柱錘沖擴樁法：

 柱(zhu)錘沖擴(kuo)樁(zhuang)法，通過(guo)人工成孔(kong)、螺旋鉆成孔(kong)、振動沉(chen)管成孔(kong)或柱(zhu)錘沖擊(ji)成孔(kong)，填入碎石、礦(kuang)渣(zha)(zha)、灰土(tu)、水泥(ni)土(tu)、渣(zha)(zha)土(tu)或CFG料(liao)等，分層夯擊(ji)，夯擴(kuo)樁(zhuang)體(ti)，河南灰土(tu)樁(zhuang)施工，擠密樁(zhuang)間(jian)土(tu)，形(xing)成復合(he)地基(ji)以提高地基(ji)承載力(li)和減小沉(chen)降。

 柱錘沖(chong)擴樁(zhuang)法，適(shi)用于雜填土(tu)、素(su)填土(tu)、粉土(tu)、砂(sha)土(tu)、粘性土(tu)地基等，因地制宜采用適(shi)當的成孔工(gong)藝、回(hui)填料(liao)和(he)夯擴工(gong)藝。對地下水(shui)位以下飽和(he)松軟土(tu)層，應通過(guo)現(xian)場試驗確定其適(shi)用性。地基處理深度不(bu)宜超(chao)過(guo)6m，復合地基承載力特(te)征值不(bu)宜超(chao)過(guo)163KPa。
