Description

Technical Field

[0001] The utility model relates to the technical field of highway sound barriers, in particular to a sound barrier structure for highways in hot and humid rainy areas. Background Art

[0002] A sound barrier is a specially designed acoustic barrier placed between a noise source and a receiving point. It is primarily used to isolate and reduce noise from highways, expressways, elevated roads, and other noise sources. With the continuous increase in expressway coverage, mileage, and traffic volume, the traffic noise generated by these barriers is seriously impacting the daily lives of residents along these routes. Therefore, it is necessary to install sound barriers on both sides of expressways to achieve noise reduction.

[0003] The structure of a highway sound barrier primarily consists of a foundation, columns, and sound-absorbing panels (or barrier panels). The foundation is the foundation of the sound barrier and is typically made of concrete or other solid materials to ensure the stability and wind resistance of the entire structure. The columns, the primary components supporting the sound barrier panels, are typically made of steel and treated with corrosion protection to extend their service life. The columns are embedded in the foundation to ensure sufficient strength. The sound-absorbing panels are the main component of the sound barrier, primarily providing sound insulation and noise reduction. The panels are connected to the columns at both ends.

[0004] Combined sound barriers are a new type of sound barrier structure that can improve construction efficiency and reduce manufacturing and transportation costs. Typically, combined sound barriers feature protrusions on both ends of the sound-absorbing panels, which are then slotted into corresponding columns. Assembly is achieved through the interlocking of the protrusions and the insertion of these protrusions. This installation method not only facilitates installation and replacement, but also avoids the rainwater corrosion and rusting problems associated with traditional bolts, nuts, and other fasteners. However, in practice, combined sound barriers have been found to be susceptible to rainwater seeping into the panels, causing a rapid decrease in sound absorption. This is particularly true in hot, humid, and rainy regions like Guangdong Province, where panels require frequent replacement. Utility Model Content

[0005] The main purpose of the utility model is to provide a sound barrier structure for highways in hot and humid rainy areas, so as to solve the technical problem of rainwater seeping into the interior of the sound-absorbing board in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a sound barrier structure for highways in hot and humid rainy areas, and the technical solution is as follows:

[0007] The sound barrier structure for highways in hot and humid rainy areas includes columns and sound absorbing components, wherein the sound absorbing components have multiple sound absorbing units distributed from top to bottom, and an elastic sealing layer is provided between two adjacent sound absorbing units; the columns have vertical slots adapted to the sound absorbing components; the sound barrier structure also includes a top fixing component, wherein the top fixing component includes a top plate and a top cover, wherein both ends of the top plate are adapted to the vertical slots, the top cover is adapted to the top of the columns, and the top cover is detachably connected to the top plate.

[0008] In the present invention's sound barrier structure for highways in hot, humid, and rainy areas, the dual protection provided by the elastic sealing layer and the top fixing assembly effectively prevents rainwater from seeping into the sound-absorbing material within the sound-absorbing unit, effectively extending the service life of the sound-absorbing material. This demonstrates the present invention's simple structure, low manufacturing costs, ease of assembly and disassembly, excellent sound absorption, and long service life. It addresses the prior art issue of rainwater seeping into the interior of the sound-absorbing panels, demonstrating its high practicality.

[0009] As a further improvement to the aforementioned sound barrier structure for highways in hot, humid, and rainy regions, the top cover is provided with a flange on the side in contact with the top plate. The flange is provided with a through-hole, and the top plate is provided with a threaded rod that fits within the through-hole. The threaded rod passes through the through-hole and is secured with a nut. This results in a simple, stable structure and easy assembly and disassembly.

[0010] As a further improvement to the aforementioned sound barrier structure for highways in hot, humid, and rainy regions, the top fixing assembly also includes an elastic body positioned between the top of the column and the top cover. This allows for height variations in the sound-absorbing units due to machining accuracy, improving coordination among the column, sound-absorbing assembly, and top fixing assembly.

[0011] As a further improvement to the above-mentioned sound barrier structure for highways in hot and humid rainy areas: the elastomer is a sponge layer arranged according to the gap height; or, the elastomer is a spring.

[0012] As a further improvement to the aforementioned sound barrier structure for highways in hot, humid, and rainy regions, the sound barrier structure further includes a bottom fixing assembly comprising a base plate and a bolt mechanism, the bolt mechanism being anchored to the ground foundation. The base plate is welded to the inner and outer sides of the columns, and the base plate is provided with through holes adapted for the bolt mechanisms. This allows the columns to be quickly and securely installed on the ground foundation, which is preferably, but not limited to, concrete.

[0013] As a further improvement to the aforementioned sound barrier structure for highways in hot, humid, and rainy regions, the bottom fixing assembly also includes a base plate and a connecting plate. The base plate's ends fit into the vertical slots, and the connecting plate spans the base plate and the base plate. Both the base plate and the connecting plate are provided with through-holes compatible with the bolt mechanism. This improves the connection strength between the sound barrier structure and the ground foundation, thereby enhancing the sound barrier structure's impact resistance.

[0014] As a further improvement to the aforementioned sound barrier structure for highways in hot, humid, and rainy areas, an elastic sealing layer is also provided between the top plate and the sound-absorbing unit and / or between the bottom plate and the sound-absorbing unit; the elastic sealing layer is a rubber layer, thereby further enhancing the water-proofing effect.
