东北地区,严寒期较长。为加大承载力和防止冻胀,在软基础的水利工程的设计中,常采用混凝土灌注桩为基础。在钻孔灌注桩施工过程中,容易斜桩和断桩;严重影响工程质量。结合哈尔滨市防洪墙960根灌注桩的施工经验,分析产生斜桩、断桩的原因,提出了有效的处理方法。 Northeast China, cold period longer. In order to increase the bearing capacity and prevent frost heaving, concrete piles are often used as foundation in the design of soft foundation hydraulic engineering. In the process of bored pile construction, inclined pile and broken pile easily; seriously affect the quality of the project. Combining with the construction experience of 960 cast-in-situ piles in Harbin flood control wall, the reasons for generating inclined piles and broken piles are analyzed and an effective treatment method is put forward.
