A type of slope soil reinforcement and protection net

Abstract

This invention relates to the field of slope protection technology, specifically to a slope soil reinforcement and protection net, comprising a stitched net, fixing blocks, fixing buckles, movable buckles, fastening nuts, fastening components, locking components, and warning components. By setting up movable buckles and fastening blocks, the invention allows the stitched net to be tightened during installation by rotating the fastening nuts, which, in conjunction with the fastening components, drive the fastening blocks and movable buckles to move relative to each other. Once the net is tightened to a suitable tension, the locking components lock the fastening blocks, thus fixing the stitched net to the support rope. This prevents slope collapse caused by soil erosion after coal mining. The warning components provide timely alarms or warnings when soil erosion leads to rockfall, facilitating timely intervention or replacement by workers, reducing slope maintenance costs, and ensuring effective protection against soil erosion.

Description

Technical Field

[0001] This invention relates to the field of slope protection technology, specifically a slope soil reinforcement and protection net. Background Technology

[0002] Human activities such as mining resources like ores, coal, oil, water, and building materials, as well as construction activities like excavation and backfilling of soil and rock during railway, highway, water conservancy, mining, tunnel, and building projects, have created numerous exposed steep rock slopes. These activities have led to severe imbalances in the original environment and ecosystems. Furthermore, these human activities often cause geological disasters such as ground subsidence, landslides, collapses, and soil erosion. Therefore, using slope protection nets can effectively prevent landslides, collapses, and soil erosion.

[0003] Slope protection nets primarily function systematically to prevent rockfalls or contain them within a certain area. During slope soil and water conservation, it's necessary to protect the soil to prevent landslides and erosion caused by rain. Existing slope protection nets typically consist of individual mesh panels sewn together, with anchor bolts securing the support ropes to the slope. Specifically, loops are first fixed to the anchor bolt locations on the net. The anchor bolts are then inserted through these loops into the slope, and the loops are welded to secure them. Finally, the large net is sewn onto the support ropes to form a unified protection system. When slope collapses due to soil erosion, the net can intercept the falling debris, thus providing protection. While existing protective netting can intercept gravel, the intercepted gravel remains inside the netting, requiring regular manual cleaning and reinforcement, as well as regular checks on the netting's strength. Otherwise, the accumulation of gravel over time can easily damage the netting, creating safety hazards. Because existing protective netting typically consists of individual pieces sewn together, replacing the entire netting is necessary when only a section is damaged, resulting in lengthy and costly repairs. In contrast, a slope protection netting technology, such as the one described in patent CN215669579U, divides the slope protection netting into a first netting body and several second netting bodies connected by a detachable mechanism. When a section of the slope protection netting is damaged, the damaged section can be disassembled and replaced with a new, complete netting body, thus completing the repair without replacing the entire netting and reducing costs.

[0004] While existing technologies have solved the problem of high maintenance costs associated with large, stitched-together slope protection nets requiring complete replacement when damaged, there are still challenges. During the use of slope protection nets, when rockfalls cause damage requiring replacement, or when rockfalls have trapped a large amount of debris requiring clearing, the large and steep slopes make it difficult for maintenance personnel to immediately identify the anomalies. This necessitates close-range, slow searching and inspection, increasing manpower costs and creating safety hazards that compromise the effectiveness of slope protection.

[0005] Therefore, a slope soil reinforcement and protection net is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a slope soil reinforcement and protection net, which solves the problems of existing slope protection nets being made of a single piece, which cannot be replaced individually when damaged, resulting in high usage costs, and the difficulty in detecting abnormalities or damage to the protection net in a timely manner, leading to safety hazards during the use of slope protection nets.

