一體噴粉房　　塑料管材的優點　　塑料埋地管材在國外已經得到廣泛應用，原因在于埋地管比鑄鐵管、鋼管、水泥管等傳統埋地管材有許多優點：　　強度和剛性　　表面上塑料埋地管的強度和剛性不及水泥管，特別是鋼筋混凝土管，實際上塑料埋地管屬“柔性管”，在正確設計和鋪設施工情況下，塑料埋地管與周圍土壤共同承受負載，因此，塑料埋地管不需要達到與混凝土管等“剛性管”一樣的強度和剛性，就可以滿足埋地使用中的力學性能要求　　水力特性塑料管內壁光滑，阻力小，水流通量大，在同等口徑下塑料管的水流量比混凝土管大，地形有坡度時，塑料管的管材口徑可減小，施工量較小。　　密封性水泥管的密封性很差，國內平接口混凝土管在連接處僅靠抹一圈混凝土密封，施工中難于保證不泄漏，加之混凝土管系剛性管，稍有移動（如土壤不均勻沉降）就可造成連接處破壞，另外，水泥管使用硫化橡膠圈密封，塑料管連接用熱塑性彈性體密封圈密封，前者使用壽命比后者短，而且塑料管的連接和密封有一系列嚴格要求，能夠最大限度地保證不會發生泄漏。水泥管的壽命只有15年，塑料管的壽命長達50年-100年。生活污水、雨水等通常具有腐蝕性，工業污水的腐蝕性更大，使用金屬、水泥埋地排水管輸送，耐腐蝕性比塑料管差。有些地區室外自然環境的腐蝕性非常大，例如天津市塘沽新區圍海造地，鋪設的水泥排污管3年后就找不到了，均被海水中的鹽腐蝕掉了，只好二次再鋪設塑料管。　　鋪設施工　　塑料管質輕，長度大，接頭少，對管溝的要求低，連接方便，施工快捷，施工費用少，在城市及惡劣自然條件下優越性更加突出。　　綜合經濟性　　在綜合經濟性方面，塑料管的優勢正在被越來越多的用戶所認識。塑料管的單價雖比水泥管略高，但工程總造價卻不比水泥管高。天津市政工程設計院1992年起對UPVC雙壁波紋管，1998年起對PE雙壁波紋管在埋地排水管中應用進行了系統研究，結論為：“雙壁波紋管的工程(cheng)造價與混凝(ning)土平口管相當，比(bi)承插口混凝(ning)土管低30%。施(shi)工周期顯(xian)著縮短，經(jing)濟效益顯(xian)著”。
