摘要
桩底注浆能够提高钻孔桩的承载力、减少沉降量和降低工程造价等优点被广泛应用于桩基工程中,本文主要阐述桩底注浆的机理、施工工艺及其工程应用,为类似工程桩底注浆施工作参考。
Grouting at the pile tip can increase the pile bearing capacity, decrease the depression and reduce the project cost and is widely used in the pile foundation engineering. This paper mainly describes the mechanism of grouting at the pile tip and the construction technology as well as the engineering application so as to be of reference to similar engineering grouting construction.