Detailed Implementation

[0031] To ensure a clear and complete description of the technical solutions in the embodiments of the present invention, and to make the features and advantages more apparent and understandable, the specific implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 6This invention provides a slope soil reinforcement and protection net, including an anchor rod 1 and a support rope 2, as well as a stitched net 3, a fixing block 4, a fixing buckle 5, a movable buckle 6, a fastening nut 7, a fastening component 10, a locking component 20, and a warning component 30. The stitched net 3 is located on the side of the support rope 2, the fixing block 4 is connected between the stitched net 3 and the support rope 2, the fixing buckle 5 is located on the right side of the fixing block 4, the movable buckle 6 is slidably connected to the left side of the fixing block 4, the fastening nut 7 is located at the upper end of the fixing block 4, and the fastening component 10 is located at the fastening nut 7. At the lower end of the mother 7, the fastening component 10 drives the movable buckle 6 to move and tighten the sewing net 3 when the fastening nut 7 rotates forward. The locking component 20 is set inside the fixing block 4. After the sewing net 3 is tightened and fixed, the locking component 20 works with the fastening component 10 to lock the movable buckle 6. The warning component 30 is set inside the fixing block 4. When the sewing net 3 is tightened and fixed and deformed or damaged during use, the warning component 30 works with the movable buckle 6 to issue a corresponding warning. When the sewing net 3 is damaged, it is easy to unlock the movable buckle 6 with the fastening nut 7.

[0034] Specifically, the four corners of the sewn mesh 3 are equipped with fixing ropes 11. When it is necessary to fix the sewn mesh 3 to the support rope 2, the four corners of the sewn mesh 3 can be fastened to the anchor rod 1 with the fixing ropes 11 to reinforce the four corners. At the same time, it is convenient to fasten the four sides of the sewn mesh 3 to the support rope 2 later.

[0035] Specifically, a base 12 is provided at the lower end of the fixing block 4. The fixing block 4 and the base 12 are fastened together by bolts. When installing the fixing block 4, the operator first places the base 12 at the lower end of the support rope 2, then fastens the fixing block 4 onto the base 12 and the support rope 2, and then uses bolts to fasten the base 12 and the support rope 2, thus fixing the fixing block 4 onto the support rope 2.

[0036] Fastening component 10 includes fastening block 101, fastening spring 102, movable baffle 103, fastening gear 104, fastening rack 105, lower connecting cylinder 106, upper connecting cylinder 107, connecting ring 108, central column 109, and release unit 40. Fastening block 101 is slidably connected to fixed block 4, and its sliding direction is left and right. A fixing spring 101a is provided between the right end of fastening block 101 and the inner wall of fixed block 4. 1a has a small elastic force, which ensures that the fastening block 101 can be pushed to the left to reset without being limited by the gear. The fastening block 101 has a fastening groove 101b, and the movable buckle 6 is slidably connected in the fastening groove 101b. The movable baffle 103 is set on the movable buckle 6. The fastening spring 102 is set between the left end of the movable baffle 103 and the fastening block 101. The fastening rack 105 is set at the rear end of the fastening block 101. The fastening gear 104 is rotatably connected to the fixed block 4. The fastening gear 104 meshes with the fastening rack 105. The lower connecting cylinder 106 is fixedly connected to the upper end of the fastening gear 104. The central column 109 is fixedly connected to the lower end of the fastening nut 7. The upper connecting cylinder 107 is slidably connected to the central column 109. Its sliding direction is up and down. The upper connecting cylinder 107 and the central column 109 rotate coaxially. The connecting ring 108 is set at the upper end of the upper connecting cylinder 107. A connecting spring (not shown in the figure) is connected between the upper end of the connecting ring 108 and the lower end of the fastening nut 7. The connecting spring is used to be squeezed when the connecting ring 108 moves upward, so as to provide a downward elastic force to the connecting ring 108 and facilitate subsequent reset. The disengagement unit 40 is set at the upper end of the fastening gear 104. It is used to connect the fastening nut 7 and the fastening gear 104 and automatically disconnect the connection between the fastening nut 7 and the fastening gear 104 after the sewing net 3 is tightened.

[0037] Specifically, the fastening nut 7 is slidably connected to the upper connecting cylinder 107, and the sliding direction is up and down. The fastening nut 7 and the upper connecting cylinder 107 always rotate synchronously. When the fastening nut 7 rotates, the upper connecting cylinder 107 will rotate together with the fastening nut 7.

