Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of retaining walls, in particular to a connecting structure between a retaining wall and a steel guardrail. Background Technique
[0002] The steel guardrail on the top of the retaining wall is mainly used to improve traffic safety, prevent vehicles and pedestrians from falling, provide physical isolation and visual guidance, etc. The retaining wall itself, as a structure for supporting the backfill soil of the roadbed or the soil mass on the hillside, plays an important role in the project. The addition of the steel guardrail further strengthens these functions, especially in the application of ensuring traffic safety.
[0003] In the actual use of the existing gravity retaining wall and the steel guardrail, the steel guardrail is usually fixedly connected to the retaining wall. When an object rolls down from the top of the retaining wall, a rolling object with a small impact force can be effectively intercepted. However, when a rolling object with a large impact force rolls down from the top of the retaining wall in case of a dangerous situation, the hard interception between the rolling object and the steel guardrail will cause the steel guardrail to be torn and thus unable to effectively intercept the rolling object. For this reason, we propose a connecting structure between a retaining wall and a steel guardrail. Content of the Utility Model

Specific embodiments
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution: a connection structure between a retaining wall and a steel guardrail, including,
[0026] A retaining wall body 1, the retaining wall body 1 is used to prevent the filling or the soil body from deforming and losing stability, a steel guardrail body 2, the steel guardrail body 2 is used to prevent objects from slipping, the steel guardrail body 2 includes steel columns 7 arranged on the top of the retaining wall body 1, there are several steel columns 7, and steel rods 21 are fixedly connected to the opposite side of the several steel columns 7.
[0027] Through the above-mentioned structure provided, it is possible to intercept an object when the object falls from the top of the retaining wall body 1. Specifically, when the object is about to roll down from the top of the retaining wall body 1, at this time, the object abuts against one side of the steel rod 21 and the steel column 7, and the object is intercepted by the steel rod 21 and the steel column 7.
[0028] Buffer mechanism 3. The buffer mechanism 3 includes a fixed block 5 fixedly connected to the top of the retaining wall 1. A buffer block 6 is fixedly connected to the top of the fixed block 5. Both sides of the inner wall of the steel column 7 are fixedly connected with a rotating shaft 8. The rotating shaft 8 is rotatably connected to the inside of the buffer block 6. A limiting rope 9 is fixedly connected to the outside of the rotating shaft 8. The bottom of the limiting rope 9 is fixedly connected to the top of the fixed block 5. Both sides of the inner wall of the steel column 7 are fixedly connected with buffer plates 11. Pressure springs 12 are fixedly connected to the bottoms of the two buffer plates 11. The bottoms of the two pressure springs 12 are fixedly connected to the top of the buffer block 6. A limiting shell 10 is fixedly sleeved on the outside of the steel column 7. The buffer block 6 is movably sleeved inside the limiting shell 10.
[0029] With the above - set structure, it can buffer and intercept rolling objects with greater impact force, improving the interception effect. Specifically, when an object is about to roll from the top of the retaining wall 1, at this time the object abuts against one side of the steel rod 21 and the steel column 7. Due to the large impact force of the rolling object, at this time the limiting shell 10 breaks and the limiting rope 9 stretches, and the steel column 7 rotates on the top of the buffer block 6. During the rotation of the steel column 7, the buffer plate 11 is driven to move, and the buffer plate 11 compresses the pressure spring 12 when it moves.
[0030] It is worth mentioning that during the rotation of the steel column 7, its anti - rotation force gradually increases, which can buffer and intercept rolling objects with greater impact force. At the same time, the set limiting shell 10 can also protect the parts inside the steel column 7, avoiding the influence of corrosion over time on the interception effect.
