摘要
干作业旋挖成孔灌注在近些年桩基施工中有广泛应用,但由于干作业法施工过程中缺少稳定液护壁,在复杂地质情况下易出现塌孔,如不采取有效方法及时处理会影响整体施工进度,得不偿失。结合工程实例对塌孔处理技术进行阐述。
Rotary excavation and hole-forming grouting for dry work has been widely used in pile foundation construction in recent years.However,due to the lack of stabilized liquid wall protection in the construction process of dry work method,it is easy to collapse under complicated geological conditions.If effective methods and timely treatment are not taken,the overall construction progress will be affected.This paper elaborates the treatment technology of collapse hole with engineering examples.
