长螺旋钻孔压灌桩在泥质粉砂岩地质条件下的施工应用分析

Application Analysis of Long Auger Drilling Bored Pile in Geological Condition of Muddy Siltstone

通过长螺旋钻孔灌压桩在广西钦州某厂房项目泥质粉砂岩地质条件下的实践应用,围绕实例中长螺旋钻孔压灌桩的整个施工过程,以相关规范为依据,说明长螺旋钻孔灌压桩与旋挖钻孔灌注桩在相同地质条件下各自的施工特点,分析长螺旋钻孔灌压桩的质量控制。为在今后类似场地长螺旋钻孔灌压桩施工提供可行性借鉴。

Through the application of long auger drilling bored pile in the geological condition of muddy siltstone in a plant project ofQinzhou,Guangxi,around the whole construction process of the long auger bored pile in the case and based on the relevant specification,the construction characteristics of the long auger drilling bored piles and the rotary drilling bored piles under the same geological conditionsare expounded and the quality control of the long auger bored piles is analyzed,so as to provide a feasible reference for the construction oflong auger bored piles in the future.
