摘要
介绍了大直径人工挖孔桩的优点以及竖向承载力计算。结合邢钢180m2烧结机工程实践,详述其施工及检验方法,充分说明了人工挖孔桩桩端可以人工挖,施工时无震动,能凭肉眼检查地质情况,桩底无虚土,桩身混凝土质量可靠。
The advantage of digging large diameter stake hole by manpower and its vertical bearing capacity calculation are introduced. Based on the project of 180 m2 sintering machine its construction and examining method are stated in detail. It is concluded that the stake end can be dug with manpower, there is no shake when constructed, the geological condition can be checked with the naked eye, there is no loose earth on the bottom of stake, and the quality of stake body concrete is qualified.
