混凝土机械化泵送已经成为全国各地主流的施工方式，其施工效率高、安全性大，一方面解放了劳动力，另一方面，降低了劳动强度。但是小编混迹个各地中发现，一些各地使用同款汽车混凝土输送泵的(de)情况下(xia)，泵(beng)送效率、工(gong)作时长有出入(ru)。小编对(dui)这类问(wen)题进(jin)行了一(yi)番研究，也跟相关技术人员咨询后，了解到在高层(ceng)施工(gong)中，布(bu)(bu)管(guan)方(fang)式不(bu)同与泵(beng)送高度存(cun)在密切联系(xi)，合理(li)有效的(de)进(jin)行高层(ceng)泵(beng)送管(guan)道布(bu)(bu)局，可以(yi)加快混(hun)凝泵(beng)送效率。一(yi)下(xia)是小编整(zheng)理(li)出来的(de)一(yi)些布(bu)(bu)管(guan)细(xi)节与方(fang)法！
