Description

Technical Field

[0001] This invention relates to the field of slope stabilization device technology, specifically a highway subgrade protection device. Background Technology

[0002] Highway subgrade protection devices are applied to the slopes of highway subgrades to prevent slope collapse, ensure the stability of the highway subgrade during use, maintain the condition of the highway subgrade under the influence of the natural environment, and provide basic protection for highway traffic safety.

[0003] Patent application CN202123336566.6 discloses a highway subgrade protection device, applied in the field of subgrade protection technology. It is installed on a subgrade slope, which has a drainage ditch and several overflow pipes. An mounting base is located on the side of the subgrade slope away from the highway from the drainage ditch, and several slope protection devices are located on the side of the mounting base facing away from the highway. The slope protection device includes a protective mechanism for protecting the subgrade slope and a driving mechanism for driving the protective mechanism, both of which are mounted on the mounting base.

[0004] During long-term use, the protective devices of highway subgrade may experience soil settlement, causing the anchor bolts to be subjected to force, disrupting the original force balance of the anchor bolts, resulting in loosening of the anchor bolts within the soil layer, reducing the anchoring effect, and affecting the stability and protective function of the slope. Summary of the Invention

[0005] The purpose of this invention is to provide a roadbed protection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roadbed protection device, comprising an anchor rod, a guide sleeve welded to the outer wall of the anchor rod, a connecting rib welded to the outer wall of the guide sleeve, a slot opened on the outer wall of the anchor rod, and an expansion mechanism provided inside the anchor rod;

[0007] The expansion mechanism includes a sliding rod, the outer wall of which is inserted into the inner wall of the anchor rod. A second slot is formed on the outer wall of the sliding rod, and an expansion anchor is hinged to the second slot via a rotating shaft. A guide block is fixedly connected to the inner wall of the sliding rod, and a support rod is slidably connected to the inner wall of the guide block. A second spring is fixedly connected to the inner wall of the guide block, and the other end of the second spring is fixedly connected to the outer wall of the support rod. The expansion anchor is used for anchoring within the soil layer. By setting up the expansion mechanism, expansion and anchoring are performed within the anchor hole, and the anchor rod is limited, increasing the anchor rod's firmness within the anchor hole and preventing loosening of the anchor rod due to soil settlement over long-term use. This increases the service life of the roadbed protection device for roadside slope protection.

[0008] According to the above technical solution, the outer wall of the anchor rod is provided with an anti-detachment hook, which is in contact with the soil layer to increase the anchoring force between the anchor rod and the soil layer. The inner wall of the anchor rod is provided with a guide groove, which is used to guide the expansion anchor.

[0009] According to the above technical solution, the outer wall of the sliding rod slides along the inner wall of the guide sleeve, the outer wall of the support rod penetrates the second slot and contacts the inner wall of the expansion anchor, the support rod is used to support the expansion anchor, and a spring is fixedly connected to the outer wall of the sliding rod, the other end of the spring is fixedly connected to the inner wall of the anchor rod, and the spring is used to support the sliding rod.

[0010] According to the above technical solution, an interception mechanism is provided on the outer wall of the connecting bar. The interception mechanism includes a fixing block, the inner wall of which is fixedly connected to the outer wall of the connecting bar. An interception plate is hinged to the outer wall of the fixing block via a rotating shaft. The interception plate is bent and is used to intercept and guide falling rocks and rainwater. By setting up the interception mechanism, rainwater is intercepted and guided, reducing the amount of rainwater flowing into the anchor hole and preventing corrosion damage to the anchor rod, which would affect the anchoring effect. This increases the service life of the roadbed protection device for the slope. At the same time, the interception mechanism also intercepts debris rolling down the slope. The system intercepts and collects impurities, increasing the safety of pedestrians and vehicles and reducing the accumulation of impurities in downstream drainage ditches, which would affect drainage. Through the cooperation of the expansion mechanism and the interception mechanism, the impact force received by the interception mechanism when intercepting falling rocks is transmitted to the soil layer for stress relief. The impact force generated when intercepting falling rocks increases the expansion embedment depth of the expansion mechanism in the soil layer and applies stress to the soil layer, increasing the anchoring firmness of the roadbed protection device in the soil layer. At the same time, it prevents the anchor rod from loosening in the anchor hole due to the release of soil stress after long-term use of the roadbed protection device.

