Before placing the air duct in place, the water level and elevation of all supports should be checked, and the firmness of the supports should be checked. There are two methods for placing the air duct: direct and lifting. For ducts with small cross-section and low orientation, manual positioning can be used, which only requires the installation of simple scaffolding. When the cross-section of the air duct is large and the pipe section is long, methods such as pulleys, chain blocks, and large ropes can be used for lifting. Century Star introduces that in order to facilitate the positioning of the air duct, it is generally used to hang the air duct on a scaffold and then lift it onto the air duct bracket

全部通风工程需求和水帘合作运用，在夏日酷热的时分可将车间内温度控制在28摄氏度以内。但人体的凉快感受可与空调比较，稍长时间对着水帘的人会感受冷而受不了。

All ventilation projects require cooperation with water curtains, and the temperature in the workshop can be controlled within 28 degrees Celsius during the scorching summer heat. But the coolness of the human body can be compared to air conditioning, and people who face the water curtain for a slightly longer time will feel cold and cannot bear it.

通风管道在运输过程应有防止损伤风管的保护措施。榫接风管的连接在榫口处涂胶粘剂，是为增强接头处的强度。当风管采用地面预组装后架空安装时，限制预组装的长度是为了遮免风管因自重产生的弯曲而破坏构件接口。玻璃纤维复合板风管端口为切割面时，在装配法兰连接件前应将管端切口面用胶带或胶液进行封堵，才能防止玻璃纤维外露和飞散。

Ventilation ducts should have protective measures to prevent damage to the ducts during transportation. The connection of the mortise and tenon air duct is coated with adhesive at the mortise to enhance the strength of the joint. When the air duct is installed overhead after ground pre assembly, limiting the length of pre assembly is to prevent the bending of the air duct due to its own weight from damaging the component interface. When the end of the fiberglass composite board air duct is a cutting surface, the cutting surface of the pipe end should be sealed with tape or glue before assembling the flange connection to prevent the fiberglass from being exposed and flying.
