摘要
后压浆作为增强灌注桩承载力的方法已经在施工领域广泛应用,通过临钢焦化厂二期扩建工程捣固焦煤塔灌注桩后压浆法的施工实例,得出后压浆对提高灌注桩承载力切实可行,特别是对砂砾地层尤为显著,为基础的设计和处理桩基问题提供了一种新的解决思路和措施。
As a way to increase the bearing capacity of cast-in-place piles,post grouting has been widely used in construction field.The example of the construction of slurry pressure through the two phase expansion project in the coking plant coking tower after tamping pile.After grouting,it is feasible to improve the bearing capacity of cast-in-place pile,especially for gravel stratum.It provides a new way to solve the problem of pile foundation design and treatment.
