Description

Technical Field

[0001] This invention relates to the field of slope protection structure technology, specifically to a safety protection device and installation method for the construction of steep slope masonry rubble slope protection. Background Technology

[0002] Slope protection refers to the various paving and planting works done on slope surfaces to prevent erosion. Based on their function, slope protection can be broadly divided into two types: The first type is slope protection works that only resist weathering and erosion. These works do not bear lateral earth pressure, such as shotcrete slope protection, grid-framed vegetation slope protection, and vegetation slope protection. They are only suitable for gentle, stable slopes without the risk of sliding. The second type is retaining slope protection that provides resistance to sliding. These can be roughly divided into: (a) rigid self-weight retaining walls (such as masonry retaining walls, gravity retaining walls, wall-mounted retaining walls, cantilevered retaining walls, and buttress retaining walls); (b) flexible self-weight retaining walls (such as snake cage retaining walls, frame retaining walls, and reinforced retaining walls); and (c) anchored retaining walls (such as anchored grid beam retaining walls and anchored pile retaining walls).

[0003] For example, CN219315773U discloses a slope protection device. The slope protection device consists of a horizontal section and an inclined section. The device includes a covering layer installed on the inclined section to prevent the inclined layer from collapsing and a railing assembly installed on the horizontal section to protect personnel. The covering layer is formed by splicing multiple covering units. Each covering unit includes a rectangular frame, a barrier net installed inside the rectangular frame, and positioning posts fixedly connected to the four corners at the bottom of the rectangular frame. The upper surface of the rectangular frame has first threaded holes at the four corners. The rectangular frame is provided with a cover plate for covering the barrier net. The four corners of the cover plate are integrally formed with fixing rings. The cover plate is fixed by fastening bolts and fixing rings. It can provide stable protection for the slope and has the advantages of low cost, easy installation, and short construction period.

[0004] The aforementioned patent also has the following drawbacks: Traditional slope protection devices only use the aforementioned covering units to be installed in sections on the surface of the slope, installing one section of the slope at a time. Since the slope surface is not flat, it is not possible to protect all areas at once. Moreover, after installation, it is difficult to ensure that the slabs in other areas are flat. Due to the instability of adverse geological conditions, major geological disasters such as surface landslides and mudflows may occur, especially on steep slopes where the impact force of landslides is greater. Simply setting up simple covering units on the surface of the slope is not enough to stabilize steep slopes, resulting in insufficient protection and poor safety.

[0005] Therefore, we propose a safety protection device and installation method for the construction of steep slope masonry rubble revetment, in order to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a safety protection device and installation method for the construction of grouted rubble masonry slope protection, in order to solve the problems mentioned in the background art, which are that it is difficult to stabilize the slope of the ground by setting simple covering units on the surface of the slope protection, resulting in insufficient protection and poor safety.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a safety protection device for the construction of steep slope masonry rubble slope protection, comprising a slope protection structure and an outer shell disposed on one side of the slope protection structure;

[0008] Also includes:

[0009] A reinforcement mechanism is provided on one side of the outer shell. The reinforcement mechanism includes a connecting rod structure provided on one side of the outer shell and fixed blocks rotatably mounted at the upper and lower ends of the connecting rod structure.

[0010] The linkage structure includes a first linkage rotatably mounted on one side of the outer casing and a second linkage rotatably mounted on one side of the outer casing, wherein the first linkage and the second linkage are rotatably connected.

[0011] The two upper fixed blocks are each fixedly equipped with a first sliding rod, and the lower ends of the two lower fixed blocks are each rotatably equipped with a second sliding rod. The middle of the two second sliding rods are threadedly connected to a threaded rod, and a first pressing sleeve is rotatably connected to the outer wall of the first sliding rod.

[0012] Preferably, the outer shell is rotatably mounted with movable wheels at both ends, a connecting block is fixedly mounted on one side of the outer shell, one end of the threaded rod is rotatably connected to the connecting block, and an inner baffle is fixedly mounted inside the outer shell, with a sliding groove provided on the inner baffle.

[0013] Preferably, a first I-shaped wheel is fixedly installed at one end of the first sliding rod, a first inner groove is opened inside the first sliding rod, and a first inner rod is connected between two adjacent first sliding rods. The two ends of the first inner rod are slidably installed in the first inner groove, and the first inner rod is slidably installed in two first pressing sleeves.

[0014] Preferably, a pressing mechanism is connected between the two first I-shaped wheels. The pressing mechanism includes a second pressing sleeve rotatably mounted on the end of the first pressing sleeve away from the first sliding rod, and a second inner rod is slidably mounted between two adjacent second pressing sleeves.

