在混凝土工程的施工过程中,混凝土拌合物的运输和浇筑是一项关键性的工作。它要求迅速、及时、保证混凝土拌和物的质量和降低劳动消耗。近年来,高层建筑在我国得到迅速的发展,在我国的高层建筑中,钢筋混凝土结构的占95％以上。对这些混凝土工程量较大的高层建筑,不论是厚大的桩基承台、箱形基础或上部结构,事实已证明,用混凝土泵进行混凝土拌合物的运输和浇筑是非常有效的。特别是经过近几年我国在泵送混凝土施工方面的实践,证明其在一些方 During the construction of concrete works, the transportation and pouring of concrete mix is ​​a key task. It requires rapid, timely, guaranteed quality of concrete mixes and reduced labor costs. In recent years, high-rise buildings have been rapidly developed in China. In China’s high-rise buildings, more than 95% of the reinforced concrete structures are occupied. For these high-rise buildings with a large amount of concrete work, whether it is a thick pile foundation platform, a box foundation or a superstructure, it has been proved that concrete pumps are very effective in transporting and pouring concrete mixes. In particular, after the practice of pumping concrete in China in recent years, it proved
