But the two types of piles have their own disadvantages . in this paper , through intercrossing and combining the two constructing techniques author bring forward a new type of constructing technique - the cast - in - situ pile with expanded - base and post - pressure grouting . and referring to the existing constructing equipment , the constructing technique of the cast - in - situ pile with expanded - base and post - pressure grouting is studied 本文基于这两种桩型各自的优缺点，在扩底和后注浆两种施工工艺相互交叉、优势互补的基础上提出了一种新的灌注桩型一扩底后注浆灌注桩，并结合现有的施工方法和施工机具提出扩底后注浆灌注桩施工工艺。
