Structures and methods for preventing collapse of roadbed rock slopes Technical Field
[0001] This invention relates to the field of roadbed slope collapse prevention technology, specifically to roadbed rock slope collapse prevention structures and methods. Background Technology
[0002] Rock subgrade refers to a structure that uses crushed rock as the base layer of a road surface. In mountain roads or other special areas with loose soil, rock subgrade is often required as the base layer of a road surface. During the use of rock subgrade, a collapse-resistant structure is often needed to support the outer surface of the rock subgrade to prevent material from falling off or collapsing. Technical issues
[0003] However, existing roadbed rock slope anti-collapse structures have some shortcomings, such as:
[0004] A slope protection structure, application number CN202322285455.X, involves excavating and pouring piles at the top of the slope. Several pillars are connected to crossbeams, waist beams, and foot beams to form several triangular grids, effectively preventing slope collapse. This structure can support high and steep roadbed slopes without occupying much space, and it also provides good slope stability, preventing slope collapse. However, in actual use, the structure has difficulty supporting slope protection panels and other mechanisms, which may lead to insufficient support when protecting the surface of rock roadbed slopes, thus reducing the protection efficiency of the structure.
[0005] Therefore, we proposed a structure and method for preventing the collapse of roadbed rock slopes in order to solve the problems mentioned above. Technical solutions
[0006] The purpose of this invention is to provide a structure and method for preventing the collapse of roadbed rock slopes, in order to solve the problem mentioned in the background art that most roadbed rock slope prevention structures on the market are difficult to support the slope protection plate and other mechanisms, which may lead to insufficient support when the equipment is used to protect and support the slope surface of the rock roadbed, thereby reducing the protection efficiency of the equipment.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a roadbed rock slope anti-collapse structure, including a device body and a slope protection plate set on the top of the device body; a concrete pouring slab is provided on the top of the device body, and a support mechanism is provided on the top of the device body, and the support mechanism is slidably connected to the device body, and the top left end of the device body is rotatably connected to the slope protection plate;
[0008] The slope protection panel has a fixed frame inside and a fixed shaft inside. The fixed frame is fixedly connected to the outside of the slope protection panel. The fixed frame is fixedly connected to the fixed shaft. The support mechanism can drive the slope protection panel to adjust its angle and position during operation.
[0009] By supporting the slope protection panels with a support mechanism, the slope protection panels can be protected on the slope surface of rock roadbeds. This increases the support force of the equipment and makes it easier to adjust the angle of the slope protection panels, thus increasing the adjustability of the equipment.
[0010] As a preferred technical solution of the present invention, the main body of the device is provided with a control mechanism, and the control mechanism includes a torsion shaft, which is fixedly connected to a first sprocket. A chain is engaged on the outer side of the first sprocket, and a second sprocket is engaged at the rear end of the chain.
[0011] The above technical solution makes it easier for the control mechanism to adjust the position of the support mechanism, thereby increasing the adjustability of the equipment.
[0012] As a preferred technical solution of the present invention, the first sprocket and the second sprocket are connected to the support mechanism, and the support mechanism includes two sets of reciprocating screws. The first sprocket and the second sprocket are respectively fixedly connected to a set of reciprocating screws. A screw sleeve is provided on the outside of the reciprocating screw, and an embedded post is connected to the left end of the screw sleeve. The embedded post is threadedly slidably connected to the reciprocating screw.
[0013] The top of the lead screw sleeve is provided with a first rotating shaft, and the top of the first rotating shaft is provided with a first support rod, and the top of the first support rod is provided with a rotating rod. The first support rod is rotatably connected to the left and right sides of the slope protection plate through the rotating rod.
[0014] The above technical solution makes it easier to adjust the angle of the slope protection plate with the first support rod, thereby increasing the convenience of the equipment when adjusting the angle.
[0015] As a preferred technical solution of the present invention, the top of the slope protection plate is provided with an upper connecting plate, and the front end of the fixing frame is provided with a first fixing pile head, and the front side of the upper connecting plate is provided with a second fixing pile head. The right end of the slope protection plate is provided with a diversion channel, and the bottom of the diversion channel is connected to a drainage outlet.
[0016] The fixed frame is equipped with a sliding sleeve, and the sliding sleeve is equipped with a prestressed pile. The prestressed pile is slidably connected to the inside of the sliding sleeve. The slope protection plate is equipped with a support net on the front side, and the support net is a wire mesh with an iron frame structure.
[0017] The above technical solution enables the slope protection slab to be fixed to the interior of the rock roadbed through prestressed piles when connected to the interior of the rock roadbed, thereby fixing the slope protection slab to the surface of the rock roadbed and making the slope protection slab more stable when fixed to the slope surface of the rock roadbed.
[0018] As a preferred technical solution of the present invention, the slope protection plate is fixedly connected to the fixed shaft, and the rear end of the fixed shaft is provided with a second support rod, and the bottom of the second support rod is provided with a second rotating shaft. The bottom of the second rotating shaft is provided with a slider, and the slider is provided with a sliding rod inside, and the sliding rod is fixedly connected to the inside of the concrete pouring slab.
