摘　　要：本文主要讲述了钢管拱混凝土倒灌顶升的施工技术,倒灌顶升施工是一顶比较复杂的工艺,其关键在于配合比设计与混凝土泵送,其难点在于如何保证混凝土泵送的连续性和泵送后混凝土的密实性;而采用自密实的补偿收缩混凝土能较好的解决混凝土泵送的连续性和密实性。This paper mainly tells the story of steel tube arch concrete poured empowerments and rise construction technology, and poured empowerments and rise construction is a top complicated process, whose key lies in the design of mix proportion and concrete pumping, and whose difficulty is how to ensure the continuity of concrete pumping and the dense sex after pumping concrete; The self-compacting compensation shrinkage concrete can better solve the concrete pumping continuity and dense sex.

关 键 词：倒灌 顶升 配合比 坍落度 检测 控制
