大型混泥土排水管

       水泥管是用水泥跟鋼筋為材料,運用電線桿離心力的原理制造的一種預置管道。
       鋼筋網有焊點不牢固時就會出現跑筋和漏筋現象,使管身局部出現無筋狀態;
       成型后鋼筋網很難居中,鋼筋網是偏心的,也就是鋼筋網的保護層不均勻;此工藝需要大量的模具來保證產量,每個模具的尺寸是存在偏差的,對開式模具長時間拆裝使用也會出現較大變形,因此導致了管材的圓度、管口垂直度、管徑尺寸和管長尺寸等偏差較大,影響工程的安裝質量,出現滲漏將導致路面下陷,對管線兩側的土壤和地下水造成污染。
       混凝土水泥管養護方法

       蒸養法
       首先要修建蒸養池,一般的蒸養池需要2.5米寬.4米長.3米深,也可以根據自己的生產量和模具的大小而定尺寸,還需要鍋爐往蒸養池輸送蒸汽,蒸養池的密封度要好,蒸養池做好后就可以使用了.水泥管做好后就可以吊入蒸養池蒸養了,一般需要蒸養2.5--3.5個小時以后水泥管就凝固好了,一般溫度越高蒸養的時間就越短,蒸養的時間和蒸汽的溫度成反比.溫度越高越好

       自然養護
       自然養護就是不需要蒸養池,水泥管打完后把水泥管和模具放在露天進行自然養護,一般水泥管打完后需要一天的時間進行露天養護,第二天才能開模,開模后還需要進行4--6天的自然養護,每天還要專人對水泥管噴三次水,時間一般是上午一次,中午一次,下午一次,噴水的目的是保持水泥管的濕度使混凝土能夠自己慢慢凝固,噴水的次數也可以根據天氣情況和天氣的濕度而增加和減少噴水的次數.但是自然養護需要的模具比較多。