[0011] According to the above technical solution, the outer wall of the intercepting plate is provided with a sliding groove. The groove wall is slidably connected to the outer wall of the sliding rod through a slider. The sliding groove swings on the outer wall of the fixed block due to the impact force of the falling rocks intercepted by the intercepting plate, which drives the sliding rod to slide on the inner wall of the anchor rod.

[0012] According to the above technical solution, a reinforcing rib is fixedly connected to the outer wall of the interception plate, and a reinforcing rib is fixedly connected to the inner wall of the interception plate. The reinforcing rib and the reinforcing rib are used to increase the strength of the interception plate, and the reinforcing rib is used to guide the falling rocks and rainwater.

[0013] According to the above technical solution, the inner wall of the interceptor plate is provided with a flow guide groove, which is used to guide rainwater. The bottom of the flow guide groove wall is provided with a flow guide hole, which is used to guide rainwater.

[0014] According to the above technical solution, the outer wall of the connecting bar is covered with cement, and the hollow part of the connecting bar is filled with hollow bricks for reinforcing the slope soil. The expansion anchor is made of rust-proof material. The opening position of the second slot matches the opening position of the first slot. The first slot is used to guide and limit the expansion anchor. The expansion anchor is supported by a support rod and is guided by the first slot to open towards the soil layer in the first slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention increases the firmness of the anchor rod in the anchor hole by setting an expansion mechanism to expand and anchor the anchor rod in the anchor hole and limit the anchor rod. This prevents the anchor rod from loosening in the soil layer due to soil settlement after long-term use, and increases the service life of the roadbed protection device for roadside slope protection.

[0017] 2. This invention utilizes the cooperation of an expansion mechanism and an interception mechanism. When the interception mechanism intercepts falling rocks, the impact force is transmitted into the soil layer for stress relief. The impact force generated during rock interception increases the expansion embedment depth of the expansion mechanism in the soil layer and applies stress to the soil layer, thereby increasing the anchoring firmness of the roadbed protection device in the soil layer. At the same time, it prevents the anchor rod from loosening in the anchor hole due to the release of soil stress after long-term use of the roadbed protection device.

[0018] 3. This invention intercepts and diverts rainwater by setting up an interception mechanism, reducing the amount of rainwater flowing into the anchor holes and preventing corrosion damage to the anchor rods, which would affect the anchoring effect and increase the protection life of the roadbed protection device for the slope.

[0019] 4. This invention intercepts and collects debris rolling down the slope using an interception mechanism, increasing the safety of pedestrians and vehicles and reducing the accumulation of debris in downstream drainage channels, thus minimizing drainage impact. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a roadbed protection device, including an anchor rod 100, a guide sleeve 102 welded to the outer wall of the anchor rod 100, a connecting bar 101 welded to the outer wall of the guide sleeve 102, a slot 104 opened on the outer wall of the anchor rod 100, an anti-disengagement hook 103 opened on the outer wall of the anchor rod 100, the anti-disengagement hook 103 is in contact with the soil layer, used to increase the anchoring force between the anchor rod 100 and the soil layer, a guide groove 105 opened on the inner wall of the anchor rod 100, and the outer wall of the connecting bar 101 is covered with cement;

[0033] An interception mechanism 200 is provided on the outer wall of the connecting rib 101;

[0034] During long-term use, soil settlement causes anchor bolts 100 to be subjected to force, disrupting their original force balance and causing them to loosen within the soil. This reduces the anchoring effect and affects the stability and protective function of the slope. Therefore, an interception mechanism 200 is installed to intercept and divert rainwater, reducing the amount of rainwater flowing into the anchor holes and preventing corrosion damage to the anchor bolts 100, thus improving the anchoring effect and increasing the lifespan of the roadbed protection device for the slope. At the same time, the interception mechanism 200 intercepts and collects debris rolling down the slope, increasing the safety of pedestrians and vehicles and reducing the accumulation of debris in downstream drainage ditches, which would affect drainage.

