摘要
分析混凝土泵送施工技术、溜管施工技术、溜槽施工技术和组合输送技术在超大超深基坑中应用的技术特点,并结合典型工程对4种混凝土输送技术在超大超深基坑超厚大体积混凝土的输送情况进行研究对比和印证,得出各种混凝土输送技术的适用对象,为类似工程提供借鉴。
This paper analyzed the technical characteristics of concrete pumping construction technology,chute construction technology,chute construction technology and combined transportation technology applied in super large and ultra-deep foundation pits,and com bined the typical engineering to 4 kinds of concrete transportation technologies in super-large and ultra-deep foundation pits.The transportation situation o f bulk concrete is studied,compared and confirmed,and the applicable objects o f various concrete transportation technologies are obtained,which can provide reference for similar projects.
