DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown, an embodiment of the present invention provides a slope protection device for rock collapse, comprising a concrete frame 1, and further comprising: A bottom base 8 is fixed to the bottom end of the concrete frame 1; The drainage structure 7 is arranged at one side of the bottom end of the bottom base 8 and is used to drain the accumulated water at the bottom of the rock soil and the slope; A first water retaining plate 5 is arranged at the top of one side of the drainage structure 7; A cleaning structure 6 is arranged inside the drainage structure 7 and is used to clean the inside of the drainage structure 7; The buffer structure 4 is arranged on one side of the concrete frame 1 and is used to intercept and buffer the falling rocks and vegetation; The greening assembly is arranged inside the concrete frame 1 , and anchor rods are inserted inside the concrete frame 1 . A second water retaining plate 11 is fixed to the top of the concrete frame 1 .

[0020] The working principle and beneficial effects of the above technical solution are as follows: before construction, the slope needs to be thoroughly cleaned, all loose pumice and rock debris removed, and then the cavities and grooves on the slope surface are filled and repaired with mortared stone slabs to ensure that the slope surface is flat. Subsequently, according to the design specifications and soil layer characteristics, a groove is preset on the surface of the slope, and a hole is drilled at a designated position. Then, the rod body 12 is inserted into the drilled hole, and cement mortar is poured into the hole through the injection groove 15, so as to firmly anchor the rod body 12 in the rock layer. At the same time, the inverted teeth 16 are used to enhance the friction between the rod body 12 and the cement mortar to ensure stability, and a frame beam template is constructed in the groove area, and then steel bars and mounting seats 3 are laid on the template, and the steel bars are connected to the anchor rods. After that, concrete is poured into the template to initially form the structure of the concrete frame 1. At the same time, concrete is poured at the top and bottom of the slope to construct the second water retaining plate 11, the first water retaining plate 5 and the drainage channel 701, in order to prevent the surface water flow from directly scouring the joint between the concrete frame 1 and the slope. The culture soil 9 is loaded in advance through the degradable paper box 13, and the grass seeds are planted therein. Subsequently, the degradable paper box 13 containing the seeds is placed in the reserved space inside the concrete frame 1, and the grid 10 is fastened to the mounting seat 3 by bolts to fix the position of the degradable paper box 13 to prevent it from falling off. In addition, the grid 10 can also prevent the large rocks in the space from falling. As the plant roots in the culture soil 9 grow, they will be interwoven into a mesh structure in the soil, effectively improving the cohesiveness and cohesion of the soil and enhancing the stability of the soil. When constructing the drainage channel 701, it is connected to the road drainage system to ensure that the water at the bottom of the slope can be directly discharged. The buffer structure 4 acts as a barrier to intercept small rocks, soil and vegetation, reduce their impact on the drainage channel 701, and effectively prevent large-volume falling objects from entering the drainage channel 701. If siltation occurs in the drainage channel 701, it can be cleaned by the cleaning structure 6 to keep it unobstructed, and the siltation can be centrally processed to facilitate road maintenance.

[0021] like Figure 5As shown, in one embodiment: the cleaning structure 6 includes a first support 604 installed inside the drainage structure 7, a transmission shaft 601 rotatably connected to the inside of the first support 604, a spiral impeller 603 fixed to the outside of both sides of the transmission shaft 601, a first sprocket 602 fixed at the middle position of the transmission shaft 601, a chain 610 meshed on the outside of the first sprocket 602, a scraper 608 fixed on the outside of the chain 610, and a transmission assembly arranged inside the top of the chain 610.

[0022] The working principle and beneficial effects of the above technical solution are as follows: the chain 610 and the scraper 608 are driven to move by the driving motor 606 through the second sprocket 607, and then the scraper 608 scrapes the silt inside the drain 701 to move it along the slope of the drain 701 and leaves the inside of the drain 701. At the same time, the chain 610 drives the transmission shaft 601 to rotate through the first sprocket 602, so that the transmission shaft 601 drives the spiral impeller 603 to rotate, so that the spiral spiral impeller 603 pushes the silt to move, and the left and right sets of spiral impellers 603 are used to transport the silt in other areas of the drain 701 to the bottom of the scraper 608, thereby increasing the cleaning range of the device, and supporting and fixing the transmission shaft 601 through the first support 604.

[0023] like Figure 5 As shown, in one embodiment: the transmission assembly includes a second support 609 fixed to one side of the top end of the cleaning structure 6, a second sprocket 607 rotatably connected to the inside of the second support 609 and meshingly connected to the chain 610, a driving motor 606 installed on one side of the second support 609 and with the rotating end connected to the second sprocket 607, and a waterproof shell 605 mounted on the outside of the driving motor 606 and connected to the second support 609.

