An environmentally friendly sound-absorbing and noise-reducing barrier based on municipal bridges

Abstract

The invention provides an environmental-friendly sound-absorbing and noise-reducing barrier based on a municipal bridge, which relates to the technical field of noise-reducing barriers and solves the problem that existing bridge sound-absorbing and noise-reducing barriers tend to have thick lines when they encounter strong winds when they are in use. Loose, and after loosening, there is no automatic auxiliary fixing structure, and the noise reduction barrier cannot be automatically reinforced, including the main body and side slots; the main body is a plate-shaped structure, and the top of the main body is an arc-shaped structure; the side slots It is arranged at the left end of the main body, and the connecting head at the right end of the side groove is arranged at the right end of the main body; the support plate is at the rear end of the main body. The bottom part is used to be installed on the bottom of the main body, so that the main body can be connected with the bridge guardrail through the bottom part when the main body is installed. There will be a gap between them, so that the fixing part is released from being fixed with the guardrail, and the fixing part touches the limit, so as to move and extend downward by gravity.

Description

technical field [0001] The invention belongs to the technical field of noise-reducing barriers, and more specifically relates to an environmental-friendly sound-absorbing and noise-reducing barrier based on municipal bridges. Background technique [0002] Sound insulation walls, also known as sound barriers, are mainly used for sound insulation and noise reduction of roads, expressways, elevated composite roads and other noise sources. [0003] For example, the application number: CN201710623890.5 relates to a metal sound barrier for bridges, including aluminum foam panels and back panels, and galvanized steel sheets on four sides. The galvanized steel sheet is pressed into a U-shaped profile, and the aluminum foam panel and back panel are fixedly connected with the galvanized steel sheet to form a metal sound barrier with a cavity structure. Due to the curved structure of the front, it has higher structural strength compared with the sound barrier of the same width; with a...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an environmentally friendly sound-absorbing and noise-reducing barrier based on municipal bridges, so as to solve the problem that the existing bridge sound-absorbing and noise-reducing barriers are easy to loose when encountering strong winds. , and after loosening, there is no automatic auxiliary fixing structure, and the noise reduction barrier cannot be automatically reinforced, and the existing bridge sound-absorbing noise-reduction barrier cannot be conveniently added or replaced with wood chips, and the noise cannot pass through the wood chips. The problem of rebounding again for sound absorption again