[0035] The interception mechanism 200 includes a fixed block 201, the inner wall of which is fixedly connected to the outer wall of the connecting rib 101. An interception plate 202 is hinged to the outer wall of the fixed block 201 via a rotating shaft. The interception plate 202 is bent and is used to intercept and guide falling rocks and rainwater. A sliding groove 203 is provided on the outer wall of the interception plate 202. The groove wall is slidably connected to the outer wall of the sliding rod 301 via a slider. The sliding groove 203 oscillates on the outer wall of the fixed block 201 due to the impact force of the falling rocks intercepted by the interception plate 202. The sliding rod 301 slides on the inner wall of the anchor rod 100. The outer wall of the intercepting plate 202 is fixedly connected with a reinforcing rib 1 204, and the inner wall of the intercepting plate 202 is fixedly connected with a reinforcing rib 207. The reinforcing rib 1 204 and the reinforcing rib 207 are used to increase the strength of the intercepting plate 202. The reinforcing rib 207 is used to guide the falling rocks and rainwater. The inner wall of the intercepting plate 202 is provided with a guide groove 205, which is used to guide the rainwater. The bottom of the guide groove 205 is provided with a guide hole 206, which is used to guide the rainwater.

[0036] When the roadbed protection device is put into use, the anchor rod 100 is placed in the pre-set anchor hole on the slope, and the guide sleeve 102 is exposed outside the anchor hole. The connecting rib 101 is welded to the outer wall of the guide sleeve 102, so that the guide sleeve 102 is supported by the connecting rib 101. After the connecting rib 101 is welded, the outer wall of the connecting rib 101 is covered with cement to protect the connecting rib 101. When the falling rock rolls down the slope, the falling rock is intercepted by the intercepting plate 202. The impact force generated by the falling rock on the inner wall of the intercepting plate 202 after contact with the inner wall of the intercepting plate 202 causes the intercepting plate 202 to swing away from the anchor rod 100 on the outer wall of the fixed block 201. At the same time, the sliding rod 301 is guided and limited by the sliding groove 203, so that the sliding rod 301 slides away from the anchor rod 100 on the inner wall of the anchor rod 100, thus dissipating the impact force generated by the falling rock. The falling rock is guided by the intercepting plate 202 and the reinforcing rib 207 and falls into the diversion groove 205. The interceptor plate 202 collects and prevents falling rocks from rolling down the slope and causing injury to pedestrians and vehicles. When impacted by falling rocks, the interceptor plate 202 is supported by reinforcing ribs 207 and 204 to prevent deformation and ensure usability. During the rainy season, the interceptor plate 202 intercepts and diverts rainwater, directing it to the inner wall of the interceptor plate 202 and then through reinforcing ribs 207 to the inside of the diversion channel 205 for collection. This reduces rainwater flow into the anchor holes and prevents corrosion damage to the anchor rods 100. Simultaneously, the rainwater collected in the diversion channel 205 is diverted through the diversion holes 206, flowing out from the bottom of the interceptor plate 202 and towards the inner wall of a downstream set of interceptor plates 202, eventually reaching the drainage ditch. The interceptor plate 202 also intercepts and collects fallen branches and leaves from the slope, reducing impurities in the downstream drainage ditch and preventing excessive accumulation of impurities that could impede drainage.