[0024] The working principle and beneficial effects of the above technical solution are as follows: the road maintenance personnel start the driving motor 606 to drive the second sprocket 607 to rotate, so that the second sprocket 607 drives the chain 610 and the scraper 608 to move.

[0025] like Figure 5 As shown, in one embodiment: the spiral impellers 603 are symmetrically distributed on both sides of the transmission shaft 601, and the directions of the spiral impellers 603 on both sides of the transmission shaft 601 are opposite, and several groups of scrapers 608 are arranged on the outside of the chain 610, and the several groups of scrapers 608 are evenly spaced on the outside of the chain 610.

[0026] The working principle and beneficial effects of the above technical solution are as follows: since the directions of the spiral impellers 603 on the left and right sides of the transmission shaft 601 are opposite, when the transmission shaft 601 rotates, the spiral impellers 603 push the silt to move to the middle position of the transmission shaft 601.

[0027] like Figure 1 and Figure 7 As shown, in one embodiment: the drainage structure 7 includes a drainage channel 701 fixed at the bottom end of the cleaning structure 6 and connected to the first water baffle 5, a guide plate 702 installed at the bottom end of the drainage channel 701, a drainage pipe 703 inserted inside one side of the drainage channel 701, a stainless steel filter screen 706 fixed to the outer wall of the drainage pipe 703, a baffle 704 fixed to the outside of the drainage pipe 703 and a conical head 705 fixed to the top of the drainage pipe 703.

[0028] The working principle and beneficial effects of the above technical solution are as follows: the accumulated water at the bottom of the slope is guided and discharged through the drainage channel 701, so that the bottom of the device can be easily immersed in the accumulated water. At the same time, the guide plate 702 is used to guide the water flow on the surface of the slope, reduce the impact of the water flow on the drainage channel 701, and extend the service life of the drainage channel 701. The drainage pipe 703 is inserted deep into the rock and soil, so that excess water in the deep rock and soil can pass through the stainless steel filter 706 into the interior of the drainage pipe 703, thereby discharging the water in the deep rock and soil of the slope and reducing its water content.

[0029] like Figure 1 and Figure 7 As shown, in one embodiment: the baffle 704 is in a spiral structure, the diameter of the baffle 704 is opposite to the diameter of the conical head 705, and the baffle 704 and the drain pipe 703 are welded into an integrated structure.

[0030] The working principle and beneficial effects of the above technical solution are: at the same time, the baffle 704 supports the rocks and soil outside the drain pipe 703, so that a certain degree of cavity is formed on the outside of the stainless steel filter 706, making the stainless steel filter 706 not easy to be blocked, and facilitating the introduction of accumulated water into the interior of the drain pipe 703.

[0031] like Figure 1 and Fig. 9 As shown, in one embodiment: the buffer structure 4 includes a guide plate 402 installed on one side of the concrete frame 1, a connecting seat 407 arranged at the bottom end of the guide plate 402 and connected to the concrete frame 1, a connecting frame 408 installed on one side of the connecting seat 407, a telescopic spring 403 fixed at the top of the connecting frame 408, a connecting frame 408 installed at the top of the telescopic spring 403, a guide rod 404 fixed at the bottom end of the connecting frame 408 and slidably connected to the support frame 406, an outer frame 401 fixed at the top of the connecting frame 408, and a wire mesh 405 installed inside the outer frame 401.

[0032] The working principle and beneficial effects of the above technical solution are as follows: the fallen objects are guided by the guide plate 402, so that the fallen objects move toward the outer frame 401 and impact the wire mesh 405. At the same time, the wire mesh 405 buffers the impact and reduces the impact on the outer frame 401. At the same time, the outer frame 401 can push the telescopic spring 403 to telescopically deform through the connecting frame 408 to further buffer the impact, greatly reducing the damage to the wire mesh 405 caused by the fallen objects. After buffering, small fallen objects slide down the slope of the wire mesh 405 and pass through the gap between the outer frame 401 and the concrete frame 1 and fall into the interior of the drainage ditch 701. Large fallen objects are blocked by the wire mesh 405 and accumulate on the surface of the wire mesh 405, requiring staff to clean up to restore the use of the buffer structure 4.

[0033] like Figure 1 and Fig. 9 As shown, in one embodiment: the guide rod 404 passes through the support frame 406 and is connected to the telescopic spring 403 and the connecting frame 408, and the connecting seat 407 is installed on one side of the concrete frame 1 through expansion screws.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the guide rod 404 slides inside the support frame 406 to guide the movement of the outer frame 401 and limit the movement path of the outer frame 401 .

[0035] like Figure 6 and Figure 8 As shown, in one embodiment: the greening component includes a mounting base 3 fixed on the inner wall of the concrete frame 1, a grid 10 detachably mounted on the top of the mounting base 3, a degradable paper box 13 arranged inside the concrete frame 1, a culture soil 9 arranged inside the degradable paper box 13, and a through hole 14 opened at the bottom of the degradable paper box 13, and the anchor rod includes an anchor pier 2 fixed on one side of the concrete frame 1, a rod body 12 inserted into the anchor pier 2, an injection groove 15 opened in the rod body 12, and a reverse tooth 16 fixed on the outside of the rod body 12.

