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。
以工法改進為探索,以工程實例為依託,在後壓漿鑽孔灌註樁工法基礎上,結閤土層具體情況對壓漿管和壓漿過程作設計改進,通過解決壓漿管的設置與註漿等問題,將壓漿的主要作用集中于防止地下水的滲透,併在同一場地先後實施瞭兩項工程,在取得瞭基本成功的結果下也暴露齣該工法的某些問題,值得工程界進一步改進與完善。

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 sup-porting. For silty clay with fine sand post grouting cement meth-od 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.
