摘要
Abstract
The lift-up technology of concrete-filled steel tubular column is a kind of concrete pouring method. The pressure of the concrete conveying pump pushes self-compacting micro-expansion concrete into the hole at the bottom of steel tubular column until the whole steel tubular column is fully filled with concrete. This technology is superior to the traditional technology from the aspects of construction quality, safe management, progress control and cost control. The design of concrete mix proportion, selection of concrete delivery pump, major construction methods and integral benefit are analyzed and summarized.关键词