[0015] Preferably, a second I-shaped wheel is rotatably mounted on one end of the second sliding rod, and a third sliding rod is connected to the second sliding rod through a linkage structure. One end of the third sliding rod is connected to an unwinding mechanism, and a track is wound on the unwinding mechanism. One end of the track is also attached to the second I-shaped wheel and the first I-shaped wheel.

[0016] Preferably, a winding mechanism is provided on one side of the second I-shaped wheel. The winding mechanism includes a central rod fixedly installed between the two connecting blocks and a winding roller fixedly installed on the central rod. One end of the track is wound around the winding roller, and a connecting sleeve is provided at one end of the winding roller. A spiral spring is installed between the connecting sleeve and the central rod.

[0017] Preferably, both the first connecting rod and the second connecting rod are provided with sliding grooves, and sliders are slidably installed on the sliding grooves. A stabilizing rod is fixedly installed on both sliders.

[0018] Preferably, the track has multiple through holes at equal intervals, and the other end of the track has a clearance groove that communicates with the through holes. The diameter of the clearance groove is larger than the diameter of the through holes.

[0019] Preferably, the track is further provided with a gripping mechanism, which includes a sliding block slidably mounted on the through hole, a conical block fixedly mounted on one end of the sliding block, and a wedge block fixedly mounted on the end of the sliding block away from the conical block. An elastic element is connected between the wedge block and the wall of the clearance groove.

[0020] This invention also discloses an installation method for a safety protection device used in the construction of steep slope masonry rubble masonry slope protection, comprising the following steps:

[0021] S1: First, move the outer shell to one side of the slope protection, and then place the connecting block against one side of the slope protection;

[0022] S2: The track is respectively fitted onto the unwinding mechanism, the second I-shaped wheel, the first I-shaped wheel, and the winding mechanism;

[0023] S3: Turn on the motor, the threaded rod rotates, the two fixed blocks on the left and right move closer to each other, the first and second connecting rods after folding rotate, and the height gradually increases. During this process, the first and second pressing sleeves also roll upward continuously to roll the slope.

[0024] S4: The tracks unfold, and the cone blocks penetrate further into the ground, further reinforcing the slope;

[0025] S5: The drive motor reverses, the first and second connecting rods reset and fold, the tracks reset, and the outer shell is removed.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. When using this device, first place one side of the outer casing against the slope, turn on the motor, and the threaded rod will rotate. The two fixed blocks on the left and right will move closer to each other, and the folded first and second connecting rods will rotate, gradually increasing in height. During this process, the first pressing sleeve will also roll upward continuously, compacting the loose soil on the slope surface, improving the looseness and unevenness of the slope surface, and reinforcing the slope surface. This ensures that the slope surface is compact and has high flatness. Combined with the reinforcement of the slope surface by masonry, it further increases the protection effect of the slope surface. Moreover, the device is distributed in a point-like manner on the slope surface by the first pressing sleeve, which makes it easy to avoid uneven areas of the slope surface. It has strong adaptability and greatly reduces the risk of surface landslides and mudflow erosion, resulting in high safety performance.

[0028] 2. Through the cooperation between the first sliding rod, the first I-shaped wheel, the first inner groove, the first inner rod, and the first pressing sleeve, during the sliding process of the first connecting rod and the second connecting rod, the first inner rod adaptably slides in the first inner groove. At the same time, the two sliders of the stabilizing rod also slide about the sliding groove, which facilitates the fixation of the bottom of the device and ensures the stability of the sliding of multiple first and second connecting rods. During the upward movement of the first pressing sleeve, it also drives the second pressing sleeve to move upward, increasing the range of pressing on the slope.

[0029] 3. As the distance between two adjacent first pressing sleeves gradually increases, the track wound on the unwinding and rewinding mechanisms is stretched. The area traversed by the first pressing sleeve is then pressed by the track. The track is malleable, which not only adapts to different terrains but also provides further protection.

[0030] 4. Through the cooperation of sliding blocks, cone blocks, wedge blocks, and elastic elements, after the tracks are deployed, the cone blocks can be inserted into the ground, which facilitates the reinforcement of deep slopes and further protects the slopes, resulting in good performance.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1 - Figure 4 The present invention provides a technical solution: a safety protection device for the construction of grouted rubble masonry slope protection, including a slope protection structure 1 and an outer shell 2 set on one side of the slope protection structure 1. The outer shell 2 is a protective device for the slope protection structure 1, used to reduce the main geological disasters that may occur during the construction of the slope protection structure 1, such as surface collapse and mudflow erosion.

[0041] It also includes a reinforcement mechanism 3, which is disposed on one side of the outer shell 2. The reinforcement mechanism 3 includes a connecting rod structure 31 disposed on one side of the outer shell 2 and a fixing block 32 rotatably mounted on the upper and lower ends of the connecting rod structure 31.

