　　通風管道是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。通風管，風管制作與安裝所用板材、型材以及其他主要成品材料，應符合設計及相關產(chǎn)品標準的規(guī)定，并應用出廠檢驗合格證明，材料進場時應按有關標準進行驗收。

Ventilation ducts are a type of municipal infrastructure designed to facilitate air circulation and reduce the concentration of harmful gases. The plates, profiles, and other main finished materials used for the production and installation of ventilation ducts and air ducts should comply with the design and relevant product standards, and apply factory inspection certificates. The materials should be inspected and accepted according to relevant standards when entering the site.

　　通風管道按材質分有：鋼板風管、鍍鋅板風管、不銹鋼通風管、玻璃鋼通風管、塑料通風管、復合材料通風管、彩鋼夾心保溫板通風管、雙面鋁箔保溫通風管、單面彩鋼保溫風管、涂膠布通風管、礦用塑料通風管等。

Ventilation ducts are classified by material: steel plate ducts, galvanized sheet ducts, stainless steel ducts, fiberglass ducts, plastic ducts, composite material ducts, color steel sandwich insulation board ducts, double-sided aluminum foil insulation ducts, single-sided color steel insulation ducts, coated fabric ducts, mining plastic ducts, etc.

　　按照通風方式，風管可分為以下幾種：

According to ventilation methods, air ducts can be divided into the following types:

　　1，風管式通風：設備簡單，靈活方便，易于拆卸，但由于斷面小，隨著管路的加長，通風阻力將增大。

1. Air duct ventilation: The equipment is simple, flexible and convenient, and easy to disassemble. However, due to the small cross-section, as the pipeline lengthens, the ventilation resistance will increase.

　　2，巷道式通風：適用于有平行導坑的長隧道，特點是通過前面的橫通道，使正洞和平行導坑組成一個循環(huán)風流系統(tǒng)，在平導坑口附近安裝通風機，將污濁空氣由平導抽出，新鮮空氣由正洞流入，形成循環(huán)風流。

2. Tunnel ventilation: suitable for long tunnels with parallel tunnels, characterized by forming a circulating air flow system between the main tunnel and parallel tunnels through the front horizontal channel. A ventilation fan is installed near the entrance of the horizontal tunnel to extract polluted air from the horizontal tunnel, and fresh air flows in from the main tunnel, forming a circulating air flow.

　　3，風墻式通風：利用隧道成洞部分空間，用磚砌或木板隔出一條風道，代替大直徑風管，以縮短風管長度，而又能增大供風量滿足通風要求，該方式適用于縮短較長，又無平行導坑可供利用，而管道式通風又難以全盤解決的情況。

3. Wind wall ventilation: Utilizing the space formed by the tunnel, a brick or wooden board is used to separate an air duct instead of a large-diameter air duct, in order to shorten the length of the air duct and increase the air supply to meet ventilation requirements. This method is suitable for situations where there is no parallel guide pit available for use, and pipeline ventilation is difficult to fully solve.
