Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sound barrier technology, specifically relating to an obstacle avoidance and warning structure for a fully enclosed sound barrier. Background Technology
[0002] As urban construction continues to expand, urban transportation is also developing rapidly. Due to increasingly scarce land resources, urban rail transit and elevated bridges are being promoted more and more. Because urban light rail is very close to residential areas, noise pollution has become a primary issue to address.
[0003] Fully enclosed sound barriers can reduce noise within a very limited distance from the sound source, thus significantly reducing noise pollution. Installing fully enclosed barriers near residential areas, compared to relocating the area and replanning roads, has higher construction costs, shorter construction periods, and better socio-economic benefits, while also achieving more rational and optimal use of land resources.
[0004] During use, fully enclosed sound barriers inevitably cause passing vehicles to scrape against the pillars because the fully enclosed frame completely covers the entire structure. This is especially true for vans, whose cargo box is significantly wider than the vehicle body, making it difficult for drivers to judge the distance between themselves and the sound barrier pillars. This increases the likelihood of collisions between the cargo box and the main pillars of the enclosed sound barrier at the top of the barrier, posing a safety hazard to the overall safety performance of the enclosed sound barrier. Utility Model Content
[0005] The purpose of this utility model is to provide an obstacle avoidance and warning structure for a fully enclosed sound barrier. By setting an obstacle avoidance plate facing the inside of the column, the column is protected. After the vehicle body scrapes against the obstacle avoidance plate, an audible warning is issued to the driver to maintain a distance from the column, thereby improving the safety of the fully enclosed sound barrier.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fully enclosed sound barrier obstacle avoidance and warning structure includes a sound barrier frame composed of two side columns and beams. The structure is characterized in that: the lower end of each column is connected to the upper end of a roadside platform or retaining wall; each column has a bent section extending outwards from the road; a plurality of upright obstacle avoidance plates are arranged on the inner side of the bent section; each obstacle avoidance plate is a wear-resistant rubber sheet with built-in elastic steel fibers or elastic metal sheets; the root of each obstacle avoidance plate is installed on the inner side of the column via a connector, or the root of each obstacle avoidance plate is directly connected to the inner side of the column by welding, bonding, or bolting.
[0007] Additional technical features constituting the obstacle avoidance and warning structure of the aforementioned fully enclosed sound barrier also include: —The connector includes a pressure plate with a central perforation, the pressure plate is connected to the inner side of the column by several bolts, a base plate is provided at the root of the obstacle avoidance plate, the end of the obstacle avoidance plate passes through the perforation, and the base plate is placed between the pressure plate and the inner side of the column; —The column is made of H-beams, the obstacle avoidance plate is installed on the side plate surface of the H-beams, the bottom of the column is provided with a fixing plate, and the four corners of the fixing plate are provided with anchor bolts or connected to pre-embedded anchors. —Reflective warning strips are provided on the surface of the columns, the obstacle avoidance plates, and / or the surface of the beams and columns.
[0008] Compared with the prior art, the obstacle avoidance warning structure of the fully enclosed sound barrier provided by this utility model has the following advantages: The obstacle avoidance warning structure includes an obstacle avoidance plate set inside the sound barrier column. The obstacle avoidance plate is located on the curved section of the column extending outward toward the road, with its end facing inward. When a vehicle approaches the column (barrier wall), the obstacle avoidance plate scrapes against the vehicle body, and the sound can effectively warn the driver to maintain a safe distance, avoiding direct collision between the vehicle body and the column, thus enhancing the safety and stability of the sound barrier. Secondly, the obstacle avoidance plate is a wear-resistant rubber plate with built-in elastic steel fibers or elastic metal sheets. This composite structure has high mechanical strength, wear resistance, scratch resistance, and a long service life. It has the advantages of simple structure, convenient use, safety, and durability. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of an obstacle avoidance and warning structure for a fully enclosed sound barrier according to the present invention; Figure 2 This is a partial schematic diagram of the obstacle avoidance and warning structure. Detailed Implementation
[0010] The obstacle avoidance and warning structure and working principle of the fully enclosed sound barrier provided by this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0011] In the description of this utility model, unless otherwise stated, the terms "inner / outer", "upper / lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0012] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "set / equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0013] like Figure 1 As shown, the obstacle avoidance warning structure of the fully enclosed sound barrier includes a sound barrier frame composed of two side columns 1 and beam columns 2. The lower end of the column 1 is connected to the base of the road bridge a or the upper end of the retaining wall b. The column 1 has a bent section 11 extending outward from the road. Several obstacle avoidance plates 3 are arranged standing on the inner side of the bent section 11. The obstacle avoidance plates 3 are wear-resistant rubber plates with built-in elastic steel fibers or elastic metal sheets. The root of the obstacle avoidance plate 3 is installed on the inner side of the column 1 through a connector, or the root of the obstacle avoidance plate 3 is directly connected to the inner side of the column 1 by welding, bonding or bolting.
[0014] Its working principle is as follows: The frame of the fully enclosed sound barrier is composed of columns 1 and beams 2. The obstacle avoidance plate 3 is installed on the inner side of the column 1, that is, the curved section 11 that extends outward from the road. This area is the extension of the road and bridge space and is also the place where it is difficult for the driver to judge the distance between the vehicle and the vehicle. When the vehicle approaches the barrier wall b (column 1), it first scrapes against the end of the obstacle avoidance plate 3, and the sound reminds the driver to keep the distance and avoid further collision with the column 1. After the vehicle moves away, the obstacle avoidance plate 3 returns to the standing position and continues to play the obstacle avoidance warning effect.
[0015] To improve the lifespan of the obstacle avoidance plate 3, it is made of wear-resistant rubber plate with built-in elastic steel fibers or elastic metal sheets. It has high mechanical strength, good elasticity and toughness, strong self-healing ability, and can maintain its standing position after repeated pressing. This elastic structure is economical and durable.
[0016] In the obstacle avoidance and warning structure that constitutes the aforementioned fully enclosed sound barrier --like Figure 2 As shown, in a preferred embodiment, the connecting member includes a pressure plate 41 with a through hole 40 in the center. The pressure plate 41 is connected to the inner side of the column 1 by several bolts 42. A base plate 31 is provided at the root of the obstacle avoidance plate 3. The end of the obstacle avoidance plate 3 passes through the through hole 40. The base plate 31 is placed between the pressure plate 41 and the inner side of the column 1. Through the above-mentioned pressing and positioning connection structure, the stability of the obstacle avoidance plate 3 is improved. During use, the obstacle avoidance plate 3 will not fall off or break when it is scratched by the vehicle body and repeatedly moves, thus further extending the working cycle. — Preferably, the column 1 is made of H-beams, the obstacle avoidance plate 3 is installed on the side plate surface of the H-beams, the bottom of the column 1 is provided with a fixing plate 12, and the four corners of the fixing plate 12 are provided with anchor bolts 42'. The H-shaped cross section of the column 1 can provide effective positioning for the installation of the obstacle avoidance plate 3, and its cross section provides convenience for the lower end anchoring, resulting in better overall structural strength. —Furthermore, reflective warning strips 5 are provided on the surface of the aforementioned pillar 1, the obstacle avoidance plate 3 and / or the beam column 2 to enhance the warning effect on the driver through light, effectively reminding the driver to maintain a safe distance from the sound barrier pillar 1 (barrier wall).
[0017] The above-described embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the implementation of this utility model. Therefore, any other modifications or equivalent substitutions to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
