利用混凝土泵将已搅拌好的混凝土沿着管路进行输送和浇灌作业,即称混凝土泵送施工法。与过去使用的塔架、吊车料斗、小车等施工方法比较,它能进一步减轻繁重的体力劳动,缩短工期,降低工程造价。施工用混凝土的种类很多,由于构成材料不同,其可泵性有很大差别,其中尤以骨料、水泥的 The concrete pump is used to transport and water the already mixed concrete along the pipeline, which is called the concrete pumping construction method. Compared with construction methods such as towers, crane hoppers, and trolleys used in the past, it can further reduce heavy manual labor, shorten construction period, and reduce construction cost. There are many types of concrete used for construction. Because of the different materials, the pumpability is very different, especially aggregates and cement.
