the steel columns, one end of the steel column far from the steel column hinge seat is fixed by the upper pull anchor rope and the side pull anchor rope, and the upper pull anchor rope and the side pull anchor rope are fixed on the slope by the fixed anchor rods.

[0012] Optionally, energy dissipation devices are arranged on both the upper pull anchor rope and the side pull anchor rope.

[0013] Optionally, the passive protection net and the active protection net are connected by an upper fixing rope, and the distance between the upper fixing rope and the slope surface is 0.4 to 0.6 meters.

[0014] The present invention provides a combined active and passive network flexible protection device, comprising: a passive protection device, an active protection network, movable anchor rods, a baffle, a baffle support rod and a baffle hinge seat.

The following embodiments are only used to illustrate the technical solution of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0023] Figure 1 is a side view of the combined active and passive net flexible protection device provided by an embodiment of the present invention, Figure 2 is a front view of the combined active and passive net flexible protection device provided by an embodiment of the present invention, Figure 3 is a schematic diagram of the support anchor bolt provided by an embodiment of the present invention, Figure 4 is a schematic diagram of the baffle connection structure provided by an embodiment of the present invention, Figure 5 is a schematic diagram of the sliding plate structure provided by an embodiment of the present invention. See Figures 1 - 5As shown in the figure, the combined passive and active net flexible protection device includes: a passive protection device, an active protection net 8, a movable anchor rod 9, a baffle 18, a baffle support rod 19, and a baffle hinge seat 20. The passive protection device is arranged on the slope 1 on one side of the road surface 10. The passive protection device includes a passive protection net 6. The baffle 18 is arranged on the slope 1 through the baffle hinge seat 20. The baffle hinge seat 20 is anchored on the slope 1. One end of the baffle support rod 19 is hingedly connected to the side of the baffle 18 away from the passive protection device. The other end of the baffle support rod 19 is locked by the movable anchor rod 9 movably installed on the slope 1. One end of the active protection net 8 is connected to the passive protection net 6, and the other end of the active protection net 8 is connected to the movable anchor rod 9. A lower fixing rope 16 is arranged at the lower end of the active protection net 8. The active protection net 8 is connected to the upper end of the movable anchor rod 9 through the lower fixing rope 16. The falling rock 11 rolls down from the upper part of the slope 1, is buffered and decelerated by the passive protection net 6, and then rolls along the slope surface of the slope 1 at a lower speed and falls into the active protection net 8. The falling rock 11 in the active protection net 8 is supported by the baffle 18 to prevent the accumulation of the falling rock 11 from causing the collapse of the active protection net 8. When it is necessary to clean the falling rock 11, the movable anchor rod 9 is pulled out to release the baffle support rod 19, and the baffle 18 rotates to the left around the baffle hinge seat 20, and the falling rock 1 in the active protection net 8 rolls onto the road 10 and then is cleaned up.

[0024] See Figures 1 - 5 As shown in the figure, the combined passive and active net flexible protection device further includes: a slide plate 21, a slide seat 22, and a pre-embedded pipe 23. The slide seat 22 is anchored on the slope 1. The slide seat 22 includes a track for the slide plate 21 to slide. The slide plate 21 is slidably arranged in the slide seat 22. The pre-embedded pipe 23 is arranged in the slope 1 on one side of the slide seat 22. A support hinge seat 214 is arranged on the slide plate 21. The baffle support rod 19 is hingedly connected to the slide plate 21 through the support hinge seat 214. The movable anchor rod 9 is slidably arranged in the pre-embedded pipe 23. An active anchor hole 212 is arranged on the slide plate 21. The slide plate 21 is sleeved on the movable anchor rod 9 through the active anchor hole 212.

[0025] See Figures 1 - 5As shown, an active anchor chute 213 is further provided on the sliding plate 21. The active anchor chute 213 communicates with the active anchor hole 212. The width of the active anchor chute 213 is smaller than the diameter of the active anchor hole 212. The diameter of the active anchor rod 9 near one end close to the active protection net 8 is larger than the diameter of the active anchor rod 9 far from the active protection net 8. When the active anchor rod 9 is pulled upward, the end of the active anchor rod 9 far from the active protection net 8 slides into the active anchor hole 212. Under the action of gravity, the baffle 18 turns to the left, the sliding plate 21 slides to the left, and the lower end of the active anchor rod 9 can pass through the active anchor chute 213. A slider 25 is arranged in the embedded pipe 23. The slider 25 is connected to the active anchor rod 9 to prevent the active anchor rod 9 from slipping out of the embedded pipe 23. An elastic member 25 is arranged on one side of the slider 25 far from the active anchor rod 9. The elastic member 25 includes a spring.

[0026] See Figures 1 - 5 As shown, a first connection seat 211 is arranged on the sliding plate 21 near one side of the baffle hinge seat 20. A second connection seat 201 is arranged on the baffle hinge seat 20 near one side of the sliding plate 21. The first connection seat 211 and the second connection seat 201 are connected by a chain block 26. When there are more falling rocks 11 accumulated in the active protection net 8, the baffle 18 bears a greater force, and the shear force borne by the active anchor rod 9 locking the sliding plate 21 and the sliding seat 22 may be difficult to pull out. Pulling the sliding plate 21 through the chain block 26 can reduce the shear force borne by the active anchor rod 9. At the same time, when it is necessary to clean the falling rocks 11, pulling the sliding plate 21 through the chain block 26 reduces the shear force borne by the active anchor rod 9. Under the action of the elastic member 25, the active anchor rod 9 bounces upward, and then slowly released through the chain block 26, so that the falling rocks in the active protection net 8 slowly roll onto the road surface 10 for cleaning.

[0027] See Figures 1 - 5 As shown, the passive protection net 6 and the active protection net 8 are connected by an upper fixing rope 15. The distance between the upper fixing rope 15 and the slope surface of the slope 1 is 0.4 - 0.6 meters. A plurality of support anchor rods 13 are arranged on the slope between the baffle 18 and the passive protection device. The distance between adjacent two support anchor rods 13 is greater than the distance between the upper fixing rope 15 and the slope surface of the slope 1. The active protection net 8 is fixed at the top of the support anchor rod 13 through a support anchor rope 14. Both ends of the support anchor rope 14 are anchored to the slope surfaces on the left and right sides of the active protection net 8. The active protection net 8 plays a role in fixing the landing on the slope surface of the slope 1, and the baffle 18 and the support anchor rod 13 play a role in supporting the falling rocks 11.

[0028] See Figures 1 - 5As shown in the figure, the passive protection device further includes: fixed anchor bolts 2, upper pull anchor ropes 3, steel columns 5, passive protection nets 6, steel column hinge seats 7 and side pull anchor ropes 12.
