Environment-friendly sound absorption and noise reduction barrier based on municipal bridge

Abstract

The invention provides an environment-friendly sound absorption and noise reduction barrier based on a municipal bridge, relates to the technical field of noise reduction barriers, and aims at solvingproblems that when an existing bridge sound absorption and noise reduction barrier is used and encounters strong wind, thick lines are prone to loosening, an automatic auxiliary fixing structure doesnot exist after loosening, and the noise reduction barrier cannot be automatically reinforced. The barrier comprises a main body and a side groove. The main body is a plate-shaped structure, and a top end of the main body is an arc-shaped structure. The side groove is formed in the left end of the main body, and the connector at the right end of the side groove is arranged at the right end of themain body; a supporting plate is located at the rear end of the main body; a bottom piece is used for being mounted at the bottom of the main body; and the main body can be connected with a bridge guardrail through the bottom piece during mounting. And when the device is used for a long time and blown by strong wind to shake back and forth, a gap can be formed between the bottom piece and the guardrail so that a fixing piece is not fixed with the guardrail, is in contact with a limiting position, and downwards moves and extends under the action of a 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
