试析水利工程施工中钻孔灌注桩后压浆操作技术和应用效果

On Grouting Operation Technology After Pile Drilling and Pouring in Water Conservancy Project Construction and Application Effect

在建筑施工中,钻孔灌注桩后压浆技术因其成熟的理论基础、较强的实用性及完善的控制手段,在水利水电及地矿工程中得到广泛应用;与传统工艺相比,钻孔灌注桩后压浆桩技术能够克服桩底沉渣的缺陷,大大提高桩基承载能力。本文对钻孔灌注桩后压浆桩具体操作技术进行了分析,结合实例对其应用效果进行了比较,证明了该工法的适用性及必要性。

Grouting technology after pile drilling and pouring is widely applied in water conservancy,hydropower and mining projects during building construction due to its mature theoretical foundation,stronger practicality and perfect control methods. Pile grouting technology after pile drilling and pouring can overcome defects of sediment at the bottom of pile compared with traditional process,thereby greatly improving the carrying capacity of pile foundation. In the paper,concrete operation technique of pile grouting after pile drilling and pouring is analyzed,and practical examples are combined for comparing the application effect. Applicability and necessity of the method are proved.
