一、前言由于工程施工者的需要,预拌混凝土性能上的要求,以及混凝土泵的改进,促使了采用混凝土泵进行浇筑作业施工方法的发展。从而使原来无法进行正常浇筑作业的现场,现在也能方便地使用混凝土泵来浇筑施 I. INTRODUCTION Due to the needs of construction workers, the requirements on the performance of ready-mixed concrete and the improvement of concrete pumps have prompted the development of construction methods using concrete pumps for pouring operations. As a result, on the spot where the original pouring work could not be performed originally, the concrete pump can be conveniently used for pouring.
