Description

Technical Field

[0001] The present application relates to the technical field of highway sound insulation, and more specifically, to a highway sound insulation board device. Background Art

[0002] Highway sound insulation panels are a type of structural material designed specifically to reduce traffic noise and are usually installed along highways. These panels use sound absorption, reflection or isolation technology to effectively reduce the transmission of traffic noise such as vehicle driving and engine noise. Highway sound insulation panels usually have sound-absorbing materials on the surface, which can absorb and reduce sound waves, thereby improving the quality of life of surrounding residents and the environment. In addition, these panels are also weather-resistant and durable, and can be used for a long time in different climate conditions. They are an important environmental protection measure in urban transportation infrastructure.

[0003] The document with prior art publication number CN 204510042U provides a highway sound insulation board, which is divided into two parts by an empty layer to form a double barrier. The sound wave first impacts the rock wool layer and the cloth layer, and is absorbed by the rock wool layer and the cloth layer, and its intensity is greatly reduced to only 30% of the original intensity. The propagation of sound waves between solids or gases will be greatly lost. Therefore, after passing through the empty layer, and then passing through the plant fiber layer and the glass wool layer, the sound wave will be greatly absorbed to achieve the effect of sound insulation and sound absorption.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the above-mentioned highway sound insulation board device is an integrated structure. When it is damaged, the staff needs to replace the entire sound insulation board, which is troublesome and wastes the sound insulation board material.

When it is damaged, the staff needs to replace the entire sound insulation board, which is not only troublesome but also wastes the sound insulation board materials.

[0006] In view of this, we propose a highway sound insulation board device. Utility Model Content
