旋挖钻机在山区复杂回填地层桩基工程实例

Engineering example of rotary drilling rig in complex backfill stratum pile foundation in mountain area

以某垃圾发电厂桩基施工为例,该场地为山区复杂回填地层。介绍了旋挖成孔施工工艺流程及施工质量控制要点,简述了其在破岩能力、钻进速度等方面的优点,并针对孔壁问题提出了相应的技术措施。

In this paper,the pile foundation construction of a garbage power plant is taken as an example.The site is a complex backfill stratum in mountainous area.The rotary drilling construction process and the key points of construction quality control are introduced,its advantages in rock breaking and drilling speed are described,and then the corresponding technical measures are put forward in view of the hole wall problems in the construction process.
