Description

Technical Field

[0001] The present application relates to the technical field of highway protection facilities, and in particular to a sound barrier integrated guardrail. Background Art

[0002] The sections of highways that pass through residential areas need to be equipped with sound barriers to reduce noise. Sound barriers can only block sounds, but cannot resist the impact of out-of-control vehicles. A separate anti-collision guardrail is also required in front of the sound barrier to resist the impact of vehicles. In order to prevent out-of-control vehicles from hitting the sound barrier columns and causing them to trip, the sound barrier should be installed outside the maximum deformation range of the guardrail. This requires increasing the lateral width of the highway. If the sound barrier is installed on the slope, it will make construction more difficult and will also increase construction costs. In addition, the sound barrier and the guardrail are set separately, and the sound barrier and the guardrail need to be constructed separately, and the construction quality is not easy to control.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. However, the example implementation can be implemented in various forms and should not be construed as being limited to the implementations set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all illustrated by taking the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0022] It should be noted that specific details are described in the following description to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the embodiments of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0023] First, let's introduce the application scenario. A sound barrier is a facility set between the sound source and the receiver to make the sound wave have a significant additional attenuation, thereby reducing the noise impact of a certain area where the receiver is located. When the sound wave encounters a sound barrier during propagation, three phenomena will occur: reflection, transmission and diffraction. The sound barrier can prevent the propagation of direct noise and sufficiently attenuate the bypass noise. When a barrier is inserted between the sound source and the receiving point, the sound wave can only diffract over the barrier, and a sound shadow area is formed behind it, and people can feel that the noise is significantly reduced. The height of the sound barrier is usually more than three meters to achieve the effect of noise reduction. The sound absorbing board of the sound barrier has low strength and cannot be used as an anti-collision guardrail on the road. Usually, a guardrail is set on the inside of the sound barrier. In order to prevent the deformation of the guardrail from affecting the sound barrier, there is also a certain interval between the guardrail and the sound barrier, which will take up a large space, and the lateral width of the highway needs to be increased, which increases the construction cost.

[0024] In view of this, an embodiment of the present application provides a sound barrier integrated guardrail to solve the problem in the prior art that the sound barrier and guardrail are separately set up, which occupies a large space and has high construction costs.

[0025] Figure 1 This is a schematic diagram of the structure of a sound barrier guardrail provided in an embodiment of the present application. Figure 2 A side view of a sound barrier guardrail provided in one embodiment of the present application, Figure 3 A top view of a sound barrier guardrail provided in one embodiment of the present application, Figure 4 This is a three-dimensional diagram of a sound barrier guardrail provided in one embodiment of the present application. Figure 1 to Figure 4In one embodiment, the sound barrier integrated guardrail includes a sound absorbing panel 1, a plurality of columns 2 and a first protective beam 3. The plurality of columns 2 are installed on the road surface and are arranged at intervals along the extension direction of the road, and the sound absorbing panel 1 is installed between two adjacent columns 2. The sound absorbing panel 1 is used to absorb the noise generated when a vehicle passes by. The columns 2 include a first column 21 and a second column 22, the first column 21 is connected to the road surface, the second column 22 is installed at one end of the first column 21 away from the road surface, and the first protective beam 3 is installed on the side of the first column 21 facing the road.

[0026] In the above embodiment, the sound absorbing board 1 is installed on the column 2 of the guardrail, so that the sound barrier and the guardrail are integrated, occupying less space, and no additional construction is required to widen the road to install the sound barrier. In addition, the column 2 adopts a segmented design. The first protective beam 3 is installed on the first column 21 located below. After the guardrail is deformed by impact, usually only the first column 21 located below is damaged. Only the first column 21 needs to be replaced, and the second column 22 located above can continue to be used, saving costs.

[0027] In one embodiment, the length a of the first column 21 and the length b of the second column 22 satisfy a<b. The weight of the car is mainly concentrated in the chassis, and the vehicle needs sufficient angular momentum to roll over the guardrail. Therefore, in general, as long as the height of the guardrail can stop the wheels, it can play a protective role. The center of the first protective beam 3 is 60cm to 70cm away from the road surface, and the total height of the column is 300cm to 310cm. The length of the first column 21 is shorter than that of the second column 22, which can not only play a protective role, but also save materials when it is replaced due to damage.

[0028] The material of the column 2 can be carbon steel, cast iron, cast aluminum, aluminum alloy, stainless steel, etc.

[0029] In one embodiment, the first protection beam 3 is a corrugated plate. The corrugated plate may be a three-wave plate. Along the extension direction of the road, a plurality of corrugated plates overlap each other to form the first protection beam 3. Double rows of screws may be provided at the overlapped position for fixing. The plane where each row of screws is located is perpendicular to the road surface.

