干作业超大型灌注桩在杏林湾桩基工程中的应用

The application of ultra-large type of compresol pile with dry construction in the pile foundation of Xinglin Bay project

以杏林湾营运中心工程主楼承压桩的大直径干作业超大型灌注桩为例,研究总结出一套比较科学系统的施工方法,解决了干作业超大型灌注桩成孔、成桩、安全技术措施及成桩后检测的施工工艺,确保施工质量达到要求。

Take ultra-large type of compresol pile of large diameter,dry construction compression pile in the project operation center of Xinglin Bay for instance,a scientific construction method was summarized,which can solve the problems of pore-forming,pile-forming,safety and technical measures and pile detection of ultra large bored pile for dry construction,and ensure the construction quality meets requirements.