[0037] Example 2, based on Example 1, please refer to... Figures 7-10 The present invention provides a technical solution: an expansion mechanism 300 is provided inside the anchor rod 100;

[0038] During long-term use, soil settlement can cause anchor bolts 100 to be subjected to stress, disrupting their original force balance and leading to loosening within the soil. This reduces the anchoring effect and affects the stability and protective function of the slope. Therefore, an expansion mechanism 300 is installed in the anchor hole for expansion anchoring and to limit the anchor bolts 100, increasing their firmness within the anchor hole and preventing loosening due to soil settlement over time. This enhances the protection of the roadside slope by improving the overall effectiveness of the roadbed protection system. The service life of the slope protection is extended. At the same time, the expansion mechanism 300 works in conjunction with the interception mechanism 200. When the interception mechanism 200 intercepts falling rocks, the impact force is transmitted to the soil layer through the expansion mechanism 300 to release the force. The impact force generated when the falling rocks are intercepted increases the expansion embedment depth of the expansion mechanism 300 in the soil layer and applies stress to the soil layer, increasing the anchoring firmness of the roadbed protection device in the soil layer. At the same time, it prevents the anchor rod 100 from loosening in the anchor hole due to the release of soil stress after long-term use of the roadbed protection device.

[0039] The expansion mechanism 300 includes a sliding rod 301, the outer wall of which is inserted into the inner wall of the anchor rod 100. A slot 304 is formed on the outer wall of the sliding rod 301, and an expansion anchor 303 is hinged to the slot wall via a rotating shaft. A guide block 305 is fixedly connected to the inner wall of the sliding rod 301, and a support rod 306 is slidably connected to the inner wall of the guide block 305. A spring 307 is fixedly connected to the inner wall of the guide block 305, and the other end of the spring 307 is fixedly connected to the outer wall of the support rod 306. The expansion anchor 303 is used for anchoring within the soil layer, and the guide groove 105 is used to guide the expansion anchor 303. The outer wall of the sliding rod 301 slides along the inner wall of the guide sleeve 102. The outer wall of the support rod 306 penetrates through the second groove 304 and contacts the inner wall of the expansion anchor 303. The support rod 306 is used to support the expansion anchor 303. The outer wall of the sliding rod 301 is fixedly connected to the first spring 302. The other end of the first spring 302 is fixedly connected to the inner wall of the anchor rod 100. The first spring 302 is used to support the sliding rod 301. The expansion anchor 303 is made of rust-proof material. The opening position of the second groove 304 matches the opening position of the first groove 104. The first groove 104 is used to guide and limit the expansion anchor 303. The expansion anchor 303 is supported by the support rod 306 and guided by the first groove 104 to open towards the soil layer within the first groove 104.

[0040] After the anchor rod 100 is fixed in the pre-set anchor hole on the slope, the sliding rod 301 is inserted into the anchor rod 100 through the guide sleeve 102. The sliding rod 301 is rotated to align the expansion anchor 303 with the guide groove 105. The sliding rod 301 is then inserted to the bottom of the anchor rod 100. The expansion anchor 303 is then supported by the spring 307 on the support rod 306, causing the expansion anchor 303 to enter the groove 104 and open within the groove 104. Upon contact with the soil layer, the sliding rod 301 is supported by the spring 302, which pulls the sliding rod 301, causing it to slide away from the anchor rod 100. The expansion anchor 303 is guided by the slot 104, allowing it to extend into the soil layer and open for anchoring. When the falling rock is intercepted by the intercepting plate 202, the impact force on the intercepting plate 202 causes it to hinge away from the anchor rod 100 via the fixing block 201. The sliding rod 301 slides within the sliding groove 203, guided by the direction of the swing of the intercepting plate 202. Simultaneously, the sliding rod 301 slides away from the anchor rod 100 along the inner wall of the anchor rod 100, increasing the opening angle of the expansion anchor 303 within the soil layer and increasing the anchoring force of the expansion anchor 303 on the anchor rod 100 within the soil layer. When the intercepting plate 202 is impacted, the force is transmitted through the sliding rod 301 to the expansion anchor 303 within the soil layer for stress relief, allowing the intercepting plate 202 to intercept falling rocks. Simultaneously, during the stress relief process, the reverse impact force generated on the intercepting plate 202 is transmitted through the fixing block 201 to the connecting reinforcement 101 for stress relief, increasing the embedment depth of the cement covering the outer wall of the connecting reinforcement 101 into the soil layer, increasing the protection strength of the highway subgrade protection device for the slope, and providing stronger support against slope slippage.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended technical solutions and their equivalents.
