在公路、办公室或是不同的建筑物内，我们都可以看到隔音屏障的存在。隔音屏障主要是为了减少交通噪声的污染而生成的，隔音屏障是一种建立在声源以及接受者之间的遮挡建筑物。它最主要的作用就是帮助直达声直接的传播，简单来说，隔音屏障就是一个隔声设施。

We can see sound insulation barriers on roads, in offices, or in different buildings.Acoustic barriers are mainly generated to reduce pollution from traffic noise, a blocking building built on sound sources and between recipients.Its main role is to help the direct transmission of sound, simply put, sound barrier is a sound insulation facility.

阻性隔音屏障由前板，后板，侧板构成一个封闭的箱式结构，形成一个模块化单元。前板为穿孔率为穿孔率25%的镀锌钢板，后板和侧板为不穿孔的镀锌钢板，（从美观角度考虑，也可用彩色钢板）。两层板之间内填防潮离心玻璃棉板，吸声材料用聚氟乙烯薄膜覆盖。立柱为12#工字钢，柱间距2m。立柱插于钢筋混凝土的基础内。

The resistance barrier consists of the front, rear, and side panels forming a closed box structure, forming a modular unit.The front plate is galvanized steel plate with 25% perforation rate, and the rear plate and side plate are non-perforated galvanized steel plate (also color plate).The two layers are filled with moisture-proof centrifugal glass cotton board, and the sound absorption material is covered with polyvinyl fluoride film.The column is 12 # I-word steel, with a column spacing of 2m.The column is inserted into the reinforced concrete foundation.

热镀锌是一种有效的金属防腐方式，主要用于各行业的金属结构设施上。是将除锈后的钢件浸入500℃左右融化的锌液中，使钢构件表面附着锌层，从而起到防腐的目的。镀锌层比较牢固。

Thermal galvanizing is an effective metal anticorrosion method, mainly used in metal structure facilities in various industries.It is to rust the steel parts into about 500℃ of melted zinc liquid, so that the steel members surface attached zinc layer, so as to play the purpose of corrosion.The galvanized layer is relatively firm.