[0038] The disengagement unit 40 includes a connecting block 401 disposed on the outside of the upper connecting cylinder 107 and a connecting groove 402 disposed in the lower connecting cylinder 106. The connecting groove 402 cooperates with the connecting block 401. The cooperation here means that the connecting block 401 and the connecting groove 402 have a certain inclination angle, which is greater than 45° and less than 80°. When the connecting block 401 is inserted into the connecting groove 402, the upper connecting cylinder 107 drives the connecting block 401 to rotate in the inclination direction of the connecting block 401. Under the cooperation of the connecting block 401 and the connecting groove 402, the upper connecting cylinder 107 can drive the lower connecting cylinder 106 to rotate together. During the rotation in this direction, after the connecting block 401 is subjected to a certain resistance from the connecting groove 402, the connecting block 401 can slide upward along the inclination surface of the connecting groove 402 and out of the upper end of the lower connecting cylinder 106.

[0039] The locking component 20 includes a locking groove 201, a locking block 202, and a locking spring 203. The locking groove 201 is located at the rear end of the fastening gear 104. The locking block 202 is slidably connected within the locking groove 201. A locking chamfer 204 is provided at the front end of the locking block 202. The locking chamfer 204 engages with the fastening gear 104. This engagement means that when the fastening gear 104 rotates forward, the teeth of the fastening gear 104 can push the locking block 202 upward along the locking chamfer 204 to compress the locking spring 203. When the fastening gear 104 tends to rotate in reverse, the locking chamfer 204 will reset and insert into the teeth of the fastening gear 104 under the action of the locking spring 203, so that the fastening gear 104 is limited by the side of the locking block 202 away from the locking chamfer 204 and cannot rotate in reverse.

[0040] Working principle: When fixing the stitched net 3, the operator first fixes the anchor rod 1 to the slope, then fixes the support rope 2 to the anchor rod 1, and then fixes the corresponding number of fixing blocks 4 to the support rope 2 in each area. In this embodiment, three sets of fixing blocks 4 are fixed on each side of the stitched net 3, depending on the size of the stitched net 3 and the required protection strength of the slope. When fixing the stitched net 3, the operator first ties the fixing rope 11 at the four corners of the stitched net 3 to the corresponding anchor rod 1 at the four corners, then fixes one side of the stitched net 3 to the fixing buckle 5, and finally fixes the side of the stitched net 3 away from the fixing buckle 5 to the movable buckle 6 of the corresponding fixing block 4. Then the operator uses an electric drill to connect the movable buckle 6 to the stitched net 3. Tightening the fixing block 4 and fastening nut 7 causes the fastening nut 7 to rotate clockwise, driving the upper connecting cylinder 107 to rotate clockwise. The upper connecting cylinder 107, in conjunction with the connecting block 401 and the connecting groove 402, drives the lower connecting cylinder 106 to rotate clockwise. The clockwise rotation of the lower connecting cylinder 106 drives the lower fastening gear 104 to rotate clockwise. Finally, the fastening block 101, in conjunction with the fastening rack 105 and the fastening gear 104, moves away from the sewing mesh 3, that is, slides to the right as shown in the diagram. When the fastening block 101 slides to the right, it squeezes the fixing spring 101a and drives the movable buckle 6 inside it to move to the right. At this time, since the other end of the sewing mesh 3 is fixed by the fixing buckle 5, the fastening block 101 drives the movable buckle 6 to move to the right until... After a certain distance, the movable buckle 6 will tighten the stitched mesh 3. As the fastening block 101 continues to move to the right, the movable buckle 6, tightened by the stitched mesh 3, will stop moving with the fastening block 101. The fastening block 101 will move to the right relative to the movable buckle 6 and squeeze the fastening spring 102 between the movable baffle 103 and the fastening block 101 until the stitched mesh 3 is tightened to a certain force. At this point, the stitched mesh 3 is fully tightened, which can intercept gravel and debris on the slope. At this time, the fastening spring 102 is compressed to a certain extent, and the fastening block 101 is subjected to the reaction force on one side of the movable buckle 6, so that the fastening gear 104 also encounters a certain resistance when rotating. The upper connecting cylinder 107 can no longer rotate. The lower connecting cylinder 106 rotates synchronously. As the fastening nut 7 continues to rotate forward, the connecting block 401 on the side of the upper connecting cylinder will slide upward along the connecting groove 402 on the side of the lower connecting cylinder 106, and finally move the upper connecting cylinder along the connecting groove 402 to the upper end of the lower connecting cylinder 106. At this time, the upper connecting cylinder 107 is no longer synchronously rotating with the lower connecting cylinder 106. Then the operator can pull out the fastening nut 7 with the electric drill. This allows for the installation of slope protection nets without the need for on-site weaving, and the installation is quick. It also ensures that the tension of the stitched net 3 is moderate when it is installed. It will not cause excessive stress on the stitched net 3 due to excessive weaving, which would affect its service life, or it will cause the slope protection to be too loose, which would reduce the protection effect.

