Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0026] This example provides a closed-structure elevated sound insulation system for elevated roads, which is used for sound insulation of elevated road noise.

[0027] The elevated sound insulation system uses ETFE (ethylene-tetrafluoroethylene copolymer) air pillows as sound insulation elements. The ETFE film material has good sound insulation and sound absorption capabilities, and the ETFE air pillow composed of it has multiple layers of ETFE films, and the interior is filled with air to form an air pillow, which will have good sound insulation and sound absorption capabilities.

[0028] Optionally, the ETFE air pillow can be in the form of a double-layer or multi-layer air pillow. The double-layer ETFE air pillow has two layers of ETFE films...

Abstract

The invention discloses a noise insulation system for roads. The noise insulation system for the roads is an ETFE film air pillow system which takes an ETFE air pillow as a noise insulation element and is supported by a framework. According to the noise insulation system for the roads, the noise insulation quality is improved, and the influences on surrounding residential areas and office areas of traffic noise on the roads can be relieved.

Description

technical field [0001] The invention relates to a sound insulation technology, in particular to a road traffic noise sound insulation technology. Background technique [0002] In recent years, the process of urbanization in various parts of China has been continuously improved, the urban infrastructure has been continuously improved, and the main traffic lines have been developed rapidly; people's living standards have been continuously improved, and the number of urban motor vehicles has also continued to increase. The establishment of traffic arteries such as elevated roads has greatly improved the city's traffic capacity and reduced traffic jams, but it has brought new environmental problems. The commercial buildings or residences on both sides of the elevated road are often affected by the noise made by the coming and going vehicles, which affect their normal work and the normal life of residents. The impact of urban traffic noise on the environment has become increasin...