[0019] By adopting the above technical solution, the second support rod and the second rotating shaft can better support the slope protection plate and the fixed shaft and other mechanisms when the device supports the inside of the second support rod, thereby increasing the support performance of the device.
[0020] As a preferred embodiment of the present invention, a fixing plate is connected to the bottom of the concrete pouring slab, and a fixing seat is provided inside the concrete pouring slab, and the concrete pouring slab is fixedly connected to the fixing plate through the fixing seat.
[0021] The above technical solution enables the fixing plate to fix the concrete pouring slab, thereby increasing the stability of the equipment during installation.
[0022] As a preferred technical solution of the present invention, the bottom of the fixing base is provided with a first foundation pile, and the bottom of the first foundation pile is fixedly connected with a first pile head, and the front end of the device body is provided with a connecting frame, the bottom of the connecting frame is provided with a second foundation pile, and the bottom of the second foundation pile is fixedly connected with a second pile head.
[0023] The above technical solution enables a more stable connection between the main body of the device and the concrete slab, thereby increasing the stability of the equipment during installation.
[0024] As a preferred technical solution of the present invention, the method for preventing collapse of roadbed rock slopes includes the following steps:
[0025] Step 1: Fix the main body of the device to the concrete pouring slab, and then connect it to the first foundation pile through the fixing seat. The front end of the main body of the device is connected to the second foundation pile through the connecting frame, so that the main body of the device and the concrete pouring slab are fixed to the soil base through the first foundation pile and the second foundation pile.
[0026] Step 2: Adjust the torsion shaft so that it drives the first sprocket to rotate, which in turn drives the second sprocket to rotate via the chain. This allows both sets of reciprocating screws to rotate simultaneously, causing the reciprocating screws to slide along the screw sleeve, which in turn moves the embedded pile, allowing it to insert into the road base layer and complete the first fixing. At this point, the slope protection board will also be in contact with the surface of the road base layer.
[0027] Step 3: After the slope protection board is attached to the road base surface, the first fixing pile head will be inserted into the road base surface, and the upper connecting plate on the top of the slope protection board will also be attached to the top of the road base, so that the second fixing pile head on the front side of the upper connecting plate is inserted into the road base surface. Then, the prestressed pile passes through the sliding sleeve and is inserted into the road base, thereby fixing the slope protection board and completing the second fixing.
[0028] Step 4: After the slope protection board is attached and fixed to the road base surface, the slide block will move to the designated position under the action of the slide rod because the slope protection board is connected to the slide block through the second support rod. Then, concrete is poured inside the concrete pouring board, so that the concrete pouring board and the outer concrete structure become one. At the same time, the concrete on the inner side of the concrete pouring board also fixes the position of the slide block, so that the slide block and the second support rod support the middle of the slope protection board.
[0029] As a preferred technical solution of the present invention, when the slope protection board is attached to the surface of the road base layer, the moisture on the surface of the road base layer may be squeezed out, thereby allowing the water to flow through the guide channel, so that the moisture on the surface of the road base layer is transferred to the drainage outlet for drainage through the guide channel.
[0030] The above technical solution enables water inside the rock subgrade to be discharged from the drainage outlet under the guidance of the diversion channel, thereby carrying out organized drainage and increasing the convenience of the equipment during drainage.
[0031] As a preferred technical solution of the present invention, after the slope protection board is attached to the road base surface, the support net set on the front side of the slope protection board will intercept the gravel on the road base surface, so as to prevent the gravel from falling continuously and affecting the use of the road base.
[0032] The above technical solution enables the support net to fix and support the crushed stone inside the rock roadbed, thereby preventing the crushed stone inside the rock roadbed from falling and increasing the stability of the equipment when supporting the rock roadbed. Beneficial effects
[0033] Compared with the prior art, the beneficial effects of the present invention are: by supporting the slope protection plate through the support mechanism, the slope protection plate can be supported by the support mechanism when protecting the slope surface of the rock roadbed, thereby increasing the support force of the device and making it more convenient to adjust the angle of the slope protection plate, thereby increasing the adjustability of the device.
[0034] Furthermore, by setting up the second support rod and the second rotating shaft, the device can better support the slope protection plate and fixed shaft and other mechanisms when supporting the inside of the second support rod, thereby increasing the support performance of the device.
[0035] Furthermore, by setting up a support net, the support net can fix and support the crushed stone inside the rock roadbed, thereby preventing the crushed stone inside the rock roadbed from falling off and increasing the stability of the equipment when supporting the rock roadbed.

[0051] The first sprocket 4 and the second sprocket 6 are connected to the support mechanism, and the support mechanism includes two sets of reciprocating screws 7. The first sprocket 4 and the second sprocket 6 are respectively fixedly connected to a set of reciprocating screws 7. A screw sleeve 8 is provided on the outside of the reciprocating screw 7, and an embedded post 9 is connected to the left end of the screw sleeve 8. The embedded post 9 is threadedly slidably connected to the reciprocating screw 7.
