Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, specifically a retaining wall for preventing rockfalls on highways. Background Technology

[0002] Rockfalls have become a major threat to traffic safety. Rocks fall down the mountainside under the influence of gravity and hit the highway surface, posing a serious threat to vehicles and potentially causing personal injury and property damage. Rockfall barriers are mainly made of reinforced concrete and are designed to intercept or mitigate the impact of falling rocks.

[0003] The impact force of rolling rocks is often very large, especially on steep slopes or in areas with high elevation differences. The speed and kinetic energy of the rolling rocks increase significantly, causing the retaining wall material to gradually fatigue after being hit, resulting in cracks, deformation, or even collapse. Since existing retaining walls lack buffer mechanisms, they are more likely to be damaged by rolling rocks, which greatly reduces the service life of the retaining walls. Utility Model Content

[0004] The purpose of this utility model is to provide a retaining wall for preventing rockfalls on highways, in order to solve the problem mentioned in the background art that the existing retaining walls lack a buffer mechanism, and the retaining walls are more likely to be damaged after being directly hit by falling rocks, which greatly reduces the service life of the retaining walls.

[0007] Preferably, the angle steel is L-shaped, the fixing screw penetrates the angle steel and is screwed into the surface of the wall, and multiple sets of limiting rods are provided, which are arranged linearly and evenly on the surface of the angle steel.

[0008] Preferably, the limiting rod is in the shape of a "D", and a guide hole is provided on the surface of the angle steel, and the guide hole of the angle steel is in the shape of a "D". The limiting rod passes through the guide groove of the angle steel. Multiple sets of waste tires are provided, and multiple sets of waste tires are stacked and sleeved on the surface of the limiting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This retaining wall uses fixing screws to fix two sets of angle steel to both sides of the wall. Multiple sets of waste tires are stacked on the surface of the wall, so that the limiting rods pass through the guide holes of the angle steel and the multiple sets of waste tires are fitted onto the surface of the limiting rods.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A retaining wall for preventing rockfalls on highway slopes includes a wall body 1. Anchor rods 11 are fixedly connected to the surface of the wall body 1, and a reinforcing plate 12 is fixedly connected to the back of the wall body 1. The anchor rods 11 secure the wall body 1 to the ground, while the reinforcing plate 12 strengthens the overall structure of the wall body 1 on the ground. A short section of concrete support is provided at the bottom of the wall body 1 on the side away from the reinforcing plate 12. A buffer mechanism, including angle steel 2, is provided on the surface of the wall body 1. The angle steel 2 is in contact with the surface of the wall body 1. A fixing screw 21 is connected to the upper through hole. A limit rod 22 is connected to the surface of the angle steel 2 through a through hole. A waste tire 23 is sleeved on the surface of the limit rod 22. A fixing steel plate 24 is fixedly connected to the surface of the angle steel 2. A positioning rod 25 is connected to the surface of the fixing steel plate 24 through a through hole. A limit bolt 26 is threaded to the bottom of the positioning rod 25. This buffer mechanism uses multiple sets of waste tires 23 to buffer the impact of rolling stones, thereby greatly reducing the probability of damage to the wall 1 from rolling stones and extending the service life of the wall 1.

[0025] Furthermore, a flow guiding mechanism is provided at the bottom of the wall 1. The flow guiding mechanism includes a drain hole 3, which is located at the bottom of the wall 1. A filter plate 31 is fixedly installed on the drain hole 3. A drain trough 32 is fixedly connected to the bottom of the wall 1. A buffer plate 33 is fixedly connected to the surface of the drain trough 32. A support plate 34 is fixedly connected to the surface of the drain trough 32. The flow guiding mechanism guides the water source into the drain trough 32 through the drain hole 3, and then discharges the water source through the drain trough 32, preventing the water source from flowing to the roadbed and ensuring the safety of the roadbed. In addition, a buffer plate 33 is set inside the drain trough 32 for buffering, which extends the service life of the drain trough 32.