[0031] A strengthening mechanism 4 is fixedly connected to one side of the steel column 7. The strengthening mechanism 4 includes an anti - corrosion shell 13 fixedly connected to one side of the steel column 7. A telescopic sleeve 14 is rotatably connected to the inside of the anti - corrosion shell 13. A telescopic plate 15 is slidably connected to the inside of the telescopic sleeve 14. A rotating plate 16 is rotatably connected to the inside of the telescopic plate 15. A friction block 18 is fixedly connected to the bottom of the telescopic plate 15. A limiting block 17 is fixedly connected to one side of the inner wall of the anti - corrosion shell 13. The top of the limiting block 17 abuts against the bottom of the friction block 18. The bottom of the friction block 18 is adapted to the top of the fixed block 5.
[0032] With the above - set structure, it can provide fixed support to the steel column 7 in time when the rotation angle of the steel column 7 is too large, avoiding the rolling object from rolling over the top of the steel column 7. Specifically, when the steel guardrail body 2 abuts against a rolling object with greater impact force, at this time the steel column 7 rotates, and the rotation of the steel column 7 drives the anti - corrosion shell 13 to tilt. The tilting of the anti - corrosion shell 13 causes the bottom of the friction block 18 to separate from the top of the limiting block 17. At this time, the telescopic plate 15 slides out of the inside of the telescopic sleeve 14, and the bottom of the friction block 18 abuts against the bottom of the fixed block 5. At this time, the rotating plate 16 rotates inside the telescopic plate 15, and the top of the rotating plate 16 abuts against the bottom of the telescopic sleeve 14, preventing the telescopic plate 15 from retracting into the inside of the telescopic sleeve 14, thereby providing support to the steel column 7.
[0033] A corrosion-proof cap 19 is movably inserted at the top of the steel column 7. Anti-corrosion sleeves 22 are fixedly connected to both sides of the steel column 7. The anti-corrosion sleeves 22 are fixedly sleeved outside the steel rods 21. Anti-corrosion plates 20 are fixedly connected to both sides of the corrosion-proof cap 19.
[0034] By setting the above structure, it is possible to prevent the connection between the steel column 7 and the steel rod 21 from corroding due to long time, and indirectly improve the protection performance of the steel guardrail body 2.
[0035] Buffer steel wires 23 are fixedly connected to the opposite sides of several steel columns 7. The buffer steel wires 23 are movably connected inside the adjacent steel rods 21.
[0036] By setting the above structure, when the steel rod 21 is bent or broken, the buffer steel wire 23 can intercept the rolling object, so that the steel guardrail body 2 still has protection performance.
[0037] Working principle: Intercept the object when it falls from the top of the retaining wall body 1. Specifically, when the object is about to roll off from the top of the retaining wall body 1, at this time the object abuts against one side of the steel rod 21 and the steel column 7, and the steel rod 21 and the steel column 7 intercept the object.
[0038] When the object is about to roll off from the top of the retaining wall body 1, at this time the object abuts against one side of the steel rod 21 and the steel column 7. Due to the large impact force of the rolling object, at this time the limiting shell 10 breaks and the limiting rope 9 stretches, and the steel column 7 rotates on the top of the buffer block 6. During the rotation of the steel column 7, the buffer plate 11 is driven to move, the buffer plate 11 moves to compress the pressure spring 12, and the anti-rotation force of the steel column 7 gradually increases during the rotation process, which can buffer and intercept the rolling object with a large impact force, and avoid being affected by corrosion due to long time and affecting the interception effect.
[0039] When the steel guardrail body 2 comes into contact with a rolling object with a large impact force, at this time the steel column 7 rotates, the rotation of the steel column 7 drives the anti-corrosion shell 13 to tilt, the tilting of the anti-corrosion shell 13 causes the bottom of the friction block 18 to separate from the top of the limiting block 17, at this time the telescopic plate 15 slides out from the inside of the telescopic sleeve 14, the bottom of the friction block 18 abuts against the bottom of the fixed block 5, at this time the rotating plate 16 rotates inside the telescopic plate 15, and the top of the rotating plate 16 abuts against the bottom of the telescopic sleeve 14, preventing the telescopic plate 15 from retracting inside the telescopic sleeve 14, thereby providing support for the steel column 7.
[0040] When the steel rod 21 is bent or broken, the buffer steel wire 23 intercepts the rolling object, so that the steel guardrail body 2 still has protection performance.