[0052] The top of the screw sleeve 8 is provided with a first rotating shaft 10, and the top of the first rotating shaft 10 is provided with a first support rod 11, and the top of the first support rod 11 is provided with a rotating rod 12. The first support rod 11 is rotatably connected to the left and right sides of the slope protection plate 13 through the rotating rod 12.
[0053] When the first support rod 11 is moved by the first rotating shaft 10, the top of the first support rod 11 can drive the slope protection plate 13 to adjust its angle through the rotating rod 12, which makes it more convenient to adjust the angle of the slope protection plate 13.
[0054] The top of the slope protection plate 13 is provided with an upper connecting plate 17, and the front end of the fixing frame 14 is provided with a first fixing pile head 16, and the front side of the upper connecting plate 17 is provided with a second fixing pile head 18. The right end of the slope protection plate 13 is provided with a diversion channel 19, and the bottom of the diversion channel 19 is connected to a drainage outlet 20.
[0055] The fixed frame 14 is provided with a sliding sleeve 21, and the sliding sleeve 21 is provided with a prestressed pile 22, and the prestressed pile 22 is slidably connected to the sliding sleeve 21. The slope protection plate 13 is provided with a support net 34 on the front side, and the support net 34 is a wire mesh with an iron frame structure.
[0056] The slope protection plate 13 is fixedly connected to the fixed shaft 15, and the rear end of the fixed shaft 15 is provided with a second support rod 23, and the bottom of the second support rod 23 is provided with a second rotating shaft 24. The bottom of the second rotating shaft 24 is provided with a slider 25, and the slider 25 is provided with a sliding rod 26 inside, and the sliding rod 26 is fixedly connected to the inside of the concrete pouring plate 2.
[0057] A fixing plate 33 is connected to the bottom of the concrete pouring slab 2, and a fixing seat 27 is provided inside the concrete pouring slab 2. The concrete pouring slab 2 is fixedly connected to the fixing plate 33 through the fixing seat 27.

A connecting frame 30 is provided at the front end of the main body 1. A second foundation pile 31 is provided at the bottom of the connecting frame 30, and a second pile head 32 is fixedly connected to the bottom of the second foundation pile 31.
[0058] The method for preventing collapse of roadbed rock slopes includes the following steps:
[0059] Step 1: Fix the main body 1 of the device to the concrete pouring slab 2, and then connect it to the first foundation pile 28 through the fixing seat 27. The front end of the main body 1 of the device is connected to the second foundation pile 31 through the connecting frame 30, so that the main body 1 of the device and the concrete pouring slab 2 are fixed to the soil base through the first foundation pile 28 and the second foundation pile 31.
[0060] Step 2: Adjust the torsion shaft 3 so that the torsion shaft 3 drives the first sprocket 4 to rotate, thereby causing the first sprocket 4 to drive the second sprocket 6 to rotate through the chain 5. This allows the two sets of reciprocating screws 7 to rotate simultaneously, thereby causing the reciprocating screws 7 to drive the screw sleeve 8 to slide, thereby causing the screw sleeve 8 to drive the embedded pile 9 to move, so that the embedded pile 9 is inserted into the road base layer, completing the first fixing. At this time, the slope protection plate 13 will also be in contact with the surface of the road base layer.
[0061] Step 3: After the slope protection board 13 is attached to the road base surface, the first fixing pile head 16 will be inserted into the road base surface, and the upper connecting plate 17 on the top of the slope protection board 13 will also be attached to the top of the road base, so that the second fixing pile head 18 on the front side of the upper connecting plate 17 is inserted into the road base surface. Then, the prestressed pile 22 passes through the sliding sleeve 21 and is inserted into the road base, thereby fixing the slope protection board 13 and completing the second fixing.
[0062] Step 4: After the slope protection board 13 is attached and fixed to the road base surface, since the slope protection board 13 is connected to the slider 25 through the second support rod 23, the slider 25 will move to the designated position under the action of the sliding rod 26. Then, concrete is poured inside the concrete pouring slab 2, so that the concrete pouring slab 2 and the outer concrete structure form an integral whole. At the same time, the concrete on the inner side of the concrete pouring slab 2 also fixes the position of the slider 25, so that the slider 25 and the second support rod 23 support the middle part of the slope protection board 13.
[0063] When the slope protection board 13 is attached to the road base surface, the water on the road base surface may be squeezed out, which causes the diversion channel 19 to guide the water flow, so that the water on the road base surface is transferred to the drainage outlet 20 for drainage through the diversion channel 19.
[0064] After the slope protection board 13 is attached to the road base surface, the support net 34 set on the front side of the slope protection board 13 will intercept the gravel on the road base surface, preventing the gravel from falling continuously and affecting the use of the road base.
[0065] When the slope protection plate 13 is too long, it can be fixed by adding a fixing shaft 15 inside the slope protection plate 13. Then, a second support rod 23 and a second rotating shaft 24 are added to the rear side of the fixing shaft 15 to support the fixing shaft 15, so that the equipment can be more secure when supporting and protecting the slope of the rock roadbed.
[0066] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
