在公路、辦公室或是不同的建筑物內(nèi)，我們都可以看到隔音屏障的存在。隔音屏障主要是為了減少交通噪聲的污染而生成的，隔音屏障是一種建立在聲源以及接受者之間的遮擋建筑物。它最主要的作用就是幫助直達(dá)聲直接的傳播，簡(jiǎn)單來說，隔音屏障就是一個(gè)隔聲設(shè)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，側(cè)板構(gòu)成一個(gè)封閉的箱式結(jié)構(gòu)，形成一個(gè)模塊化單元。前板為穿孔率為穿孔率25%的鍍鋅鋼板，后板和側(cè)板為不穿孔的鍍鋅鋼板，（從美觀角度考慮，也可用彩色鋼板）。兩層板之間內(nèi)填防潮離心玻璃棉板，吸聲材料用聚氟乙烯薄膜覆蓋。立柱為12#工字鋼，柱間距2m。立柱插于鋼筋混凝土的基礎(chǔ)內(nèi)。

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.

熱鍍鋅是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結(jié)構(gòu)設(shè)施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中，使鋼構(gòu)件表面附著鋅層，從而起到防腐的目的。鍍鋅層比較牢固。

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.