[0041] When installing and securing the sewing net 3, after the sewing net 3 is tightened to a certain force, the upper connecting cylinder 107 moves to the upper end of the lower connecting cylinder 106. Under the action of the locking spring 203, the locking block 202 resets and moves forward, so that the locking chamfer 204 is engaged in the tooth gap of the fastening gear 104. The fastening gear 104 is limited by the side of the locking block 202 away from the locking chamfer 204 and cannot reverse. Thus, after the sewing net 3 is tightened to a certain force, the locking component 20 can automatically lock the fastening block 101 and the locking buckle, thereby fixing the sewing net 3 to the support rope 2.

[0042] Example 2

[0043] Please see Figures 4 to 11 A slope soil reinforcement and protection net is provided, including a warning component 30 including a tension warning device 301 and a damage warning unit 302. The tension warning device 301 is installed in a fastening block 101, and a movable baffle 103 cooperates with the tension warning device 301. The damage warning unit 302 is installed in a fixed block 4, and it issues a damage warning when the sewn net 3 is damaged.

[0044] Specifically, the tension warning device 301 is a signal transmitter. The operator can set up a signal receiver near the slope. When a rockfall occurs on the slope, or when branches and leaves accumulate and are trapped inside the stitched net 3, the stitched net 3 will further tighten to a certain state after intercepting these foreign objects to a certain extent. If personnel need to clear the foreign objects inside the slope protection net as soon as possible, otherwise there may be a risk of the net breaking, the stitched net 3 will continue to tighten, causing the movable buckle 6 to move away from the fastening block 101, that is, to the left as shown in the figure. At this time, the fastening spring 10 above the movable buckle 6 will... 2. Further squeezed by the movable baffle 103 and the fixed block 4 until the fastening spring 102 is compressed to its limit, the movable baffle 103 triggers the tension warning device 301 in the fastening block 101, causing the tension warning device 301 to send a signal to the signal receiver near the hillside. This allows the staff to accurately locate the collapse position of the slope protection net based on the transmission position of the tension warning device 301. When facing large slopes, the staff does not need to visually inspect each one to check for risks, achieving accurate and rapid cleanup, increasing the efficiency of slope protection net cleaning and maintenance, and reducing the safety hazard of further slope collapse.

[0045] The damage warning unit 302 includes a trigger block 302a, a trigger chamfer 302b, a push baffle 302c, a push block 302d, a push groove 302e, a filling block 302f, and a lifting module 302g. The trigger block 302a is slidably connected to the right end of the fastening groove 101b, and its sliding direction is front and back. The trigger chamfer 302b is provided on the left side of the front end of the trigger block 302a. The trigger chamfer 302b cooperates with the movable baffle 103. The cooperation here means that when the movable buckle 6 moves to the right relative to the fastening block 101, the movable buckle 6 will gradually bring the movable baffle 103 into contact with the trigger chamfer 302b, and follow the trigger... The chamfer 302b pushes the trigger block 302a backward. The push baffle 302c is slidably connected in the fixed block 4, and its sliding direction is front and back. The front end of the push baffle 302c abuts against the rear end of the trigger block 302a. The push block 302d is located at the rear end of the push baffle 302c. The push groove 302e is located in the fixed block 4. The push block 302d is slidably connected to the fixed groove. A push spring (not shown in the figure) is provided between the rear end of the push baffle 302c and the inner wall of the fixed block 4. The push spring can assist the push baffle 302c to reset forward after it moves backward. The filling block 302f is located behind the push block 302d.

