摘要
全套管护壁拔桩法是一种用于清除地下空间原有桩的新工艺,该工艺具有操作简单、效率高、成本低等特点,且噪声较低,可减少对周边环境的影响。结合施工实例,介绍了全套管护壁拔桩法在实际工程中的应用,主要包括机械设备、主要施工流程、施工工艺及清桩难点等。
Full-sleeve wall protection technology is a new technology to remove old piles in underground space.This technology is featured with simple operation,high efficiency,low construction cost and relatively noise,which means minimized influence to the environment.Based on an actual project,issues involved with the application of full-sleeve wall protection technology to remove old piles under complex environment are introduced including mechanical equipment,construction process and removal difficulties.
