  通風(fēng)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(chǔ)設(shè)施。通風(fēng)管,風(fēng)管制作與安裝所用板材、型材以及其他主要成品材料,應(yīng)符合設(shè)計(jì)及相關(guān)產(chǎn)品標(biāo)準(zhǔn)的規(guī)定,并應(yīng)用出廠檢驗(yàn)合格證明,材料進(jìn)場(chǎng)時(shí)應(yīng)按有關(guān)標(biāo)準(zhǔn)進(jìn)行驗(yàn)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(fēng)管道按材質(zhì)分有:鋼板風(fēng)管、鍍鋅板風(fēng)管、不銹鋼通風(fēng)管、玻璃鋼通風(fēng)管、塑料通風(fēng)管、復(fù)合材料通風(fēng)管、彩鋼夾心保溫板通風(fēng)管、雙面鋁箔保溫通風(fēng)管、單面彩鋼保溫風(fēng)管、涂膠布通風(fēng)管、礦用塑料通風(fēng)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(fēng)方式,風(fēng)管可分為以下幾種:

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

  1,風(fēng)管式通風(fēng):設(shè)備簡(jiǎn)單,靈活方便,易于拆卸,但由于斷面小,隨著管路的加長(zhǎng),通風(fēng)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(fēng):適用于有平行導(dǎo)坑的長(zhǎng)隧道,特點(diǎn)是通過(guò)前面的橫通道,使正洞和平行導(dǎo)坑組成一個(gè)循環(huán)風(fēng)流系統(tǒng),在平導(dǎo)坑口附近安裝通風(fēng)機(jī),將污濁空氣由平導(dǎo)抽出,新鮮空氣由正洞流入,形成循環(huán)風(fēng)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(fēng)墻式通風(fēng):利用隧道成洞部分空間,用磚砌或木板隔出一條風(fēng)道,代替大直徑風(fēng)管,以縮短風(fēng)管長(zhǎng)度,而又能增大供風(fēng)量滿足通風(fēng)要求,該方式適用于縮短較長(zhǎng),又無(wú)平行導(dǎo)坑可供利用,而管道式通風(fēng)又難以全盤(pán)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.