[0046] The lifting module 302g includes a lifting groove 302g-1, a lifting block 302g-2, a lifting spring (not shown in the figure), a filling spring (not shown in the figure), and a warning block 302g-3. A push chamfer 302d-1 is provided above the rear end of the push block 302d. The lifting groove 302g-1 is located at the right end of the fastening gear 104. The lifting block 302g-2 is slidably connected within the lifting groove 302g-1, and its sliding direction is up and down. The lower left end of the lifting block 302g-2 is in contact with the upper end of the connecting ring 108. A filling groove is provided inside the 2nd section. The filling block 302f is slidably connected in the filling groove. The lifting spring is located between the upper end of the lifting block 302g-2 and the inner wall of the fixing block 4. The filling spring is located between the rear end of the filling block 302f and the inner wall of the lifting block 302g-2. The warning block 302g-3 is located at the upper right side of the filling block 302f. The rear end of the pushing block 302d cooperates with the locking block 202 through the filling block 302f. This cooperation means that when the upper connecting cylinder 107 has not moved to the upper end of the lower connecting cylinder 106, the lower end of the lifting block 302g-2 is at... Under the action of the lifting spring, the filling block 302f abuts against the upper end of the connecting ring 108. At this time, the filling block 302f is located between the pushing block 302d and the locking block 202. When the pushing block 302d moves backward, it can fit against the front end of the filling block 302f, pushing the filling block 302f backward to compress the filling spring and causing the rear end of the filling block 302f to fit against the locking block 202, pushing the locking block 202 backward. The lower end of the filling block 302f engages with the pushing chamfer 302d-1. This engagement means that when the upper connecting cylinder 107 moves... When the upper end of the lower connecting cylinder 106 is reached, the connecting ring 108 on the upper connecting cylinder 107 drives the lifting block 302g-2 to move upward and compress the lifting spring. The upward movement of the lifting block 302g-2 drives the filling block 302f to move upward. At this time, when the pushing block 302d moves backward, the upper end of the pushing chamfer 302d-1 can fit with the lower right end of the filling block 302f. As the pushing chamfer 302d-1 moves, the filling block 302f is pushed further upward, so that the filling block 302f can push the warning block 302g-3 out of the fixing block 4.

[0047] Specifically, a damage warning device (not shown in the figure) can also be set around the warning block 302g-3. The damage warning device is also a signal transmitter. When the warning block 302g-3 rises, it can touch the damage warning device, so that the damage warning device can send a different signal than the tension warning device 301 to the signal receiver to remind the staff that the stitching mesh 3 is damaged and needs to be replaced with a new stitching mesh 3.

[0048] The upper end of the fixed block 4 has an unlocking port 8. The warning block 302g-3 slides with the unlocking port 8. A relief port 9 is provided on the rear side of the lower end of the unlocking port 8. The length of the filling block 302f at the unlocking port 8 is greater than the width of the left and right ends of the unlocking port 8. The relief port 9 cooperates with the filling block 302f. This cooperation means that when the upper connecting cylinder 107 has not moved to the upper end of the lower connecting cylinder 106, the filling block 302f is located at the rear end of the pushing block 302d. When the pushing block 302d moves backward, it can push the filling block 302f to move backward. The filling block 302f enters the retraction port 9 and contacts the front end of the locking block 202. When the upper connecting cylinder 107 moves to the upper end of the lower connecting cylinder 106, the filling block 302f is located at the upper rear end of the pushing block 302d. At this time, the rear end of the filling block 302f is in contact with the inner wall of the fixing block 4 above the retraction port 9. When the pushing block 302d drives the pushing chamfer 302d-1 to move backward, the inner wall of the fixing block 4 above the retraction port 9 can support the rear end of the filling block 302f, so that the pushing chamfer 302d-1 can smoothly push the filling block 302f upward.

[0049] A ball bearing (not shown in the figure) is provided on the lower left side of the lifting block 302g-2. The ball bearing is in contact with the upper end of the connecting ring 108. When the connecting ring 108 rotates, the ball bearing can change the sliding friction between the lifting block 302g-2 and the connecting ring 108 into rolling friction.

[0050] The rest of the structure is the same as in Example 1.

