地下室通风管道设计和施工遵循的原则有哪些?
What are the principles followed in the design and construction of basement ventilation ducts?
高层建筑一般都建筑在繁华地区,存车用地十分紧张,有时会成为该建筑使用的主要矛盾,高层建筑在地下设置汽车库已势在必行。
High rise buildings are generally built in bustling areas, and the land for storing cars is very scarce, sometimes becoming the main contradiction in the use of such buildings. It is imperative for high-rise buildings to set up underground car garages.
依据建筑的功能和容量的不同,汽车库的占用面积小到不足一层,大到可占用地下的几层。汽车库对室内的温湿度没有严格要求,通常能够使夏季不高于 30℃,冬季不低于5℃既可。但因汽车起动和行使时排放大量废气,而地下汽车库又处于封闭或半封闭状态,所以从保证人体健康的角度出发.对室内污染物的控制与排除成为主要目的,而该目的是靠通风系统的工作来达到的。现在南京通风管道也是非常不错的产品,受到了很多人的认可,使用起来好用。净化系统送回风管、空调通风管、工业送排风通风管、环保系统吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等。
According to the different functions and capacities of the building, the occupied area of the garage can range from less than one floor to several underground floors. The garage does not have strict requirements for indoor temperature and humidity, usually ensuring that it does not exceed 30 ℃ in summer and 5 ℃ in winter. However, due to the emission of a large amount of exhaust gas during the start-up and operation of cars, and the fact that underground car depots are in a closed or semi closed state, from the perspective of ensuring human health, the control and elimination of indoor pollutants have become the main purpose, which is achieved through the operation of ventilation systems. Nowadays, ventilation ducts in Nanjing are also very good products, which have been recognized by many people and are easy to use. Purification system return air duct, air conditioning ventilation duct, industrial supply and exhaust ventilation duct, environmental protection system suction and exhaust air duct, mining gas drainage pipe, mining coated fabric air duct, etc.
地下汽车库一旦发生火灾,往往会造成严重的经济损失和人员伤亡事故,而火灾中产生的大量烟气对人员的危害有时会超过火灾本身。因而地下汽车库的防火排烟设计是排风设计中一个必不可少的组成部分。通风管道为胶结料中碱玻璃纤维为增强材料、加入填充材料和改性剂等所制成的一种管材。它具有不燃烧、属不燃材料A级,耐腐蚀、强度高和重量轻等特点。在建筑工程、地下工程及工业厂房的通风中,它已经完全取代了不耐燃的玻璃钢通风管,并在逐步取代防腐性能差的镀锌铁皮通风管。
Once a fire occurs in an underground garage, it often causes serious economic losses and casualties, and the large amount of smoke generated during the fire can sometimes pose a greater threat to personnel than the fire itself. Therefore, the fire and smoke exhaust design of underground car depots is an essential component of exhaust design. Ventilation duct is a type of pipe made by using alkali glass fiber as the reinforcing material in the bonding material, adding filling materials and modifiers. It has the characteristics of non combustion, A-grade non combustible materials, corrosion resistance, high strength, and light weight. In the ventilation of construction projects, underground engineering, and industrial plants, it has completely replaced non combustible fiberglass ventilation pipes and is gradually replacing galvanized iron ventilation pipes with poor anti-corrosion performance.
