钻孔灌注桩反循环工艺探讨

摘要

随着经济的发展，国家在基础设施方面加大了投入的力度，进而促进了高层建筑的不断发展。在高层建筑、公路及铁路桥梁等工程的施工过程中，钻孔灌注桩得到广泛地应用。但是，正循环钻进、正循环清孔成孔等落后工艺在目前的钻孔灌注桩施工中使用的范围比较大，本文通过阐述反循环成孔工艺，分析其对工程质量和经济效率的影响。%With the development of economy, China has enhanced the input in infrastructure, thus promoting the continuous development of the high-rise building. Bored pile is widely used in the construction process of high-rise buildings, highway and railway bridge engineering. But the backward technologies like positive cycle drilling and positive cycle hole clearing and holing are widely used in bored pile construction. This article expatiates the reverse circulation pore forming process, and analyzes its impact on engineering quality and economic efficiency.