[0051] Working principle: When the slope protection net is damaged due to aging after long-term use, or when a large amount of rock and soil is detached from the slope at one time, the stitched net 3 cannot bear the weight and is damaged. At this time, the stitched net 3, which is tightened by the movable buckle 6, breaks. Since the fastening block 101 is locked in the fixed block 4 by the locking block 202, when the stitched net 3 breaks and cannot be tightened, the movable buckle 6 at the break will reset and move to the right under the action of the fastening spring 102, pulling the edge of the stitched net 3, which has the effect of simply tightening the edge, so that the stitched net 3 can still provide a certain degree of protection for the area around the damaged part. When the movable buckle 6 resets to the right, the movable buckle 6 will gradually fit the movable baffle 103 with the trigger chamfer 302b, and push the trigger block 302a backward along the trigger chamfer 302b. The backward movement of the trigger block 302a will drive the push baffle 302c and the push block 302d to move backward and squeeze the push spring. At this time, since the upper connecting cylinder 107 is located above the lower connecting cylinder 106, when the pushing block 302d moves backward, the pushing chamfer 302d-1 at the rear end of the pushing block 302d can contact the lower end of the filling block 302f, and push the filling block 302f upward along the pushing chamfer 302d-1. The upward movement of the filling block 302f pushes the warning block 302g-3 upward, so that the warning block 302g-3 extends out of the fixing block 4 to remind people that the stitched mesh 3 is damaged and needs to be replaced as soon as possible. (It should be noted that when the filling block 302f rises along the pushing chamfer 302d-1, the lower end of the filling block 302f is always in contact with the pushing chamfer 302d-1 until the end, which is convenient for the subsequent replacement of the stitched mesh 3.) This allows the slope protection net to not only reinforce and protect the slope, but also to be promptly discovered by relevant personnel when damage occurs, and the stitched mesh 3 at the damaged location can be replaced.

[0052] When replacing the damaged stitching mesh 3, the operator only needs to remove the edge of the damaged stitching mesh 3 from the movable buckle 6. Then, reverse the fastening nut 7, causing the fastening nut 7 to drive the upper connecting cylinder 107 and the connecting block 401 to reverse until the connecting block 401 is reversed to the connecting groove 402. The connecting block 401 can slide downward along the inclined angle of the connecting groove 402, causing the upper connecting cylinder 107 to drive the connecting ring 108 to move downward and re-engage with the lower connecting cylinder 106. At this time, the upper end of the connecting ring 108 separates from the lower end of the lifting block 302g-2. Then, the operator uses a tool to press down the warning block 302g-3, causing the warning block 302g-3 to drive the filling block 302f downward. The filling block 302f first pushes the chamfer 302d-1 to push the chamfer 302d-1. The push block 302d is pushed forward until the filling block 302f moves completely to the rear end of the push block 302d along the push chamfer 302d-1. At this time, the lower end of the lifting block 302g-2 is in contact with the connecting ring 108, and the filling block 302f moves to the relief opening 9. The operator stops pressing. At this time, the movable buckle 6 in the fastening block 101 moves to the right relative to the fastening block 101 under the action of the fastening spring 102. The movable baffle 103 on the movable buckle 6 pushes the push block 302d backward under the action of the trigger chamfer 302b. The rear end of the push block 302d pushes the filling block 302f into the relief opening 9 and pushes the locking block 202 backward. This unlocks the fastening gear 104 and finally unlocks the fastening block 101 and the fixed block 4.

[0053] When the new stitched net 3 is reinstalled on the support rope 2, the operation in the previous embodiment can be repeated. When the new stitched net 3 is tightened and fixed, when it is tightened to a certain extent, the movable buckle 6 will stop moving, and the fastening block 101 will continue to move to the right, thereby causing the movable baffle 103 on the movable buckle 6 to move to the left relative to the fastening block 101. The movable baffle 103 moves until the left end of the trigger chamfer 302b disengages from the trigger chamfer 302b, so that the push block 302d is reset under the action of the spring, the locking block 202 is reset under the action of the locking spring, and the locking chamfer 204 is engaged with the fastening gear 104. The rest of the principle is the same as in embodiment 1, so that the stitched net 3 can issue an early warning or warning in time when an abnormal condition occurs, and can directly replace the damaged stitched net 3 when it is damaged. The reusability of other parts besides the stitched net 3 further reduces the slope maintenance cost.