[0042] The linkage structure 31 includes a first linkage 311 rotatably mounted on one side of the outer casing 2 and a second linkage 312 rotatably mounted on one side of the outer casing 2. The first linkage 311 and the second linkage 312 are rotatably connected.

[0043] The upper two fixed blocks 32 are each fixedly mounted with a first sliding rod 33, and the lower ends of the lower two fixed blocks 32 are each rotatably mounted with a second sliding rod 36. The middle of the two second sliding rods 36 is threadedly connected to a threaded rod 4. The threaded rod 4 has the connecting rod structure 31 as the midpoint, and the threads on both sides rotate in opposite directions. One end of the threaded rod 4 is connected to a motor, which is fixed on the outer shell 2. After the motor is turned on, the threaded rod 4 can rotate. The outer wall of the first sliding rod 33 is rotatably connected to a first pressing sleeve 5.

[0044] In this embodiment: In the initial state, the two fixing blocks 32 are located on both sides of the threaded rod 4. The width of the first connecting rod 311 and the second connecting rod 312 is relatively large. Multiple connecting rod structures 31 are folded together. When using this device, first move the outer shell 2 to one side of the slope, rotate the connecting rod structure 31 on the outside of the outer shell 2 and press it against the slope to adapt to slopes with different gradients. At this time, turn on the motor, the threaded rod 4 rotates, the two fixing blocks 32 move closer to each other, and the folded first connecting rod 311 and the second connecting rod 312 rotate, gradually increasing in height. During this process, the first pressing sleeve 5 also rolls upward continuously, which plays a role in compacting the loose soil on the slope surface, improving the looseness and unevenness of the slope surface, and reinforcing the slope surface.

[0045] When the first connecting rod 311, the second connecting rod 312 and the first pressing sleeve 5 move to the highest point, there is a certain space between the adjacent first pressing sleeves 5. The slope surface in the space has been pressed and tightened by the first pressing sleeve 5, with high surface flatness, strong integrity and relatively compact geology. Combined with the mortar-grouted rubble masonry to reinforce the slope, the protection effect on the slope is further increased.

[0046] This device protects the slope by moving the first connecting rod 311, the second connecting rod 312, and the first pressing sleeve 5 from bottom to top, thus reinforcing the bottom of the slope. As the upper part of the slope gradually stabilizes, the device, with the first pressing sleeve 5 distributed in a point-like manner on the slope, easily avoids uneven areas on the slope surface, providing excellent reinforcement and greatly reducing the risk of surface landslides and mudflows.

[0047] Example 2: Please refer to the figure. Figure 3 - Figure 5 The outer shell 2 has movable wheels 21 rotatably installed at both ends, and a connecting block 22 is fixedly installed on one side of the outer shell 2. One end of the threaded rod 4 is rotatably connected to the connecting block 22. An inner baffle 23 is also fixedly installed inside the outer shell 2, and a sliding groove 24 is provided on the inner baffle 23.

[0048] The outer casing 2 is moved by the movable wheels 21.

[0049] A first I-shaped wheel 35 is fixedly installed at one end of the first sliding rod 33. A first inner groove 331 is opened inside the first sliding rod 33. A first inner rod 332 is connected between two adjacent first sliding rods 33. The two ends of the first inner rod 332 are slidably installed in the first inner groove 331. The first inner rod 332 is slidably installed in two first pressing sleeves 5.

[0050] A pressing mechanism 7 is connected between the two first I-shaped wheels 35. The pressing mechanism 7 is rotatably installed on the second pressing sleeve 71 at the end of the first pressing sleeve 5 away from the first sliding rod 33. A second inner rod 72 is slidably installed between two adjacent second pressing sleeves 71.

[0051] Both the first link 311 and the second link 312 are provided with sliding grooves 313, and sliders 314 are slidably installed on the sliding grooves 313. A stabilizing rod 315 is fixedly installed on both sliders 314.

[0052] In this embodiment: through the cooperation between the first sliding rod 33, the first I-shaped wheel 35, the first inner groove 331, the first inner rod 332 and the first pressing sleeve 5, during the sliding process of the first connecting rod 311 and the second connecting rod 312, the distance between the two fixed blocks 32 is increased, and the first inner rod 332 adaptably slides in the first inner groove 331. At the same time, the two sliders 314 of the stabilizing rod 315 also slide about the sliding groove 313, which facilitates the fixation of the bottom of the device and ensures the stability of the sliding of the multiple first connecting rods 311 and the second connecting rod 312.

