重慶西站排水工程混凝土水管供應

工程案例:重慶西站排水工程混凝土水管供應

混凝土水管成型方
有離心法、振動法、滾壓法、真空作業法以及滾壓、離心和振動聯合作用的方法。為了提高混凝土管的使用性能,中國和其他許多國家較多地發展預應力混凝土壓力管。這種管子配有縱向和環向預應力鋼筋,因此具有較高的抗裂和抗滲能力。80年代,中國和其他一些國家發展了自應力鋼筋混凝土管,其主要特點是利用自應力水泥(見特種水泥)在硬化過程中的膨脹作用產生預應力,簡化了制造工藝?;炷凉芘c鋼管比較,可以大量節約鋼材,延長使用壽命,且建廠投資少,鋪設安裝方便,已在工廠、礦山、油田、港口、城市建設和農田水利工程中得到廣泛的應用。
