WSFG型维纶塑胶布系列通风软管的研制与应用

The Development and Application of Type WSFG Ventilating Flexble Pipe Used in Railway Tunnelling

为了解决铁路隧道施工通风技术难题，研制了一种先进的新型通风软管及接头，泄漏率、风阻系数低，具有抗燃、抗老化、抗静电，结构简单，价格较低等优点，易于推广应用。

For solving the difficult problem of ventilation in railway tunnelling,a new ad vanced type of flexible pipe and joint is developed. With the advantage of low leakage and flow re sistance, fireproofing,ageing-resisting,cost-saving and simple in structure, the system developed is easy to be popularized in practice.