[0053] As the first pressing sleeve 5 moves upward, it also drives the second pressing sleeve 71 to move upward, increasing the range of pressing on the slope. The second pressing sleeve 71 and the second inner rod 72 slide left and right, which facilitates the adaptation to the rotation of the first connecting rod 311 and the second connecting rod 312, improves the stability of the sliding of multiple first pressing sleeves 5, and ensures that the first pressing sleeve 5 and the second pressing sleeve 71 can continuously roll on the slope.

[0054] Example 3: Please refer to Figure 3 - Figure 6 The second sliding rod 36 is rotatably mounted with a second I-shaped wheel 37. The second sliding rod 36 is connected to a third sliding rod 38 through a connecting rod structure 31. One end of the third sliding rod 38 is connected to an unwinding mechanism 34. A track 6 is wound on the unwinding mechanism 34. One end of the track 6 is also attached to the second I-shaped wheel 37 and the first I-shaped wheel 35.

[0055] A winding mechanism 8 is provided on one side of the second I-shaped wheel 37. The winding mechanism 8 includes a central rod 81 fixedly installed between two connecting blocks 22 and a winding roller 84 fixedly installed on the central rod 81. One end of the track 6 is wound around the winding roller 84. A connecting sleeve 83 is provided at one end of the winding roller 84. A spiral spring 82 is installed between the connecting sleeve 83 and the central rod 81.

[0056] In this embodiment, the unwinding mechanism 34 and the winding mechanism 8 have the same structure. In the initial state, the first connecting rod 311 and the second connecting rod 312 are folded together, and multiple first I-shaped wheels 35 are connected to the second I-shaped wheels 37. The track 6 is wrapped around the unwinding mechanism 34 and the winding mechanism 8, and passes around the second I-shaped wheel 37 and the first I-shaped wheel 35 in sequence.

[0057] As the distance between two adjacent first pressing sleeves 5 gradually increases, the first I-shaped wheel 35 and the second I-shaped wheel 37 gradually separate from each other. The track 6, which is wound around the unwinding mechanism 34 and the winding mechanism 8, is stretched, and the spiral spring 82 gradually relaxes. The area that the first pressing sleeve 5 has traveled through is then pressed again by the track 6. The track 6 is malleable and can not only adapt to different terrains, but also further play a protective role. By setting the spiral spring 82, when the first connecting rod 311 and the second connecting rod 312 are relaxed, the track 6 can be rewound, which is convenient for multiple uses.

[0058] Example 4: Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 Multiple through holes 61 are equidistantly provided on the track 6, and a clearance groove 62 is provided at the other end of the track 6. The clearance groove 62 is connected to the through holes 61, and the diameter of the clearance groove 62 is larger than the diameter of the through holes 61.

[0059] The track 6 is also equipped with a gripping mechanism 9, which includes a sliding block 91 slidably mounted on the through hole 61, a conical block 92 fixedly mounted on one end of the sliding block 91, and a wedge block 93 fixedly mounted on the end of the sliding block 91 away from the conical block 92. An elastic element 94 is connected between the wedge block 93 and the wall of the clearance groove 62. The elastic element 94 can be composed of any elastic mechanism such as a spring or a metal sheet.

[0060] Through the cooperation of sliding block 91, cone block 92, wedge block 93, and elastic element 94, after the track 6 is deployed, the cone block 92 can be inserted into the ground, which is convenient for reinforcing deep slopes. The track 6 slides over the first I-shaped wheel 35 and the second I-shaped wheel 37. One end of the wedge block 93 contacts the first I-shaped wheel 35 and the second I-shaped wheel 37. The first I-shaped wheel 35 and the second I-shaped wheel 37 press against the wedge block 93, and the elastic element 94 is compressed. The sliding block 91 and the cone block 92 move towards the slope, so that the cone block 92 is further embedded in the ground, which further protects the slope and has a good effect.

[0061] This invention also discloses an installation method for a safety protection device used in the construction of steep slope masonry rubble masonry slope protection, comprising the following steps:

[0062] S1: First, move the outer shell 2 to one side of the slope protection, and then the connecting block 2 abuts against one side of the slope protection;

[0063] S2: The track 6 is respectively fitted onto the unwinding mechanism 34, the second I-beam wheel 37, the first I-beam wheel 35 and the winding mechanism 8;

[0064] S3: Turn on the motor, the threaded rod 4 rotates, the two fixed blocks 32 on the left and right move closer to each other, the first connecting rod 311 and the second connecting rod 312 after folding rotate, and the height gradually increases. During this process, the first pressing sleeve 5 and the second pressing sleeve 71 also roll upward continuously to roll the slope.

[0065] S4: Track 6 unfolds, and cone block 92 is further driven into the ground to further reinforce the slope;

[0066] S5: The drive motor reverses, the first link 311 and the second link 312 reset and fold, the track 6 resets, and the outer shell 2 is removed.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
