摘要
以工法改进为探索,以工程实例为依托,在后压浆钻孔灌注桩工法基础上,结合土层具体情况对压浆管和压浆过程作设计改进,通过解决压浆管的设置与注浆等问题,将压浆的主要作用集中于防止地下水的渗透,并在同一场地先后实施了两项工程,在取得了基本成功的结果下也暴露出该工法的某些问题,值得工程界进一步改进与完善。
Facing practical requirement of engineering the traditional construction method of post pressure grouting pile is modified to probe to satisfy water prevention as well as soil supporting. For silty clay with fine sand post grouting cement method is altered to prevent water permeation. In the same site two engineerings were carried out successively and achieved success as a whole meanwhile some problems revealed in this method were worth improving further.
