1，风管式通风：设备简单，灵活方便，易于拆卸，但由于断面小，随着管路的加长，通风阻力将增大。

1. Air duct ventilation: the equipment is simple, flexible and convenient, and easy to disassemble. However, due to the small section, the ventilation resistance will increase with the extension of the pipeline.

2，巷道式通风：适用于有平行导坑的长隧道，特点是通过前面的横通道，使正洞和平行导坑组成一个循环风流系统，在平导坑口附近安装通风机，将污浊空气由平导抽出，新鲜空气由正洞流入，形成循环风流。

2. Tunnel ventilation: It is applicable to long tunnels with parallel pilot tunnels. It is characterized by making the main tunnel and parallel pilot tunnels form a circulating air flow system through the front horizontal channel. A ventilator is installed near the opening of the horizontal pilot tunnel to draw out the dirty air from the horizontal pilot tunnel, and fresh air flows into the main tunnel to form a circulating air flow.

3，风墙式通风：利用隧道成洞部分空间，用砖砌或木板隔出一条风道，代替大直径风管，以缩短风管长度，而又能增大供风量满足通风要求，该方式适用于缩短较长，又无平行导坑可供利用，而管道式通风又难以全盘解决的情况。通风管道常用镀锌铁皮管道和不锈钢管道，在酸雾排气方面可进行金属管道喷塑处理再使用，也可以直接采用PP管道（防火性能不要求的情况下使用），部分小型排气、送风管道为节约成本，也可采用PVC、PPR管道作为风管。

3. Air wall ventilation: use the part of the tunnel space to separate an air duct with brick or wood to replace the large-diameter air duct, so as to shorten the length of the air duct, and increase the air supply to meet the ventilation requirements. This method is applicable to the situation that the length of the air duct is longer, and there is no parallel pilot pit available, and the duct ventilation is difficult to solve completely. Galvanized iron sheet pipes and stainless steel pipes are commonly used for ventilation pipes. In the aspect of acid mist exhaust, metal pipes can be sprayed and reused, or PP pipes can be directly used (if the fire performance is not required). In order to save costs, some small exhaust and air supply pipes can also use PVC and PPR pipes as air pipes. Donglanglongke has been specialized in the processing and installation of air ducts for 15 years, and has rich experience and professional technology and equipment in this field, which will escort you in the aspects of ventilation and exhaust, smoke exhaust, exhaust, purification and dust removal, civil air defense, and fire protection pipelines.

通风管道是为了使空气流通，降低有害气体浓度的一种市政基础设施。通风管，风管制作与安装所用板材、型材以及其他主要成品材料，应符合设计及相关产品标准的规定，并应用出厂检验合格证明，材料进场时应按有关标准进行验收。通风管道按材质分：一般有：钢板风管、镀锌板风管、不锈钢通风管、玻璃钢通风管、塑料通风管、复合材料通风管、彩钢夹心保温板通风管、双面铝箔保温通风管、单面彩钢保温风管、涂胶布通风管、矿用塑料通风管等。

The ventilation pipe is a municipal infrastructure for air circulation and reducing the concentration of harmful gases. The plates, profiles and other main finished materials used for the production and installation of ventilation pipes and air ducts shall comply with the provisions of the design and relevant product standards, and the factory inspection certificate shall be applied. The materials shall be accepted according to relevant standards when entering the site. The ventilation pipes are divided by material: generally, they are: steel plate ventilation pipes, galvanized sheet ventilation pipes, stainless steel ventilation pipes, fiberglass ventilation pipes, plastic ventilation pipes, composite ventilation pipes, color steel sandwich insulation plate ventilation pipes, double-sided aluminum foil insulation ventilation pipes, single-sided color steel insulation ventilation pipes, coated plastic ventilation pipes, mining plastic ventilation pipes, etc.

通风管道的应用一般有：净化系统送回风管、空调通风管、工业送排风通风管、消防排烟管道、餐饮排油烟管道、系统吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等。

The application of ventilation duct generally includes: purification system supply and return air duct, central air conditioning ventilation duct, industrial supply and exhaust air duct, fire smoke exhaust duct, catering oil smoke exhaust duct, environmental protection system suction and exhaust air duct, mine gas drainage pipe, mine adhesive coated cloth air duct, etc.