[0036] Specifically, the slope protection device and protection method for rock collapse are used as follows: before construction, the slope needs to be thoroughly cleaned, all loose pumice and rock debris are removed, and then the cavities and grooves on the slope surface are filled and repaired with mortared stone slabs to ensure that the slope surface is flat. Subsequently, according to the design specifications and soil layer characteristics, a groove is preset on the slope surface, and a hole is drilled at a designated position. Then, the rod body 12 is inserted into the drilled hole, and cement mortar is poured into the hole through the injection groove 15, so as to firmly anchor the rod body 12 in the rock layer. At the same time, the inverted teeth 16 are used to enhance the friction between the rod body 12 and the cement mortar to ensure stability, and a frame beam template is constructed in the groove area, and then steel bars and mounting seats 3 are laid on the template, and the steel bars are connected to the anchor rods. After that, concrete is poured into the template to initially form the structure of the concrete frame 1. At the same time, concrete is poured at the top and bottom of the slope to construct the second water retaining plate 11, the first water retaining plate 5 and the drainage channel 701, in order to prevent the surface water flow from directly scouring the joint between the concrete frame 1 and the slope. The culture soil 9 is loaded in advance through the degradable paper box 13, and the grass seeds are planted therein. Subsequently, the degradable paper box 13 containing the seeds is placed in the reserved space inside the concrete frame 1, and the grid 10 is fastened to the mounting seat 3 by bolts to fix the position of the degradable paper box 13 to prevent it from falling off. In addition, the grid 10 can also prevent the large rocks in the space from falling. As the plant roots in the culture soil 9 grow, they will be interwoven into a mesh structure in the soil, effectively improving the cohesiveness and cohesion of the soil and enhancing the stability of the soil. When constructing the drainage channel 701, it is connected to the road drainage system to ensure that the water at the bottom of the slope can be directly discharged. The buffer structure 4 acts as a barrier to intercept small rocks, soil blocks and vegetation, reduce their impact on the drainage channel 701, and effectively prevent large-volume falling objects from entering the drainage channel 701. If siltation occurs in the drainage channel 701, it can be cleaned by the cleaning structure 6 to keep it unobstructed, and the siltation can be centrally processed to facilitate road maintenance; When sediment is generated inside the drainage channel 701, the road maintenance personnel start the driving motor 606 to drive the second sprocket 607 to rotate, so that the second sprocket 607 drives the chain 610 and the scraper 608 to move, and then the scraper 608 scrapes the sediment inside the drainage channel 701 to move it along the slope of the drainage channel 701. At the same time, the chain 610 drives the transmission shaft 601 to rotate through the first sprocket 602, so that the transmission shaft 601 drives the spiral impeller 603 to rotate, so that the spiral spiral impeller 603 pushes the sediment to move, and the left and right sets of spiral impellers 603 are used to transport the sediment in other areas of the drainage channel 701 to the bottom of the scraper 608, so as to increase the cleaning range of the device, and the transmission shaft 601 is supported and fixed by the first support 604: The accumulated water at the bottom of the slope is guided and discharged through the drainage channel 701, so that the bottom of the device is easy to be immersed in the accumulated water. At the same time, the guide plate 702 is used to guide the water flow on the surface of the slope, reduce the impact of the water flow on the drainage channel 701, and extend the service life of the drainage channel 701. The drainage pipe 703 is inserted into the deep rock and soil, so that the excess water in the deep rock and soil can pass through the stainless steel filter 706 into the interior of the drainage pipe 703, and the water in the deep rock and soil of the slope is discharged to reduce its water content. At the same time, the baffle 704 supports the rock and soil outside the drainage pipe 703, so that a certain degree of cavity is formed on the outside of the stainless steel filter 706, so that the stainless steel filter 706 is not easy to be blocked, and it is convenient to guide the accumulated water into the interior of the drainage pipe 703; When objects fall on the slope, the guide plate 402 guides the objects so that they move toward the outer frame 401 and impact the wire mesh 405. At the same time, the wire mesh 405 buffers the impact and reduces the impact on the outer frame 401. At the same time, the outer frame 401 can push the telescopic spring 403 to expand and contract through the connecting frame 408 to further buffer the impact, greatly reducing the damage to the wire mesh 405 caused by the objects. After buffering, small objects slide down along the slope of the wire mesh 405 and pass through the gap between the outer frame 401 and the concrete frame 1 and fall into the interior of the drainage ditch 701. Large objects are blocked by the wire mesh 405 and accumulate on the surface of the wire mesh 405, requiring staff to clean them up to restore the use of the buffer structure 4.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