[0030] In one embodiment, in order to increase the strength of the guardrail, a first buffer block 5 is provided between the first protection beam 3 and the first column 21. The first buffer block 5 is a hollow structure, and its cross section can be square, trapezoidal or hexagonal. The axis of the first buffer block 5 is parallel to the road surface.

[0031] In order to improve the protection effect, the above-mentioned integrated sound barrier guardrail also includes a second protection beam 4, which is installed on the side of the first column 21 facing the road, and the second protection beam 4 is located on the side of the first protection beam 3 away from the road surface. The installation height of the second protection beam 4 is higher than the first protection beam 3, which can improve the protection effect of the guardrail and protect the sound absorbing board 1 from impact.

[0032] The second protection beam 4 may be a hollow structure, and its cross section may be square, rectangular or C-shaped. Its material may be carbon steel, cast iron, cast aluminum, aluminum alloy, stainless steel or the like.

[0033] In other specific implementations, the second protection beam 4 may also be a channel steel, an I-beam or an H-beam.

[0034] In one embodiment, the second protection beam 4 comprises a top wall, and the top wall and the joint between the first column 21 and the second column 22 are in the same horizontal plane.

[0035] In one embodiment, a second buffer block 6 is provided between the second protection beam 4 and the first column 21. The structure of the second buffer block 6 can be the same as that of the first buffer block 5, which is a hollow structure, and its cross section can be square, trapezoidal or hexagonal. The axis of the second buffer block 6 is parallel to the road surface.

[0036] In one embodiment, the above-mentioned sound barrier integrated guardrail further includes a mounting flange 7 and a plurality of stiffening ribs 8, and the mounting flange 7 is used to fix the first column 21 to the road surface. Specifically, the above-mentioned first column 21 is fixedly mounted on the mounting flange 7. In order to improve the firmness of the first column 21 and the mounting flange 7, two stiffening ribs 8 are also provided. The stiffening rib 8 is connected to the first column 21 and the mounting flange 7, and the stiffening rib 8 is located on the circumferential side of the first column 21, one of the stiffening ribs 8 is provided on the side of the first column 21 facing the road, and the other stiffening rib 8 is provided on the side of the first column 21 away from the road.

[0037] In one embodiment, the column 2 may be an I-beam or an H-beam. The column 2 has a groove 20, and the end of the sound absorbing board 1 is installed in the groove 20. Specifically, each of the columns 2 has two grooves 20 that are separated from each other, and the grooves 20 of two adjacent columns 2 are arranged oppositely, and the end of the sound absorbing board 1 is embedded in the groove 20, so as to facilitate its fixation to the column 2.

[0038] In a specific embodiment, the first column 21 and the second column 22 are both H-shaped steel. The first column 21 and the second column 22 can be fixed by a clamp. Specifically, the first column 21 includes a first plate 211 and a second plate 212, which are arranged opposite to each other and are parallel to the extension direction of the road and perpendicular to the road surface. The second column 22 includes a third plate 221 and a fourth plate 222, which are arranged opposite to each other and are parallel to the extension direction of the road and perpendicular to the road surface. When the first column 21 and the second column 22 are spliced, the first plate 211 and the third plate 221 are butt-jointed, and the second plate 212 and the fourth plate 222 are butt-jointed. The clamp includes a first clamp 9 and a second clamp 10, which are respectively arranged on both sides of the second plate 212 and the fourth plate 222, and cover the joint between the second plate 212 and the fourth plate 222. Finally, screws are used to pass through the first clamping plate 9, the second plate body 212 and the second clamping plate 10 in sequence to fix them, and screws are used to pass through the first clamping plate 9, the fourth plate body 222 and the second clamping plate 10 in sequence to fix them, so that the first column 21 and the second column are fixed together.

[0039] The sound absorbing panel 1 can be fixed to the second plate body 212 and the fourth plate body 222 , or to the first plate body 211 and the third plate body 221 by screws.

[0040] It is worth noting that the above-mentioned column 2 can also be in other shapes, such as square tube, rectangular tube, C-shaped steel, channel steel, I-shaped steel, etc. Its material is not limited to carbon steel, and can also be cast iron, cast aluminum, aluminum alloy, stainless steel, etc.

[0041] There are multiple sound-absorbing panels 1, and multiple sound-absorbing panels 1 are sequentially arranged between two adjacent columns 2 in a direction perpendicular to the road surface to form a sound-absorbing wall. The area where the sound-absorbing panels 1 are laid occupies the space between two adjacent columns 2, that is, the height of the sound-absorbing wall is equal to the length of the column 2, which improves the sound absorption effect of the integrated sound barrier guardrail. The sound-absorbing panels 1 can specifically be louver-type sound-absorbing panels 1, which have multiple sound-absorbing holes to improve the sound absorption effect.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