[0026] Furthermore, the angle steel 2 is in the shape of an "L" and the fixing screw 21 penetrates the angle steel 2 and is screwed into the surface of the wall 1. There are multiple sets of fixing screws 21, which fix the angle steel 2 on the surface of the wall 1. There are multiple sets of limiting rods 22, which are arranged linearly and evenly on the surface of the angle steel 2. The waste tires 23 are arranged in a matrix on the surface of the wall 1.

[0027] Furthermore, the limiting rod 22 is in the shape of a "D", and a guide hole is opened on the surface of the angle steel 2. The guide hole of the angle steel 2 is also in the shape of a "D". The limiting rod 22 passes through the guide groove of the angle steel 2. Multiple sets of waste tires 23 are provided, and multiple sets of waste tires 23 are stacked and sleeved on the surface of the limiting rod 22. One side of the waste tires 23 is in contact with the surface of the wall 1. The limiting rod 22 restricts the position of multiple sets of waste tires 23 on the surface of the wall 1, so that multiple sets of waste tires 23 can be located on the surface of the wall 1 to buffer the impact of rolling stones.

[0028] Furthermore, the fixed steel plate 24 is provided with two sets of limiting rods 22, which pass through both sets of fixed steel plates 24 simultaneously. Limiting holes are opened on the surface of the limiting rods 22, and positioning rods 25 pass through the limiting holes of multiple sets of limiting rods 22 simultaneously. Since the limiting rods 22 are in the shape of a "D", the limiting rods 22 restrict the orientation of the limiting holes on the angle steel 2. The bottom of the positioning rod 25 is provided with a threaded groove, and the limiting bolt 26 is threadedly connected to the threaded groove of the positioning rod 25. Since one end of the positioning rod 25 is a limiting plate, it cannot pass through the fixed steel plate 24, so that the limiting bolt 26 can fix the positioning rod 25 on the surface of the fixed steel plate 24, while the fixed steel plate 24 restricts the position of multiple sets of limiting rods 22 on the angle steel 2.

[0029] Furthermore, multiple sets of drainage holes 3 are provided, and the drainage holes 3 are at an inclined angle. The drainage holes 3 and the buffer plate 33 are perpendicular to each other, so that the drainage holes 3 can directly lead the water source onto the surface of the buffer plate 33, while the filter plate 31 can filter the water source of the angle steel 2 to avoid clogging.

[0030] Furthermore, the end of the support plate 34 away from the drainage channel 32 is fixedly connected to the surface of the buffer plate 33. The support plate 34 and the buffer plate 33 are perpendicular to each other. Both the buffer plate 33 and the support plate 34 are inclined inside the drainage channel 32. The support plate 34 strengthens the structural strength of the buffer plate 33 inside the drainage channel 32. Multiple sets of through holes are opened on the surface of the buffer plate 33. Water flows through the through holes to the other side of the buffer plate 33, ensuring that the actual flow rate of the drainage channel 32 is not affected.

[0031] Working principle: Two sets of angle steel 2 are fixedly installed on both sides of the wall 1 by fixing screws 21. Multiple sets of waste tires 23 are stacked on the surface of the wall 1, so that the limiting rod 22 passes through the guide hole of the angle steel 2 and the multiple sets of waste tires 23 are sleeved on the surface of the limiting rod 22. At this time, the positioning rod 25 passes through the limiting hole of the fixing steel plate 24 and the limiting rod 22, and the limiting bolt 26 is threaded to the bottom of the positioning rod 25. The positioning rod 25 restricts the position of the multiple sets of limiting rods 22, and the multiple sets of limiting rods 22 restrict the multiple sets of waste tires 23 on the surface of the wall 1. The waste tires 23 cushion the rolling stones on the surface of the wall 1, thereby reducing the probability of the wall 1 being damaged by the rolling stones, and thus extending the service life of the wall 1.

[0032] The wall 1 directs water to the drainage channel 32 through the drainage hole 3, and filters the water through the filter plate 31. The drainage channel 32 can discharge the water in a unified manner, avoiding the water from impacting the roadbed and thus ensuring the safety of the roadbed. In addition, the support plate 34 inside the drainage channel 32 strengthens the structural strength of the buffer plate 33. The buffer plate 33 inside the drainage channel 32 buffers the water released from the drainage hole 3, thereby extending the service life of the drainage channel 32 on one side of the wall 1.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
